Further experiments on the drifting of honey-bees [PDF]
, 1961 1. Worker bees learnt the colour of their hive in the close vicinity to their hive entrance and took little or no notice of colours above the lower brood chamber. They orientated to a colour below the entrance more than to a colour above.

The Not‐So‐Neue Frau: Weimar Berlin's Modern Women and Generational Identity After 1945
Gender &History, EarlyView.ABSTRACT This article studies the post‐1945 literary careers of Gabriele Tergit and Ilse Langner, two ageing German writers. Both had enjoyed promising careers as young women in Weimar Berlin, but Nazism and war disrupted their professional trajectories in varying ways. After 1945, they tried and failed to recapture their Weimar‐era success, eventually

COMMON SENSE LAW: Making Right/s in the Liberal City
International Journal of Urban and Regional Research, EarlyView.Abstract This article, co‐authored by encampment and university scholars, is concerned with how homeless persons challenge rightlessness. We do so by advancing a conceptual framework of common sense law, arguing that such contestations take place not only in courtrooms but also in the lived spaces of homelessness.

Pathogenicity of
mBio, 2018 Although few honey bee diseases are known to be caused by bacteria, pathogens of adult worker bees may be underrecognized due to social immunity mechanisms. Specifically, infected adult bees typically abandon the hive or are removed by guards.

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

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.

Colour reverse learning and animal personalities: the advantage of behavioural diversity assessed with agent-based simulations [PDF]
, 2012 Foraging bees use colour cues to help identify rewarding from unrewarding flowers, but as conditions change, bees may require behavioural flexibility to reverse their learnt preferences.

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.
