Morning glory species co‐occurrence is associated with asymmetrically decreased and cascading reproductive isolation

Evolution Letters, 2021
Hybridization between species can affect the strength of the reproductive barriers that separate those species. Two extensions of this effect are (1) the expectation that asymmetric hybridization or gene flow will have asymmetric effects on reproductive ...

Experimental evidence of polyandry and prolonged copulations in Photinus palaciosi, a synchronous firefly with brachypterous females (Coleoptera: Lampyridae)

European Journal of Entomology, 2023
Males of some species of the firefly Photinus produce nutritious spermatophores (nuptial gifts) the production of which is associated with a specific reproductive morphology.

Local Coastal Configuration Rather Than Latitudinal Gradient Shape Clonal Diversity and Genetic Structure of Phymatolithon calcareum Maerl Beds in North European Atlantic

Frontiers in Marine Science, 2019
Maerl beds are one of the world’s key coastal ecosystems and are threatened by human activities and global change. In this study, the genetic diversity and structure of one of the major European maerl-forming species, Phymatolithon calcareum, was studied

Transient population dynamics of mosquitoes during sterile male releases : modelling mating behaviour and perturbations of life history parameters [PDF]

, 2013
The release of genetically-modified or sterile male mosquitoes offers a promising form of mosquito-transmitted pathogen control, but the insights derived from our understanding of male mosquito behaviour have not fully been incorporated into the design ...

Mating system of a population of Myracrodruon urundeuva F.F. & M.F. Allemão using the fAFLP molecular marker

Genetics and Molecular Biology, 2004
The mating system and genetic diversity were studied in a natural population of Myracrodruon urundeuva originating from 30 open-pollinated trees at the Paulo de Faria Ecological Station, SP, Brazil. The progenies were planted on the Teaching and Research

Could the reproductive system explain the stability and long-term persistence in a natural hybrid zone of Petunia (Solanaceae)?

Acta Botânica Brasílica, 2022
The long-term success of populations is dependent on individual reproductive success, and in general, increased population size and genetic diversity contribute to population maintenance, reducing the risk of local extinction. Interspecific hybridization

Female mating preferences in blind cave tetras Astyanax fasciatus (Characidae, Teleostei). [PDF]

, 2006
The Mexican tetra Astyanax fasciatus has evolved a variety of more or less color- and eyeless cave populations. Here we examined the evolution of the female preference for large male body size within different populations of this species, either surface-

The costs and benefits of multiple mating in a mostly monandrous wasp

, 2015
Funding: NERC DTGThe taxonomically widespread nature of polyandry remains a puzzle. Much of the empirical work regarding the costs and benefits of multiple mating to females has, for obvious reasons, relied on species that are already highly polyandrous.

Impact of mating systems on patterns of sequence polymorphism in flowering plants [PDF]

, 2006
A fundamental challenge in population genetics and molecular evolution is to understand the forces shaping the patterns of genetic diversity within and among species.

Reproductive strategies and population genetic structure of Fucus spp. across a northeast Atlantic biogeographic transition☆

Aquatic Living Resources, 2017
Geographical discontinuities in the composition of species assemblages are often mirrored by genetic clines and local adaptation in species that extend across such biogeographic disjunction.
