and abandonment is causing considerable woodland expansion in many mountainous areas of Europe, with potential repercussions on conservation-sensitive species typical of open habitats. We examined the potential impact of such changes on an alpine golden eagle population, by estimating the ranges potentially used by the eagles for foraging through different techniques (concentric circles of diff...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013202300 DESCRIPTION The occurrence of talon cusp in the deciduous dentition is very rare. Aetiology for the formation of the talon cusp is unknown. However, it may be due to the combination of genetic and environmental factors and hyperactivity of the dental lamina e...

Background: Talon cusp is a supernumerary structure projecting from the dento-enamel junction to a variable distance towards the incisal edge of an anterior tooth. Studies have shown that it consists of enamel, dentine and a variable amount of pulp tissue. Hyperactivity of the enamel organ during morphodifferentiation has been attributed to its formation. Most previous reports have been made co...

Bald eagles and red-necked grebes were monitored from 2000 2002 on several lakes along the Pinchi fault, an area with a known source of geologic mercury and previous Hg mining (on Pinchi Lake), in an effort to discern whether increased Hg concentrations were affecting reproductive success and productivity. To determine whether or not Hg levels were elevated, fish tissues (rainbow trout and nort...

Polyhalogenated aromatic hydrocarbons are global contaminants that are often considered to be endocrine disruptors and include 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene (p,p'-DDE), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). The present study examined these compounds and their hydroxylated metabolites or analogues and relationships with circulating thyroid h...

In a recent number of this Journal, Bulmer, Eagles, and Hunter’ have published a study of the direct determination of uric acid in the blood as proposed by the present writer,2 in which the conclusion is reached that figures obtained by the direct method are “unreliable.” We feel that a few words of comment upon that paper may be of service in connection with the still unsettled question of the...

Introduction With the launch of the census of New France in 1666, Intendant of Justice, Police and Finance Jean Talon began the statistic taking tradition in Canada. The Intendant personally enumerated the 3,215 inhabitants of New France with regards to their age, sex, marital status and occupation. Interested in the characteristics of the inhabitants under his control, the information gathered...

Sternal dehiscence is a recognised complication after median sternotomy, occurring in 0.5-5% of cases with or without infection. A 72-year-old man presenting with collapse and ventricular tachycardia was investigated for a possible acute cardiac event 2 years after coronary artery bypass grafting for ischemic heart disease. Work-up chest X-ray showed displacement of all sternal wires, and compu...

A characteristic length scale, a∗ characterizing the flow is introduced in order to disting...

As urban and wild lands come into increasingly closer contact and as demands on wildlife and other natural resources increase, effective and sound ecological management of these resources becomes more critical. This is particularly true in Southeast Alaska where timber harvesting and coastal development continue to threaten Bald Eagle (Haliaeetus leucocephalus) populations. No longer can we sim...
