Tropical speciation (1 Viewer)

Richard, thanks as always for the link

Anyone who has been following the various papers and SACC proposals on speciation (or not) of various sub-oscines across the interfluvia in the Amazon won't be entirely surprised by the conclusions in respect of rivers, whilst the similarity of "species pairs" across the Andean chain (eg Choco vs Amazonian) would suggest the Andean uplift was unlikely to be responsible!

"The new research, published today in the journal Nature, suggests that tropical bird speciation is not
directly linked to geological and climate changes, as traditionally thought, but is driven by
movements of birds across physical barriers such as mountains and rivers that occur long
after those landscapes’ geological origins."

cheers, alan
Competitive Interactions upon Secondary Contact Drive Elevational Divergence in Tropi

Not quite speciation directly, but I thought it would be relevant to this thread nonetheless.
