Range‐wide intraspecific variation reflects past adaptation to climate in a gypsophile Mediterranean shrub

Journal of Ecology, Volume 112, Issue 7, Page 1533-1549, July 2024.
Despite strong specialization to gypsum soils, past divergent selection related to climatic gradients has driven adaptive population differentiation in Lepidium subulatum. All populations showed high but similar plasticity to drought, indicating that selection did not act against plasticity in harsh environmental conditions.

Leaf traits and leaf‐to‐air temperature differences in tropical plants suggest variability in thermoregulatory capacities across elevations

Biotropica, Volume 56, Issue 4, July 2024.
Plant thermoregulation is essential for understanding the potential effects of climate change on terrestrial ecosystems. This study provides evidence indicating variation of leaf functional traits and leaf‐to‐air temperature across the elevation gradient.

Tree and mycorrhizal fungal diversity drive intraspecific and intraindividual trait variation in temperate forests: Evidence from a tree diversity experiment

Functional Ecology, Volume 38, Issue 5, Page 1089-1103, May 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The study of tree species coexistence is crucial to understand the assembly of forest communities. In this context, trees adjust their traits in response to the interactions with other trees and, specifically, as a result of the competition for resources.

Insect herbivory but not plant pathogen infection drive floral volatile‐mediated indirect effects on pollinators and plant fitness in Brassica rapa

Journal of Ecology, Volume 112, Issue 2, Page 402-415, February 2024.
Plants subjected to herbivory by the aphid Brevicoryne brassicae exhibited a marked reduction in the emission of two volatile organic compounds (nonanal and 2‐butyl‐1‐octanol), experienced lower pollinator visits and produced seeds of lower quality in terms of seed biomass and germination rate.
