Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

open access: yesNew Phytologist, EarlyView.
Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

No evidence of a decoy effect in bees: Rewardless flowers do not increase bumblebees' preference for neighbouring flowers

open access: yesEcological Entomology, Volume 51, Issue 4, Page 799-809, August 2026.
Many plants retain nectarless flowers; we tested whether these act as “decoys” for bees by making neighbouring rewarding flowers seem more valuable—a cognitive bias known as the decoy effect. The presence of decoy flowers did not shift bumblebee preferences between two equally rewarding inflorescences, and bees quickly learned to avoid these nectarless

Hoverfly (Diptera: Syrphidae) diversity in Tapada da Ajuda, Lisbon - a preliminary study

open access: yes, 2018
Hoverflies are holometabolic insects, whose adults are pollinators feeding on nectar and pollen. Frequently, they are confused with wasps, bees and bumblebees.

Effects of artificial diets and floral nectar on longevity and progeny production of Trichogramma euproctidis Girault (Hymenoptera: Trichogrammatidae)

open access: yes, 2012
Trichogramma species are the most widely used biological control agents against lepidopteran pests. They prefer sugar-based substances as foods, especially plant nectar.

Mothbox and Mothbot: Automated light trap and data processing system for scalable insect monitoring

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 7, Page 2082-2091, July 2026.
Abstract Insects represent the most diverse group of organisms on Earth and comprise the majority of known species; yet they are seldom accounted for in large‐scale biodiversity monitoring systems and conservation planning. We have developed the Mothbox—an open source automated light trap that makes insect monitoring accessible to non‐specialists and ...

Refining generic limits in Hyacinthinae (Asparagaceae, Scilloideae): Conflict and concordance between morphology and phylogenomics

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 4, Page 751-775, July 2026.
Using Angiosperms353 and plastid genome skimming, the generic limits of Hyacinthinae were explored. Floral morphology conflicts with the molecular groupings in many cases, but bulb morphology and cytogenetics define groups similar to those defined by DNA.

Digitised herbarium specimen data reveal a climate change‐related trend to an earlier, shorter Canadian Arctic flowering season, and phylogenetic signal in Arctic flowering times

open access: yesNew Phytologist, Volume 251, Issue 2, Page 696-706, July 2026.
Summary The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved.
