Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Die eiszeitliche Vergletscherung des Bayerischen Waldes [PDF]

open access: yesEiszeitalter und Gegenwart, 1967
Corries, abrupt slopes, steep heads closing basin-like valleys, waterfalls and rapids are the characteristic association of land forms in the highest parts of the Bayrischer Wald (Bavaria) above about 1000 m.

The art of avoidance: bedsite use, antipredator strategies, and predation risk in white‐tailed deer fawns

open access: yesThe Journal of Wildlife Management, EarlyView.
Horizontal visibility, rather than concealment cover, drove fawn bedsite use and predation risk. Greater field of view decreased the odds of coyote predation, likely by facilitated by early detection. As fawns transitioned from hiders to followers, they shifted from using dense overstory concealment to more open overstory that favored improved escape ...

Across the Arid Diagonal: deglaciation of the western Andean Cordillera in southwest Bolivia and northern Chile

open access: yesCuadernos de Investigación Geográfica, 2017
Here we review published cosmogenic records of glaciation and deglaciation from the western cordillera of the arid subtropical Andes of northern Chile and southwest Bolivia.

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Distance sampling: comparing walked transects and road transects for rock ptarmigan densities and population trends

open access: yesWildlife Biology, EarlyView.
We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.

Build-up and chronology of blue ice moraines in Queen Maud Land, Antarctica

open access: yesQuaternary Science Advances, 2020
Blue ice moraines are common supraglacial landforms in Antarctica and they are considered to record the ice volume fluctuations. In this study, we use photogrammetry and the analysis of multiple cosmogenic nuclides (10Be, 26Al, and in-situ 14C) in ...

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

Late Holocene history of the Shkhelda Glacier, Northern Caucasus, according to remote sensing, dendrochronology and cosmogenic (10Be) dating of moraines

open access: yesЛëд и снег
The position of the Shkhelda valley glacier front (Elbrus region, 43.18N, 42.64 E) for the period from the 1880s to 2022 was reconstructed based on interpretation of aerial and satellite images and old maps.
