Fish Migration Through Ship Locks at the Danube River, Austria

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Longitudinal connectivity in the Austrian section of the Danube has improved over the last three decades thanks to the progressive installation of fish passage facilities at hydropower plants. However, navigation locks which are present at all barrages remain poorly quantified with respect to their role in fish migration.

Daylight performance evaluation in residential environments

open access: yes, 2019
A utilização da luz natural contribui com a redução do uso de iluminação artificial em ambientes internos. Esta pesquisa tem como objetivo avaliar o desempenho da luz natural em ambientes de cozinha e de área de serviço de residências multifamiliares com diferentes configurações espaciais na cidade de Porto Alegre – RS, por meio dos critérios da NBR ...

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Inferring Brown Bear Hair Snare Interactions by Automatically Detecting Bipedalism on Camera Trap Images Using Pose Estimation and a Multilayer Perceptron

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study proposes an automated method to infer brown bear hair snare interactions by detecting bipedal behavior in camera‐trap images using a pose estimation model and a multilayer perceptron (MLP). A YOLO‐based model, fine‐tuned from humans and dogs to a custom dataset, achieved high performance (≈93% keypoint precision and ≈96% classification ...

Development and Evaluation of a Low‐Cost, Semi‐Automated Camera Trap for Surveying Bumble Bee Communities

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera traps are emerging as a useful tool for noninvasive insect monitoring; however, it remains unclear how to lure diurnal insects to traps, how to detect them upon arrival, and how camera‐based methods compare to conventional sampling. We developed a low‐cost, open‐source camera trap to monitor wild bumble bees in agricultural fields. We found that
