Partisan Cities: How State‐Local Political Alignment Shapes Credit Risk and Information Processing in the Municipal Bond Market

Journal of Accounting Research, EarlyView.
ABSTRACT This paper studies how partisan alignment between city leaders and state governors shapes information processing and bond pricing in the municipal bond market. Using a novel data set on 1,045 U.S. cities from 2005 to 2019, we show that cities with the same political affiliation as the state governor face 9 basis points lower borrowing costs ...

Testing in Vitro of an Apifitoterapeutic Formula Against Nosema spp.

Scientific Papers Animal Science and Biotechnologies, 2023
Nosema, a parasitic disease that affects adult honey bees, has a directly correlation with the losses of bee colonies, until to depopulation. The target of our study was to determine the antinosema action of an apifitoterapeutic formula that was obtained

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Honey Bee Pollination of Camellia oleifera and Mitigation of Toxic Crop Nectar

Insects
Tea oil tree (Camellia oleifera), a woody oil crop native to Southern China, relies on insect pollination for fruit and seed production. However, its nectar is toxic to honey bees (Apis spp.) due to their inability to digest the oligosaccharide present ...

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

Integrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

Coinvasional disruptions to island pollinator networks

Conservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

Ecological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

Insect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial
