Mating system and role of pycnidiospores in biology of Polystigma amygdalinum, the causal agent of almond red leaf blotch

open access: yesPhytopathologia Mediterranea, 2016
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

open access: yesFrontiers in Ecology and Evolution, 2018
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

open access: yesBMC Plant Biology, 2019
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.

Correlates of genetic monogamy in socially monogamous mammals: insights from Azara's owl monkeys [PDF]

open access: yes, 2014
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.

Mating system drives negative associations between morphological features in Schistosomatidae

open access: yesBMC Evolutionary Biology, 2010
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 ...

On extending the Hardy-Weinberg law

open access: yesGenetics and Molecular Biology, 2007
This paper gives a general mating system for an autosomal locus with two alleles. The population reproduces in discrete and non-overlapping generations.

Reproductive biology of Piper species (Piperaceae): a review to link the past to the future [PDF]

open access: yesRodriguésia, 2023
Piper species are important components of the understory in tropical and subtropical forests, and some species are of economic and medicinal importance. This genus has been studied in different areas of science.

Incidence and post-pollination mechanisms of nonrandom mating in Arabidopsis thaliana [PDF]

open access: yes, 2009
Compatible pollinations from many differenttaxa display nonrandom mating. Here we describe a systemfor examining questions of nonrandom mating in Arabidopsisthaliana.

Life history and mating systems select for male biased parasitism mediated through natural selection and ecological feedbacks [PDF]

open access: yes, 2010
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.

Animal‐borne video systems provide insight into the reproductive behavior of the Asian black bear

open access: yesEcology and Evolution, 2021
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.
