Abstract (from SpringerLink): Salt marsh-dependent species are vulnerable to impacts of sea-level rise (SLR). Site-specific differences in ecogeomorphic processes result in different SLR vulnerabilities. SLR impacts to Ridgway’s rail (Rallus obsoletus) of Southern California (SC) and San Francisco Bay (SF), U.S.A. could foreshadow SLR effects on other coastal endemic species. Salt marsh vulnerabilities to SLR were forecasted across 14 study sites using the Wetland Accretion Rate Model of Ecosystem Resilience, which accounts for changes in above and belowground marsh processes. Changes in suitable habitat for rail were projected with MaxEnt. Under a high (166 cm/100 yr) SLR scenario, current extent of suitable habitat...

Abstract (from http://link.springer.com/article/10.1007%2Fs12237-013-9725-x): We evaluated the biogeomorphic processes of a large (309 ha) tidal salt marsh and examined factors that influence its ability to keep pace with relative sea-level rise (SLR). Detailed elevation data from 1995 and 2008 were compared with digital elevation models (DEMs) to assess marsh surface elevation change during this time. Overall, 37 % (113 ha) of the marsh increased in elevation at a rate that exceeded SLR, whereas 63 % (196 ha) of the area did not keep pace with SLR. Of the total area, 55 % (169 ha) subsided during the study period, but subsidence varied spatially across the marsh surface. To determine which biogeomorphic and spatial...

This publication is a product from the project "Quantifying the Influence of Climate Change on Rocky Mountain Ungulates".
Abstract (from http://rspb.royalsocietypublishing.org/content/279/1732/1366.long): Altered species interactions are difficult to predict and yet may drive the response of ecological communities to climate change. We show that declining snowpack strengthens the impacts of a generalist herbivore, elk ( Cervus elaphus), on a common tree species. Thick snowpack substantially reduces elk visitation to sites; aspen ( Populus tremuloides) shoots in these areas experience lower browsing rates, higher survival and enhanced recruitment. Aspen inside herbivore exclosures have greatly increased recruitment, particularly at sites with thick snowpack. We suggest that long-term decreases in snowpack could help explain a widespread...

Tens of millions of migratory birds are dependent on wetland and riparian stopovers in arid and semiarid regions of North America. Global climate change would superimpose even greater stress on these ecosystems as indicated by climate change model predictions of higher temperatures and less precipitation in the southwestern United States. In partnership with the University of Arizona, the Nebraska Cooperative Research Unit, and the NASA Goddard Space Flight Center, USGS scientists have investigated (1) how climate change may alter the spacing and quality of critical wetland stopover habitats; (2) the sensitivities of migrating songbirds to loss of riparian forests due to climate change and water-use patterns; (3)...

This sea-level rise modeling program began in 2008 and is located at the U.S. Geological Survey, Western Ecological Research Center. The focus is to provide site level ground data and results that land managers, planners, and those concerned with the conservation of salt marsh habitats can use to make well-informed climate change adaptation decisions. The work is being done by the USGS San Francisco Bay Estuary Field Station and Dixon Field Station researchers. This interdisciplinary research program objectives include understand the risk to salt marsh endangered species using sea-level rise modeling, storm monitoring, and movement of animals during high water events. In addition, the ability for salt marsh habitats...
