Subject:
Decapoda; beaches; crabs; females; habitats; males; sand; summer; winter; Atlantic Ocean; Gulf of Mexico; Texas
Abstract:
... Albuneid sand crabs are found in sandy beaches around the world, but little is known about the basic biology of any species in the family. We sampled sand crabs, Lepidopa benedicti, for 2 years at South Padre Island, Texas, at two locations: one developed site near the town, where recreational use is high and one undeveloped site away from the town, where recreational use is lower. We hypothesized ...

Abstract:
... The Rio Grande and its tributaries in the Trans-Pecos region of Texas have been impacted by a variety of anthropogenic activities such as dewatering and the introduction of nonnative species. These environmental manipulations have negatively affected the native fishes leading to extirpations and declining populations throughout the region. Campostoma ornatum and Notropis chihuahua inhabit tributar ...

In this study, we investigated oysters, Crassostrea virginica, from Laguna Madre in South Texas, where a 45-yr old study recorded metacercarial infections of the echinostomatid trematode, Acanthoparyphium spinulosum, an Asian relative of which, Acanthoparyphium tyosenense, has been associated with human infections via the ingestion of raw mollusks. In an effort to examine the base-line infection p ...

Abstract:
... Active growth faults contribute to the subsidence of deltaic basins around the world and can significantly augment local rates of relative sea level rise, which can inundate and drown wetlands. Little information exists on the temporal frequency and spatial magnitude of motion along these faults. Our objective was to quantify fault activity and displacement at multiple time scales in a salt marsh ...

Abstract:
... The aerial electrostatic spraying system patented by the USDA-ARS is a unique aerial application system which inductively charges spray particles for the purpose of increasing deposition and efficacy. While this system has many potential benefits, very little is known about how changes in airspeed or nozzle orifice size affect the spray droplet spectrum of charged spray. This study quantified thes ...

Abstract:
... In-vehicle air quality (IVAQ) can be a major health concern due to factors such as urban sprawl and increased commuting time spent by individuals in vehicles. Few studies, particularly in the U.S., have considered in-vehicle toxic air contaminants, and none to date collected/analyzed field data in multiple communities across multiple climate zones. This study presents analyses of field data collec ...

Although several Alligator Gars used over 100 km of the river, 83% of the tagged fish had linear home ranges less than 60 km during the 22 months of study. As a result, home ranges of fish that were tagged in different parts of the stu ...

Abstract:
... The geomorphological impact of an extreme storm on a barrier island tends to be modeled using a single cross-shore transect and dependent only on the elevation of the storm surge relative to the height of the dune. The foredune line, however, is rarely uniform and can exhibit considerable variation in height and width alongshore at a range of length scales. The purpose of this modeling study is to ...

BACKGROUND: The apicomplexan hemoprotozoan parasite Theileria equi is one of the etiologic agents causing equine piroplasmosis, a disease of equines that is endemic throughout large parts of the world. Before 2009 the United States had been considered to be free of this parasite. Occasional cases had occurred but there was no evidence for endemic vector-borne transmission in the U.S. until a 2009 ...
