Book Description
Nunavut is a land of islands, encompassing some of the most remote places on Earth. It is also home to some of the world’s most fascinating bird species. The windswept tundra, rocky shorelines, and icy waters of this thinly populated land are integral to the survival of numerous breeding and non-breeding birds, including the colourful King Eider, the stately Snowy Owl, the spritely Snow Bunting, and the globe-spanning Northern Wheatear. Birds of Nunavut is the first complete survey of every species known to occur in the territory. It is co-written by a team of eighteen experts who have conducted a combined total of 300 seasons of fieldwork in Nunavut. They document 295 species of birds (of which 145 are known to breed in the territory), presenting a wealth of information on identification, distribution, ecology, behaviour, and conservation. Lavishly illustrated with over 800 colour photographs and 155 maps, it is a visually stunning reference work on the birds that live in and visit Nunavut.

Book Description
In 1991, a workshop was held to examine the data related to declines in Canadian amphibian populations and associated causes and, in particular, to develop a protocol to address the issue. Participants were invited to present reports on the current status of knowledge on amphibians in Canada, particularly species that appear to be threatened. Summaries of this information are presented in this report, along with the factors that may be contributing to fluctuations in amphibian populations. Methodologies and tribulations involved in accurately assessing amphibian population size and recruitment are given. A framework for environmental monitoring was presented and the data needed, both intensive and extensive, was discussed.
