In this paper we analyze the size and habitat partitioning of the vascular floras of five areas of the NE Iberian Peninsula, representing five distinct vegetation belts and three floristic regions: Mediterranean (basal belt), medio-European (submontane and montane belts) and Boreo-Alpine (subalpine and alpine belts). Each area covered over 1000 ha, and was fairly uniform in terms of potential v...

Knowledge of import, export, and transport of nitrogen (N) in headwater catchments is essential for understanding ecosystem function and water quality in mountain ecosystems, especially as these ecosystems experience increased anthropogenic N deposition. In this study, we link spatially explicit soil and stream data at the landscape scale to investigate import, export and transport of N in a 0....

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...

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...
