Book Description
The field of amphibian microbial ecology has greatly advanced in recent years. The work published to date has shown that amphibian skin bacterial communities can be influenced by host species, host life-history stage, environmental conditions, surrounding bacterial communities that serve as reservoirs and external biotic agents such as pathogens. As the ecology of amphibian-microbial symbiosis is a relatively new field, there are still many unanswered questions. The aim of this Research Topic is to highlight recent research on amphibian microbiomes that addresses relevant questions on the ecology of amphibian-microbe interactions. The publications gathered in this Research Topic have expanded our knowledge on the role of microbial symbionts of amphibians and have revealed novel insights that can direct the next set of research questions. We suggest that soon the field will move from the basic (and necessary) descriptions of microbial communities to more experimental approaches that include the use of omics methods and a variety of novel analytic and multivariate approaches. In addition to providing more insights into the microbial and disease ecology of amphibians, these studies may lead to effective ways to manipulate the microbiome to achieve protection from diseases, such as chytridiomycosis.

Book Description
Multicellular organisms are habitat for a diverse bacterial community (microbiome) that can often be associated with host health and well-being. To better understand that relationship I explored several ecological aspects of the host-associated microbiomes using pre- and post-metamorphic amphibians. First, I investigated the relative roles of local selection (due to host species identity) and regional effects (due to water body identity) on the community structure of the gut microbiome of tadpoles. I found that each water body represents a relatively distinct species pool of bacteria available for community assembly, making the water body more important in shaping the microbiome of tadpoles than their species identity. I then showed that the gut microbiome of tadpoles is not homogeneous throughout its gut length as there are changes in composition, abundance, richness, and diversity from the anterior to the posterior parts of the gut. Moreover, the gut microbiome of the anterior portion is unstable, i.e., it is highly influenced by exposition to external bacteria, while the microbiome of the posterior gut has higher stability. The posterior part harbors the functional microbiome that helps tadpoles with digestion. In fact, I found that most of the essential amino acids in the tadpole tissue are derived from bacteria. I then manipulated their gut microbiome and diet and found that the composition of the microbiome can have profound impacts on the performance and fitness of the tadpole, as distinct microbiomes affect growth, development, and mortality of the host. Finally, as tadpoles metamorphose and leave the water, their microbiome is reshaped due to changes in conditions related to both the environment and the host. I tested and showed that closely related species of adult amphibians have a tendency to harbor similar skin microbiome, but the same signal was not found for their gut microbiome. In summary, I found that the gut of tadpoles harbor several distinct but connected microbiomes that vary in composition, diversity, and stability and that can profoundly affect the fitness of the host. Its composition is ultimately determined by the environmental bacteria tadpoles were exposed to. For adult amphibians, closely related species have more similar skin but not gut microbiome

Book Description
Amphibians are the oldest tetrapod group and show an astonishing diversity in lifestyles, many of them being unique. However, globally, they are on a decline. Hence, their study is fundamental to understanding the evolution of diversity and conserving them. This book, authored by experts from around the world, summarizes the current knowledge on the evolutionary ecology of amphibians. The book treats biological concepts related to the evolution, ecology, physiology, immunology, behaviour, and morphology of amphibians in their different states. This book constitutes an actualized work indispensable for evolutionary ecologists and herpetologists.

Book Description
Describes the latest methodologies used to study the ecology of amphibians throughout the world. Each of the 27 chapters explains a research approach or technique, with emphasis on careful planning and the potential biases of techniques. Statistical modelling, landscape ecology, and disease are covered for the first time in a techniques handbook.

Book Description
Through its emphasis on recent research, its many summary tables, and its bibliography of more than 4,000 entries, this first modern, synthetic treatment of comparative amphibian environmental physiology emerges as the definitive reference for the field. Forty internationally respected experts review the primary data, examine current research trends, and identify productive avenues for future research.

Book Description
This volume sets out to provide an overview of recent research on all aspects of amphibian ecology and behaviour and to illustrate its application to practical conservation measures for this major group of animals. Its broad scope makes it of relevance to students of general biology, ecology and conservation, but also to professionals in industries and agencies involved with environmental issues and nature conservation.

Book Description
This book is a comprehensive reference work on the biology, management and health of crocodiles, alligators and gharials. It is applicable to both farmed and captive animals.The introductory chapter describes crocodilian anatomy, physiology, biochemistry, and behaviour. One chapter is devoted to important aspects of crocodile farming, namely nutrition; incubation of eggs; rearing; breeding; slaughter; and welfare. Subsequent chapters cover transmissible, nontransmissible and organ diseases, and diseases of eggs and hatchlings.
