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‐

How do insects pollinate flowers? Behaviour during visitation determines high pollination efficiency by a generalist insect

Functional Ecology, Volume 40, Issue 10, Page 3213-3224, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem services provide essential benefits to human survival and well‐being. Animal behaviour is central to the delivery of many ecosystem services, yet we know little about how behaviour drives services' provision.

Pollen landscape saturation on pollinator bodies reduces pollen deposition by subsequently visited bat‐pollinated flowers

Functional Ecology, Volume 40, Issue 10, Page 3190-3199, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual selection in flowering plants often operates through male–male competition, yet the mechanisms underlying this phenomenon remain difficult to demonstrate. One potential arena for such competition is pollen placement on pollinators, where pollen grains from ...

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

Ecological Entomology, Volume 51, Issue 5, Page 853-865, October 2026.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Influence of Mating Systems, Contemporary Niches, and Historical Demography on the Genetic Patterns of Flagship Plants From the Amazonian Cangas

Evolutionary Applications, Volume 19, Issue 10, October 2026.
ABSTRACT Genetic diversity is shaped by multiple factors, including life‐history traits, contemporary range distributions, niche constraints, and historical demography. The interplay of these drivers remains largely unexplored, particularly at scales proven to be relevant to conservation management of tropical biodiversity hotspots.
