Bird pollination of Canary Island endemic plants
The Canary Islands are home to a guild of endemic, threatened bird pollinated plants. Previous work has suggested that these plants evolved floral traits as adaptations to pollination by flower sp…

Towards a cognitive definition of colour vision
In recent years, colour vision abilities have been rather generously awarded to vari-ous invertebrates and even bacteria. This uncertainty of when to diagnose colour vi-sion stems in part from conf…

FReD: The floral reflectance spectra database
Floral reflectance measurements are of great value to researchers who need consider the real colour of flowers, for example in the context of how the flowers appear to their pollinators. We have th…

Bumblebees under the midnight sun – Monitoring circadian rhythms of bumblebees under continuous daylight, using radio frequency identification (RFID)
Circadian rhythms enable organisms to anticipate and to prepare for predictable changes in their environment. Most previous studies on circadian rhythms focused on solitary animals. However, in soc…

Bumblebees gain fitness through learning
Despite the widespread assumption that the learning abilities of animals are adapted to the particular environments in which they operate, the quantitative effects of learning performance on fitnes…

Cognitive dimensions of predator responses to imperfect mimicry?
Many palatable insects, for example hoverflies, deter predators by mimicking well-defended insects such as wasps. However, for human observers, these flies often seem to be little better than caric…
