Immunity and Virulence in Bird-Parasite Interactions
The interaction between hosts and parasites is characterized by the evolution of reciproca adaptations aiming at reducing the cost of infection (from the host point of view) and to optimize host exploitation (from the parasite point of view). Within this co-evolutionary scenario, the immune system takes a central role. The immune system has evolved to fight off parasitic attacks. However, immun...
متن کاملHeritable variation in maternal yolk hormone transfer in a wild bird population.
Differential reproductive investment by the mother can critically influence offspring development and phenotype, and strong selection is therefore expected to act on such maternal effects. Although a genetic basis is a prerequisite for phenotypic traits to respond to selection and thus to evolve, we still know very little about the extent of heritable variation in maternal effects in natural po...
متن کاملNatural Parasite Infection Affects the Tolerance but Not the Response to a Simulated Secondary Parasite Infection
Parasites deplete the resources of their host and can consequently affect the investment in competing traits (e.g. reproduction and immune defence). The immunocompetence handicap hypothesis posits that testosterone (T) mediates trade-offs between parasite defence and reproductive investment by suppressing immune function in male vertebrates while more recently a role for glucocorticoids (e.g. c...
متن کاملMass Investigation on Intestinal Parasite Infection in Masjed Soleyman, Iran, 2010-2017: A Large Population Survey
Background and Aims: Globally, intestinal parasitic infections are a significant risk to human health. These infections may cause many health problems for humans, such as reduced growth, especially in children. This study, epidemiologically, aims to investigate the prevalence of intestinal parasitic infections which are collected from three medical centers in the city of Masjed Soleyman located...
متن کاملInteractions between prenatal maternal effects and posthatching conditions in a wild bird population
Resources and cues provided by the mother before birth are important mediators of developmental plasticity. It has been suggested that the adaptive value of such prenatal maternal effects may depend on the environment encountered by the offspring after birth, and that offspring may perform better when environmental conditions encountered by the mother and the offspring match, than when a mismat...
