Recent rapid increases in the right whale ( Eubalaena australis ) population off southern Brazil
Right whales (Eubalaena australis) that gather on a wintering ground off southern Brazil have been aerial surveyed and photographically identified since 1987. As of 2003 the Brazilian Right WhaleExpand
Population variation in tooth, jaw, and root size: a radiographic study of two populations in a high-attrition environment.
Radiographs were taken of the jaws of skeletal remains of two populations of different-phenotype Prehistoric Australians from Roonka and Early New Zealanders (Maoris). On these radiographs crown,Expand
Post-pleistocene changes in tooth root and jaw relationships.
Mandibles of 126 sexed skeletal specimens, from Near Eastern sites dating over the past 12,000 years were radiographed. From the radiographs obtained, digitised tracings were made of crown lengthExpand
An introduced parasitic fly may lead to local extinction of Darwin's finch populations.
Introduced pathogens and other parasites are often implicated in host population level declines and extinctions. However, such claims are rarely supported by rigorous real-time data. Indeed, theExpand
A model evaluating the contribution of environmental factors to the production of resting eggs in the rotifer Brachionus plicatilis
The production of resting eggs by the rotifer Brachionus plicatilis was tested at four salinities (9, 18, 27 and 36\%) and six concentrations of the alga Chlorella stigmatophora (0.25, 0.5, 1.0, 2.0,Expand
