The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

Influence of forest cover and sex on wing size and shape of a spider‐hunting wasp in the Brazilian Atlantic forest

open access: yesEcological Entomology, Volume 51, Issue 1, Page 165-176, February 2026.
Forest cover significantly influences the wing shape of female Trypoxylon lactitarse. Females exhibit longer and narrower wings, linked to greater flight efficiency and dispersal. Sexual dimorphism indicates that females respond differently to ecological pressures, underscoring the role of forest cover in species persistence.

Bottom–up and top–down diversification: asymmetric processes over space and time

open access: yesOikos, Volume 2026, Issue 1, January 2026.
Coevolution in trophic interactions is often considered as a major factor underlying diversification in interacting species. Most focus hitherto has however been on bottom–up processes where host‐associated differentiation drives diversification, and less on top–down processes through enemy‐associated differentiation.

Establishment and rapid spread of social wasps (Hymenoptera: Vespinae) in Greenland Igutsaqalerneq igutsaqatigiiaartartullu (Hymenoptera: Vespinae) nunatsinni siaruaatipallannerat

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 247-252, January 2026.
In other island nations, the establishment of social wasps has had tremendous negative impacts on local biodiversity. The Red wasp Vespula rufa and the Norwegian wasp Dolichovespula norwegica have now been established in Greenland, with unknown impacts on native fauna.

Addressing Unmet Needs in Prurigo Nodularis: Expert Canadian Dermatology Perspectives

open access: yesDermatologic Therapy, Volume 2026, Issue 1, 2026.
Prurigo nodularis (PN) is a distinct chronic, inflammatory, neuroimmune‐mediated skin condition characterized by pruritic, often symmetrically distributed nodules, papules, and/or plaques. Recognition of PN as a distinct entity is complicated by the absence of a precise disease definition, uncertain epidemiologic estimates, and limited assessments of ...

Notes on Shifting Distribution Patterns and Survival of Immature \u3ci\u3eDanaus Plexippus\u3c/i\u3e (Lepidoptera: Danaidae) on the Food Plant \u3ci\u3eAsclepias Syriaca\u3c/i\u3e [PDF]

open access: yes, 2017
Abundance and distribution of immature stages of the monarch butterfly, Danaus plexippus, on the food plant Asclepias syriaca were examined at a site in southeastern Wisconsin over one growing season.

Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
The foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic. In this study, we ensure predators

Dynamical variations of the differential rotation in the solar convection zone

open access: yes, 2000
Recent analyses of helioseismological observations seem to suggest the presence of two new phenomena connected with the dynamics of the solar convective zone.
