Alpine environments are among the habitats most strongly affected by climate change, and
consequently their unique plants and pollinators are faced with the challenge of adapting or …

Diptera are important flower visitors and pollinators for many plant species and in a variety of
habitats. Although Diptera are not as well studied as other groups of pollinators, there is a …

Abstract The genus Empetrum (Ericaceae) is controversially classified taxonomically. It is
conservatively treated as comprising one variable widespread circumboreal/circumarctic …

Abundance and visitation of pollinator assemblages tend to decrease with altitude, leading
to an increase in pollen limitation. Thus increased competition for pollinators may generate …

Widespread plants may provide natural models for how population processes change with
temperature and other environmental variables and how they may respond to global …

PREMISE OF THE STUDY: Seed output of high‐mountain plants in the uppermost life zones
is highly variable. One possible reason might be pollen limitation due to inadequate …

Plant sexual systems can be affected by various environmental factors, and thus show a
range of morphological differences. The associations between plant sexual systems and …

Low pollinator visitation in harsh environments may lead to pollen limitation which can
threaten population persistence. Consequently, avoidance of pollen limitation is expected in …

Rapid climate change in the Arctic may increase sexual reproduction in plants because of
changes in both abiotic factors, such as temperature, and biotic factors, such as pollination …

Abstract Background and Aims The coexistence of hermaphrodites and female-sterile
individuals, or androdioecy, has been documented in only a handful of plants and animals …
