Native American impacts on fire regimes of the California coastal ranges Native American impacts on fire regimes of the California coastal ranges
Aim Native American burning impacts on California shrubland dominated landscapes are evaluated relative to the natural lightning fire potential for affecting landscape patterns.Location Focus was on the coastal ranges of central and southern California.Methods Potential patterns of Indian burning were evaluated based upon historical documents, ethnographic accounts, archaeological...

Lead burdens and behavioral impairments of the lined shore crab Pachygrapsus crassipes Lead burdens and behavioral impairments of the lined shore crab Pachygrapsus crassipes
Sublethal burdens of lead impair behaviors critical to survival in a variety of animals. In a test arena, I measured refuge-seeking behaviors of adult, male, lined shore crabs from lead-free and lead-contaminated sites. The body sizes of the test groups did not differ although the mean total body lead burdens differed by over 2,300%. A lead-contaminated environment does not appear to...

Interspecific interactions in trematode communities Interspecific interactions in trematode communities
This chapter reviews the behavioural ecology of trematodes, focusing on intramolluscular stages. Interspecific competitive interactions, their frequency, dominance hierarchies and resolutions are discussed. Strategies employed by larval trematode species to adapt to a hostile, competitive environment, how these adaptations shape larval trematode communities, and how altered trematode...

Clam density and scaup feeding behavior in San Pablo Bay, California Clam density and scaup feeding behavior in San Pablo Bay, California
San Pablo Bay, in northern San Francisco Bay, California, is an important wintering area for Greater (Aythya marila) and Lesser Scaup (A. affinis). We investigated variation in foraging behavior of scaup among five sites in San Pablo Bay, and whether such variation was related to densities of their main potential prey, the clams Potamocorbula amurensis and Macoma balthica. Time-activity...

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...
