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.

The Biology of Tardigrades is the only modern comprehensive account of marine and freshwater tardigrades. It contains the first taxonomic review for over a decade in addition to covering every aspect of their biology.

The data in this book are new or updated, and will serve also as Origin of Life and evolutionary studies. Endospores of bacteria have a long history of use as model organisms in astrobiology, including survival in extreme environments and interplanetary transfer of life. Numerous other bacteria as well as archaea, lichens, fungi, algae and tiny animals (tardigrades, or water bears) are now being investigated for their tolerance to extreme conditions in simulated or real space environments. Experimental results from exposure studies on the International Space Station and space probes for up to 1.5 years are presented and discussed. Suggestions for extaterrestrial energy sources are also indicated. Audience Researchers and graduate students in microbiology, biochemistry, molecular biology and astrobiology, as well as anyone interested in the search for extraterrestrial life and its technical preparations.

With wonder and a sense of humor, Nature Obscura author Kelly Brenner aims to help us rediscover our connection to the natural world that is just outside our front door--we just need to know where to look. Through explorations of a rich and varied urban landscape, Brenner reveals the complex micro-habitats and surprising nature found in the middle of a city. In her hometown of Seattle, which has plowed down hills, cut through the land to connect fresh- and saltwater, and paved over much of the rest, she exposes a diverse range of strange and unknown creatures. From shore to wetland, forest to neighborhood park, and graveyard to backyard, Brenner uncovers how our land alterations have impacted nature, for good and bad, through the wildlife and plants that live alongside us, often unseen. These stories meld together, in the same way our ecosystems, species, and human history are interconnected across the urban environment.

The Appalachian Bear Center in Tennessee rescues orphaned bear cubs.

'Highly recommended' Financial Times Today we know of only a single planet that hosts life: the Earth. But across a Universe of at least 100 billion possibly habitable worlds, surely our planet isn't the only one which, like the porridge Goldilocks sought, is just right for life? Astrobiologists search the galaxy for conditions that are suitable for life to exist, focusing on similar worlds located at the perfect distance from their Sun, within the aptly named 'Goldilocks Zone'. Such a place might have liquid water on its surface, and may therefore support a thriving biosphere. What might life look like on other worlds? It is possible to make best-guesses using facts rooted in science, and by studying 'extremophiles' – organisms such as the near-indestructible water bears, which can survive in the harshest conditions that Earth, and even space, can offer. Goldilocks and the Water Bears is a tale of the origins and evolution of life, and the quest to find it on other planets, on moons, in other galaxies, and throughout the Universe.

This book offers a comprehensive study of species- and genus-level diversity and chorology of the global freshwater fauna to date. It gives a state of the art assessment of the diversity and distribution of Metazoa in the continental waters of the world.

Selected for the 2018 Bank Street College of Education Best STEM Children's Books of the Year What do the goblin shark, horseshoe crab, the "indestructible" water bear, and a handful of other bizarre animals have in common? They are all "extreme survivors," animals that still look much like their prehistoric ancestors from millions of years ago. Meet ten amazing animals that appear to have changed little in more than 100 million years. They are the rare exceptions to the rule.

A children's book featuring the Tardigrade - the world's most brilliant animal!

Eva Nine was raised by the robot Muthr. But when a marauder destroys the underground sanctuary she called home, twelve-year-old Eva is forced to flee aboveground. Eva Nine is searching for anyone else like her. She knows that other humans exist because of a very special item she treasures ~ a scrap of cardboard on which is depicted a young girl, an adult, and a robot along with the strange word "WondLa". Tony DiTerlizzi honours traditional children's literature in this totally original space age adventure: one that is as complex as an alien planet, but as simple as a child's wish for a place to belong.
