The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

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. .

Offering extensive information on tardigrades, this volume begins with a chapter on the history of tardigrades, from the first description by Goeze in 1773, until 1929, when the most comprehensive monographic approach by E. Marcus was published. Tardigrades’ organ systems, including their integument, body cavity, digestive, muscular, nervous and reproductive systems, as well as their overall external morphology, are summarized in the second chapter. Subsequent chapters present the current state of knowledge on tardigrade phylogeny, biogeography, paleontology, cytology and cytogenetics. In addition, the book provides insights into the ecology of tardigrades in marine, freshwater and terrestrial habitats. The reproduction, development and life cycles are summarized and the extraordinary environmental adaptations of encystment and cyclomorphosis, desiccation tolerance, freezing tolerance and radiation tolerance are discussed in detail. Further chapters provide an overview of key approaches in molecular tardigrade studies and describe techniques for sampling and sample processing. The book closes with a list of tardigrade taxa up to a sub-generic level, including the type species of each genus, the numbers of lower taxa in each taxon, and the main environments in which the taxa were found. Given its depth of coverage, the volume offers an invaluable resource for scientists from various disciplines who plan to research tardigrades, and for all others who are interested in these fascinating animals.

Rove beetles (Staphylinidae) are common elements of the soil biota, living in the litter and deeper soil layers. Although they are one of the most diverse and speciose groups of insects, no comprehensive books on their general evolution and ecology are as yet available. This book fills that gap, discussing significant aspects and active research examples in the fields of phylogeny and systematics, ecology and conservation, and reproduction and development. The combination of review chapters and case studies provides an excellent introduction to the biology of rove beetles and enables readers to become familiar with active research fields in this megadiverse group of beetles. Offering easy access to these fields, it also demonstrates how staphylinids are used as bioindicators in applied ecosystem research, including that concerning conservation issues. Experienced scientists and beginners alike find the diversity of subjects covered intriguing and inspiring for continuing and starting their own research. The book is intended for students and researchers in biology and zoology (entomology), including morphologists, ecologists, soil scientists, evolutionary biologists, paleontologists, biogeographers, taxonomists and systematists.

This book aims to assess, evaluate and critically analyze the methods that are currently available for a judicious pest management in durable food. It presents and analyzes a vast amount of methods that are already in use in “real world” industrial applications. After the phase-out of methyl bromide, but also the withdrawal of several insecticides and the continuously updated food safety regulations, there is a significant knowledge gap on the use of risk-reduced, ecologically-compatible control methods that can be used with success against stored-product insect species and related arthropods. The importance of integrated pest management (IPM) is growing, but the concept as practiced for stored products might differ from IPM as historically developed for field crops. This book discusses a wide variety of control strategies used for stored product management and describes some of the IPM components. The editors included chemical and non-chemical methods, as both are essential in IPM. They set the scene for more information regarding emerging issues in stored product protection, such as emerging, alien and invasive species as threats for global food security, as well as the importance of stored-product arthropods for human health. Finally, the analysis of the economics of stored product protection is presented, from theory to practice.

This book provides insights into the fascinating life of the Lesser Flamingo (Phoeniconaias minor) and describes how this enigmatic bird has adapted to the extreme conditions of tropical soda lakes and can even withstand the caustic effects of brine. However, humans are increasingly disrupting the natural cycles of these wetlands, and for these pink birds characteristic of these salt lakes, it is becoming more and more difficult to find suitable habitats, food and breeding grounds. Their fate is considered a cautionary example of man’s dealings with nature. Will the Lesser Flamingo survive in a man-made world? Flamingos are considered to be an embodiment of the Phoenix, and the author interweaves his personal experiences with and observations of the flamingos’ unusual habitats with the Phoenix motif in order to stimulate reflection on the circle of life. Written in an accessible style that combines science, biological information and the author’s own travels and fieldwork, the book also includes a wealth of captivating images. As such, it offers a unique resource for biologists and nature-loving Africa and Asia enthusiasts alike.

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.

Sound is almost always around us, anywhere, at any time, reaching our ears and stimulating our brains for better or worse. Sound can be the disturbing noise of a drill, a merry little tune sung by a friend, the song of a bird in the morning or a clap of thunder at night. The science of sound, or acoustics, studies all types of sounds and therefore covers a wide range of scientific disciplines, from pure to applied acoustics. Research dealing with acoustics requires a sound to be recorded, analyzed, manipulated and, possibly, changed. This is particularly, but not exclusively, the case in bioacoustics and ecoacoustics, two life sciences disciplines that attempt to understand and to eavesdrop on the sound produced by animals. Sound analysis and synthesis can be challenging for students, researchers and practitioners who have few skills in mathematics or physics. However, deciphering the structure of a sound can be useful in behavioral and ecological research – and also very amusing. This book is dedicated to anyone who wants to practice acoustics but does not know much about sound. Acoustic analysis and synthesis are possible, with little effort, using the free and open-source software R with a few specific packages. Combining a bit of theory, a lot of step-by-step examples and a few cases studies, this book shows beginners and experts alike how to record, read, play, decompose, visualize, parametrize, change, and synthesize sound with R, opening a new way of working in bioacoustics and ecoacoustics but also in other acoustic disciplines.
