Опубликована: Фев. 27, 2025

In recent years, global warming has become a major driver of biodiversity loss, significantly impacting various vertebrate species, including mammals. Consequently, numerous smaller species face extinction risks due to anthropogenic factors as well inadequate assessments and conservation planning. Thus, this study focuses on two recently described endemic giant flying squirrel under the Petaurista genus—Petaurista mishmiensis mechukaensis—found in Arunachal Pradesh, India. Using an ensemble distribution model (SDM), research delineates suitable habitats for these lesser-known evaluates effects climate change habitat fragmentation areas. This analysis aims inform comprehensive management plan their conservation. The identified patches extending beyond current IUCN-designated ranges Pradesh.

Biodiversity in mountain soils above the treeline

ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also case for soils, but no study to date provided an overall synthesis of current state knowledge. Here we fill this gap with a first global analysis published research on cryptogams, microorganisms, and fauna soils above treeline, structured Based corpus almost 1400 publications expertise 37 soil scientists worldwide, summarise what known about distribution patterns each these organismal groups, specifically along elevation, provide overview available knowledge drivers explaining their changes. In particular, document elevation‐dependent decrease faunal while cryptogams there initial increase followed by towards nival belt. Thus, our data confirm key role that elevation plays shaping biodiversity organisms soils. The response prokaryote turn, was more diverse, whereas fungal appeared be substantially influenced plants.

Changing discourses in the third pole: A systematic review of climate change impact on biodiversity in the Hindu Kush Himalaya

Ecological Indicators, Год журнала: 2023, Номер 155, С. 111046 - 111046

Опубликована: Окт. 9, 2023

Climate change has emerged as one of the major threats to biodiversity and Hindu Kush Himalaya (HKH) is facing challenges due a higher rate elevation dependent warming erratic rainfall. The rich bounty ecosystem services provided by this ‘water tower’ ‘Third Pole’ are under risk. Though there scattered sectoral knowledge available, comprehensive understanding on climate its impact lacking in HKH. To fill gap, systematic literature review using search, appraisal, synthesis, analysis (SALSA) was undertaken look at temporal spatial trends research focusing impacts services. increasing trend evolution from multidisciplinarity approach with focus suggested strong influence regional priority global discourse. There clear pattern biophysical environmental focused early phase 1990s societal concerns highlighting vulnerability, adaptation, mitigation measures later phases. also revealed an multidisciplinary, networking bringing innovative tools linking biodiversity. However, showed greater Tibetan plateau alpine decreasing interest forest ecosystems, very negligible wetlands. Studies assessments but relatively low rate. Better representation investments based vulnerable underrepresented countries collaborative emerging areas such restoration larger scale nature-based solutions could contribute resilience

Spatially Explicit climate change vulnerability assessment of ecological systems along altitudinal gradients in the Indian Himalayan region

Environmental and Sustainability Indicators, Год журнала: 2024, Номер 22, С. 100377 - 100377

Spatial ecological vulnerability assessments are important for devising management plans systems to maintain the flow of ecosystem services, especially in mountains. Himalayan mountains, being a fragile ecosystem, have considerable value, however, information on is lacking. The present evaluation attempts prioritize ecosensitive zones by assessing altitudinal Garhwal Himalaya, India framework using mix bio-physical parameters. Eight parameters, viz., Land Use and Cover (LULC), slope, aspect, landscape fragmentation, temperature, precipitation, soil moisture, Normalized Difference Vegetation Index (NDVI)) were identified considered assess vulnerability. Principal Component Analysis (SPCA) results five Components (PCs), which integrated weighted calculation Ecological Vulnerability (EVI). analysis differential across altitudes with above 2000m altitude showed severe classified as potential (36.25 %), slight (35.25 medium (20.25 high (8.25 %) (0.25 %). vulnerable regions prioritized based their per classes region strict protection (24.70 focal (60.41%) composite development (14.89 study suggetsed priority conservation actions addressing areas sustainable region. provides valuable insights associated measures leading most suitable strategies sustainability systems.

Landscape appearance is controlled by a range of different environmental and human-induced factors, although there still lack knowledge about the significance individual factors. Our goal was to identify factors that were significant for landscape change in European Alps rank them according their importance. Therefore, we mapped with standardized survey methodology six typical socio-ecological regions strongly differing socio-economic natural conditions. The results clearly showed has taken place all over last 150–200 years, affecting biodiversity ecosystem services (ES). In general, areas used agriculture have decreased regions, particularly traditionally forms (−72.7 % −6.9 %). greatest decrease took high elevation, agriculturally unfavourable (-72.6 −41.6 %) weak economic conditions (−62.9 −20.9 forest spread on large scale abandoned land economically strong but also settlements monotone intensively cultures. As consequence changes, plant species diversity declined, favourable good site (−62.7 −7.2 %), while it far less (−20.1 −0.7 Regulation & maintenance cultural ESs decreased, whereas provisioning ES generally increased. regional framework play much more important role development than national frameworks. Higher "green subsidies" reduced intensification trend agriculture, led increased abandonment. addition, remained diverse, declined many This demonstrates interpreting historical dynamics analysing impacts can be valuable guide sustainable decision-making processes.

Habitat Loss in the IUCN Extent: Climate Change-Induced Threat on the Red Goral (Naemorhedus baileyi) in the Temperate Mountains of South Asia

Biology, Год журнала: 2024, Номер 13(9), С. 667 - 667

Опубликована: Авг. 27, 2024

Climate change has severely impacted many species, causing rapid declines or extinctions within their essential ecological niches. This deterioration is expected to worsen, particularly in remote high-altitude regions like the Himalayas, which are home diverse flora and fauna, including mountainous ungulates. Unfortunately, of these species lack adaptive strategies cope with novel climatic conditions. The Red Goral (Naemorhedus baileyi) a cliff-dwelling classified as “Vulnerable” by IUCN due its small population restricted range extent. most all goral residing temperate mountains northeastern India, northern Myanmar, China. Given population, this highly threatened climate habitat disruptions, making mapping modeling crucial for effective conservation. study employs an ensemble approach (BRT, GLM, MARS, MaxEnt) distribution assess distribution, suitability, connectivity addressing critical gaps understanding. findings reveal deeply concerning trends, model identified only 21,363 km2 (13.01%) total extent suitable under current limited alarming, it leaves very little refuge thrive. Furthermore, situation compounded fact that around 22.29% falls protected areas (PAs), further constraining species’ ability survive landscape. future projections paint even degraded scenarios, predicted decline over 34% excessive fragmentation In addition, present identifies precipitation seasonality elevation primary contributing predictors species. nine designated transboundary PAs among them highlight role supporting survival time. Moreover, Dibang Wildlife Sanctuary (DWLS) Hkakaborazi National Park revealed largest scenario. highest mean was found between DWLS Mehao (0.0583), while lowest observed Kamlang Namdapha (0.0172). also suggests strategic management planning vital foundation research conservation initiatives, aiming ensure long-term natural habitat.
