Methods in Ecology and Evolution, Volume 14, Issue 10, Page 2549-2556, October 2023., 2023 Abstract Ecologists are now widely utilising video data to quantify the behaviours and interactions of animals in the wild. This process can be facilitated by collecting videos in stereo, which can provide information about animals' positions, movements and behaviours in three‐dimensions (3D).

Methods in Ecology and Evolution, Volume 14, Issue 7, Page 1699-1707, July 2023., 2023 Abstract Computer programs for video tracking of animal movement are evolving increasingly efficient, using complex algorithms or artificial intelligence systems. Despite the consequent progress in this field, researchers still face some fundamental problems in the use of such programs. For example, the best‐performing programs are often uneasy to use,

Digest of Middle East Studies, Volume 31, Issue 4, Page 359-379, Fall 2022., 2022 Abstract This paper examines the impact of informal quotas on the substantive representation of women in appointed upper parliaments using the Omani State Council as a case study. Although no formal gender quota has been institutionalized in Oman, it is presumed that the Sultan will assign 17% of the seats to women, effectively an informal quota ...

The Photogrammetric Record, Volume 37, Issue 179, Page 285-305, September 2022., 2022 This paper aims to study and quantify the induced error due to the deflection of verticals (DOV) when integrating different sensors, focusing on GNSS and INS for 3D mapping in airborne mapping. It is shown that the DOV effect should be considered for direct georeferencing because the DOV components are in the order of (or larger than) INS uncertainty ...

Relative Radiometric Normalisation of Unmanned Aerial Vehicle Photogrammetry‐based RGB Orthomosaics
The Photogrammetric Record, Volume 37, Issue 178, Page 228-247, June 2022., 2022 This article deals with the problem of varied brightness of UAV images caused by the changing weather conditions. Relative radiometric normalization (RRN) of acquired RGB imagery is used to improve the visual quality of the resultant orthomosaic. The algorithm utilizes image positions and their relationships to group them, choose references, and ...

Assessing the camera trap methodologies used to estimate density of unmarked populations
Journal of Applied Ecology, Volume 58, Issue 8, Page 1583-1592, August 2021., 2021 Our results show that all of the methods examined can work well, with each having particular strengths and weaknesses. Broadly, Random Encounter and Staying Time (REST) could be recommended in scenarios of high abundance, Distance Sampling with camera traps (CT‐DS) in those of low abundance while Random Encounter Model (REM) can be recommended when ...

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.We assessed the acceptability and consumption of a custom‐developed nicarbazin bait for feral pigeons, inferred its contraceptive efficacy, and evaluated the reversibility of its effects upon cessation of treatment. Only feral pigeons consumed the bait, except for one eared dove that also ingested the food. Continuous administration of this bait raised
