Mitogenomic Analysis of Glirids (Gliridae) and Squirrels (Sciuridae) From Türkiye: Evolutionary and Taxonomic Implications Within the Suborder Sciuromorpha. [PDF]

open access: yesEcol Evol
This study presents mitogenomic analyses of three squirrel (Sciuridae) and three dormouse (Gliridae) species from Türkiye, uncovering significant phylogenetic and phylogeographic insights within the suborder Sciuromorpha. Phylogenetic analyses positioned Gliridae as the basal group within the suborder, and mitogenomic and CYTB data revealed distinct ...

Mapping endemic freshwater fish richness to identify high-priority areas for conservation: An ecoregion approach. [PDF]

open access: yesEcol Evol
Iran's freshwater ecosystems are home to 85 endemic fish species. By analyzing distribution records and using a generalized linear model, the researchers identified the Zagros Mountains as having the highest endemic fish richness, followed by a moderate level between the Zagros and Alborz Mountains.
