Geochemical analysis of Cenozoic fossil conifers at high latitudes: Implications for molecular preservation and environmental change [PDF]

open access: yes, 2010
Fossil materials record ancient life and their adapted environment. Arctic plant fossils are critical for our understanding of the Earth’s paleoenvironment when high latitudes were under ice-free conditions.

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Optimizing the water-ecosystem-food nexus using nature-based solutions at the basin scale

open access: yesFrontiers in Water
The water ecosystem food (WEF) nexus duly acknowledges the complex interdependencies among water, ecosystems, and food production, underscoring nature based solutions (NBS) as an efficacious strategy for navigating these interconnections.

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Box Models of Volatile Cycles over the Entire Phanerozoic [PDF]

open access: yes, 2006
Three stand-alone geochemical box models have been developed to simulate globally coupled biogeochemical cycles. These models reflect the evolution of the participating biotic and abiotic constituents in marine and terrestrial environments, including the

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

Preliminary validation of an indirect method for discharge evaluation of Pertuso Spring (Central Italy) [PDF]

open access: yes, 2016
This paper deals with the results of the first year of the Environmental Monitoring Plan, related to the catchment project of Pertuso Spring, which is going to be exploited to supply an important water network in the South part of Roma district.
