Marine macroalgae ('seaweeds') are critical to coastal ecosystem structure and function, but also vulnerable the many environmental changes associated with anthropogenic climate change (ACC). The local habitat conditions underpinning observed predicted ACC-driven in intertidal macroalgal communities complex probably site-specific operate addition more commonly reported regional factors such as sea surface temperatures.

Effects of Soil Properties, Temperature and Disturbance on Diversity and Functional Composition of Plant Communities Along a Steep Elevational Gradient on Tenerife

Elevational variation of vegetation has been interest for centuries, and a prominent example such pronounced changes can be found along the steep elevational gradient on Tenerife, Canary Islands, 200 km off West-African cost. The 3,718-m ascent to peak island volcano, Teide, offers unique opportunity investigate associated in vegetation. However, elevation is not directly acting factor, but represents several natural environmental gradients. While temperature globally rather uniform effects plant communities are well understood, much less known about region-specific change chemical soil properties their impact Because human interference takes place even at high-elevation areas, we considered human-induced disturbance as important third factor upon community assemblages. In our study, compared properties, species richness, functional identity diversity Tenerife. We used pairs study plots: adjacent road close by. each plot, did relevées, took samples, installed loggers. Additionally, collected leaf samples measure traits 80% recorded species. With increasing elevation, cation concentrations, exchange capacity (CEC) pH decreased significantly, while carbon phosphorus ratio slightly peaked mid-elevations. Temperature had strongest effects, richness favoring with fast resource acquisition. Species was higher verges, indicating positive effect reduced competition artificially generated heterogeneity. detect characteristics. Vice versa, find increased concentrations cations favored acquisitive communities. Surprisingly, could reveal any influence diversity. importance aligns findings from large-scale biogeographic studies. results also emphasize that it necessary consider local abiotic drivers, like disturbance, understand

Ascertaining the traits important for acclimation and adaptation is a critical first step to predicting fate of populations species facing rapid environmental change. One primary challenges in trait-based ecology understanding patterns processes underpinning functional trait variation plants. Studying intraspecific across latitudinal gradients offers an excellent

Size‐dependent and environment‐mediated shifts in leaf traits of a deciduous tree species in a subtropical forest

Abstract Aims Understanding the joint effects of plant development and environment on shifts intraspecific leaf traits will advance understandings causes trait variation. We address this question by focusing a widespread species Clausena dunniana in subtropical broad‐leaved forest. Methods sampled 262 individuals C . at two major topographic habitat types, slope hilltop, within karst forests Maolan Nature Reserve southwestern China. measured individual level (i.e., specific area (SLA), area, dry‐matter content (LDMC), thickness) that are associated with resource‐use strategies. adopted linear mixed‐effects model which size first principal component basal diameter height) environmental factors habitat, canopy height, rock‐bareness) were used as independent variables, to estimate their influences traits. Key Results found (1) independently drove , explained less variances than factors. (2) With increasing size, had increasingly smaller SLA but larger sized leaves. (3) The most influential factor was habitat; it all four examined. hilltops representing more conservative strategies (e.g., SLA, higher LDMC) slopes. On top that, local‐scale further modified shifts. Conclusions Plant shaped variations forest Maolan. Compared played critical role shaping variations, potentially also underlying individual‐level
