Variation in sexual dimorphism and assortative mating do not predict genetic divergence in the sexually dimorphic Goodeid fish Girardinichthys multiradiatus

Current Zoology, 2012
Sexual dimorphism is often used as a proxy for the intensity of sexual selection in comparative studies of sexual selection and diversification. The Mexican Goodeinae are a group of livebearing freshwater fishes with large variation between species in ...

Genetic Parameters and Sex‐Specific Architecture of Observed and Latent Fertility Phenotypes in a Closed Breeding Nucleus of an Arctic Salmonid

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Successful reproduction is a key factor for efficient breeding schemes and sustainable animal farming. Aquaculture breeding programs rely heavily on small fractions of selected breeders to yield large production stocks, given the high fecundity typically observed in these species. In Sweden, Arctic charr (Salvelinus alpinus) is a salmonid with

Do olive ridley turtles select mates based on size? An investigation of mate size preference at a major arribada rookery

Ecosphere
We investigated mate size preferences in olive ridley sea turtles (Lepidochelys olivacea), one of the world's smallest and most abundant sea turtle species, using data from two years near a single mass nesting site.

Multivariate maternal effects across the internalizing–externalizing spectrum in childhood: results from the Norwegian mother, father, and child cohort study

Journal of Child Psychology and Psychiatry, EarlyView.
Background From a functionalist perspective, parenting behaviors have adaptive functions and are partly expressions of genetic variation. Maternal genes that have effects on children are often referred to as indirect maternal genetic effects. Indirect genetic effects provide a means for measuring the role of parenting without the need for specifying ...

Daily Rhythms of Sex Pheromone Emission and Courtship Behaviour in the Neotropical Brown Stink Bug Euschistus heros

Journal of Applied Entomology, EarlyView.
ABSTRACT Understanding the chemical and behavioural ecology of the Neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), is essential for developing effective integrated pest management (IPM) strategies in South American soybean production. This study investigated the courtship behaviour and diel periodicity of sex pheromone emission.

Male‐territory‐visiting polygamy in the sand‐dwelling goby Fusigobius inframaculatus (Gobiidae) inhabiting reef caves

Journal of Fish Biology, EarlyView.
Abstract We conducted an observational field survey of the innerspotted sandgoby Fusigobius inframaculatus on reefs of Kuchierabu‐jima Island, southern Japan, to investigate its mating system. Individuals of the goby maintained home ranges on sandy bottoms within rocky caves or beneath overhangs that served as shelters. Of 34 identified individuals, 32%

When biology meets materials science – Interdisciplinary applications of electron microscopy

Journal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

Journal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

The Effects of Assortative Mating on Earnings: Human Capital Spillover or Specialization? [PDF]

This paper studies how the spouse’s productivity in the labor market affects one’s individual earnings when married. Theoretically, the high productivity of a spouse in a marriage could affect the other spouse’s earnings in two ways: negatively through ...
