Increasing diversity in our profession Increasing diversity in our profession
The Wildlife Society's (TWS) Ethnic and Gender Diversity Committee (previously the Minority Affairs Committee) was established in 1998 and given several charges by TWS Council. This paper responds to our original charge to consider possi- ble actions and programs that TWS might undertake to increase minority participation in the wildlife profession and TWS (R.Anthony, 13 February 1998...

Spatial patterns in the abundance of the coastal horned lizard Spatial patterns in the abundance of the coastal horned lizard
Coastal horned lizards ( Phrynosoma coronatum) have undergone severe declines in southern California and are a candidate species for state and federal listing under the Endangered Species Act. Quantitative data on their habitat use, abundance, and distribution are lacking, however. We investigated the determinants of abundance for coastal horned lizards at multiple spatial scales...

Conflict of interest between a nematode and a trematode in an amphipod host: Test of the "sabotage" hypothesis Conflict of interest between a nematode and a trematode in an amphipod host: Test of the "sabotage" hypothesis
Microphallus papillorobustus is a manipulative trematode that induces strong behavioural alterations in the gamaridean amphipod Gammarus insensibilis, making the amphipod more vulnerable to predation by aquatic birds (definitive hosts). Conversely, the sympatric nematodeGammarinema gammari uses Gammarus insensibilis as a habitat and a source of nutrition. We investigated the conflict of...

Polychlorinated biphenyls and toxaphene in Pacific tree frog tadpoles (Hyla regilla) from the California Sierra Nevada, USA Polychlorinated biphenyls and toxaphene in Pacific tree frog tadpoles (Hyla regilla) from the California Sierra Nevada, USA
Pacific tree frog (Hyla regilla) tadpoles were collected throughout the Sierra Nevada mountain range, California, USA, in 1996 and 1997 and analyzed for the presence of polychlorinated biphenyls (PCBs) and toxaphene. Whole-tadpole Σ PCB levels ranged from 244 ng/g (wet wt) at lower elevations on the western slope to 1.6 ng/g high on the eastern slope, whereas Σ toxaphene levels ranged...

Western Sandpipers (Calidris mauri) during the non-breeding season: Spatial segregation on a hemispheric scale Western Sandpipers (Calidris mauri) during the non-breeding season: Spatial segregation on a hemispheric scale
The nonbreeding distribution of Western Sandpipers (Calidris mauri) was documented using 19 data sets from 13 sites along the Pacific and Atlantic coasts of the Americas. Western Sandpipers showed latitudinal segregation with regard to sex and age. Females wintered farther south than males. A “U” shaped pattern was found with respect to age, with juveniles occurring at higher proportions...

Avian furcula morphology may indicate relationships of flight requirements among birds Avian furcula morphology may indicate relationships of flight requirements among birds
This study examined furcula (wishbone) shape relative to flight requirements. The furculae from 53 museum specimens in eight orders were measured: 1) three-dimensional shape (SR) as indicated by the ratio of the direct distance between the synostosis interclavicularis and the ligamentous attachment of one of its clavicles to the actual length of the clavicle between those same two points...
