| anticoagulant rodenticide exposure in an australian predatory bird increases with proximity to developed habitat. | anticoagulant rodenticides (ars) are commonly used worldwide to control commensal rodents. second generation anticoagulant rodenticides (sgars) are highly persistent and have the potential to cause secondary poisoning in wildlife. to date no comprehensive assessment has been conducted on ar residues in australian wildlife. my aim was to measure ar exposure in a common widespread owl species, the southern boobook (ninox boobook) using boobooks found dead or moribund in order to assess the spatial ... | 2018 | 29936157 |
| error rate of axons at the owl's optic chiasm. | in owls, the visual pathways from the retina are totally crossed. attempts to find ganglion cells with uncrossed axons have failed consistently, when retrograde labeling with hrp is used for their identification. in the present investigation we have used retrograde fluorescent tracers of complementary colour in each optic tectum to demonstrate a tiny population of ipsilaterally-projecting retinal ganglion cells in the owl. | 2004 | 15040775 |
| avian trichomoniasis: a study of lesions and relative prevalence in a variety of captive and free-living bird species as seen in an australian avian practice. | studies of avian trichomoniasis in the literature are limited to some extent, often being confined to a single bird species or group of species within a bird order. some incidence studies have been reported for free-living birds, and occasionally for captive birds. very few reports describe the prevalence and types of lesions seen for a wide range of bird species, especially from a clinical perspective. | 2011 | 21323655 |
| bioacoustic and multi-locus dna data of ninox owls support high incidence of extinction and recolonisation on small, low-lying islands across wallacea. | known for their rich biodiversity and high level of endemism, the islands of wallacea serve as natural laboratories for the study of spatio-temporal evolution and patterns of species diversification. our study focuses on the owl genus ninox, particularly the southern boobook (n. novaeseelandiae) and moluccan boobook (n. squamipila) complexes, which are widely distributed across australasia. we conducted bioacoustic and multi-locus dna analyses of 24 ninox owl taxa to evaluate relationships and l ... | 2017 | 28017857 |
