Regional distribution of carbapenemase-producing Acinetobacter baumannii isolates in southern Spain (Andalusia)NARA Subscribed
Objectives This is the first study conducted in southern Spain to determine i) the population structure (PS) of carbapenem-resistant (CR) Acinetobacter baumannii isolates by multilocus sequencing typing (MLST) and core genome MLST (cgMLST) and ii) the association between the sequence type ST and the bla OXA-51 variant, capsule polysaccharide locus (KL) and lipooligosaccharide outer core locus (OCL) types. Methods Of 336 isolat...
Geography and ecology shape the phylogenetic composition of Amazonian tree communitiesNARA Subscribed
Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location Amazonia. Taxon A...
Ancient DNA reveals interstadials as a driver of common vole population dynamics during the last glacial periodNARA Subscribed
Aim Many species experienced population turnover and local extinction during the Late Pleistocene. In the case of megafauna, it remains challenging to disentangle climate change and the activities of Palaeolithic hunter‐gatherers as the main cause. In contrast, the impact of humans on rodent populations is likely to be negligible. This study investigated which climatic and/or environmental factors affect the population dynamic...
Geographic patterns of tree dispersal modes in Amazonia and their ecological correlatesNARA Subscribed
Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser‐availability hypothesis) and/or the availability of resources for constructing zoocho...
Scaling issues of neutral theory reveal violations of ecological equivalence for dominant Amazonian tree speciesNARA Subscribed
Neutral models are often used as null models, testing the relative importance of niche versus neutral processes in shaping diversity. Most versions, however, focus only on regional scale predictions and neglect local level contributions. Recently, a new formulation of spatial neutral theory was published showing an incompatibility between regional and local scale fits where especially the number of rare species was dramaticall...
In 2007, remains of Mammuthus meridionalis and 334 lithic artefacts were recovered in level 2 of Barranc de la Boella. The presence of M. meridionalis allows us to assign an age older than 700 ka to this level, which represents one of the few sites of this age with palaeontological remains associated with lithic industry. It also enables us to shed light on questions pertaining to the chronology and the biogeography of the ear...
