Spatial interactions between trees influence forest community succession. The objective of this study was to investigate how shifts in composition and proximity tree species affect stand development over time mixed systems. At six locations across the Fishlake National Forest, Utah, USA, stands where facilitation has been documented previously, tree-ring samples were collected from aspen subalp...

Interest in arid ecosystems as a source of food supply for rapidly increasing population of the world, on the one hand, and the problems pertaining to the climatic characteristics, water shortages and soil sensitivity for the inhabitants in such areas, on the other have prompted efforts at both national and international levels to develop a better understanding of these problems as well as to f...

Abstract Despite the emerging body of literature on entrepreneurial ecosystems (EEs), theoretical development is still in its infancy. In this article, we explicitly draw upon analogy forest (FEs) with an EE to extrapolate regional ecosystem (REE) as alternate conceptual framework. The REE considers a region’s socioeconomic activity and stability performance whole, influenced by partitioned int...

Rocky Mountain forests are currently experiencing a bark beetle epidemic of unprecedented severity and extent. Forest regeneration following bark beetle outbreaks is driven by the survival and density of understory trees (advance regeneration). The composition and density of the advance regeneration may differ substantially from the pre-outbreak overstory and across environmental gradients. We ...

0 Subalpine meadow communities are in~uenced by edaphic and microclimatic gradi! ents\ and should be a}ected by climate change that a}ects these local controls[ We used pollen preserved in meadow soils to investigate the long!term interaction of these factors in a 0!ha subalpine meadow in the Olympic Mountains\ Washington\ USA[ 1 To describe the spatial scale at which soil pollen is related to ...

Subalpine fir mortality and stand decline are increasingly evident in British Columbia (B.C.). This long-term study confirmed Dryocoetes confusus to be the major disturbance agent high-elevation subalpine forests, killing over two-thirds of eleven one-hectare plots. D. infestations mature stands can described as early-, mid-, or late-phase. The transition from early- through late-phase is chara...

The relative number of seeds produced by competing species can influence the community structure; yet, traits that influence seed production, such as pollinator attraction and floral colour, have received little attention in community ecology. Here, we analyse floral colour using reflectance spectra that include near-UV and examined the phylogenetic signal of floral colour. We found that coflow...
