Expression profiles of urbilaterian genes uniquely shared between honey bee and vertebrates

BMC Genomics, 2009
Background Large-scale comparison of metazoan genomes has revealed that a significant fraction of genes of the last common ancestor of Bilateria (Urbilateria) is lost in each animal lineage.

When African and European Lineages Meet: The Genetic Landscape of Honey Bees in Argentina

Ecology and Evolution
ABSTRACT Argentina has a complex and diverse landscape of honeybee ( Apis mellifera sp.) populations shaped by historic introductions and hybridization between Africanized (AHB) and European (EHB) lineages.

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Lineage and Parent-of-Origin Effects in DNA Methylation of Honey Bees (Apis mellifera) Revealed by Reciprocal Crosses and Whole-Genome Bisulfite Sequencing

Genome Biology and Evolution, 2020
AbstractParent-of-origin methylation arises when the methylation patterns of a particular allele are dependent on the parent it was inherited from. Previous work in honey bees has shown evidence of parent-of-origin-specific expression, yet the mechanisms regulating such pattern remain unknown in honey bees.

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

Entomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Noah's Raven, Noah's Son: The Metamorphoses of Blackness in Early Modern Readings of Genesis 8‐9

Renaissance Studies, EarlyView.
ABSTRACT Over the past half‐century, scholars have offered various theories to explain when and how an aetiology for black skin became part of the reception history of the so‐called Curse of Ham in Genesis 9—a text that does not include any reference to skin colour.

Mitochondrial genome of the North African Sahara Honeybee, Apis mellifera sahariensis (Hymenoptera: Apidae)

Mitochondrial DNA. Part B. Resources, 2017
We present the complete mitochondrial genome of honey bee subspecies, Apis mellifera sahariensis (Apidae) belonging to the African lineage. The assembled circular genome has a length of 16,569 bp which comprises 13 protein coding genes, 22 transfer RNA ...
