Inbreeding ratio and genetic relationships among strains of the Western clawed frog, Xenopus tropicalis [PDF]

open access: yes, 2015
The Western clawed frog, Xenopus tropicalis, is a highly promising model amphibian, especially in developmental and physiological research, and as a tool for understanding disease.

First Vasectomy Procedure Successfully Performed on a Southern African Male Giraffe (Giraffa camelopardalis giraffa)

open access: yesZoo Biology, EarlyView.
First successful vasectomy in a southern African male giraffe, Giraffa camelopardis giraffa ABSTRACT This study reports the first successful vasectomy on a southern African male giraffe (Giraffa camelopardalis giraffa). The goal of the procedure was to create a teaser male for reproductive studies.

Warm waters undermine cryptic female choice

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding the thermal sensitivity of reproductive interactions is crucial given global warming. Previous studies have almost exclusively focused on interactions before mating, even though important interactions between the sexes also occur after mating (e.g.

Opposition to Inbreeding Between Close Kin Reflects Inclusive Fitness Costs

open access: yesFrontiers in Psychology, 2018
Due to the intense selection pressure against inbreeding, humans are expected to possess psychological adaptations that regulate mate choice and avoid inbreeding. From a gene’s-eye perspective, there is little difference in the evolutionary costs between

Removing exogenous information using pedigree data

open access: yes, 2011
Management of certain populations requires the preservation of its pure genetic background. When, for different reasons, undesired alleles are introduced, the original genetic conformation must be recovered.

Biparental inbreeding depression, genetic relatedness and progeny vigor in a wind-pollinated treeline species in Argentina [PDF]

open access: yes, 2009
Spatially restricted gene flow and resulting spatial genetic structure are generally considered as being the primary controlling factors in the dynamics of biparental inbreeding depression in a wide range of plant species.

Trade‐offs across life history stages and social association types shape winter communal roosting in a long‐lived raptor

open access: yesJournal of Animal Ecology, EarlyView.
Our study demonstrates how life history trade‐offs and pair bonds influence winter roosting in red kites. Analysing long‐term GPS data from 216 individuals, we reveal marked behavioural plasticity in communal roosting: young, non‐breeding males are most likely to join communal roosts, whereas breeding pairs predominantly roost together near their ...

Optimizing mating schemes in fish breeding [PDF]

open access: yes, 2007
The optimal contribution selection method and the simulated annealing algorithm were used to maximize the genetic gain and reduce inbreeding in fish breeding populations.

Long‐term trends of epibionts reflect Mediterranean striped dolphin abundance shifts caused by morbillivirus epidemics

open access: yesJournal of Animal Ecology, EarlyView.
This original research piece demonstrates, through empirical and theoretical modelling approaches, that the epibionts of striped dolphins indicate dolphin abundance shifts caused by epidemics of dolphin morbillivirus (DMV). In addition, we provide the first SIR model to investigate the epidemiology of DMV in western Mediterranean striped dolphins ...

Multilocus sequence typing of the invasive pest Halyomorpha halys (Hemiptera: Pentatomidae) and associated endosymbiont reveals unexplored diversity

open access: yesInsect Science, EarlyView.
A multilocus sequence typing approach is proposed to explore Halymorpha halys genetic diversity, taking into consideration both insect nuclear markers and markers from the gut symbiont “Candidatus Pantoa carbekii.” Increased information was revealed regarding the number of distinct holobiont haplotypes in native and invasive populations of the pest ...
