Progress in genome sequencing now enables the large-scale generation of reference genomes. Various international initiatives aim to generate genomes representing global biodiversity. These provide unique insights into genomic diversity and architecture, thereby enabling comprehensive analyses population functional genomics, are expected revolutionize conservation genomics.
Animal translocations provide striking examples of the human footprint on biodiversity. Combining continental-wide genomic and DNA-barcoding analyses, we reconstructed historical biogeography Asian black-spined toad (Duttaphrynus melanostictus), a toxic commensal amphibian that currently threatens two biodiversity hotspots through biological invasions (Wallacea Madagascar). The results emphasize complex diversification shaped by speciation mitochondrial introgression comprises distinct...
The geographic and temporal origins of Madagascar's biota have long been in the center debate. We reconstructed a time-tree including nearly all native nonflying nonmarine vertebrate clades present on island, from DNA sequences two single-copy protein-coding nuclear genes ( BDNF RAG1 ) set congruent time constraints. Reconstructions calculated with autocorrelated or independent substitution rates over agreed placing 31 included Cretaceous to Cenozoic times. sister groups South America were...
Miniaturised frogs form a fascinating but poorly understood amphibian ecomorph and have been exceptionally prone to taxonomic underestimation. The subfamily Cophylinae (family Microhylidae), endemic Madagascar, has particularly large diversity of miniaturised species which historically attributed the single genus Stumpffia largely based on their small size. Recent phylogenetic work revealed that several independent lineages cophyline microhylids evolved towards highly body sizes, achieving...
A genomic database of all Earth's eukaryotic species could contribute to many scientific discoveries; however, only a tiny fraction have information available. In 2018, scientists across the world united under Earth BioGenome Project (EBP), aiming produce high-quality reference genomes containing ~1.5 million recognized species. As European node EBP, Reference Genome Atlas (ERGA) sought implement new decentralised, equitable and inclusive model for producing genomes. For this, ERGA launched...
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed the Code has already been discussed Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; 2009a-b; Dubois Gentile Snell Minelli Cianferoni Bartolozzi 2016; Amorim et al. 2016). This was again raised a letter supported 35 signatories published journal Nature (Pape 2016) on 15 September 2016. On 25 2016,...
Abstract Amphibian chytridiomycosis, an emerging infectious disease caused by the fungus Batrachochytrium dendrobatidis ( Bd ), has been a significant driver of amphibian declines. While globally widespread, had not yet reported from within Madagascar. We document surveys conducted across country between 2005 and 2014, showing 's first record in 2010. Subsequently, was detected multiple areas, with prevalence reaching up to 100%. Detection appears be associated mid high elevation sites have...
Human activities are accelerating rates of biological invasions and climate-driven range expansions globally, yet we understand little how genomic processes facilitate the invasion process. Although most literature has focused on underlying phenotypic correlates invasiveness, advances in technologies showing a strong link between variation success. Here, consider ability tools to (i) inform mechanistic understanding (ii) solve real-world issues predicting managing invasions. For both,...
Background Nowadays, molecular techniques are widespread tools for the identification of biological entities. However, until very few years ago, their application to taxonomy provoked intense debates between traditional and taxonomists. To prevent every kind disagreement, it is essential standardize taxonomic definitions. Along these lines, we introduced concept Integrated Operational Taxonomic Unit (IOTU). IOTUs come from (OTU) paralleled Molecular (MOTU). The latter largely used as a...
The genus Scaphiophryne (Anura: Microhylidae) contains at least nine species that, together with their probable sister Paradoxophyla, form the Madagascar-endemic subfamily Scaphiophryninae. are robust burrowing frogs explosive breeding behavior and characterized by a unique larval morphology, being intermediate between that of filter-feeding generalized tadpole types. Based on nominal subgenus can be distinguished from Pseudohemisus, clade occurring in arid biomes largely unsolved taxonomy...
The Lygodactylus tolampyae complex includes several deep genetic lineages of small diurnal geckos from the West and North Madagascar whose taxonomy is largely unsolved. We sequenced DNA fragments one mitochondrial four nuclear-encoded genes for up to 70 samples across entire known range these geckos. find as many 11 differentiated by >4% pairwise distances in 16S rRNA gene fragment, with >9% distance majority lineage comparisons. Many were concordantly all without any haplotype...
The amphibian endemic fauna from Madagascar is currently facing multiple threats, including habitat loss, climate change and invasive species. Many species are listed as threatened by the IUCN, but long-term monitoring scarce assessments rarely account for population trends. Using a 13-year survey in Strict Nature Reserve of Betampona (eastern Madagascar), we assessed trends 38 between 2010 2022 based on activity. Despite high protecction status reserve, found negative trend 15 species,...
Huntington's disease is caused by a pathologically long (>35) CAG repeat located in the first exon of Huntingtin gene (HTT). While expanded repeats are focus extensive investigations, non-pathogenic tracts protein-coding genes less well characterized. Here, we investigated function and evolution physiological tract HTT gene. We show that poly-glutamine (polyQ) encoded CAGs huntingtin protein (HTT) under purifying selection subjected to stronger selective pressures than CAG-encoded polyQ...
Parasitic chytrid fungi have emerged as a significant threat to amphibian species worldwide, necessitating the development of techniques isolate these pathogens into culture for research purposes. However, early methods isolating chytrids from their hosts relied on killing amphibians. We modified pre-existing protocol infected animals use toe clips and biopsies webbing rather than euthanizing hosts, distributed researchers part BiodivERsA project RACE; here called RML protocol. In tandem, we...
A global genome database of all Earth's species diversity could be a treasure trove scientific discoveries. However, regardless the major advances in sequencing technologies, only tiny fraction have genomic information available. To contribute to more complete planetary database, scientists and institutions across world united under Earth BioGenome Project (EBP), which plans sequence assemble high-quality reference genomes for ~1.5 million recognized eukaryotic through stepwise phased...
