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...

Comparison of post-fire seedling establishment between scrub communities in Mediterranean and non-Mediterranean climate ecosystems Comparison of post-fire seedling establishment between scrub communities in Mediterranean and non-Mediterranean climate ecosystems
1 Both fire regimes and the conditions under which fires occur vary widely. Abiotic conditions (such as climate) in combination with fire season, frequency and intensity could influence vegetation responses to fire. A variety of adaptations facilitate post-fire recruitment in mediterranean climate ecosystems, but responses of other communities are less well known. We evaluated the...

Stem demography and post-fire recruitment of a resprouting serotinous conifer Stem demography and post-fire 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...

Temporal and spatial variability in thalweg profiles of a gravel-bed river Temporal and spatial variability in thalweg profiles of a gravel-bed river
This study used successive longitudinal thalweg profiles in gravel-bed rivers to monitor changes in bed topography following floods and associated large sediment inputs. Variations in channel bed elevations, distributions of residual water depths, percentage of channel length occupied by riffles, and a spatial autocorrelation coefficient (Moran's I) were used to quantify changes in...

Reference conditions for giant sequoia forest restoration: structure, process, and precision Reference conditions for giant sequoia forest restoration: structure, process, and precision
National Park Service policy directs that more natural conditions be restored to giant sequoia groves, which have been altered by a century of fire exclusion. Efforts to find a reasonable and practical definition of “natural” have helped drive scientists and land managers to use past grove conditions as reference conditions for restoration. Extensive research aimed at determining...
