WHE247888C414
Between 1995 and 2011, glaciers in the Glacier Bay region of Alaska and British Columbia lost mass at a significantly lower rate compared to their long-term average since the Little Ice Age. The study estimated an average mass loss of 3.93 ± 0.89 gigatons per year (0.6 ± 0.1 meters water equivalent annually) for this period, down from 17.8 gigatons per year post-LIA. Researchers used airborne laser altimetry data to track elevation changes across four time intervals, extrapolating center-line profiles to entire glaciers and averaging results regionally using three methods. This approach also revealed a lower bias in mass loss estimates compared to previous digital elevation model difference techniques. The findings align with gravitational measurements from the GRACE satellite for 2003–10, reinforcing their accuracy.
Vredefort Dome

Preliminary results showed promising detection, validating the potential of small-scale radio telescopes in large-scale astronomical studies.
Timbuktu
—
2013 —
WHE61D8509063
Groundwater recharge at Timbuktu, Mali, occurs at a minimal rate of 4 mm annually, constituting just 1–2% of the region's average precipitation. This limited recharge is primarily driven by runoff and channeling in depressions between dunes, known as 'mares,' which retain water for extended periods post-rainy season. The study, using chloride budgets from well clusters and soil profiles, also revealed that occasional high nitrate concentrations in soil and groundwater are likely due to nitrogen-fixation by cyano-bacteria thriving on the moist soil surfaces of these mares. This finding underscores the region's highly variable precipitation patterns and highlights a sustainable water demand by local settlements relative to the assessed recharge rates.

Yellowstone National Park
—
2013 —
WHE2656ECD06D
A groundbreaking physical model has successfully replicated the eruption intervals of Old Faithful geyser, Yellowstone National Park, from 2000 to 2011. The model hinges on convective boiling within the geyser's conduit and aligns with existing time-temperature-depth data. It identifies a preplay phase—critical for determining main eruption intervals—that follows a Rayleigh probability density function, peaking at nine minutes. Assuming minimal temperature gradients due to convection, the model assigns uniform heat content to individual convection cells and uses observed bottom heating (110 °C) and recharge temperatures (80 °C), with a total conduit volume of 23 m³. The composite model effectively reproduces Old Faithful's bimodal eruption pattern, where long durations precede prolonged intervals and vice versa. While the cause of short eruption durations remains unresolved, this study provides a robust framework for understanding geyser dynamics.
Cerrado Protected Areas: Chapada dos Veadeiros and Emas National Parks
—
2013 —
WHE7178601373
A study on the expansion of the invasive grass Brachiaria spp. in Emas National Park, a critical UNESCO World Heritage Site in Brazil's Cerrado biome, reveals that internal roads and light availability are key drivers of its spread. The research found that vehicle traffic along these roads increases Brachiaria abundance tenfold compared to restricted-access areas, while open vegetation types like Campo Limpo are up to 20 times more susceptible to invasion than forested areas. Subtle slopes (around 1 degree) also direct grass expansion toward lower elevations. Using spatial-temporal data from 2002 and 2012, cellular automaton models linked these patterns to environmental variables, suggesting targeted management strategies such as road use restrictions, phytosanitary measures for visitors, and prioritization of control in open areas and declivities. This work provides actionable insights for mitigating invasive species impacts in protected areas.
Mount Etna
—
2013 —
WHE4167B24152
A study modeling the effects of seismic and magmatic activities on flank instability at Mount Etna, Italy, reveals that high-magnitude near-field earthquakes (with a return time of approximately 103 years) and vertical magma dike ascent beneath the volcano summit can induce significant strain, potentially leading to displacements of tens of centimeters in the summit area and stress releases up to 107 Pascals. These findings suggest that such events may trigger major effusive flank eruptions but do not necessarily lead to catastrophic flank collapses. The research employed a 2-D finite difference method numerical modeling approach, incorporating data on seismic actions (including near-field and far-field earthquakes) and magmatic pressure changes from lava fountains and dike ascent. Model results were validated against monitoring data and recent eruptive activity, providing insights crucial for risk assessment in densely populated volcanic regions.

Vredefort Dome
—
2013 —
WHE9B10400C78
Southern Africa's crust exhibits significant heterogeneity, with distinct blocks characterized by varying thickness and composition that do not always align with surface tectonic features. Using seismic receiver functions from 85 stations, researchers identified ~20 crustal blocks, including the Tokwe block in the Zimbabwe Craton (35–38 km thick, Vp/Vs = 1.74–1.79) and the Tati block (47–51 km thick), which may reflect Archean deformation. The Limpopo Belt shows two blocks with similar thickness but differing Vp/Vs ratios, indicating extensive magmatic intrusions. The Bushveld Intrusion Complex lacks evidence of central magmatic intrusion, suggesting its lobes formed due to a thick crustal root (45–50 km). Central Kaapvaal's thin crust (35–40 km) and sharp Moho transition may imply pre-existing lower crust delamination. Notably, the Vredefort impact crater's exposed cross-section does not represent typical cratonic crust due to shallow Moho (34 km) and high Vp/Vs (~1.80), attributed to shock metamorphism.

Komodo National Park
—
2013 —
WHE7E7AE6E8F6
A study comparing faecal counts and distance sampling found that faecal counts are more effective for monitoring low-density ungulate populations, which are key prey for the Komodo dragon (Varanus komodoensis) in Komodo National Park. The research estimated densities of rusa deer (Rusa timorensis) and feral pigs (Sus scrofa), ranging from 2.5 to 165.5 deer/km² and 0.0 to 25.2 pigs/km², respectively, with high variability. Faecal counts provided a practical alternative when densities were too low for accurate distance sampling estimates. The study also revealed nonlinear relationships between faecal and population densities for rusa deer, while feral pig data supported both linear and nonlinear models. Given the importance of ungulate density in Komodo dragon population dynamics, the authors recommend combining both methods for annual monitoring in the park.

Research on ciscoes (Coregonus) from the Solovetsky Archipelago reveals that these fish are genetically indistinguishable from the vendace (C. albula), despite intermediate morphological traits suggesting a distinct species. The study, conducted between 1995 and 2009, analyzed 344 specimens using morphological characteristics—such as vertebral count—and genetic markers, including creatine kinase alleles and mitochondrial DNA (ND-1 fragment). While the Solovetsky ciscoes exhibited traits bridging C. albula and the least cisco (C. sardinella), molecular data aligned them with the vendace, indicating that environmental adaptation likely drives morphological variation. The findings challenge traditional taxonomic distinctions, suggesting that C. albula and C. sardinella may represent a single species, C. albula.

A study of Mt. Danxia, Guangdong Province, China, reveals that the morphometric characteristics of Danxia landforms—marked by red-colored sandstones and steep cliffs—are significantly influenced by lithology and fault systems. Using GIS-based geomorphometric analyses of 42 watersheds, researchers found that hypsometric integrals (HI) reflect lithological differences between eastern and western parts of the area, while stream length gradients and Hack profiles indicate strong fault control over stream direction. This work provides a detailed quantitative assessment of Danxia landforms, offering insights into their erosional evolution and geological controls.

A morphometric analysis of the Palar sub-watershed, part of the Western Ghats in South India, reveals that the region's drainage characteristics are primarily controlled by slope and local relief, with a dendritic pattern dominating its stream network. The study, utilizing ASTER GDEM data and GIS tools, found a mean bifurcation ratio of 3.69, indicating structural control over stream development. Shape factors highlighted the elongation of the sub-watershed, while the relief ratio suggested high discharge capacity but limited groundwater potential. These findings provide critical insights for soil erosion and conservation planning in this ecologically significant UNESCO World Heritage Site.

Green turtle (Chelonia mydas) mortality at Aldabra Atoll, Seychelles, is primarily driven by entrapment and incapacitation on beach rock, with adjusted rates twice as high on the windward south coast compared to other coastal regions. Between 1995 and 2008, researchers documented 158 deaths and 50 cases of trapped or incapacitated turtles, identifying beach rock-related causes in 76% of fatal cases. Annual natural mortality is estimated at 16–30 females per year, accounting for 0.3%–1.0% of the annual nesting population. The study highlights that despite this mortality, Aldabra's green turtle population remains healthy and increasing, with no terrestrial predation. This research underscores the significance of coastal geology in shaping turtle demographics at this UNESCO World Heritage Site.
Mount Athos

Mount Athos operates under a unique 'para-sovereign' legal regime, distinct from both full autonomy and statehood. This semi-autonomous status grants it separate legislative, administrative, and judicial powers, with its governing Statute holding precedence over Greek national laws. The site's governance is deeply rooted in monastic traditions, blending religious authority with secular self-rule, yet it lacks formal statehood. While this structure ensures stability, it faces challenges from universal human rights norms that may erode its unique identity. The study analyzes the territorial status, legal position of residents and visitors, and the organization of Athos authorities to highlight its hybrid nature—neither fully independent nor entirely subservient to Greece.

European bison (Bison bonasus) movements beyond the Białowieża Forest reveal partial seasonal migrations, with males and females exhibiting distinct patterns. While male bison predominantly moved west or southwest, often alone or in small groups, females migrated north, suggesting sex-specific dispersal strategies. The study, analyzing 1,117 observations from 1964 to 2010, found that movements were strongly seasonal, peaking from November to April, and correlated with population size and snow depth. After 1990, males ventured farther (2.2 km) compared to earlier periods (0.9 km), indicating potential range expansion or habitat preference for open areas. This research highlights the dynamic behavior of reintroduced bison populations and their adaptive responses to environmental factors.

Yellowfin tuna (<em>Thunnus albacares</em>) exhibit strong fidelity to the Revillagigedo Islands Archipelago Biosphere Reserve (RIABR), Mexico, with restricted movements and low dispersion. Analysis of 16,578 days of archival tag data from 52 yellowfin tuna revealed distinct behavioral patterns linked to age, including significant differences in diving behaviors and vertical habitat utilization between day and night. The study used an unscented Kalman filter model integrated with sea-surface temperature measurements (UKFsst) to refine geographic positions and movement parameters, showing median errors of 0.46° longitude and 1.84° latitude for directed movements. These findings suggest that the oceanographic conditions surrounding the RIABR profoundly influence tuna behavior and habitat use.
