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, ...

Conservation Planning for US National Forests: Conducting Comprehensive Biodiversity Assessments

T US National Forest Management Act (NFMA) is an essential statute for maintaining biotic diversity on 192 million acres of national forests and national grasslands. It was enacted in 1976 as reform legislation in response to environmental impacts from timber harvest, grazing, and mining on national forest lands, which the public and Congress found increasingly unacceptable (Wilkinson and Ander...

Biodiversity of Aspergillus species in soils of the National Park of Urmia Lake (NW Iran)

In the present study, nine species of Aspergillus, viz., A. alliaceus, A. ochraceus, A. persii, A. leproris, A. parasiticus, A. fumigatiaffinis, A. sydowii, A. niger, A. tubingensis and Eurotium amstelodami were obtained and identified from soils of the National Park of Urmia Lake, based on cultural and morphological characteristics. All of the species are newly recorded from hypersaline soils ...

Keystone species: toward an operational concept for marine biodiversity conservation

Various definitions and indices have been proposed in the literature to identify keystone species. In this study, we intended to make the concept of keystone species operational for marine biodiversity conservation. We used an exclusive definition of keystone species, based on the original concept of keystone predator, and derived a new functional index of keystoneness (KS) from an ecosystem-mo...
