Recent estimates suggest that the global insect fauna includes fewer than six million species, but this projection is very uncertain because taxonomic work has been limited on some highly diverse groups. Validation of current minimally requires investigation all lineages are enough to have a substantial impact final species count. This study represents first step in direction; it employs DNA barcoding evaluate patterns richness 27 orders Canadian insects. The analysis over one specimens...
The taxonomy of genus Paramyia Williston is revised for the Nearctic region north Mexico, including description (morphological and molecular) illustration 10 new species re-description nitens. Morphological keys to males females are provided. following described: anguliloba sp. n., P. brevikeraia incrassatoloba nigritarsi lustrum lutea pseudonitens silvestris rectiloba wheeleri n.. hungarica also discussed in relation species.
Comprehensive biotic surveys, or 'all taxon biodiversity inventories' (ATBI), have traditionally been limited in scale scope due to the complications surrounding specimen sorting and species identification. To circumvent these issues, several ATBI projects successfully integrated DNA barcoding into their identification procedures witnessed acceleration surveys subsequent increase project scale. The Biodiversity Institute of Ontario partnered with rare Charitable Research Reserve delegates...
Monitoring changes in terrestrial arthropod communities over space and time requires a dramatic increase the speed accuracy of processing samples that cannot be achieved with morphological approaches. The combination DNA barcoding Malaise traps allows expedited, comprehensive inventories species abundance whose cost will rapidly decline as high-throughput sequencing technologies advance. Aside from detailing protocols specimen sorting to data release, this paper describes their use survey...
Abstract The reliable taxonomic identification of organisms through DNA sequence data requires a well parameterized library curated reference sequences. However, it is estimated that just 15% described animal species are represented in public repositories. To begin to address this deficiency, we provide barcodes for 1,500,003 specimens collected from 23 terrestrial and aquatic ecozones at sites across Canada, nation comprises 7% the planet’s land surface. In total, 14 phyla, 43 classes, 163...
Abstract Global biodiversity gradients are generally expected to reflect greater species replacement closer the equator. However, empirical validation of global largely relies on vertebrates, plants, and other less diverse taxa. Here we assess temporal spatial dynamics arthropod using a beta-diversity framework. Sampling includes 129 sampling sites whereby malaise traps deployed monitor changes in communities. Overall, encountered more than 150,000 unique barcode index numbers (BINs) (i.e....
To associate specimens identified by molecular characters to other biological knowledge, we need reference sequences annotated Linnaean taxonomy. In this study, (1) report the creation of a comprehensive library DNA barcodes for arthropods an entire country (Finland), (2) publish library, and (3) deliver new identification tool insects spiders, as based on resource. The contains mtDNA COI 11,275 (43%) 26,437 arthropod species known from Finland, including 10,811 (45%) 23,956 insect species....
Climate change models often assume similar responses to temperatures across the range of a species, but local adaptation or phenotypic plasticity can lead plants and animals respond differently temperature in different parts their range. To date, there have been few tests this assumption at scale continents, so it is unclear if large-scale problem. Here, we examined that insect taxa show 96 sites grassy habitats North America. We sampled insects with Malaise traps during 2019-2021 (N = 1041...
Accurate and cost-effective methods for tracking changes in arthropod communities are needed to develop integrative environmental monitoring programs the Arctic. To date, even baseline data on their species composition at established ecological sites severely lacking. We present results of a pilot assessment non-marine diversity middle arctic tundra area near Ikaluktutiak (Cambridge Bay), Victoria Island, Nunavut, undertaken 2018 using DNA barcodes. A total 1264 Barcode Index Number (BIN)...
Although insects dominate the terrestrial fauna, sampling constraints and poor taxonomic knowledge of many groups have limited assessments their diversity. Passive techniques DNA-based species assignments now make it possible to overcome these barriers. For example, Malaise traps collect specimens with minimal intervention while Barcode Index Number (BIN) system automates assignments. The present study employs DNA barcoding extend understanding insect diversity in one least known...
Natural history collections are the physical repositories of our knowledge on species, entities biodiversity. Making this accessible to society – through, for example, digitisation or construction a validated, global DNA barcode library is crucial importance. To end, we developed and streamlined workflow ‘museum harvesting’ authoritatively identified Diptera specimens from Smithsonian Institution’s National Museum History. Our detailed includes both on-site off-site processing through...
Abstract. 1. We examined whether local assemblages of temperate forest Diptera are structured or simply random sets species, and at what scale any patterns become apparent. Nested α-, β-, γ-diversity in higher (Schizophora) were described using additive partitioning, to determine the spatial contributing most species richness. Patterns for Schizophora, two subordinate taxonomic groups (Calyptratae, Acalyptratae) common versus rare species. 2. A hierarchically nested design was used with...

Louse flies (Diptera, Hippoboscidae) are ectoparasites often found on birds. As they spend most of their life host, not collected or studied. Hence, little is known about species richness and prevalence raptors in Canada. In this study, louse were from 184 out 1467 examined during the 2020 fall migration southern Ontario, Canada, giving an overall 12.5%. total, 256 fly specimens (mean intensity = 1.41) representing four (identified morphologically, with support DNA barcoding): Icosta...
<title>Abstract</title> Global gradients in species biodiversity are expected to reflect tighter packing of closer the equator. Yet, empirical validation these patterns has so far focused on less diverse taxa, with comparable assessments mega-diverse groups historically constrained by taxonomic impediment. Here we assess temporal and spatial turnover dynamics arthropod communities sampled across 129 globally distributed monitoring sites. Overall, encountered more than 150,000 unique BINs...
Abstract The identity, richness, and abundance of true flies (Diptera) from the nests three cavity-nesting raptors (Aves) were investigated in northern Nova Scotia, Canada. After fledging, extracted nest material using Berlese funnels within an emergence chamber. Thirty-one species/morphospecies 14 families collected, including eight new records for Scotia two eastern North America.

Abstract Churchill, Manitoba, Canada is a diverse Subarctic region that has been the focus of DNA barcoding efforts and research for decades. Despite this effort, there are still taxa in underrepresented public databases, particularly hyperdiverse insect groups. We present collaborative large-scale barcode reference library Diptera based on molecular data expert taxonomic identification. The contains 16786 specimens sampled around Churchill from 2005 to 2011. Specimens were identified by...
Abstract Bird nests are fascinating microcosms harboring a wide range of arthropods parasitizing the nesting birds or feeding on prey remains, feces, and nest material. Studies these communities have been entirely based emergence traps which collect live organisms out nests. The analysis contents environmental DNA (eDNA) via metabarcoding could expand our knowledge identify prey, exuviae, other animal remains in bird Here, we investigated potential arthropod dust, feathers to better describe...
