This book presents new theoretical perspectives on ecological community dynamics and in so doing casts fresh light on the enduring complexity-stability debate. Real ecological communities do not simply comprise diverse species and interactions, which respectively represented the nodes and links of the classic network theory. Rather, they are characterized by different types of complexity, and this book explains how this diversity of complexity is key to understanding the dynamics of ecological communities. It is shown how various properties in natural communities, such as life history, adaptation, density dependence, sex, interaction types, space, functional traits, and microbial processes, can dramatically increase the complexity in ecological communities. Furthermore, innovative methods are introduced that may be applied to cast light on very complex communities. With each chapter presenting the latest advances and approaches, the book sets the direction for future research on ecological community dynamics. It will be a "must read" for researchers and students in the field of ecology.
This book explores a specific ecosystem in depth, in order to weave a story built on place and history. It incorporates the theme of a journey to help reveal the environment-human-health-food system-problem. While drawing on a historical approach stretching back to the American colonial era, it also incorporates more contemporary scientific findings. By crafting its story around a specific place, the book makes it easier for readers to relate to the content, and to subsequently use what they learn to better understand the role of food systems at the global scale.
This book presents comprehensive information on various aspects of ecology with special reference to insects, to form a platform to design an ecologically sound insect pest management. Insects are the most dominant and diverse group of living organism on earth. Owing to their smaller size, smaller space and food requirements, more number of generation per unit time, insects serves as one of the best subject matter for studies on various ecological aspects such as chemical ecology, population dynamics, predator/parasitoid-prey interactions etc. The knowledge on various aspects of insect ecology helps in formulating an effective environmentally benign insect pest management. This book is of interest and use to the post graduate students and researchers working on various aspects of insect ecology with special emphasis on population dynamics, chemical ecology, tri tropic interactions, ecological engineering and Ecological Insect pest management.
The Tropics are home to the greatest biodiversity in the world, but tropical species are at risk due to anthropogenic activities, mainly land use change, habitat loss, invasive species, and pathogens. Over the past 20 years, the avian malaria and related parasites (Order: Haemosporida) systems have received increased attention in the tropical regions from a diverse array of research perspectives. However, to date no attempts have been made to synthesize the available information and to propose new lines of research. This book provides such a synthesis by not only focusing on the antagonistic interactions, but also by providing conceptual chapters on topics going from avian haemosporidians life cycles and study techniques, to chapters addressing current concepts on ecology and evolution. For example, a chapter synthesizing basic biogeography and ecological niche model concepts is presented, followed by one on the island biogeography of avian haemosporidians. Accordingly, researchers and professionals interested in these antagonistic interaction systems will find both an overview of the field with special emphasis on the tropics, and access to the necessary conceptual framework for various topics in ecology, evolution and systematics. Given its conceptual perspective, the book will appeal not only to readers interested in avian haemosporidians, but also to those more generally interested in the ecology, evolution and systematics of host-parasite interactions.
This book provides, for the first time, a comprehensive overview of the fundamental roles that ecological interactions play in extinction processes, bringing to light an underground of hidden pathways leading to the same dark place: biodiversity loss.We are in the midst of the sixth mass extinction. We see species declining and vanishing one after another. Poached rhinos, dolphins and whales slaughtered, pandas surviving only in captivity are strong emotional testimonials of what is happening. Yet, the main threat to natural communities may be overshadowed by the disappearance of large species, with most extinctions happening unnoticed and involving less eye-catching organisms, such as parasites and pollinators. Ecosystems hide countless, invisible wires connecting organisms in dense networks of ecological interactions. Through these networks, perturbations can propagate from one species to another, producing unpredictable effects. In worst case scenarios, the loss of one species might doom many others to extinction. Ecologists now consider such mechanisms as a fundamental - and still poorly understood - driver of the ongoing biodiversity crisis. Hidden Pathways to Extinction makes the invisible links connecting the fates of species and organisms evident, exploring why complexity can enhance ecosystem stability and yet accelerate species loss. Page after page, Strona provides convincing evidence that we are primarily responsible for the fall in biodiversity, that we are falling too, and that we need to redouble our conservation efforts now, or it won't be long before we hit the ground.
Bumblebees are familiar and charismatic insects, occurring
throughout much of the world. They are increasingly being used as a
model organism for studying a wide range of ecological and
behavioural concepts, such as social organization, optimal foraging
theories, host-parasite interactions, and pollination. Recently
they have become a focus for conservationists due to mounting
evidence of range contractions and catastrophic extinctions with
some species disappearing from entire continents (e.g. in North
America). Only by improving our understanding of their ecology can
we devise sensible plans to conserve them. The role of bumblebees
as invasive species (e.g. Bombus terrestris in Japan) has also
become topical with the growing trade in commercial bumblebee nests
for tomato pollination leading to establishment of non-native
bumblebees in a number of countries.
This book presents the facet theoretical framework as a tool for facilitating the conception of complex animal behaviour research and the design of research procedures through employing mapping sentences. Using the facet theoretical framework, this book takes a holistic view of bird behaviour. Components of bird behavior are identified and then reassembled to facilitate an understanding of the behaviour in the context of its natural occurrence. This provides new insight on both the parts of the behaviour and how these interact as a whole. The multi-faceted approach to designing, evaluating and understanding bird behavior presented offers a template that is adaptable for investigating a wide variety of avian species and different forms of behaviour. Behavioural biologists, animal and comparative psychologists, other natural and behavioural scientists, as well as students of these disciplines will find this book to be an interesting and enlightening read.
This edited book discusses Blue-Green Infrastructure (BGI) from conception to implementation in building resilience and urban sustainability. The book emphasizes on infrastructures, institutions, and perceptions as three main pillars of implementing and managing successful BGI, with a special focus on Asia. The book highlights concepts as well as field-based experiences from different parts of Asia by experts, with a special focus on advances and opportunities in advancing BGI, challenges and constraints, followed by case studies on BGI mainstreaming. It addresses sustainable water management, multiscale environmental design, environmental risk assessment, and finally understanding policy implications and concerns for BGI mainstreaming in growing urban sprawls of the region. There has been growing global momentum and recognition of Blue-Green Infrastructure (BGI) as a multifunctional Nature-based Solution (NbS) with multiple co-benefits. There is strong evidence from many urban centres of Europe, USA, China, and South Africa demonstrating that mainstreaming BGI can help in addressing growing vulnerability of urban areas by ensuring safety, resilience, and sustainability for urban residents in the warming world. This book is a timely contribution for researchers, students, scholars, urban planners, consultants, and policy makers in the fields of environment, resilience, urban planning, climate adaptation, and sustainability science.

The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.
While studies of San children have attained the peculiar status of having delineated the prototype for hunter-gatherer childhood, relatively few serious ethnographic studies of San children have been conducted since an initial flurry of research in the 1960s and 1970s. Based on the author's long-term field research among several San groups of Southern Africa, this book reconsiders hunter-gatherer childhood using "play" as a key concept. Playfulness pervades the intricate practices of caregiver-child interactions among the San: immediately after birth, mothers have extremely close contact with their babies. In addition to the mother's attentions, other people around the babies actively facilitate gymnastic behavior to soothe them. These distinctive caregiving behaviors indicate a loving, indulgent attitude towards infants. This also holds true for several language genres of the San that are used in early vocal communication. Children gradually become involved in various playful activities in groups of children of multiple ages, which is the major locus of their attachment after weaning; these playful activities show important similarities to the household and subsistence activities carried out by adults. Rejuvenating studies of San children and hunter-gatherer childhood and childrearing practices, this book aims to examine these issues in detail, ultimately providing a new perspective for the understanding of human sociality.
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), the spotted wing drosophila (SWD), is the most important pest affecting berry crop production worldwide. The global fresh fruit trade, coupled with the ability of the larvae to hide inside the fruit undetected until after transportation, facilitate their distribution. SWD is native to Asia, but is increasingly found in other regions: occurrences have been recorded in the Americas and Europe, and Africa, and the insects have the potential to adapt and become established in Oceania. Gathering the experiences of leading scientists in the management of D. suzukii around the globe, the book addresses D. suzukii monitoring; biological, chemical and cultural control; sterile insect technique (SIT); integrated pest management (IPM), and other control methods. It also discusses the use of drones, GPS, biotechnology, telemetry and other technological tools to make the management of this pest more efficient and accurate. As such, it is a valuable resource for scientists, professionals and students.
Seaweeds (macroalgae) represent the most striking living components in the Antarctic's near-shore ecosystems, especially across the West Antarctic Peninsula and adjacent islands. Due to their abundance, their central roles as primary producers and foundation organisms, and as sources of diverse metabolically active products, seaweed assemblages are fundamental to biogeochemical cycles in Antarctic coastal systems. In recent years, the imminence of climate change and the direct impacts of human beings, which are affecting vast regions of the Antarctic, have highlighted the importance of seaweed processes in connection with biodiversity, adaptation and interactions in the benthic network. Various research groups have been actively involved in the investigation of these topics. Many of these research efforts have a long tradition, while some "newcomers" have also recently contributed important new approaches to the study of these organisms, benefiting polar science as a whole. This book provides an overview of recent advances and insights gleaned over the past several years. Focusing on a timely topic and extremely valuable resource, it assesses the challenges and outlines future directions in the study of Antarctic seaweeds.
Fisheries resources are an important component of natural resources. It is an important source of high-quality animal protein and food for humans, which provides employment, economic benefits and social welfare for people engaged in fishing activities. It also has played an important role in food safety, economic development, and foreign trade. Fisheries resources economics is an important branch of both applied economics and resource economics. Its research object is fishery resources and its economic problems. The economics of fishery resources is to focus on the relationship between the demand for human economic activities and the supply of fishery resources, as well as between fishery resources and its development. This book expounds the reasons for the economic problems of fishery resources and the theoretical principles for solving them, so as to reveal the objective rules of the allocation of fishery resources in different regions and at different times, to coordinate the relationship between the utilization of fishery resources and economic development, and to realize the sustainable development of fishery economy. This book will also provide learning materials for undergraduates, graduate students and practitioners engaged in fishery resources development and scientific management.
Marine Animal Forests (MAFs) are spread all over the world. Composed by suspension feeding organisms (e.g. corals, gorgonians, sponges, bryozoans, bivalves, etc.), MAFs constitute a vast number of marine ecosystems such as coral reefs, cold water corals, sponge grounds, bivalve beds, etc. The surface covered by these systems is prominent (at the scale of the oceans of the planet), though poorly known. In a previous book (Marine Animal Forests, the ecology of benthic biodiversity hotspots), several aspects of the MAFs were described and discussed, building the basis for a holistic approach with the aim of putting these shallow and deep sea ecosystems under a common umbrella. The main target of the present book is to identify and address important topics which were not covered in the previous three volumes. Bryozoans or Polychaeta, for example, are treated in this volume, as well as hydrothermal vents ecosystems and submarine caves, the chemical ecology in MAFs or the nursery effect on these ecosystems. The vastity of the MAF concept opens new insights in the biology, physiology, biodiversity of the organisms structuring these highly biodiverse ecosystems and on the dangers threatening them (such as microplastics or the role of invasive species as an impact of their trophic ecology or distribution). In a fast changing world, in which the complexity of MAFs is at risk, we propose an in-depth analysis of many aspects that may be inspirational for future research lines in marine biology and ecology.
Many raptors, the hawks, eagles, and falcons of the world, migrate over long distances, often in impressively large numbers. Many avoid crossing wide expanses of water and follow "flyways" to optimize soaring potential. Atmospheric conditions and landscape features, including waterways and mountain ranges, funnel these birds into predictable bottlenecks through which thousands of daytime birds of prey may pass in a short time. Birders and ornithologists also congregate at these locations to observe the river of raptors passing overhead (as did hunters in the United States in the past and in some countries even today). Keith L. Bildstein has studied migrating raptors on four continents and directs the conservation science program at Hawk Mountain Sanctuary, Pennsylvania, the world's first refuge for migratory birds of prey. In this book, he details the stories and successes of twelve of the world's most important raptor-viewing spots, among them Cape May Point, New Jersey; Veracruz, Mexico; Kekoldi, Costa Rica; the Strait of Gibralter, Spain; and Elat, Israel. During peak migration, when the weather is right, the skies at these sites, as at Hawk Mountain, can fill with thousands of birds in a single field of view. Bildstein, whose knowledge of the phenomenon of raptor migration is comprehensive, provides an accessible account of the history, ecology, geography, science, and conservation aspects surrounding the migration of approximately two hundred species of raptors between their summer breeding sites and their wintering grounds. He summarizes current knowledge about how the birds' bodies handle the demands of long-distance migration and how they know where to go. Migrating Raptors of the World also includes the ecological and conservation stories of several intriguing raptor migrants, including the Turkey Vulture, Osprey, Bald Eagle, Western Honey Buzzard, Northern Harrier, Grey-faced Buzzard, Steppe Buzzard, and Amur Falcon.
The contributed volume puts emphasis on a superior role of water in (bio)systems exposed to a mechanical stimulus. It is well known that water plays an extraordinary role in our life. It feeds mammalian or other organism after distributing over its whole volume to support certain physiological and locomotive (friction-adhesion) processes to mention but two of them, both of extreme relevance. Water content, not only in the mammalian organism but also in other biosystems such as whether those of soil which is equipped with microbiome or the ones pertinent to plants, having their own natural network of water vessels, is always subjected to a force field.The decisive force field applied to the biosystems makes them biomechanically agitated irrespective of whether they are subjected to external or internal force-field conditions. It ought to be noted that the decisive mechanical factor shows up in a close relation with the space-and-time scale in which it is causing certain specific phenomena to occur.The scale problem, emphasizing the range of action of gravitational force, thus the millimeter or bigger force vs. distance scale, is supposed to enter the so-called macroscale approach to water transportation through soil or plants' roots system. It is merely related to a percolation problem, which assumes to properly inspect the random network architecture assigned to the biosystems invoked. The capillarity conditions turn out to be of prior importance, and the porous-medium effect has to be treated, and solved in a fairly approximate way.The deeper the scale is penetrated by a force-exerting and hydrated agent the more non-gravitational force fields manifest. This can be envisaged in terms of the corresponding thermodynamic (non-Newtonian) forces, and the phenomena of interest are mostly attributed to suitable changes of the osmotic pressure. In low Reynolds number conditions, thus in the (sub)micrometer distance-scale zone, they are related with the corresponding viscosity changes of the aqueous, e.g. cytoplasmatic solutions, of semi-diluted and concentrated (but also electrolytic) characteristics. For example, they can be observed in articulating systems of mammals, in their skin, and to some extent, in other living beings, such as lizards, geckos or even insects. Through their articulating devices an external mechanical stimulus is transmitted from macro- to nanoscale, wherein the corresponding osmotic-pressure conditions apply. The content of the proposed work can be distributed twofold. First, the biomechanical mammalian-type (or, similar) systems with extraordinary relevance of water for their functioning will be presented, also including a presentation of water itself as a key physicochemical system/medium. Second, the suitably chosen related systems, mainly of soil and plant addressing provenience, will be examined thoroughly. As a common denominator of all of them, it is proposed to look at their hydrophobic and/or (de)hydration effects, and how do they impact on their basic mechanical (and related, such as chemo-mechanical or piezoelectric, etc.) properties. An additional tacit assumption employed throughout the monograph concerns statistical scalability of the presented biosystems which is equivalent to take for granted a certain similarity between local and global system's properties, mostly those of mechanical nature. The presented work's chapters also focus on biodiversity and ecological aspects in the world of animals and plants, and the related systems. The chapters' contents underscore the bioinspiration as the key landmark of the proposed monograph.
The North American freshwater fish fauna is the most diverse and thoroughly researched temperate fish fauna in the world. "Ecology of North American Freshwater Fishes" is the only textbook to provide advanced undergraduate and graduate students and researchers with an up-to-date and integrated view of the ecological and evolutionary concepts, principles, and processes involved in the formation and maintenance of this fauna. "Ecology of North American Freshwater Fishes" provides readers with a broad understanding of why specific species and assemblages occur in particular places. Additionally, the text explores how individuals and species interact with each other and with their environments, how such interactions have been altered by anthropogenic impacts, and the relative success of efforts to restore damaged ecosystems. This book is designed for use in courses related to aquatic and fish ecology, fish biology, ichthyology, and related advanced ecology and conservation courses, and is divided into five sections for ease of use. Chapter summaries, supplemental reading lists, online sources, extensive figures, and color photography are included to guide readers through the material and facilitate student learning. Part 1: Faunal origins, evolution, and diversity Presents a broad picture - both spatially and temporally - of the derivation of the fauna, including global and regional geological and climatological processes and their effects on North American fishes. Part 2: Formation, maintenance, and persistence of local populations and assemblages. Focuses on how local fish populations and assemblages are formed and how they persist, or not, through time. Part 3: Form and function Deals with the relationship of body form and life history patterns as they are related to ecological functions. Part 4: Interactions among individuals and species Discusses the numerous interactions among individuals and species through communication, competition, predation, mutualism, and facilitation. Part 5: Issues in conservation. Focuses on several primary conservation issues such as flow alterations and the increasing biotic homogenization of faunas.
This book provides a detailed review of many different aspects of pathogens, from the effects of single base pair mutations to large-scale control options, bringing into a single volume over 100 years of findings from thousands of researchers worldwide. Diseases caused by soft rot Pectobacteriaceae (SRP) are a major cause of loss to crop, vegetables and ornamental plants worldwide, and have been found on all continents except Antarctica. While different aspects of the SRP have appeared in other books on plant disease, no book, until now, has been dedicated solely to them.
As sequel to Aquatic Animal Nutrition - A Mechanistic Perspective from Individuals to Generations, the present treatise on organic macro- and micronutrients continues the unique cross fertilization of aquatic ecology/ecophysiology and aquaculture. This treatise considers proteins and their constituents, carbohydrates from mono- to polysaccharides, fatty acids from free acids to fat, and waxes. It becomes obvious that these organic nutrients are more than only simple fuel for the metabolism of animals; rather, their constituents have messenger and controlling function for the actual consuming individual and even for succeeding generations. This aspect will become particularly clear by putting the organisms under consideration back into their ecosystem with their interrelationships and interdependencies. Furthermore, micronutrients, such as vitamins and nucleotides as well as exogenous enzymes, are in the focus of this volume with known and still-to-be-discovered controlling physiological and biomolecular functions. Aquatic Animal Nutrition - Organic Macro and Micro Nutrients addresses se veral gaps in nutritional research and practice. One major gap is the lack of com mon research standards and protocols for nutritional studies so that virtually incomparable approaches have to be compared. This applies also to the studied animals, since most approaches disregard intraspecific variabilities and the existence of epimutations in farmed individuals. Furthermore, recalling the Mechanistic Perspective from Individuals to Generations, dietary benefits and deficiencies have effects on succeeding generations. In most studies, this long-term and sustainable aspect is overruled by pure short-term production aspects. By comparing nutritional behavior and success of fishes and invertebrates, Aqua tic Animal Nutrition points out different metabolic pathways in these animal groups and discusses how, for instance, fishes would benefit when having some successful metabolic pathway of invertebrates. Application of novel ge ne tic techniques will help turn this vision into reality. However, a widely missing link in the current nutritional research is epigenetics regarding transgenerational heritages of acquired morphological and physiological properties. To in crease public acceptance, nutritional optimization of farmed animals based on this mechanism, rather than genetical engineering, appears promising.
This auto-translation book overviews the fish population and its research methods, help readers in understanding the concept of fish population and population identification. It divides into seven chapters according to the characteristics of the subject and the development results. Based on a systematic introduction to the basic concepts and research contents of the biology of fishery resources, the book focuses on the introduction of fish populations and research methods, life history division and early development identification, age identification and growth research, the division of sexual maturity, the determination of reproductive habits and fecundity, feeding characteristics and research methods of fish, and the mechanism of fish colony and migration. Through the study of this course, we can master the basic theory and methods of fish biology research and lay a solid foundation for future researches on fishery resources. This book can be used as a reference book for undergraduates and postgraduates who study fishery resources, as well as for those who are engaged in fishery and marine research. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content.
This book disseminates the latest results and envisages new challenges in the application of mathematics to various practical situations in biology, epidemiology, and ecology. It comprises a collection of the main results presented at the Ninth Edition of the International Workshop "Dynamical Systems Applied to Biology and Natural Sciences - DSABNS", held from 7 to 9 February 2018 at the Department of Mathematics, University of Turin, Italy. While the principal focus is ecology and epidemiology, the coverage extends even to waste recycling and a genetic application. The topics covered in the 12 peer-reviewed contributions involve such diverse mathematical tools as ordinary and partial differential equations, delay equations, stochastic equations, control, and sensitivity analysis. The book is intended to help both in disseminating the latest results and in envisaging new challenges in the application of mathematics to various practical situations in biology, epidemiology, and ecology.
Among the deep-sea marine invertebrates, pycnogonids and crustaceans represent ecologically important and most diverse groups of species. Yet both are still poorly understood. Sampling and exploring operations off the west and east coast of the Americas has significantly increased in the last two decades. However such operations are very costly and limited in number and frequency. In countries like Brazil, Canada, Chile, Colombia, Costa Rica, Mexico, Peru, the United States of America, and El Salvador a large effort has been made to explore the deep-sea resources and the rich diversity of the communities, resulting in a better understanding of the natural ecosystems on both coasts of America. Pycnogonids and many groups of deep-sea crustaceans have been intensively studied, from the smallest animals, like the mostly unknown benthic copepods to the largest decapods. This book presents new and updated information on various groups of deep-sea pycnogonids and crustaceans occurring off the American continent. Offering a valuable reference resource for scientists interested in this fascinating fauna, it includes review papers and new data on the deep-sea communities occurring off the USA, Mexico, El Salvador, Costa Rica, Colombia, Chile, Peru, Brazil and Argentina, as well as in larger areas in both the East Pacific and the West Atlantic. As such it covers most of the current deep-water research in Latin America.
This monograph is the result of eight years of bibliographical and field research concerning several behavioural ecology aspects of the Palaearctic falcons. For a while, this book grew along with "The Lanner falcon" published in 2015 and revised in 2017. In both books the main aim was to provide a clear overview of the biology and ecology of these species. In fact in the last 20 years, the number of publications on falcons has grown tremendously and, in parallel, also those belonging to the so-called "grey literature". The number of people involved is also increased by including both academics and nature lovers. Many previously published books emphasized identification, and offered little insights on the behavioural and ecological aspects of the species. Very often, the research on behavioural ecology remains closed within the confines of academic community. By contrast, a multitude of basic data is scattered in countless articles published in local magazines. Many falcon species are easy to observe and study (such as kestrels) but others are more rare and localized. In order to understand the survival strategies adopted by this group of avian predators, it is necessary not to lose sight of the overall picture. This book tries to explain the different survival strategies by examining, through a few essential chapters, some crucial aspects for all species. The first chapter provides information on the genus Falco, its genetics, evolution and morphological peculiarities. The other chapters deal with reproductive strategies, competition, exploitation of resources, dispersal patterns, communication and sociality. One of the main objectives of this book is to produce an accessible but scholarly curated source of reference. By understanding the most common species, it is possible to provide a working framework for rarer, and especially threatened, falcon species. |
