Physiology of Cold Adaptation in Birds
Workshop held June 1988. Thirty-nine contributions treat the central mechanisms of thermoregulation, heat production, metabolic adaptations, respiration and circulation, physiology of hypometabolism, breeding and incubation, and adaptations to cold in chicks. Annotation copyright Book News, Inc. Portland, Or.
If Hummingbirds Could Hum
"If Hummingbirds Could Hum" is a cheerful, creative look into the world of hummingbirds. This gentle poem is full of fun facts about these spunky birds. With an added section on attracting hummingbirds to your garden, and directions on what to do if you find an injured hummingbird, this book is not just entertainment for your little ones, but a resource for hummingbird lovers of all ages.
A Field Guide to Hummingbirds of North America
Covering 31 North American species, with more than 250 color photos and 33 maps, this is the most comprehensive field guide to hummingbirds. Introductory chapters cover the natural history of hummingbirds, ways to attract and feed them, and major hot spots in the United States and Canada for observing these fascinating birds. The 31 color plates illustrate 28 species, 7 hybrid combinations, 3 forms of albinism, and 4 species of sphinx moths often mistaken for hummingbirds. Species accounts provide in-depth information on plumage, molt, songs and calls, wing sounds, similar species, behavior, habitat, distribution, taxonomy, and conservation concerns. Detailed range maps show breeding, non-breeding, and year-round distribution, migration routes, and records outside expected areas of occurrence.
Evolutionary Conservation Biology
As anthropogenic environmental changes spread and intensify across the planet, conservation biologists have to analyze dynamics at large spatial and temporal scales. Ecological and evolutionary processes are then closely intertwined. In particular, evolutionary responses to anthropogenic environmental change can be so fast and pronounced that conservation biology can no longer afford to ignore them. To tackle this challenge, areas of conservation biology that are disparate ought to be integrated into a unified framework. Bringing together conservation genetics, demography, and ecology, this book introduces evolutionary conservation biology as an integrative approach to managing species in conjunction with ecological interactions and evolutionary processes. Which characteristics of species and which features of environmental change foster or hinder evolutionary responses in ecological systems? How do such responses affect population viability, community dynamics, and ecosystem functioning? Under which conditions will evolutionary responses ameliorate, rather than worsen, the impact of environmental change?
Sea Otter Conservation
Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter populations. Sea Otter Conservation brings together the vast knowledge of well-respected leaders in the field, ...
Hard Ticks (Acari: Ixodida: Ixodidae) Parasitizing Humans
Ticks of the family Ixodidae, commonly known as hard ticks, occur worldwide and are second only to mosquitoes as vectors of agents pathogenic to humans. Of the 729 currently recognized hard tick species, 283 (39%) have been implicated as human parasites, but the literature on these species is both immense and scattered, with the result that health professionals are often unable to determine whether a particular tick specimen, once identified, represents a species that is an actual or potential threat to its human host. In this book, two leading tick specialists provide a list of the species of Ixodidae that have been reported to feed on humans, with emphasis on their geographical distributio...
Veterinary Laboratory Medicine
Veterinary Laboratory Medicine covers all aspects of basic clinical biochemistry and haematology, and includes test–by–test interpretation of laboratory results, and sampling techniques. Information on the selection and use of an external laboratory is provided, as well as the establishment of the practice laboratory. Also included are detailed instructions for all the commonly required tests. The book will be ideal for practitioners who require a guide to laboratory work, and for veterinary students studying laboratory medicine and clinical pathology
