Why rotation and mixture fail: treatment history and the declining acaricide efficacy in Varroa destructor

open access: yesPest Management Science, EarlyView.
The effect of IRM strategies (rotation, mixture), one additional year under acaricide treatment (Years treated (+1 year)), and one year without acaricide treatment (Years off treatment (+1 year) on mite mortality relative to an approximately 17% baseline.

Management of Genetic Diversity in the Era of Genomics

open access: yesFrontiers in Genetics, 2020
Management of genetic diversity aims to (i) maintain heterozygosity, which ameliorates inbreeding depression and loss of genetic variation at loci that may become of importance in the future; and (ii) avoid genetic drift, which prevents deleterious ...

Impact of Environmental Microparticles on Insect Olfaction

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Why wolves walk – drivers of daily movement in a social large carnivore

open access: yesWildlife Biology, EarlyView.
Animal movement patterns are influenced by a range of extrinsic and intrinsic factors, including the distribution of resources, human disturbance, landscape connectivity, species interactions, and individual traits. We examined factors associated with daily movement distance (DMD) and linearity in 20 territorial Scandinavian wolves Canis lupus during ...

Minimizing inbreeding by managing genetic contributions across generations [PDF]

open access: yes, 2003
Here we present the strategy that achieves the lowest possible rate of inbreeding (DeltaF) for a population with unequal members of sires and dams with random mating. This new strategy results in a DeltaF as much as 10% lower than previously achieved.

Evolution of precopulatory and post-copulatory strategies of inbreeding avoidance and associated polyandry [PDF]

open access: yes, 2017
Inbreeding depression is widely hypothesised to drive adaptive evolution of pre-copulatory and post-copulatory mechanisms of inbreeding avoidance, which in turn are hypothesised to affect evolution of polyandry (i.e., female multiple mating).

Assessing genetic diversity in a reintroduced Mediterranean griffon vulture Gyps fulvus population to inform long‐term conservation management

open access: yesWildlife Biology, EarlyView.
Reintroductions play a key role in conservation biology. Their long‐term success strongly depends on maximizing the genetic diversity of founders, as well as on ensuring ecological connectivity with adjacent populations. Accordingly, evaluating the conservation status of reintroduced populations to limit the loss of their genetic diversity requires ...

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

Impact of nonadditive genetic effects in the estimation of breeding values for fertility and correlated traits [PDF]

open access: yes, 2005
The effects of inbreeding, heterosis, recombination loss, and percentage Holstein on the estimation of predicted transmitting abilities for fertility traits (calving interval, number of days from calving to first insemination, nonreturn rate, number of ...

Biology, ecology, and conservation of the Italian hare Lepus corsicanus: a review

open access: yesWildlife Biology, EarlyView.
The Italian hare Lepus corsicanus, an endemic lagomorph of Italy, serves as a critical case study in evolutionary biology and conservation. Once taxonomically debated, modern genetic and morphological analyses confirm its status as a distinct Pleistocene lineage restricted to the central‐southern Italian Peninsula and Sicily.
