Centennial-scale precipitation anomalies in the southern Altiplano (18° S) suggest an extratropical driver for the South American summer monsoon during the late Holocene
(European Geosciences Union, 2019-10-16)
[Abstract] Modern precipitation anomalies in the Altiplano, South America, are closely linked to the strength of the South American summer monsoon (SASM), which is influenced by large-scale climate features sourced in the ...
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 ...
Temperature effects explain continental scale distribution of cyanobacterial toxins
(MDPI, 2018-04-13)
[Abstract] Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). ...
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 ...
Diatom-inferred ecological responses of an oceanic lake system to volcanism and anthropogenic perturbations since 1290 CE
(Elsevier, 2019-07-29)
[Abstract] The impacts of natural- and human-induced processes on lake ecosystems in remote oceanic islands remain to be fully elucidated. These lakes are excellent candidates to analyze the importance of anthropogenic ...
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 ...
Evaluation of Cu and Zn Content in Soils and their Interaction with Some Physicochemical Soil Properties
(IOP Publishing, 2019-03-04)
[Abstract] The content of metals in soils depends on the combined effect of several factors, which include the properties of the metals themselves and their concentrations in the soil, environmental conditions and soil ...
