Non‐floral scent sources of orchid bees: Observations and significance

open access: yesBiotropica, Volume 57, Issue 1, January 2025.
We observed male euglossines collecting scent at 21 different non‐floral sources in Central and South America, strengthening the view that these sources play a central role in euglossine perfume biology. A Protium tree provided over 50% of the perfumes for Eufriesea corusca and was repeatedly revisited.

open access: yes, 2017
Anurans employ a wide variety of anti-predator mechanisms to defend themselves. In casque-headed hylids, defence is thought to be a complex combination of several anti-predator mechanisms. However, the defence traits of only a few species are known; some

Flagellate protist abundance in phytotelmata of Aechmea distichantha Lem. (Bromeliaceae) in the upper Paraná river basin - doi: 10.4025/actascibiolsci.v35i4.17134

open access: yesActa Scientiarum: Biological Sciences, 2013
In some Bromeliaceae species the leaf sheaths form a tank or phytotelma, accumulating water and organic detritus, conditions that allow the establishment of different communities. Thus, this study evaluated the relationship between diameter and volume of

The male germ unit association is independently regulated of GUM in Arabidopsis thaliana

open access: yesPlant Direct, Volume 8, Issue 7, July 2024.
Abstract Cytoplasmic projections (CPs) formed by the generative and sperm cells link the male gametes with the vegetative cell (VC) nucleus, which are required to build the male germ unit (MGU) assemblage in the angiosperm pollen grain. As molecular and genetic controls underlying CP development and formation of the MGU are unknown, it was hypothesized
