“…OBJECTIVE: To assess the in vitro efficacy on antioxidant potential, protection against global oxidative stress, and effect on collagen neosynthesis of minimalist formula (Peptide‐C ampoules product) containing 10% natural vitamin C, rice and lupin bio‐peptides, hyaluronic acid, and Vichy volcanic mineralizing water (active mix). METHODS: In‐tube quantitative tests (“in‐tube screening”) assessed global antioxidant properties, anti‐lipid peroxidation, anti‐protein glycosylation, and metalloproteinase inhibition (anti‐collagenase, anti‐elastase, and anti‐hyaluronidase activity) properties of the formula. …”

“…We explored various competing demographypotheses to account for the rapid divergence of a fir species complex (Abies flinckii–A. religiosa) distributed in “sky‐islands” across central Mexico (i.e., along the Trans‐Mexican Volcanic Belt; TMVB). Despite co‐occurring in two independent sympatric regions (west and centre), these taxa rarely interbreed because of disjunct reproductive phenologies. …”

“…These routes are separated by low-lying, equatorial atolls that were settled during secondary migrations ~1,000 y later after their exposure by relative sea-level fall from a mid-Holocene highstand. High volcanic islands in the Federated States of Micronesia (Pohnpei and Kosrae) also lie between the migration routes and settlement is thought to have occurred during the secondary migrations despite having been above sea level during the initial settlement of Remote Oceania. …”

“…In its natural distribution, Araucaria araucana is a plant species usually exposed to extreme environmental constraints such as wind, volcanism, fires, and low rainfall. This plant is subjected to long periods of drought, accentuated by the current climate emergency, causing plant death, especially in its early growth stages. …”

“…Quantifying and forecasting the evolution of rock physical and mechanical parameters with temperature is thus crucial for evaluating rock integrity in many applications such as geothermal fields, nuclear waste storage, wildfire or volcanic processes. In marbles the degree of previous exposure to temperature and the chemical composition (i.e. calcite vs dolomite) plays a key role for controlling the mechanical evolution under temperature. …”

“…In the case of Marchena, simultaneous changes to both nuclear and mitochondrial DNA variation may also be the result of a volcanic eruption on the island in 1991. Therefore, studies that seek to evaluate the genetic impact of El Niño must also consider the confounding or potentially synergistic effect of other environmental and biological forces shaping populations.…”

“…Our new data sets demonstrate that the main axis of the volcanic arc in southern Central America more than likely existed as a peninsula connected to northern Central America and North America for much of the Miocene, which has profound implications for our understanding of the tectonic, climatic, oceanographic and biogeographic history related to the formation of the Isthmus of Panama.…”
