The Linnaean Enterprise: Past, Present, and Future1
|
IT CAN BE reasonably assumed that the first words to emerge during the origin of human speech included the names of plants and animals. That advance, which probably occurred during the transition from Homo erectus to Homo sapiens a half million years ago, can be regarded as the earliest forerunner of science. Accuracy and repeatability in communication about the environment were then as now necessary for survival. Getting things by their right names, as the Chinese put it, is the first step t...

What is Meant by "95% of Species"? An Argument for the Inclusion of Rapid Tolerance Testing
Human and Ecological Risk Assessment
; ABSTRACT It is increasingly common for water quality guidelines and risk assessments to consider the proportion of species at risk from a particular toxicant, based on the species sensitivity distribution (SSD) for that toxicant. There is a premise that the sensitivity data from species included in

Species assemblages and indicator species: the need for a flexible asymmetrical approach.
Ecological Monographs
; INTRODUCTION The identification of characteristic or indicator species is a traditional activity in ecology and biogeography. Studies based on field work, describing sites or habitats, usually mention one or several species characterizing each habitat. So, it is surprising that several standardized

WHICH TRAITS OF SPECIES PREDICT POPULATION DECLINES IN EXPERIMENTAL FOREST FRAGMENTS?
Ecology
; KENDI F. DAVIES [1,4] CHRIS R. MARGULES [2] JOHN F. LAWRENCE [3] Abstract. Theory suggests that species with particular traits are at greater risk of extinction than others. We assumed that a decline in abundance in forest fragments, compared to continuous forest, equated to an increase in

Trophic rank and the species-area relationship.
Ecology
; INTRODUCTION The tendency for species richness to increase with area (the species - area relationship ) is one of the most robust empirical generalizations in ecology (May 1975, Rosenzweig 1995). Most studies of species - area patterns have focused on particular taxa, guilds, or functional groups,
