ENSO and Solar Activity Signals From Oxygen Isotopes in Diatom Silica During Late Glacial-Holocene Transition in Central Andes (18°S)
(Springer, 2010-02)
[Abstract] The late glacial-Holocene transition from the Lago Chungará sedimentary record in northern Chilean Altiplano (18°S) is made up of laminated sediments composed of light-white and dark-green pluriannual couplets ...
The Vanishing and the Establishment of a New Ecosystem on an Oceanic Island: Anthropogenic Impacts With No Return Ticket
(Elsevier, 2022-03-31)
[Abstract] A multiproxy approach was applied to a sediment core retrieved from the deep crater Lake Funda, located in the middle of the North Atlantic Ocean on Flores Island, Azores archipelago (Portugal). The purpose of ...

(National Academy of Sciences of the United States of America, 2021-08-27)
[Abstract] Humans have made such dramatic and permanent changes to Earth's landscapes that much of it is now substantially and irreversibly altered from its preanthropogenic state. Remote islands, until recently isolated ...
Long-Term Hydroclimate Variability in the Sub-Tropical North Atlantic and Anthropogenic Impacts on Lake Ecosystems: A Case Study From Flores Island, the Azores
(Elsevier, 2022-06-01)

An Assessment of the Recent Evolution of the Streamflow in a Near-Natural System: A Case Study in the Headwaters of the Mero Basin (Galicia, Spain)
(MDPI, 2020-12-08)
[Abstract] Observational trend analysis is fundamental for documenting changes in river flows and placing extreme events in their longer-term historical context. Observations from near-natural catchments, i.e., with little ...
Water Resources Response to Changes in Temperature, Rainfall and CO2 Concentration: A First Approach in NW Spain
(Multidisciplinary Digital Publishing Institute, 2014)
[Abstract] Assessment of the diverse responses of water resources to climate change and high concentrations of CO2 is crucial for the appropriate management of natural ecosystems. Despite numerous studies on the impact of ...
