Between the early 1900s and the 1990s, the greater snow goose Anser caerulescens atlanticus population grew from 3000 individuals to more than 700 000. Because of concerns about Arctic degradation of natural habitats through overgrazing, a working group recommended the stabilization of the population. Declared overabundant in 1998, special management(More)
During its spring and fall migrations, the Greater Snow Goose (Chen caerulescens atlanticus) stages in the marshes along the St. Lawrence Estuary in southern Quebec, where it feeds on three-square bulrush (Schoenoplectus americanus) rhizomes. The goose population has grown from 70 000 birds to around one million over the last 40 years, thus increasing(More)
Infertile men have poorer sperm DNA integrity than do fertile men, and this damage may contribute to reducing male reproductive potential. However, the etiology of this damage has not been fully characterized. We sought to examine the relationship, if any, between anti-sperm antibodies and sperm DNA damage in a consecutive series of non-azoospermic,(More)
Spinal hamartomas are rare lesions consisting of disorganized ecto- and mesodermal tissues of the spinal region. While postnatal identification of spinal hamartomas has been reported, a literature search did not reveal any published reports of prenatal identification of spinal hamartomas. Here we report a 46,XX fetus who presented at 20 weeks' gestation(More)
Seminal antisperm antibodies (ASAs) have been associated with male infertility and a reduced probability of achieving a spontaneous pregnancy. However, the impact of ASAs on reproductive outcomes after assisted reproductive technologies (ARTs) remains controversial. We sought to further examine the relationship between ASAs and reproductive outcomes after(More)
