Cross‐regional and temporal generalizability of portable visible spectroscopy for olive maturity classification

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Olive maturity governs lot destination and the yield–quality trade‐off in olive oil production, yet it is still monitored by subjective visual scoring of the Jaén index. Spectroscopic alternatives have relied mainly on near‐infrared instruments, with scarce evidence from Brazilian orchards and almost no evaluation of spatial or ...

How many bromeliads are there? History and future perspectives of species scientific discovery in the pineapple family

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
It remains unclear how many plant species are not yet recorded by science. We illustrated the process by which species of the pineapple family in tropical America have been newly described to science to date, and we estimated how many species may still await scientific discovery in this group.

Dinâmica da cobertura florestal na Serra da Mantiqueira entre 1999 e 2017

open access: yesGEOGRAFIA (Londrina), 2020
Apesar da extensa cobertura florestal nativa, usos como pastagem extensiva e cultivo florestal também estão presentes na Área de Proteção Ambiental da Serra da Mantiqueira (APA-SM). Além disto, há também ausência de um plano de manejo, com pouco estudo ambiental sobre sua dinâmica de uso e ocupação.

Mulching does not improve seedling survival or growth during early forest restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Weed control is one of the main operational challenges and cost components of tropical forest restoration in former pasturelands. Physical barriers (mulches) have been proposed as an alternative to conventional ring weeding because they can suppress competing vegetation while potentially improving the soil microenvironment ...

Present and Future Distribution of Apochloa molinioides and Trichanthecium wettsteinii in the Brazilian Campos Rupestres: Ecological Modeling for Climate‐Smart Conservation

open access: yesBiotropica, Volume 58, Issue 6, November 2026.
ABSTRACT High‐elevation ecosystems are among the most sensitive to climate change, responding more rapidly than low‐elevation environments. However, few studies have shown the effects of climate change on grass species in these environments. Among them, Apochloa molinioides and Trichanthecium wettsteinii (Poaceae) are notable for occurring in high ...
