Henipavirus susceptibility to environmental variables [PDF]

open access: yesVirus Research, 2008
(Uploaded by Plazi for the Bat Literature Project) The routes of henipavirus transmission between hosts are poorly understood. The purpose of this study was to measure the persistence of henipaviruses under various environmental conditions and thereby gain an insight into likely mechanisms of transmission. Henipaviruses survived for more than 4 days at

Evolution and the Regulation of Environmental Variables [PDF]

open access: yes, 2005
The idea that the biota can regulate the abiotic components of their environment to levels suitable for life has attracted criticism from neo-Darwinian theorists but is still a viable hypothesis. Here we present a model, similar to Daisyworld [1] but more general, which allows for a more extensive study of the compatibility of biotic regulation with ...

Genetic Variability in the Deep Sea: Relation to Environmental Variability [PDF]

open access: yesEvolution, 1972
A current concept of population biology holds that much genetic variability is maintained in populations as an adaptation tc environmental heterogeneity in time and space (Battaglia, 1963; Bretsky and Lorenz, 1971; Burns and Johnson, 1971; Powell, 1971). Environmental heterogeneity is thought to promote genetic variability by mechanisms of diversifying
