Reindeer grazing controls willows but has only minor effects on plant communities in Fennoscandian oroarctic mires

Arctic, Antarctic, and Alpine Research, 2019
Shrubification of arctic tundra is a well-recognized phenomenon, and it can be particularly rapid in moist habitats. Reindeer grazing can inhibit shrubification, but grazing impacts on mire vegetation have been overlooked.

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

The 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 ...

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

Nordic Journal of Botany, EarlyView.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

Oikos, EarlyView.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

A study of fossil plant remains at the archaeological site in Lomilla (Aguilar de Campoo, Palencia, Spain)

Anales del Jardín Botánico de Madrid, 2001
The discovery of a site with abundant fossil plant remains in the surroundings of Aguilar de Campoo (Palencia, Spain), dated in the early Holocene, allowed us to obtain new data on the composition of foreste in that área. Two species of Pinus and several

Between birch and berries: seasonal dietary niche partitioning among sympatric alpine herbivorous birds

Oikos, EarlyView.
Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...

The investigation of morphological characteristics of willow species in different environmental conditions [PDF]

Zbornik Matice Srpske za Prirodne Nauke, 2016
Alternative or renewable energy is a modern strategy with a good per­spective in the nearest future. There are several directions of renewable energy development that depend on climatic, economic and technological opportunities of a region.

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope
