Book Description
We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our intended audience is field ecologists in general and, in particular, wildlife and fisheries biologists who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function (RSF), where this is a function of characteristics measured on resourceunits such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.

Book Description
"This document reports on the progress towards meeting the objectives for Woodland Caribou, Boreal population (herein referred to as "boreal caribou") listed in the Recovery Strategy for the Woodland Caribou (Rangifer tarandus caribou), Boreal population in Canada (hereafter referred to as "the Recovery Strategy"; Environment Canada, 2012) from 2012 to 2017. This Progress Report should be considered as one of a linked series of documents, including: the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status report (COSEWIC, 2002, 2014), the Recovery Strategy (Environment Canada, 2012), the Action Plan for the Woodland Caribou, Boreal population in Canada: Federal Actions (hereafter referred to as "the proposed Action Plan"; Environment and Climate Change Canada (ECCC), 2017), and the Multi-species Action Plan for Pukaskwa National Park of Canada (PCA, 2017)"--Introd., p. 1.

Book Description
This book is a comprehensive presentation of health and diseases in reindeer and caribou, or just Rangifer, a key Circumarctic species with broad social and ecological value. It is an essential reference for anyone interested in the biology and health of wild or semi-domesticated reindeer and caribou, and is more broadly relevant for those with interests in other species of free-ranging and captive cervids. Beginning with a general introduction to Rangifer as a species, it then focuses on Rangifer "health" as a concept and describes the determinants of health at an individual and population level. Chapters cover a range of topics from nutrition and feeding to stress, non-infectious and infectious diseases, meat hygiene, capture and restraint, diagnosis and treatment of health issues, and finally, potential impacts of climate change on health of Rangifer. Reindeer and Caribou: Health and Disease compiles extensive research and experience-based information on issues ranging from drug doses for chemical immobilization, blood chemistry values, and raising an orphaned calf. In addition, it contains hundreds of high quality colour illustrations that contribute to its value as a diagnostic resource for recognizing various parasites, pathogens and signs of disease, both in live and dead animals. Each chapter is followed by a comprehensive list of references and a list of contact information for all the contributors, identifying world experts in the different areas of health for this circumpolar and fascinating species. This book is compulsory reading and an indispensable resource for anyone dealing with health in reindeer and caribou, including veterinarians, wildlife biologists and managers, reindeer herders/game ranchers, zoological husbandry personnel, and students with wildlife health.

Book Description
Humanity can make short work of the oceans’ creatures. In 1741, hungry explorers discovered herds of Steller’s sea cow in the Bering Strait, and in less than thirty years, the amiable beast had been harpooned into extinction. It’s a classic story, but a key fact is often omitted. Bering Island was the last redoubt of a species that had been decimated by hunting and habitat loss years before the explorers set sail. As Callum M. Roberts reveals in The Unnatural History of the Sea, the oceans’ bounty didn’t disappear overnight. While today’s fishing industry is ruthlessly efficient, intense exploitation began not in the modern era, or even with the dawn of industrialization, but in the eleventh century in medieval Europe. Roberts explores this long and colorful history of commercial fishing, taking readers around the world and through the centuries to witness the transformation of the seas. Drawing on firsthand accounts of early explorers, pirates, merchants, fishers, and travelers, the book recreates the oceans of the past: waters teeming with whales, sea lions, sea otters, turtles, and giant fish. The abundance of marine life described by fifteenth century seafarers is almost unimaginable today, but Roberts both brings it alive and artfully traces its depletion. Collapsing fisheries, he shows, are simply the latest chapter in a long history of unfettered commercialization of the seas. The story does not end with an empty ocean. Instead, Roberts describes how we might restore the splendor and prosperity of the seas through smarter management of our resources and some simple restraint. From the coasts of Florida to New Zealand, marine reserves have fostered spectacular recovery of plants and animals to levels not seen in a century. They prove that history need not repeat itself: we can leave the oceans richer than we found them.

Book Description
This study analyzes the number of forest fires in Saskatchewan, the area burned, the fire cycle, the fire season, causes of fires, potential fire intensity, and the fire climate for two types of ecological units: ecozones & ecoregions. Analyses are performed for all forested ecozones: the boreal plain, the boreal shield, & the taiga shield. For ecoregions, only those of the boreal plain were considered. The analysis is based on 20 years (1981-2000) of fire occurrence (ignition) data, a database of large (over 200 hectare) fires for 1945-2000, and 12 years (1990-2001) of daily fire weather observations. The results reveal contrasts in the fire regime of ecozones & ecoregions and illustrate important variations in the fire regime in both time & space.
