A Neonicotinoid Insecticide at a Rate Found in Nectar Reduces Longevity but Not Oogenesis in Monarch Butterflies, Danaus plexippus (L.). (Lepidoptera: Nymphalidae)

The monarch butterfly in North America has suffered a serious population decline since the mid-1990s.The introduction and widespread use of neonicotinoid insecticides during the same Speaker Harness time period has been suggested as a potential driver of this decline but no studies have looked at the impact of these insecticides on adult monarchs.A

Natural variation in life history and aging phenotypes is associated with mitochondrial DNA deletion frequency in Caenorhabditis briggsae

Abstract Background Mutations that impair mitochondrial functioning are associated with a variety of metabolic and age-related disorders.A barrier to rigorous tests of the role of mitochondrial dysfunction in aging processes has been the lack of model systems with relevant, naturally occurring mitochondrial genetic variation.Toward the goal of deve

Characterization of a strain-specific CD-1 reference genome reveals potential inter- and intra-strain functional variability

Abstract Background CD-1 is an outbred mouse stock that is frequently used in toxicology, pharmacology, and fundamental biomedical research.Although inbred strains are typically better suited for such studies due to minimal genetic variability, outbred stocks confer practical advantages over inbred strains, such as improved breeding performance and
