Evolutionary epidemiology and the dynamics of adaptation.
The mean fitness of a population, often equal to its growth rate, measures its level of adaptation to particular environmental conditions. A better understanding of the evolution of mean fitness could thus provide a natural link between evolution and demography. Yet, after the seminal work of Fisher and its renowned "fundamental theorem of natural selection," the dynamics of mean fitness has at...
متن کاملstudy on some immunological responses of rainbow trout (onchorhynchus mykiss) to some antigens of streptococcus iniae
some specific and non-specific immune variables of rainbow trout were assessed following vaccination of fish with formalin killed cells (fkc) and fkc containing extra cellular products (ecp) of s. iniae. rainbow trout weighing 80-100 g were vaccinated by intraperitoneal (i.p), dip and oral routes using fkc and fkc plus ecp with or without fround adjuvant (fa) at 16-17°c.antibody titration, lyso...
متن کاملTowards Control of Streptococcus iniae
Streptococcus iniae is an emerging zoonotic pathogen; such infections generally occur through injuries associated with preparing whole fresh fish for cooking. Those infected to date have been of Asian descent, are usually elderly (average age 68 years), and have had >/=1 underlying conditions that may predispose them to infection. Studies of the foundations of growth characteristics of S. iniae...
متن کاملTemporal dynamics of shrub proliferation: linking patches to landscapes
Shifts in vegetation composition and cover are the result of processes acting at different levels such as landscapes, hill slopes, or plant interspaces. Analytical approaches designed for discrete objects which are based upon the inherently hierarchical nature of complex systems are well suited to research applications conducted across spatial scales. We quantified spatial and temporal vegetati...

pose potential health risks, particularly to young children. While California has reported more cases of baylisascariasis than any other state, few published studies have reported on the distribution and prevalence of this helminth in the region. In 2001, we conducted a study to determine the presence of B. procyonis in the Santa Barbara area by examining roadkill raccoons recovered by animal c...
