Cold fronts and reservoir limnology: an integrated approach towards the ecological dynamics of freshwater ecosystems.
In this paper the authors discuss the effects of cold fronts on the dynamics of freshwater ecosystems of southeast South America. Cold fronts originating from the Antarctic show a monthly frequency that promotes turbulence and vertical mixing in reservoirs with a consequence to homogenize nutrient distribution, dissolved oxygen and temperature. Weak thermoclines and the athelomixis process imme...
متن کاملUsing Landscape Limnology to Classify Freshwater Ecosystems for Multi-ecosystem Management and Conservation
Governmental entities are responsible for managing and conserving large numbers of lake, river, and wetland ecosystems that can be addressed only rarely on a case-by-case basis. We present a system for predictive classification modeling, grounded in the theoretical foundation of landscape limnology, that creates a tractable number of ecosystem classes to which management actions may be tailored...
متن کاملEducational Programs: Alternative Swine Housing Educational Programs
Swine production facilities in the United States have adopted technological advancements in response to problems and opportunities as they arise. The first pressure was due mostly to economics. To improve feed efficiency, animals were moved into climate controlled buildings. To reduce labor costs, manure was handled as a liquid through slatted floors and feed and water systems were automated. L...
متن کاملControlling cyanobacterial harmful blooms in freshwater ecosystems
Cyanobacteria's long evolutionary history has enabled them to adapt to geochemical and climatic changes, and more recent human and climatic modifications of aquatic ecosystems, including nutrient over-enrichment, hydrologic modifications, and global warming. Harmful (toxic, hypoxia-generating, food web altering) cyanobacterial bloom (CyanoHAB) genera are controlled by the synergistic effects of...
متن کاملPersistence of Environmental DNA in Freshwater Ecosystems
The precise knowledge of species distribution is a key step in conservation biology. However, species detection can be extremely difficult in many environments, specific life stages and in populations at very low density. The aim of this study was to improve the knowledge on DNA persistence in water in order to confirm the presence of the focus species in freshwater ecosystems. Aquatic vertebra...
