Interspecific differences in microhabitat use expose insects to contrasting thermal mortality

open access: yesEcological Monographs, Volume 93, Issue 2, May 2023., 2023
Abstract Ecotones linking open and forested habitats contain multiple microhabitats with varying vegetal structures and microclimatic regimes. Ecotones host many insect species whose development is intimately linked to the microclimatic conditions where they grow (e.g., the leaves of their host plants and the surrounding air).

Communities of endophytic fungi in a Puerto Rican rainforest vary along a gradient of disturbance due to Hurricane Maria

open access: yesEcology and Evolution, Volume 12, Issue 12, December 2022., 2022
Even more than a year after the catastrophic passage of Hurricane Maria, communities of endophytic symbionts in a Puerto Rican rainforest bear a signature of forest disturbance. Abstract Increases in the frequency and intensity of hurricanes influence the structure, function, and resilience of Caribbean forests.

Flexible drought deciduousness in a neotropical understory herb

open access: yesAmerican Journal of Botany, Volume 109, Issue 8, Page 1262-1272, August 2022., 2022
Progression of leaf loss and growth between wet seasons. Abstract Premise Adaptive divergence across environmental gradients is a key driver of speciation. Precipitation seasonality gradients are common in the tropics, yet drought adaptation is nearly unexplored in neotropical understory herbs. Here, we examined two recently diverged neotropical spiral

The role of nutritional impairment in carbon‐water balance of silver fir drought‐induced dieback

open access: yesGlobal Change Biology, Volume 28, Issue 14, Page 4439-4458, July 2022., 2022
Declining silver fir trees show lower foliar concentrations of essential nutrients such as P, K, Cu and Ni than non‐declining trees. This nutritional impairment exacerbates and amplifies the negative effects of drought on tree functioning and growth, considering the relationship of tree nutritional status with water‐use efficiency and growth resilience

Polyploidy promotes divergent evolution across the leaf economics spectrum and plant edaphic niche in the Dianthus broteri complex

open access: yesJournal of Ecology, Volume 110, Issue 3, Page 605-618, March 2022., 2022
Our results indicated shifts in ecological strategies across Dianthus broteri cytotypes and suggested a powerful role of polyploidy in overcoming constraints for the evolution of plant functional traits. Abstract The evolution of the leaf economics spectrum (LES) is known to be constrained by genetic relatedness but also promoted at small geographical ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

open access: yesNew Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Integrated demographic strategies are more strongly associated with variation in conspecific density dependence than single traits in tropical tree seedlings

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Species‐specific conspecific negative density dependence (CNDD) varied widely among tropical tree species. CNDD was strongest in fast‐growing species and tall, long‐lived pioneers, weakly related to most functional traits except wood density and strongest in rare species. These results show that integrated life‐history strategies explain CNDD variation

Global insular leaf size shifts follow the island rule, independently of insect herbivory and macroclimate

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
We found a positive, non‐linear, saturating relationship between mainland and island leaf sizes, reflecting an island rule‐like pattern. Small‐leaved mainland species tend to develop larger leaves on islands, while this effect weakens for larger‐leaved species, a pattern consistent across both conspecific and congeneric comparisons. Abstract The island

Species functional traits affect regional and local dominance across western Amazonian forests

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A
