Introduction
I am a Biodiversity Scientist. I have a strong interest in genomics and large datasets, as my work focuses on phylogenomics with the goal of improving the knowledge of the relationships of species. I am also interested in understanding how evolutionary processes have shaped patterns of modern biodiversity in a range of species. I am leading phylogenomic analyses to infer the relationship amongst the tribe Vrieseinae (bromeliads, plants) at the University of Gothenburg (Sweden) using genomics.

The Needle-billed Hermit Phaethornis philippii is a monotypic species of hummingbird, endemic to the humid forests of western and Central Amazonia. It occurs in eastern Peru, northern Bolivia and part of Brazil, south of the Solimões and the Amazon rivers and west of the Tapajós River. Despite being included in some previous works, the evolutionary...
Background
The genus Caspiomyzon is comprised of three species, two of which are found in Greece (Caspiomyzon hellenicus and Caspiomyzon graecus). Both species are endemic with very restricted distribution and are classified as Critically Endangered. Caspiomyzon hellenicus is restricted to Tenagi, Philippi and C. graecus to Louros River. No studies...
Aim
The central and western Amazonia underwent several landscape changes during the Quaternary. Whereas the Riverine Barrier Hypothesis is traditionally used to explain the influence of rivers on speciation, processes such as river rearrangements have been overlooked to explain the geographic distribution and evolutionary history of Amazonia biota....
Dental topographic metrics (DTMs), which quantify different aspects of the shape of teeth, are powerful tools for studying dietary adaptation and evolution in mammals. Current DTM protocols usually rely on proprietary software, which may be unavailable to researchers for reasons of cost. We address this issue in the context of a DTM analysis of the...
Geographic barriers are frequently invoked to explain genetic structuring across the landscape. However, inferences on the spatial and temporal origins of population variation have been largely limited to evolutionary neutral models, ignoring the potential role of natural selection and intrinsic genomic processes known as genomic architecture in pr...
Areas of endemism are the smallest units in biogeography and can be defined as biologically unique areas comprising taxa with common geographic limits to their distributions. High beta diversity within Amazonia is often related to turnover among these areas. For decades, evolutionary biologists have tried to comprehend the mechanisms generating and...
Dental topographic metrics (DTMs), which quantify different aspects of the shape of teeth, are powerful tools for studying dietary adaptation and evolution in mammals. However, comparative samples of scanned mammal teeth suitable for analysis with DTMs remain limited in size and scope, with little or no representation of some major lineages, even w...

Aim
Western Amazonia is a region that underwent several landscape changes during the Quaternary. While Riverine Barrier Hypothesis is traditionally used to explain the influence of rivers on speciation, processes such as river rearrangements have been overlooked to explain the geographic distribution and evolutionary history of the Amazonia biota....
Although the importance of fishing resources in the Amazon is recognized, statistical data on total fish production by region in Brazil is lacking. Despite being a symbol of folklore and popular culture in the Amazon region, knowledge about Hypophthalmus fishes (mapará) is still scarce. The genus is currently considered to contain six species: H. m...
The genus Willisornis is endemic to the Amazon Basin, inhabiting upland terra firme forest, with two species and seven subspecies currently recognized. Despite numerous systematic studies, a taxonomically-dense sampled phylogeny for Willisornis is still lacking, which, combined with evidence of paraphyly and gene flow between its recognized species...

Target sequence capture has emerged as a powerful method to sequence hundreds or thousands of genomic regions in a cost- and time-efficient approach. In most cases, however, targeted regions lack full sequence information for certain samples, due to taxonomic, laboratory, or stochastic factors. Loci lacking molecular data for a large number of samp...
The use of Ultraconserved Elements (UCEs) as genetic markers in phylogenomics has become popular and has provided promising results. Although UCE data can be easily obtained from targeted enriched sequencing, the protocol for in silico analysis of UCEs consist of the execution of heterogeneous and complex tools, a challenge for scientists without t...
Large rivers are ubiquitously invoked to explain the distributional limits and speciation of the Amazon Basin's mega-diversity. However, inferences on the spatial and temporal origins of Amazonian species have narrowly focused on evolutionary neutral models, ignoring the potential role of natural selection and intrinsic genomic processes known to p...
The Asian and Australo‐Papuan faunas meet and intermix across the islands of Wallacea. Untangling the origins and relationships of the species inhabiting these archipelagos is an ongoing project that has lasted for well over a century. In recent years, molecular phylogenetic studies have made considerable progress in clarifying the affinities of en...
Rays (Batoidea) are among the most threatened groups of vertebrates. Slow growth and low fecundity make many species vulnerable to overfishing, but increased demand for gill rakers in traditional Chinese medicine and elasmobranch meat means exploitation continues. In response, protection has increased, with manta and devilrays (Mobulidae) and sawfi...
The true diversity and interspecific limits in the Neotropical endemic avian genus Dendrocolaptes (Furnariidae) remain a highly controversial subject, with previous genus‐wide assessments, based mostly on morphological characters, producing poorly resolved phylogenies. The lack of well‐resolved, robust, and taxonomically densely sampled phylogenies...
High-throughput DNA sequencing techniques enable time- and cost-effective sequencing of large portions of the genome. Instead of sequencing and annotating whole genomes, many phylogenetic studies focus sequencing effort on large sets of pre-selected loci, which further reduces costs and bioinformatic challenges while increasing coverage. One common...
To elucidate the relationships and spatial range evolution across the world of the bird genus Turdus (Aves), we produced a large genomic dataset comprising ca 2 million nucleotides for ca 100 samples representing 53 species, including over 2000 loci. We estimated time-calibrated maximum-likelihood and multispecies coalescent phylogenies and carried...

The Amazon is the primary source of Neotropical diversity and a nexus for discussions on processes that drive biotic diversification. Biogeographers have focused on the roles of rivers and Pleistocene climate change in explaining high rates of speciation. We combine phylogeographic and niche-based paleodistributional projections for 23 upland terra...
