The global diversification of songbirds (Oscines) and the build-up of the Sino-Himalayan diversity hotspot

引用

Chinese Birds 2013年第2期4卷 132-143页

作者： Jon FJELDS 丹麦自然历史博物馆宏观生态进化及气候中心

Over the last decade, molecular phylogenetic studies have provided the foundation for a comprehensive analysis of the global diversification of songbirds (Oscines), which comprise nearly half of all the birds of the world. By comparing the spatial distribution of species representing basal and terminal root-path groups, this paper provides graphical illustrations of the global pattern of diversification for the major songbird clades. The worldwide expansion of songbirds started as an island radiation in the area where New Guinea is now located, but the mountains of southern China represent a principal center for more recent diversification. The paper suggests priorities and perspectives for further research aiming to understand what determines the variation in biodiversity on different spatial scales.

Novel insights into the historical biogeography of the streak-breasted scimitar babbler complex （Aves： Timaliidae： Pomatorhinus ruficollis complex）

引用

Current Zoology 2015年第5期61卷 910-921页

作者： Sushma REDDY Arpad S. NYARI Biology Department Loyola University Chicago 1032 W Sheridan Road Chicago IL 60660 USA Department of Zoology Oklahoma State University 501 Life Sciences West Stillwater OK 74078 USA

The Streak-breasted Scimitar Babblers of the Pomatorhinus ruficollis species complex are found in most of the forested habitats across southern and eastern Asia. The diversification history of this group is obscured by high plumage variation across populations and conflicting genetic signal across loci. We combined genetic and geographic data from several recent studies to investigate how these species diversified across China using both phylogenetic and ecological niche modeling analyses. These two lines of evidence are consistent in showing that two well-sampled species, P. reconditus and P. nigrostellatus, in central and southern China respectively, likely experienced a history of isolation and expansion as suitable habitat contracted during the last interglacial and expanded in patchy extent during the glacial maximum. The genetic analysis showed that populations of P. nigrostellatus on Hainan Island are very similar to the ones in nearby mainland southern China. We recovered two well-supported clades within P. reconditus that were not geographically structured with both containing individuals from the same localities across central China. This phylogenetic result corresponded to the ecological niche models that showed expansion from refugia since the last interglacial. This study illustrates the value of using an integrative approach and detailed geographic sampling to help understand the recent diversification of birds in China [Current Zoology 61 （5）： 910-921, 2015].

Riparian and Riverine Wildlife Response to a Newly Created Bridge Crossing

引用

Natural Resources 2012年第4期3卷 213-228页

作者： Joshua A. Vance Norse B. Angus James T. Anderson West Virginia Department of Transportation Division of Highways Charleston USA West Virginia University Division of Forestry and Natural Resources Morgantown USA

Construction of man-made objects such as roads and bridges can influence wildlife presence and abundance. We investtigated waterbirds, songbirds, anurans, turtles, small mammals, and furbearers along the Ohio River, WV, at a new bridge crossing, a 45-year old bridge, and 1 or 2 islands with no bridge and at 3 distances from the bridge or center point at each site (0 m,100 m, and300 m). We sampled 19 waterbird, 60 songbird, 7 anuran, 5 turtle, 9 small mammal, and 4 furbearer species. Great blue heron (Ardea herodias) abundances were greater at the site with no bridge. Songbird composition differed among sites and between transects under and away from the bridge with higher abundances or association of rock pigeon (Columba livia) and cliff swallow (Petrochelidon pyrrhonota) under the bridges and lower abundances ofCarolinawren (Thryothorus ludovicianus) and common yellowthroat (Geothlypis trichas) under the bridges. Total small mammal abundance, diversity, and richness were lower under the new bridge compared to other sites and distances. We conclude that overall the new bridge is causing minimal relative abundance impacts to wildlife. However, great blue heron abundance may be altered due to noise and activity from the presence of the bridge and minor short-term impacts to some songbirds and small mammals directly under the bridge in the form of habitat conversion, fragmentation, and loss due to removal of vegetation is apparent.
