    “…Invasive rats and goats played the ecological role of two endemic species, the cave goat and the giant dormouse, which inhabited the island for more than 5 million years and were rapidly extinct by humans. We used Landsat imagery to explore NDVI as a proxy of vegetation productivity over the years 1984–2021, orthophotos to assess changes in land and vegetation covers and historical plant inventories to study the dynamics in plant diversity. …”

    “…Specifically, small object detection implemented as an embedded system is gaining increasing attention for autonomous vehicles, drone reconnaissance, and microscopic imagery. In this paper, we present a light-weight small object detection model using two plug-in modules: (1) high-resolution processing module (HRPM ) and (2) sigmoid fusion module (SFM). …”

    “…To investigate whether these examples reflect an emerging broad‐scale problem, we used satellite imagery to quantify the change in mangrove habitat extent in 22 important shorebird areas in mainland China from 2000 to 2015.The extent of tidal flat across all sites declined significantly (p < 0.01, n = 22) while among sites with mangroves present, the extent of mangroves expanded significantly (p < 0.01, n = 14). …”

    “…While recent advances in machine learning and deep learning offer new promising ways to mine such rich datasets (e.g., satellite imagery, COVID statistics), spatial heterogeneity—an intrinsic characteristic embedded in spatial data—poses a major challenge as data distributions or generative processes often vary across space at different scales, with their spatial extents unknown. …”
