Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

open access: yesIntegrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)

open access: yesArchaeometry, EarlyView.
ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...

Cold‐Induced Lipidomic Remodelling Is Associated With Brown Adipose Tissue Mean Radiodensity in Humans

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Cold exposure activates brown adipose tissue (BAT) and promotes thermogenic and metabolic adaptations. While BAT activation has been linked to improved cardiometabolic health, how acute cold exposure reshapes the circulating lipidome in humans remains incompletely understood.

Drought Stress Promotes Aphis gossypii Growth but Decreases Host Attractiveness in Melon

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Drought stress is a significant environmental factor that affects plant physiology and growth, leading to considerable detrimental effects on crop productivity. Cucumis melo, which is widely cultivated for its economic value, is particularly susceptible to water scarcity.
