Comunidades de sírfidos (Diptera) asociadas a coberturas influenciadas por actividades antrópicas en los cerros orientales de Bogotá, Colombia

open access: yesCaldasia, 2020
La diversidad taxonómica y funcional de los sírfidos los hace fundamentales en los ecosistemas. Además, su sensibilidad a la fragmentación del hábitat por factores antrópicos los hace buenos indicadores ecológicos de la conservación ecosistémica ...

Unravelling the spatial and temporal variability of natural disturbances in European forests

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
The heterogeneity of natural disturbance patterns and high temporal variability across European Forest suggest the need of adopting context‐dependent management strategies tailored to both the dominant disturbance agent and local environmental conditions, particularly in the most vulnerable regions, such as the Iberian Peninsula—with large and frequent

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Streaming potential analysis of hair variation: Ethnicities and environmental exposures

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 2, Page 230-242, April 2026.
Ethnicity and weathering shape electrokinetic behaviour and particle deposition in hair. ζ‐potential magnitudes ranked Caucasian > Indian > Chinese with no significant root‐tip variations. Deposition patterns generally correlate with ζ‐potential but differ by ethnicity, implicating other factors.

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.
