This book covers pot-pollen-the other product, besides honey,
stored in cerumen pots by Meliponini. Critical assessment is given
of stingless bee and pot-pollen biodiversity in the Americas,
Africa, Asia and Oceania. Topics addressed include historical
biogeography, cultural knowledge, bee foraging behavior,
pollination, ecological interactions, health applications,
microbiology, the natural history of bee nests, and chemical,
bioactive and individual plant components in stored pollen.
Pot-pollen maintains the livelihoods of stingless bees and provides
many interesting biological products that are just now beginning to
be understood. The Meliponini have developed particular nesting
biologies, uses of building materials, and an architecture for
pollen storage. Environmental windows provide optimal temperature
and availability of pollen sources for success in plant pollination
and pollen storage. Palynological composition and pollen taxonomy
are used to assess stingless honey bee pollination services. Pollen
processing with microorganisms in the nest modifies chemical
composition and bioactivity, and confers nutraceutical benefits to
the honey and pollen widely relished by native people. Humans have
always used stingless bees. Yet, sustainable meliponiculture
(stingless bee-keeping) projects have so far lacked a treatise on
pot-pollen, which experts provide in this transdisciplinary,
groundbreaking volume.
Losses of forests and their insect inhabitants are a major global
conservation concern, spanning tropical and temperate forest
regions throughout the world. This broad overview of Australian
forest insect conservation draws on studies from many places to
demonstrate the diversity and vulnerability of forest insects and
how their conservation may be pursued through combinations of
increased understanding, forest protection and silvicultural
management in both natural and plantation forests. The relatively
recent history of severe human disturbance to Australian forests
ensures that reasonably natural forest patches remain and serve as
'models' for many forest categories. They are also refuges for many
forest biota extirpated from the wider landscapes as forests are
lost, and merit strenuous protection from further changes, and
wider efforts to promote connectivity between otherwise isolated
remnant patches. In parallel, the recent attention to improving
forest insect conservation in harmony with insect pest management
continues to benefit from perspectives generated from
better-documented faunas elsewhere. Lessons from the northern
hemisphere, in particular, have led to revelations of the
ecological importance and vulnerability of many insect taxa in
forests, together with clear evidence that 'conservation can work'
in concert with wider forest uses. A brief outline of the variety
of Australian tropical and temperate forests and woodlands, and of
the multitude of endemic and, often, highly localised insects that
depend on them highlights needs for conservation (both of single
focal species and wider forest-dependent radiations and
assemblages). The ways in which insects contribute to sustained
ecological integrity of these complex ecosystems provide numerous
opportunities for practical conservation.
This book is a unique cross fertilization of aquatic ecology and
aquaculture. It shows how diets structure the digestive tract and
its microbiota and, in turn, the microbiota influences life history
traits of its host, including behavior. Short-term starvation can
have beneficial effects on individuals themselves and succeeding
generations which may acquire multiple stress resistances - a
mechanism strengthening the persistence of populations. From
terrestrial, but not yet from aquatic animals, it is understood
that circadian the rhythmicity makes toxins or good food. On the
long-term, the dietary basis impacts succeeding generations and can
trigger a sympatric speciation by (epi)-genetics. This volume
defines gaps in nutritional research and practice of farmed fishes
and invertebrates by referring to knowledge from marine and
freshwater biology. It also points out that dietary benefits and
deficiencies have effects on several succeeding generations,
indicating that well designed diets may have the potential to
successfully improve broodstock and breeding effort.
"A ground-breaking identification guide ... the perfect marriage of
artistic excellence, deep knowledge and, dare I say it, of
scientists' genuine affection." BRETT WESTWOOD This brand new
illustrated field guide covers all 47 species of ladybird occurring
in the British Isles in a handy and easy-to-use format.
Twenty-seven species are colourful and conspicuous and easily
recognised as ladybirds; the remaining species are more
challenging, but the clear illustrations and up-to-date text in
this guide will help to break down the identification barriers. A
useful introduction provides an overview of ladybird ecology, tips
on studying and recording, and suggested sites for finding
ladybirds. The main part of the book comprises detailed species
texts, covering field characters, food, habitats, suggested survey
methods, ranges, conservation statuses and distribution trends. An
illustrated at-a-glance identification guide and helpful pointers
for differentiating similar-looking species are also included. With
102 colour photographs and 47 distribution maps, combined with
Richard Lewington's peerless artwork, this is the definitive guide
to one of our most cherished and charismatic insect groups.
This book brings together most of the information available
concerning two species that diverged 2-3 million years ago. The
objective was to try to understand why two sibling species so
similar in several characteristics can be so different in others.
To this end, it was crucial to confront all data from their ecology
and biogeography with their behavior and DNA polymorphism.
Drosophila melanogaster and Drosophila simulans are among the two
sibling species for which a large set of data is available. In this
book, ecologists, physiologists, geneticists, behaviorists share
their data on the two sibling species, and several scenarios of
evolution are put forward to explain their similarities and
divergences. This is the first collection of essays of its kind. It
is not the final point of the analyses of these two species since
several areas remain obscure. However, the recent publication of
the complete genome of D. melanogaster opens new fields for
research. This will probably help us explain why D. melanogaster
and D. simulans are sibling species but false friends.
This book describes the evolutionary and ecological consequences of
reproductive competition for scarabaeine dung beetles. As well as
giving us insight into the private lives of these fascinating
creatures, this book shows how dung beetles can be used as model
systems for improving our general understanding of broad
evolutionary and ecological processes, and how they generate
biological diversity. Over the last few decades we have begun to
see further than ever before, with our research efforts yielding
new information at all levels of analysis, from whole organism
biology to genomics. This book brings together leading researchers
who contribute chapters that integrate our current knowledge of
phylogenetics and evolution, developmental biology, comparative
morphology, physiology, behaviour, and population and community
ecology. Dung beetle research is shedding light on the ultimate
question of how best to document and conserve the world's
biodiversity. The book will be of interest to established
researchers, university teachers, research students, conservation
biologists, and those wanting to know more about the dung beetle
taxon.
This order once encompassed all insects with a complex network of
wing veins, regardless of whether their metamorphosis was
incomplete or complete. By the early 20th century, most of the
species had been transferred to new orders, leaving only a small
percentage of the insects once assigned to the Neuroptera remaining
in that order. By the second half of the 20th century, some of the
taxonomists began to believe that the fragmentation of this order
had gone too far, and that the order Megaloptera needed to be
grouped in some way with Neuroptera, either by making them
suborders of the same order or by creating a superorder to
accommodate both. This volume provides a discussion of both taxa,
tentatively regrouping both in the order Neuroptera. While all
known species of Megaloptera in South America have completely
aquatic larval stages, few species in the suborder Planipennia,
formerly called Neuroptera sensu stricto, are aquatic during any of
their life stages. The most interesting of the exceptions are
species in the family Sisyridae, some of which develop as larvae
inside freshwater sponges.Because only a relatively small number of
species are still included in Neuroptera sensu lato, this book
provides keys to all known South American species that have been
described well enough to be identified with any degree of
certainty. Many species in the family Chloropidae, the neuropteran
family with the greatest number of recognized species in South
America, have proven to be valuable as biological controls for
insect pests in agriculture. Their importance for tropical
agriculture is another reason for including terrestrial species in
this book. The series will continue with volumes providing keys to
identify species of other South American orders, but in most cases,
only aquatic insects can be included in the keys to the species.
Documenting and understanding intricate ecological interactions
involving insects is a central need in conservation, and the
specialised and specific nature of many such associations is
displayed in this book. Their importance is exemplified in a broad
global overview of a major category of interactions, mutualisms, in
which the interdependence of species is essential for their mutual
wellbeing. The subtleties that sustain many mutualistic
relationships are still poorly understood by ecologists and
conservation managers alike. Examples from many parts of the world
and ecological regimes demonstrate the variety of mutualisms
between insect taxa, and between insects and plants, in particular,
and their significance in planning and undertaking insect
conservation - of both individual species and the wider contexts on
which they depend. Several taxonomic groups, notably ants, lycaenid
butterflies and sucking bugs, help to demonstrate the evolution and
flexibility of mutualistic interactions, whilst fundamental
processes such as pollination emphasise the central roles of,
often, highly specific partnerships. This compilation brings
together a wide range of relevant cases and contexts, with
implications for practical insect conservation and increasing
awareness of the roles of co-adaptations of behaviour and ecology
as adjuncts to designing optimal conservation plans. The three
major themes deal with the meanings and mechanisms of mutualisms,
the classic mutualisms that involve insect partners, and the
environmental and conservation lessons that flow from these and
have potential to facilitate and improve insect conservation
practice. The broader ecological perspective advances the
transition from primary focus on single species toward consequently
enhancing wider ecological contexts in which insect diversity can
thrive.
This book is devoted to the ichnology of insects, and associated
trace fossils, in soils and paleosols. The traces described here,
mostly nests and pupation chambers, include one of the most complex
architectures produced by animals. Chapters explore the walls,
shapes and fillings of trace fossils followed by their
classifications and ichnotaxonomy. Detailed descriptions and
interpretations for different groups of insects like bees, ants,
termites, dung beetles and wasps are also provided. Chapters also
highlight the the paleoenvironmental significance of insect trace
fossils in paleosols for paleontological reconstructions,
sedimentological interpretation, and ichnofabrics analysis. Readers
will discover how insect trace fossils act as physical evidence for
reconstructing the evolution of behavior, phylogenies, past
geographical distributions, and to know how insects achieved some
of the more complex architectures. The book will appeal to
researchers and graduate students in ichnology, sedimentology,
paleopedology, and entomology and readers interested in insect
architecture.
Acarology - the study of mites and ticks, is a subdiscipline of
Zoology, and is many times considered in the field of Entomology
(the study of insects). Mites and ticks are distributed throughout
the world and inhabit almost every ecosystem (both terrestrial and
aquatic) including grassland soils. More than 55,000 species of
mites and ticks are already described. Mites and ticks directly
affects humans as pests of different crops, fruit plants, vegetable
crops and field crops; as parasites of human beings, veterinary
animals, poultry and pets; pests of stored grains and other
products; mushrooms and cheese; and as parasites of honeybees. Mite
infestations are responsible for economic losses worth billions of
dollars in terms of reduced crop yields and lowered quality of
produce. Many species of mites serve as vectors of various plant
diseases; some species of ticks cause losses through blood feeding
and by transmitting many diseases among man and animals. House-dust
mite allergies, and tick bite allergies are also common in many
parts of the world.Present Book, "Fundamentals of Applied
Acarology," is written keeping in view non-availability of any
standard text dealing in different aspects of acarology at one
place. Separate chapters in this book are devoted to Importance of
Acarology, Historical account, acarine technology, morphology and
anatomy of Acari; Feeding, Development and Reproduction. Molecular
developments in relation to mites and ticks are also discussed.
Role of mites and ticks in Quarantines of plants and animals;
forensic/criminal investigations; and importance of accidental
acarophagy are discussed in detail. Safe usage of pesticides based
on their mode of action (IRAC's Groups), development of acaricide
resistance and measures to mitigate it are discussed. Mite pests of
fruit trees, vegetable plants, and floricultural plants; field
crops; mite problems in greenhouses/polyhouses; and mite problems
encountered under organic cultivation of plants; and their
management through minimum usage of pesticides are emphasized. Role
of different predaceous mites in controlling plant pests like
thrips, aphids and scale insects is elaborately discussed.
Biological control of phytophagous mites is discussed in detail.
Different animal parasitic mites and ticks are discussed from
veterinary and medical point of view.At the end of each chapter,
many important references for further reading; and Electronic
References (ER) in the form of youtube links and other weblinks are
given to understand fully how these tiny creatures look like;
behave, feed and reproduce; nature of damage they cause to plants
and animals; and measures to mitigate them. Weblinks will stimulate
interest in the readers for more information about different mites
and ticks. The knowledge contained in the book may prove as best
material for "General and Applied Acarology" course for graduate
and post-graduate levels, teachers and researchers in entomology,
pest control advisors, professional entomologists, pesticide
industry managers, policy planners, and others having interest in
mites and ticks.
Arthropods are invertebrates that constitute over 90% of the animal
kingdom, and their bio-ecology is closely linked with global
functioning and survival. Arthropods play an important role in
maintaining the health of ecosystems, provide livelihoods and
nutrition to human communities, and are important indicators of
environmental change. Yet the population trends of several
arthropods species show them to be in decline. Arthropods
constitute a dominant group with 1.2 million species influencing
earth's biodiversity. Among arthropods, insects are predominant,
with ca. 1 million species and having evolved some 350 million
years ago. Arthropods are closely associated with living and
non-living entities alike, making the ecosystem services they
provide crucially important. In order to be effective, plans for
the conservation of arthropods and ecosystems should include a
mixture of strategies like protecting key habitats and genomic
studies to formulate relevant policies for in situ and ex situ
conservation. This two-volume book focuses on capturing the
essentials of arthropod inventories, biology, and
conservation.Further, it seeks to identify the mechanisms by which
arthropod populations can be sustained in terrestrial and aquatic
ecosystems, and by means of which certain problematic species be
managed without producing harmful environmental side-effects. This
edited compilation includes chapters contributed by over 80
biologists on a wide range of topics embracing the diversity,
distribution, utility and conservation of arthropods and select
groups of insect taxa. More importantly, it describes in detail the
mechanisms of sustaining arthropod ecosystems, services and
populations. It addresses the contribution of modern biological
tools such as molecular and genetic techniques regulating gene
expression, as well as conventional, indigenous practices in
arthropod conservation. The contributors reiterate the importance
of documenting and understanding the biology of arthropods from a
holistic perspective before addressing conservation issues at
large. This book offers a valuable resource for all zoologists,
entomologists, ecologists, conservation biologists, policy makers,
teachers and students interested in the conservation of biological
resources.

This overview of the roles of alien species in insect conservation
brings together information, evidence and examples from many parts
of the world to illustrate their impacts (often severe, but in many
cases poorly understood and unpredictable) as one of the primary
drivers of species declines, ecological changes and biotic
homogenisation. Both accidental and deliberate movements of species
are involved, with alien invasive plants and insects the major
groups of concern for their influences on native insects and their
environments. Risk assessments, stimulated largely through fears of
non-target impacts of classical biological control agents
introduced for pest management, have provided valuable lessons for
wider conservation biology. They emphasise the needs for effective
biosecurity, risk avoidance and minimisation, and evaluation and
management of alien invasive species as both major components of
many insect species conservation programmes and harbingers of
change in invaded communities. The spread of highly adaptable
ecological generalist invasive species, which are commonly
difficult to detect or monitor, can be linked to declines and
losses of numerous localised ecologically specialised insects and
disruptions to intricate ecological interactions and functions, and
create novel interactions with far-reaching consequences for the
receiving environments. Understanding invasion processes and
predicting impacts of alien species on susceptible native insects
is an important theme in practical insect conservation.
Insect Hearing provides a broadly based view of the functions,
mechanisms, and evolution of hearing in insects. With a single
exception, the chapters focus on problems of hearing and their
solutions, rather than being focused on particular taxa. The
exception, hearing in Drosophila, is justified because, due to its
ever growing toolbox of genetic and optical techniques, Drosophila
is rapidly becoming one of the most important model systems in
neurobiology, including the neurobiology of hearing. Auditory
systems, whether insectan or vertebrate, must perform a number of
basic tasks: capturing mechanical stimuli and transducing these
into neural activity, representing the timing and frequency of
sound signals, distinguishing between behaviorally relevant signals
and other sounds and localizing sound sources. Studying how these
are accomplished in insects offers a valuable comparative view that
helps to reveal general principles of auditory function.
This book covers advanced concepts and creative ideas with regard
to insect biorational control and insecticide resistance
management. Some chapters present and summarize general strategies
or tactics for managing insect pests such as the principles of IPM
in various crop systems and biorational control of insect pests,
advances in organic farming, alternative strategies for controlling
orchard and field-crop pests. Other chapters cover alternative
methods for controlling pests such as disruption of insect
reproductive systems and utilization of semiochemicals and
diatomaceous earth formulations, and developing bioacoustic methods
for mating disruption. Another part is devoted to insecticide
resistance: mechanisms and novel approaches for managing insect
resistance in agriculture and in public health.
In medical and health care the scientific method is little used,
and statistical software programs are experienced as black box
programs producing lots of p-values, but little answers to
scientific questions. The pocket calculator analyses appears to be,
particularly, appreciated, because they enable medical and health
professionals and students for the first time to understand the
scientific methods of statistical reasoning and hypothesis testing.
So much so, that it can start something like a new dimension in
their professional world. In addition, a number of statistical
methods like power calculations and required sample size
calculations can be performed more easily on a pocket calculator,
than using a software program. Also, there are some specific
advantages of the pocket calculator method. You better understand
what you are doing. The pocket calculator works faster, because far
less steps have to be taken, averages can be used. The current
nonmathematical book is complementary to the nonmathematical "SPSS
for Starters and 2nd Levelers" (Springer Heidelberg Germany 2015,
from the same authors), and can very well be used as its daily
companion.
Wetlands are among the world's most valuable and most threatened
habitats, and in these crucially important ecosystems, the
invertebrate fauna holds a focal position. Most of the biological
diversity in wetlands is found within resident invertebrate
assemblages, and those invertebrates are the primary trophic link
between lower plants and higher vertebrates (e.g. amphibians, fish,
and birds). As such, most scientists, managers, consultants, and
students who work in the world's wetlands should become better
informed about the invertebrate components in their habitats of
interest. Our book serves to fill this need by assembling the
world's most prominent ecologists working on freshwater wetland
invertebrates, and having them provide authoritative perspectives
on each the world's most important freshwater wetland types. The
initial chapter of the book provides a primer on freshwater wetland
invertebrates, including how they are uniquely adapted for life in
wetland environments and how they contribute to important
ecological functions in wetland ecosystems. The next 15 chapters
deal with invertebrates in the major wetlands across the globe
(rock pools, alpine ponds, temperate temporary ponds, Mediterranean
temporary ponds, turloughs, peatlands, permanent marshes, Great
Lakes marshes, Everglades, springs, beaver ponds, temperate
floodplains, neotropical floodplains, created wetlands, waterfowl
marshes), each chapter written by groups of prominent scientists
intimately knowledgeable about the individual wetland types. Each
chapter reviews the relevant literature, provides a synthesis of
the most important ecological controls on the resident invertebrate
fauna, and highlights important conservation concerns. The final
chapter synthesizes the 15 habitat-based chapters, providing a
macroscopic perspective on natural variation of invertebrate
assemblage structure across the world's wetlands and a paradigm for
understanding how global variation and environmental factors shape
wetland invertebrate communities.
Insect and disease issues are often specific to the Mediterranean
forest systems rather than shared with the temperate forests. In
addition to the specific native insects and diseases, the forests
are subject to the invasion of exotic species. The forests are also
at risk from high degrees of human activity, including changing
patterns of forest fires, land management activities, intensive
plantation forestry using introduced timber species from other
Mediterranean climate zones, and atmospheric deposition. Combined
with elements of global climate change that may disproportionately
affect Mediterranean climate systems, this creates a number of
significant management issues that are unique to the Mediterranean
forests. It is our goal that the information contained in this
volume will contribute to understanding the unique aspects of
Mediterranean forest systems and to protecting these critical
resources.
Thanks to the application of new technologies such as whole-genome
sequencing, analysis of transcriptome and proteome of insect pest
to agriculture, great progress has been made in understanding the
life style, reproduction, evolution and nuisance to crops caused by
insect pests such as aphids, planthoppers, and whiteflies. We
believe that time has come to summarize progress and to have a
glance over the horizon. In this Book experts in the field discuss
novel means to increase the different kinds of resistances of
plants to better limit the effects of pest, to understand and
disturb the hormonal regulation of embryogenesis, molting,
metamorphosis and reproduction, to determine the function of insect
genes in diverse processes such as metabolism, interaction with
plants, virus transmission, development, and adaptation to a
changing environment. The knowledge presented here is discussed
with the aim of further improving control strategies of insect
