Tropical Southeast (SE) Asia harbors extraordinary species richness and in its entirety comprises four of the Earth's 34 biodiversity hotspots. Here, we examine assembly SE Asian biota through time space. We conduct meta-analyses geological, climatic, biological (including 61 phylogenetic) data sets to test which areas have been sources long-term diversity Asia, particularly pre-Miocene, Miocene, Plio-Pleistocene, whether respective dominated by situ diversification, immigration and/or emigration, or equilibrium dynamics. identify Borneo Indochina, particular, as major "evolutionary hotspots" for a diverse range fauna flora. Although most region's is result both accumulation immigrants within-area diversification subsequent emigration predominant signals characterizing Indochina Borneo's since at least early Miocene. In contrast, colonization events are comparatively rare from younger volcanically active emergent islands such Java, show increased levels events. Few dispersal were observed across biogeographic barrier Wallace's Line. Accelerated efforts conserve flora currently housing highest plant mammal richness, critically required.

Shifting seas: the impacts of Pleistocene sea‐level fluctuations on the evolution of tropical marine taxa

Journal of Biogeography, Год журнала: 2014, Номер 42(1), С. 25 - 38

Опубликована: Сен. 26, 2014

Abstract Aim Pleistocene glacial cycles reduced global sea level by up to 130 m below present levels. These changes had profound impacts on coastal marine life, including a reduction of habitable area, in ocean currents, and shifts water column thermal dynamics. We provide comprehensive review the impact sea‐level during tropical life set maps showing how coastlines worldwide changed periods low Location focused taxa within latitudes, with deeper coverage world's major coral reef biogeographical provinces. Methods examined recent historical literature that alluded effects fluctuations variety common clades. Data for shelf habitat area map construction were obtained from NOAA ETOPO 1 database, final manipulations carried out Adobe Illustrator CS 6. Results Drops led decrease available fragmented populations many taxa, potentially resulting high population genetic structuring. Habitable lows was as much 92% present‐day values some regions. Genetic evidence bottlenecks can be seen worldwide. Main conclusions seem linked worldwide, influenced connections among separated barriers are affected Despite decreased availability, very few species became extinct, several may have been formed due restrictions (and consequently larval) flow between regions now connected. A interdisciplinary studies significantly increased our understanding shaped landscape we see today.

Forest contraction in north equatorial Southeast Asia during the Last Glacial Period

Proceedings of the National Academy of Sciences, Год журнала: 2010, Номер 107(35), С. 15508 - 15511

Опубликована: Июль 26, 2010

Today, insular Southeast Asia is important for both its remarkably rich biodiversity and globally significant roles in atmospheric oceanic circulation. Despite the fundamental importance of environmental history diversity conservation, there little primary evidence concerning nature vegetation north equatorial during Last Glacial Period (LGP). As a result, even general distribution Maximum debated. Here we show, using stable carbon isotope composition ancient cave guano profiles, that was substantial forest contraction LGP on peninsular Malaysia Palawan, while rainforest maintained northern Borneo. These results directly support “refugia” hypotheses provide barriers likely reduced genetic mixing between Borneo Sumatra flora fauna. Moreover, it sheds light possible early human dispersal events.

Plio-Pleistocene sea level and temperature fluctuations in the northwestern Pacific promoted speciation in the globally-distributed flathead mullet Mugil cephalus

The study of speciation in the marine realm is challenging because apparent absence physical barriers to dispersal, which are one main drivers genetic diversity. Although phylogeographic studies using mitochondrial DNA (mtDNA) information often reveal significant heterogeneity within species, evolutionary significance such diversity difficult interpret with these markers. In northwestern (NW) Pacific, several have emphasised potential importance sea-level regression during most recent glaciations as a driver species. These failed, however, determine whether period isolation was long enough for divergence attain speciation. Among cosmopolitan estuarine-dependent fish Mugil cephalus represents an interesting case study. Several divergent allopatric mtDNA lineages been described this species worldwide, and three occur sympatry NW Pacific.Ten nuclear microsatellites were surveyed estimate level role fluctuation evolution Pacific M. cephalus.

Sundaland, a tropical hotspot of biodiversity comprising Borneo and Sumatra among other islands, the Malay Peninsula, shallow sea, has been subject to dramatic environmental processes. Thus, it presents an ideal opportunity investigate role mechanisms in shaping species distribution diversity. We investigated population structure underlying insular endemic, Bornean orangutan ( Pongo pygmaeus ). Phylogenetic reconstructions based on mtDNA sequences from 211 wild orangutans covering entire range indicate unexpectedly recent common ancestor 176 ka (95% highest posterior density, 72–322 ka), pointing Pleistocene refugium. High differentiation populations rare haplotype sharing is consistent with pattern strong female philopatry. This corroborated by isolation distance tests, which show significant correlation between divergence effect rivers as barriers for movement. Both frequency-based Bayesian clustering analyses using many 25 nuclear microsatellite loci revealed separation all populations, well small degree male-mediated gene flow. study highlights unique effects biological features evolutionary history orangutans, highly endangered particularly vulnerable future climate anthropogenic change endemic.

Comparative phylogeography of bamboo bats of the genus Tylonycteris (Chiroptera, Vespertilionidae) in Southeast Asia

European Journal of Taxonomy, Год журнала: 2017, Номер 274

Опубликована: Фев. 9, 2017

In Southeast Asia, bats of the genus Tylonycteris Peters, 1872 have traditionally been classified into two wide-ranging species, T. pachypus (Temminck, 1840) and robustula Thomas, 1915. Our comparative phylogeographic analyses based on mitochondrial seven nuclear genes, combined with our multivariate morphological analyses, show that these species actually represent cryptic complexes share a similar biogeographic history in three major regions, i.e., Sundaland, southern Indochina, northern Indochina. molecular dating estimates suggest Pleistocene climatic oscillations sea level changes repeatedly isolated ancestral populations spp. distant bamboo forest refugia. The indicate, however, complex were less affected by fragmentation mainland Asia than those complex. Accordingly, we propose several taxonomic within Tylonycteris: fulvida malayana are revalidated, new tonkinensis Tu, Csorba, Ruedi & Hassanin sp. nov., endemic to is described.
