“…This makes both giant flying squirrel subspecies suitable for this study. Hyper‐variable mtDNA control region sequences were used successfully to evaluate genetic structures of other squirrel populations (Barratt et al ., 1999; Oshida et al ., 2001, 2004a, 2006), making them useful molecular markers to resolve phylogeographical characteristics of P. alborufus lena and P. philippensis grandis .…”

To test the association between Pleistocene forest dynamics relative to elevation and the population dynamics of arboreal small mammals, we examined the phylogeographical predictions for the genetic structure of the red and white giant flying squirrel (Petaurista alborufus lena) and the Indian giant flying squirrel (P. philippensis grandis) using complete mitochondrial control region sequences. Both giant flying squirrels are endemic subspecies to Taiwan and are sympatric in much of their range. In the phylogenetic analyses, we included 35 specimens of P. alborufus lena collected from 20 localities and five specimens with unknown sampling localities. Also, we phylogenetically examined 32 specimens of P. philippensis grandis from 18 localities and three specimens with unknown sampling localities. We identified 36 haplotypes of P. alborufus lena and 33 haplotypes of P. philippensis grandis. Although we did not recognize major phylogroups, we found several minor phylogroups in both subspecies, suggesting similar evolutionary histories. Phylogeographical and demographic tests showed distributions of these two subspecies expanded into coniferous and mixed forests that developed during glaciation in Taiwan's lowlands and middle lands. This suggests that these two Petaurista subspecies shifted elevation from mountainous areas to lowlands during glaciation.

Squirrels have been traded in the pet market for several decades, and numerous species have established in the wild. The Asiatic species Callosciurus erythraeus and Callosciurus finlaysonii have been introduced into other parts of Asia, in Europe and South America. In this study, (1) we conducted a genetic characterization of C. erythraeus introduced into Argentina and compared them with native and introduced populations in Asia, and (2) we analyzed genetic variation among the four invasion foci in Argentina in order to corroborate that the pathway of invasion was a single introduction event in the country and subsequent translocations. We analyzed mitochondrial (cytochrome b, Cyt b; cytochrome oxidase c subunit I, COI and D-loop) and nuclear (recombination activating gene I, RAGI) DNA markers using the classical method (DNA barcoding gap analysis) and also the Automatic Barcode Gap Discovery method (ABGD). The markers D-loop, COI, and RAG1 indicated that the introduced squirrels from the different invasion foci formed a monophyletic group that, together with only one haplotype for the D-loop and COI markers, supported the hypothesis of one introduction event into Argentina followed by subsequent translocations. Unexpectedly, sequences from squirrels captured in Argentina were more related to C. finlaysonii than to C. erythraeus for D-loop and Cyt b markers. However, intraspecific variation among sequences of C. erythraeus belonging to different subspecies or collected in different regions was large and comparable with the distance to the sequences from Argentina. The ABGD method also indicated large genetic variability within C. erythraeus and close proximity between squirrels from Argentina and C. finlaysonii. The complex taxonomy of Callosciurus, as occurs with the sister species C. erythraeus and C. finlaysonii, requires a thorough systematic revision. A simultaneous analysis of diagnostic morphological characters and genetic markers is needed and will provide new insight regarding the worldwide invasion of Asiatic squirrels.
