The Behaviour of Robber Honeybees [PDF]

open access: yesBehaviour, 1955
1. The factors which cause the characteristic swaying flight of robber honeybees have been investigated. 2. This flight occurs as an innate response to the presence of a congestion of bees, of their own or another colony, at the entrance to the hive they are robbing. 3.

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]

open access: yes, 2008
1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

Questioning public perception, conservation policy, and recovery actions for honeybees in North America

open access: yesConservation Biology, 2017
Global pollinator declines have resulted in an increasing number of policies and actions to help bee populations. In North America, there is strong public engagement, but also growing controversies over how to address declines.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

open access: yesSmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Data-driven honeybee antennal lobe model suggests how stimulus-onset asynchrony can aid odour segregation [PDF]

open access: yes, 2013
Insects have a remarkable ability to identify and track odour sources in multi-odour backgrounds. Recent behavioural experiments show that this ability relies on detecting millisecond stimulus asynchronies between odourants that originate from different ...

Nosema neumanni n. sp. (Microsporidia, Nosematidae), a new microsporidian parasite of honeybees, Apis mellifera in Uganda.

open access: yesEuropean Journal of Protistology, 2017
The microsporidium Nosema neumanni n. sp., a new parasite of the honeybee Apis mellifera is described based on its ultra-structural and molecular characteristics.

Sex Determination in the Honeybee [PDF]

open access: yesCell, 2003
Sex determination in honeybees involves a multi-allelic locus, such that homozygotes develop as males and heterozygotes as females. In this issue of Cell, report the cloning of the sex-determining gene, csd. It codes for an SR protein, and different alleles have very different amino-acid sequences. Inactivating csd leads to development as a male.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Insights on the nutritional ecology of a nocturnal pollinating insect

open access: yesInsect Science, EarlyView.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.
