Assessing group size and the demographic composition of a canopy‐dwelling primate, the northern muriqui (Brachyteles hypoxanthus), using arboreal camera trapping and genetic tagging

Remote Sensing in Ecology and Conservation, EarlyView.
We combined arboreal camera trapping and non‐invasive genetic tagging to estimate group size in the critically endangered northern muriqui (Brachyteles hypoxanthus) in Brazil's Atlantic Forest. Both methods provided complementary insights into group size and demographic structure, while differing in their cost‐effectiveness and sampling constraints ...

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.

From snapshots to continuous estimates: Augmenting citizen science with computer vision for fish monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents an end‐to‐end computer‐vision pipeline for monitoring fish migration using underwater video. We integrate field camera deployment, annotation, model training and automated in‐season counting to generate continuous, high‐resolution data on river herring spawning migration.

Urban Forests and Environmental Challenges in the Last Decades in Brazil: Insights for the National Urban Forestry Plan

Sustainable Development, EarlyView.
ABSTRACT National afforestation policies are crucial for outlining guidelines and goals to be implemented at the local level. Therefore, it is crucial to conduct research that systematizes indicators from across the country into a single proposal. This study examines the spatiotemporal distribution of urban forest research in Brazil from 1980 to 2020 ...

Tropical Forests and Sustainability: The Role of Multilateral Financing in Latin America

Sustainable Development, EarlyView.
ABSTRACT The challenge of slowing deforestation and degradation in the tropical regions of Latin America requires financing mechanisms (public and private) that can enable actions to preserve and sustainably manage forest integrity. This paper begins by examining the strategy implemented by the World Bank to protect forest cover in tropical countries ...

Large females connect Atlantic cod spawning sites

Science, 2023
The Earth’s ecosystems are increasingly deprived of large animals. Global simulations suggest that this downsizing of nature has serious consequences for biosphere functioning. However, the historical loss of large animals means that it is now often impossible to secure empirical data revealing their true ecological importance.

Hypoxia tolerance in Atlantic cod

Journal of Fish Biology, 1998
Oxygen saturation levels that killed 50 and 5% of cod Gadus morhua over 96 h averaged 21·2 and 27·7%, respectively. No fish survived at 10% saturation and only a few survived at 16% saturation, whereas no mortality occurred at 34 and 40% oxygen saturation. Since metabolic rate and oxygen consumption increase with increasing temperature, we hypothesized

Farmed Atlantic Cod

Journal of Food Products Marketing, 2007
This paper reports a study of quality perceptions and atti- tudes towards farmed cod amongst 90 chefs in up-market restaurants in England, Norway and Spain. Findings show that the chefs perceived the quality of farmed cod as favourable. More specifically, survey results show that product attributes such as freshness, texture of flesh, skin col- our ...
