Wildlife Biology, EarlyView.This research paper investigates the efficacy of leading machine learning (ML) models for detecting and identifying ungulate species in African savanna using nadir imagery from unmanned aerial vehicles (UAVs). Traditional aerial counting methods, while widely used, suffer from significant limitations in accuracy and precision, in part due to human ...

Experimental assessment of large mammal population estimates from airborne thermal videography
Wildlife Biology, EarlyView.Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.

Ed Davey's Tory Removals: The Liberal Democrats and the 2024 General Election
The Political Quarterly, Volume 96, Issue 1, Page 83-90, January/March 2025.Abstract The 2024 general election represented a remarkable comeback for the Liberal Democrats. Less than a decade on from the coalition and the 2015 election debacle, Sir Ed Davey's party reclaimed third‐party status in the House of Commons with seventy‐two MPs—the largest total for the Liberal Democrats or their Liberal Party predecessors since the ...

Housing Since 1945: The Impact of Policy Change and Ideology
The Political Quarterly, EarlyView.Abstract Housing policy in England has undergone significant reform on several occasions since 1945. Consensus approaches in the late 1940s and 50s to build large numbers of council houses and new private homes gave way to more ideologically driven policies in the 1970s and 80s.

Automated counting of fish in moving diver‐operated videos (DOV) for biodiversity assessments
Methods in Ecology and Evolution, EarlyView.Abstract Underwater video transects are crucial to assess marine biodiversity and biomass. Counting fish in these videos is labour‐ and time‐intensive and operator‐dependent. Automating this step would create non‐biased biodiversity data and decouple the data collection campaign from any field constraints.
