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.

Contrasting microbial communities on male and female flowers of a dioecious plant, Mallotus japonicus (Euphorbiaceae)

Environmental DNA, 2022
Flowers play a central role in plant reproduction by dispersing and receiving pollen grains delivered by animal vectors or air. They are rich in various nutrients, and therefore, provide an ideal habitat for many microbes.

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

Zoologica Scripta, Volume 55, Issue 6, Page 830-845, November 2026.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

A model for the gradual evolution of dioecy and heterogametic sex determination

bioRxiv
In plants with separate sexes, the development of an individual as male or female is controlled by a dominant allele at a sex-determining locus - the fundamental basis of XY and ZW systems.

Molecular phylogeny, biogeography, and taxonomy of Afro‐alpine Poa species of sub‐Saharan Africa and Madagascar

TAXON, Volume 75, Issue 5, October 2026.
Abstract We conducted phylogenetic analyses of Poa focused on Afro‐alpine species from sub‐Saharan Africa and Madagascar. We analyzed three plastid regions (matK, trnC‐rpoB, trnT‐trnL‐trnF) and two nuclear ribosomal (nr) regions (ITS, ETS) for 194 samples and 117 species of Poa. We present new DNA data for 93 samples, including 33 samples of seven Afro‐

Caracterização funcional do sistema reprodutivo da aroeira-vermelha (Schinus terebinthifolius Raddi), em Florianópolis-SC, Brasil Characterization of the functional reproductive system of the pink-pepper (Schinus terebinthifolius Raddi), in Florianópolis, SC, Brazil

Revista Brasileira de Fruticultura, 2004
Determinou-se a dioicia como sistema reprodutivo de S. terebinthifolius (Anacardiaceae), em uma área com influência antrópica e em outra área de restinga, no município de Florianópolis-SC.

Generalist passerine birds perform a functional role as pollinators in temperate Europe

Journal of Ecology, Volume 114, Issue 7, July 2026.
Nectar‐feeding birds are effective pollinators. In temperate Europe, songbirds visit flowers but lack specialist traits, so functional pollination has been discounted. We use observations, pollen identification and experiments to demonstrate that generalist birds affect fruit‐set of flowering trees.

Recent Sex Chromosome Divergence despite Ancient Dioecy in the Willow Salix viminalis

Molecular biology and evolution, 2017
Sex chromosomes can evolve when recombination is halted between a pair of chromosomes, and this can lead to degeneration of the sex-limited chromosome.

Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

New Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...
