A 68 ka precipitation record from the hyperarid core of the Atacama Desert in northern Chile
(Elsevier, 2020-01)[Abstract] The Atacama Desert in northern Chile is one of the driest deserts on Earth. Hyperaridity persists at least since the Miocene and was punctuated by pluvial phases. However, very little is known about the timing, ... -
A Small Cretaceous Crocodyliform in a Dinosaur Nesting Ground and the Origin of Sebecids
(Springer Nature, 2020-09-17)[Abstract] Sebecosuchia was a group of highly specialized cursorial crocodyliforms that diversified during the Cretaceous and persist until the end of the Miocene. Their unique combination of cranial and post-cranial ... -
Aluminum Geochemical Characterization in Agricultural Soils: Sequential Chemical Extraction Combined With Mineralogical Analysis of the Fine Fraction
(IOP Publishing, 2020-12-15)[Abstract] Understanding both the concentration and distribution of aluminum (Al) in agricultural soils is essential to provide a benchmark on the productivity of such soils. In this study, a combination of sequential ... -
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 ... -
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 ... -
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 ... -
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 ... -
Comparing surface digitization techniques in palaeontology using visual perceptual metrics and distance computations between 3D meshes
(Wiley, 2021-01-17)[Abstract] The use of surface digitization techniques and methods in palaeontology has increased in the last two decades, mainly due to recent improvements in devices and software. However, many digitization efforts are ... -
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 ... -
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 ... -
Fossil Lagomorpha (Mammalia) of Italy: Systematics and Biochronology
(2020)[Abstract] Revisions performed in the last 15 years added remarkable novelties to the taxonomy and biochronology of Italian fossil lagomorphs. Several new taxa have been erected basing on new materials and on the revision ... -
Identification of the main driving mechanisms in the evolution of a small coastal wetland (Traba, Galicia, NW Spain) since its origin 5700 cal yr BP
(Elsevier, 2007)This paper examines the interdependence among the different forcing factors in the evolution of the Traba coastal wetland (Galicia, NW Spain) based on lithofacies and diatom analyses of three cores reaching the basement. ... -
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 ... -
Importance of the Postcranial Skeleton in Eusuchian Phylogeny: Reassessing the Systematics of Allodaposuchid Crocodylians
(PLOS, 2021-06-09)[Abstract] Our current knowledge on the crocodyliform evolution is strongly biased towards the skull morphology, and the postcranial skeleton is usually neglected in many taxonomic descriptions. However, it is logical to ... -
Lake-level and salinity reconstruction from diatom analyses in Quillagua formation (late Neogene, Central Andean forearc, northern Chile)
(Elsevier, 1999)A sedimentary and micropaleontological study of the Quillagua Formation provides a detailed paleohydrological reconstruction of the lacustrine system which occupied the present-day hyperarid Quillagua–Llamara fore-arc Basin ... -
Palaeohistology Reveals a Slow Pace of Life for the Dwarfed Sicilian Elephant
(Springer Nature, 2021-11-24)[Abstract] The 1-m-tall dwarf elephant Palaeoloxodon falconeri from the Pleistocene of Sicily (Italy) is an extreme example of insular dwarfism and epitomizes the Island Rule. Based on scaling of life-history (LH) traits ... -
Paleotsunami Evidence in the Bahía Inglesa Coast (Atacama, Chile) Based on a Multi-Approach Analysis
(Springer Nature, 2022-02-24)[Abstract] The Atacama coast is located in an area with a current high risk of tsunami, and the sedimentary deposits found in the Bahía Inglesa area, in the Morro sector, clearly indicate that this was also the case in the ... -
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. ... -
Prolagus Pomel, 1853 (Lagomorpha, Mammalia) in the Framework of the Pliocene Faunal Rearrangements in Central Europe
