Comparison of sustainable development research on the Yangtze River and Yellow River Basin

open access: yes资源科学
Both the development strategy of the Yangtze River Economic Belt and the ecological protection and high-quality development strategy of the Yellow River Basin are important basin strategies in China. However, the two watershed strategies were established in different times, under different natural environment, ecological status, economic development ...

Rise of the south: How Arab‐led maritime trade transformed China, 671–1371 CE

open access: yesAsia‐Pacific Economic History Review, Volume 65, Issue 1, Page 3-38, March 2025.
Abstract China's center of socioeconomic activities was in the North prior to the Tang dynasty but is in the South today. We demonstrate that Arab and Persian Muslim traders triggered that transition when they came to China in the late seventh century, by lifting maritime trade along the South Coast and re‐creating the South.

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

open access: yesBoreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Identifying the pre‐Odra river system with hydroacoustic and seismic reflection imagery offshore Rügen Island, southern Baltic Sea

open access: yesBoreas, EarlyView.
Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

open access: yesBoreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.
