Biologists are nearly unanimous in their belief that humanity is in the process of extirpating a significant portion of the earth's spe­ cies. The ways in which we are doing so reflect the magnitude and scale of human enterprise. Everything from highway construction to cattle ranch­ ing to leaky bait buckets has been implicated in the demise or endan­ germent of particular species. Ac­ cording to Wilson (1992), most of these activities fall into four major categories, which he terms "the mind…

Success factors in the establishment of human-dispersed organisms

Introduction As recently as a decade ago, exotic organisms—species dispersed beyond their native ranges by human activities—rarely ranked high among recognized threats to biodiversity. Habitat loss

Ritual Releasing of Wild Animals Threatens Island Ecology

How the ritual freeing of wildlife promotes an invasion of nonnative species, that is threatening the fragile islandenvironment of Taiwan is discussed.

Biological invasions—How are they affecting us, and what can we do about them?

—Nonindigenous species affect native ecosystems, communities, and populations in myriad ways, from plants (and a few animals) that overgrow entire communities, to plants and animals that hybridize

The story behind the IFAS assessment of in Florida ’ s natural areas . NON-NATIVE PLANTS Letter to Wildland Weeds

Introduction There is a growing awareness of the problems related to non-native invasive species: for example, the Wilcove et al. (1998) report which indicated that invasive species are second only

How many endangered species are there in the United States

This work reviews the best available data on the status of plants, animals, and fungi in the US and concludes that the actual number of known species threatened with extinction is at least ten times greater than the number protected under the Endangered Species Act (ESA).

Exotic species introductions into South America: an underestimated threat?

It is hypothesized that the GABI may have acted as an 'extinction filter', leaving faunal groups of mostly South American origin relatively more threatened by the current wave of exotic invaders than those with prominent North American representation.

Conservation status of imperiled north American freshwater and diadromous fishes

This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989, and reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa.

Biodiversity Drifts in Agricultural Landscapes

We are in the midst of the sixth global mass extinction event (McNeely & Scherr, 2002; Thomas et al., 2004). Around the globe, biological communities that took millions of years to develop—including

Exploitation of endangered mammals in the United States

Overexploitation is a pervasive threat to mammal species worldwide and ranks second to habitat destruction as the major cause of their decline in the United States. Fine-scale analyses and

Why Do Introduced Species Appear to Devastate Islands More Than Mainland Areas

It is unlikely that, by virtue of their reduced species richness alone, island communities pose less "biotic resistance" to invaders than mainland communities do, but certain entire groups of species, like terrestrial mammals, are often missing from islands, and these absences can predispose certain invaders to be especially likely to survive and to produce particular invaders.

Threats to Imperiled Freshwater Fauna

Threats to imperiled freshwater fauna in the U.S. were assessed through an experts survey addressing anthropogenic stressors and their sources. Specifically, causes of historic declines and current

Threatened and endangered species geography: characteristics of hot spots in the conterminous United States

An estimated global extinction rate that appears to be unprecedented in geological time has heightened concern for the increasing number of rare species and rarity has been used as an important criterion for identifying which species should be the focus of conservation efforts.

Nonindigenous aquatic species in a United States estuary: a case study of the biological invasions of the San Francisco Bay and delta

The San Francisco Bay/Delta Estuary hosts more nonindigenous species than are known for any other estuary, with 212 established species, 15 species too recently arrived to determine whether they have

Assessing Threats and Setting Priorities for Conservation

The purpose of this comment is to discuss and to compare briefly some systems for prioritizing species for conservation attention. This comment is written in response to a proposed new International

Diversity of life

It is clear that the above can lead to confusion when scientists of different countries are trying to communicate with each other, so an internationally recognized system of naming organisms is created.

Fishes of North America Endangered, Threatened, or of Special Concern: 1989

Comparison of the 1979 and 1989 list of rare North American fishes indicates that recovery efforts have been locally effective for some species, but are cleverer than was earlier believed.

The Pending Extinction of the Uncompahgre Fritillary Butterfly

Low estimates of heterozygosity indicate that genetic and demographic factors preceded by historic human disturbance are causing the decline of B. acrocnema, which has an unknown capacity to persist in the face of local weather fluctuations and predicted regional warming trends.

Management Costs for Endangered Species

The cost of managing currently occupied habitats of U.S. endangered species threatened by alien species or the disruption of fire regimes totals at least $32–42 million per year (1997 $U.S.) and 60% of endangered species could face continued declines or extinction, even if their habitats are nominally protected.
