A dramatic 98% reduction in large-scale illegal logging has occurred in the core zones of Mexico's Monarch Butterfly Biosphere Reserve (MBBR) between 2012 and 2018, according to a new study. Researchers analyzed aerial ortho-photographs and satellite images, validated with fieldwork, to quantify forest cover loss—totaling 163.44 hectares—with climate-related factors (rain and wind) accounting for the majority (125.44 ha), while illegal logging (both large-scale and small-scale) contributed significantly less (38.0 ha and 12.14 ha, respectively). The findings suggest that despite ongoing threats, forest loss in the monarch's winter habitat is not the primary driver of their population decline since 2010, which has been far more severe than expected.

The German Wadden Sea is experiencing significant morphologic changes, with tidal flats steepening at an average rate of +7.9 mm/year while subtidal channels deepen at -20.0 mm/year, despite overall sediment accumulation and sea level rise. This counterintuitive trend suggests that the intertidal zone is expanding, even as mean depths in subtidal areas increase. Researchers analyzed digital elevation models from 1998 to 2016, revealing that most intertidal flats accumulate sediment faster than local sea level rise, while channels deepen. The study highlights the dynamic response of this UNESCO-listed ecosystem to changing environmental pressures.

A virtual reconstruction of the Presidio de San Pedro del Gallo, a historic military fortification along Mexico's Camino Real de Tierra Adentro, reveals key architectural and functional details lost to time. This study bridges historical documentation with modern digital techniques—such as architectural surveys—to reconstruct the presidio’s layout and daily activities, providing insights into its role in colonial defense. The findings highlight the potential for such reconstructions to support future heritage recognition, particularly under military or fortified patrimony categories. By combining historical analysis with virtual modeling, this work offers a method to preserve and interpret vanished fortifications, contributing to broader efforts in cultural preservation.

Ancient agricultural terraces and runoff harvesting installations in the Negev Highlands, Israel, offer unprecedented insights into environmental conditions during the middle Holocene. These structures, built between the 3rd–4th centuries CE and maintained for 6–7 centuries before abandonment after the 10th century, document over a millennium of land degradation and soil erosion. Using high-resolution 3-D data, researchers reconstructed the landscape's evolution from pre-anthropogenic intervention through centuries of cultivation to the present-day erosion phase. This study provides rare long-term measures of siltation and erosion rates in arid environments, enhancing understanding of environmental change mechanisms. Additionally, it offers valuable insights for soil conservation strategies, sustainable desert inhabitation, and protecting world-heritage installations, making it highly relevant amid global efforts to combat soil erosion.

After the Treaty of Corbeil in the 13th century, the fortified line along the southern French border underwent significant reconstruction and reinforcement. This study reveals that the seneschalcy of Carcassonne played a pivotal role in managing the logistics of building, maintaining, and equipping royal fortresses in the Corbières region. Additionally, private fortifications, particularly those belonging to the Archbishop of Narbonne, complemented the royal defenses. The research focuses on the most prominent fortifications near the treaty's border, providing insights into the strategic adjustments made during this period.
