Watershed boundaries and geographic isolation: patterns of diversification in cutthroat trout from western North America. BMC Evolutionary Biology 12:38 (http://www.biomedcentral.com/1471-2148/12/38)Loxterman, J.L., and Keeley, E.R. (2012). Watershed boundaries and geographic isolation: patterns...
When oceanic islands are far enough apart to permit populations to evolve in isolation, but close enough to allow occasional dispersions to occur, they are effectively outdoor laboratories of evolution. The Galapagos island chain is one of the world’s greatest showcases of evolution. Each island ...
ForPachydactylusand its relatives, two variable traits of interest that may promote geographic isolation are body size and habitat preference. There is substantial body size variation inPachydactylusand related genera, with the largest and smallest species having adult snout–vent lengths of 35 and 1...
Such so-called micro-endemic species (Ochoa-Ochoa et al. 2011) have been described from desert springs throughout the world (Ponder and Colgan 2002; Witt et al. 2006; Murphy et al. 2013). Geographic isolation among desert springs may also influence demographic processes such as population ...

A 40-mile stretch of a long-gone branch of the Nile may explain why the ancient monuments were built where they were.
Here, then, is the puzzle: most New Zealand triplefin species evolved from a common ancestor, yet are found throughout New Zealand waters. There is thus no evidence from current species distribution patterns for the geographic isolation that normally precedes speciation. Did some of the New ...
but the distinctness of the populations in the Ruby-East Humboldt Mountains suggests these ranges may harbor unique genetic variation. The accelerated rate of pika population losses in recent decades in this ecoregion could certainly be associated with range isolation, mountain range size, as well as...
In contrast, since the first wave of COVID-19 in early 2020, China has adopted a "zero COVID″ policy, implementing a series of non-pharmaceutical interventions (NPIs), including contact tracing and isolation, strict border control, and massive testing. From 21 Feb to 17 March 2020, the ...
