FILL-IN DEFINITIONS (2 pts. eaCh) 15. SPECIATION: the splitting of one evolutionary lineage into two or more. 16. PHENETICS: field of study that classifies species solely according to their overall physical similarity to other species. 17. SYNAPOMORPHIES: shared, derived characters that are weighted heavily in a cladistic analysis. 2 18. POLYMORPHISM: two or more discrete phenotypes in a sympatric population. 19. PTERYLAE: feather tracts, i.e., specific regions from which feathers grow on the skin of most birds. 20. MICROSATELLITES: repeated sequences of 1–6 base pairs of dNA. These sequences have high mutation rates resulting in many polymorphisms that can indicate genetic diversity within populations of the same species. SHORT ANSWER 21. Of the 8 modifications of the AXIAL skeleton in birds compared to ancestral reptiles, e.g., Cotylosaurs, list any 4. (Note: Be not vague! If you think some modification of the tail has occurred, then describe that modification. You will get no credit for simply writing the word “tail”.) (4 pts) Axial skeleton Includes skull, all vertebrae (cervical, dorsal {thoracic, lumbar}, sacral and caudal), ribCage, and sternum. *Secondary bony palate *Hingelike ankle - no lateral movement *3-fingered hand, 4-toed foot *High metabolism *Semi-lunate carpal *Big eyes, big brains *Furcula *FEATHERS! *Bladelike scapula 22. Of the 9 functions of feathers that have nothing to do with flight (flight is the 10th), list any 4 and provide an example of each. (Again, be not vague.) (4 pts) Feather functions: •insulation (e.g., nestlings) •waterproofing (e.g., Common Loon) •crypsis (e.g., owls, nestlings) •display (e.g., general display of health and vigor: •flight pink color of Greater Flamingo) •species/gender recognition (e.g., sexually •Gathering food (e.g., rictal bristles) dimorphic species like Red-winged Blackbird) •Gathering water (e.g., modified belly feathers of •special display (e.g., modified feathers of Club- sandgrouse) winged Manakin, Marvelous Spatuletail) •Perch prop (e.g., woodpeckers) 23. There are three groups of vertebrates (besides flying fish!) that independently evolved powered flight. What are those three groups of organisms? discuss the analogous and homologous structures in these groups that power their flight. (6 pts – please write out this answer in complete sentences.) Powered flight arose independently among the birds, pterosaurs, and the bats. In these groups, their wings are analogous structures, because the flying membrane is unique to each group: feathers supported by the arm in birds, skin supported by the hand in bats, and skin supported one enormous digit in the pterosaurs. The bones of the arm and hand, however, are homologous among all three groups: humerus, radius, ulna, carpals, metacarpals, and phalanges can be found in each group. 3 24. The following cladogram of a hypothetical taxon includes species a–l. Draw a line around any polyphyletic group on this cladogram. What criterion identifies your group as polyphyletic? Provide an example of a real- life polyphyletic group, and why it is polyphyletic. (6 pts – please write out this answer in complete sentences.) d e g h k l C f j b a A polyphyletic group does not arise from a single, common ancestor. In the example above, h and k are polyphyletic as a taxon because their grouping does not include their immediate common ancestors of a. In fact, h and k have different immediate ancestors that are not in the taxon. Polyphyletic taxa have their place: flowering plants and mosses arose from different common ancestors, so any kingdom of plants that includes mosses and flowering plants is a polyphyletic grouping, not a monophyletic one. Thus, recognition of plants as a kingdom is not in keeping with a cladistic approach to systematics, but we still find it useful as both groups are sessile, conduct photosynthesis, etc. Among birds, the old order Falconiformes we now know to be polyphyletic because genomic sequencing has revealed that falcons are not closely related to hawks, eagles, etc. Total Points: _____46______/40 (46 possible!) 4 .

    Article Dense sampling of bird diversity increases power of comparative genomics https://doi.org/10.1038/s41586-020-2873-9 A list of authors and affiliations appears at the end of the paper. Received: 9 August 2019 Whole-genome sequencing projects are increasingly populating the tree of life and Accepted: 27 July 2020 characterizing biodiversity1–4. Sparse taxon sampling has previously been proposed Published online: 11 November 2020 to confound phylogenetic inference5, and captures only a fraction of the genomic Open access diversity. Here we report a substantial step towards the dense representation of avian phylogenetic and molecular diversity, by analysing 363 genomes from 92.4% of bird Check for updates families—including 267 newly sequenced genomes produced for phase II of the Bird 10,000 Genomes (B10K) Project. We use this comparative genome dataset in combination with a pipeline that leverages a reference-free whole-genome alignment to identify orthologous regions in greater numbers than has previously been possible and to recognize genomic novelties in particular bird lineages. The densely sampled alignment provides a single-base-pair map of selection, has more than doubled the fraction of bases that are confdently predicted to be under conservation and reveals extensive patterns of weak selection in predominantly non-coding DNA. Our results demonstrate that increasing the diversity of genomes used in comparative studies can reveal more shared and lineage-specifc variation, and improve the investigation of genomic characteristics. We anticipate that this genomic resource will ofer new perspectives on evolutionary processes in cross-species comparative analyses and assist in eforts to conserve species.

  • ECDC/EFSA Joint Report: Avian Influenza Overview October
    SCIENTIFIC REPORT APPROVED: 29 September 2017 doi: 10.2903/j.efsa.2017.5018 Avian influenza overview October 2016–August 2017 European Food Safety Authority, European Centre for Disease Prevention and Control, European Union Reference Laboratory for Avian influenza, Ian Brown, Paolo Mulatti, Krzysztof Smietanka, Christoph Staubach, Preben Willeberg, Cornelia Adlhoch, Denise Candiani, Chiara Fabris, Gabriele Zancanaro, Joana Morgado and Frank Verdonck Abstract The A(H5N8) highly pathogenic avian influenza (HPAI) epidemic occurred in 29 European countries in 2016/2017 and has been the largest ever recorded in the EU in terms of number of poultry outbreaks, geographical extent and number of dead wild birds. Multiple primary incursions temporally related with all major poultry sectors affected but secondary spread was most commonly associated with domestic waterfowl species. A massive effort of all the affected EU Member States (MSs) allowed a descriptive epidemiological overview of the cases in poultry, captive birds and wild birds, providing also information on measures applied at the individual MS level. Data on poultry population structure are required to facilitate data and risk factor analysis, hence to strengthen science-based advice to risk managers. It is suggested to promote common understanding and application of definitions related to control activities and their reporting across MSs. Despite a large number of human exposures to infected poultry occurred during the ongoing outbreaks, no transmission to humans has been identified. Monitoring the avian influenza (AI) situation in other continents indicated a potential risk of long-distance spread of HPAI virus (HPAIV) A(H5N6) from Asia to wintering grounds towards Western Europe, similarly to what happened with HPAIV A(H5N8) and HPAIV A(H5N1) in previous years.

  • Data Types and the Phylogeny of Neoaves
    Article Data Types and the Phylogeny of Neoaves Edward L. Braun * and Rebecca T. Kimball * Department of Biology, University of Florida, Gainesville, FL 32611, USA * Correspondence: ebraun68@ufl.edu (E.L.B.); rkimball@ufl.edu (R.T.K.) Simple Summary: Some of the earliest studies using molecular data to resolve evolutionary history separated birds into three main groups: Paleognathae (ostriches and allies), Galloanseres (ducks and chickens), and Neoaves (the remaining ~95% of avian species). The early evolution of Neoaves, however, has remained challenging to understand, even as data from whole genomes have become available. We have recently proposed that some of the conflicts among recent studies may be due to the type of genomic data that is analyzed (regions that code for proteins versus regions that do not). However, a rigorous examination of this hypothesis using coding and non-coding data from the same genomic regions sequenced from a relatively large number of species has not yet been conducted. Here we perform such an analysis and show that data type does influence the methods used to infer evolutionary relationships from molecular sequences. We also show that conducting analyses using models of sequence evolution that were chosen to minimize reconstruction errors result in coding and non-coding trees that are much more similar, and we add to the evidence that non-coding data provide better information regarding neoavian relationships. While a few relationships remain problematic, we are approaching a good understanding of the evolutionary history for major avian groups. Abstract: The phylogeny of Neoaves, the largest clade of extant birds, has remained unclear despite intense study.

  • Global Diversity of Birds 2015
    Ornithology NREM/ZOOL 4464 Dr. Tim O’Connell Spring 2015 A Classification of Birds of the World – Laboratory Investigations As students of Ornithology, a primary objective for you is to develop a working knowledge of the diversity of birds of the world. As you internalize this information, you will develop a deep appreciation for the central role that evolution plays as the driver of biological diversity. We begin this week in Lab to really explore the diversity of birds through in-depth examination of orders and families. Avian classification is fluid: the ordering and alliance of families and orders differs according to different authorities and new information is continually becoming available that enhances our ability to discern relationships; this results in updated classifications. You are embarking on this voyage during a time of significant taxonomic revision, and much of what you will learn in Lab supersedes classification systems in your field guides. Different authorities (usually committees) often disagree in their assessment of a taxon. Where one authority might recognize a full species, another might recognize it as a subspecies of some other species. Higher-level assignments are tricky too, e.g., some place the South American rheas in their own order (Rheiformes) whereas others lump it in with other ostrich-like birds in Struthioniformes. The American Ornithologists’ Union manages two committees (North American and South American Classification Committees) that review information and render decisions on which taxonomic proposals will be recognized. Each July, the AOU publishes updates to its official checklist. That checklist is commonly accessed via a massive book containing information on distribution, evolutionary affinities, etc.

Over the past two de- cades, a wealth of new fossil discoveries and phylogenetic and macroevolutionary studies has transformed our understanding of how birds originated and became so successful. Birds evolved from theropod dino- saurs during the Jurassic (around 165–150 million years ago) and their classic small, lightweight, feathered, and winged body plan was pieced together gradually over tens of millions of years of evolution rather than in one burst of innovation. Early birds diversified throughout the Jurassic and Cretaceous, becoming capable fliers with supercharged growth rates, but were decimated at the end-Cretaceous extinction alongside their close dinosaurian relatives. After the mass extinction, modern birds (members of the avian crown group) explosively diversified, culminating in more than 10,000 species distributed worldwide today.

Received: 3 June 2019; Accepted: 4 July 2019; Published: 6 July 2019 Abstract: The early radiation of Neoaves has been hypothesized to be an intractable “hard polytomy”. We explore the fundamental properties of insertion/deletion alleles (indels), an under-utilized form of genomic data with the potential to help solve this. We scored >5 million indels from >7000 pan-genomic intronic and ultraconserved element (UCE) loci in 48 representatives of all neoavian orders. We found that intronic and UCE indels exhibited less homoplasy than nucleotide (nt) data. Gene trees estimated using indel data were less resolved than those estimated using nt data. Nevertheless, Accurate Species TRee Algorithm (ASTRAL) species trees estimated using indels were generally similar to nt-based ASTRAL trees, albeit with lower support. However, the power of indel gene trees became clear when we combined them with nt gene trees, including a striking result for UCEs. The individual UCE indel and nt ASTRAL trees were incongruent with each other and with the intron ASTRAL trees; however, the combined indel+nt ASTRAL tree was much more congruent with the intronic trees.
