Anarchy in the UK: Detailed genetic analysis of worker reproduction in a naturally occurring British anarchistic honeybee, Apis mellifera, colony using DNA microsatellites [PDF]

open access: yes, 2002
Anarchistic behaviour is a very rare phenotype of honeybee colonies. In an anarchistic colony, many workers’ sons are reared in the presence of the queen. Anarchy has previously been described in only two Australian colonies.

Assessing TiO2/Chitosan‐Based Hydrogels for Water Remediation: Sunlight‐Driven Degradation of Antibiotics in Water

open access: yesAdvanced Materials Interfaces, EarlyView.
Chitosan–TiO2 composite hydrogels combine adsorption of organic pollutants with photocatalysis, allowing to remove 85% of a broadly diffused antibiotic (sulfamethoxazole) under direct sunlight irradiation, opening great promises for point‐of‐use, outdoor applications.

Removal new alternative to chemical and mechanical removal for the study of pollen carried on the wild bee scopae

open access: yesRevista del Museo Argentino de Ciencias Naturales, 2010
Eliminación de una nueva alternativa a la eliminación química y mecánica para el estudio del polen transportado en las abejas silvestres. El reconocimiento taxonómico y la cuantificación de los diferentes tipos de polen recogidos por las abejas ofrecen el método más directo para estudiar la dieta.
