In most habitats, adaptations are the single most obvious aspects of an organism's phenotype. However, the most obvious feature of many subterranean animals are losses, not adaptations. Even Darwin saw subterranean animals as degenerates: examples of eyelessness and loss of structure in general. For him, the explanation was a straightforward Lamarc

The unprecedented level of diversity recorded among the clones of self-fertilizing gynogenetic unisexuals and self-fertilizing simultaneous hermaphrodites challenges current ideas on the predominant role of recombination in promoting evolution of biological diversity. Though limited to a few species, the existence of self-fertilizing and cycli

Shallow subterranean habitats (SSHs) are areas of habitable space that are less than 10 m in depth from the surface. These range from large areas such as shallow caves and lava tubes, to tiny areas such as cracks in ceilings, or spaces in soil. Whilst being very different in many ways, they are often bound together by shared characteristics of the habitats and their faunas, and their study can help us to understand subterranean habitats in general. This book concentrates on the more typical SSHs of intermediate size (seepage springs, spaces between rocks, cracks in lava etc.), describing the habitats, their fauna, and the ecological and evolutionary questions posed. Similarities and differences between the habitats are considered and discussed in a broader ecological and evolutionary context. The book is mainly aimed at students and researchers in the field of subterranean biology, but will also be of interest to a wider range of ecologists, evolutionary biologists, freshwater biologists, and conservationists. There will also be an audience of environmental professionals.

A deep-dive into the evolutionary biology, biogeography, and conservation of the most elusive subterranean creatures in the world. Far from the austere, sparsely populated ecosystems often conjured in the imagination, caves host some of the most mysterious and biodiverse natural systems in the world. Subterranean environments, however, are the least explored terrestrial habitats, contributing to misconceptions about their inhabitants. Edited by cave scientist and conservation ecologist Dr. J. Judson Wynne, Cave Biodiversity explores both the evolution and the conservation of subterrestrial-dwelling fauna. Covering both vertebrates and invertebrates, including mollusks, fishes, amphibians, arthropods, and other troglobionts, this volume brings together ichthyologists, entomologists, ecologists, herpetologists, and conservationists to provide a nuanced picture of life beneath the earth's surface. Broad chapters covering biotic and abiotic factors that influence evolution and support biodiversity precede chapters dedicated to specific taxa, highlighting phylogenetics and morphology, and delving into zoogeography, habitat, ecology, and dispersal mechanisms for each. Considerations for conservation of these fascinating, often bizarre, and often highly sensitive subterranean creatures are emphasized throughout. Cave Biodiversity aims to synthesize the principles of subterranean evolutionary biology and diversity through in-depth case studies of some of the most captivating and imperiled taxonomic groups in the world. Employing a multidisciplinary approach involving systematics, genetics, ecology, biogeography, evolutionary biology, and conservation science, Cave Biodiversity will be of keen interest to evolutionary biologists, ecologists, conservation biologists, and cave scientists, as well as advanced undergraduate and graduate students.

This book summarizes the key adaptations enabling extremophile fishes to survive under harsh environmental conditions. It reviews the most recent research on acidic, Antarctic, cave, desert, hypersaline, hypoxic, temporary, and fast-flowing habitats, as well as naturally and anthropogenically toxic waters, while pointing out generalities that are evident across different study systems. Knowledge of the different adaptations that allow fish to cope with stressful environmental conditions furthers our understanding of basic physiological, ecological, and evolutionary principles. In several cases, evidence is provided for how the adaptation to extreme environments promotes the emergence of new species. Furthermore, a link is made to conservation biology, and how human activities have exacerbated existing extreme environments and created new ones. The book concludes with a discussion of major open questions in our understanding of the ecology and evolution of life in extreme environments.

The history of biology is populated by numerous model species or organisms. But few vertebrate groups have aided evolutionary and ecological research more than the live-bearing fishes of the family Poeciliidae. Found throughout tropical and subtropical waters, poeciliids exhibit a fascinating variety of reproductive specializations, including viviparity, matrotrophy, unisexual reproduction, and alternative mating strategies, making them ideal models for research on patterns and processes in ecology, behavior, and evolution. Ecology and Evolution of Poeciliid Fishes is a much-needed overview of the scientific potential and understanding of these live-bearing fishes. Chapters by leading researchers take up a wide range of topics, including the evolution of unisexual reproduction, life in extreme environments, life-history evolution, and genetics. Designed to provide a single and highly approachable reference, Ecology and Evolution of Poeciliid Fishes will appeal to students and specialists interested in all aspects of evolutionary ecology.

Hypogean (cave, artesian) fishes have fascinated researchers even before they were described in the scientific literature in 1842. Since then, a number of scientists have used them to justify their own evolutionary ideas, from neo-Lamarckism to neo-Darwinism, from neutral evolution to selectionist approaches. Research in recent years has shown that these fishes are much more complex in their adaptations to the subterranean environment than previously believed: there are those with features expected from living in total darkness (complete blindness and depigmentation) and poor in nutrients (extremely low metabolic rates); others differ very little, if any, from their epigean (surface) ancestors in their morphology and physiology (but not so in their behavior). Some of them even live in nutrient-rich environments. Actually, one of the most overlooked facets of these animals is that there are more species of hypogean fishes without troglomorphisms (blindness, depigmentation) than with troglomorphic ones. The study of these apparently `unadapted' fishes is providing new insights into our understanding of the evolution of phenotypic characters, founding effect, behavioral, and physiological adaptations. The 86 species of troglomorphic fishes described so far belong to 18 different families, many of which would hardly fit the notion that they were 'preadapted' to conquer the underground environment. Further, many troglomorphic `species' show very little genotypic differentiation when compared with their putative ancestors, indicating that massive phenotype changes can be achieved via little genetic reorganization, a reorganization that mostly affects regulatory genes. These and many other topics are discussed in this volume containing 29 papers, written by 41 authors from 9 countries. Hopefully, this volume will convince many other researchers that hypogean fishes represent a unique opportunity to study a concept in evolutionary biology that is only superficially understood: convergent evolution.

Among all vertebrates, gobies are second in diversity only to the teleost family Cyprinidae. The Gobiidae consists of more than 200 genera and nearly 2,000 species and make up the largest family of marine fishes. Gobies account for as much as 50% of the energy flow in coral reef communities. Their small size, ability to adapt to numerous ecological
