Pollination is fundamental to healthy ecosystems, and global pollination services have been valued at over $200 billion annually. However, landscape fragmentation, urban growth, ecosystem degradation adversely influence insect pollinator biodiversity. Efforts mitigate these factors must be enhanced in order establish increase populations. As such, a better understanding of the landscapes that m...

The 2010 Deepwater Horizon oil spill, the largest ever accidental release of oil into marine waters, affected hundreds of miles of US northern Gulf of Mexico coastline that is important habitat for migratory shorebirds. Shorebirds are particularly susceptible to oil contamination because of their subsurface probe-foraging behavior and reliance on intertidal habitat. More than one million migrat...

A partial fish skull with a nearly complete rostrum, a cup-shaped sclerotic hone, and cycloid scales (UCMP 123170) from the Yaquina Formation (late Oligocene, Oregon) is described and identified as tAglyptorhynchus maxillaris, sp. nov. Unusual features of the rostrum include a fused premaxillary segment with a low dorsal keel, and a maxilla with both a flat flange on its postero-ventral margin ...

Bycatch studies have largely ignored population level effects on fish species of little commercial interest. Here we analyze bycatch of the lined seahorse (Hippocampus erectus) in the bait-shrimp trawl fishery in Hernando Beach, Florida, providing the first fisheries data for this species. Based on catch per unit of effort (CPUE), size, sex, and reproductive status of trawled H. erectus, 1) app...

From 1998 to 2008, 68 adult female loggerhead sea turtles (Caretta caretta) were instrumented with platform transmitter terminals at nesting beaches in Georgia, North Carolina (NC) and South Carolina (SC) on the East Coast of the United States of America (30 480N, 81 280W to 33 510N, 77 590W). The majority of post-nesting loggerheads (N = 42, 62 %) migrated to foraging habitats in the Mid-Atlan...

The variability of mesoscale circulation structures in the Gulf of Mexico (GOM) was examined using satellite altimeter data collected between 1992 and 2008, and linkages between ocean circulation and the spatial distribution of larval fish were assessed. The abundance and distribution of the larvae of 5 pelagic fish taxa (Auxis spp., Euthynnus alleteratus, Thunnus thynnus, other Thunnus spp., a...

Eastern Oysters are found along the eastern coast of North America, from Canada to Mexico, including the Gulf of Mexico and some Caribbean islands. They grow very quickly, reach sexual maturity within several months, and can release tens of millions of eggs each year. Population sizes of Eastern Oysters vary by region, being severely depleted in some areas such as the Chesapeake Bay and healthi...

the evaluation of ecological characteristics of wildlife species has fundamental role in species management, because taking a decision for proper method of management is only possible by characterizing of ecological requirements of a species. in this study, suitable habitat of middle spotted woodpecker was investigated in golestan national park. presence and absence of birds and environmental v...

This study evaluated the relationship between abiotic flow characteristics and habitat quality. Habitat quality was assessed using Instream Flow Incremental Methodology (IFIM), which uses bioindication. Brown trout selected as a bioindicator because of its sensitivity to morphological changes occurrence in sufficient reference reaches. The correlation stream area-weighted suitability (AWS), rep...
