Aquatic Conservation: Marine and Freshwater Ecosystems
1. The spatial distribution of the most important subtidal habitats (coral reefs, coral carpets, seagrass meadows, sand with corals, macroids, mud, hardgrounds) and mangroves was mapped in northern Safaga Bay, Red Sea, Egypt. Coral communities were analysed separately for their ecological and spatial patterns. This, coupled with information about major current patterns in the bay, provides a fr...
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 کاملAquatic Conservation: Marine and Freshwater Ecosystems
1. The natural hydropattern in the seasonally-flooded marl prairie wetlands of Everglades National Park has been severely disrupted by human water control activities, seriously impacting higher trophic organisms, e.g. wading birds, that depend on these wetlands. Less is known about the impacis on key aquatic fauna, such as crayfish Procambarus alleni, or how these populations might respond to p...
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...
متن کاملAquatic Conservation: Marine and Freshwater Ecosystems
Millennial perspectives, like the one prompted by this Special Issue of Aquatic Conser6ation, are challenging. If we look back, we realize the degree of change in culture, technology, science and environmental quality that can occur over such time scales. Consider, for example, that by the turn of the last millennium, our global population was somewhere between 200 and 500 million (Ehrlich et a...
