Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

Journal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

Using recommender systems to analyze and predict plant communities from partial assemblages

Ecological Monographs, Volume 96, Issue 1, February 2026.
Abstract Safeguarding biodiversity requires a detailed understanding of the biosphere, especially regarding the distribution and state of habitats. Citizen science data offer a rich source of useful information, but they usually only contain partial records of species assemblages, as predominantly opportunistic observations of individual species are ...

Regeneração de espécies nativas lenhosas sob plantio de Eucalyptus em área de Cerrado na Floresta Nacional de Paraopeba, MG, Brasil Regeneration of wood natives species under Eucalyptus stand of Cerrado area in the Floresta Nacional of Paraopeba, Minas Gerais, Brazil

Acta Botânica Brasílica, 2005
A regeneração de sub-bosques em plantios homogêneos tem estreita dependência de florestas vizinhas. Outros fatores exercem influência, como a ecologia da dispersão da espécie, os efeitos de borda e clareiras.

Impact of Pre‐Emergent Herbicides and Soil Management on Weed Community Dynamics and Soybean Yield

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Pre‐emergent herbicides are key tools in managing herbicide‐resistant and hard‐to‐control weed species in soybean (Glycine max L.) cultivation. This study aimed to evaluate the effects of pre‐emergent herbicides on weed phytosociology, soybean phytotoxicity, and grain yield under different soil management systems and environmental conditions.

Relationship among grain-size, plant communities, and fluvial and eolian processes in a piedmont of the central Andes in Argentina

Ecología Austral, 2003
The relationship among modern geomorphological processes, grain-size of surface sediments, and vegetation was analyzed in an alluvial fan in the piedmont of the Cordillera Frontal (Andes Mountains). Statistical parameters of grain-size distribution were

Levantamento fitossociológico de plantas daninhas na cultura do girassol Phytosociological survey of weeds in sunflower crop

Planta Daninha, 2010
O levantamento fitossociológico da comunidade de plantas daninhas na cultura do girassol foi realizado em duas épocas distintas: no desenvolvimento inicial da cultura (entre 20 e 40 dias após a semeadura) e na pré-colheita do girassol.

Contribution of SPOT-7 multi-temporal imagery for mapping wetland vegetation

European Journal of Remote Sensing, 2020
Mapping the fine-grained pattern of vegetation is critical for assessing the functions and conservation status of wetlands. Although satellite time-series images can accurately model vegetation, the spatial resolution of these data is generally too ...
