Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

The Anatomical Record, Volume 309, Issue 5, Page 1299-1312, May 2026.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Analysis of Dendritic Specializations in Two Classes of Kenyon Cells in the Mushroom Body of the Adult Honeybee, Apis mellifera

Journal of Comparative Neurology, Volume 534, Issue 5, May 2026.
Honeybee mushroom bodies (MBs), sites for learning and memory, house two classes of intrinsic neurons: class I and II Kenyon cells (KCs) that form synaptic complexes with boutons of projection neurons (PNs) from primary sensory neuropils. Dendrites of both KC classes were restricted to distinct unimodal MB compartments.

Transcriptomic and DNA Methylation Profiles of Alternative Aphid Morphs and Genotypes

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Graph showing the correlation between differentially expressed genes and differentially methylated genes. There is no correlation between gene expression and DNA methylation level in pea aphid polyphenism. ABSTRACT Pea aphids can develop alternative morphs when exposed to stressful conditions, showing differences between genotypes in their stress ...

Conventional Wisdom Revised in Terms of a Diversity‐Uncertainty Model for the Effect of Host Genetic Diversity on Mean Epidemic Size and Its Variability

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We develop an Epidemic Diversity Model to explore how host–parasite genetic diversity influences both the mean and variability of parasite success. By re‐analysing effect size data from 211 comparisons across 48 studies, we show that host genetic diversity reduces mean parasite success only for specialist parasites, while its effect on variability ...

Network rewiring and species turnover stabilize plant–pollinator interactions across habitats and seasons in dry forest

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Mutualistic interactions between plants and pollinators are fundamental to biodiversity maintenance and ecosystem resilience, yet their dynamics across space and time in tropical dry forests have not been widely examined. We analyzed plant–pollinator networks across seasons and habitat types in the highly seasonal and fragmented dry forest of ...

Care for bees: for many reasons and in many ways [PDF]

Pollinating insects are in decline, probably worldwide. This may imply a pollination crisis, for (food) crops as well as wild plants. Eventually this decline might result in great economic losses, a human food crisis and loss of natural biodiversity ...

Indirect effects of herbicide use on the Bombus community mediated through changes to shrub and forb communities

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Pesticides are used around the world to control and suppress undesirable species. In many cases the direct effects of pesticides are well understood and characterized, describing how environments are likely to be altered. However, these direct effects are likely to cause other species to respond to ecosystem alteration. For example, herbicides

Tailoring Thermophysical Properties and Multiscale Machine Learning Modeling of 2D Nanomaterial‐Infused Beeswax as a Green NePCM for Sustainable Thermal Management Systems

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
This study develops eco‐friendly two‐dimensional nanoparticle‐enhanced phase change materials (2D NePCMs) using biodegradable beeswax infused with rGO, GO, and MXene nanoparticles. Experimental results demonstrated up to 21.9% enhancement in thermal conductivity with minimal latent heat loss, while machine learning models achieved >95% predictive ...

The Assessment of the Effect of Nano Propolis Against Melanoma Cell Line, and Its Radio Sensitization Effect

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Iranian nano propolis stoppeded the cell cycle at G1 phase, increased the apoptosis and anti‐metastasis effect rather than propolis extract. The combination of Iranian nano propolis with ionizing radiataion significantly increased its anticancer properties on cancer cells and protected normal cells. The better and more effective performance of propolis

Exploring perceptions of Italian urban wildlife on TikTok

People and Nature, Volume 8, Issue 5, Page 1470-1484, May 2026.
Abstract In Western cities, some animals are valued for their beauty, rarity or usefulness, while others are dismissed as unwelcome. This distinction reflects the cultural meanings attached to each species and frequently conflicts with ecological priorities.
