Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

open access: yesInsect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

Inbreeding affects the survival of Danish Jersey and Holstein dairy cows

open access: yesJournal of Dairy Science
: This study evaluated the effects of pedigree and genomic inbreeding on survival in Danish Jersey (JER) and Danish Holstein (HOL) dairy cows. Survival probabilities and hazard risks (HR) were estimated using Kaplan–Meier analysis and Cox proportional ...

open access: yes, 2005
Thesis (M.S.) University of Alaska Fairbanks, 2005Different populations of a species distributed over diverse conditions adapt to their local environments to improve their ability to survive or reproduce. Intraspecific hybridization can alter the locally

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

open access: yesInsect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Genetic Diversity, Inbreeding Level, and Genetic Load in Endangered Snub-Nosed Monkeys (Rhinopithecus)

open access: yesFrontiers in Genetics, 2020
The snub-nosed monkey genus (Rhinopithecus) comprises five closely related species (R. avunculus, R. bieti, R. brelichi, R. roxellana, and R. strykeri). All are among the world's rarest and most endangered primates. However, the genomic impact associated

Population stratification and genetic association studies in South Asia [PDF]

open access: yes, 2005
Population stratification and its influence on genetic association studies is a controversial topic. Although it has been suggested that stratification is unlikely to bias the results of association studies conducted in developed countries, convincing ...

The shibirets4 mutation causes temperature sensitive paralytic and lethal phenotypes in the Queensland fruit fly, Bactrocera tryoni

open access: yesInsect Science, EarlyView.
Abstract Bactrocera tryoni, the Queensland fruit fly, is among the most damaging insect pests to the Australian horticultural industry as larvae infest ripening fruits or vegetables prior to harvest. Genetic biocontrol using Sterile Insect Technique (SIT) programs have been used to successfully suppress populations, via mass release of factory‐reared ...

Development and characterization of tri- and tetra-nucleotide polymorphic microsatellite markers for skipjack tuna (Katsuwonus pelamis) [PDF]

open access: yes, 2012
Skipjack tuna (katsuwonus pelamis) (SJT) is the largest tuna fishery in all the major oceans around the world, and the largest marine fishery in Sri Lanka. Knowledge of genetic population structure and effective population size of SJT in the Indian Ocean

Sequence and expression analysis of potential spermatogenesis‐specific gene cognates in the Caribbean fruit fly, Anastrepha suspensa

open access: yesInsect Science, EarlyView.
Abstract The sterile insect technique (SIT) is a highly effective biologically‐based method for the suppression of many insect pest populations. SIT efficacy could be improved by methods of male sterilization that avoid the use of irradiation that can result in diminished fitness and mating competitiveness.
