The mechanisms through which father absence affects reproduction may differ in different ecological contexts.
Whereas the number of common inversions observed in different ecological or geographic parts of the species range may differ significantly, such is not the case for RCIs.
These populations live in very different ecological conditions and differ in a number of behaviors, including behaviors mediated by the lateral line, such as schooling (Wark et al. 2011).
Chagas exists in two different ecological zones.
Imagine a patchy environment where the habitat patches differ in ecological conditions (here symbolised by seeds of different size).
Research on salmonid systems has greatly enhanced our understanding of hierarchical divergence; in fact, genetic variance is normally larger between salmon populations inhabiting different basins than between salmon populations from the same basin that differ in ecological attributes [ 2, 3, 13, 14].
To test this hypothesis we collected songbird point count data across broad biophysical gradients and gradients in forest patch edge density in the west and east slopes of the Cascade Mountains of Oregon and Washington, U.S.A., which differ in ecological productivity.
Interest in yellow skin colour might likewise be the result of some anomalous ecological or cultural factor, and it would therefore be instructive to attempt replication of our findings in populations with differing social and ecological backgrounds.
Individual plants of emmer wheat were collected at random, at least 1 m apart, from populations differing in major ecological properties.
In 2010, serovars also differed in geographic distribution, with variations in seroprevalence between islands and different ecological zones within the main island.
