To provide pollinator nesting habitat, cut dead perennial stems in their first winter

open access: yesInsect Conservation and Diversity, EarlyView.
Garden management practises need to consider stem‐nesting bees and wasps to avoid destroying active nests and important nesting materials. Volunteers collected samples of dead stems (in situ where they grew) in winter, spring, summer and fall as part of a participatory research project.

Step by step: Floral structure and developmental changes to the formation of the gynostegium in Apocynaceae s.l.

open access: yesPlant Biology, EarlyView.
Developmental changes in Apocynaceae s.l. reveal progressive reductions in the corolla tube and epipetaly, together with increased staminal tube formation, highlighting shifts in floral integration associated with gynostegium evolution and organization.

Parasitoidism by Brachymeria pandora (Hymenoptera: Chalcididae) in Pupae of Danaus erippus (Lepidoptera: Nymphalidae) in an Urban Savanna Area

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT The Chalcididae comprises parasitoid wasps that attack various invertebrate groups. Within the family, some Brachymeria species specialises in infecting pupae of Lepidoptera. Here, we quantitatively describe the relationship between Brachymeria pandora and the Southern Monarch butterfly, Danaus erippus, in urban areas of Cuiabá, Mato Grosso ...

Cattle foraging on milkweed: Intra‐seasonal herbivory shifts and implications for monarch butterfly conservation

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Managing milkweed (Asclepias spp.) is of high conservation concern due to its association with monarch butterflies (Danaus plexippus L.), which are proposed for listing under the Endangered Species Act. To counteract monarch declines, conservation goals aim to establish ≥1.6 billion nonagricultural milkweed stems within the Midwestern United ...

Henry Trimen: Under‐appreciated pioneer in the typification of Linnaean plant names?

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract In 1887, Henry Trimen published a paper summarising the contents of the Hermann Herbarium, in what is now the Natural History Museum, London (BM), in terms of the plant names published by Linnaeus. Trimen referred to the Hermann specimens as types of Linnaeus's names.

Foliar Contributions to Methane and Nitrous Oxide Exchange in Urban Green Roof Systems

open access: yesGCB Bioenergy, Volume 18, Issue 6, June 2026.
Biochar amendment of extensive green roof substrates enhanced foliar methane (CH4) uptake (~3×) and reduced nitrous oxide (N2O) emissions across native and stonecrop vegetation. City‐scale extrapolation to Toronto's permitted green roof area indicates measurable, management‐sensitive non‐CO2 mitigation within urban green infrastructure systems ...
