Relação entre heterogeneidade ambiental e distribuição de espécies em uma floresta paludosa no Município de Cristais Paulista, SP, Brasil Floristic composition and relationship between environmental heterogeneity and species distribution in a swamp forest from Cristais Paulista, São Paulo State, Brazil

Acta Botânica Brasílica, 2009
Neste estudo foi caracterizada a composição florística e fitossociológica de uma floresta paludosa no nordeste do Estado de São Paulo, onde variações no padrão de drenagem ocorrem principalmente no sentido perpendicular ao curso d'água, em função da ...

Comparative Assessment of Landsat‐8 and SPOT‐7 Satellite Data With Field Spectral Measurements for Estimating Plant Diversity in Sandy Grasslands

Biological Diversity, EarlyView.
We compared Landsat‐8 OLI, SPOT, and hyperspectral data for estimating vascular plant diversity in China's Hunshandak Sandland. SPOT data showed the strongest correlation with alpha diversity, followed by hyperspectral data, with Landsat‐8 performing the weakest.

Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

Remote Sensing in Ecology and Conservation
Secondary forests in the Amazon are important carbon sinks, biodiversity reservoirs, and connections between forest fragments. However, their regrowth is highly threatened by fire.

Deforested tropical landscapes: Unveiling the mechanisms driving tree saplings growth and survival in forest fragments

Global Ecology and Conservation
Forest loss poses a critical threat to biodiversity, with species’ ecological traits shaping their sensitivity to anthropogenic disturbances. Forest specialists, such as shade-tolerant plants, are especially vulnerable to local extinction, whereas shade ...

Differential Elevational Diversity Between Overstory and Understory in Tropical Forests

Biological Diversity, EarlyView.
Tropical forest overstory and understory exhibit contrasting elevational α‐diversity patterns (unimodal vs. bimodal). Community differentiation is driven by species turnover of dominant rather than rare species, highlighting the need for vertically stratified conservation across the full elevational gradient.

Changes in planned and unplanned canopy openings are linked in Europe’s forests

Nature Communications
AbstractCanopy openings are increasing in Europe’s forests, yet the contributions of anthropogenic and ecological agents of disturbance to this increase remain debated. Here we attribute the root cause of all stand-replacing canopy disturbances identified for Europe in the period 1986–2020 from Landsat data (417,000 km²), distinguishing between planned

Mobile Open-Source Plant-Canopy Monitoring System

Modern Instrumentation, 2017
Many agricultural applications, including improved crop production, precision agriculture, and phenotyping, rely on detailed field and crop information to detect and react to spatial variabilities. Mobile farm vehicles, such as tractors and sprayers, have the potential to operate as mobile sensing platforms, enabling the collection of large amounts of ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...
