Hierarchies of Cause: Toward an Understanding of Rarity in Vascular Plant Speciesies intrinsic to these time/space parameters are explored and an importance hierarchy of causes of rarity is proposed for each class. These hierarchies serve as the basis for a predictive classification. Human causes of rarity such as habitat destruction and taxonomic difficulties are not considered

Peasant Farming Systems, Agricultural Modernization, and the Conservation of Crop Genetic Resources al to developing countries and industrialized nations alike. Native varieties expand and renew the crop genetic resources of developed countries while also performing well under the ecological and economic conditions of the traditional farms where they are grown. With agricultural modernization and

The New Paradigm in Ecology: Implications for Conservation Biology Above the Species Levelconservation is only one of the various goals that has directed the preservation and management of natural areas and resources. Resource management goals have largely been utilitarian or commercial, such as the maintenance of large areas for watersheds; preservation of marshes, bogs, and seasonal we

Reptilian Extinctions: The Last Ten Thousand Yearstions have occurred on islands, and they are usually due to human-related disturbance. The effects of human-related disturbance are calibrated by measuring the rate of extinction for two sets of Holocene landbridge islands where human impact has been minimal. Extinction rates for islands with a hist

Loss of Biodiversity in Aquatic Ecosystems: Evidence from Fish FaunasFish also have a major impact on the distribution and abundance of other organisms in waters they inhabit. Examination of trends in freshwater fish faunas from different parts of the world indicate that most faunas are in serious decline and in need of immediate protection. Species most likely to be

Threats to Invertebrate Biodiversity: Implications for Conservation Strategiesats to invertebrates and concern about detrimental effects of loss of invertebrate diversity. I summarize the geographic distribution of extinct and threatened U.S. invertebrates, discuss reasons for recent extinctions, and comment on the role invertebrates should play in conservation strategies.

Forest Fragmentation and the Conservation of Biological Diversityragmentation differs from habitat patchiness, and it is illustrated how forest fragmentation is distinguished from a series of forest fragments and a single tract of insular forest. Five types of fragmentation are illustrated, and land use in and around the Ocala National Forest illustrates how thes

Issues of Scale in Conservation Biologya new light, the resolution is obvious, and we wonder how we could have ever been so stupid. Is it possible to identify “new lights” at the outset, and then proceed to determine which might best illuminate the problem at hand?
