Pattern of genetic differentiation of an incipient speciation process: The case of the high Andean killifish Orestias.
Published 2017-01-01“…The endemic fish Orestias (Cyprinodontidae) represents a good model to observe the genetic differentiation that characterizes an incipient speciation process in allopatry since the morphospecies described inhabit a restricted geographic area, with present habitat fragmentation. The genetic diversity and population structure of four endemic morphospecies of Orestias (Cyprinodontidae) found in the Lauca National Park (LNP) analyzed with mitochondrial markers (Control Region) and eight microsatellites, revealed the existence of genetic groups that matches the fragmentation of these systems. …”

Altered natal dispersal at the range periphery: The role of behavior, resources, and maternal condition
Published 2017-01-01“…We test for the influence of proximate factors and ultimate drivers of natal dispersal: habitat fragmentation, local population density, individual behavior traits, inbreeding avoidance, competition for mates, and competition for resources, allowing us to better understand altered natal dispersal patterns at the periphery of a species’ range. …”

eEcoLiDAR, eScience infrastructure for ecological applications of LiDAR point clouds: reconstructing the 3D ecosystem structure for animals at regional to continental scales
Published 2017-07-01“…This will allow novel insights into the hierarchical structure of animal-habitat associations, into why animal populations decline, and how they respond to habitat fragmentation and ongoing land use change. The processing of these massive amounts of LiDAR point cloud data will be achieved by developing a generic interactive eScience environment with multi-scale object-based image analysis (OBIA) and interpretation of LiDAR point clouds, including data storage, scalable computing, tools for machine learning and visualisation (feature selection, annotation/segmentation, object classification, and evaluation), and a PostGIS spatial database. …”

Genetic diversity and structure analysis of the endangered plant species Horsfieldia hainanensis Merr. in China
Published 2018-01-01“…Collectively, we speculated that habitat fragmentation and disturbance from human activities could be considered the main reasons for the endangerment of H. hainanensis, and we propose in situ conservation for the existing natural H. hainanensis populations, especially at Mengtun, Niandou and Tongbiguan, where the genetic diversity is relatively high.…”
