The processes that control diversification and speciation in deep-sea species are poorly known. Here, we analyzed data produced by Restriction-Site Associated DNA Sequencing (RAD-Seq) of octocorals in the genus Paramuricea to elucidate diversification patterns and examine the role of environmental gradients in their evolution. The genus Paramuricea evolved around 8 MYA, with a high probability of a broad ancestral depth range...

Fresh groundwater is a critical resource supporting coastal ecosystems that rely on low-salinity, nutrient-rich groundwater discharge. This resource, however, is subject to contamination from point- and nonpoint-sources such as on-site sewage disposal systems (OSDS) and urban developments. Thus, the significance of flow and transport processes near the coastline due to density effects and water circulation in a complex hydroge...

The role of the composition of surface‐coating materials in controlling trace metal adsorption in aquatic environments was investigated using natural biofilms that developed on glass slides in three New York State lakes and a water𠄃supply well. Adsorption isotherms were obtained for Pb binding to each of the biofilms in solutions with defined Pb speciation at 25°C and pH 6.0, with Pb concentrations ranging from 0.2 to 2.0 μM....
