Trematodes in snails near raccoon latrines suggest a final host role for this mammal in California Salt Marshes Trematodes in snails near raccoon latrines suggest a final host role for this mammal in California Salt Marshes
Of the 18 trematode species that use the horn snail, Cerithidea californica, as a first intermediate host, 6 have the potential to use raccoons as a final host. The presence of raccoon latrines in Carpinteria Salt Marsh, California, allowed us to investigate associations between raccoons and trematodes in snails. Two trematode species, Probolocoryphe uca and Stictodora hancocki, occurred...

Fire history of the San Francisco East Bay region and implications for landscape patterns Fire history of the San Francisco East Bay region and implications for landscape patterns
The San Francisco East Bay landscape is a rich mosaic of grasslands, shrublands and woodlands that is experiencing losses of grassland due to colonization by shrubs and succession towards woodland associations. The instability of these grasslands is apparently due to their disturbance-dependent nature coupled with 20th century changes in fire and grazing activity. This study uses fire...

Fire and the Miocene expansion of C4 grasslands Fire and the Miocene expansion of C4 grasslands
C4 photosynthesis had a mid-Tertiary origin that was tied to declining atmospheric CO2, but C4-dominated grasslands did not appear until late Tertiary. According to the ‘CO2-threshold’ model, these C4 grasslands owe their origin to a further late Miocene decline in CO2 that gave C4 grasses a photosynthetic advantage. This model is most appropriate for explaining replacement of C3...

Puncture-ejection of own egg by Least Bell's Vireo and potential implications for anti-parasitism defense Puncture-ejection of own egg by Least Bell's Vireo and potential implications for anti-parasitism defense
A simple, papillary cystic adenocarcinoma of the mammary gland with metastases to the internal iliac and mesenteric lymph nodes, liver, and spleen was observed in a 12 to 13 year old female black-footed ferret (Mustela nigripes). Histologically, the tumor was aggressive, and lymphatic invasion was found. Attempts at virus isolation were negative. Other findings were bilateral infarcts in...
