A new method to control the invasive sun corals (Tubastraea spp.): Underwater compressed‐air blasting

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater compressed‐air blasting is a novel method developed to control invasive sun corals (Tubastraea spp.). The technique removes coral soft tissue without fragmenting colonies, reducing the risk of regeneration and accidental spread. This approach offers a safer and practical tool for managing invasive corals in natural reefs and biofouling ...

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.

Determination of Paraquat in Real Samples Using a Printed PET‐Based Electrode Modified With Molecularly Imprinted Polymer and Carbonaceous Material

open access: yesElectroanalysis, Volume 37, Issue 12, December 2025.
This study reports the development of an electrochemical sensor printed with graphite‐based ink on a recycled PET substrate. The device was functionalized with a molecularly imprinted polymer (MIP) and multiwalled carbon nanotubes (MWCNTs) for the selective detection of paraquat in water, apple juice, and acerola juice samples, highlighting its ...

When Raptors Are Away, Opossums Will Play: Woolly Opossums as Carrion Feeders in Harpy Eagle Nests

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
Scavenging by New World marsupials is rarely documented. We recorded woolly opossums (Caluromys lanatus) scavenging prey remains from a Harpy eagle’s nest in central Brazil. The low overlap in activity periods between the two species may facilitate the behavior observed here.

catalogoUCsBR: A new R package and application for creating comprehensive plant species lists for Brazilian Protected Areas

open access: yesApplications in Plant Sciences, Volume 13, Issue 5, September-October 2025.
Abstract Premise The increased online publication of data associated with Brazilian botanical collections and biodiversity information systems has significantly improved access to information on plant species occurring in Brazil. However, information about Brazilian flora within Protected Areas is fragmented.

Insights on the Potential of Natural Regeneration to Restore Cerrado Open Ecosystems

open access: yesAustral Ecology, Volume 50, Issue 9, September 2025.
The colonisation potential of native Cerrado species in degraded areas will depend on the remaining underground structures and not on seed rain from nearby conserved remnants. Effective restoration of the Cerrado will not be possible without active restoration, if the bud‐bank are not present in the system.
