“…The genetic separation observed generally agrees with existing biogeographical demarcations for the region (de Bruyn et al 2005;Hughes et al 2003Hughes et al , 2011Khan et al 2010;Woodruff and Turner 2009) system (Heaney 1991;Morley 2000;Gathorne-Hardy et al 2002). At this time, large areas of the peninsula emerged and connected many present-day islands.…”

Taxonomic implications of geographical variation in Rhinolophus affinis (Chiroptera: Rhinolophidae) in mainland Southeast Asia

Background: Rhinolophus affinis sensu lato is distributed throughout Southeast Asia. The taxonomic status of forms attributed to the species is unclear due to the limited sample size with incomplete datasets and the taxa have high variation in morphology and echolocation call frequency. The aim of the study was to evaluate the distribution and taxonomic status of the subspecific forms of R. affinis in mainland Southeast Asia using large sample size with multiple datasets, including morphological, acoustic, and genetic data, both to elucidate taxonomic relationships and to test for congruence between these datasets. Results: Three morphological forms were confirmed within the region; two concur with previously recognized taxa, namely R. affinis macrurus and R. affinis superans, and are strongly supported by morphological and genetic data. The third form is morphologically distinct, but its taxonomic status remains unclear. It is probable that this third form represents a distinct taxonomic entity; however, more data are required to confirm this. R. a. macrurus is known from the north of peninsular Thailand, Cambodia, Myanmar, Laos, and Vietnam (Indochinese subregion); R. a. superans is found throughout the Thai-Malay Peninsula (Sundaic subregion); whilst the third form is presently known from east central Myanmar (Shan state) and lower northern Vietnam (Nghe An Province).

The genetic legacy of lower sea levels: does the confluence of rivers during the last glacial maximum explain the contemporary distribution of a primary freshwater fish (Pseudobarbus burchelli, Cyprinidae) across isolated river systems?

The primary freshwater fish Pseudobarbus burchelli (Smith 1841) occurs across four presently isolated river systems in the south-western cape floristic region of South Africa. Mitochondrial DNA cytochrome b (701 base pairs) and control region (601 base pairs) genes were sequenced to assess the evolutionary history of P. burchelli and evaluate the role of climatic and landscape changes in shaping patterns of genetic variation in this species. We identified three historically isolated lineages in P. burchelli: a widespread lineage that occurs across three isolated river systems and two geographically restricted lineages. The results were evaluated against predictions of the confluence of river systems during low sea levels of the last glacial maximum. Occurrence of the widespread Breede lineage in the Duiwenhoks River system is consistent with reconstructed palaeoriver systems. However, the occurrence of this lineage in the Goukou river system that formed part of the eastern Gourits-Goukou palaeoriver system can only be explained by translocation or a recent river capture or episodic inundation of low drainage divides. Extreme ecological gradients or the potential presence of instream physical barriers could have prevented an exchange of lineages between the Breede and Heuningnes river systems.

“…Intraspecific variation in body size and iris color noted by Matsui et al (1999) was partially confirmed by us, but these populations did not exhibit significant genetic differentiation between them. Populations from the southern and northern Isthmus Kra occurred in a well-known faunal and floral boundary in Sundaland (e.g., Tougard, 2001;De Bruyn et al, 2005). Leptobrachium sp.…”

“…Subsequent intraspecific divergence in L. smithi was estimated to have begun in the early Pliocene. The Isthmus of Kra, peninsular Thailand, is usually noted as a major biogeographical transition zone (e.g., Tougard, 2001;De Bruyn et al, 2005), and it might have also affected the evolution of Leptobrachium. However, the specific date(s) of the disjunction is (are) not clear and simply estimated to have occurred as a result of a Neogene (<23 MYBP) marine transgression.…”
