Abstract:: ... A series of 112 arctic birds representing five species (golden plover, western sandpiper, arctic tern, redpoll, and Lapland Longspur) was taken near Cape Thompson, Alaska, for lipid studies. The birds were collected in 1960 during the postbreeding and autumnal premigratory period of late summer. Relevant data on life history, distribution, migration, and molt are presented. Extractions of body lip ...

An eight-month survey of the terrestrial vertebrate fauna of coastal Byron Shim produced records of 15 species of amphibians, 19 species of reptiles, 182 species of birds and 23 species of mammals. These results, together with records from other sources, show the area has a rich and diverse vertebrate fauna with only reptiles not well represented Vertebrate communities were characterized by specie ...

In birds arriving with body masses below °3.5 g, the initial period of mass gain was very slow. This slow gain was not explained by energy costs associated with territory establishment or learning to secure food, since it occurr ...

Abstract:: ... Pear psylla, Cacopsylla pyricola Förster (Homoptera: Psyllidae), was flown in the laboratory to test hypotheses suggested by field observations. Flight durations of the same insects flown on two different days were highly correlated, suggesting that there were biological differences among insects in flight tendencies. Flight durations were similar between summerform and winterform morphotypes. Fli ...

Abstract:: ... Large herbivores can both positively and negatively affect primary productivity and rates of nutrient cycling in different ecosystems. Positive effects of grazers in grasslands have been attributed to migratory behavior of the dominant ungulate species and soil fertility. We studied the effects of grazers on aboveground net primary productivity (ANPP) and N cycling on central Kenyan rangeland char ...

GBD results from exposure to gas supersaturated water created by discharge over dam spillways. Spill creates a downstream plume of water with high total dissolved gas supersaturation (TDGS) that may be positioned along either shore or mid-channel, depending on dam operations.

Abstract:: ... Concentrations of organochlorines (OCs), brominated flame retardants (BFRs) and mercury (Hg) were measured in eggs of six seabird species breeding in the Gulf of St. Lawrence, Canada. Stable nitrogen (δ15N) and carbon (δ13C) isotopes were used as ecological tracers to measure trophic level and connectivity with benthos, respectively. Concentrations, patterns as well as ecological tracers varied si ...

Abstract:: ... Biparental care is common in birds, with the allocation of effort being highly variable between the sexes. In most songbird species, the female typically provides the most care early in the breeding cycle with both parents providing care when provisioning young. Food provisioning should be directly related to offspring quality; however, the relative influence each parent has on offspring quality h ...

Hybridization with a wide-ranging marine congener should introduce genetic variation and reduce the effects of inbreeding depression and genetic drift. However, high levels of hybridization can cause demographic and gen ...

Abstract:: ... American black bears frequently abandon their home ranges in late summer and move to feeding areas to fatten themselves for hibernation. We examined seasonal movements of 206 radio-collared bears in north-central Minnesota during 1981â1990. We exploited the variability in this long-term data set to test tradeoffs for animals leaving their home range. Late summer movements were common for both se ...
