Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Fragment Edges Benefit a Common Predator of Pollinators via Bottom‐Up Effects

Integrative Zoology, EarlyView.
This study investigated the hypotheses regarding the effects of habitat fragmentation on spider biomass and causing bottom‐up or top‐down effects on multi‐trophic relationships. ABSTRACT Defaunation following habitat fragmentation typically threatens predators at higher trophic levels, which further alter prey and plants via top‐down effects.

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

Agricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

Estimating the Uncertainty in Airborne Birch Pollen Modelling

Background More than 25% of adults in Europe suffer from pollinosis, although variability across countries might be quite large. In Belgium, at least ~10% of people develop allergies due to birch pollen.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

Agricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive
