Polystigma amygdalinum is a serious leaf pathogen of almonds. Ascospores are believed to be the only inoculum of this pathogen. Ascocarp initials develop in infected leaves in contact with, or in close proximity to, filimentous spore-bearing bodies ...

Plant Mating Systems Often Vary Widely Among Populations
Most flowering plants are hermaphroditic, yet the proportion of seeds fertilized by self and outcross pollen varies widely among species, ranging from predominant self-fertilization to exclusive outcrossing.

Mixed mating system and variable mating patterns in tropical woody bamboos
Background So far, little is known in detail about mating systems of woody bamboos. Paternity analysis of offspring improved our understanding of these systems, and contributed to their germplasm conservation and genetic improvement.

Mating system drives negative associations between morphological features in
Background Sexual morphological features are known to be associated with the mating systems of several animal groups. However, it has been suggested that morphological features other than sexual characteristics could also be constrained by the mating ...

Correlates of genetic monogamy in socially monogamous mammals: insights from Azara's owl monkeys [PDF]
Understanding the evolution of mating systems, a central topic in evolutionary biology for more than 50 years, requires examining the genetic consequences of mating and the relationships between social systems and mating systems.

On extending the Hardy-Weinberg law
This paper gives a general mating system for an autosomal locus with two alleles. The population reproduces in discrete and non-overlapping generations.

Life history and mating systems select for male biased parasitism mediated through natural selection and ecological feedbacks [PDF]
Males are often the "sicker" sex with male biased parasitism found in a taxonomically diverse range of species. There is considerable interest in the processes that could underlie the evolution of sex-biased parasitism.

Gene-Mating Dynamic Evolution Theory II: Global stability of N-gender-mating polyploid systems
Extending the previous 2-gender dioecious diploid gene-mating evolution model [arXiv:1410.3456], we attempt to answer "whether the Hardy-Weinberg global stability and the exact analytic dynamical solutions can be found in the generalized N-gender N ...

Animal‐borne video systems provide insight into the reproductive behavior of the Asian black bear
Previous studies on the mating system of the Asian black bear (Ursus thibetanus) have been limited to observations of captive populations and estimations of multiple paternities. Hence, the mating system of wild bears remains poorly understood.
