Conserving Slow-Growing, Long-Lived Tree Species: Input from the Demography of a Rare Understory Conifer, Taxus floridana

Article Abstract:

Research on Taxus floridana population dynamics in northern Florida indicates that conservation efforts should not only protect already established reproductive individuals, but also enhance the survival of other individuals in different life-history stages that do not appear to directly or greatly contribute to population growth rates.

Intercrosses and the U.S. Endangered Species Act: Should Hybridized Populations be Included as Westslope Cutthroat Trout?

Article Abstract:

The authors recommend that only nonhybridized westslope cutthroat trout be included for listing under the Endangered Species Act, and cites relevant reasons. It is posited, however, that protection should be afforded to populations of undetermined status until further data becomes available.

Introduction: population biology, evolution and control of invasive species

Article Abstract:

Management and control of nonindigenous species is expected to be the biggest challenge for conservation biologists. Studies of genetic diversity and the potential for rapid evolution of invasive species provide a useful insight regarding the causes of their becoming invasive.
