Global climate change impacts on coastal ecosystems in the Gulf of Mexico: Considerations for integrated coastal management Global climate change impacts on coastal ecosystems in the Gulf of Mexico: Considerations for integrated coastal management
Global climate change is important in considerations of integrated coastal management in the Gulf of Mexico. This is true for a number of reasons. Climate in the Gulf spans the range from tropical to the lower part of the temperate zone. Thus, as climate warms, the tropical temperate interface, which is currently mostly offshore in the Gulf of Mexico, will increasingly move over the...

Statewide summary for Louisiana: Chapter E in Emergent wetlands status and trends in the northern Gulf of Mexico: 1950-2010 Statewide summary for Louisiana: Chapter E in Emergent wetlands status and trends in the northern Gulf of Mexico: 1950-2010
Throughout the past century, emergent wetlands have been declining across the Gulf of Mexico. Emergent wetland ecosystems provide a variety of resources, including plant and wildlife habitat, commercial and recreational economic activity, and natural barriers against storms. As emergent wetland losses increase, so does the need for information on the causes and effects of this loss...

Mobile Bay Mobile Bay
Mobile Bay is the largest bay found in Alabama’s coastal area (Handley et al., 2007). It was named an Estuary of National Significance in 1995 under the U.S. Environmental Protection Agency’s (EPA) National Estuary Program (NEP), and its Comprehensive Conservation Management Plan was completed in 2002. Mobile Bay is 1,070 km2 (413 miles2) in area and 51 km (32 miles) long, making it the...

Environmental survey in the Tuul and Orkhon River basins of north-central Mongolia, 2010: Metals and other elements in streambed sediment and floodplain soil Environmental survey in the Tuul and Orkhon River basins of north-central Mongolia, 2010: Metals and other elements in streambed sediment and floodplain soil
Streambed sediment and subsurface floodplain soil were sampled for elemental analyses from 15 locations in river basins of north-central Mongolia during August 2010. Our primary objective was to conduct a reconnaissance-level assessment of potential inputs of toxicologically important metals and metalloids to Lake Baikal, Russia, that might originate from mining and urban activities...

Appendix D: Use of wave scenarios to assess potential submerged oil mat (SOM) formation along the coast of Florida and Alabama Appendix D: Use of wave scenarios to assess potential submerged oil mat (SOM) formation along the coast of Florida and Alabama
During the Deepwater Horizon oil spill, oil in the surf zone mixed with sediment in the surf zone to form heavier-than-water sediment oil agglomerates of various size, ranging from small (cm-scale) pieces (surface residual balls, SRBs) to large mats (100-m scale, surface residue mats, SR mats). Once SR mats formed in the nearshore or in the intertidal zone, they may have become buried by...

Generalized additive regression models of discharge and mean velocity associated with direct-runoff conditions in Texas: Utility of the U.S. Geological Survey discharge measurement database Generalized additive regression models of discharge and mean velocity associated with direct-runoff conditions in Texas: Utility of the U.S. Geological Survey discharge measurement database
A database containing more than 17,700 discharge values and ancillary hydraulic properties was assembled from summaries of discharge measurement records for 424 U.S. Geological Survey streamflow-gauging stations (stream gauges) in Texas. Each discharge exceeds the 90th-percentile daily mean streamflow as determined by period-of-record, stream-gauge-specific, flow-duration curves. Each...

Statewide summary for Alabama Statewide summary for Alabama
Alabama is over 132,000 km2 (51,000 miles2) in area, 483 km (300 miles) long, and 322 km (200 miles) wide (Copeland, 1968). Coastal Alabama comprises Mobile and Baldwin Counties and the surrounding State waters in the Gulf of Mexico (Figure 1; O’Neil and Mettee, 1982). It is part of both the East Gulf Coastal Plain section of the Coastal Plain province and the Mississippi-Alabama shelf...

Riverine habitat dynamics Riverine habitat dynamics
The physical habitat template is a fundamental influence on riverine ecosystem structure and function. Habitat dynamics refers to the variation in habitat through space and time as the result of varying discharge and varying geomorphology. Habitat dynamics can be assessed at spatial scales ranging from the grain (the smallest resolution at which an organism relates to its environment) to...

Nest success and reproductive ecology of the Texas Botteri’s Sparrow (Peucaea botterii texana) in exotic and native grasses Nest success and reproductive ecology of the Texas Botteri’s Sparrow (Peucaea botterii texana) in exotic and native grasses
Very little information is available for Peucaea botterii texana (Texas Botteri's Sparrow) and nothing is known about its nesting ecology, in part due to its cryptic behavior and nesting strategies. Our goal was to examine the nesting ecology of Texas Botteri's Sparrows and compare reproductive success between exotic and native grasslands. We searched for and monitored nests in 2004 and...

Conservation in an age of climate change Conservation in an age of climate change
Are you a gardener? Then you know that certain species and varieties of species grow best in certain growing zones related to climate. This growing zone concept also applies to species in natural ecosystems. One threat of climate change to wetland biodiversity is that some species may be losing the ability to track an appropriate season for flowering, seed production and growth...
