Summary: Litter pollution is a global environmental problem predominantly studied in relation to plastics in the marine environment. However, empirical knowledge about litter distribution and ecological impacts in terrestrial environments is limited. This study in central Norway found that land cover type affects the occurrence and abundance of litter, with high human activity areas having the most litter. Plastic is the most common litter material type, but its occurrence is related to land cover type. This knowledge can inform litter management in terrestrial landscapes.

Summary: This study evaluated the land cover dynamics in western Chilean Patagonia and found that there was a loss of approximately 32,600 ha of old-growth forest and a recovery of approximately 69,000 ha of second-growth forest following the fires. However, around 61% of the area could potentially remain as intact forest landscape after the fires. This study provides the first evidence of the landscape state in western Patagonia after more than six decades since the large-scale fires.

Summary: Cropland abandonment is a global concern that affects both socio-economic and ecological aspects. This study developed different spatial metrics to explore the patterns and causes of cropland abandonment in a highly water-deficient agricultural landscape in Central Iran. Using Landsat images, annual cropland layers were generated from 1982 to 2022, and areas with more than 5 consecutive years of fallow were classified as abandoned croplands. The results showed that cropland abandonment had a spatially and temporally uneven distribution, with most abandonment occurring on the periphery of active croplands. The spatial configuration of abandonment sheds light on the process and driving forces of cropland abandonment at different scales.

Summary: The main goal of landscape ecology is to understand the impact of habitat transformation on biodiversity. However, the discipline faces challenges due to the context dependency of observed spatial and temporal trends. This study discusses recent evidence suggesting that factors and processes at macroecological scales, such as historical disturbance rates, distance to geographic range edges, and climatic suitability, modulate populations' and species' responses to habitat change at the landscape scale.

Summary: Missing data is a common issue in remote sensing, and data reconstruction through multiple satellite data sources is an effective way to solve this problem. This study aimed to develop and evaluate two image reconstruction strategies based on measured SPM concentration data with Sentinel-2 and Sentinel-3. The results showed that ESTARFM performed better than FSDAF in fusion image generation, especially in the red band. A single-band linear and non-linear regression model based on Sentinel-2 and Sentinel-3 was constructed, and the red band model was found to perform well and have a wide range of applications. By comparing two data reconstruction strategies, it was found that the fused SPM concentration map is more effective and stable when applied to multiple fused images. These findings provide important scientific reference for future inversion research on other water quality parameters and support the scientific management of Ebinur Lake's ecology and environment.
