Postflood persistence and recolonization of endangered tidewater goby populations Postflood persistence and recolonization of endangered tidewater goby populations
Before-and-after surveys at several southern California sites indicated that populations of endangered tidewater goby Eucyclogobius newberryi persisted through heavy flooding in 1995. This was contrary to our expectations that flooding might have led to extirpation in some smaller wetlands. There was also no significant change in tidewater goby density before and after the flooding...

Habitat invasibility and dominance by alien annual plants in the western Mojave Desert Habitat invasibility and dominance by alien annual plants in the western Mojave Desert
Patterns of habitat invasibility and alien dominance, respectively measured as species richness and biomass of alien annual plants, were evaluated in association with four habitat factors at the Desert Tortoise Research Natural Area (DTNA) in the western Mojave Desert, USA. Habitat factors varied in levels of disturbance outside (high) and inside (low) the DTNA, and in levels of soil...

Association of seasonal reproductive patterns with changing food availability in an equatorial carnivore, the spotted hyaena (Crocuta crocuta) Association of seasonal reproductive patterns with changing food availability in an equatorial carnivore, the spotted hyaena (Crocuta crocuta)
Reproductive seasonalitywas examined inan equatorial populationof free-living spotted hyaenas (Crocuta crocuta) inKenya. The study population was observed continuously for 10 years, duringwhich time the dates of all births, conceptions, weanings,andcubdeathswererecorded.Local preyabundancewasestimatedtwoto four timespermonth, andrainfallwas recordeddailythroughout thestudyperiod

Stem demography and postfire recruitment of a resprouting serotinous conifer Stem demography and postfire recruitment of a resprouting serotinous conifer
The contribution of resprouts and seedling recruitment to post-fire regeneration of the South African fynbos conifer Widdringtonia nodiflora was compared eight months after wildfires in 1990. Stems on all trees were killed by fire but resprouting success was > 90 % at all but one site. A demographic study of burned skeletons revealed that prior to these fires, nearly all plants were...

Reexamining fire suppression impacts on brushland fire regimes Reexamining fire suppression impacts on brushland fire regimes
California shrubland wildfires are increasingly destructive, and it is widely held that the problem has been intensified by fire suppression, leading to larger, more intense wildfires. However, analysis of the California Statewide Fire History Database shows that, since 1910, fire frequency and area burned have not declined, and fire size has not increased. Fire rotation intervals have...

Enhancement of PAHs in estuarine invertebrates by surface runoff at a decommissioned military fuel depot Enhancement of PAHs in estuarine invertebrates by surface runoff at a decommissioned military fuel depot
Accumulation of polycyclic aromatic hydrocarbons (PAHs) was determined in blue mussels (Mytilus spp.) and shore crabs (Hemigrapsus sp.) at a recently closed military fuel depot in central San Francisco Bay, California. In April 1996, during a period of above average precipitation, specimens were collected at the depot, near the depot, and at sites 10 and 20 km south of the depot. Four...
