TL;DR: A universal multimarker assay for reliable sex identification of three‐spined sticklebacks (Gasterosteus aculeatus) makes use of genotype scores from three sex‐linked loci and utilizes Bayesian probabilistic inference to identify sex of the genotyped individuals.

TL;DR: In a common garden experiment conducted with three‐spined sticklebacks originating from four different populations, no evidence for a positive effect of environmental enrichment on brain size or size of different brain parts in either of the sexes in any of the populations is found.

TL;DR: The findings support the notion that the stickleback brain is highly plastic and changes over the breeding cycle, especially in males, likely as an adaptive response to the cognitive demands of reproduction (e.g. nest construction and parental care).

TL;DR: The results show that mosquitofish introductions, particularly in areas with populations exhibiting paedomorphosis, might have detrimental consequences on the preservation of alternative developmental pathways, and both behavioral and phenotypic effects should be assessed to understand the impacts of introduced species.

TL;DR: Based on the single nucleotide polymorphisms obtained, candidate loci putatively associated with the alternative morphs that mapped to four genes have functional roles in metabolic processes that may mediate the persistence of alternative ontogenetic trajectories.
