Multiple high- and ultra-high-pressure orogenies in the Qinling Mountains: boundary conditions permitting their formation and exhumation

Ancient Building Complex in the Wudang Mountains — 2011 — WHEEA9FD5DDA6

A Triassic tectono-metamorphic event in the Qinling Mountains, characterized by high- and ultra-high-pressure conditions, was strongly influenced by syn- and post-tectonic magmatic activity. This event occurred due to the subduction of the Yangtze craton beneath the amalgamated Qinling-Erlangping-Sino-Korean continent, as indicated by thermobarometry and geochronology. The study also refutes the existence of a Late Palaeozoic Mianlüe ocean and its associated suture, based on new U/Pb zircon ages from mafic rocks. Research utilized petrological investigations, thermodynamic modeling, and geochronological techniques to constrain metamorphic conditions and timing across various tectono-metamorphic units in the Qinling orogen.

Muslim Reformist Networks in the City of Algiers, 1931–1940

Kasbah of Algiers — 2011 — WHE06C75C80C6

Muslim Reformist Networks in the City of Algiers, 1931–1940 reveals that the Association of Algerian Muslim ‘Ulamā (AUMA) underwent significant evolution during its early years. Initially focused on promoting an Arab and Islamic Algerian identity through mosques, schools, clubs, and charitable organizations, AUMA shifted its geographical presence from the Kasbah to the European area of Belcourt in the 1930s. This transition was accompanied by a shift in membership, moving away from the old Muslim establishment toward new social classes. Politically, AUMA's religious and cultural reformism gradually gave way to a more radical nationalist agenda. The study highlights the dynamic nature of this network, which constantly adapted while maintaining its influence on Algerian society.

Mycobacteria Isolated from Angkor Monument Sandstones Grow Chemolithoautotrophically by Oxidizing Elemental Sulfur

Angkor — 2011 — WHE7DCC1F7961

Researchers have discovered that Mycobacterium species isolated from the deteriorating sandstones of Angkor monuments in Cambodia exhibit remarkable metabolic versatility. These bacteria can grow both by oxidizing elemental sulfur (chemolithoautotrophically) and by consuming organic substances (chemoorganoheterotrophically). The study, involving five strains closely related to Mycobacterium cosmeticum and Mycobacterium pallens, focused on strain THI503, which demonstrated a significant decrease in medium pH during sulfur oxidation, confirming its role in energy metabolism. Fluorescence microscopy revealed that these bacteria adhere to and proliferate on sulfur particles, highlighting their adaptability in nutrient-limited sandstone environments. This dual metabolic capability suggests a potential mechanism for microbial contribution to stone deterioration.

National Policy Objectives and Local Management Results: The Economic, Social, and Environmental Performances of Shellfish-Farming Institutions in the Mont-Saint-Michel Bay (France)

Mont-Saint-Michel and its Bay — 2011 — WHE1352DBEB0A

Local management of shellfish farming in Mont-Saint-Michel Bay, France, has successfully prevented overexploitation but fails to align with national policy goals for economic equity and public revenue. The study reveals discrepancies between national objectives—aimed at sustainable marine resource use—and local outcomes, driven by institutional arrangements that overlook conflicting interests, information asymmetries, and unequal bargaining power. While mussel and oyster industries perform well environmentally, socioeconomic results such as rent distribution and job retention fall short of policy expectations. This suggests that the national regulatory framework did not adequately account for these factors, which, combined with opaque transferable use rights, shape local management processes.

Natural attenuation of priority and emerging contaminants during river bank filtration and artificial recharge

Paris, Banks of the Seine — 2011 — WHEFD95B61D9D

River bank filtration and artificial recharge significantly reduce the variety of organic contaminants, including drugs, polycyclic aromatic hydrocarbons, pesticides, oestrogenic hormones, and others, found in Seine river water downstream of Paris. However, while these processes decrease the presence of many pollutants, they can inadvertently increase nonylphenols due to the anaerobic degradation of their precursors. Despite treatment, traces of aspirin, nonylphenols, and stimulants were occasionally detected in finished drinking water above 0.1 μg/L. The study monitored over 80 contaminants across five sampling campaigns at various stages of water treatment, including river water, bank filtration, artificial recharge, and post-treatment mixtures.

Natural history of the common tree snake, Dendrelaphis punctulatus (Serpentes : Colubridae), in the wet–dry tropics of north Queensland

Wet Tropics of Queensland — 2011 — WHED9EDE980AA

A seven-year field study of the common tree snake, Dendrelaphis punctulatus, in north Queensland's Wet Tropics revealed strong seasonal reproduction tied to the dry-to-wet season transition, with clutch size linked to maternal body size. Unlike previous research relying on museum specimens, this study provided detailed observations of a melanotic population, showing diurnal activity peaking during reproduction and a diet primarily consisting of frogs, lizards, and locusts. Females were significantly larger than males in all measured traits, including mass and head size.

Natural reforestation of abandoned eucalypt plantations in the Brasilia National Forest

Brasilia — 2011 — WHE8EC59EF614

A long-term equilibrium between eucalypt and native Cerrado species is predicted to emerge after 50 years of natural reforestation in abandoned eucalypt plantations within the Brasilia National Forest, with eucalypts dominating. Field observations indicate that eucalypt species pose no significant threat to adjacent undisturbed Cerrado areas, likely due to the inhibitory effects of native grasses on the dispersal and germination of eucalypt seeds. This conclusion was reached through a discrete event simulation model based on census data from both plantation and native Cerrado areas.

Nature's Eden? The production and effects of 'Pristine' nature in the Galápagos Islands.

Galápagos Islands — 2011 — WHE33A13E3084

The Galápagos Islands, renowned as an 'evolutionary Eden' and a symbol of pristine nature, are not inherently natural but are socially constructed concepts that shape tourism and infrastructure development. This study reveals how the perception of pristine nature in the Galápagos has led to uneven social outcomes and environmental impacts, despite its UNESCO World Heritage status. By analyzing the material and political effects of these understandings, researchers demonstrate that the crisis of overdevelopment stems from the idealization of untouched landscapes rather than ecological realities. The paper argues for a rethinking of the islands' nature, emphasizing the need to address the complexity of social-environmental relations to mitigate ongoing challenges.

Nature’s Eden? The Production and Effects of ‘Pristine’ Nature in the Galápagos Islands

Galápagos Islands — 2011 — WHEC58F739ECB

The Galápagos Islands, renowned as an 'evolutionary Eden,' are often perceived as a bastion of pristine nature. However, research reveals that the concept of 'pristine' nature is not innate but socially constructed, reflecting specific understandings of island space. This study demonstrates how such perceptions shape tourism and infrastructure investments, leading to social inequalities and environmental harm. It argues for a reevaluation of the islands' nature, emphasizing the complexity of social-environmental relations. Measures addressing the current crisis would benefit from this critical perspective.

Nearshore circulation in a tropical fringing reef system

Ningaloo Coast — 2011 — WHEDBD333A71C

Wave breaking is the dominant force driving circulation in Ningaloo Reef's fringing system, overwhelming tidal and wind influences. A six-week field study revealed that wave-driven currents shape cross-reef and alongshore flows, with flushing times ranging from hours to days depending on wave conditions. Tides modulate high-frequency current variability but play a secondary role compared to waves. The findings suggest Ningaloo Reef's circulation is highly sensitive to sea level rise, with potential impacts on its ecological dynamics.

Negligible soil erosion in a burned mountain watershed, Canadian Rockies: field and modelling investigations considering the role of duff

Canadian Rocky Mountain Parks — 2011 — WHE51E2627618

A high-intensity crown fire in Kootenay National Park, British Columbia, resulted in negligible soil erosion (10–1 to 100 t ha⁻¹) in the immediate post-wildfire years, contrary to documented trends. The study attributes this to remnant duff—a layer of decomposed organic material—that persisted after the fire. Duff acts as a hydrological buffer, absorbing rainfall and preventing overland flow, while also physically protecting soil from erosion. Using the Green–Ampt model, researchers demonstrated that duff's high porosity and water storage capacity effectively mitigate erosional impacts during rainstorms. This finding challenges assumptions about post-wildfire erosion dynamics in subalpine forests and underscores the role of organic layers in stabilizing watersheds.

The study documented 400+ plant taxa across four villages in Transylvania (2007–2010), identifying 9 preparation methods still used for treating diseases like digestive disorders and respiratory ailments. Interviews with 130 locals and 80 field days yielded 6,000 photos, audio recordings, and detailed ethnobotanical data, bridging medieval monastic texts (e.g., Pannonhalma Abbey) with contemporary folk medicine. Findings underscore the resilience of indigenous pharmacological knowledge, offering valuable insights for medical and pharmacological research.

Nesting of the Fulvous-breasted Flatbill (Rhynchocyclus fulvipectus) in Southeastern Perú

Manú National Park — 2011 — WHE11790E08D9

Research on the Fulvous-breasted Flatbill (Rhynchocyclus fulvipectus) in southeastern Peru's Manu National Park buffer zone reveals unique nesting behaviors, including a two-egg clutch size and pear-shaped nests, consistent with prior reports. The study, conducted from August to December 2009, used data loggers to monitor seven nests, documenting incubation patterns and provisioning behavior. Key findings include a 24-day incubation period, during which only one parent (likely the female) incubated the eggs with an average attentiveness of 64%, decreasing over time—a pattern contrasting with previous neotropical passerine studies. Nestlings remained in the nest for at least 29 days and exhibited lower body temperatures (37°C) than adults post-feathering, suggesting prolonged dependency. The study also confirmed that Rhynchocyclus nests are exclusively found along creeks or rivers, hinting at longer incubation and nestling periods potentially common in tropical mountain regions.

This finding contributes critical data for botanists and environmentalists working in the region.

New finds of middle and late jurassic radiolarians in the siliceous-clayey and clastic rocks of the Nadan’khada-Bikin terrane (Jurassic accretionary wedge, western Sikhote Alin) and their geological significance

Central Sikhote-Alin — 2011 — WHEC7A2BECEB5

Researchers have uncovered radiolarian fossils dating back to the late Bajocian and early to middle Bathonian periods (Middle Jurassic) as well as terminal late Tithonian (Late Jurassic) in the Nadan’khada-Bikin terrane of the Sikhote-Alin region, Russia. These findings, derived from lithostratigraphic analysis of paleo-oceanic sediments, provide critical insights into the geological history of this accretionary wedge. By integrating these discoveries with existing data, scientists have identified three distinct stages in the formation of the Bikin segment: terminal Middle Jurassic, late Tithonian, and Berriasian. This process spanned approximately 25 million years, offering a deeper understanding of tectonic evolution during the Mesozoic era.

New geological and geochemical data on the granitoids of the Uspensky massif in Southern Primorye

Central Sikhote-Alin — 2011 — WHE5F24E3C385

Research on the Uspensky granitoid massif in Southern Primorye reveals two distinct associations of granitoids, formed at 103.3 ± 2.4 Ma and 99 ± 2 Ma respectively, with unique geological and geochemical characteristics. The early association consists of garnet-bearing biotite and two-mica granite-leucogranites, while the late association includes biotite (±amphibole) granodiorites, melanogranites, and granites. These granitoids exhibit moderate potassic alkalinity and elevated alumina contents but differ in their proportions of alumina, calcium, and alkalis. The study also highlights distinct trace-element compositions, with garnet-bearing granite-leucogranites showing high Rb, Th, and U contents and low Sr, Ba, Hf, and Zr contents, while melanogranites display higher Sr and Ba contents. The research suggests that both associations correspond to S-type granitoids formed by partial melting of crustal protoliths, indicating the generation of S-granites at different stages in the formation of the Central Sikhote Alin plutonic belt within a transform continental margin setting.
