Datations 36Cl de la fermeture de la grotte Chauvet, implications géomorphologiques et archéologiques

Decorated Cave of Pont d’Arc, known as Grotte Chauvet-Pont d’Arc, Ardèche — 2012 — WHE45FEE4143C

A groundbreaking study reveals that the Chauvet Cave, renowned for its prehistoric art and archaeological significance, was sealed off approximately 22,000 years ago due to a series of sudden rockfalls. This finding challenges traditional chronological frameworks by providing an absolute timeline for the cave's closure, extending its human occupation back to 34,000 years. The research utilized a combination of high-resolution topographic surveys (terrestrial LiDAR) and cosmogenic dating (36Cl) to analyze rockfall scars and deposits, reconstructing the cave's paleo entrance. This method offers a precise geomorphological and archaeological context, shedding new light on the cave's history and its implications for understanding human behavior during the Upper Paleolithic period.

Dating the Irrigation System of the Samarkand Oasis: A Geoarchaeological Study

Samarkand – Crossroad of Cultures — 2012 — WHE32F1156A53

A groundbreaking geoarchaeological study provides definitive evidence that the irrigation system of Samarkand's oasis, a pivotal center in ancient Central Asia, was primarily developed in the 2nd century AD. By combining radiocarbon dating of sediments and charcoals from archaeological sites with numerical modeling of flood events, researchers established the existence and timeline of two key canals, Dargom and Yanghiaryk, on the southern flank of the Middle Zeravshan Valley. The study also ruled out natural floods as the cause for damage observed at a 2nd-century AD site (SAM-174), reinforcing the artificial origin of these canals. This challenges earlier hypotheses and offers precise dating, advancing our understanding of Samarkand's historical development.

De middeleeuwse bedelordearchitectuur in Nederland

Assisi, the Basilica of San Francesco and Other Franciscan Sites — 2012 — WHEE27D596D72

Mendicant architecture in the Netherlands, from the 13th to the early 16th century, exhibited distinct characteristics that set it apart from parish and collegiate churches. The study reveals a preference for simplicity, with buildings lacking towers, transepts, or radiating chapels, and using economical materials like stone, brick, and wood. Despite this 'poverty' in structural elements, the interiors were adorned with rich furnishings, including tombs, altars with retables, stained glass windows, and paintings, often gifted by burghers and confraternities. The research, based on a two-year fellowship at Leiden University, analyzed 57 friaries across 43 Dutch towns, using dendrochronological studies and archaeological excavations to reconstruct the growth process of these churches. It identified two main building waves: an early phase with aisled basilicas featuring polygonal choirs and ribbed vaults, and a later 15th-century wave dominated by hall-churches with wooden barrel vaults. The study also highlighted the functional division between the choir for liturgical offices and the preaching area for public use, including burials and civil meetings.

De Waddenzee, een gigantisch wereldnatuurerfgoedpark

Wadden Sea — 2012 — WHEBF3DA58900

The Wadden Sea, a UNESCO World Heritage Site since 2009, presents a unique challenge in balancing nature preservation with tourism and economic activities. While Germany and Denmark embrace the entire Wadden Sea as a national park, fostering tourism through accessible mudflats and tidal marshes, the Netherlands has historically been more reserved due to past land reclamation ambitions. However, recent initiatives like the 'Waddenfonds' are shifting this narrative by funding scientific research, nature compensation projects, and infrastructure development such as mudflat centers and cycling routes along the dikes. These efforts aim to create a multifunctional dike that enhances visitor experiences while protecting the delicate ecosystem, marking a significant shift in Dutch policy towards embracing the Wadden Sea's natural heritage.

Declines amongst breeding Eider Somateria mollissima numbers in the Baltic/Wadden Sea flyway

Wadden Sea — 2012 — WHE8FB2D3DBCB

Breeding Eider populations in the Baltic/Wadden Sea flyway have experienced a dramatic 48% decline between 2000 and 2009, following stability from 1991 to 2000. The majority of these declines occurred in Finland and Sweden, where breeding pairs halved over the same period. While wintering numbers increased in the Baltic Sea during this time, they decreased in the Wadden Sea. Analysis of Danish hunting bag data revealed a shift in population structure, with adult female proportions dropping from 45% to 25%, while first-winter birds fell from 70% to 30%. These trends suggest continued population decline unless factors reducing adult female survival are addressed. The study highlights the need for improved flyway-level monitoring and management to mitigate these declines.

Delineating the Rattlesnake Springs, New Mexico Watershed using Near-Surface Geophysical Techniques

Carlsbad Caverns National Park — 2012 — WHEC799636E7B

Groundwater flow into Rattlesnake Springs, the vital domestic water source for Carlsbad Caverns National Park, is influenced by fine-grained clays acting as a barrier and north-south/west-northwest fractures in gypsum bedrock serving as conduits. These findings, derived from ground conductivity, DC resistivity, and precision gravity surveys, confirm geological hypotheses about the springs' location and suggest regional tectonism shaped the fracture system. The study provides critical insights into the watershed's structure, aiding water resource management.

Demography and population trends of Whooping Cranes

Wood Buffalo National Park — 2012 — WHE7A94672C49

A comprehensive analysis of Whooping Crane (Grus americana) demography reveals that the Aransas National Wildlife Refuge/Wood Buffalo National Park population is unlikely to reach the target down-listing size of 1000 individuals by 2035, potentially delaying this milestone until the mid-2060s. Researchers estimated age-specific survival and natality rates using data from 12 cohorts of banded cranes, parameterizing an age-structured density-dependent model to project population sizes under different wintering ground carrying capacity scenarios. Findings indicate that even if all suitable habitat within a 100-km radius of their current range is occupied, the population may only reach approximately 700 individuals by 2035. The study highlights the potential for decreased growth rates due to territorial behavior and faithfulness to migratory routes, suggesting long-term challenges for recovery efforts.

Dendrochronological reconstruction of spruce budworm (Choristoneura fumiferana) outbreaks in southern Quebec for the last 400 years1This article is one of a selection of papers from the 7th International Conference on Disturbance Dynamics in Boreal Forests.

Historic District of Old Québec — 2012 — WHE82438E4B6F

A dendrochronological study reveals that spruce budworm (Choristoneura fumiferana) outbreaks in southern Quebec have been frequent, severe, and synchronized for the past 400 years, with no evidence of recent dynamics exceeding historical norms. The research used tree-ring data from old buildings and old-growth stands to reconstruct outbreak history, identifying nine confirmed outbreaks and three uncertain ones. While outbreaks became more frequent (every ~30 years) in the 20th century compared to 1660–1850 (~50 years), similar or even higher frequency may have occurred before 1660 (~28 years). This challenges previous assumptions based on living trees, suggesting earlier outbreaks were more frequent and synchronized than previously thought.

Depositional processes of reworked tephra from the Late Pleistocene Youngest Toba Tuff deposits in the Lenggong Valley, Malaysia

Archaeological Heritage of the Lenggong Valley — 2012 — WHE3A5BE62BE9

Reworked tephra from the Late Pleistocene Youngest Toba Tuff (YTT) deposits in Malaysia's Lenggong Valley exhibit complex sedimentological characteristics that challenge traditional distinctions between primary and reworked tephra. Analysis of particle-size distributions, magnetic susceptibility, and mineralogical associations revealed that reworked tephra can mimic primary deposits, highlighting the limitations of particle size alone for differentiation. The study identified three depositional facies—flood flow, mudflow, and slumping—suggesting rapid accumulation over days to months. While Kampung Luat 3 emerged as a potential site for paleoenvironmental reconstructions due to distinct ash phases, the study cautions against overreliance on reworked tephra records, given uncertainties about time lags and site-specific modifications.

Des comtes de Carcassonne aux vicomtes de Minerve

Historic Fortified City of Carcassonne — 2012 — WHEE4AF01946F

The transition from the Counts of Carcassonne to the Viscounts of Minerve, documented in this study, reveals significant political and territorial upheaval in Languedoc following the intervention of the counts of Barcelona. The research suggests that the first Viscounts of Minerve may have been direct descendants of Count William of Carcassonne, inheriting a network of castles and revenues previously held by the county. This shift marked a pivotal moment in the region's history, as the allodium of Minervois became a fief under the Trencavel, illustrating the broader impact of Barcelona's influence on Languedoc's feudal structure. The study employs historical analysis to trace these changes, providing insights into the complex inheritance patterns and power dynamics of the period.
