Factors in Habitat Selection by Lake Sturgeon (Acipenser
fulvescens)
This final grant report was written by The Research
Foundation of State University of New York in conjunction
with State University of New York, College of Environmental
Science and Forestry. The study examined the diet of
different size classes of lake sturgeon to investigate
shifts in prey preference related to body size and to
determine if exotic Dreissenid mussels comprised a
significant component of the sturgeon diet. This study also
examined the apparent differences in juvenile and adult
habitat relative to preferred prey items.

Activity Patterns and Spatial Resource Selection of
the Eastern Massasauga Rattlesnake, Sistrurus c.
catenatus, in Northeastern Indiana
This report by the Center for Reptile and Amphibian
Conservation and Management, Indiana-Purdue University,
details findings from a four-year study of the Eastern
Massasauga Rattlesnake in northeastern Indiana. Patterns of
movement and habitat use were examined using radio
telemetry. Understanding the habitat requirements of the
Eastern Massasauga Rattlesnake, which is being considered
for federal listing as Threatened under the Endangered
Species Act of 1973, will guide proper fen habitat
management efforts to protect this species.

Conservation
of Biological Diversity in the Great Lakes Basin Ecosystem:
Issues and Opportunities
Biological diversity underpins the functional integrity
of the Great Lakes basin ecosystem. This document prepared
by The Nature Conservancy’s Great Lakes Program Office
provides a "first look" at the special biological diversity
of the Great Lakes basin ecosystem and the human activities
that place it at risk. The information and methods of the
Natural Heritage programs are used to identify key
biodiversity resources of the Great Lakes basin ecosystem.
The Heritage methodology provides a means of focusing action
on those elements most critical to the maintenance of
biological diversity. /report/ |
The Effect of Forest Structure on Amphibian Abundance
and Diversity in the Chicago Region
 Amphibian populations are under increasing threat in the
Chicago region due to habitat degradation and loss. This
report by the Citizens for Conservation investigates the
link between amphibian abundance and diversity and condition
of upland forest adjacent to breeding ponds. Results
indicate that hydrology is the dominant force driving
amphibian populations in upland forests in the Chicago
region, and forest structure is important only when
hydrology is suitable. Specific site management suggestions
to enhance amphibian populations are provided.
