A fish-based multimetric index for Brazilian savanna streams

Ecological Indicators, 2017
Abstract Multimetric indices (MMI) have been widely used to assess ecosystem conditions because they are low-cost, employ a rapid field method, and can incorporate various biological metrics at different levels of biological organization. Our objective was to create a fish-based multimetric index applicable to all streams of the Brazilian savanna ...

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

The inadequacies of the steppic savanna classification system to describe the vegetation of the semi-arid Caatinga of Brazil [PDF]

Rodriguésia
The steppic savanna term was originally employed to classify a single type of tropical vegetation in Africa, but it has been expanded by the pioneering RADAMBRASIL authors and it is currently used to classify the vegetation of the Caatinga in ...

Persistence and potential of soil organic carbon in nature‐based climate solutions: A review of managed disturbances

PLANTS, PEOPLE, PLANET, EarlyView.
Implementing nature‐based climate solutions is important for mitigating climate change, which is a global issue, but requires local adjustments in management practices. Using the association between soil carbon and minerals as a proxy for carbon persistence, we evaluated the effect of different management regimes on soil carbon sequestration and loss ...

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

Remote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.

How do males of Hypsiboas goianus (Hylidae: Anura) respond to conspecific acoustic stimuli?

Zoologia (Curitiba), 2015
Acoustic communication plays an important role in the social behavior of anurans. Acoustic signals, which can be used in different contexts such as mate attraction and territory defense, may mediate social interactions among individuals.

Mapping the Brazilian savanna’s natural vegetation: A SAR-optical uncertainty-aware deep learning approach

ISPRS Journal of Photogrammetry and Remote Sensing
The Brazilian savanna (Cerrado) is considered a hotspot for conservation. Despite its environmental and social importance, the biome has suffered a rapid transformation process due to human activities. Mapping and monitoring the remaining vegetation is essential to guide public policies for biodiversity conservation.

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the
