Land Degradation &Development, EarlyView.ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Age ratio in groups of a social ungulate affects epizoochorous dispersal and diaspore exchanges
Oikos, EarlyView.Animal‐mediated seed dispersal is a key process in plant population dynamics, species distribution and ecosystem functioning. As long‐distance dispersal agents, ungulates help to maintain native plant populations facing abiotic changes in their habitat and habitat fragmentation or habitat loss.

A Data-Driven Approach for GPS Trajectory Data Cleaning
, 2020 In this paper, we study the problem of GPS trajectory data cleaning, aiming to clean the noises in trajectory data. The noises can be generated due to many factors, such as GPS devices failure, sensor error, transmission error and storage error. Existing

Digital surveillance of animals and nature recovery
People and Nature, EarlyView.Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.
