Local adaptation to climate inferred from intraspecific variation in plant functional traits along a latitudinal gradient

Conservation Physiology, Journal Year: 2024, Volume and Issue: 12(1)

Published: Jan. 1, 2024

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

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

Frontiers in Ecology and Evolution, Journal Year: 2021, Volume and Issue: 9

Published: Nov. 18, 2021

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

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.

Leaf trait variation within individuals mediates the relationship between tree species richness and productivity

Oikos, Journal Year: 2023, Volume and Issue: 2024(2)

Published: Dec. 5, 2023

In forest ecosystems, many ecosystem functions such as tree growth are affected by species richness. This biodiversity–productivity relationship (BPR) is mediated leaf traits, which themselves known to be influenced richness; at the same time, primary organs of light capture, they an important factor for growth. However, how a tree's ability phenotypically adjust its traits within‐individual gradient has largely been unexplored. Furthermore, it not impacts within‐tree trait variation on individual sums up productivity community scale. this study we tested richness, mean and extinction coefficient within crown influence We measured these variables in temperate plantation Kreinitz biodiversity experiment. found that between richness via trees, turn was modified availability. particular, trees monocultures show higher variation, partly compensates lack among‐species thus affects BPR. It seems operates both through increased acquisitive values two processes cancelled out each other resulted absence significant effect our study. conclusion, understand BPR, underlying know ones reinforce or oppose other. highlights importance including ecological research one moderator
