Species Biology and Conservation Funding

Science, 2002
In his Policy Forum “Conservation priorities for Russian mammals” (16 Aug., p. [1123][1]), L. V. Polishchuk notes that limited government financial resources are often devoted to the conservation of only a few, high-profile flagship species.

The biology of reactive sulfur species (RSS)

Plant Physiology and Biochemistry, 2012
Sulfur is an essential and quantitatively important element for living organisms. Plants contain on average approximately 1 g S kg⁻¹ dry weight (for comparison plants contain approximately 15 g N kg⁻¹ dry weight). Sulfur is a constituent of many organic molecules, for example amino acids such as cysteine and methionine and the small tripeptide ...

Definitions of Species in Biology

The British Journal for the Philosophy of Science, 1969
One of the major problems confronting biologists is that of classifying organisms. This is usually done in a hierarchical manner. First, organisms are grouped together into classes (called 'taxa' by biologists) which are assumed to be incapable of significant subdivision; then, these classes are in turn grouped so that the members of a number of ...

The Population Biology of Invasive Species

Annual Review of Ecology and Systematics, 2001
▪ Abstract  Contributions from the field of population biology hold promise for understanding and managing invasiveness; invasive species also offer excellent opportunities to study basic processes in population biology. Life history studies and demographic models may be valuable for examining the introduction of invasive species and identifying life ...

The Evolutionary Biology of Species

2019
Abstract‘Species’ are central to understanding the origin and dynamics of biological diversity; explaining why lineages split into multiple distinct species is one of the main goals of evolutionary biology. However, the existence of species is often taken for granted, and precisely what is meant by species and whether they really exist as a pattern of ...
