Genetic analyses favour an ancient and natural origin of elephants on Borneo
Sharma, Reeta; Goossens, Benoit; Heller, Rasmus; Rasteiro, Rita; Othman, Nurzhafarina; Bruford, Michael W.; Chikhi, LounèsThe origin of the elephant on the island of Borneo remains elusive. Research has suggested two alternative hypotheses: the Bornean elephant stems either from a recent introduction in the 17th century or from an ancient colonization several hundreds of thousands years ago. Lack of elephant fossils has been interpreted as evidence for a very recent introduction, whereas mtDNA divergence from other Asian elephants...
Generation of SNP datasets for orangutan population genomics using improved red...
Greminger, Maja P; Stölting, Kai N; Nater, Alexander; Goossens, Benoit; Arora, Natasha; Bruggmann, Rémy; Patrignani, Andrea; Nussberger, BeatriceHigh-throughput sequencing has opened up exciting possibilities in population and conservation genetics by enabling the assessment of genetic variation at genome-wide scales. One approach to reduce genome complexity, i.e. investigating only parts of the genome, is reduced-representation library (RRL) sequencing. Like similar approaches, RRL sequencing reduces ascertainment bias due to simultaneous discovery and...
Effective Population Size Dynamics and the Demographic Collapse of Bornean Oran...
Sharma, Reeta; Arora, Natasha; Goossens, Benoit; Nater, Alexander; Morf, Nadja; Salmona, Jordi; Bruford, Michael W.; Van Schaik, Carel P.Bornean orang-utans experienced a major demographic decline and local extirpations during the Pleistocene and Holocene due to climate change, the arrival of modern humans, of farmers and recent commercially-driven habitat loss and fragmentation. The recent loss of habitat and its dramatic fragmentation has affected the patterns of genetic variability and differentiation among the remaining populations and incre...
Two Different High Throughput Sequencing Approaches Identify Thousands of De No...
Sharma, Reeta; Goossens, Benoit; Kun-Rodrigues, Célia; Teixeira, Tatiana; Othman, Nurzhafarina; Boone, Jason Q.; Jue, Nathaniel K.; Obergfell, CraigHigh throughput sequencing technologies are being applied to an increasing number of model species with a high-quality reference genome. The application and analyses of whole-genome sequence data in non-model species with no prior genomic information are currently under way. Recent sequencing technologies provide new opportunities for gathering genomic data in natural populations, laying the empirical foundatio...
