Coltriciella minuscula sp. nov. is described and illustrated from a specimen collected on Pinus merkusii from Bogor, Indonesia. This species is characterized by the size of its basidiocarp up to 4 mm in diam, with long hair on the stipe and with ornamented spores. Both morphological distinctiveness and phylogenetic separation based upon analyses of nrDNA ITS sequences support the establishment of this new species. Morphological dissimilarities between C. minuscula and closely related species are discussed. 相似文献

The successful modelling of the structure of two hydrated calcium-rich natural zeolites is described, showing how modelling can reproduce their complex structure, in excellent agreement with experiment. Furthermore, we demonstrate how such methods are able to determine the preferred Al ordering in the mineral Goosecreekite. The dehydration behaviour of Goosecreekite is also predicted. The interatomic potentials for water, evaluated here, are found to be robust and transferable to zeolitic materials. 相似文献

The Asian songbird crisis which is currently unfolding in Southeast Asia has seen multiple bird taxa go extinct in the wild and even more slip into regional or local extinction over the span of only a few years. The hill mynas Gracula spp. are among its main victims, encompassing the Critically Endangered Nias Hill Myna Gracula [religiosa] robusta and other endangered populations across the West Sumatran Archipelago. Hill mynas are known to be present throughout this island chain but the taxonomic relationships of West Sumatran Gracula populations remain poorly understood. We hypothesized that the unique history of this island chain may have given rise to multiple distinct insular forms. Here we use genome‐wide DNA data in concert with morphological analyses to investigate the evolutionary distinctness of these taxa. Our results identify one taxon that is surprisingly distinct despite lacking recognition in most classifications, the ‘Simeulue Hill Myna’ (taxon miotera), and a range extension of the Nias Hill Myna. Despite their lack of recognition, Simeulue Hill Mynas are genomically and morphologically as unique as their Nias counterpart, in accordance with the lack of glacial land bridges between the island of Simeulue and mainland Sumatra. Simeulue Hill Mynas went extinct in the wild sometime within the last 2–3 years, and the rescue of the last captive individuals should now be the highest priority. 相似文献

The Indonesian island of Sulawesi, a globally important hotspot of avian endemism, has been relatively poorly studied ornithologically, to the extent that several new bird species from the region have been described to science only recently, and others have been observed and photographed, but never before collected or named to science. One of these is a new species of Muscicapa flycatcher that has been observed on several occasions since 1997. We collected two specimens in Central Sulawesi in 2012, and based on a combination of morphological, vocal and genetic characters, we describe the new species herein, more than 15 years after the first observations. The new species is superficially similar to the highly migratory, boreal-breeding Gray-streaked Flycatcher Muscicapa griseisticta, which winters in Sulawesi; however, the new species differs strongly from M. griseisticta in several morphological characters, song, and mtDNA. Based on mtDNA, the new species is only distantly related to M. griseisticta, instead being a member of the M. dauurica clade. The new species is evidently widely distributed in lowland and submontane forest throughout Sulawesi. This wide distribution coupled with the species'' apparent tolerance of disturbed habitats suggests it is not currently threatened with extinction. 相似文献

The effects of a mud snail, Cipangopaludina chinensis laeta (Martens) (Architaenioglossa: Viviparidae), on terrestrial arthropods through rice plant development in a paddy field were investigated in 2013 and 2014 by a field experiment. There were no significant differences between treatments in the abundance of aquatic organisms, which comprised several functional feeding groups in both years. The presence of mud snails did not significantly affect plant height and soil plant analysis development values, either, except in June 2014, when tiller number and biomass of the rice plants tended to be larger in plots with snails versus those without. Significantly higher abundances of terrestrial organisms, including phytophagous pest insects and other insects, but not natural enemies of the pest insects, occurred in plots with snails. As shown by principal component analysis, the community structure of the terrestrial organisms was significantly different between the two treatments in both years. The results of this study indicate that mud snails play an important role in the paddy field ecosystem, in which they influence the biomass production of rice plants and the abundance of organisms in terrestrial ecosystems through direct and indirect interactions at different trophic levels. 相似文献

Industrial timber plantations severely impact biodiversity in Southeast Asia. Forest fragments survive within plantations, but their conservation value in highly deforested landscapes in Southeast Asia is poorly understood. In this study, we compared bird assemblages in acacia plantations and fragmented forests in South Sumatra to evaluate each habitat’s potential conservation value. To clarify the impact of habitat change, we also analyzed the response of feeding guild composition. Five habitat types were studied: large logged forest (LLF), burnt logged forest (BLF), remnant logged forest (RLF), 4-year-old acacia plantation (AP4), and 1-year-old acacia plantation (AP1). Estimated species richness (Chao 2) was highest in LLF then AP4 and BLF, while AP1 and RLF had lower estimated species richness. Community composition was roughly divided into two groups by non-metric multidimensional scaling ordination: acacia plantation and logged forest. Sallying substrate-gleaning insectivores, such as drongos, broadbills, and some flycatchers, were restricted to LLF, whereas acacia plantation hosted many terrestrial frugivores, such as doves. Although fragmented forests in our study site lacked several common tropical forest species, these fragments provide an important habitat for some sallying and terrestrial insectivores. A network of small riparian remnant forests could be a complementary habitat for some species, while the conservation value of burnt forest might be low. In conclusion, the highly fragmented forests in plantations are suboptimal habitats for birds but are still very important, because large primary forest blocks have been nearly lost in the surrounding landscape. 相似文献
