Categorization Systems of Threatened Species
Conservation Biology, 2007de Grammont and Cuar´on (2006) provide interestinginformation about the way several countries of the West-ern Hemisphere address the issue of developing systemsfor threatened species categorization. Nevertheless, wedisagree with these authors on some fundamental pointsand think their conclusions that “the country categoriza-tions [they] evaluated have ...

Optimal Learning and Management of Threatened Species
Management Science, 2023Amid an unprecedented loss of biodiversity, a pressing issue is how to improve the efficiency of conservation with limited resources and information. Collecting data on species with a small population is costly and time consuming, and many high-stakes decisions need to be made based on limited data.

Designing for connection with local threatened species
Interactions, 2022Australia-like much of the world-is facing a biodiversity crisis. Hundreds of species are in danger of extinction due to the destruction and degradation of their habitats. Populations of threatened species have more than halved since 1985. To have a chance at survival, these species require federal government recovery plans for funding and habitat ...

Threatened species not necessarily rare, rare species not necessarily threatened
Environmental Conservation, 1997In the beautifully-illustrated book of rare and threatened plants of Greece (Phitos et al. 1995), the selection of species is based strictly on the four World Conservation Union (IUCN) categories of ‘extinct’, ‘endangered’, ‘vulnerable’ and ‘rare’ (Lucas & Synge 1978). The Swedish ‘red data’ book of plants (Aronsson et al.

Conservation Genomics of Threatened Animal Species
Annual Review of Animal Biosciences, 2013The genomics era has opened up exciting possibilities in the field of conservation biology by enabling genomic analyses of threatened species that previously were limited to model organisms. Next-generation sequencing (NGS) and the collection of genome-wide data allow for more robust studies of the demographic history of populations and adaptive ...

The threatened status of acipenseriform species: a summary
Environmental Biology of Fishes, 1997...increased demand has recently driven the price of black market smoked sturgeon as high as $ 26 a kilogram. With poachers standing to gain roughly a third of this price [besides the much higher price of caviar], a large fish could be worth thousands of dollars.

Effects of Land Use on Threatened Species
Conservation Biology, 2009Abstract: There is widespread agreement that biodiversity loss must be reduced, yet to alleviate threats to plant and animal species, the forces driving these losses need to be better understood. We searched for explanatory variables for threatened‐species data at the country level through land‐use information ...

Saproxylic species are one of the most threatened organism groups. As with all forest species, they are suffering from the dwindling of forests. But the habitats of saproxylic species may also be decreasing in regions where, although the forest area is currently increasing, such as in Europe, practically all forests and other wooded areas have been ...
