Regional analysis of spatiotemporal trends in Colorado potato beetle abundance

open access: yesPest Management Science, EarlyView.
Leveraging a large data set on Colorado potato beetles in Wisconsin, we examine spatial and temporal abundance trends. Spatiotemporal statistical models substantially improve fit and show that climate and management factors are positively associated with abundance levels.

Historical remote sensing highlights long‐term persistence of Emperor Penguin (Aptenodytes forsteri) colonies

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Remote sensing can reveal population dynamics of Antarctic penguin colonies. In this study, we analyze emperor penguin (Aptenodytes forsteri) guano stains in remote sensing imagery and discover colony presence predating known records for 18 colonies across Antarctica.

Time‐series digital camera photos combined with machine learning algorithms can realize accurate observation of flowering phenology

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Intelligent approaches are required to extract valuable phenological information from time‐series digital camera photos. In this research, we employed YOLO‐based object detection and semantic segmentation models to identify flowers and flower pixels, acquire flower count and flower cover data, and extract phenophases such as first, peak, and end ...

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).
