Diving and foraging behaviors Diving and foraging behaviors
Manatees and dugongs live in tropical and semi-tropical regions around the world. Their preferred habitats are seagrass beds, rivers, lakes, and estuaries. Manatees live in both freshwater and marine systems although habitat preferences vary across the three species, while the dugong is entirely marine. Sirenians are shallow water divers, and their dive durations are short compared to...

Genetic and morphological characterization of the freshwater mussel clubshell species complex (Pleurobema clava and Pleurobema oviforme) to inform conservation planning Genetic and morphological characterization of the freshwater mussel clubshell species complex (Pleurobema clava and Pleurobema oviforme) to inform conservation planning
The shell morphologies of the freshwater mussel species Pleurobema clava (federally endangered) and Pleurobema oviforme (species of concern) are similar, causing considerable taxonomic confusion between the two species over the last 100 years. While P. clava was historically widespread throughout the Ohio River basin and tributaries to the lower Laurentian Great Lakes, P. oviforme was...

Improved wetland soil organic carbon stocks of the conterminous U.S. through data harmonization Improved wetland soil organic carbon stocks of the conterminous U.S. through data harmonization
Wetland soil stocks are important global repositories of carbon (C) but are difficult to quantify and model due to varying sampling protocols, and geomorphic/spatio-temporal discontinuity. Merging scales of soil-survey spatial extents with wetland-specific point-based data offers an explicit, empirical and updatable improvement for regional and continental scale soil C stock assessments...

Council monitoring and assessment program (CMAP): Common monitoring program attributes and methodologies for the Gulf of Mexico Region Council monitoring and assessment program (CMAP): Common monitoring program attributes and methodologies for the Gulf of Mexico Region
Executive Summary Under the Resources and Ecosystem Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act of 2012 (RESTORE Act), the Gulf Coast Ecosystem Restoration Council (RESTORE Council or Council) is required to report on the progress of funded projects and programs. Systematic monitoring of restoration at the project-specific and programmatic...

Biology characterization breakout report Biology characterization breakout report
The primary goal of the biology characterization breakout group was to identify the strategies, tools, data priorities, and key partnerships needed to conduct baseline biological characterizations of deep-sea benthic environments across the U.S. EEZ in the Pacific. Discussions focused primarily on priorities for the characterization of deep-water (>200-meter depths) benthic biological...

Biological and practical tradeoffs in planting techniques for submerged aquatic vegetation Biological and practical tradeoffs in planting techniques for submerged aquatic vegetation
Global loss of submerged aquatic vegetation (SAV) and associated ecosystem function has prompted an interest in SAV revegetation, particularly where underlying stressors such as nutrient enrichment are mitigated, yet natural recruitment remains low. Typically, SAV is hand-planted, but alternative reliable and practically scalable SAV planting techniques are needed. In mesocosms, we...

Introduction of the Oriental Weatherfish, Misgurnus anguillicaudatus (Cantor, 1842) in the United States Introduction of the Oriental Weatherfish, Misgurnus anguillicaudatus (Cantor, 1842) in the United States
Although this fish had been present in the then United States (US) territory of Hawaii since the late 19th century, a growing number of collections in the contiguous US over a century later in the 2000s is noteworthy. The Oriental Weatherfish, also often referred to as the weather loach or dojo, is native to eastern Asia from Siberia to Vietnam thus covering a wide climatic range from...

Mangroves and people: Impacts and interactions Mangroves and people: Impacts and interactions
Mangroves have long been associated with human populations, as coastal communities rely on the various ecosystem services that mangroves provide. However, human degradation and destruction of mangrove forests is common, despite and because of our reliance on them as valuable ecosystems. Mangrove research and management must elucidate and reconcile these conflicts to maintain mangrove...

Red imported fire ants reduce invertebrate abundance, richness, and diversity in Gopher Tortoise burrows Red imported fire ants reduce invertebrate abundance, richness, and diversity in Gopher Tortoise burrows
Gopher Tortoise (Gopherus polyphemus) burrows support diverse commensal invertebrate communities that may be of special conservation interest. We investigated the impact of red imported fire ants (Solenopsis invicta) on the invertebrate burrow community at 10 study sites in southern Mississippi, sampling burrows (1998–2000) before and after bait treatments to reduce fire ant populations...

Identifying information gaps in predicting winter foraging habitat for juvenile Gulf Sturgeon Identifying information gaps in predicting winter foraging habitat for juvenile Gulf Sturgeon
The Gulf Sturgeon Acipenser oxyrinchus desotoi is an anadromous species that inhabits Gulf of Mexico coastal waters from Louisiana to Florida and is listed as threatened under the U.S. Endangered Species Act. Seasonal cues (e.g., freshwater discharge) determine the timing of spawning and migration and may influence the availability of critical habitat during winter months in six...

Strategic habitat conservation for beach mice: Estimating management scenario efficiencies Strategic habitat conservation for beach mice: Estimating management scenario efficiencies
The Perdido Key beach mouse (Peromyscus polionotus trissyllepsis), Choctawhatchee beach mouse (P. p. allophrys), and St. Andrew beach mouse (P. p. peninsularis) are 3 federally endangered subspecies that inhabit coastal dunes of Alabama and Florida, USA. Conservation opportunities for these subspecies are limited and costly. Consequently, well‐targeted efforts are required to achieve...

Effective population size remains a suitable, pragmatic indicator of genetic diversity for all species, including forest trees Effective population size remains a suitable, pragmatic indicator of genetic diversity for all species, including forest trees
Fady & Bozzano highlight some challenges to a proposed Convention on Biological Diversity (CBD) indicator of genetic diversity based on effective population size, Ne (Fady and Bozzano, 2020; Hoban et al., 2020). We appreciate the thoughtful debate and concur that genetic diversity indicators must be reliable and scalable. We fully agree that “genetic diversity should be better considered...
