Migration of radio-marked whooping cranes from the Aransas-Wood Buffalo population: Patterns of habitat use, behavior, and survival

Abstract

Use of migration stop-overs by radio-tracked whooping cranes (Grus americana) was studied in fall 1981-83 and spring 1983-84. Information on habitat use, time-activity budgets, and hazards encountered is presented for a sample of 27 individuals, including 9 radio-marked birds. Survival rate is calculated for radio-marked birds and compared with estimates for birds not radio-marked. Distribution patterns of birds for which complete stopover information is available are contrasted with distributions derived from opportunistic observations.

Proceedings of a workshop concerning walrus survey methods

In March 2000, the U.S. Fish and Wildlife Service and U.S. Geological Survey hosted a workshop to evaluate various techniques and approaches to estimate the size and trend of the Pacific walrus population. Workshop participants included American and Russian experts in walrus biology and survey design, subsistence hunters, and resource managers. Workshop participants reviewed previous efforts to survey the Pacific walrus population and identified problems that were encountered in designing and conducting those surveys. The group also summarized survey conditions by season and evaluated potential tools and techniques for surveying walrus populations.

Genetic differentiation of walleye stocks in Lake St. Clair and western Lake Erie

Allozyme data from six spawning sites of walleyes (Stizostedion vitreum vitreum) in western Lake Erie and two in Lake St. Clair demonstrated significant differences between allelic frequencies in fish from the two lakes. In contrast, differences were only slight between walleyes from different spawning sites within each lake. Of 21 presumptive genetic loci assayed electrophoretically, 4 were polymorphic enough to differentiate the populations. Allelic frequencies differentiating the stocks were stable between year classes, sexes, and sample years, showing that fry hatched in a particular area were returning there to spawn. These findings support other evidence for homing in Great Lakes walleyes.
