Six Decades of Forest Inventory Data Highlight Decline of Sugar Maple (Acer saccharum) Sapling Abundance in Eastern Canada

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Approximate (±10 km) geographic location of the 390 plots among the Atlantic Highlands, Mixedwood Plains, and Boreal Shield ecozones of eastern Canada. Six decades of forest inventory data showed a significant decline in the relative abundance of sugar maple (Acer saccharum) saplings between 1970 and 2022.

Key Landscape Factors Influencing Stream Physical Habitats Across the Brazilian Neotropical Savanna

Ecohydrology, Volume 18, Issue 3, April-May 2025.
ABSTRACT Improved management of small headwater streams in the Cerrado (Neotropical Savanna) biome in Brazil is necessary given the significant landscape transformations caused by anthropogenic activities in recent decades. Thus, we aimed to determine the relative influence of the leading natural landscape features and anthropogenic pressures on the ...

Occupancy of roe deer, water deer, and wild boar in wind farm‐integrated forest ecosystems: A case study in Korea

Ecosphere, Volume 16, Issue 5, May 2025.
Abstract Understanding the impact of anthropogenic structures on wildlife is essential for balancing ecosystem services. This study explored the impacts of anthropogenic disturbances, particularly wind farms, on South Korean Forest ecosystems using spatial occupancy models and camera trap survey data.

Integrating Geomorphology, Geology, and Geochemical Parameters to Understand the Preservation Status and Spatial Distribution of Archaeological Iron Objects Related to the 235 ce Roman–Germanic Harzhorn Conflict (Lower Saxony, Germany)

Geoarchaeology, Volume 40, Issue 3, May/June 2025.
ABSTRACT With more than 2000 excavated archaeological iron artifacts, the Roman–Germanic conflict site Harzhorn is among the best‐preserved battlefields from Classical Antiquity. The Harzhorn hogback, with its steep front face oriented to the north, is situated perpendicular to an important north–south passage west of the Harz Mountains in central ...

Geomorphological Evidence of Near‐Surface Ice at Candidate Landing Sites in Northern Amazonis Planitia, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract This work presents geomorphological analyses of an area at the boundary between Arcadia Planitia and northern Amazonis Planitia, situated in the northern mid‐latitudes of Mars. Recent studies have indicated the presence of substantial volumes of near‐surface excess ice in Arcadia Planitia, making this region a promising candidate for future ...

Learning without Exact Guidance: Updating Large-scale High-resolution Land Cover Maps from Low-resolution Historical Labels [PDF]

arXiv
Large-scale high-resolution (HR) land-cover mapping is a vital task to survey the Earth's surface and resolve many challenges facing humanity. However, it is still a non-trivial task hindered by complex ground details, various landforms, and the scarcity of accurate training labels over a wide-span geographic area.
