Alternative foraging strategies enable a mountain ungulate to persist after migration loss

Ecosphere, 2017
The persistence of many migratory ungulate populations worldwide is threatened due to anthropogenic impacts to seasonal ranges and migration routes. While many studies have linked migratory ungulate declines to migration disruption or loss, very few have

What is the most efficient and effective method for long-term monitoring of alpine tundra vegetation?

Arctic Science, 2016
Nondestructive estimations of plant community characteristics are essential to vegetation monitoring programs. However, there is no universally accepted method for this purpose in the Arctic, partly because not all programs share the same logistical ...

Hydrochemical Characteristics of Four Retreating Glacier Forefields Off the Coast of Admiralty Bay (King George Island, Maritime Antarctic): Diverse Sources of Metals and Metalloids

Land Degradation &Development, EarlyView.
ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

Functional traits and habitat use: Investigating community assembly in a montane community (Carabidae: Nebria)

Ecosphere
The processes that influence community assembly, such as competition for resources and environmental filtering, are often scale dependent and vary across ecotones.

Recreation Service Supply–Demand Relationship and Driving Mechanism Analysis in the Three Gorges Reservoir Area, China

Land Degradation &Development, EarlyView.
ABSTRACT Clarifying the relationship between the supply and demand of recreation service not only enhances our comprehension of how cultural ecosystem services impact human well‐being, but also offers a theoretical foundation and scientific basis for developing regional landscape management strategies.

Morpho‐Physiological Traits and Dehydration Tolerance of High‐Altitude Andean Wetland Vegetation in the Chilean Atacama Region

Plant-Environment Interactions
High‐altitude wetlands of the Andes (HAWA) are unique ecosystems influenced by substrate conditions and reliant on consistent water supply from precipitation, runoff, groundwater, and glacial melting.

Alpine soil microbial ecology in a changing world.

FEMS Microbiology Ecology, 2018
Climate change has a disproportionally large impact on alpine soil ecosystems, leading to pronounced changes in soil microbial diversity and function associated with effects on biogeochemical processes at the local and supraregional scales.

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

Nordic Journal of Botany, EarlyView.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...
