Testing for apomixis in an obligate pollination mutualism
Journal of Pollination Ecology, 2021 Plants with a small number of specific pollinators may be vulnerable to fluctuations in the availability of those pollinators, which could limit plant reproductive success and even result in extinction. Plants can develop mechanisms to mitigate this risk,

Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination
Journal of Integrative Plant Biology, EarlyView.Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.

Floral Scent Chemistry and Pollinators of a Sexually Dimorphic Neotropical Orchid
Plants, 2022 Catasetum is a speciose Neotropical orchid genus of which male and female flowers emit scents acting both as attractant and reward for their exclusive pollinators, male orchid bees (Euglossini: Apidae). In Catasetum, it is well known that flowers display

Edaphic isolation as a driver of divergence in a new Amazonian species of Diclinanona (Annonaceae)
TAXON, Volume 75, Issue 3, June 2026.Abstract For many years a mysterious collection made during an expedition to Venezuelan Amazonia in 1992 was in a folder at the former Utrecht Herbarium as “unidentified Annonaceae”. Several different genera were suggested for identification but since flowers were lacking it was unclear where this taxon should be placed. One of the suggestions based on
