“…On the other hand, our region‐wide analysis of evolutionary history corroborated deep divergences among populations in the three geographical regions of Singapore (including Johor), Borneo, and Palawan, with the latter emerging as exceptionally genetically distinct (Oliveros and Moyle 2010; Lim et al. 2011). Our findings have important implications for the long‐term population persistence of local and regional olive‐winged bulbul populations as well as the ecosystem services they provide.…”

“…However, genetic work in this region has mostly focused on large‐scale relationships, such as phylogeography (Lim et al. 2011) and phylogenetic relationships (Oliveros and Moyle 2010). Many of these studies include only a few species from the Old World tropics and do not focus on any particular species (e.g., Morales and Melnick 1998; Moyle and Marks 2006; Lohman et al.…”

With increasing urbanization, urban‐fragmented landscapes are becoming more and more prevalent worldwide. Such fragmentation may lead to small, isolated populations that face great threats from genetic factors that affect even avian species with high dispersal propensities. Yet few studies have investigated the population genetics of species living within urban‐fragmented landscapes in the Old World tropics, in spite of the high levels of deforestation and fragmentation within this region. We investigated the evolutionary history and population genetics of the olive‐winged bulbul (Pycnonotus plumosus) in Singapore, a highly urbanized island which retains <5% of its original forest cover in fragments. Combining our own collected and sequenced samples with those from the literature, we conducted phylogenetic and population genetic analyses. We revealed high genetic diversity, evidence for population expansion, and potential presence of pronounced gene flow across the population in Singapore. This suggests increased chances of long‐term persistence for the olive‐winged bulbul and the ecosystem services it provides within this landscape.

“…The present-day insular nature of this region is unrepresentative of the historical situation because most of the time the area formed a single landmass as a result of lowered sea levels associated with global cooling events (2)(3)(4)(5). Despite this long history of land connections, there exists a marked biogeographic boundary between western (Malay Peninsula and Sumatra) and eastern (Borneo) Sundaland (3,5,6). These differences have been explained by a hypothesized north-south-oriented savanna corridor through the center of Sundaland that blocked dispersal of wet forest species (7)(8)(9)(10)(11)(12)(13).…”

The marked biogeographic difference between western (Malay Peninsula and Sumatra) and eastern (Borneo) Sundaland is surprising given the long time that these areas have formed a single landmass. A dispersal barrier in the form of a dry savanna corridor during glacial maxima has been proposed to explain this disparity. However, the short duration of these dry savanna conditions make it an unlikely sole cause for the biogeographic pattern. An additional explanation might be related to the coarse sandy soils of central Sundaland. To test these two nonexclusive hypotheses, we performed a floristic cluster analysis based on 111 tree inventories from Peninsular Malaysia, Sumatra, and Borneo. We then identified the indicator genera for clusters that crossed the central Sundaland biogeographic boundary and those that did not cross and tested whether drought and coarse-soil tolerance of the indicator genera differed between them. We found 11 terminal floristic clusters, 10 occurring in Borneo, 5 in Sumatra, and 3 in Peninsular Malaysia. Indicator taxa of clusters that occurred across Sundaland had significantly higher coarse-soil tolerance than did those from clusters that occurred east or west of central Sundaland. For drought tolerance, no such pattern was detected. These results strongly suggest that exposed sandy sea-bed soils acted as a dispersal barrier in central Sundaland. However, we could not confirm the presence of a savanna corridor. This finding makes it clear that proposed biogeographic explanations for plant and animal distributions within Sundaland, including possible migration routes for early humans, need to be reevaluated.climate change | human migration | plant distribution | sea-level change

“…Papers by Carstens, Richards, and Knowles (Carstens and Richards 2007;Knowles et al 2007;Richards et al 2007) presented the basis for new and more synthetic ideas and approaches. This promise is now translating into rich research results, with many exciting and novel papers appearing each month (Chan et al 2011;Lim et al 2011). Such rapid methodological evolution suggests a rich future for such studies, in which deep insights into past geographies of species become available.…”

Peterson, A. T., and B. S. Lieberman. 2012. Species' geographic distributions through time: Playing catchup with changing climates. Evolution: Education and Outreach (2 March 2012), pp. 1-13, Publisher's official version: http://dx.doi.org/10.1007/s12052-012-0385-2 . Open Access version: http://kuscholarworks.ku.edu/dspace/. Keywords:Paleontology , Neontology, Geographic distribution, Climate change Abstract:Species' ranges are often treated as a rather fixed characteristic, rather than a fluid, ever-changing manifestation of their ecological requirements and dispersal abilities. Paleontologists generally have had a more flexible point of view on this issue than neontologists, but each perspective can improve by appreciating the other. Here, we provide an overview of paleontological and neontological perspectives on species' geographic distributions, focusing on what can be learned about historical variations in distributions. The cross-disciplinary view, we hope, offers some novel perspectives on species-level biogeography.
