Inverse sky islands: lowland river valleys drive microbial divergence while high elevations select for convergence in massive mountain ecosystems

Ecography, EarlyView.
Mountain ecosystems are often interpreted through the lens of the ‘sky island' model, where high‐elevation habitats function as isolated archipelagos. However, this model's applicability to massive, topographically complex mountain ranges where highlands are continuous and lowlands are fragmented remains untested.

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

Using machine learning to uncover synergies between forest restoration and livelihood support in the Himalayas

Ecology and Society
In recent years, governments and international organizations have initiated numerous large-scale tree planting projects with the dual goals of restoring landscapes and supporting rural livelihoods.

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

Grassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.

Ethnobotany of the Himalayas: The Nepal, Bhutanese, and Tibetan Himalayas

, 2020
Plant use in the Nepal Himalaya, recorded in the 6500-year-old text of the Rigveda, ranks among the earliest uses of medicinal plants (Malla and Shakya 1984). Another early account, the Saushrut Nighantu, is perhaps the oldest Nepali medicinal plant book,

Threats to endangered musk deer (Moschus chrysogaster) in the Khaptad National Park, Nepal

Folia Oecologica, 2019
The Alpine musk deer (Moschus chrysogaster) is classified as an “Endangered” species by the IUCN Red list category. We studied anthropogenic pressure on the musk deer population in the Khaptad National Park, Nepal.

A simple index for assessing cumulative human impacts on mountain lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Impact of model resolution on simulating the water vapor transport through the central Himalayas: implication for models’ wet bias over the Tibetan Plateau

Climate Dynamics, 2018
Current climate models commonly overestimate precipitation over the Tibetan Plateau (TP), which limits our understanding of past and future water balance in the region. Identifying sources of such models’ wet bias is therefore crucial.

Functional traits shape tree species distribution in the Himalayas

Journal of Ecology, 2020
Plant functional traits determine plant performance and have therefore the potential to shape and predict species distributions along environmental gradients.

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

Nordic Journal of Botany, EarlyView.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...
