Gulf Coast vulnerability assessment: Mangrove, tidal emergent marsh, barrier islands and oyster reef Gulf Coast vulnerability assessment: Mangrove, tidal emergent marsh, barrier islands and oyster reef
Climate, sea level rise, and urbanization are undergoing unprecedented levels of combined change and are expected to have large effects on natural resources—particularly along the Gulf of Mexico coastline (Gulf Coast). Management decisions to address these effects (i.e., adaptation) require an understanding of the relative vulnerability of various resources to these stressors. To meet...

Prevalence of Batrachochytrium dendrobatidis and B. salamandrivorans in the Gulf Coast Waterdog, Necturus beyeri, from Southeast Louisiana, USA Prevalence of Batrachochytrium dendrobatidis and B. salamandrivorans in the Gulf Coast Waterdog, Necturus beyeri, from Southeast Louisiana, USA
The globally widespread amphibian fungal pathogen Batrachochytrium dendrobatidis (Bd) has been linked to amphibian declines worldwide (Lips et al. 2006; Skerratt et al. 2007). In Louisiana, USA, Bd has been found in several amphibian species (Chatfield et al. 2012; Rothermel et al. 2008), but to our knowledge no population-level die-offs have been observed. Published literature on Bd...

Global hotspots and correlates of alien species richness across taxonomic groups Global hotspots and correlates of alien species richness across taxonomic groups
Human-mediated transport beyond biogeographic barriers has led to the introduction and establishment of alien species in new regions worldwide. However, we lack a global picture of established alien species richness for multiple taxonomic groups. Here, we assess global patterns and potential drivers of established alien species richness across eight taxonomic groups (amphibians, ants...

Repeated drought alters resistance of seed bank regeneration in baldcypress swamps of North America Repeated drought alters resistance of seed bank regeneration in baldcypress swamps of North America
Recurring drying and wetting events are likely to increase in frequency and intensity in predicted future droughts in the central USA and alter the regeneration potential of species. We explored the resistance of seed banks to successive droughts in 53 sites across the nine locations in baldcypress swamps in the southeastern USA. Along the Mississippi River Alluvial Valley and northern...

Quantifying drivers of wild pig movement across multiple spatial and temporal scales Quantifying drivers of wild pig movement across multiple spatial and temporal scales
Background The movement behavior of an animal is determined by extrinsic and intrinsic factors that operate at multiple spatio-temporal scales, yet much of our knowledge of animal movement comes from studies that examine only one or two scales concurrently. Understanding the drivers of animal movement across multiple scales is crucial for understanding the fundamentals of movement...

Response of bird community structure to habitat management in piñon-juniper woodland-sagebrush ecotones Response of bird community structure to habitat management in piñon-juniper woodland-sagebrush ecotones
Piñon (Pinus spp.) and juniper (Juniperus spp.) woodlands have been expanding their range across the intermountain western United States into landscapes dominated by sagebrush (Artemisia spp.) shrublands. Management actions using prescribed fire and mechanical cutting to reduce woodland cover and control expansion provided opportunities to understand how environmental structure and...

Performance measures for a Mississippi River reintroduction into the forested wetlands of Maurepas Swamp Performance measures for a Mississippi River reintroduction into the forested wetlands of Maurepas Swamp
The use of freshwater diversions (river reintroductions) from the Mississippi River as a restoration tool to rehabilitate Louisiana coastal wetlands has been promoted widely since the first such diversion at Caernarvon became operational in the early 1990s. To date, aside from the Bonnet Carré Spillway (which is designed and operated for flood control), there are only four operational...

Mangrove species' responses to winter air temperature extremes in China Mangrove species' responses to winter air temperature extremes in China
The global distribution and diversity of mangrove forests is greatly influenced by the frequency and intensity of winter air temperature extremes. However, our understanding of how different mangrove species respond to winter temperature extremes has been lacking because extreme freezing and chilling events are, by definition, relatively uncommon and also difficult to replicate...

Songbirds are resilient to hurricane disturbed habitats during spring migration Songbirds are resilient to hurricane disturbed habitats during spring migration
The Gulf of Mexico is a conspicuous feature of the Neotropical–Nearctic bird migration system. Traveling long distances across ecological barriers comes with considerable risks, and mortality associated with intercontinental migration may be substantial, including that caused by storms or other adverse weather events. However, little, if anything, is known about how migratory birds...

A new mechanistic approach for the further development of a population with established size bimodality A new mechanistic approach for the further development of a population with established size bimodality
Usually, the origin of a within-cohort bimodal size distribution is assumed to be caused by initial size differences or by one discrete period of accelerated growth for one part of the population. The aim of this study was to determine if more continuous pathways exist allowing shifts from the small to the large fraction within a bimodal age-cohort. Therefore, a Eurasian perch population...

Cyanobacteria of the 2016 Lake Okeechobee and Okeechobee Waterway harmful algal bloom Cyanobacteria of the 2016 Lake Okeechobee and Okeechobee Waterway harmful algal bloom
The Lake Okeechobee and the Okeechobee Waterway (Lake Okeechobee, the St. Lucie Canal and River, and the Caloosahatchee River) experienced an extensive harmful algal bloom within Lake Okeechobee, the St. Lucie Canal and River and the Caloosahatchee River in 2016. In addition to the very visible bloom of the cyanobacterium Microcystis aeruginosa, several other cyanobacteria were present...

Delineation of marsh types and marsh-type change in coastal Louisiana for 2007 and 2013 Delineation of marsh types and marsh-type change in coastal Louisiana for 2007 and 2013
The Bureau of Ocean Energy Management researchers often require detailed information regarding emergent marsh vegetation types (such as fresh, intermediate, brackish, and saline) for modeling habitat capacities and mitigation. In response, the U.S. Geological Survey in cooperation with the Bureau of Ocean Energy Management produced a detailed change classification of emergent marsh...
