Potential distribution models from two highly endemic species of subterranean rodents of Argentina: which environmental variables have better performance in highly specialized species?

Genetic footprints of Quaternary climatic fluctuations on the endangered Tuco-tuco-das-dunas (Ctenomys flamarioni)

“…Given the high dependence of tuco-tucos on the availability of soils with high sand content (e.g. Austrich et al 2021; Galiano and Kubiak 2021) and therefore the distribution of C. flamarioni being limited to dune ridges of the Coastal Plain of Southern Brazil, the geomorphological evolution of the coastal plain may have played a central role in genetic patterns observed. During the Late Quaternary, 4 different events involving sedimentary processes were associated with transgressive–regressive fluctuations of sea level and contributed to shaping the current landscape of the Coastal Plain (Tomazelli and Villwock 2005).…”

“…However, differences found between the regression analyses using paleoclimate stability and niche suitability may be related to the bioclimatic variables on which species distribution models were estimated since these may not limit the distribution of subterranean species to the degree that they limit the distribution of aboveground species. Certainly, using variables related to soil and vegetation would be important to be considered for future niche modeling studies of subterranean species such as tuco-tucos (Austrich et al 2021).…”

“…Our results revealed a general pattern of low genetic diversity for the current phylogenetic lineages of C. flamarioni, with slightly higher levels in Central-North populations and a strong decrease in genetic variability observed for populations in the South. Given the high dependence of tuco-tucos on the availability of soils with high sand content (e.g Austrich et al 2021;Galiano and Kubiak 2021). and therefore the distribution of C. flamarioni being limited to dune ridges of the Coastal Plain of Southern Brazil, the geomorphological evolution of the coastal plain may have played a central role in genetic patterns observed.…”

Global climate change effect on AsianMus musculus; Implication from last glacial maximum to the end of the 21stcentury

“…Previous studies have applied SDMs to assess the impacts of climate change on various rodent species (Cameron & Scheel 2001;Meserve et al 2011;Jiang et al 2013;Bean et al 2014;Latinne et al 2015;Gutiérrez-Tapia and Palma 2016;Austrich et al 2021;Shiels et al 2022;Wan et al 2022). However, there is a notable gap in our understanding concerning the impacts of climate change on Mus musculus, specifically.…”

“…These models utilize species presence points and climatic data to predict species distributions and have been successfully employed in various contexts, including identifying future species distribution, climatic refugia, changes in distribution, and evaluating the effectiveness of protected areas under current and future climates (Ashrafzadeh et al 2019; Hoveka et al 2020; Prieto-Torres et al 2020; Ramírez-Albores et al 2020; Petersen et al 2021; Sierra-Morales et al 2021; Vaissi 2021). Previous studies have applied SDMs to assess the impacts of climate change on various rodent species (Cameron & Scheel 2001; Meserve et al 2011; Jiang et al 2013; Bean et al 2014; Latinne et al 2015; Gutiérrez-Tapia and Palma 2016; Austrich et al 2021; Shiels et al 2022; Wan et al 2022).
