Honeybee behavioural complexity: washboarding and neglected reasons to explain it

Sala 2.2.14, FCUL, Lisboa

Por Manuela Giovanetti (ESFE-cE3c).

Honeybees are exceptionally social animals that mankind domesticated back to the Stone Age. Nowadays honeybees do almost entirely survive thanks to the patient care of beekeepers, and feral colonies are rarely reported. Apis mellifera is constantly monitored and studied, especially concerning health issues and honey production. However, the fact that it was originally wild gets often neglected. This may instead be the reason for given behaviours, difficult to understand when placed in the context of managed conditions. Washboarding is one of them: bees stopping resource collection activities to concentrate on the front side of the hive while performing repetitive movements back and forth has been frequently recorded by beekeepers, but poorly investigated from a scientific point of view. I will introduce you to the first data, collected for a project investigating the possibility of washboarding being a vestigial behaviour. This behaviour could be linked to cleaning actions and to the facilitation of locating nest entrances. In a world not that heavily build-up by mankind, honeybee nests were mainly established in tree cavities, with tree trunks being rough surfaces even hosting various cryptogams. A combination of interviews, behavioural observations and experimental tests buildup, for the first time, scientific evidence on washboarding frequency and its dependence upon mechanical (smoothness of surface) and possibly chemical (cryptogam’s originated) cues.

Objectives: Evolutionary theory provides a framework for understanding all living systems.

Objectives: To introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

Objectives: Natural history museums are privileged spaces for seminal research on different subjects of biological sciences such as biodiversity, evolution, ecology, biogeography and taxonomy.

Objectives: Provide students with basic workflows, platforms and tools to increase reproducibility at all scientific levels.

Objectives: Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity.

Objectives: The objective of this course is to introduce participants to the details of communication and writing scientific publications. The main emphasis is on the most common form, the “primary scientific paper”, but other forms will be covered.

Objectives: Lack of fertile land to feed the exponentially growing population, insufficient water availability and quality, changes in the flow of nutrients through the bio-geo-cycles (especially N and P) and climate and land use changes are impacting ecosystem

Objectives: Symbiosis is a key strategy for life on Earth.

Objectives: The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects. It aims at providing an integrated approach on urban socio-ecological systems.

Objectives: Citizen science can be part of the larger process of engaging people in new forms of interaction in scientific research, challenging scientists and citizens whilst enlarging scientific knowledge and providing learning opportunities for all part

Objectives: This course aims at: 1) exploring how scientists can use social media as tools to enhance the communication of their research and the dialogue with society, and 2) discussing the differences that exist in the work of scientists and journalists
