Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Host associations, biogeography, and phylogenetics of avian malaria in southern African waterfowl [PDF]

, 2012
The relevance of spatial variation in the environment and host communities for parasite community composition is poorly documented, creating a need for additional case studies from which general principles can be developed.

The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Aspects of the biology of the little shag (Phalacrocorax melanoleucos brevirostris Veillot 1817) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]

, 1984
Aspects of the biology of the little shag (Phalacrocorax melanoleucos brevirostris Veillot) were examined from December 1980 until April 1983 at Hamilton's and Sexton's Lagoons in lowland Manawatu. Body measurements and plumage patterns of both sexes are

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

Journal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

The genome sequence of the European shag, Gulosus aristotelis (previously Phalacrocorax aristotelis) (Linnaeus, 1761) [version 2; peer review: 1 approved, 2 approved with reservations]

Wellcome Open Research
We present a genome assembly from an individual female Gulosus aristotelis, previously known as Phalacrocorax aristotelis, (the European shag; Chordata; Aves; Pelecaniformes; Phalacrocoracidae). The genome sequence is 1,279.1 megabases in length. Most of
