Relative newcomers within the story of evolution, mammals are hugely successful and have colonized land, water, and air. Tom Kemp discusses the great diversity of mammalian species, and looks at how their very disparate characteristics, physiologies, and behaviours are all largely driven by one uniting factor: endothermy, or warm-bloodedness.
Following the success of earlier ‘Quick Guide’ books, this slim little volume tackles one of the few groups of mammals that can fly. Divided into large fruit bats and smaller insect-eating bats, this ultimate quick identification guide covers Africa’s 12 bat families. An informative introduction touches on evolution, flight, echolocation and reproduction, demystifying an animal that is all too often misunderstood. The text describes the facial characteristics and wing shapes common to each family and points out features that can help to distinguish between them. But it is the photographs and annotated line drawings that are most useful for identification. They include bats in flight and roosting sites, and close-ups of facial structures and wings that highlight key diagnostic attributes. An added extra is a photographic section showing the skulls of a variety bats.
"This book covers information (life cycle, appearance, habitat) about the vampire bat. Each chapter discusses an aspect of the vampire bat's life, comparing the bat to a similar mammal and to a very different mammal."--
This book provides a synthesis of all that is known about the biology of gliding mammals. It includes a brief description of each species, together with a map and a full-colour painting. It outlines the origins and biogeography of each group of gliding mammals and examines the incredible physical adaptations.
"On the Wing is the first book to take a comprehensive look at the evolution of flight in all four groups of powered flyers: insects, pterosaurs, birds, and bats."--Book jacket.
This book offers a new explanation for the development of flight in mammals and offers detailed morphological descriptions of mammals with flapping flight. The skeletomuscular apparatus of the shoulder girdle and forelimbs of tree shrews, flying lemurs and bats is described in detail. Special attention is paid to the recognition of peculiar features of the skeleton and joints. For the basic locomotor patterns of flying lemurs and bats, the kinematic models of the shoulder girdle elements are developed. The most important locomotor postures of these animals are analyzed by means of statics. The key structural characters of the shoulder girdle and forelimbs of flying lemurs and bats, the formation of which provided transition of mammals from terrestrial locomotion to gliding and then, to flapping flight, are recognized. The concept is proposed that preadaptations preceding the acquisition of flapping flight could have come from widely sprawled forelimb posture while gliding from tree to tree and running up the thick trunks. It is shown that flying lemur is an adequate morphofunctional model for an ancestral stage of bats. The evolutionary ecomorphological scenario describing probable transformational stages of typical parasagittal limbs of chiropteran ancestors into wings is developed.
Wings carry tiny insects, fluttering butterflies, and backyard birds, and they even once propelled some dinosaurs up and through the skies. Find out how, when, and why birds and beasts have taken to the air, and discover how wings work in this informative and brilliantly illustrated book about flight.
Explore the Everyday Lives of Bats! Bats have been misunderstood for generations, yet they are essential to a healthy ecosystem. From insect control to pollination services, we need bats more than most people know. Bat Basics separates fact from fiction in a fascinating, fun guide to the world’s only flying mammals. Author Karen Krebbs has been studying bats for more than 30 years. She lectures, teaches, and even trains government workers on the subject—and now she’s sharing her expertise with you. Learn the Bat Basics, such as how they use echolocation, why they hibernate, and what they eat. Discover bat myths that you probably thought were true. Find out how to bat-proof a house. Then turn to the field guide section, and identify a variety of common and important-to-know species. Projects, activities, and tips for helping the bat population round out this comprehensive guide. Get Bat Basics, and read all about why bats should be celebrated—not feared.
Environmental conditions change considerably in the course of 24 h with respect to abiotic factors and intra- and interspecific interactions. These changes result in limited time windows of opportunity for animal activities and, hence, the question of when to do what is subject to fitness maximisation. This volume gives a current overview of theoretical considerations and empirical findings of activity patterns in small mammals, a group in which the energetic and ecological constraints are particularly severe and the diversity of activity patterns is particularly high. Following a comparative ecological approach, for the first time activity timing is consequently treated in terms of behavioural and evolutionary ecology, providing the conceptual framework for chronoecology as a new subdiscipline within behavioural ecology. An extensive Appendix gives an introduction to methods of activity modelling and to tools for statistical pattern analysis.
Explore some of the most peculiar and hideous animals in the skies in this volume. Easy-to-digest text accompanies harder-to-stomach photographs, which will surely attract more reluctant readers. Supplemented with a further reading section and a list of web resources to encourage readers to keep learning after closing the cover.
