The sensitivity and evolutionary trajectory of the mountain cryosphere: Implications for mountain geomorphic systems and hazards

Land Degradation and Development, Journal Year: 2023, Volume and Issue: 34(9), P. 2464 - 2482

Abstract Global climate change gives rise to changing spatial patterns of snow and ice, especially over mountain blocks where orographic synoptic circulation effects play significant roles in creating precipitation glacier development. The presence ice results heat balance changes other land surface feedbacks that have implications for retreat the dynamics geomorphic systems. This study considers sensitivity cryosphere (snow, permafrost) global change, this analysis evaluating stability, generation geohazards. Consideration these issues is informed by evidence from case studies reported literature field observations system worldwide. Results show ‘sensitivity’ forcing has been interpreted defined different ways snow, permafrost systems, with respect properties such as albedo, mass or rapidity change. There are also differences between permafrost, regions therefore likely follow trajectories response forcing, related their physiographic extent cryospheric coverage.

Hybrids as mirrors of the past: genomic footprints reveal spatio-temporal dynamics and extinction risk of alpine extremophytes in the mountains of Central Asia

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: April 17, 2024

Hybridization is one of the key processes shaping lineage diversification, particularly in regions that experienced strong climate oscillations. The alpine biome with its rich history glacial-interglacial cycles and complex patterns species distribution shifts offers an excellent system to investigate impact gene flow on population dynamics speciation, important issues for evolutionary biology biodiversity conservation. In this study, we combined genomic data (DArTseq), chloroplast markers, morphology examine phylogenetic relationships permeability boundaries their outcomes among extremophilic Puccinellia (Poaceae) Pamir Mountains, a part Mountains Central Asia hotspot. We determined occurrence interspecific hybrids between P. himalaica pamirica, which demonstrated almost symmetric ancestry from parental did not show signals introgression. According our integrative revision, natural pamirica should be classified as ×vachanica (pro species). Using approximate Bayesian computation inference, uncovered hybridized independently multiple localities over Holocene.

Impact of climate change on the distribution and predicted habitat suitability of two fruit bats (Rousettus aegyptiacus and Epomophorus labiatus) in Ethiopia: Implications for conservation

Ecology and Evolution, Journal Year: 2023, Volume and Issue: 13(9)

Published: Sept. 1, 2023

Fruit bats serve as crucial bioindicators, seed dispersers, pollinators, and contributors to food security within ecosystems. However, their population distribution were threatened by climate change anthropogenic pressures. Understanding the impacts of these pressures through mapping habitat suitability is for identifying high-priority areas implementing effective conservation management plans. We predicted extent Rousettus aegyptiacus Epomophorus labiatus under scenarios using average predictions from four different algorithms produce an ensemble model. Seasonal precipitation, index, land-use land cover, vegetation, mean temperature driest quarter majorly contributed both species. The current sizes suitable habitats R.
