Svalbard rock ptarmigan: a first glimpse into parasite infections

Polar Research
Natural ecosystems are under stress due to climate change and impacts are especially prominent at high latitudes. Manifestations of these changes include northward shifts in the distribution of birds, phenological mismatches, improved survival of ...

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

The Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Intensive trapping of blood-fed Anopheles darlingi in Amazonian Peru reveals unexpectedly high proportions of avian blood-meals. [PDF]

PLoS Neglected Tropical Diseases, 2017
Anopheles darlingi, the main malaria vector in the Neotropics, has been considered to be highly anthropophilic. However, many behavioral aspects of this species remain unknown, such as the range of blood-meal sources. Barrier screens were used to collect

The protozoan parasite Trichomonas gallinae causes adult and nestling mortality in a declining population of European Turtle Doves, Streptopelia turtur [PDF]

, 2015
Studies incorporating the ecology of clinical and sub-clinical disease in wild populations of conservation concern are rare. Here we examine sub-clinical infection by Trichomonas gallinae in a declining population of free-living European Turtle Doves and

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

The Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Haptoglobins In Some Galliformes Birds

Poultry Science, 1977
In several groups of galliform birds (chicken, turkey, pheasant and guinea fowl) the presence and function of plasma haptoglobin (Hp) have been studied. Paper, acetate and starch-gel electrophoresis were carried out and two benzidine stain regions were observed when haemoglobin (Hb) was added to normal plasma (Hb-Hp complex and methemalbumin) besides ...

Suprageneric relationships of galliform birds (Aves, Galliformes): a cladistic analysis of morphological characters [PDF]

Zoological Journal of the Linnean Society, 2003
Of the basal clades of extant birds (Neornithes) the ‘landfowl’ or galliforms (Aves, Galliformes) are the most speciose. Cladistic analysis of more than 100 morphological characters coded at the generic level for most putative galliform genera confirms that the megapodes (‘mound builders’; Megapodiidae) are the most basal clade within the order.
