Structured Decision Making for Management of Warm-Water Habitat of Manatees

Manatees are tropical to subtropical in distribution and, with few exceptions, Florida is the northern limit of their natural winter range.  The availability of warm-water habitat during winter is critical for the future persistence of the population in Florida.

Groundwater Monitoring Program for the Brunswick-Glynn County Area, Georgia

In the Brunswick, Georgia area, saltwater has contaminated the Upper Floridan aquifer for nearly 50 years. Saltwater contamination has constrained further development of the Upper Floridan aquifer in the Brunswick area, which has stimulated interest in the development of alternative sources of water supply, primarily from the shallower surficial and Brunswick aquifer systems.

Geohydrology and Effects of Climate and Pumpage Change on Water Resources of the Aucilla–Suwannee–Ochlockonee River Basin, South-Central Georgia and Adjacent Areas of Florida, Progress and Significant Results, 2006—2007

Episodic droughts and increased pumpage since the mid-1970s have caused unprecedented ground-water level decline in the Upper Floridan aquifer in much of the roughly 8,000 square-mile Aucilla-Suwannee-Ochlockonee (ASO) River Basin.

State environmental agencies are charged with the protection of groundwater and surface-water systems from water-quality degradation. Although the point-source discharge of wastes to surface waters is allowed up to permitted levels, contaminant releases from non-point sources, such as the discharge of contaminated groundwater, is not regulated. A common cause of groundwater contamination is...

Water Use Trends in Alabama

Since 1950 when the U.S. Geological Survey (USGS) first conducted water-use compilations, important changes in water use have occurred in Alabama. The early part of the history (1950 to 1980) showed a steady increase in water use. During this time, the expectation was that, as the population increased, so would water use. Contrary to this expectation, reported water withdrawals declined in...

Frequency of extreme freeze events controls the distribution and structure of black mangroves (Avicennia germinans) near their northern range limit in coastal Louisiana

AimClimate change is expected to result in the tropicalization of coastal wetlands in the northern Gulf of Mexico, as warming winters allow tropical mangrove forests to expand their distribution poleward at the expense of temperate salt marshes. Data limitations near mangrove range limits have hindered understanding of the effects of winter...

Divergent biotic and abiotic filtering of root endosphere and rhizosphere soil fungal communities along ecological gradients

Plant roots assemble two distinct microbial compartments: the rhizosphere (microbes in soil surrounding roots) and the endosphere (microbes within roots). Our knowledge of fungal community assembly in these compartments is limited, especially in wetlands. We tested the hypothesis that biotic factors would have direct effects on rhizosphere and...

Proposed species extinction target fails to capture the diversity in biodiversity

We believe the 20 species extinction metric is a retrograde proposal, which does not adequately consider the lessons learnt from the 2020 Aichi Biodiversity Targets. Whilst having a single simple overarching target is appealing, we believe a positively-framed target will garner support, rather than one that aims to, at best, limit negative impacts...
