AVALIAÇÃO DA VARIAÇÃO ESPECTRAL DO CERRADO POR SENSOR REMOTO PASSIVO [PDF]

REVISTA ENGENHARIA NA AGRICULTURA - REVENG, 2019
O Cerrado é a segunda maior cobertura vegetal natural do Brasil, perfazendo cerca de 23% da área total, localizado na maioria de sua extensão no Planalto Central Brasileiro. Para a análise do Cerrado é utilizado o sensoriamento remoto, que está amplamente aplicado para o monitoramento de coberturas vegetais, e principalmente avaliando o desempenho ...

Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Reliability of MODIS Evapotranspiration Products for Heterogeneous Dry Forest: A Study Case of Caatinga

Advances in Meteorology, Volume 2017, Issue 1, 2017., 2017
Evapotranspiration (ET) is normally considered as the sum of all water that evaporates from the soil and transpires from plants. However, accurately estimating ET from complex landscapes can be difficult because of its high spatial heterogeneity and diversity of driver factors, which make extrapolation of data from a point to a larger area quite ...

Using accelerometer‐based behavioural classification to enhance scavenger conservation

Journal of Applied Ecology, Volume 62, Issue 11, Page 2987-3004, November 2025.
We provide a tool to help identify vulture feeding hotspots, supporting carcass management efforts to prevent poisoning. Integrated with near real‐time tracking, our model can support global efforts to combat scavenger poisoning. The training dataset, model and codes are provided in a user‐friendly platform, along with a conceptual framework, to ...

Swell and Wind‐Sea Distributions over the Mid‐Latitude and Tropical North Atlantic for the Period 2002–2008

International Journal of Oceanography, Volume 2012, Issue 1, 2012., 2012
We present an analysis of wind‐sea and swell fields for mid‐latitude and tropical Atlantic for the period 2002–2008 using a combination of satellite data (altimeter significant wave height and scatterometer surface winds) and model results (spectrum peak wave period and propagation direction).

Unexpected soundscape response to insecticide application in oak forests

Conservation Biology, Volume 39, Issue 3, June 2025.
Abstract Rachel Carson's warning of a silent spring directed attention to unwanted side effects of pesticide application. Though her work led to policies restricting insecticide use, various insecticides currently in use affect nontarget organisms and may contribute to population declines.

Too much and not enough data: Challenges and solutions for generating information in freshwater research and monitoring

Ecosphere, Volume 16, Issue 3, March 2025.
Abstract Evaluating progress toward achieving freshwater conservation and sustainability goals requires transforming diverse types of data into useful information for scientists, managers, and other interest groups. Despite substantial increases in the volume of freshwater data collected worldwide, many regions and ecosystems still lack sufficient data
