Parastichopus parvimensis and P. californicus, two ecologicallysimilar species of sea cucumber, are the only sea cucumber fisheries in California.1 Aside from the economic importance that this distinction affords them, the two also play an important ecological role as subtidal, benthic detritivores.1, 2 Though some ecological distinctions between the two species exist – P. californicus, notably...

The California myotis, Myotis californicus, and western small-footed myotis, Myotis ciliolabrum, are 2 morphologically similar bats which have had a complex taxonomic history due to intraspecific geographic variation across their sympatric distribution in western North America. Despite several published differences, field identification remains problematic in the southwestern United States. Mit...

We report here that (4R,9Z)-hexadec-9-en-4-olide [(R)-desmolactone] is a sex attractant or sex pheromone for multiple species and subspecies in the cerambycid genus Desmocerus. This compound was previously identified as a female-produced sex attractant pheromone of Desmocerus californicus californicus. Headspace volatiles from female Desmocerus aureipennis aureipennis contained (R)-desmolactone...

A new species of phytoseiid mite of the genus Neoseiulus (Acari, Phytoseiidae) found in Svalbard is described and illustrated. Redescriptions, drawings, measurements, and diagnosis of two related species, N. magnanalis (Thor) and N. ellesmerei (Chant & Hansell) are given. A neotype is designated for N. magnanalis.

Giant red sea cucumbers, Parastichopus californicus, are commercially harvested in the U.S. Pacific Northwest; however, the nutritional and chemical properties of its edible muscle bands and body wall have not been fully elucidated. In particular are the fatty acid profiles of P. californicus tissues, which have not been documented. Sea cucumbers were delivered live and muscle bands and body wa...

Western flower thrips (WFT), Frankliniella occidentalis (Pergande), is an important pest of vegetable crops worldwide and has developed resistance to many insecticides. The predatory mites Neoseiulus (=Amblyseius) cucumeris (Oudemans), the entomopathogenic fungus Metarhizium anisopliae (Metsch.), and an insecticide (imidacloprid) were tested for their efficacy to reduce WFT population density a...

Intestinal contents from 12 scaled quail (Callipepla squamata), 10 bobwhite quail (Colinus virginianus), 20 harlequin quail (Cyrtonyx montezumae), 35 California quail (Lophortyx californicus), 15 Gambel's quail (Lophortyx gambelii), and 29 mountain quail (Oreortyx pictus) were examined for coccidian oocysts. Only 18 (14.9%) of 121 birds had coccidian oocysts in their feces at the time of collec...
