Evolving perspectives in Hymenoptera systematics: Bridging fossils and genomes across time

Systematic Entomology, Journal Year: 2024, Volume and Issue: unknown

Published: July 18, 2024

Abstract The recent advances in sequencing technologies, phylogenomics and divergence dating methods call for an integrative review of the current state Hymenoptera systematics. We here explore impact these latest developments on phylogeny our understanding timing evolution, while identifying methodological constraints persistent knowledge gaps that warrant further investigation. Our highlights lack consensus among backbone between key phylogenomic studies, as higher level remains unresolved nodes such relationships Eusymphyta, within Infraorder Proctotrupomorpha placements superfamilies Ichneumonoidea, Ceraphronoidea Vespoidea. Furthermore, we underline huge variation age estimates detect several major and/or disagreements fossil record available estimates, either due to poorly studied or problematic both. To better understand evolution role diversification factors, will need continuous efforts (i) reconcile conflicts morphological molecular phylogenies, by improving taxon sampling underrepresented lineages, applying novel techniques study morphology, making use genome‐scale data critically assessing incongruences genetic markers; (ii) improve record, exercising taxonomy bringing together paleontologists neontologists; (iii) relying tip approaches bridge fossils, morphology genomes across time.

How we study cryptic species and their biological implications: A case study from marine shelled gastropods

Ecology and Evolution, Journal Year: 2023, Volume and Issue: 13(9)

Published: Sept. 1, 2023

Methodological and biological considerations are intertwined when studying cryptic species. A potentially large component of modern biodiversity, the frequency species among taxonomic groups is not well documented. The term "cryptic species" imprecisely used in scientific literature, causing ambiguity interpreting their evolutionary ecological significance. This study reviews how have been defined, discussing implications for taxonomy biology, explores these with a case based on recently published literature extant shelled marine gastropods. Reviewed gastropods were recorded by Records presented authors variable levels confidence but difficult to disentangle from inherent biases effort.

How not to describe a species: lessons from a tangle of anacondas (Boidae: Eunectes Wagler, 1830)

Zoological Journal of the Linnean Society, Journal Year: 2024, Volume and Issue: 201(4)

Abstract A recent revision of the anacondas (Serpentes: Boidae: Eunectes), with description a new species green anaconda, generated extensive publicity, but also provoked considerable controversy due to inadequacies evidence used and errors in nomenclature. We here use case this problematic publication to: (i) highlight common issues affecting delimitations, especially an over-reliance on mitochondrial DNA data, reiterate best practices; (ii) reanalyse data available for establish true current state knowledge lines further research; (iii) analyse nomenclatural history status genus.

Combining new technology with classic taxonomy to overcome hurdles to discovering dark taxa

Systematics and Biodiversity, Journal Year: 2025, Volume and Issue: 23(1)

Published: Jan. 31, 2025

With numerous perils threatening biodiversity, we must remember that most of the basic units biodiversity—species—remain unknown and therefore difficult to assess. Hordes new species continue be discovered described every year. As each requires extensive work, completing description Earth's biota could require millennia, leaving many wanting automate process via genetic barcoding artificial intelligence. Over time, lesser-known groups species, referred as 'dark taxa', will occupy an increasing proportion awaiting description. dark taxa have few barcodes or images for matching algorithms, however, I propose integrating traditional taxonomy into automated workflows by linking data verified specimens using classic taxonomic keys decision trees identifying images. The roles intelligence would thus limited until can build databases specimens. This strategy vital their scientific names so signify undiscovered which is lacking in current methods.

Phylogenetic Origin of Morphologically Cryptic Species Shapes Co‐Occurrence and Sympatry Patterns

Freshwater Biology, Journal Year: 2025, Volume and Issue: 70(2)

Published: Jan. 31, 2025

ABSTRACT Cryptic species are an important part of freshwater biodiversity, yet it remains unclear how these integrate into communities from local to regional geographic scales. To protect particularly overlooked cryptic species, accurate understanding the underlying processes and adequate level protection is needed. We analysed patterns syntopies (local co‐occurrences) sympatries (regional range overlap) explore phylogenetic origin shapes biodiversity patterns. hypothesised (i) that were more common among distantly than closely related (ii) existing outcome relatedness dispersal. The hypotheses tested on a polyphyletic complex subterranean amphipod ( Niphargus rhenorhodanensis complex) by deploying molecular delimitation, time‐calibrated phylogenies, co‐occurrence analyses with probabilistic generalised linear models (GLM). studied comprised 37–48 operational taxonomic units (MOTUs) nine different clades, occurring at random or less frequently expected. GLM indicated age divergence did not predict sympatries, although they emerged MOTUs clades. Sympatries, however, through dispersal, in large ranges. These mostly overlapped foothills Alps, Jura Central Massif. conclude observed spatial mainly driven dispersal presumably reflect circumstances speciation. While richness scale may be competition arise clade‐level cascade historical events, including orogeny climatic shifts.
