Multidirectional chromosome painting substantiates the occurrence of extensive genomic reshuffling within Accipitriformes. [PDF]

open access: yes, 2015
BACKGROUND: Previous cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1-10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive ...

Habitat use and reproductive success of ospreys in central interior California

open access: yesCalifornia Fish and Wildlife Journal, 2022
The osprey (Pandion halieatus) declined globally in the mid-late 20th century due primarily to pesticide contamination that reduced reproduction. The species has recovered through much of its range, and its range in California has increased.
