A Land Potential‐Based Framework for Wind Erosion and Sand and Dust Storm Source Mitigation

Land Degradation &Development, EarlyView.
ABSTRACT Wind erosion and sand and dust storms are a global challenge. While many management practices to mitigate sources of wind erosion and sand and dust storms have been documented, existing guidance largely emphasizes what practices are available, with limited information on where and under what ecological conditions they should be applied.

Desenvolvimento e produtividade de grãos de milho submetido a níveis de desfolha

Pesquisa Agropecuária Brasileira, 2015
O objetivo deste trabalho foi avaliar a influência da desfolha do milho no desenvolvimento e na produtividade de grãos. Seis ensaios foram conduzidos em diferentes safras e locais e em dois níveis de produtividade. Utilizou-se o delineamento de blocos ao

Bulbophyllum weddellii (Orchidaceae) demonstrates foliar water uptake plasticity along Brazilian campos rupestres

Nordic Journal of Botany, EarlyView.
Phenotypic plasticity can facilitate species survival in a variety of conditions that are not possible with a fixed phenotype. Foliar water uptake (FWU), defined as the absorption of water through leaf surfaces, is an important mechanism contributing to plant water balance and drought tolerance in many species.

Root biomass distribution in response to increasing active layer thickness across plant communities in a permafrost peatland

Nordic Journal of Botany, EarlyView.
In Arctic tundra, the majority of plant biomass is belowground. As temperatures increase and permafrost thaws, new soil volume containing nitrogen becomes available for plant roots, potentially leading to new plant–soil interactions. Whether or not different plant communities adapt their rooting depth distribution in response to increasing active layer

An extinction‐emergency metacollection: Maximising future recovery options for Rhodomyrtus psidioides (Myrtaceae), threatened by Myrtle Rust

PLANTS, PEOPLE, PLANET, EarlyView.
A challenge for wild plant conservation is the rising incidence of plant pathogens that are difficult to interdict, contain and manage. Invasive, fast‐moving, broad‐spectrum pathogens impose societal costs through losses of intrinsically valuable wild biodiversity, ecosystem function, current and potential genetic and biological assets, culturally ...

Responsible agrivoltaics in temperate Europe: Making systems work for plants, people, and climate

PLANTS, PEOPLE, PLANET, EarlyView.
Conceptual framework illustrating the three conditions for responsible AV in temperate regions: sustained plant productivity across rotations, preservation of soil and hydrological integrity, and social license for landscape integration. Multi‐site European evidence highlights how design choices shape trade‐offs among these dimensions.

Índice de Área Foliar em Caatinga Preservada

Conexões: Ciência e Tecnologia, 2016
O índice de área foliar (IAF) é um parâmetro biofísico que tem influência sobre vários processos ambientais, tais como fotossíntese, transpiração e balanço de radiação da superfície, sendo um importante parâmetro de entrada de modelos ecológicos.

The functional role of ants in no‐till cropping systems

Pest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.
