This book is the second volume in a series of 4 volumes in the
Handbook of Zoology series treating morphology, anatomy,
reproduction, development, ecology, phylogeny, systematics and
taxonomy of polychaetous Annelida. In this volume a comprehensive
review of a few more derived higher taxa within Sedentaria are
given, namely Sabellida, Opheliida/Capitellida as well as
Hrabeiellidae. The former comprise annelids possessing a body
divided into two more or less distinct regions or tagmata called
thorax and abdomen. Here two groups of families are united, the
spioniform and sabelliform polychaetes. Especially Spionidae and
Sabellidae are speciose families within this group and represent
two of the largest annelid families. These animals live in various
types of burrows or tubes and all possess so-called feeding palps.
In one group these appendages are differentiated as grooved feeding
palps, whereas in the other they may form highly elaborated
circular tentacular crowns comprising a number of radioles mostly
giving off numerous filamentous pinnulae. Often additionally
colourful, the latter are also received the common names
"feather-duster worms", "flowers of the sea", "Christmas-tree
worms". Opheliida/Capitellida including five families of truly
worm-like annelids without appendages represents the contrary.
Their members burrow in soft bottom substrates and may be
classified as non-selective deposit feeders. Molecular phylogenetic
analyses have shown that Echiura or spoon worms, formerly regarded
to represent a separate phylum, are members of this group. Last not
least Hrabeiellidae is one out of only two families of
oligochaete-like terrestrial polychaetes and for this reason
received strong scientific interest.
Containing proceedings of the VIIIth International Rotifer
Symposium which was held in Collegeville, Minnesota, USA, on June
22-27 1997, this volume includes review papers and reports of
recent research findings along with the presentation of new methods
in rotifer biology. The publications contained in this volume
reflect the wide diversity of approaches, methods of analysis and
conclusions that characterize research on the Rotifera. Some of the
topics addressed are: rotifer distribution, responses to biotic and
abiotic factors, genetic profile of individuals and populations,
rotifer feeding and mating behavior, morphology, phylogeny and
taxonomy.
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.
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.
This work provides a user-friendly, species level taxonomic key
based on morphology, current nomenclature, and modern taxonomy
using molecular tools which fulfill the most pressing needs of both
researchers and environmental managers. This key arms the reader
with the tools necessary to improve their species identification
abilities. This book resolves another issue as well: the mix of
female and male characters used in keys to the calanoid copepods.
Often, during the identification process, both calanoid copepod
sexes are not available, and the user of such a key is stuck with
an uncertain identification. Here, separate male and female keys to
the calanoid copepods are provided for both the genera and species
levels.
Among the highlights of this book is the use of novel
insecticides acting on a specific site in an insect group and are
compatible with natural enemies and the environment. One of such
approaches is based on disrupting the activity of biochemical sites
acting on transcription factors such as the Helix-Loop-Helix (bHLH)
family, anti juvenile hormone (AJH) agents that target JH
biosynthetic enzymes, G-protein coupled receptors (GPCR) and
bursicon as a target for insect control. Another one is the
biotechnology or the genetic approach such as gene silencing (RNA
interference) and Bt-crops. Other sections of the book are devoted
to the plant s natural products, optical manipulation and the use
of nanotechnology for improving insect control methods."
Jellyfish', a group that includes scyphomedusae, hydromedusae,
siphonophores and ctenophores, are important zooplankton predators
throughout the world's estuaries and oceans. These beautiful
creatures have come to public attention as featured exhibits in
aquaria and in news headlines as invaders and as providers of genes
used in biomedical research. Nevertheless, jellyfish are generally
considered to be nuisances because they interfere with human
activities by stinging swimmers, clogging power plant intakes and
nets of fishermen and fish farms, and competing with fish and
eating fish eggs and larvae. There is concern that environmental
changes such as global warming, eutrophication, and over-fishing
may result in increased jellyfish populations. The literature
reviews and research papers in this volume explore the interactions
between jellyfish and humans. Papers cover the medical aspects of
jellyfish stings, jellyfish as human food and jellyfish fisheries,
interactions of jellyfish and fish, effects of environmental
changes on jellyfish, effects of introduced ctenophores on the
Black Sea ecosystem, factors causing increases or concentrations of
jellyfish, and others aspects of jellyfish ecology. This is an
important reference for students and professional marine
biologists, oceanographers, fishery scientists, and aquarists.
By providing multiple economic goods and ecosystem services, Latin
American forests play a key role in the environmental, social and
economic welfare of the region's countries. From the tropical
forests of Central America to the Mediterranean and temperate
vegetation of the southern cone, these forests face a myriad of
phytosanitary problems that negatively impact on both conservation
efforts and forest industry. This book brings together the
perspectives of several Latin American researchers on pest and
disease management. Each chapter provides modern views of the
status and management alternatives to problems as serious as the
impact of introduced exotic insects and diseases on Pinus and
Eucalyptus plantations throughout the continent, and the emergence
of novel insect outbreaks in tropical and temperate native forests
associated with global warming. It is a valuable guide for
researchers and practitioners working on forest health in Latin
America and around the world.
The book brings to light the most recent findings on the
biogeography, biodiversity, host plant induction and natural
history of gall inducing insects in the Neotropical region.We
attempt to summarize the work done so far in the region, promote
several syntheses on many aspects such as host induction, host
specialization, distribution among the several vegetation types and
zones, the origin of super hosts and the mechanisms leading to
geographical patterns in their distribution.Furthermore, the book
constructs new perspectives for deeper understanding of galling
insect evolutionary ecology and biogeopgraphy in the region."
This book is devoted to the welfare of invertebrates, which make up
99% of animal species on earth. Addressing animal welfare, we do
not often think of invertebrates; in fact we seldom consider them
to be deserving of welfare evaluation. And yet we should. Welfare
is a broad concern for any animal that we house, control or utilize
- and we utilize invertebrates a lot. The Authors start with an
emphasis on the values of non-vertebrate animals and discuss the
need for a book on the present topic. The following chapters focus
on specific taxa, tackling questions that are most appropriate to
each one. What is pain in crustaceans, and how might we prevent it?
How do we ensure that octopuses are not bored? What do bees need to
thrive, pollinate our plants and give us honey? Since invertebrates
have distinct personalities and some social animals have group
personalities, how do we consider this? And, as in the European
Union's application of welfare consideration to cephalopods, how do
the practical regulatory issues play out? We have previously
relegated invertebrates to the category 'things' and did not worry
about their treatment. New research suggest that some invertebrates
such as cephalopods and crustaceans can have pain and suffering,
might also have consciousness and awareness. Also, good welfare is
going to mean different things to spiders, bees, corals, etc. This
book is taking animal welfare in a very different direction.
Academics and students of animal welfare science, those who keep
invertebrates for scientific research or in service to the goals of
humans, as well as philosophers will find this work
thought-provoking, instructive and informative.
With over 43,000 species, spiders are the largest predacious
arthropod group. They have developed key characteristics such as
multi-purpose silk types, venoms consisting of hundreds of
components, locomotion driven by muscles and hydraulic pressure, a
highly evolved key-lock mechanism between the complex genital
structures, and many more unique features. After 300 million years
of evolutionary refinement, spiders are present in all land
habitats and represent one of the most successful groups of
terrestrial organisms. Ecophysiology combines functional and
evolutionary aspects of morphology, physiology, biochemistry and
molecular biology with ecology. Cutting-edge science in spiders
focuses on the circulatory and respiratory system, locomotion and
dispersal abilities, the immune system, endosymbionts and
pathogens, chemical communication, gland secretions, venom
components, silk structure, structure and perception of colours as
well as nutritional requirements. Spiders are valuable indicator
species in agroecosystems and for conservation biology. Modern
transfer and application technologies research spiders and their
products with respect to their value for biomimetics, material
sciences, and the agrochemical and pharmaceutical industries.
Orin McMonigle, with contributions by the late Dr. Richard L.
Hoffman, assembles the definitive resource guide with reproductive
and developmental data for those spectacular terrestrial
arthropods, the millipeds (or millipedes). Invertebrate hobbyists
can successfully culture a number of colorful and gigantic
diplopods by following specific methodologies outlined in this
book. From the world's largest African giant millipeds to the most
astoundingly colorful members of the Orders Polydesmida and
Spirobolida, there are plenty of species to attract the beginning
enthusiast or to challenge the advanced keeper.
This book is the first to integrate biological control into a
conceptual framework - ecostacking - uniting all aspects of
biological control and ecosystem services. In 2018 the "First
International Congress of Biological Control" was organised and
held in Beijing, China. The chapters highlight some of the
achievements presented at the congress, worldwide. Of particular
significance are the numerous contributions by Chinese researchers
illustrating the remarkable progress made on developing and
adopting multiple biological control strategies over vast
agricultural areas, largely replacing chemical pesticides for
sustainable agricultural and horticultural production. In many
parts of the world including Europe, fragmented research based on
short-term funding has been unable to answer to the needs to
develop sustainable long-term solutions to crop protection, while
colleagues in China have been successful in implementing programs
that exemplify the power of the ecostacking approach. Key
contributions by European and US specialists combined with the
expertise and experiences by the Chinese contributors comprise the
building blocks for the integration of biological control
approaches into the overall frame of ecostacking. This book will
lead the way to a broader, integrated adoption of biological
control techniques in sustainable pest, disease and weed management
supporting also the functioning of other key ecosystem services.

Machine learning is concerned with the analysis of large data and
multiple variables. However, it is also often more sensitive than
traditional statistical methods to analyze small data. The first
volume reviewed subjects like optimal scaling, neural networks,
factor analysis, partial least squares, discriminant analysis,
canonical analysis, and fuzzy modeling. This second volume includes
various clustering models, support vector machines, Bayesian
networks, discrete wavelet analysis, genetic programming,
association rule learning, anomaly detection, correspondence
analysis, and other subjects. Both the theoretical bases and the
step by step analyses are described for the benefit of
non-mathematical readers. Each chapter can be studied without the
need to consult other chapters. Traditional statistical tests are,
sometimes, priors to machine learning methods, and they are also,
sometimes, used as contrast tests. To those wishing to obtain more
knowledge of them, we recommend to additionally study (1)
Statistics Applied to Clinical Studies 5th Edition 2012, (2) SPSS
for Starters Part One and Two 2012, and (3) Statistical Analysis of
Clinical Data on a Pocket Calculator Part One and Two 2012, written
by the same authors, and edited by Springer, New York.
Insects, when studied from the ecological perspective, provide a
great opportunity for scientific studies emphasizing population
theory. The simple fact of being successful organisms for their
ability to colonize different habitats or even for their high
reproductive potential, increases the interest of ecologists in
conducting studies focused on population and community level.
Mathematical models are powerful tools that can capture the essence
of many biological systems and investigate ecological patterns
associated to ecological stability dependent on endogenous and
exogenous factors. This proposal comes from the idea of adding
experiences of researchers interested in working at the interface
between mathematical and computation theory and problems centered
on entomology, showing how mathematical modelling can be an
important tool for understanding population dynamics, behavior,
pest management, spatial structure and conservation.
The theme of the book is highly relevant to the current emphasis on
environment conservation, with focus on native biodiversity
conservation in agro-ecosystems. The current impetus being given to
organic farming and export oriented agri-hortculture in the country
calls for access to relevant scientific knowledge base among the
stakeholders. Research on biological pest control is more than a
century old in India. Egg parasitoids, which are mainly tiny wasps,
led by the family Trichogrammatidae, are the most widely utilized
natural enemies for biological control globally. Over thirty
countries are using these bioagents to protect over 10 million
hectares of agricultural and forestry crops from many important
insect pests. The book comprises 18 chapters, which are arranged in
continuum, commencing with basic aspects of knowledge and ending in
their utilization targets. The chapters cover broadly four areas:
bio-diversity and natural occurrence of egg parasitoids, behaviour
and adaptation of egg parasitoids, mass production and safe use of
egg parasitoids and utilisation of egg parasitoids in different
crop ecosystems. Some of the chapters cater to the needs of
discipline-wise update on the current R&D scenario-like insect
taxonomy, biotechnology, mass-production and quality control of the
target organisms - egg-parasitoids, which are useful for laboratory
scientists/researchers. There are also chapters devoted to
knowledge status and scope for utilization of egg parasitoids in
different target crops, which cater to requirements of field
entomologists and extensionists for use in their tasks of guiding
farmers/local guides. The book is different in approach, method,
structure and content and ensures holistic coverage of the topic.
The chapters are written by active and experienced workers in
different crops and aspects and co-edited by four very experienced
experts who have over three decades R&D experience in the
subject. All the authors have uniformly focussed on comprehensive
literature study and critical identification of knowledge gaps for
future R&D, thus the book is novel in outlook, up-to-date in
content and comprehensive in coverage of themes. This book will be
useful for supplementary reading for MSc Agriculture and PhD
Agriculture students, besides MSc/PhD research students in
Zoology/Environmental Biology, who are specialising in Entomology.
It would also serve as a very useful reference book for researchers
worldwide, though focus is also there on Indian work. It addresses
the special information needs of students and faculty, besides
practitioners and extensionists in the Australasia and Africa
regions and thus not limited to the R&D knowledge generated in
developed countries.
