Koenigia hedbergii, a new and distinct species collected from the Shennongjia National Nature Reserve in the Northwest of Hubei Province (central China) is described and illustrated. The new species can be easily distinguished from other Koenigia species by its leaves lanceolate or lanceolate-ovate each showing 6-11 pairs of lateral veins and with distinct undulate margins, by its ocreae glabrous but sparsely puberulent at the bases, and achenes sharply trigonous with three pronouncedly keeled edges. A morphological comparison among the new species and the related ones, K. Nepalensis and K. Pilosa, is presented. The Koenigia-type pollen grains of the the new species were also observed and described. © 2016 Magnolia Press.

The snub-nosed monkey genus Rhinopithecus includes five closely related species distributed across altitudinal gradients from 800 to 4,500 m. Rhinopithecus bieti, Rhinopithecus roxellana, and Rhinopithecus strykeri inhabit high-altitude habitats, whereas Rhinopithecus brelichi and Rhinopithecus avunculus inhabit lowland regions. We report the de novo whole-genome sequence of R. bieti and genomic sequences for the four other species. Eight shared substitutions were found in six genes related to lung function, DNA repair, and angiogenesis in the high-altitude snub-nosed monkeys. Functional assays showed that the high-altitude variant of CDT1 (Ala537Val) renders cells more resistant to UV irradiation, and the high-altitude variants of RNASE4 (Asn89Lys and Thr128Ile) confer enhanced ability to induce endothelial tube formation in vitro. Genomic scans in the R. bieti and R. roxellana populations identified signatures of selection between and within populations at genes involved in functions relevant to high-altitude adaptation. These results provide valuable insights into the adaptation to high altitude in the snub-nosed monkeys.

To explore the litterfall and their seasonal dynamics of the four typical forests along the altitudinal gradient in Mt. Shennongjia, Hubei. We measured litterfall of Evergreen broad-leaved forest (EBF), Mixed evergreen and deciduous broad-leaved forest (MF), Deciduous broad-leaved forest (DBF), and sub-alpine coniferous forest (CF) in Shennongjia. Litterfall collection was conducted monthly from September 2009 to January 2011. The result showed that the total annual litterfall of the four typical forests along the altitudinal gradient in Mt. Shennongjia was increased and then decreased along the altitude. The annual amounts of EBF was 6 807. 97 kg/hm2, MF 7 118. 14 kg/hm2, DBF 6 975. 2 kg/hm2 and CF 4 250.67 kg/hm2. The seasonal dynamics of litterfall iccurred two peaks during the periods from April to May and November annually. The returns of N from the littlefall of four forests along the elevation gradients were 132. 06, 162. 29, 157. 12 and 185.77 kg/hm2, and that of P was 4. 62, 4. 39, 8. 24 and 4. 15 kg/hm2.

The diet of Rhinopithecus roxellana is characterized by lichens, which are available year-round and an uncommon food source for nonhuman primates, supplemented by seasonal plant foods. We present the first study of foods eaten by R. roxellana in relation to nutritional chemistry in Shennongjia National Nature Reserve, Hubei Province, China. We analyzed the nutrients (crude protein, crude fat, and water soluble carbohydrate [WSC]) and feeding deterrents (crude fiber, condensed tannin [CT], and total phenolic [TP]) of 111 parts from 53 plant species and of 6 lichen species. Results showed that lichens were a good choice for R. roxellana living in habitats with limited and seasonally available plant foods. They contained higher concentrations of WSC than foliage, fat concentrations equivalent to those in plant parts (except fruits/seeds), and lower concentrations of fiber than mature leaves, flowers, and fruits. Although lichens were lower in protein than plant parts (except fruits), the monkeys could likely meet their protein requirement by eating seasonal plant foods rich in protein, including foliage, flowers, buds, and seeds. The monkeys were not observed to select foliage higher in protein, but appeared to select mature leaves higher in WSC and lower in fiber. Fruits were a good source of WSC and fat, and seeds were a good source of fat. Neither CT nor TP content showed negative effects on the selection of mature leaves or lichens. © 2013 Wiley Periodicals, Inc.

Most Old World monkeys show male-biased dispersal. We present the first systematic data on male dispersal in a provisioned multilevel group of Rhinopithecus roxellana, based on 4.5 years of field observations in Shennongjia National Nature Reserve, China. We evaluated both ultimate (inbreeding avoidance and male mating competition) and proximate (food availability and predation risk) factors influencing male dispersal. The focal group contained 34-53 individuals, in 3-4 one-male units (OMUs) and 1 all-male unit (AMU). We observed 37 dispersal events involving 10 of 11 adults, 7 of 8 subadults, and 7 of 15 juveniles. Most interunit transfers within the focal group occurred around the months of mating season. Adult males competed for the leader positions of OMUs mainly through aggressive takeovers, and young males transferred from the OMUs to the AMU at the median age of 41 months, forced out by leader males. No young males older than 4 years remained in natal or non-natal OMUs. The male mating competition hypothesis was supported. The young males emigrated voluntarily from the focal group at the average age of 58.6 months, and no young emigrating male was observed to return, suggesting inbreeding avoidance also played a role in the dispersal of young males. Most emigration/immigration events were parallel dispersal and occurred during intergroup encounters, suggesting increased predation risk during the dispersal period. Males were more likely to emigrate/immigrate during the months when preferred foods were most available. We compared the dispersal patterns in R. roxellana with those in gelada baboons and hamadryas baboons, both living in multilevel societies. Similar to R. roxellana, young male geladas disperse at puberty, but they may return and breed in their natal groups. Males in hamadryas also disperse, but much less commonly than in R. roxellana. Provisioning may have influenced results, and confirming studies on unprovisioned groups would be valuable. © 2011 Wiley Periodicals, Inc.
