We have studied reciprocal transplant gardens involving the hybrid zone between basin and mountain big sagebrush ( Artemisia tridentata ) in Salt Creek Canyon, Utah, for 9 years. Previously, we showed that the parental taxa and hybrids had superior reproductive and vegetative performance in their native garden. These earlier data supported the Bounded Hybrid Superiority model. Now, after 9 year...
Nurse plant facilitation is a commonly reported plant-plant interaction and is an important factor influencing community structure in stressful environments. Cushion plants are an example of alpine nurse plants that modify microclimatic conditions within their canopies to create favourable environments for other plants. In this meta-analysis, the facilitative effects of cushion plants was expan...
The Alps still comprise the largest natural and semi-natural environments in Central Europe, but even the remotest alpine regions may face drastic changes due to human-induced climate warming. The glaciers of the Alps respond to the ongoing temperature increase of about 1-2°C since the 19th century with a drastic shrinkage. The high mountain vegetation is generally considered to be particularly...
AIM Interspecific hybridization can promote invasiveness of alien species. In many regions of the world, public and domestic gardens contain a huge pool of non-native plants. Climate change may relax constraints on their naturalization and hence facilitate hybridization with related species in the resident flora. Here, we evaluate this possible increase in hybridization risk by predicting chang...
Postglacial climate changes alter geographical distributions and diversity of species. Such ongoing changes often force species to migrate along the latitude/altitude. Altitudinal gradients represent assemblage of environmental, especially climatic, variable factors that influence the plant distributions. Global warming that triggered upward migrations has therefore impacted the alpine plants o...
