Climate, catchment runoff and limnological drivers of carbon and oxygen isotope composition of diatom frustules from the central Andean Altiplano during the Lateglacial and Early Holocene
(Elsevier, 2013)
Diatom-based carbon and oxygen isotope analyses (δ13Cdiatom and δ18Odiatom) were performed on diatom-rich laminated sediments of Lake Chungará (Andean Altiplano, northern Chile) deposited during the Lateglacial and Early ...
Potential Impact of Climate Change on Suspended Sediment Yield in NW Spain: A Case Study on the Corbeira Catchment
(Multidisciplinary Digital Publishing Institute, 2016)
[Abstract] Soil losses and the subsequent sediment delivery constitute significant environmental threats. Climate change is likely to have an impact on the availability of water and therefore on sediment yield in catchments. ...
Impact of the historical introduction of exotic fishes on the chironomid community of Lake Azul (Azores Islands)
(Elsevier, 2017)
Little is known about the effect of top predator introduction in historically fishless communities, especially
on remote islands. This issue is important because it might strongly affect climate reconstructions derived
from ...
Climatic and lacustrine morphometric controls of diatom paleoproductivity in a tropical Andean lake
(Elsevier, 2015-12)
The coupling of lake dynamics with catchment biogeochemistry is considered the key element
controlling primary production in mountain lakes at time scales of a few decades to millennia, yet little
is known on the impacts ...
Biogeography and lake morphometry drive diatom and chironomid assemblages’ composition in lacustrine surface sediments of oceanic islands
(Springer, 2014)
[Abstract] Subfossil biotic assemblages in lakes’ surface sediments have been used to infer ecological conditions across environmental gradients. Local variables are usually the major drivers of assemblage composition, but ...
Biogeochemical Processes Controlling Oxygen and Carbon Isotopes of Diatom Silica in Late Glacial to Holocene Lacustrine Rhythmites
(Elsevier, 2010-05-19)
[Abstract] Biogeochemical cycles and sedimentary records in lakes are related to climate controls on hydrology and catchment processes. Changes in the isotopic composition of the diatom frustules (δ18Odiatom and δ13Cdiatom) ...
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 ...
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 ...
Challenging Easter Island’s Collapse: The Need for Interdisciplinary Synergies
(Frontiers, 2013-12-17)
[Abstract] The reigning paradigm holds that Easter Island suffered a socio-ecological collapse (ecocidal or not) sometime in the last millennium, prior to European contact (AD 1720). We discuss some novel paleoecological ...
