Factors influencing the spatio-temporal dynamics of plankton communities in small tropical lakes are not well understood. This study assessed plankton communities in response to spatial and seasonal (wet vs dry seasons) changes in environmental variables in Lake Kanyaboli, a small satellite lake on the northern shores of Lake Victoria, Kenya. Water quality variables, including pH, conductivity (EC), dissolved oxygen (DO), temperature, Secchi depth (SD), nitrates (NO3-), nitrites (NO2-), ammonium (NH4+), soluble reactive phosphorus (SRP), total nitrogen (TN), total phosphorus (TP), and chloroph...

The concept of “biocultural diversity” has gained wider prominence in recent decades as academics, institutions, and practitioners have expanded cross-disciplinary work at the intersection of human culture and biological diversity. Within the conservation realm, this trend has helped raise the profile of issues like Indigenous rights and traditional knowledge, especially since the mid-2010s as many […]

Copyright © 2021 Albuquerque Journal New Mexico temperatures will likely continue to climb over the next 50 years, state geologist Nelia Dunbar said this week – a change with major consequences for regional water supplies and landscapes. Dunbar, the New Mexico Bureau of Geology and Mineral Resources director, serves on the eight-member advisory panel crafting a “leap-ahead climate analysis” for the Interstate Stream Commission of what water supplies could look like in 2070.

A warmer climate could impact nearly every aspect of New Mexico’s water and land. Dunbar listed likely impacts, including: • Decreased aquifer recharge, more common and hotter drought periods, earlier winter runoff, greater groundwater demands and stress on plant life. • Dry vegetation and catastrophic wildfires that could affect runoff and floodplain ecosystems. • Warmer streams and rivers that could mean changing oxygen levels, which can disturb fish habitat. “Likely the dominant impact on water quality going forward is going to be related to temperature increase,” Dunbar said. ...

DNA sequencing from water and leech bloodmeals helps identify novel mammalian viruses In a new scientific investigation headed by the German Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), water from African and Mongolian waterholes as well as bloodmeals from Southeast Asian leeches were assessed for the ability to retrieve mammalian viruses without the need to find and catch the mammals. The scientists analyzed the samples using high throughput sequencing to identify known viruses as well as viruses new to science. Both approaches proved to be suitable tools for pandemic preve...
