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.
Perhaps the most surprising works by Nancy Graves (1939-1995) are her life-size sculptures of camels and dromedaries. Made of wax, fiberglass, jute, and animal skins in the late sixties, they also question the principles behind true-to-nature renditions and Pop Art alike. Graves later used NASA weather maps and maps of the moon in her works, while also citing paleontology and anthropology, art history, and artifacts from other cultures. She combined Conceptual Art with Land Art and New Figuration, advanced research arts and the art film, and made important contributions to gender research. This publication presents the artist's multifaceted oeuvre and examines its relationship to the works of her contemporaries and role models, while undertaking a reevaluation of its significance in terms of art history. 0Exhibition: Ludwig Forum für Internationale Kunst, Aachen, Germany (13.10.2013-16.2.2014). 0.
