Book excerpt: The Northern Highlands of Mexico is an increasingly important wintering area for populations of Lesser Snow Geese and Ross" Geese that nest in the Western and Central Canadian Arctic. In Mexico, the growing importance of the Northern Highlands as a wintering area for Ross" Geese and the western Central Flyway population of Lesser Snow Geese underscored the need to conduct field observations in that area and prompted the development of a joint effort involving the Mexican Secretaria de Desarrolla Social, the U.S. Fish and Wildlife Service, and the Canadian Wildlife Service. Some of the objectives were: estimate the number of white geese on the principal wintering areas in the states of Durango and Chihuahua, determine the breeding ground origin of Lesser Snow Goose stocks overwinterin in Mexico, determint ehe incidence and number of Ross' Geese among flocks of white geese, assess the quality and security of white goose wintering habitat, and identify wetland habitats of critical importance to waterfowl.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1999 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Razorbill Alca torda is one of the rarest breeding auks in North America. A number of surveys have been conducted at breeding colonies in recent years to estimate population size and trends. Summarizing the available data, we estimate that approximately 38 000 pairs of Razorbills currently breed in eastern North America. The largest concentrations of Razorbills breed on the Quebec North Shore and in coastal southern Labrador; smaller numbers breed in the Quebec portion of the gulf and estuary of the St. Lawrence River, Maine, New Brunswick, Nova Scotia, Newfoundland, and St. Pierre and Miquelon.
