Abstract Background Chemical pollution forms a severe threat for human and environmental health. While the risks European lowland water bodies are well known, there is little knowledge on remote aquatic ecosystems particularly mountain lakes, despite their importance provision of freshwater. Here, we critically review current exposure risk by chemical lakes present tiered approach how to advance effectively our understanding in future. Results Generally, pollutant monitoring data currently incomplete, with many regions substances having been only poorly investigated. More reliable exist persistent organic pollutants (POPs). However, increasing evidence that even exposed wide range pollutants. Among them potent pesticides used agricultural biocidal applications, such as diazinon permethrin. The follows complex pattern. Pollutants introduced into via atmospheric deposition run-off from watershed, but also local sources, like tourism pastoralism. Our assessment recent biomonitoring studies suggest widespread chronic toxic crustacean ranges. If ranges pastoralism, acute effects possible. Thereby, vulnerability has be expected high due harsh conditions at altitudes, organism’s traits, insular position lower species richness altitudes. Furthermore, biological processes leading degradation under ecological ecosystems. Conclusion sensitivity investigated, existing it very likely do suffer pollution-induced toxicity. To verify this suggestion expand knowledge, necessary future combine more holistic modelling links effects. Only then will possible obtain impact protect these fragile

Preserving Short‐Sward Natural Grasslands May Provide Suitable Foraging Habitat for a Climate‐Threatened Alpine Species Along Ski‐Pistes

ABSTRACT In many mountain regions, tourism represents one of the main sources income. Winter sports are often prevalent and, in last decades, infrastructures linked to ski industry have expanded worldwide ranges. Mountains dramatically suffering effects climate change, species contracting or declining and ski‐pistes predicted shrink towards higher elevations. For high‐elevation ecosystems species, construction is a major issue, impacting on such as alpine birds already threatened by change. Here, assessing ultimate drivers habitat selection during breeding season, we investigated impacts Dolomites foraging behaviour white‐winged snowfinch Montifringilla nivalis , an iconic bird highly Our results show that snowfinches, critical period nestling rearing, prefer forage snow patches short grass medium slope, characteristics frequently found studied ski‐pistes. We also observed marked effect temperature‐solar radiation interaction: snowfinches sunlit areas when ambient temperature low, while under temperatures they shady zones, probably due specific physiological/thermoregulatory requirements. Foraging associated with some shared environmental characteristics. This implies impact could be mitigated adequate management targeted at maintaining short‐sward grassland (e.g., through avoidance/reduction machine grading controlled grazing) residual (preventing complete levelling slope shallow depressions lower solar radiation). Such strategies contribute reducing ecological footprint current future resorts ecosystems.

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

Ecological Indicators, Journal Year: 2023, Volume and Issue: 155, P. 111046 - 111046

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.

Recreational activities often result in a spatial and/or temporal activity shift wildlife. With the concurrent development of outdoor and increase temperatures due to climate change, mountain species face increasing pressures terms managing their pattern limit both risk exposure thermal discomfort. Using more than 15 years long-term GPS sensor data, we investigated how female northern chamois, Rupicapra rupicapra rupicapra, adjust summer circadian spatiotemporal variation hikers' presence. Chamois' behaviour was affected by high During hottest days, they shifted peak earlier morning, were active at night during peaks, less daytime had longer morning evening peaks compared coldest days. Yet, total daily only slightly different days Conversely, disturbance weak effects on levels timing peaks. This is especially true for (weekdays versus weekends public holidays), possibly because most weekdays fell school holidays. Only conditions, shorter females living exposed areas least areas. One possible explanation overall low effect may be that behavioural changes buffering animals from presence (e.g. moving away trails) allow them just marginally modify pattern. In context ongoing socioenvironmental changes, it critical conserve habitats providing refuges against heat protection mitigate potential detrimental consequences.

Earth, Journal Year: 2025, Volume and Issue: 6(1), P. 2 - 2

Published: Jan. 9, 2025

To understand the impact of climate change on water resources, this research investigates long-term rainfall trends and anomalies across Northeastern India (NEI), covering Assam Meghalaya (A&M); Nagaland, Manipur, Mizoram, Tripura (NMMT); Sub-Himalayan West Bengal Sikkim (SHWB&S) using different statistical tests including innovative trend analysis (ITA). The study scrutinizes 146 years statistics, analyses, variability, probability distribution changes to comprehend its implications. Furthermore, in assured probabilities was also worked out rainfed agriculture India. Comparative between all (AI) NEI reveals that receives nearly double annual compared AI (2051 mm 1086 mm, respectively). Despite resembling broad patterns, displays intra-regional variations, underscoring necessity for region-specific adaptation strategies. Statistical characteristics like coefficient skewness (CS) kurtosis indicate skewed distributions, notably during winter seasons NMMT (CS~1.6) SHWB&S (CS~1.5). Trend analyses reveal declining trends, especially conspicuous NEI’s (−1.88) monsoon (−2.9) seasons, where rate decrease higher last three decades. return periods at 50% 75% levels increased sharply by over 30% recent half, posing challenges upland hill farming. highlights increasing variability negative NEI, exacerbating decreasing significantly impacting agricultural productivity. These findings underscore urgency adaptive measures tailored evolving ensuring sustainable practices efficient resource management.
