The current distributions of widespread groups terrestrial animals and plants are supposedly the result a mixture either vicariance owing to continental split or more recent trans-oceanic dispersal. For organisms exhibiting vicariant biogeographic pattern—achieving their distribution by riding on plates former supercontinents—this view is largely inspired belief that Pangaea lacked geographical ecological barriers, extinctions dispersal would have erased any signal since early Mesozoic. We...
The genus Dyscolus Dejean, 1831 is a highly speciose taxon of neotropical Carabidae and the major component high-altitude ground beetle communities in tropical Andes. aim this study threefold: (i) refine taxonomic position equatorial members using molecular data, (ii) provide delimitation species found Ecuador páramo montane forest environments based on robust combination morphological (iii) describe new take nomenclatural decisions made necessary by results study. seclusion from more basal...
Abstract Ecological and evolutionary theories have proposed that species traits should be important in mediating responses to contemporary climate change; yet, empirical evidence has so far provided mixed for the role of behavioral, life history, or ecological characteristics facilitating hindering range shifts. As such, utility trait‐based approaches predict redistribution under change been called into question. We develop perspective, supported by evidence, trait variation, if used...
We investigate the phylogeny, biogeography, time of origin and diversification, ancestral area reconstruction large-scale distributional patterns an ancient group arachnids, harvestman suborder Cyphophthalmi. Analysis molecular morphological data allow us to propose a new classification system for group; Pettalidae constitutes infraorder Scopulophthalmi clade, sister all other families, which are divided into infraorders Sternophthalmi clade Boreophthalmi clade. includes families...
Museum collections are essential for understanding biodiversity and next-generation sequencing methods (NGS) offer new opportunities to generate genomic data on specimens of extinct species phylogenetic other studies. Hesperelaea is a monotypic Oleaceae genus that was collected only once, 140 years ago Guadalupe Island, Mexico. This lineage almost certainly extinct, has been considered an insular paleoendemic unknown relationship within subtribe Oleinae. Here, genome skimming approach...
In the current context of global change and human-induced biodiversity decline, there is an urgent need for developing sampling approaches able to accurately describe state biodiversity. Traditional surveys vertebrate fauna involve time-consuming skill-demanding field methods. Recently, use DNA derived from invertebrate parasites (leeches blowflies) was suggested as a new tool diversity assessment. Bloodmeal analyses arthropod disease vectors have long been performed their feeding behaviour,...
Abstract Assessing the impact of human activity on ecosystems often links local biodiversity to disturbances measured within same locality. However, remote may also affect biodiversity. Here, we used environmental DNA metabarcoding evaluate relationships between vertebrate (fish and mammals) disturbance intensity in two Amazonian rivers. Measurements anthropic -here forest cover losses- were made from immediate vicinity sampling sites up 90 km upstream. The findings suggest that...
Abstract Changes in biodiversity may impact infectious disease transmission through multiple mechanisms. We explored the of changes on Amazonian leishmaniases, a group wild zoonoses transmitted by phlebotomine sand flies (Psychodidae), which represent an important health burden region where is both rich and threatened. Using molecular analyses fly pools blood‐fed dipterans, we characterized system forest sites French Guiana undergoing different levels human‐induced disturbance. show that...
Abstract New Caledonia is well known as a hot spot of biodiversity whose origin land mass can be traced back to the Gondwanan supercontinent. The local flora and fauna, in addition being remarkably rich endemic, comprise many supposedly relictual groups. Does Caledonian biota date times, building up its richness endemism over 100 Myr or does it result from recent diversifications after Tertiary geological catastrophic events? Here we use molecular phylogenetic approach answer this question...
Environmental DNA (eDNA) is gaining a growing popularity among scientists but its applicability to biodiversity research and management remains limited in river systems by the lack of knowledge about spatial extent downstream transport eDNA. Here, we assessed ability eDNA inventories retrieve patterns fish assemblages along two large species-rich Neotropical rivers. We first examined overall community variation with distance through decay similarity compared this pattern capture-based...
The patterns of local endemism in New Caledonia were analysed two endemic genera Tingidae (Insecta, Heteroptera), Cephalidiosus and Nobarnus, through a phylogenetic analysis species' distribution modelling. aim was to determine the possible causes diversification Caledonia. Our results show that environmental conditions are probably important for genus Cephalidiosus, conjunction with other factors such as resource (host plant) distribution, but suggest same have not influenced speciation...
The high diversity of New Caledonia has traditionally been seen as a result its Gondwanan origin, old age and long isolation under stable climatic conditions (the museum model). Under this scenario, we would expect species diversification to follow constant rate model. Alternatively, if was completely submerged after breakup from Gondwana, geological evidence indicates, show characteristic slowdown over time according diversity-dependent model where accumulation decreases space is filled. We...
Summary DNA barcoding and metabarcoding are increasingly used as alternatives to traditional morphological identifications. For animals, the standard barcode is a c. 658‐bp portion of COI gene, for which reference libraries now cover large proportion described mammal species. Unfortunately, because its sequence too long does not contain highly conserved primer binding sites, this marker adapted metabarcoding. Although alternative metabarcodes have been developed, their performances generally...
Abstract Phlebotomine sand flies are haematophagous dipterans of primary medical importance. They represent the only proven vectors leishmaniasis worldwide and involved in transmission various other pathogens. Studying ecology is crucial to understand epidemiology further control this disease. A major limitation regard that traditional morphological‐based methods for fly species identifications time‐consuming require taxonomic expertise. DNA metabarcoding holds great promise overcoming issue...
