Quantifying spatial complexity in submerged aquatic vegetation landscapes using remote sensing: Lessons from simulated and real landscapes

Limnology and Oceanography, Volume 69, Issue 7, Page 1465-1480, July 2024.
Abstract The spatial organization of vegetation has been shown to be a strong indicator of ecological state in multiple ecosystems. In this study, we analyze the relationships between spatial complexity metrics in submerged aquatic vegetation (SAV) landscapes, and we explore the potential of satellite remote sensing to quantify these metrics in ...

UAS-GEOBIA Approach to Sapling Identification in Jack Pine Barrens after Fire [PDF]

Drones, 2018
Jack pine (pinus banksiana) forests are unique ecosystems controlled by wildfire. Understanding the traits of revegetation after wildfire is important for sustainable forest management, as these forests not only provide economic resources, but also are home to specialized species, like the Kirtland Warbler (Setophaga kirtlandii).

Combined optically stimulated luminescence and radiocarbon dating of aeolian dunes in Arctic Sweden

Permafrost and Periglacial Processes, Volume 35, Issue 2, Page 172-187, April/June 2024.
Abstract Multiple parabolic sand dune fields formed in Arctic Sweden after the last deglaciation, facilitated by an abundance of loose glaciofluvial sediment, limited vegetation cover and strong winds. Following initial stabilisation, these dunes underwent repeated reworking after fire events, as evidenced by the presence of buried soils, charcoal ...

Possibility of spatial estimation of soil erosion using Revised Universal Soil Loss Equation model and generalized additive model in post‐hard coal mining spoil heap

Land Degradation &Development, Volume 35, Issue 3, Page 923-935, 15 February 2024.
Abstract Revegetation and plant cover establishment on coal mining heap areas are effective methods for reducing runoff and soil erosion. They are essential components for reestablishing ecosystems in ecologically vulnerable areas. Our study area covered the Upper Silesia coal region.

Artificial Intelligence and Objective‐Function Methods Can Identify Bankfull River Channel Extents

Water Resources Research, Volume 60, Issue 1, January 2024.
Abstract Bankfull channel extents are of fundamental importance in fluvial geomorphology, to describe the geomorphic character of a river, and to provide a boundary for further processing of morphologic and hydraulic attributes. With ever‐increasing availability of high‐resolution spatial data (e.g., lidar, aerial photography), manual delineation of ...

Detecting Invasive Alien Plant Species Using Remote Sensing, Machine Learning and Deep Learning

Journal of Sensors, Volume 2024, Issue 1, 2024.
Invasive alien plants (IAPs) are nonnative species that pose significant threats to the environment by outcompeting native vegetation and disrupting ecosystem functions. Efforts to monitor and eradicate IAPs have been limited due to the challenges in accurately identifying these plants using traditional remote sensing (RS) methods.
