Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

Oikos, Volume 2026, Issue 4, April 2026.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

IUCN Red List Regional Assessment of the Flora of Niue Utilising Indigenous Local Knowledge and Botanical Information

Journal of the Royal Society of New Zealand, Volume 56, Issue 2, April 2026.
A regional assessment of the indigenous vascular plants of Niue is presented using the IUCN Red List criteria. The assessment was undertaken during a community workshop that drew on the indigenous local knowledge and scientific information. The assessment comprised 197 named taxa and 8 indeterminate entities, with 4 (2.0%) taxa assessed as Extinct and ...

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

TAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Tetraopes Milkweed Beetle Genomes Elucidate the Adaptive Basis of a Temperate Coevolutionary Radiation

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Biogeographic History and Morphological Trait Influence in the Diversification of the Subtribe Calothecinae (Poaceae)

Journal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim The biodiversity of the Neotropics has been shaped by complex interactions over time with several major geological and climatic events linked to the diversification of lineages. The subtribe Calothecinae (Poaceae) comprises 28 species adapted to open environments, ranging from lowlands to high‐altitude grasslands in America.
