  1. Taxonomic and phylogenetic utility of variation in advertising calls of francolins and spurfowls (Galliformes: Phasianidae)

    Taxonomic and phylogenetic utility of variation in advertising calls of francolins and spurfowls (Galliformes: Phasianidae)

    Item type: Journal Article • Journal: African Zoology • Authors: Tshifhiwa G. Mandiwana-Neudani --- Department of Biodiversity, South Africa Rauri C. K. Bowie --- Department of Biological Sciences, South Africa Martine Hausberger --- Université de Rennes 1, France Laurence Henry --- Université de Rennes 1, France Timothy M. Crowe --- Department of Biological Sciences, South Africa
    Systematists have not often made use of avian vocalizations to assess the taxonomic rank of birds, or to infer their phylogenetic relationships. The likely reasons for this stem from the perceived inability to distinguish genetic and ecological components of variation...

  2. Behavioural responses to air temperature change in helmeted guineafowl <em>Numida meleagris</em>

    Behavioural responses to air temperature change in helmeted guineafowl Numida meleagris

    Item type: Journal Article • Journal: African Zoology • Authors: Johann H van Niekerk --- University of South Africa, South Africa Marta Rodríguez-Rey --- Universidad de Alcalá, Forest Ecology and Restoration Research Group (FORECO), Spain Fabián Casas --- Universidad de Granada, Spain Giovanni Forcina --- Global Change Ecology and Evolution Research Group (GloCEE)/Soil Biology and Subterranean Ecosystems Research Group (GIBSES), Spain
    Deciphering the behavioural responses of helmeted guineafowl Numida meleagris (Linnaeus, 1758) to temperature variation is key to understanding its eco-ethology and implementing sound management strategies. Here, we tested the ‘warmer together’ hypothesis, which states that thermoregulatory cost reduction (i.e. body...
