Bee community and trait‐based responses to fire in a Mediterranean landscape

Insect Conservation and Diversity, EarlyView.
Fire drives a short‐term increase in bee abundance and diversity, despite its strong negative impact on floral resources. Acting as an environmental filter, fire shapes bee communities as increased post‐fire fine‐scale heterogeneity favors bees with specific functional traits such as ground‐nesting and generalist species.

Estimating wild bee population size with validated distance sampling

Insect Conservation and Diversity, EarlyView.
Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...

Priority areas for arthropod conservation in the Iberian Peninsula and Balearic Islands: Insights from a multi‐taxon distributional database

Insect Conservation and Diversity, EarlyView.
Using over 416,000 occurrence records from 13 arthropod groups (6233 arthropod species), we mapped large‐scale richness patterns and identified biodiversity hotspots across the Iberian Peninsula and Balearic Islands. Hotspot congruence among arthropod groups was low, underscoring the importance of integrative, multi‐taxon approaches for conservation ...

Soil acidity stress: A faba bean (Vicia faba L.) cultivation challenge in Ethiopia, mitigation, and future perspectives

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
ABSTRACT Soil acidity is among the most important abiotic stresses globally constraining agricultural land and crop productivity. Globally, about 30%–40% of total arable land is under the influence of acidic soil. In Ethiopia, approximately 43% of arable land and productive areas are constrained by acidic soil.
