Mercury correlations among six tissues for four waterbird species breeding in San Francisco Bay, California, USA.
TLDR
It is suggested that blood is an excellent, nonlethal predictor of HG concentrations in internal tissues but that feathers are relatively poor indicators of Hg concentrations inInternal tissues. Expand
Avian mercury exposure and toxicological risk across western North America: A synthesis.
TLDR
Results indicate that mercury contamination of birds is prevalent in many areas throughout western North America, and large-scale ecological attributes are important factors influencing bird mercury concentrations. Expand
Exploring individual quality: Basal metabolic rate and reproductive performance in storm-petrels
TLDR
The results provide evidence that intraspecific variation in reproductive performance is related to BMR and suggest that BMR may influence individual quality in males, and support the compensation hypothesis. Expand
Tidal Influence on Spatial Dynamics of Leopard Sharks, Triakis semifasciata, in Tomales Bay, California
TLDR
Leopard sharks showed strong movement direction patterns with tide, and moved significantly towards the inner bay, apparently to exploit the extensive inner bay muddy littoral zones' food resources. Expand
Effects of radiotransmitters on the reproductive performance of Cassin’s auklets
TLDR
Caution in using telemetry to evaluate the reproductive performance of alcids is suggested, but marking only females may minimize adverse effects. Expand
Effects of investigator disturbance on hatching success and nest-site fidelity in a long-lived seabird, Leach's storm-petrel
TLDR
It is demonstrated that both weekly and daily investigator disturbance during incubation greatly reduced the hatching success and subsequent nest-site fidelity of naive Leach's storm-petrels. Expand
Cues for investment: nest desertion in response to partial clutch depredation in dabbling ducks
TLDR
The results indicate that several factors influence clutch value and that ducks are able to use multiple cues to finely adjust their level of parental care following partial clutch depredation. Expand
Mercury demethylation in waterbird livers: dose-response thresholds and differences among species.
TLDR
The findings indicate that waterbirds demethylate mercury in their livers if exposure exceeds a threshold value and suggest that taxonomic differences in demethylation ability may be an important factor in evaluating species-specific risk to MeHg exposure. Expand
Cross-seasonal patterns of avian influenza virus in breeding and wintering migratory birds: a flyway perspective.
TLDR
This study characterized spatio-temporal infection patterns in 10,389 waterfowl at two important locations within the Pacific Flyway and shed light on how the dynamics of AIV infection of wild bird populations can vary between the two ends of a migratory flyway. Expand
Sexing Forster’s Terns using Morphometric Measurements
TLDR
It is indicated that Forster’s Terns can be accurately sexed in the field using only 2 morphological measurements, and sexual size dimorphism was greatest with retrix R6 length, followed by culmen width, and culmen depth. Expand
