Classify viruses — the gain is worth the pain 2019-02-19T05:00:00Z It is important to note that although sister taxa and polytomy do share an ancestor, it does not mean that the groups of organisms split or evolved from each other. Biology for AP Courses 2022-06-09T00:00:00Z Hunt had been focusing on fossil ostracods – one of the few taxa where sexual dimorphism can be readily identified in the fossil record. When evolution’s path leads to a dead end 2018-06-08T04:00:00Z The bulk of the book is made up of chapters that report new material and/or review previously named taxa.

Artist resurrects obscure fossils in gorgeous living colour 2018-02-28T05:00:00Z None of these taxa is at all birdlike and all clearly belong elsewhere in reptile phylogeny. The "Birds Are Not Dinosaurs" Movement 2017-11-23T05:00:00Z By focusing attention on taxon expansion rather than survival, we resolve an apparent contradiction between the seemingly deterministic waxing and waning patterns over time and the randomness of extinction that the Red Queen’s hypothesis implies. Reconciling taxon senescence with the Red Queen’s hypothesis 2017-11-28T05:00:00Z For example, if a branch point was rotated and the taxon order changed, this would not alter the information because the evolution of each taxon from the branch point was independent of the other. Biology for AP Courses 2022-06-09T00:00:00Z Furthermore, which lineages or populations should be recognised as taxa – and which rank those taxa should be awarded – remains one of the greatest areas of disagreement and argument in zoology. The Tiger Subspecies Revised, 2017 2017-11-23T05:00:00Z If turnover dominates, then disparate communities will harbour unique taxa. A communal catalogue reveals Earth’s multiscale microbial diversity 2017-10-31T04:00:00Z Birds and mammals are reported as separate taxa, and species names are listed in alphabetical order within each of those subdivisions. Reductions in global biodiversity loss predicted from conservation spending 2017-10-24T04:00:00Z To a first approximation, we find that biotic drivers of evolution pertain mainly to the peak of taxon expansion, whereas abiotic drivers mainly apply to taxon extinction. Reconciling taxon senescence with the Red Queen’s hypothesis 2017-11-28T05:00:00Z On the other hand, there are perhaps enough differences that allow us to extract some taxa from the mess. The Fall and Rise of Protoichthyosaurus 2017-10-15T04:00:00Z This is true both for individual specimens or for species, given the plesiosaur species count depends on the scientific philosophy of how taxa are distinguished from each other. Just How Good Is the Plesiosaur Fossil Record? 2017-10-14T04:00:00Z If nestedness dominates, then communities with fewer taxa will be subsets of communities with more taxa. A communal catalogue reveals Earth’s multiscale microbial diversity 2017-10-31T04:00:00Z But the data also point to a need to focus conservation efforts on neglected taxa. World’s botanic gardens should work together 2017-09-24T04:00:00Z This pattern appears to contradict the law of constant extinction1, which states that the probability of extinction in a given taxon is independent of that taxon’s age. Reconciling taxon senescence with the Red Queen’s hypothesis 2017-11-28T05:00:00Z The researchers also found at least 57 different plant taxa in the dung deposit, from conifer cones and wild plum to ash and pokeweed. Talking Crap about Mastodons 2017-09-10T04:00:00Z It would also boost incentives to provide and refine tools for recognizing and delimiting taxa and to deal with biodiversity beyond the category we designate as 'species'. Taxonomy: stable taxon boundaries : Nature : Nature Research 2017-08-08T04:00:00Z Given the contrasting environments and geographic separation among the many studies in the EMP, we expected different environments to contain unique sets of taxa and to show little nestedness.

Fossils We Want To Find 2017-07-23T04:00:00Z In some taxa, the sinus is completely roofed over by bone, only the circular fontanelle being present. The Supracranial Sinus of the Horned Dinosaur Skull 2017-07-22T04:00:00Z The team led by Dell’Ariccia argue that splitting the world’s oceans into nine overlapping regions was likely to ‘severely reduce statistical power’, and the pooled data would ‘obscure biologically meaningful patterns among taxa’. Skeptics Poke Holes in Claim That Birds Mistake Plastic for Food 2017-07-06T04:00:00Z We therefore suggest that, instead of listing and protecting species names, conservation should introduce the practice of referencing the taxonomic treatments used to apply the names to specific taxon concepts. Taxonomy: stable taxon boundaries : Nature : Nature Research 2017-08-08T04:00:00Z As an example, we applied a Shannon entropy analysis to tag sequences and higher taxonomic groups to measure biases in the distribution of taxa.

Nomenclature: Rules for new species from live specimens : Nature : Nature Research 2017-06-06T04:00:00Z The taxon names themselves are stable because they are defined solely by their type — such as a type specimen, a drawing of a species, or the genus that typifies a family. Taxonomy: stable taxon boundaries : Nature : Nature Research 2017-08-08T04:00:00Z More recent studies not included in this meta-analysis adopted additional primer modifications to allow recovery of key taxa in marine and soil samples17,18,19. A communal catalogue reveals Earth’s multiscale microbial diversity 2017-10-31T04:00:00Z They argue that DNA evidence indicates that it is not a valid taxon. Taxonomy anarchy hampers conservation Abrogast’s new study shows, in fact, that the two species are closely related—sister taxa, as scientists say. Meet This Newly Discovered Flying Squirrel Ethically responsible taxonomists do not alter photos, use others' photos without permission, or pre-emptively publish names for taxa others are working on. Nomenclature: Rules for new species from live specimens : Nature : Nature Research 2017-06-06T04:00:00Z This practice would provide stability for taxon boundaries in efforts to conserve biodiversity.
