Although the forces behind the evolution of imperfect mimicry remain poorly studied, recent hypotheses suggest that relaxed selection on small-bodied individuals leads to imperfect mimicry. While evolutionary history undoubtedly affects the development of imperfect mimicry, ecological community context has largely been ignored and may be an important driver of imperfect mimicry. Here we investi...

Animal sensory systems are optimally adapted to those features typically encountered in natural surrounds, thus allowing neurons with limited bandwidth to encode challengingly large input ranges. Natural scenes are not random, and peripheral visual systems in vertebrates and insects have evolved to respond efficiently to their typical spatial statistics. The mammalian visual cortex is also tune...

We describe and characterize an experimental system to perform shape measurements on deformable objects using high-speed close-range photogrammetry. The eventual application is to extract the kinematics of several marked points on an insect wing during tethered and hovering flight. We investigate the performance of the system with a small number of views and determine an empirical relation betw...

The results of the hoverfly (Syrphidae) collection by the ‘Malloch Society’ on the Greek island of Lesvos are presented. Fieldwork took place from February to March 2006 and from May to June 2010. An account of 66 species from 28 genera is provided including two species new to science, five species new to Greece and data for several rarely recorded species. We describe Eumerus armatus Ricarte a...

• "The hallmarks of aging" is the most highly cited article in aging research. While provides a useful overview, fails as an explanatory paradigm. Its widespread adoption obscures urgent need to develop genuine paradigms during time transition field. Biogerontology needs look beyond understand process aging. With goal representing common denominators different organisms López-Otín et al. 2013 d...
