Loss and Transformation of Coastal Wetlands due to Global Change in the Conterminous United States: Past, Present, and FutureNARA Subscribed
Coastal wetlands are being transformed by global change, impacting the ecological and societal benefits provided by these ecosystems. Synthesizing knowledge of historical and expected future transformations in coastal wetlands can help inform forward-looking planning and stewardship efforts. Here, we review anticipated future ecological transformations in coastal wetlands of the conterminous United States and contrast them wit...
Improving wetland management through First Nations’ knowledge and a spatial visualisation toolNARA Subscribed
As wetlands continue to decline, there is an urgent need to improve their management by following the guidelines of international programs. The Ramsar Convention on Wetlands requires assessing baseline conditions and monitoring, for which Earth Observations are powerful tools. However, spatial and temporal limitations require integrated co-management, incorporating First Nations' Knowledge. We address three case studies with u...
From Genes to Greens: How Diet, Climate and Phylogeny Shape Freshwater Turtle MicrobiotasNARA Subscribed
Reptile microbiotas remain poorly understood despite their importance for host ecology and evolution. This study investigated how diet, climate and evolutionary history shape the gut microbiota of 234 Australian freshwater turtles spanning 10 species, four climatic zones and contrasting trophic strategies. It was found that turtles' microbiotas were dominated by Pseudomonadota, Actinobacteriota and Bacteroidota. Microbial rich...
Comparing phosphatised galleried stereom of Ordovician Cincinnaticrinus to modern Endoxocrinus illustrates preservation by micromoldingNARA Subscribed
Fossil echinoderm ossicles are often occluded by syntaxial overgrowths which obscure stereom. Phosphatized ossicles from insoluble residues show fine microstructure. We investigated phosphatized stereom in Cincinnaticrinus columnals in insoluble residues from the Ordovician around Cincinnati, Ohio USA. Microstructures appeared to be stereom micromolds. We tested this hypothesis by examining residue and thin sections of undisso...
