Details of a confrontation between two wild wolves Details of a confrontation between two wild wolves

A confrontation was photographed and video-taped at close range between a wild alpha mate wolf (Canis lupus) of known history and an alien adult on Ellesmere Island, Northwest Territories, Canada. For 100-110 seconds the two stood near each other, maneuvered around, and snapped at each other until the alien fled. The alpha and his mate, who suddenly joined the encounter, chased the other...

Effects of acidification on metal accumulation by aquatic plants and invertebrates. 1. Constructed wetlands Effects of acidification on metal accumulation by aquatic plants and invertebrates. 1. Constructed wetlands

Compared were concentrations of Al, Cd, Ca, Cu, Fe, Hg, Pb, Mg, Mn, Ni, P, and Zn in water, plants, and aquatic insects of three acidified (pH ∼ 5.0) and three nonacidified (pH ˜ 6.5) constructed wetlands. Concentrations of Zn in water and bur-reed (Sparganium americanum) were higher in acidified wetlands than in nonacidified wetlands. Floating nonrooted plants contained mean...

Eggs, nests, and nesting behavior of akiapolaau (Drepanidinae) Eggs, nests, and nesting behavior of akiapolaau (Drepanidinae)

We describe the fifth verified nest and first verified egg of the Akiapolaau (Hemignathus munroi), an endangered Hawaiian honeycreeper. We dispute the validity of Bryan?s (1905a) description of three eggs and two nests of the Akiapolaau. Eggs that he attributed to this species were much smaller than ours, and his nest descriptions did not match the only nest apparently belonging to the...

Monitoring neotropical migrants on managed land: When, where, why Monitoring neotropical migrants on managed land: When, where, why

Relevant wildlife monitoring on managed lands lies somewhere between monitoring everything and monitoring nothing. Knowing the population status of all birds on a managed area would be potentially useful information but would be costly to collect, but without monitoring no link between management and wildlife populations can be made. A decision making process for developing appropriate...

The influence of capture-recapture methodology on the evolution of the North American Bird Banding Program The influence of capture-recapture methodology on the evolution of the North American Bird Banding Program

Capture-recapture methodology has advanced greatly in the last twenty years and is now a major factor driving the continuing evolution of the North American bird banding program. Bird banding studies are becoming more scientific with improved study designs and analytical procedures. Researchers and managers are gaining more reliable knowledge which in turn betters the conservation of...
