These stands will provide an opportunity for biogeographers
and population geneticists to study populations in the early stages of range expansion.
A number of biogeographers
have been focusing their studies on the MTZ, correlating and explaining its biota with both nearctic and neotropical influences.
Additionally, with continental forests subject to clear-cutting and bisection from development, biogeographers
, conservation biologists, and ecologists see an increasing "insularization" of ecosystems throughout the world.
This distinct distribution pattern of the endemic species from the southern part of the study region may reflect that the San Juan areas lie close to the limit of the Patagonian phytogeographic unit sensu Cabrera (1976), hence close to a general change in vegetation types that is widely recognized among biogeographers
have devoted considerable attention to the PNW (see Soltis and others 1997; Brunsfeld and others 2001; Hewitt 2004), and phylogeographic studies of terrestrial salamanders have contributed greatly to identifying population genetic structure of regional vertebrates.
The nearshore marine environment of coastal California (USA) has long been a playground for biogeographers
owing to its dynamic composition of marine organisms that has undergone dramatic shifts during the past five decades or so, particularly among marine fishes (Horn, et al.
This is a question that still intrigues biogeographers
, and their explanation is an outgrowth of the ideas that Gray posited in the 19th century (Wen, 1999).
do not recognize the Big Thicket as a crossroads or an independent or special ecological region (MacRoberts and MacRoberts, 2003; McLaughlin, 2007) but rather subsume it within a larger region or province.
This is absolutely true, although many ecologists, biogeographers
, behaviorists, conservationists, and physiologists do not like to think about it.
probably agree that the paleogeographic changes in the distribution of land and sea, as well as the uplift of the Andes, tepui mountains and other ranges, influenced the early evolution of the faunas during the Tertiary (of ca.
For the first time, biogeographers
, archaeologists and conservation workers have a resource which sets out the past and present distribution of birds from the Bismarck Archipelago to Easter Island.
Widespread Indo-Pacific shore-fish species: a challenger for taxonomists, biogeographers
, ecologists, and fishery and conservation managers.
