The use of habitat structure preferenda for establishing flow regimes necessary for maintenance of fish habitat The use of habitat structure preferenda for establishing flow regimes necessary for maintenance of fish habitat
The pursuit of simplicity in the complex management of instream and out-of-stream water uses very early led to the minimum, or “base,” flow concept and the myth that a consistent methodology could be used to establish the desired minimum flow. Such a single flow value has not proven to be practical. As water becomes fully appropriated to upstream use and storage, the minimum flow, if not...

A preliminary assessment of the timing and migration of shorebirds along the northcentral Alaska Peninsula A preliminary assessment of the timing and migration of shorebirds along the northcentral Alaska Peninsula
An intensive study of post-breeding and migrating shorebirds was conducted in 1976 on a major estuary of the Alaska Peninsula at Nelson Lagoon. Twenty species were recorded, eight of them breeding on the study area. Temporal patterns of relative abundance were obtained from aerial and ground censuses. Prominent events in the seasonal southward movements were (a) congregation of non- and...

Approaches, field considerations and problems associated with radio tracking carnivores Approaches, field considerations and problems associated with radio tracking carnivores
The adaptation of radio tracking to ecological studies was a major technological advance affecting field investigations of animal movements and behavior. Carnivores have been the recipients of much attention with this new technology and study approaches have varied from simple to complex. Equipment performance has much improved over the years, but users still face many difficulties. The...

Artificial insemination of cranes with frozen semen Artificial insemination of cranes with frozen semen
For the first time (1978) artificial insemination (AI) with frozen greater sandhill crane (Grus canadensis tabida) semen resulted in fertile eggs and chicks. During the 2 year (1977-78) study, 6 of 27 eggs produced were fertile. Three chicks hatched. Semen samples used for insemination were frozen and stored in liquid nitrogen for two months or less. Recent improvements in the laboratory...
