Population size and viability

Myocardial Viability and Remodeling: Does Size Matter?

I schemic heart disease with resultant left ventricular (LV) dysfunction is the major underlying cause of heart failure and carries significant morbidity and mortality. Therapeutic endeavors to improve the prognosis of these patients have evolved over the years and include a multifaceted approach aimed at alleviating symptoms and improving ventricular function, and reducing reinfarction and sud...

Review of Population Viability Analysis

Wildlife Tunnel Enhances Population Viability

Roads and traffic are pervasive components of landscapes throughout the world: they cause wildlife mortality, disrupt animal movements, and increase the risk of extinction. Expensive engineering solutions, such as overpasses and tunnels, are increasingly being adopted to mitigate these effects. Although some species readily use such structures, their success in preventing population extinction ...

language learning strategies and vocabulary size of iranian efl learners

learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...

Population viability analyses on a cycling population: a cautionary tale

Population viability analysis (PVA) packages do not always allow realistic simulation of particular life cycle features, so they may produce unrealistic predictions of extinction risk. This was suspected for a cycling Soay sheep population, Ovis aries L., that grows, overeats its habitat and then su€ers high winter mortality. We compared projections of PVA models for the sheep that incorporated...
