The Great American Biotic Interchange: Dispersals, Tectonics, Climate, Sea Level and Holding Pens
TLDR
The biotic and geologic dynamics of the Great American Biotic Interchange are reviewed and revised and trans-isthmian land mammal exchanges during the Pleistocene glacial intervals appear to have been promoted by the development of diverse non-tropical ecologies.Abstract:
The biotic and geologic dynamics of the Great American Biotic Interchange are reviewed and revised Information on the Marine Isotope Stage chronology, sea level changes as well as Pliocene and Pleistocene vegetation changes in Central and northern South America add to a discussion of the role of climate in facilitating trans-isthmian exchanges Trans-isthmian land mammal exchanges during the Pleistocene glacial intervals appear to have been promoted by the development of diverse non-tropical ecologiesread more

Climate change and the past, present, and future of biotic interactions
TL;DR: This work highlights episodes of climate change that have disrupted ecosystems and trophic interactions over time scales ranging from years to millennia by changing species’ relative abundances and geographic ranges, causing extinctions, and creating transient and novel communities dominated by generalist species and interactions.

TL;DR: An exhaustive review and reanalysis of geological, paleontological, and molecular records converge upon a cohesive narrative of gradually emerging land and constricting seaways, with formation of the Isthmus of Panama sensu stricto around 2.8 Ma.

TL;DR: It is concluded that protecting a diversity of abiotic conditions will likely best conserve biodiversity into the future in places where abiotic drivers of species distributions are strong relative to biotic drivers, where the diversity ofAbiotic settings will be conserved through time, and where connectivity allows for movement among areas providing different abiotic Conditions.

TL;DR: It is shown that Musteloidea emerged approximately 32.4-30.9 million years ago in Asia, shortly after the greenhouse-icehouse global climate shift at the Eocene-Oligocene transition and that the morphological adaptations of badgers, martens, weasels, polecats, minks, and minks each evolved independently more than once within Mustelidae.

Splendid and Seldom Isolated: The Paleobiogeography of Patagonia
TL;DR: The idea that South America was an island continent over most of the Cenozoic, during which its unusual mammalian faunas evolved in isolation, is outstandingly influential in biogeography as discussed by the authors.
