Clinical disease and laboratory abnormalities in free-ranging desert tortoises in California (1990-1995) Clinical disease and laboratory abnormalities in free-ranging desert tortoises in California (1990-1995)
Desert tortoise (Gopherus agassizii) populations have experienced precipitous declines resulting from the cumulative impact of habitat loss and human and disease-related mortality. Diagnosis of disease in live, free-ranging tortoises is facilitated by evaluation of clinical signs and laboratory test results but may be complicated by seasonal and environmental effects. The goals of this...

Factors influencing the variation in capture rates of shrews in southern California, USA Factors influencing the variation in capture rates of shrews in southern California, USA
We examined the temporal variation in capture rates of shrewsNotiosorex crawfordi (Coues, 1877) and Sorex ornatus (Merriam, 1895) in 20 sites representing fragmented and continuous habitats in southern California, USA. InN. crawfordi, the temporal variation was significantly correlated with the mean capture rates. Of the 6 landscape variables analyzed (size of the landscape, size of the...

Sea otter population declines in the Aleutian Archipelago Sea otter population declines in the Aleutian Archipelago
Sea otter (Enhydra lutris) populations were exploited to near extinction and began to recover after the cessation of commercial hunting in 1911. Remnant colonies of sea otters in the Aleutian archipelago were among the first to recover; they continued to increase through the 1980s but declined abruptly during the 1990s. We conducted an aerial survey of the Aleutian archipelago in 2000...

Relating species abundance distributions to species-area curves in two Mediterranean-type shrublands Relating species abundance distributions to species-area curves in two Mediterranean-type shrublands
Based on both theoretical and empirical studies there is evidence that different species abundance distributions underlie different species-area relationships. Here I show that Australian and Californian shrubland communities (at the scale from 1 to 1000 m2) exhibit different species-area relationships and different species abundance patterns. The species-area relationship in Australian...
