Rapid response of a grassland ecosystem to an experimental manipulation of a keystone rodent and domestic livestock
Archaeological Zone of Paquimé, Casas Grandes — 2010 — WHE2EE37D9A7A
A study at the UNESCO World Heritage Site, Archaeological Zone of Paquimé, Casas Grandes, reveals that domestic cattle and prairie dogs—keystone burrowing rodents—exert synergistic impacts on grassland ecosystems. The research found nearly twofold increases in prairie dog abundance when cattle were present, leading to significantly lower vegetation height where both species co-occurred compared to plots without them. This interaction also influenced the abundance and composition of other grassland animals, including grasshoppers and banner-tailed kangaroo rats. Conducted using a long-term 2 x 2 factorial experiment in Mexico's Janos-Casas Grandes region, the study highlights the distinctive and combined roles of these herbivorous mammals in shaping grassland structure and function.
Rare earth elements, Sr, Ba, Fe, and major cation concentrations in some living foraminiferal tests collected from Iriomote Island, Japan: An exploration for trace element behavior during biogenic calcium carbonate formation
Amami-Oshima Island, Tokunoshima Island, Northern part of Okinawa Island, and Iriomote Island — 2010 — WHE09C508835B
Research on living foraminiferal tests from Iriomote Island, Japan, reveals that rare earth elements (REEs), strontium (Sr), and magnesium (Mg) incorporate into biogenic calcium carbonate following patterns consistent with crystal structure and ionic radius control. The study found that the sample/seawater concentration ratios of these elements align with theoretical models predicting cation incorporation based on size compatibility. However, iron (Fe) and barium (Ba) exhibited higher-than-expected ratios, suggesting the presence of insoluble precipitates like Fe-hydroxides and barite. Notably, REE concentrations correlated with Fe, implying coprecipitation during seawater exposure or intracellular digestion before CaCO3 crystallization. This study provides insights into trace element behavior in biogenic calcium carbonate formation, offering a deeper understanding of geochemical processes in marine environments.
Reactions against Historicism of German Bauhaus and the Reaction against “Passeism” of Italian Futurism
Bauhaus and its Sites in Weimar, Dessau and Bernau — 2010 — WHE5F192A500D
Bauhaus, a pioneering school of art and architecture founded in Weimar by Walter Gropius, emerged as a radical reaction against historicism and contemporary 'dead style' in architecture. This movement, marked by its modern, functional, and economical aesthetic, sought to reform both art education and society. The study analyzes the ideological roots of Bauhaus's opposition to historicism, emphasizing its philosophical underpinnings and aesthetic innovations. It also compares this reaction with Italian Futurism’s strong stance against 'Passeism,' providing a nuanced understanding of how these movements challenged established norms in early 20th-century Europe.
Reclaiming Catherine of Siena: Literacy, Literature, and the Signs of Others by Jane Tylus
Val d'Orcia — 2010 — WHEC008A1F78B
Jane Tylus' work 'Reclaiming Catherine of Siena: Literacy, Literature, and the Signs of Others' challenges historical skepticism surrounding Catherine of Siena's literacy, establishing her as a pioneering Italian writer. The study employs a meticulous analysis of Catherine's letters, dictated works from Pisa, and her later writing in Rome, alongside hagiographic texts by Raymond of Capua and Tommaso Caffarini. Tylus argues that Catherine learned to write during her time in the Val d'Orcia in 1377, using Tuscan vernacular deliberately, thereby positioning her alongside Dante and Petrarch in the development of Italian literature. The research also examines the preservation and presentation of her literary legacy, including Girolamo Gigli's 18th-century defense and Aldus Manutius' 16th-century edition. Through linguistic analysis, Tylus reconstructs Catherine's self-understanding as both a speaker and writer, offering new insights into her authorship and the cultural significance of her work.
Reconsidering the Size and Structure of Casas Grandes, Chihuahua, Mexico
Archaeological Zone of Paquimé, Casas Grandes — 2010 — WHEBA86630C03
A reexamination of the UNESCO World Heritage Site, Archaeological Zone of Paquimé (Casas Grandes), challenges long-held assumptions about its size and structure. Contrary to previous estimates suggesting a vast U-shaped pueblo with up to 2,300 rooms and nearly 5,000 residents, this study proposes a more compact central linear room block, flanked by smaller, scattered one-story units. The original room count is revised downward by approximately 50%, significantly altering models of internal and regional organization for Casas Grandes. This conservative reanalysis relies on a meticulous reassessment of architectural configurations, emphasizing the need to critically evaluate foundational interpretations in archaeological research.
Reconstitution de l'entrée préhistorique de la grotte Chauvet-Pont d'Arc (Ardèche, France) : les apports de l'analyse géomorphologique et de la modélisation 3D
Decorated Cave of Pont d’Arc, known as Grotte Chauvet-Pont d’Arc, Ardèche — 2010 — WHE540132AB5F
A groundbreaking reconstruction of the prehistoric entrance to Chauvet Cave reveals critical insights into its sealing process. Using geomorphological analysis and 3D modeling with lasergrammetry data, researchers determined that the cave's exceptional preservation stems from a limestone ledge collapse that blocked access around 23,000 to 11,500 years ago. The study identified the former extent of the cave, detailed the size and features of its prehistoric porch, and clarified how ceiling pendants influenced rockfall distribution within the cave. While dating remains imprecise due to limited speleothem data, this method offers a new approach to understanding cave sealing mechanisms and could refine age estimates with further research.
Reconstruction of the New Station Square in Berne, Switzerland
Old City of Berne — 2010 — WHE332909C459
The reconstruction of the New Station Square in Bern, Switzerland, not only addressed structural safety and durability concerns but also transformed the area into an appealing entrance adjacent to the UNESCO World Heritage-listed Old City. The 2007 project, covering 40,000 m², included dismantling parts of concrete slabs and columns while adding new elements and strengthening existing ones. A key innovation was the use of post-installed inclined bonded bars to reinforce the ceiling against punching shear, a method that enhanced structural integrity. Additionally, the reconstruction optimized local transportation stops, an underground shopping center, and pedestrian flow, creating a more functional and aesthetically pleasing urban space.
Records of Great White Sharks (Carcharodon carcharias) in New Caledonian Waters
Lagoons of New Caledonia: Reef Diversity and Associated Ecosystems — 2010 — WHE1DD3A2B71D
Great white sharks (Carcharodon carcharias) are confirmed to inhabit New Caledonian waters, with 34 individual sharks documented across 30 observation events between 1943 and 2009. These observations, including sightings, captures, and forensic examinations, were predominantly concentrated in the southern lagoon or along the barrier reef, with a seasonal peak from July to March, particularly in September and November. Nearly all sharks were solitary, and some were recorded feeding on whale carcasses or tagged in New Zealand's Chatham Islands. The study highlights the presence of this apex predator in New Caledonia, offering insights into its distribution and behavior, which may coincide with large cetacean occurrences.
Recruitment and Succession of Riparian Vegetation in Alluvial River Regulated by Upstream Dams - Focused on the Nakdong River Downstream Andong and Imha Dams -
Historic Villages of Korea: Hahoe and Yangdong — 2010 — WHEF7F1C1B6EF
Upstream dams on the Nakdong River have significantly accelerated riparian vegetation recruitment and succession, transforming once-bare sandbars into diverse habitats. Research shows that post-dam riverbed degradation and reduced bed shear stress due to decreased flood discharge promoted vegetation establishment, increasing vegetated bar ratios from 7% in 1971 to 74% by 2005. Detailed analysis of subreaches revealed a clear succession from pioneering stages (e.g., Reed spp.) to shrub and tree stages (e.g., willows), while some historically bare sandbars near Hahoe Village showed recent vegetation encroachment, threatening conservation efforts. The study confirms that dam-induced hydrological changes can create unique backmarsh habitats, potentially enhancing biodiversity compared to natural sandy rivers.
Redescription, systematic status and molecular characterisation of Multicaecum heterotis Petter, Vassiliadès et Marchand, 1979 (Nematoda: Heterocheilidae), an intestinal parasite of Heterotis niloticus (Osteichthyes: Arapaimidae) in Africa
Niokolo-Koba National Park — 2010 — WHE429F2BF591
A key discovery in the study of intestinal parasites of the African bonytongue (Heterotis niloticus) has been made, confirming that Multicaecum heterotis belongs to the genus Multicaecum rather than Brevimulticaecum. This was achieved through detailed morphological examination using light microscopy and scanning electron microscopy, which revealed previously unreported features such as dentigerous ridges on the inner edges of the lips. Additionally, this is the first species of the genus Multicaecum to be sequenced, providing partial sequences of the 18S rDNA and ITS2 regions for molecular characterization. The study also provides a key to distinguish between Brevimulticaecum and Multicaecum species, contributing significantly to our understanding of nematode taxonomy and systematics.

Relationship between soil moisture and vegetation in the Kairouan plain region of Tunisia using low spatial resolution satellite data
Kairouan — 2010 — WHE23468F9A21
A strong correlation exists between soil moisture and vegetation dynamics in the Kairouan plain, Tunisia. Researchers developed a semiempirical model using low-resolution satellite data (1991–2006) to predict normalized difference vegetation index (NDVI) values based on soil moisture profiles from prior months during the rainy season (October–May). Validated against rainfall events and Global Soil Wetness Project data, this approach offers a simple yet effective tool for modeling vegetation in semiarid regions. The study highlights how satellite-derived moisture data can serve as a reliable indicator of vegetation development, advancing our understanding of water-vegetation interactions in arid ecosystems.
Reproductive Synchrony inAcroporaAssemblages on Reefs of New Caledonia
Lagoons of New Caledonia: Reef Diversity and Associated Ecosystems — 2010 — WHEC2E8F14013
Research on the Lagoons of New Caledonia, a UNESCO World Heritage Site and home to the world's second largest barrier reef, reveals that Acropora coral reproduction is highly synchronized across eight sites spanning 200 km. The study found that 80% of 1,055 Acropora colonies contained mature oocytes, with 34 out of 37 species exhibiting at least one mature colony. This suggests a multispecies spawning event following the full moon in November, aligning with the mass spawning period on Australia's Great Barrier Reef. The high synchrony implies that even brief disruptions to fertilization and early development, such as liquid waste discharge from ore processing, could significantly impact these globally valued reefs.
