Rapid Ocean Warming Drives Sexually Divergent Habitat Use in a Threatened Predatory Marine Ectotherm. [PDF]

Glob Chang Biol
How ectothermic, mobile marine predators are responding to climate change is uncertain due to lack of species‐specific data, which can mask the true impact of this threat. We investigate the impact of environmental conditions and thermal extremes on the behavior and distribution of angelsharks, a highly threatened elasmobranch of global conservation ...

Satellite sensor requirements for monitoring essential biodiversity variables of coastal ecosystems. [PDF]

Ecol Appl, 2018
Abstract The biodiversity and high productivity of coastal terrestrial and aquatic habitats are the foundation for important benefits to human societies around the world. These globally distributed habitats need frequent and broad systematic assessments, but field surveys only cover a small fraction of these areas.

Past human‐induced ecological legacies as a driver of modern Amazonian resilience

People and Nature, Volume 5, Issue 5, Page 1415-1429, October 2023., 2023
Abstract People have modified landscapes throughout the Holocene (the last c. 11,700 years) by modifying soils, burning forests, cultivating and domesticating plants, and directly and indirectly enriched and depleted plant abundances. These activities also took place in Amazonia, which is the largest contiguous piece of rainforest in the world, and for

Wildlife as sentinels of compliance with law: An example with GPS‐tagged scavengers and sanitary regulations

Journal of Applied Ecology, Volume 60, Issue 10, Page 2188-2198, October 2023., 2023
GPS‐tagged scavengers allow the on‐ground monitoring of carcasses, the addressing of potential risks for wildlife, livestock and human health, the quantitative assessment of compliance with the law and would improve estimates of carcass availability, substantially contributing to more effective legislation enforcement.

A comparative study on deep‐learning methods for dense image matching of multi‐angle and multi‐date remote sensing stereo‐images

The Photogrammetric Record, Volume 37, Issue 180, Page 385-409, December 2022., 2022
Among all stereo matching methods End‐to‐End (E2E) learning methods show that they can achieve the lowest and most frequent minimum errors, however, their performance drastically changes across different test‐sites, which indicates poor generalisation capabilities.

Using deep convolutional neural networks to forecast spatial patterns of Amazonian deforestation

Methods in Ecology and Evolution, Volume 13, Issue 11, Page 2622-2634, November 2022., 2022
Abstract Tropical forests are subject to diverse deforestation pressures while their conservation is essential to achieve global climate goals. Predicting the location of deforestation is challenging due to the complexity of the natural and human systems involved but accurate and timely forecasts could enable effective planning and on‐the‐ground ...

Large‐scale, image‐based tree species mapping in a tropical forest using artificial perceptual learning

Methods in Ecology and Evolution, Volume 12, Issue 4, Page 608-618, April 2021., 2021
Abstract Information about the spatial distribution of species lies at the heart of many important questions in ecology. Logistical limitations and collection biases, however, limit the availability of such data at ecologically relevant scales. Remotely sensed information can alleviate some of these concerns, but presents challenges associated with ...
