Differential effects of agricultural expansion on wild bee taxonomic and functional diversity

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

Trait‐based species selection for restoration: A case study from tropical landscapes dominated by bracken

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results can be used by stakeholders to select the species best suited for active restoration projects in bracken‐dominated areas throughout the tropical region. Furthermore, our trait‐based approach, which considers seedling performance in disturbed areas, can serve as a guide for species selection in restoration programmes in other disturbed ...

Unveiling Short‐Scale Responses: How Pico‐ and Nanoeukaryotic Plankton Navigate Environmental Variability in a Coastal Upwelling System

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 2, April 2025.
We investigated the taxonomic composition and dynamics of pico‐ and nanoeukaryotes in an upwelling bay, providing insights into potential future trends. Advection and trophic interactions emerged as key factors shaping these communities. During downwelling, taxonomically unclassified picoeukaryotes and minor nanoeukaryotic taxa was dragged into the ria.

Eigenfilter: método de diseño de filtros FIR con restricciones temporales.

open access: yesTelemática, 2015
Con el objetivo de minimizar los errores en la demodulación de señales digitales como PSK o FSK, se hace necesario emplear filtros cuya respuesta al paso unitario tenga un tiempo de subida lo más pequeño posible.
