Pathogen relatedness affects the prevalence of within-host competition.
Although the evolutionary consequences of within-host competition among pathogens have been examined extensively, there exists a critical gap in our understanding of factors determining the prevalence of multiple infections. Here we examine the effects of relatedness among strains of the anther-smut pathogen Microbotryum violaceum on the probability of multiple infection in its host, Silene lat...
متن کاملHost Sexual Dimorphism and Parasite Adaptation
In species with separate sexes, parasite prevalence and disease expression is often different between males and females. This effect has mainly been attributed to sex differences in host traits, such as immune response. Here, we make the case for how properties of the parasites themselves can also matter. Specifically, we suggest that differences between host sexes in many different traits, suc...
متن کاملMonomorphism, male-male competition, and mechanisms of sexual dimorphism.
Reconstructing sociosexual variables such as mating system and social organization from fragmentary fossils and other sources of data remains a major challenge in understanding the evolution of behavioral and morphological diversity within the primate order. Often, a particular mating system can lead to the evolution of novel behavior (e.g., ‘‘competitive’’ paternal care in tamarins; Garber, 19...
متن کاملSexual growth dimorphism affects birth sex ratio in house mice.
We present the first empirical evidence that mammalian sex-ratio deviations result from variation in adult-weight sexual dimorphism via correlated effects on blastocyst development. Two selection lines of mice exhibiting high and low sexual dimorphism in adult weight showed correlated sexual weight differences at birth and at weaning, caused by relatively decelerated growth of males in the low ...
متن کاملCompetition for zinc binding in the host-pathogen interaction
Due to its favorable chemical properties, zinc is used as a structural or catalytic cofactor in a very large number of proteins. Despite the apparent abundance of this metal in all cell types, the intracellular pool of loosely bound zinc ions available for biological exchanges is in the picomolar range and nearly all zinc is tightly bound to proteins. In addition, to limit bacterial growth, som...
