Landslide Volume, Mobility, and Recurrence on Grand Mesa, Colorado: Insights from a 781-Event Inventory

This study utilizes a comprehensive inventory of 781 landslides on Grand Mesa, Colorado, to reveal that while high-volume megaslides occur roughly once every millennium, smaller but highly mobile events are frequent, with the Green River-Uinta Formation disproportionately driving landslide activity due to its unique lithology and stratigraphic position.

From Water to Fish: Microplastic Exposure and Ecological Risk in a Tropical Freshwater Fishery Lake in the Philippines

This study reveals that Lake Sampaloc in the Philippines suffers from severe microplastic pollution, with surface waters showing very high contamination levels and farmed fish accumulating significantly higher microplastic loads than wild counterparts, primarily consisting of polyethylene and polypropylene fibers that exhibit size-dependent accumulation patterns.

Monitoring sika deer population dynamics under culling on Nakanoshima island, Japan, using thermal infrared UAV survey

This study demonstrates that six-year thermal infrared UAV surveys provide a highly reliable, cost-efficient, and effective method for monitoring long-term sika deer population dynamics and detecting culling-induced declines on Nakanoshima Island, Japan, outperforming traditional ground-based methods in effort while correlating strongly with harvest-based estimates.

Contents and Site-Specific Variations of Potentially Toxic Elements (PTEs) in the Feces of the Laughing Dove Spilopelia senegalensis as an Indicator of Environmental Contamination in an Urban Area (a case study of Yerevan, Armenia)

This pilot study demonstrates that the feces of the laughing dove (*Spilopelia senegalensis*) serve as an effective non-invasive biomonitoring tool for tracking urban environmental contamination in Yerevan, Armenia, by revealing significantly elevated levels of anthropogenic toxic elements like lead and arsenic in industrial peripheral zones compared to the city center.

Effects Climate Variability on Household Income Stability Among Smallholder Farmers in Rutsiro District of Western Province, Rwanda

This mixed-method study conducted in Rwanda's Rutsiro District (2024–2026) reveals that climate variability, particularly rainfall fluctuations and droughts, significantly undermines household income stability for 297 smallholder farmers, explaining 67.5% of income instability and necessitating urgent interventions in climate-smart agriculture and irrigation.

Using portable x-ray fluorescence with biological collections to broaden ecotoxicology research

This paper outlines and demonstrates a strategy for expanding ecotoxicology research by pairing biological collections with portable x-ray fluorescence (pXRF) analyzers to enable rapid, non-destructive, and large-scale assessment of lead contamination in bird specimens across diverse spatial, temporal, and taxonomic scales.

Phosphorus Allocation and Stoichiometric Homeostasis in Suaeda salsa Under Sediment Burial and Nitrogen Input in the Yellow River Delta

This study demonstrates that the pioneer species *Suaeda salsa* in the Yellow River Delta maintains strong phosphorus homeostasis across its organs despite sediment burial and nitrogen input, while adapting to these environmental disturbances by adjusting nitrogen/phosphorus stoichiometry and root phosphorus accumulation strategies.

Carbon storage efficiency and permeability decay during microbubble and conventional carbon dioxide injection in high-permeability sandstone

While microbubble CO₂ injection can enhance carbon storage efficiency in high-permeability sandstone at low flow rates by temporarily blocking dominant flow channels, it ultimately leads to greater permeability decay and injectivity risks compared to conventional injection, particularly at higher flow rates due to fines mobilization and cumulative formation damage.

Long-lead predictability of Indian summer monsoon rainfall from the new upgraded version of the monsoon mission coupled forecast system (MMCFSv2)

The study demonstrates that the upgraded Monsoon Mission Climate Forecast System version 2 (MMCFSv2) achieves its highest long-lead predictability for Indian Summer Monsoon rainfall when initialized in April, significantly improving the simulation of rainfall phase, amplitude, and extreme years compared to other initialization times.
