Conservation Biology for the Biodiversity Crisis: a Freshwater Follow-up

In their essay “Conservation Biology for the Biodiversity Crisis,” Olson et al. (2002) identify critical research gaps hampering effective conservation planning, with an emphasis on the terrestrial realm. The situation for freshwater biodiversity is so grave that an additional plea for freshwater research is warranted. Freshwater fish alone comprise one-fourth of all living vertebrate species, ...

Freshwater biodiversity conservation: recent progress and future challenges

Freshwater habitats occupy ,1% of the Earth’s surface, yet are hotspots that support ,10% of all known species, and ,M of vertebrate species. Fresh waters also are hotspots for human activities that have led to widespread habitat degradation, pollution, flow regulation and water extraction, fisheries overexploitation, and alien species introductions. These impacts have caused severe declines in...

Prioritisation of micro-catchments based on morphology

Two multicriterion decision-making methods, namely ‘compromise programming’ and the ‘technique for order preference by similarity to an ideal solution’ are employed to prioritise 22 micro-catchments (A1 to A22) of Kherthal catchment, Rajasthan, India and comparative analysis is performed using the compound parameter approach. Seven criteria – drainage density, bifurcation ratio, stream frequenc...

Freshwater biodiversity and conservation planning: introduction to the virtual supplement

The January 2011 Special Issue is the first major compilation of studies on systematic conservation planning in fresh waters (Turak & Linke, 2011). The papers in this Special Issue consolidate freshwater conservation planning as a field within both conservation science and freshwater ecology. This progress is largely a result of key advances in both disciplines (Linke, Turak & Nel, 2011). Many ...
