Changing Only Slowly: The Role of Phylogenetic Niche Conservatism in Caviidae (Rodentia) Speciation
Journal of Mammalian Evolution, 2020The dynamics of species diversification have attracted significant scientific attention in recent decades. Many lineages tend to maintain their niche characteristics over evolutionary time, a phenomenon known as phylogenetic niche conservatism (NC), which can slow the processes of ecological speciation by diversification selection.

Guinea pig related rodents possess numerous derived placental characters. We attempt to identify diversity within the visceral yolk sac and its association with the chorioallantoic placenta in three species of caviids, two of them possessing a capsule formed by the decidua that covers the chorioallantoic placenta.

The impact of gnawing byMicrocavia australison the survival ofGeoffroea decorticansplants was studied in the Monte Desert of Argentina. Sampled plants (N=105) were selected randomly from two different colonies ofM. australis. For each plant sampled the following properties were measured: the diameter of the trunk at ground level; the distance to the ...

The diversity of terrestrial mammals in South America is the result of both isolation and continental interchanges, preceded and followed by extinction and speciation (Simpson 1980; Marshall 1988). Mammalian biodiversity in South America can be partitioned into three major phases, beginning in the Paleocene (65.5–55.8 million years ago – Ma) with ...
