Efficient and Accurate Spatio‐Temporal Population Monitoring of Mobile Animals Using Drones and Computer Vision

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Drones and computer vision offer an efficient way to estimate animal populations over localized areas, but surveys often require stitching many overlapping images together. If animals move during the survey, traditional orthomosaic‐based counting methods become unreliable, with some animals appearing in multiple locations while others appear not at all,

A Tracking‐By‐Detection Framework to Automatically Count Rare and Elusive Megafauna in Aerial Video Surveys

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Monitoring programs of vulnerable megafauna increasingly rely on aerial surveys from drones or planes fitted with cameras. However, automated methods are still lacking to accurately count individuals across entire surveys. Here, we leverage a tracking‐by‐detection framework to not only detect individuals but also link the resulting detections across ...

Improving Demographics and Conservation of Fishes Through Multi‐Frame Individual Distinctions by Size (MIDS)

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
MIDS (Multi‐frame Individual Distinctions by Size) is a new software package for improving how fish populations are assessed using stereo‐video data. By using the length, error and statistical inference of measurements, MIDS distinguishes individuals across multiple video frames and autonomously removes repeat observations, regardless of when the ...

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

open access: yesSustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Prescriptive Positivism: Discourse on Sustainable Development Goal Interactions and Perspectives for a Post‐2030 World

open access: yesSustainable Development, EarlyView.
ABSTRACT The Sustainable Development Goals (SDGs) are unlikely to be achieved by 2030, prompting debate about what should follow. Beyond revision, there is a need to critically examine what values and assumptions have shaped how the SDGs are conceptualised and operationalised.
