The study of positive species interactions is a rapidly evolving field in ecology. Despite
decades of research, controversy has emerged as to whether positive and negative …

Once seen as anomalous, facilitative interactions among plants and their importance for
community structure and functioning are now widely recognized. The growing body of …

A significant part of this book is based on a graduate course on pattern formation which I
have been teaching during the past two decades in the Physics Department at Ben-Gurion …

Since proposed two decades ago, the stress‐gradient hypothesis (SGH), suggesting that
species interactions shift from competition to facilitation with stress, has been widely …

Environmental gradients may influence a plant's physiological status and morphology, which
in turn may affect plant–plant interactions. However, little is known about the relationship …

In many regions of the world, such as Southern Europe and most Mediterranean areas, the
frequency and magnitude of droughts and heat waves are expected to increase under …

Previous syntheses on the effects of environmental conditions on the outcome of plant–plant
interactions summarize results from pairwise studies. However, the upscaling to the …

Facilitation (positive interactions among organisms) in communities has been the subject of
increasing interest for community ecologists since the mid-nineties (Fig. 1), although this is a …

According to broad‐scale application of biogeographical theory, widespread retractions of
species' rear edges should be seen in response to ongoing climate change. This prediction …

According to the stress gradient hypothesis (SGH), ecological interactions between
organisms shift positively as environmental stress increases. In the case of associational …
