Data from: Comparative ecological and behavioral study of Macaca assamensis and M. mulatta in Shivapuri Nagarjun National Park, Nepal

Sunil Khatiwada, Pavan Kumar Paudel, Mukesh K Chalise & Hideshi Ogawa
Resource partitioning reduces resource competition between different species within the same habitat, promoting their coexistence. To understand how such species, co-adapt to reduce conflicts, we examined the behaviour of two primates, the Assamese macaque (Macaca assamensis) and the rhesus macaque (Macaca mulatta), from April 2017 to March 2018 in Sivapuri Nagarjun National Park (SNNP), Kathmandu Valley, Nepal. We performed 1,580 and 1,261 scan sessions on wild, multi-male/multi-female groups of Assamese and rhesus macaques, respectively, at...

Data from: Reproductive isolation in alpine gingers: how do co-existing Roscoea (R. purpurea and R. tumjensis) conserve species integrity?

Babu Ram Paudel, Martin Burd, Mani Shrestha, Adrian G. Dyer, Qingjun Li & Qing-Jun Li
Multiple barriers may contribute to reproductive isolation between closely related species. Understanding the relative strength of these barriers can illuminate the ecological factors that currently maintain species integrity and how these factors originally promoted speciation. Two Himalayan alpine gingers, Roscoea purpurea and R. tumjensis, occur sympatrically in central Nepal and have such similar morphology that it is not clear whether or how they maintain a distinct identity. Our quantitative measurements of the components of reproductive...

Tree-to-tree interactions slow down Himalayan treeline shifts as inferred from tree spatial patterns

Shalik Ram Sigdel, Eryuan Liang, Yafeng Wang, Binod Dawadi & Jesús Julio Camarero
Aim: The spatial patterns of tree populations reflect multiple ecological processes. However, little is known whether these patterns mediate responses to climate in marginal tree populations as those forming alpine treelines. Harsh conditions at these ecotones imply the existence of positive interactions which should lead to tree clustering. In fact, densification in response to climate warming is more widely reported than upward shifts in most treelines. This suggests that more intense tree-to-tree interactions could buffer...

Energy-water and seasonal variations in climate underlie the spatial distribution patterns of gymnosperms species richness in China

Bikram Pandey, Janak Khatiwada, Lin Zhang, Kaiwen Pan, Mohammed Dakhil, Qinli Xiong, Ram Yadav, Mohan Siwakoti, Akash Tariq, Olusanya Olatunji, Meta Justine, Xiaogang Wu, Xiaoming Sun, Ziyan Liao & Zebene Negesse
Studying the pattern of species richness is crucial in understanding the diversity and distribution of organisms in the earth. Climate and human influences are the major driving factors that directly influence the large-scale distributions of plant species, including gymnosperms. Understanding how gymnosperms respond to climate, topography, and human-induced changes is useful in predicting the impacts of global change. Here, we attempt to evaluate how climatic and human-induced processes could affect the spatial richness patterns of...

Data from: Ecological correlates of Himalayan musk deer Moschus leucogaster

Paras Bikram Singh, Pradip Saud, Kumar Mainali, Doug Cram, Arjun Thapa, Nar Bahadur Chhetri, Laxman P. Poudyal, Hem Sagar Baral, Zhigang Jiang & Douglas Cram
Himalayan musk deer (Moschus leucogaster; hereafter musk deer) are endangered as a result of poaching and habitat loss. The species is nocturnal, crepuscular and elusive, making direct observation of habitat use and behavior difficult. However, musk deer establish and repeatedly use the same latrines for defecation. To quantify musk deer habitat correlates, we used observational spatial data based on presence-absence of musk deer latrines, as well as a range of fine spatial-scale ecological covariates. To...

Data from: Population genomics of wild and laboratory zebrafish (Danio rerio)

Andrew R Whiteley, Anuradha Bhat, Emilia P Martins, Richard L Mayden, M Arunachalam, Silva Uusi-Heikkilä, A.T.A. Ahmed, Jiwan Shrestha, Matthew Clark, Derek Stemple & Louis Bernatchez
Understanding a wider range of genotype-phenotype associations can be achieved through ecological and evolutionary studies of traditional laboratory models. Here, we conducted the first large-scale geographic analysis of genetic variation within and among wild zebrafish (Danio rerio) populations occurring in Nepal, India, and Bangladesh and we genetically compared wild populations to several commonly used lab strains. We examined genetic variation at 1,832 polymorphic EST-based SNPs and the cytb mitochondrial gene in 13 wild populations and...

Data from: Flower colour and phylogeny along an altitudinal gradient in the Himalaya of Nepal

Mani Shrestha, Adrian Dyer, Prakash Bhattarai, Martin Burd & Adrian G. Dyer
1. Both the phylogenetic structure and trait composition of flowering plant communities may be expected to change with altitude. In particular, floral colours are thought to vary with altitude because Hymenoptera typically decline in importance as pollinators while Diptera and Lepidoptera become more important at higher elevations. Thus, ecological filtering among elevation zones and competitive processes among co-occurring species within zones could influence the floral chromatic cues present at low and high elevations. 2. We...

Examining the needle in the haystack: Evolutionary relationships in the mistletoe genus Loranthus Jacq. (Loranthaceae)

Daniel Nickrent, Huei-Jiun Su, Ruo-Zhu Lin, Mohan Prasad Devkota, Jer-Ming Hu & Gerhard Glatzel
The genus Loranthus Jacq. (Loranthaceae) consists of ca. nine Old World species distributed from eastern Asia to Europe. Loranthus, the type of the family, has had a complex taxonomic history that continues today, partly because most mistletoes in the family have resided in this genus. For this reason, there are over 1800 Loranthus species names, the vast majority of which are synonyms for mistletoes in other genera. The present work sampled representatives of nine species...

Estimating occupancy of Chinese pangolin (Manis pentadactyla) in a protected and non-protected area of Nepal

Sandhya Sharma, Hari Sharma, Chanda Chaulagain, Hem Katuwal & Jerrold Belant
Chinese pangolin is the world’s most heavily trafficked small mammal for luxury food and traditional medicine. Although their populations are declining worldwide, it is difficult to monitor their population status because of its rarity and nocturnal behavior. We used site occupancy (presence/absence) sampling of pangolin sign (i.e. active burrows) in a protected (Gaurishankar Conservation Area) and non-protected area (Ramechhap district) of central Nepal with multiple environmental covariates to understand factors that may influence occupancy of...
