Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

open access: yesJournal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Structural Uncertainty in the Sensitivity of Urban Temperatures to Anthropogenic Heat Flux

open access: yesJournal of Advances in Modeling Earth Systems
One key source of uncertainty for weather and climate models is structural uncertainty arising from the fact that these models must simplify or approximate complex physical, chemical, and biological processes that occur in the real world.

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

Canopy Temperature as a Water Stress Indicator in Vines

open access: yesSouth African Journal of Enology & Viticulture, 2017
Canopy temperature (CT) of vine plots subjected to drying cycles, and of well-watered control plots was measured with the aid of an infra-red thermometer in a full-bearing Colombar vineyard together with measurements of leaf water potential (LWP) and stomata) resistance (Rs). A decrease in transpiration rate due to water stress caused plant temperature
