Incomplete taxon sampling due to underestimation of present-day biodiversity biases diversification analysis by favouring slowdowns in speciation rates towards the recent time. For instance, dynamics studies Crocodylia, long-term low net-diversification and have been suggested characterize crocodylian evolution. However, cryptic diversity has never considered. Here, we explore effects incorporating into a extant crocodylians. We inferred time-calibrated cryptic-species-level phylogeny using cytochrome b sequences 45 lineages compared with formally recognized 26 species. Diversification rate estimates show increasing present time, which contrasts previous findings. Cryptic should be considered future macroevolutionary analyses; however, representation extinct taxa represents major challenge. Additionally, further investigation under different underlying genomic data is encouraged upon advances population genetics. Our case study adds knowledge demonstrates that species robust taxonomic assessment are essential broad implications for evolutionary biology ecology.

ABSTRACT Aim Globally, arthropod biodiversity is under threat, with increased risk of species‐level extinctions, and this threat particularly acute on oceanic islands. A fundamental first step towards understanding extinction to understand genetic connectivity among the constituent populations a species.

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.

On a global scale, biodiversity is geographically structured into regions of biotic similarity. Delineating these has been mostly targeted for tetrapods and plants, but those hyperdiverse groups such as insects are relatively unknown. Insects may have higher biogeographic congruence with plants than due to their tight ecological evolutionary links the former, it remains untested. Here, we develop regionalization major widespread insect group, ants, based on most comprehensive distributional phylogenetic information date, examine its similarity regionalizations vascular plants. Our ant supports newly proposed Madagascan Sino-Japanese realms tetrapod delineations, recovers clusters observed in not tetrapods, Holarctic Indo-Pacific realms. Quantitative comparison suggests strong associations among different groups-plants showed ants tetrapods. These results underscore wide diverse distribution patterns across tree life similarities shared by that captured groups. analysis highlights importance developing maps obtain more geographic picture Earth.

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. While our analysis reveals significant morphological variation both yellow anacondas, denser sampling informative nuclear markers are required meaningful delimitation Eunectes.

Abstract Biodiversity is in rapid decline, but the extent of loss not well resolved for poorly known groups. We estimate number extinctions Australian non-marine invertebrates since European colonisation continent. Our analyses use a range approaches, incorporate stated uncertainties and recognise explicit caveats. plausible bounds species, two approaches estimating extinction rate, Monte Carlo simulations to select combinations projected distributions from these variables. conclude that 9,111 (plausible 1,465 56,828) species have become extinct over this 236-year period. These estimates dwarf formally recognised (10 species) single invertebrate listed as under legislation. predict 39–148 will 2024. This inconsistent with recent pledge by government prevent all extinctions. high rate largely consequence pervasive taxonomic biases community concern conservation investment. Those characteristics also make it challenging reduce loss, there uncertainty about which are at most risk. outline responses likelihood further

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

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.
