Spatial Genetic Structure and Diversity Reveal Central‐Marginal Patterns in the Rare Freshwater Mussel, Pleurobema riddelliiNARA Subscribed
Aim This study sought to evaluate how historical drainage connectivity and contemporary basin isolation have shaped population genetic structure and diversity in an imperilled species of freshwater mussel, Pleurobema riddellii. Location Covers the range of P. riddellii , spanning seven river basins of the Gulf Coastal Plains of the southern USA, including the San Jacinto, Neches, Sabine, Calcasieu, Red, Ouachita and Pearl rive...
Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservationNARA Subscribed
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time. Sharks, rays, and chimaeras (Chondrichthyes) have now been comprehensively assessed twice (1996–2011 and 2012–2021) with hindcast assessments from 1970 onward, yielding an unprece...
Correlation between DNA methylation and transcriptomic changes in golden Asian sea bass ( Lates calcarifer ): An integrated approachNARA Subscribed
Lates calcarifer , commonly known as barramundi perch, Asian sea bass or barramundi, is a significant aquaculture species across the Indo‐Pacific. Barramundi typically exhibit a silver to bronze wild‐type (WT) skin colour, with occasional golden (xanthic) variants of commercial interest. Although previous studies have identified gene expression differences between golden and WT variants, the genetic mechanism driving golden co...
Mapping area of habitat for inland wetland speciesNARA Subscribed
Area of habitat (AOH) maps provide a high‐resolution representation of the habitat available in a species’ range and can support conservation policy and planning processes. However, until recently, there was insufficient knowledge on the distribution of inland wetlands and freshwater biodiversity to develop AOH mapping methods specifically tailored to inland wetlands. We used a combined empirical and thematic approach to trans...
Environmental and Geographic Conditions on the Breeding Grounds Drive Bergmannian Clines in NightjarsNARA Subscribed
Aim To evaluate (1) whether three migratory nightjar species (Family Caprimulgidae) adhere to Bergmann's rule, (2) whether environmental factors on the breeding or wintering grounds determine body size, and (3) which mechanistic hypotheses best explain Bergmannian patterns in body size. Location North and South America; Europe and Africa. Taxon Eastern whip‐poor‐will ( Antrostomus vociferus ), Common nighthawk ( Chordeiles min...
Impacts of Climate Change Interventions on Biodiversity, Water, the Food System and Human Health and Well‐BeingNARA Subscribed
Climate change threatens biodiversity, water, food and human health and well‐being. Rapid, sustained mitigation and adaptation actions can benefit all these elements of the nexus. Key transitions in energy, land and marine ecosystems, urban areas, industry and society are essential for climate change mitigation, adaptation and sustainable development. These transitions require interdisciplinary research, policy support and soc...
An Overview of Vaccine Development Strategies for Columnaris‐Causing Bacteria in Cultured FishNARA Subscribed
Columnaris disease, caused by columnaris‐causing bacteria (CCB), affects cultured and wild freshwater fish worldwide. Belonging to the phylum Bacteroidota and the family Flavobacteriaceae, CCB are gram‐negative, yellow‐pigmented bacteria that are presumed ubiquitous in freshwater habitats. Since the first report of the disease in 1922, growth and survival, pathogenesis, and transmission of these pathogens have been intensely r...
With over 40 years of history, the multi-jurisdictional effort to restore the health of the Chesapeake Bay ecosystem has yielded some positive outcomes with water quality and natural resources showing measurable signs of improvement. The lessons learned from this multi-year, multi-jurisdictional restoration effort can provide understanding and guidance for ecosystem restoration efforts elsewhere. The 10 “lessons learned” from...
Skeletal morphometrics suggests high fitness of hybrid coral recruits under ocean warming and acidificationNARA Subscribed
Anthropogenic greenhouse gas emissions increase sea surface temperature and acidification, inhibiting calcification of reef-building corals. While ocean acidification is known to hinder skeletal development of newly settled coral recruits, little is known of its effects on older purebred or interspecific hybrid recruits, or its combined effects with temperature. Using 3D X-ray microscopy, we found that predicted mid-century oc...
The basis for attribution assessments of current extreme weather and climatic events such as droughts and floods is that the record of such events is of sufficient length to be able to compare the occurrence and severity of recent events with those in the past. If this assumption holds, then the magnitude and frequency of extreme hydrological events in the current anthropogenically forced climate can be compared with those in...
