Testing macroevolutionary predictions of the Grant‐Stebbins model in the origin of Aeschynanthus acuminatus

open access: yesNew Phytologist, EarlyView.
Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.

Influence of drought stress on the metabolite and ion composition in nectar and nectaries of different day‐ and night‐flowering Nicotiana species

open access: yesPlant Biology, EarlyView.
Drought stress leads to reduced nectar secretion and alters nectar composition of day‐ and night‐flowering Nicotiana species, which may impair plant–pollinator interactions. Abstract The frequencies of droughts worldwide will increase in the future due to climate changes. Nectar composition of plant species varies in relation to pollinator and can also

Differences in vocal brain areas and astrocytes between the house wren and the rufous-tailed hummingbird

open access: yesFrontiers in Neuroanatomy
The house wren shows complex song, and the rufous-tailed hummingbird has a simple song. The location of vocal brain areas supports the song’s complexity; however, these still need to be studied.

Images Assisting Wor[l]ds: Black History Murals in South and West Philadelphia

open access: yesSociological Forum, EarlyView.
ABSTRACT Black history murals are often understood as examples of state or corporate obfuscation of racial inequality, sometimes known as “artwashing”; or, conversely, as “insurgent” political interventions. Focusing on murals in historically Black neighborhoods in South and West Philadelphia, this article instead highlights the processual, but no less

Flowers visited by hummingbirds in the open habitats of the southeastern brazilian mountaintops: species composition and seasonality

open access: yesBrazilian Journal of Biology
The hummingbird-visited plant community located on the open-habitat mountaintop of the Espinhaço Range was studied for two years (from August 2007 to July 2009) in Serra do Cipó National Park, Southeastern Brazil (19° 15′ S and 43° 31′ W).

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

open access: yesBiological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...
