Evaluating endophyte‐rich leaves and leaf functional traits for protection of tropical trees against natural enemies

open access: yesFunctional Ecology, Volume 39, Issue 2, Page 371-389, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants use physical barriers and chemical compounds to defend themselves against natural enemies. For instance, tough leaves are considered to be better defended than soft leaves, part of a spectrum of defences defined by functional traits such as leaf chemistry ...

Discreet but diverse and specific: Determining plant‐herbivore interactions across a species‐rich plant family in a tropical rain forest

open access: yesBiotropica, Volume 57, Issue 1, January 2025.
We conducted a year‐long study in Ecuador's Yasuní National Park, focusing on nine understory Annonaceae species to investigate herbivory patterns and herbivore‐host associations. Our findings revealed significant temporal fluctuations in leaf damage, with Anaxagorea brevipes and Unonopsis veneficiorum experiencing higher herbivore pressure, and ...

Study of DNA damage induced by dental bleaching agents in vitro Estudo de danos no DNA induzidos por agentes clareadores dentais in vitro

open access: yesBrazilian Oral Research, 2006
Dental bleaching is a simple and conservative procedure for aesthetic restoration of vital and non-vital discolored teeth. Nevertheless, a number of studies have demonstrated the risk of tissue damage from the contact of these agents with the oral mucosa.

High tolerance to zinc but no evidence for local adaptation in the aquatic plant Lemna minor

open access: yesNordic Journal of Botany, Volume 2024, Issue 7, July 2024.
Duckweeds are a widely distributed and economically important aquatic plant family that have high potential for phytoremediation of polluted water bodies. We collected four ecotypes of the common duckweed Lemna minor from the four corners of Switzerland and assessed how their home versus away environments influenced their growth.

Resposta a danos no DNA após exposição à luz ultravioleta: apagando o fogo antes do incêndio celular

open access: yesRevista da Biologia, 2015
DNA is a reactive molecule and it is estimated that more than 20 thousand lesions are induced endogenously per cell per day, besides other induced by exogenous agents such as ultraviolet light exposure, resulting in physical blockage of DNA replication and transcription machineries.
