1Effects of forest fragmentation on nocturnal Asian birds:A case study from Xishuangbanna,China显示文摘Owls have the potential to be keystone species for conservation in fragmented landscapes, as the absence of these predators could profoundly change community structure. Yet few studies have examined how whole communities of owls respond to fragmentation, especially in the tropics. When evaluating the effect of factors related to fragmentation, such as fragment area and distance to the edge, on these birds, it is also important in heterogeneous landscapes to ask how ‘location factors' such as the topography, vegetation and soil of the fragment predict their persistence. In Xishuangbanna, southwest China, we established 43 transects(200 m×60 m) within 20 forest fragments to sample nocturnal birds, both visually and aurally. We used a multimodel inference approach to identify the factors that influence owl species richness, and generalized linear mixed models to predict the occurrence probabilities of each species. We found that fragmentation factors dominated location factors, with larger fragments having more species, and four of eight species were significantly more likely to occur in large fragments. Given the potential importance of these birds on regulating small mammal and other animal populations, and thus indirectly affecting seed dispersal, we suggest further protection of large fragments and programs to increase their connectivity to the remaining smaller fragments.Salindra K.DAYANANDA Eben GOODALE Myung-bok LEE Jia-Jia LIU Christos MAMMIDES Bonifacio O.PASION Rui-Chang QUAN J.W.Ferry SLIK Rachakonda SREEKAR Kyle W.TOMLINSON Mika YASUDA 2016Zoological Research2016,37,3:1
2Phylogeography and introgression between Pinus kesiya and Pinus yunnanensis in Southeast Asia显示文摘Southeast Asia(SEA)has seen strong climatic oscillations and fluctuations in sea levels during the Quaternary.The impact of past climate changes on the evolution and distribution of local flora in SEA is still poorly understood.Here we aim to infer how the Quaternary climate change affects the evolutionary process and range shifts in two pine species.We investigated the population genetic structure and diversity using cytoplasmic DNA markers,and performed ecological niche modeling to reconstruct the species past distribution and to project range shift under future climates.We found substantial gene flow across the continuous distribution of the subtropical Pinus yunnanensis.In contrast,the tropical Pinus kesiya showed a strong population structure in accordance with its disjunct distribution across montane islands in Indochina and the Philippines.A broad hybrid zone of the two species occurs in southern Yunnan.Asymmetric introgression from the two species was detected in this zone with dominant mitochondrial gene flow from P.yunnanensis and chloroplast gene flow from P.kesiya.The observed population structure suggests a typical postglaciation expansion in P.yunnanensis,and a glacial expansion and interglacial contraction in P.kesiya.Ecological niche modeling supports the inferred demographic history and predicts a decrease in range size for P.kesiya under future climates.Our results suggest that tropical pine species in SEA have undergone evolutionary trajectories different from high latitude species related to their Quaternary climate histories.We also illustrate the need for urgent conservation actions in this fragmented landscape.Jie Gao Kyle W.Tomlinson Wei Zhao Baosheng Wang Ralph Sedricke Lapuz Jing-Xin Liu Bonifacio O.Pasion Bach T.Hai Souvick Chanthayod Jin Chen Xiao-Ru Wang 2024Journal of Systematics and Evolution2024,62,1:0
