Talin1 Adhesion Morphology and Colocalization With Tensin3 Are Largely Unaffected by Polyacrylamide Substrate Stiffness

Cytoskeleton, EarlyView.
ABSTRACT Cells sense the stiffness of their extracellular matrix (ECM) and adapt their behavior accordingly. We investigated how ECM stiffness affects the spatial organization of talin1, a key mechanosensitive focal adhesion protein. Using polyacrylamide (PA) hydrogels with tunable stiffnesses (0.2–188 kPa), we analyzed cell morphology, migration ...

Stochastic and deterministic processes influencing mountain mire diatom communities across spatial scales

Ecography, EarlyView.
Understanding how deterministic and stochastic processes influence the shape of microorganism community assembly across different spatial scales is essential for disentangling biodiversity patterns. Mires are nutrient‐poor and heterogeneous wetlands that form isolated habitats supporting highly diverse diatom assemblages, particularly in mountainous ...

Recent changes in area and thickness of Torngat Mountain glaciers (northern Labrador, Canada) [PDF]

The Cryosphere, 2017
The Torngat Mountains National Park, northern Labrador, Canada, contains more than 120 small glaciers: the only remaining glaciers in continental northeast North America.

Internal structure of a Himalayan debris-covered glacier revealed by borehole optical televiewing

Journal of Glaciology, 2023
Characterising the structures within glaciers can give unique insight into ice motion processes. On debris-covered glaciers, traditional structural glaciological mapping is challenging because the lower glacier is hidden by the supraglacial debris layer.

Simulating past and future refugia for temperate trees in northern Italy

Ecography, EarlyView.
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...

THE GLACIER COMPLEXES OF THE MOUNTAIN MASSIFS OF THE NORTH-WEST OF INNER ASIA AND THEIR DYNAMICS

Geography, Environment, Sustainability, 2011
The subject of this paper is the glaciation of the mountain massifs Mongun-Taiga, Tavan-Boghd-Ola, Turgeni-Nuru, and Harhira-Nuru. The glaciation is represented mostly by small forms that sometimes form a single complex of dome-shaped peaks. According to

Rock glaciers in mixed lithologies: a case study from Northern Pirin

Revista de Geomorfologie, 2020
Rock glaciers are lobate or tongue-shaped assemblages of poorly sorted, angular-rock debris and ice, commonly found in high mountain environments, which move as a consequence of the deformation of internal ice (Giardino and Vitek, 1988; Barsch, 1996 ...

Everest's thinning glaciers: implications for tourism and mountaineering [PDF]

Geology Today, 2018
Glacier mass loss in the Everest region of Nepal is accelerating in response to a warming climate, which is a trend observed across the central and eastern Himalaya. Thinning glaciers and the development of supraglacial (surface) ponds and large glacial lakes will increasingly restrict access to glacier surfaces and will affect popular trekking routes ...

Climatic drivers prevail in montane and lowland Odonata latitudinal diversity gradients, but human modification erodes lowland patterns

Ecography, EarlyView.
Latitudinal diversity gradients (LDGs) arise from the interplay of historical, ecological, and evolutionary processes, yet these drivers may differ across landforms. Mountains, with steep elevational and climatic gradients, often sustain distinct diversity dynamics compared with adjacent lowlands, where vertical climatic gradients are weak and human ...

Accelerated Volume Loss in Glacier Ablation Zones of NE Greenland, Little Ice Age to Present

Geophysical Research Letters, 2019
Mountain glaciers at the periphery of the Greenland ice sheet are a crucial freshwater and sediment source to the North Atlantic and strongly impact Arctic terrestrial, fjord, and coastal biogeochemical cycles. In this study we mapped the extent of 1,848
