Embryotoxicity of the oil dispersant Corexit 9500 was examined using fertilized mallard duck eggs. Corexit 9500 was topically applied below the air cell to eggs in volumes ranging from 0 to 100 μL on day 3 of incubation. The highest incidence of mortality occurred at developmental stage 4, one day post-Corexit 9500 application. Hatching success was significantly decreased among eggs treated wit...

General Equilibrium models of Land-Use and Transport (to which we will hereafter refer to as GELUT), as conceived and developed in the contributions of Anas and Kim (1996), Anas and Xu, (1997), Anas and Liu (2007) and applied empirically by Anas and Hiramatsu (2012; 2013) are becoming established as a widely accepted framework to model the urban economic environment. The approach provides a con...

The ecology of avian influenza (AI) viruses in wild aquatic birds of Asia is poorly understood, especially for the H5N1 high pathogenicity AI (HPAI) viruses. From March 2006 through November 2008, 20 AI viruses were isolated in the Crimea region of Ukraine with an overall frequency of virus recovery of 3.3%. All the viruses were isolated from three species of dabbling ducks: mallard (Anas platy...

OBJECTIVE To test the postulate that there is a higher prevalence of antinuclear antibodies (ANAs) in serum samples from blood relatives and from spouses of patients with scleroderma than in control samples, and that this provides evidence for both genetic and environmental factors influencing autoimmunity in scleroderma. METHOD Testing for ANAs was performed on 58 patients with scleroderma, ...

The fatty acid compositions of yolk lipids of eggs collected in the wild from ®ve species of ducks (Anatidae) showing a range of dietary preferences, the king eider Somateria spectabilis, the lesser scaup Aythya af®nis, the mallard Anas platyrhynchos, the green-winged teal Anas crecca and the gadwall Anas streperi, are reported. For all ®ve species, the fatty acid pro®les conformed to a similar...

Highly pathogenic avian influenza (H5N8) virus, like the recently described H5N8 strain from Korea, was detected in November 2014 in farmed turkeys and in a healthy common teal (Anas crecca) in northeastern Germany. Infected wild birds possibly introduced this virus.

The Altiplano-Puna ultralow-velocity zone in the central Andes, South America, is the largest active magma body in Earth's continental crust. Space geodetic observations reported an uplift in the Altiplano-Puna proper at a rate of ~10 mm/year; however, the nature of the inferred inflation source has been uncertain. We present data showing that the uplift has persisted at a nearly constant rate ...

Paul Merola of the Connecticut DJLP. for allowing access to hunter-killed ducks. Many thanks to Beth Wingate-Ehrhorn for help with everything.

The outbreak of Riemerella anatipestifer (RA) infection has been confirmed in meat-type domestic ducks (Anas platyrhynchos) for the first time in 27 years in Japan. In January 2014, increased mortality in a 14- to 21-day-old duck flock was reported to veterinary officials by the owner. The affected ducks exhibited reduced movement, ataxia and dorsal recumbency with leg paddling. Pathological fi...
