Isotopic niche plasticity of American alligators within the southern Everglades Isotopic niche plasticity of American alligators within the southern Everglades
Hydrologic alterations within the Everglades have degraded American alligator (Alligator mississippiensis) habitat, reduced prey base, and increased physiological stress. Alligator body condition declined across many management areas from 2000 through 2014, prompting us to investigate the relationship between their intraspecific isotopic niche dynamics and body condition. Alligators...

Anthropogenic activities have greatly altered mangroves over the last hundred years Anthropogenic activities have greatly altered mangroves over the last hundred years
Mangroves not only provide ecosystem and cultural services but also contribute to the mitigation of global warming. Mangrove dynamics and their environmental responses as re-constructed from the past can inform current mangrove conservation and restoration. However, our understanding of mangrove dynamics over the past century and the impact of human activities on these ecosystems remains...

Network of networks: Time series clustering of AmeriFlux sites Network of networks: Time series clustering of AmeriFlux sites
Environmental observation networks, such as AmeriFlux, are foundational for monitoring ecosystem response to climate change, management practices, and natural disturbances; however, their effectiveness depends on their representativeness for the regions or continents. We proposed an empirical, time series approach to quantify the similarity of ecosystem fluxes across AmeriFlux sites. We...

Multiscale framework for assessing land cover change on barrier islands from extreme storms and restoration Multiscale framework for assessing land cover change on barrier islands from extreme storms and restoration
Often found along the estuarine-marine interface, barrier islands and mainland coastal zones are shaped by tides, currents, extreme storms, and relative sea-level rise. These systems provide ecosystem services such as storm surge and wave attenuation, erosion protection to inland areas, habitat for fish and wildlife, recreation, and tourism. Given the importance of these ecosystems...

Diamondback terrapin resource use in a seagrass-dominated coastal bay varies by life stage Diamondback terrapin resource use in a seagrass-dominated coastal bay varies by life stage
Diamondback terrapins, hereafter referred to as terrapins, are the only estuarine turtle species native to North America. However, terrapins are also occasionally found in marine habitats, such as seagrass beds, and yet little is known about how they use those marine habitats. We sampled epidermis from terrapins (Malaclemys terrapin macrospilota) inhabiting a seagrass-dominated coastal...

Human perturbations to mercury in global rivers Human perturbations to mercury in global rivers
Mercury compounds are potent neurotoxins that pose threats to human health, primarily through fish consumption. Rivers, critical for drinking water and food supply, have seen rapid increases in mercury concentrations and export to coastal margins since the Industrial Revolution (~1850). However, patterns of these changes remain understudied, limiting assessments of environmental policies...

Elevated CO2 enables brackish marsh transgression into freshwater forested wetlands while stimulating CH4 emissions Elevated CO2 enables brackish marsh transgression into freshwater forested wetlands while stimulating CH4 emissions
Wetlands are significant carbon (C) sinks and are expected to promote greater C assimilation as atmospheric CO2 concentrations rise. However, the fate of C with environmental change along fresh-to-oligohaline wetland transitions is not well understood. We established an ex-situ mesocosm experiment to mimic future elevated atmospheric CO2 concentrations (eCO2, 720 ppm) versus current (380...

Shotgun sequencing of airborne eDNA achieves rapid assessment of whole biomes, population genetics and genomic variation Shotgun sequencing of airborne eDNA achieves rapid assessment of whole biomes, population genetics and genomic variation
Biodiversity and its associated genetic diversity are being lost at an unprecedented rate. Simultaneously, the distributions of flora, fauna, fungi, microbes and pathogens are rapidly changing. Novel technology can help to capture and record genetic diversity before it is lost and to measure population shifts and pathogen distributions. Here we report the rapid application of shotgun...

New insights reveal a temporally distinct two-stock genetic structure for Suwannee River Gulf sturgeon New insights reveal a temporally distinct two-stock genetic structure for Suwannee River Gulf sturgeon
Understanding population genetic structure and patterns of gene flow is important for effective decision making and the preservation of genetic diversity, especially when managing protected species. Historically, Gulf sturgeon have been managed by river system, with early evidence supporting spatially distinct genetic structure across 7 natal populations. However, an increasing number of...

Foraging of wading birds on a patchy landscape: Simulating effects of social information, interference competition, and patch selection on prey intake and individual distribution Foraging of wading birds on a patchy landscape: Simulating effects of social information, interference competition, and patch selection on prey intake and individual distribution
Foragers on patchy landscapes must acquire sufficient resources despite uncertainty in the location and amount of the resources. Optimal Foraging Theory posits that foragers deal with this uncertainty by using strategies that optimize resource intake within foraging periods. For species such as wading birds, this optimization is closely linked to their survival and reproductive success

Interpreting a sudden population decline in a long-lived species (Malaclemys terrapin rhizophorarum) Interpreting a sudden population decline in a long-lived species (Malaclemys terrapin rhizophorarum)
Long-term ecological studies are critical for providing insight into population dynamics and detecting population declines, particularly for species of conservation concern. However, spatiotemporal variation and logistical challenges make the identification of sudden population declines difficult. We conducted an in-water capture-mark-recapture study of mangrove diamond-backed terrapins
