"If it does not, either the virus becomes weakened or the species changes".
But indirect trophic effects, where one species changes another species in some way that benefits a third species, are difficult to detect and to document.
Oxidation-reduction reaction, also called redox reaction, any chemical reaction in which the oxidation number of a participating chemical species changes.
Color: Variable, often solid green but brown, brick red or cream, sometimes mottled; like many gonodactyloids, this species changes color depending on habitat color and depth.
Just as changes in a species' habitat favor the evolution of new species, changes in tissue environments favor the growth of cancerous cells.
It is possible to downscale Red List Indices spatially by combining information on species' changes in Red List status with the range maps compiled as required documentation for each species' assessment.
The environment of Mo species changes from isolated tetrahedral MoO42− in the initial gel to distorted octahedra in γ-Bi2MoO6 (Raman, XANES).
This species changes the redox potential of tritiated water, which is shifted to a value in the passive or transpassive region.
While juvenile brook trout can outcompete brown trout, there is significant evidence of brown trout displacing adult brook trout as the competition between the species changes over the lifetime of the fish.
But for over four decades, with the blessing of Makah leaders, Tatoosh has been the object of intense biological scrutiny, and scientists say they are seeing disturbing declines across species — changes that could prove a bellwether for oceanic change globally.
Our purpose, besides exploring these particular model reactions, is to understand how the mechanism of bond activation changes as the catalytically active species changes from a simple, uncoordinated metal atom to a metal ligand coordination complex.
