Predation shapes sperm performance surfaces in guppies [PDF]
Sperm velocity is a key determinant of competitive fertilization success in many species. Selection is therefore expected to favour the evolution of faster sperm when the level of sperm competition is high. However, several aspects can determine the direction and strength of selection acting on this key performance trait, including ...

Abstract Intensive multigenerational size‐selective mortality has been found to alter collective properties like shoaling via evolutionary adaptations of individual‐level behavioural traits. For example, experimental populations of zebrafish (Danio rerio) experiencing intensive large size‐selective mortality over multiple generations developed less ...

Family names as indicators of Britain’s changing regional geography [PDF]
In recent years the geography of surnames has become increasingly researched in genetics, epidemiology, linguistics and geography. Surnames provide a useful data source for the analysis of population structure, migrations, genetic relationships and ...

Evaluation of Experimental Populations and Glandular-Haired Varieties of Alfalfa for Alfalfa Blotch Leafminer (Diptera: Agromyzidae) Feeding Injury [PDF]
Following the spread of the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae), into Minnesota and Wisconsin U.S.A. during 1994-1997, three field trials were conducted in Minnesota to assess the potential for leafminer ...

Bony fish genomes: Status and gaps
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Convergent evolution of coloration in experimental introductions of the guppy (Poecilia reticulata). [PDF]
Despite the multitude of examples of evolution in action, relatively fewer studies have taken a replicated approach to understand the repeatability of evolution.

Sexual selection and reproductive success in mesocosm populations of African annual killifish
Abstract Variation in individuals’ ability to obtain mates generates sexual selection, which typically acts more strongly on males and can produce pronounced differences in phenotypes between the sexes (i.e., sexual dimorphism). The dynamic of sexual selection and individual reproductive success is considerably affected by the availability of ...

Soil phosphorus status in organic and conventional vegetable farms in Southeast Queensland, Australia [PDF]
The soil phosphorus (P) status (0-10 cm) of two farming systems (organic (OF) and conventional (CF) vegetable farms) at two locations (Gatton and Stanthorpe) was examined amongst a suite of soil fertility indicators.
