Bract size affects resource availability and fruit set in a hummingbird‐pollinated plant with distyly polymorphism

open access: yesPlant Biology, EarlyView.
In Psychotria poeppigiana, larger bracts honestly signal greater nectar availability but have higher mortality, while smaller bracts produce more fruit, revealing a surprising trade‐off and hints of sexual role specialization in this distylous species. Abstract Plants can use non‐floral signals to advertise the presence of resources to pollinators. The

Combined effects of soil multi‐contamination by metals and metalloids and drought slow down the ecological restoration of a Mediterranean scrubland

open access: yesRestoration Ecology, EarlyView.
In Mediterranean ecosystems, soil contamination by metals and metalloids and drought represent major abiotic stresses whose combined effects on plant communities remain poorly understood, hindering effective ecological restoration practices. Here we evaluated the responses of plant community and species to combined stresses during a 4‐year ecological ...

The bumble bees (Hymenoptera: Apidae: Bombus) of Arkansas, fifty years later [PDF]

open access: yes, 2015
Many species of bumble bees (Hymenoptera: Apidae: Bombus Latreille) are declining throughout their ranges in North America, yet detecting population trends can be difficult when historical survey data are lacking.  In the present study, contemporary data

Paving the Way for Rearing Closterocerus coffeellae: Effect of Adult Food Source and Oviposition Behavior in Leucoptera coffeella

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1226-1235, November 2025.
This study evaluated food sources for adult Closterocerus coffeellae survival and oviposition behavior. Adults were fed honey (10%), Hibiscus nectar, an artificial diet, or received no food. Male survival was higher on the artificial diet, whereas honey (10%) increased female survival.

Spatial Patterns of Genomic Variation and Genomic Offset in a Common Grassland Plant and Their Relation to Seed Transfer Zones

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Analysis of the genetic structure of Galium album, a widespread grassland species, across Germany revealed four spatially coherent genetic clusters that showed little congruence with current seed transfer zones, though zones still captured significant spatial genetic structure.
