Global warNing: challenges, threats and opportunities for ground beetles (Coleoptera: Carabidae) in high altitude habitats [PDF]
arXiv, 2020 Aim of this paper is to provide the first comprehensive synthesis about ground beetle (Coleoptera: Carabidae) distribution in high altitude habitats. Specifically, the attention is focused on the species assemblages living on the most common ice-related mountain landforms (glaciers, debris-covered glaciers, glacier forelands and rock glaciers) and on ...

Beyond Elevation: New Metrics to Quantify the Relief of Mountains and Surfaces of Any Terrestrial Body [PDF]
arXiv, 2022 Elevation has long been the standard for quantifying the relief of mountains and other landforms on Earth and beyond. Nevertheless, elevation has its limitations. By itself, a location's elevation reveals little about its vertical position relative to its surroundings, especially for seabed and extraterrestrial features.

Journal of Quaternary Science, EarlyView.ABSTRACT This paper presents evidence of glacier surging in the British landform record. We use new high‐resolution multibeam‐echosounder bathymetry data to map the submarine geomorphology of a former tidewater glacier that drained the Skye Icefield, NW Scotland, during the Younger Dryas Stadial (Greenland Stadial 1) ca. 12.9–11.7 ka.

Ibis, Volume 165, Issue 1, Page 190-203, January 2023., 2023 Several factors may drive bird nest‐site selection, including predation risk, resource availability, weather conditions and interaction with other individuals. Understanding the drivers affecting where birds nest is important for conservation planning, especially where environmental change may alter the distribution of suitable nest‐sites.

Crater-like landform in Bayuda desert (a processing of satellite images) [PDF]
arXiv, 2010 The paper is proposing a survey of a region in Sudan, the Bayuda desert, using the satellite images as obtained from Google Maps. The images reveal the ring granitic structure of the region enclosed by a bend of river Nile. To enhance the features of the landform, images are processed with a method based on fractional calculus, able to increase the ...

The Journal of Wildlife Management, EarlyView.We examined habitat associations from second‐ and third‐order habitat selection studies conducted on greater sage‐grouse and summarize the types of designs used and the qualitative associations reported. We suggest a combination of study design choices and context‐dependence selection patterns can prohibit the transferability of study findings when the

Land Degradation &Development, EarlyView.ABSTRACT Human impact in the form of reservoir construction and river regulation downstream of reservoirs, is causing irreversible alterations to hillslope and river channel connectivity in river catchments. This disruption in the dynamic equilibrium of the river is attributed to sediment accumulation upstream of the reservoir's dam, limited sediment ...

ISPRS International Journal of Geo-Information, 2017 Land management and planning is crucial for present and future use of land and the sustainability of land resources. Physical, biological and cultural characteristics of land can be used to define Land Management Units (LMUs) that aid in decision making ...
