Assessment and Characterisation of Ireland’s Green Tides (Ulva Species)
(PLoS, 2017)Enrichment of nutrients and metals in seawater associated with anthropogenic activities can threaten aquatic ecosystems. Consequently, nutrient and metal concentrations are parameters used to define water quality. The ... -
Regional Genetic Structure in the Aquatic Macrophyte Ruppia cirrhosa Suggests Dispersal by Waterbirds
(Springer, 2017)The evolutionary history of the genus Ruppia has been shaped by hybridization, polyploidisation and vicariance that have resulted in a problematic taxonomy. Recent studies provided insight into species circumscription, ... -
Hydrological and geochemical processes constraining groundwater salinity in wetland areas related to evaporitic (karst) systems. A case study from Southern Spain
(Elsevier, 2017)Chemical and isotopic evolution of groundwater in an evaporite karst plateau (including wetland areas and saline to hyper-saline springs) located at S Spain was studied. Physicochemical parameters, major ions and stable ... -
A new Ruscinian site in Europe: Baza-1 (Baza basin, Andalusia, Spain)
(Elsevier, 2017)The Guadix–Baza depression (southeastern Spain) preserves one of the best continental Plio-Pleistocene records of the European continent. The new site, Baza-1, is the first Ruscinian locality with fauna of large vertebrates ... -
Increased temperature and CO2 alleviate photoinhibition in Desmarestia anceps: from transcriptomics to carbon utilization
(Oxford University Press, 2017)Ocean acidification and warming are affecting polar regions with particular intensity. Rocky shores of the Antarctic Peninsula are dominated by canopy-forming Desmarestiales. This study investigates the physiological and ... -
Increased pCO2 and temperature reveal ecotypic differences in growth and photosynthetic performance of temperate and Arctic populations of Saccharina latissima
(Springer, 2017)The previous research demonstrated that warming and ocean acidification (OA) affect the biochemical composition of Arctic (Spitsbergen; SP) and cold-temperate (Helgoland; HL) Saccharina latissima differently, suggesting ... -
Inferring flight parameters of Mesozoic avians through multivariate analyses of forelimb elements in their living relatives
(Cambridge University Press, 2017-02)Our knowledge of the diversity, ecology, and phylogeny of Mesozoic birds has increased significantly during recent decades, yet our understanding of their flight competence remains poor. Wing loading (WL) and aspect ratio ... -
Aerodynamic modelling of a Cretaceous bird reveals thermal soaring capabilities during early avian evolution
(2017-07)Several flight modes are thought to have evolved during the early evolution of birds. Here, we use a combination of computational modelling and morphofunctional analyses to infer the flight properties of the raven-sized, ... -
Non-decoupled morphological evolution of the fore- and hind limb of sabretooth predators.
(Wiley, 2017-07-12)Specialized organisms are useful for exploring the combined effects of selection of functional traits and developmental constraints on patterns of phenotypic integration. Sabretooth predators are one of the most interesting ... -
Increased CO2 and iron availability effects on carbon assimilation and calcification on the formation of Emiliania huxleyi blooms in a coastal phytoplankton community
(Elsevier, 2018)In the present work, we exposed a natural phytoplankton community to either present (390-μatm, LC) or future CO2 levels predicted for year-2100 (900-μatm, HC) combined with ambient (4.5 nmol L−1, −DFB) or high (12 nmol ... -
Regional scale analysis of karst underground flow properties from tracing experiments. Examples from carbonate aquifers from Malaga province (S Spain).
(Springer, 2018-02)En esta investigación se analizan en profundidad y se aplican modelos numéricos a los datos de ensayos de trazadores artificiales (curvas de paso) obtenidos durante los últimos 15 años por miembros del Centro de Hidrogeología ... -
Flight reconstruction of two European enantiornithines (Aves, Pygostylia) and the achievement of bounding flight in Early Cretaceous birds
(Wiley, 2018-05)Intermittent flight through flap-gliding (alternating flapping phases and gliding phases with spread wings) or bounding (flapping and ballistic phases with wings folded against the body) are strategies to optimize aerial ... -
Distinct Predatory Behaviors in Scimitar- and Dirk-Toothed Sabertooth Cats.
(Cell Press, 2018-10-22)Over the Cenozoic, large cat-like forms have convergently evolved into specialized killers of “megaherbivores” that relied on their large, and laterally compressed (saber-like) canines to rapidly subdue their prey. Scimitar- ... -
Distributional shifts of canopy‑forming seaweeds from the Atlantic coast of Southern Europe
(Springer, 2019)Canopy-forming seaweeds sustain critical ecosystem services in coastal habitats. Around the world, many of these seaweeds are suffering strong declines, mainly attributed to the progressive increase in sea surface temperature, ... -
Culture of Chondracanthus teedei and Gracilariopsis longissima in a traditional salina from southern Spain
(Springer, 2019)The cultivation of two red macroalgal species, Chondracanthus teedei (Martens ex Roth) and Gracilariopsis longissima (S.G. Gmelin) Steentoft M, L.M. Irvine&W.F. Farnham, was assessed in a traditional salina, a system of ... -
Spatial and temporal variability of biomass and composition of green tides in Ireland
(Elsevier, 2019)The identification of relevant scales of variation is a necessary prerequisite before explanatory models can be proposed and tested. In this study spatial and temporal patterns of biomass distribution were assessed for two ... -
The effect of long-term atmospheric changes on the macroevolution of birds.
(Elsevier, 2019)Atmospheric conditions are critical for a range of biological functions—locomotion among others—and long-term changes in these conditions have been identified as causal for different macroevolutionary patterns. Here we ... -
The earliest cut marks of Europe: a discussion on hominin subsistence patterns in the Orce sites (Baza basin, SE Spain)
(Nature, 2019)Ancient evidence of human presence in Europe is recorded in several Early Pleistocene archaeopalaeontological sites from Spain, France and Italy. This is the case of Barranco León (BL) and Fuente Nueva-3 (FN-3), two ... -
Rubisco carboxylation kinetics and inorganic carbon utilization in polar versus cold-temperate seaweeds
(Oxford University Press, 2019)Despite the high productivity and ecological importance of seaweeds in polar coastal regions, little is known about their carbon utilization mechanisms, especially the kinetics of the CO2-fixing enzyme Rubisco. We analyzed ...
