TWO SPECIALLY SIGNIFICANT EXAMPLES OF INSECT MIMICRY

Behavior in Insect Mimicry

Arthropods use insect mimicry to gain predatory advantages over other insects in the form of increased resource availability and protection from predators. They do this through several different mechanisms, 4 of which are described in the paper; Batesian, Peckhamian, Wasmannian, and Tephritid mimicry. ‘Mimicry’ includes resemblances in both appearance and behavior. Without mimicry in both appea...

Nabokov, Teleology, and Insect Mimicry

Insect mimicry of plants dates back to the Permian

In response to predation pressure, some insects have developed spectacular plant mimicry strategies (homomorphy), involving important changes in their morphology. The fossil record of plant mimicry provides clues to the importance of predation pressure in the deep past. Surprisingly, to date, the oldest confirmed records of insect leaf mimicry are Mesozoic. Here we document a crucial step in th...

Two Examples of Affine Manifolds

An affine manifold is a manifold with a distinguished system of affine coordinates, namely, an open covering by charts which map homeomorphically onto open sets in an affine space E such that on overlapping charts the homeomorphisms differ by an affine automorphism of E. Some, but certainly not all, affine manifolds arise as quotients Ω/Γ of a domain in E by a discrete group Γ of affine transfo...

Generating Significant Examples for Conceptual Schema Validation Confidential

This report bases itself on the idea of using concrete examples to verify conceptual schemas, and in particular cardinality constraints. When novice ORM modellers model domains, the selection of proper cardinality constraints for relationship types is quite often prone to errors. In this report we propose a mechanism for the generation of significant examples for selected subschemas. The genera...
