The Evolution Of Sensory Divergence In The Context Of Limited Gene Flow In The Bumblebee Bat, Sebastian J. Puechmaille, Meriadeg Ar Gouilh

The sensory drive theory of speciation predicts that populations of the same species inhabiting different environments can differ in sensory traits, and that this sensory difference can ultimately drive speciation. However, even in the best-known examples of sensory ecology driven speciation, it is uncertain whether the variation in sensory traits is the cause or the consequence of a reduction in levels of gene flow. Here we show strong genetic differentiation, no gene flow and large echolocation differences between the allopatric Myanmar and Thai populations of the world's smallest mammal, Craseonycteris thonglongyai, and suggest that geographic isolation most likely preceded sensory …


Sulfate And Phosphate Speleothems At Jenolan Caves, New South Wales, Australia, Ross E. Pogson, R. Armstrong L. Osborne, David M. Colchester Apr 2011

Sulfate And Phosphate Speleothems At Jenolan Caves, New South Wales, Australia, Ross E. Pogson, R. Armstrong L. Osborne, David M. Colchester

KIP Articles

Sulfate and phosphate deposits at Jenolan Caves occur in a va- riety of forms and compositions including crusts, ‘flowers’ and fibrous masses of gypsum (selenite), and clusters of boss-like speleothems (potatoes) of ardealite (calcium sulphate, phos- phate hydrate) with associated gypsum. This boss-like mor- phology of ardealite does not appear to have been previously described in the literature and this is the first report of ardealite in New South Wales. Gypsum var. selenite occurs in close association with pyrite-bearing palaeokarst, while the ardealite gypsum association appears to relate to deposits of mineralised bat guano. Isotope studies confirm that the two …
