Fairy shrimp (Anostraca) in the vernal pools of Eastern Washington
<p>Vernal pools are ephemeral wetlands that retain water annually from winter and spring precipitation and snowmelt but are dry the rest of the year. Though important habitats and sources of freshwater biodiversity, they are little accounted for in wetland conservation and restoration practices. …

Distributional Ecology of Vegetation in the Vernal Pools of the Santa Rosa Plateau, California
<p>Interpool distribution studies of 10 vernal pools on the Santa Rosa Plateau found area to be the best single predictor of species richness in each type of regression model evaluated. Area predicted most accurately in a mixed linear-curvilinear regression model (y = a + b log x). Area appeared to …

Spatial and Temporal variability of macroinvertyebrate communities in vernal pools on the Coastal Plain of Virginia
<p>Vernal pools are often defined as seasonal pools that typically are inundated beginning in the winter and then drying out completely in summer. Though evidence of spatial and temporal variability in the macroinvertebrate communities of vernal pools has been found in previous studies, it has not …

A comparative study of the vascular plants of three vernal pools in the San Joaquin Valley, California
… is known about the general nature and flora of vernal pools. Nevertheless, there is very limited information or actual documentation in the scientific literature. Vernal pools need to be studied more extensively. and they still offer unlimited opportunities for such research (Holland and Griggs …

The Distribution of ORCUTTIA CALIFORNICA (Poaceae) in the Vernal Pools of the Santa Rosa Plateau, Riverside County, California
… California, from April to September, 1976 in 11 vernal pools located on the Santa Rosa Plateau in Riverside County. To help determine why Orcutt grass occurs in only 6 of the 11 pools and more specifically why it only occurs in patches within a given pool, biweekly measurements of frequency, …

Depth Profiles and Soil Textures of the Vernal Pools of the Santa Rosa Plateau Preserve, Riverside County, California
… and topographic characteristics of the 13 vernal pools on the Santa Rosa Plateau Preserve, thus documenting the role soil texture plays in vernal pool formation.</p> <p>Several field and laboratory procedures were used to demonstrate that there is a higher percentage of clay present within …

Vernal Pool Mapping and Geomorphology in the Appalachian Mountains of Pennsylvania
Vernal pools are small seasonally-ponded wetlands that provide crucial habitat for amphibian reproduction and support trophic levels beyond their boundaries. The Ridge and Valley physiographic province in Pennsylvania is known to have vernal pools, but a regional inventory and geomorphology …

Physical and chemical correlates of Sacramento County vernal pool crustaceans
<p>Vernal pools are temporary aquatic habitats that can be home to dozens of 4 invertebrate species. Unfortunately, over 90 percent of California vernal pool habitat has been destroyed. To better understand the remaining habitat, this study focused on the species community structure of the pools, …

Evolutionary potential of a dispersal-restricted species in response to climate change
… species restricted to ephemeral wetlands called vernal pools in California to adapt to the projected patterns of climate change. Across <em>L. fremontii</em> distribution there is a latitudinal gradient in precipitation which, combined with reduced gene flow rates, might be driving adaptive …

Headwater stream network connectivity: biogeochemical consequences and carbon fate
… 4 streams, including dry reaches and adjacent vernal pools as well as flowing water. I found that emissions were highly variable over space and time; in particular, the presence of a vernal pool enhanced total carbon emissions from the stream corridor. Next, to quantify carbon cycling and …

Land development in Massachusetts: Its effect on the environment within Essex and Middlesex counties from 1990 to 2007
… spaces, and within 0-1000 feet of 600 certified vernal pools. In addition, several rare or imperiled species inhabiting these areas may have been adversely affected by land development through habitat loss, change, or fragmentation, and/or passage corridor disruptions. A GIS comparison of the …

RESOURCE SUBSIDIES ACROSS THE AQUATIC-TERRESTRIAL BOUNDARIES OF TEMPORARY PONDS
Aquatic habitats are closely linked to surrounding terrestrial environments via reciprocal subsidies. Much of the research on these subsidies has been focused on streams, while subsidies across aquatic-terrestrial boundaries of other aquatic systems, like temporary ponds, have received little …

Amphibian and plant communities of natural and constructed upland-embedded wetlands in the Daniel Boone National Forest
<p>Wetlands fulfill many vital ecological functions, including providing habitat for amphibians and plants. Some wetlands, known as upland-embedded wetlands (UEWs), are depressional wetlands surrounded completely by upland habitat. This wetland type has been constructed in many areas for …
