  • A Molecular Phylogeny of Anseriformes Based on Mitochondrial DNA Analysis
    MOLECULAR PHYLOGENETICS AND EVOLUTION Molecular Phylogenetics and Evolution 23 (2002) 339–356 www.academicpress.com A molecular phylogeny of anseriformes based on mitochondrial DNA analysis Carole Donne-Goussee,a Vincent Laudet,b and Catherine Haanni€ a,* a CNRS UMR 5534, Centre de Genetique Moleculaire et Cellulaire, Universite Claude Bernard Lyon 1, 16 rue Raphael Dubois, Ba^t. Mendel, 69622 Villeurbanne Cedex, France b CNRS UMR 5665, Laboratoire de Biologie Moleculaire et Cellulaire, Ecole Normale Superieure de Lyon, 45 Allee d’Italie, 69364 Lyon Cedex 07, France Received 5 June 2001; received in revised form 4 December 2001 Abstract To study the phylogenetic relationships among Anseriformes, sequences for the complete mitochondrial control region (CR) were determined from 45 waterfowl representing 24 genera, i.e., half of the existing genera. To confirm the results based on CR analysis we also analyzed representative species based on two mitochondrial protein-coding genes, cytochrome b (cytb) and NADH dehydrogenase subunit 2 (ND2). These data allowed us to construct a robust phylogeny of the Anseriformes and to compare it with existing phylogenies based on morphological or molecular data. Chauna and Dendrocygna were identified as early offshoots of the Anseriformes. All the remaining taxa fell into two clades that correspond to the two subfamilies Anatinae and Anserinae. Within Anserinae Branta and Anser cluster together, whereas Coscoroba, Cygnus, and Cereopsis form a relatively weak clade with Cygnus diverging first. Five clades are clearly recognizable among Anatinae: (i) the Anatini with Anas and Lophonetta; (ii) the Aythyini with Aythya and Netta; (iii) the Cairinini with Cairina and Aix; (iv) the Mergini with Mergus, Bucephala, Melanitta, Callonetta, So- materia, and Clangula, and (v) the Tadornini with Tadorna, Chloephaga, and Alopochen.

Although there is no crescent of color on the upper-tail coverts and the wings do not produce special sounds in flight, the upper surface of the wing does flash a brilliant white when the bird is flying. The species occurs from the southern tip of the United States through most of South America, and two subspecies are recognized. It is broadly sympatric with the fulvous and the white- faced whistling duck, and possibly also with the Cuban. Hybrids with all these species have been obtained in captivity. General behavior. The red-billed whistling duck is a highly vocal and noisy bird, and its usual call is more musical than that of any other whistling duck. The call consists of from five to seven notes, and can be written as whech, wha-cW-whe-whewhew or whech, wha-chew-whew-whew'.

  • Tracheal Anatomy of the Anatidae and Its Taxonomic Significance
    TRACHEAL ANATOMY OF THE ANATIDAE AND ITS TAXONOMIC SIGNIFICANCE Paul A. Johnsgard Summary T r a c h ea l and syringeal variations in waterfowl are summarized, based on a tracheal collection representing 84 out of the 143 species of Anatidae. Twenty seven species are illustrated with drawings, and photographs of 24 species are also included, comprising 29 of the 43 genera of Anatidae. The following major points are made : 1. The Magpie Goose (Anseranas semipalmata) is unique in its externally convoluted trachea, but the syrinx is small and simple in both sexes. 2. Species of the subfamily Anserinae have symmetrical tracheae in both sexes, which either lack bullae (Anserini) or have symmetrical bullae which are larger in males than in females (Dendrocygnini). 3. The Coscoroba Swan (Coscoroba coscoroba) and the Cereopsis Goose (Cereopsis novae­ hollandiae) have tracheae of the Anserini type, and the Freckled Duck (Stictonetta naevosa) has an extremely simple and primitive type of trachea and syrinx in both sexes. 4. Species of the subfamily Anatinae exhibit sexual dimorphism in the syrinx, and males of most species except stiff-tails (Oxyurini) possess asymmetrically enlarged syrinxes (bullae). 5. Enlargements of the tracheal tubes of male Anatinae occur in a few dabbling ducks (Anatini), most of the pochards (Aythyini) and most sea ducks (Mergini). Tracheal air sacs occur in some stiff-tails, and extra-tracheal sound production is also typical of this group. 6. Although males of most Anatinae possess entirely osseous bullae, partially membranaceous (fenestrated) bullae are found in all pochards and most sea ducks. The Marbled Teal (Marmaronetta angustirostris) and Pink-headed Duck (Rhodonessa caryophyllacea) also possess fenestrated bullae which are intermediate between the dabbling duck and pochard types.
