Urban development can have multiple effects on mammalian carnivore communities. We conducted a meta-analysis of 7,929 photographs from 217 localities in 11 camera-trap studies across coastal southern California to describe habitat use and determine the urban proximity (distance edge) intensity (percentage area urbanized) occurrence species richness natural habitats close boundary. Coyotes (Canis latrans) bobcats (Lynx rufus) were distributed widely region. Domestic dogs lupus familiaris),...

Analysis of upwelling radiation (spectral reflectance) by remote sensing may provide valuable information on the nature and distribution primary producers, microphytobenthos, intertidal mudflat systems. Spatial temporal variation in spectral reflectance signal (400–900 nm) from surface an exposed was investigated relation to density vertical position microphytobenthos assemblages within sediment. measurements were obtained areas sediment colonized different (mainly mixtures diatoms...
Abstract Despite a large body of research concerning mercury (Hg) in birds, no single tissue has been used consistently to assess Hg exposure, and this hampered comparisons across studies. We evaluated the relationships concentrations among tissues four species waterbirds (American avocets [ Recurvirostra americana ], black‐necked stilts Himantopus mexicanus Caspian terns Hydroprogne caspia ; formerly Sterna Forster's forsteri ]) three life stages (prebreeding adults, breeding chicks) San...

Fire is a natural, dynamic process that integral to maintaining ecosystem function. The reintroduction of fire (e.g., prescribed fire, managed wildfire) critical management tool for protecting many frequent-fire forests against stand-replacing fires while restoring an essential ecological process.

Hydrocarbon-inducible cytochrome P4501A (CYP1A) expression was measured, as ethoxyresorufin-O-deethylase (EROD) activity, in livers of wintering harlequin ducks (Histrionicus histrionicus) captured areas Prince William Sound, Alaska, USA, oiled by the 1989 Exxon Valdez spill and birds from nearby unoiled areas, during 2005 to 2009 (up 20 years following spill). The present work repeated studies conducted 1998 that demonstrated using received oil, EROD activity elevated nearly a decade after...

Abstract Habitat disturbance from development, resource extraction, off‐road vehicle use, and energy development ranks highly among threats to desert systems worldwide. In the Mojave Desert, United States, these disturbances have promoted establishment of nonnative plants, so that native grasses forbs are now intermixed with, or been replaced by invasive, Mediterranean grasses. This shift in plant composition has altered food availability for Desert tortoises ( Gopherus agassizii ), a...

We tested whether extracting lipids reduced confounding variation in δ 13 C and 15 N values by analyzing paired lipid-extracted (LE) non-lipid-extracted (NLE) samples of bald eagle ( Haliaeetus leucocephalus (L., 1766)) whole eggs, muscle tissue from nine seabird one terrestrial bird species, four marine fish blue mussels Mytilus edulis L., 1758) collected the Aleutian archipelago, Alaska.

Abstract Gene transcription analysis for diagnosing or monitoring wildlife health requires the ability to distinguish pathophysiological change from natural variation. Herein, we describe methodology development of quantitative real‐time polymerase chain reaction (qPCR) assays measure differential transcript levels multiple immune function genes in sea otter ( Enhydra lutris ); otter‐specific qPCR primer sequences interest are defined. We establish a ‘reference’ range transcripts each gene...

Some coastal areas within this are heavily developed and highly impacted by humans, while other wild largely pristine. Determining relative importance food resource...
ABSTRACT The recovery of large carnivore species from over‐exploitation can have socioecological effects; thus, reliable estimates potential abundance and distribution represent a valuable tool for developing management objectives criteria. For sea otters ( Enhydra lutris ), as with many apex predators, equilibrium is not constant across space but rather varies function local habitat quality resource dynamics, thereby complicating the extrapolation carrying capacity K ) one location to...
Abstract We studied productivity, diets, and environmental contaminants in nesting bald eagles from the western Aleutian Islands, Alaska, USA, during summers of 1993 1994.
