The Missing Branches of the Bee Tree of Life: Addressing Global Darwinian Shortfalls and Their Drivers

open access: yesJournal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim Estimate the Darwinian shortfall (i.e., the lack of knowledge about phylogenetic relationships) of bees worldwide, as well as identify their drivers. Location Global. Taxon Bees (Hymenoptera, Anthophila). Methods We built phylogenies for over 12,000 bee species, combining the most comprehensive phylogeny and an algorithm with random ...

Evaluation of Bee Diversity within Different Sweet Cherry Orchards in the Sultandaği Reservoir (Turkey)

open access: yesJournal of Apicultural Science, 2015
Many varieties of sweet cherry are self-incompatible. Therefore, sweet cherry orchards require a huge population of pollinator bees to carry out an adequate amount of pollen transfer between the different varieties.

Sampling of flower-visiting insects: Poor correspondence between the catches of colour pan-trap and sweep netting

open access: yesEuropean Journal of Entomology, 2019
Pollinating insects are important and therefore, it is important to be able to assess and monitor changes in their abundance. Consequently, it is essential that the methods used to collect data have some level of precision and are accurate.

Estimating the body size of orchid bees (Hymenoptera: Apidae: Euglossini) using the distance between their tegulae

open access: yesEuropean Journal of Entomology
Body mass is an important morphological trait, which is associated with the physiology and ecology of insects. In the past, estimates of body mass were often based on general mathematical equations in which body mass was related to linear measurements of

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

open access: yesInsect Conservation and Diversity, Volume 19, Issue 4, Page 757-768, July 2026.
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 ...

Moderately thinning encroaching shrub species is key to balancing rangeland restoration and arthropod biodiversity conservation in Namibia

open access: yesJournal of Applied Ecology, Volume 63, Issue 6, June 2026.
Moderate manual thinning (50F) maintained arthropod diversity comparable to untreated controls while reducing shrub dominance, demonstrating that structural heterogeneity buffers biodiversity loss during rangeland restoration in Namibian bush‐encroached systems. These findings advocate mosaic debushing strategies that preserve vegetation complexity and
