“…Castillo et al (2005) were the first to provide estimates of potential ages of species of Ctenomys based on molecular clocks of multiple genetic loci; interestingly an expanded cytb dataset analyzed by those authors suggested an origin for the species of Ctenomys at about 3.7 Mya. This date is close to the estimate based on mitochondrial and nuclear loci provided by Upham and Patterson (2012) at ca. 4.3 Mya.…”

“…In particular, these few studies did not test whether dispersal or vicariance events effectively generated increases in net species diversification rates (e.g., Refs. [4,7,9,68]. For instance, Chaves et al [9] suggested that Andean uplift promoted increases in species diversification in the Adelomyia hummingbird genus.…”

One of the goals of evolutionary biology is understanding how biological diversification change across spatial and temporal scales. Theoretically, it has been established that external (i.e., dispersals) and internal (i.e., origin of a key innovations) factors can modulate shifts in rates of species diversification. However, the role of historical events as trigger of species diversification rates have not been well understood in empirical studies. I reviewed the literature linking historical biogeographic events and species diversification in many groups. Many of studies conclude that dispersals can be associated with exceptional changes in species diversification rates in insular and mainland areas. I discuss the limitations of some approaches used to discover the link between historical biogeography and macroevolution. I propose some predictions under biogeographic scenarios to gain understanding in how historical events promote biological diversification. I suggest that future studies linking biogeography and macroevolution should incorporate ecologically-relevant traits to discern the mechanisms underlying these historical associations. Although new developments in phylogenetic comparative methods have been done, still is necessary more traditional field-based ecological and evolutionary research. The link between biogeography and diversification still remains narrative and a comprehensive approach is necessary to establish how diversification was triggered by historical events.

“…Echimyidae is the most specious family within caviomorph rodents (Upham and Patterson, 2012); however, little is known about the biology of its species. Trinomys setosus (Desmarest, 1817) is known to be a ground dwelling echimyid, but the exact distribution within the endangered Brazilian Atlantic rainforest is unknown (MMA 2012).…”

ABSTRACT. Basal metabolic rate (BMR) represents the lowest level of metabolic activity capable to sustain homeostasis in an endotherm and is an important tool to compare metabolic rates of different species. Echimyidae is the most specious family within caviomorph rodents, however, little is known about the biology of its species, such as Trinomys setosus (Desmarest, 1817) and Clyomys bishopi (Ávila-Pires & Wutke, 1981), a ground and an underground dwelling echimyid, respectively. The ambient temperature and circadian effects on metabolic rate were evaluated through closed-system respirometry for these two species, as well as the circadian effects on CO 2 production and respiratory exchange ratio (RER). Trinomys setosus and C. bishopi showed the lowest metabolic rates (0.56 ± 0.02 mLO 2 .h , respectively) at 32 °C and during the light phase. Under laboratory conditions, T. setosus showed metabolic rate variation compatible with nocturnal activity, whereas C. bishopi activity cycle remains unclear. Both species showed BMR lower than expected by allometric regressions for rodents.
