Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

open access: yesOikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...

A plant–pollinator invasional meltdown: the Japanese pagoda tree Styphnolobium japonicum facilitates the invasion of the giant resin bee Megachile sculpturalis

open access: yesOikos, EarlyView.
An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

The potter wasp genus Allorhynchium from Vietnam, with descriptions of three new species and a new country record (Hymenoptera, Vespidae, Eumeninae)

open access: yesZooKeys, 2023
Species of the potter wasp genus Allorhynchium van der Vecht (Eumeninae: Odynerini) occurring in Vietnam are presented. Seven species have been recorded from Vietnam. Of them, three species are described as new to science: Allorhynchium latum Nguyen, Tran & MT Nguyen, sp. nov., A. moerum Nguyen & AD Nguyen, sp. nov., and A. setosum Nguyen &

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Taxonomy of the Indo-Malayan presocial potter wasp genus Calligaster de Saussure (Hymenoptera, Vespidae, Eumeninae) [PDF]

open access: yesJournal of Hymenoptera Research, 2016
The taxonomic history and current taxonomic status of the presocial potter wasp genus Calligaster de Saussure, 1852, at generic and species levels are reviewed. The hitherto-unknown female of Calligaster viridipennis Giordani Soika, 1960, is described based on specimens newly collected in Central and Southeast Sulawesi.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

open access: yesIntegrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

The Form of Agency

open access: yesNoûs, EarlyView.
ABSTRACT Philosophers often think agency is essentially connected with rationality, intention, or control. However, Minimalists argue that agency is just the power to cause a change; acids and boulders are agents too. Many philosophers treat Minimalism as a wild outlier, assuming its falsity without argument.

Direct Ink Writing of Geopolymer Composites Reinforced With Polypropylene Fibers

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT Polypropylene fiber (PPf) reinforced geopolymer inks were systematically optimized for extrusion‐based additive manufacturing through regulation of ink composition, rheological parameters, nozzle size, and fiber content. The effects of polyethylene glycol (PEG) content and H2O to K2O ratio on printability were investigated.

Establishing Baseline Information for the Risk of Flatheaded Borer Attack in Specialty Tree Crops Using Trapping and On‐Farm Surveys

open access: yesJournal of Applied Entomology, Volume 150, Issue 8, Page 1088-1101, September 2026.
ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.
