Three major groups of pigments, the betalains, the carotenoids, and the anthocyanins, are
responsible for the attractive natural display of flower colors. Because of the broad …

A number of studies have explored visual symmetry processing by measuring event related
potentials and neural oscillatory activity. There is a sustained posterior negativity (SPN) …

Bumblebees are familiar and charismatic insects, occurring throughout much of the world.
They are increasingly being used as a model organism for studying a wide range of …

In the arts and sciences, as well as in our daily lives, symmetry has made a profound and
lasting impact. Likewise, a computational treatment of symmetry and group theory (the …

This paper provides a step-by-step guide for the morphological analysis of corolla and the
decomposition of corolla shape variation into its symmetric and asymmetric components …

Symmetry is a defining feature of floral diversity. Here we review the evolutionary and
ecological context of floral symmetry (adding new data regarding its distribution), as well as …

Categorization refers to the classification of perceptual input into defined functional groups.
We present and discuss evidence suggesting that stimulus categorization can also be found …

Paleontological and phylogenetic studies have shown that floral zygomorphy (bilateral
symmetry) has evolved independently in several plant groups from actinomorphic (radially …

Despite the rapid growth of research on the crossmodal correspondence between visually
presented shapes and basic tastes (eg, sweet, sour, bitter, and salty), most studies that have …

This review provides evidence for the enormous richness of insect behavior, its high
flexibility, and the cross-talk between different behavioral routines. The memory structure …
