A Short Note on Undirected Fitch Graphs
The symmetric version of Fitch's xenology relation coincides with class of complete multipartite graph and thus cannot convey any non-trivial phylogenetic information.

Species (Cites) in 1989, to halt the steep decline in elephant numbers. “Wild elephant populations were decimated by the ivory trade. By the time the 1989 Cites ban came into force, Africa’s elephants had been reduced by more than 50 per cent,” says Mark Jones, programmes director at Care for the Wild, an international wildlife charity which commissioned the mammoth ivory report. “Poaching cont...
متن کاملFitchi: haplotype genealogy graphs based on the Fitch algorithm
UNLABELLED : In population genetics and phylogeography, haplotype genealogy graphs are important tools for the visualization of population structure based on sequence data. In this type of graph, node sizes are often drawn in proportion to haplotype frequencies and edge lengths represent the minimum number of mutations separating adjacent nodes. I here present Fitchi, a new program that produce...
متن کاملEnergy and water conservation in frozen vs. supercooled larvae of the goldenrod gall fly, Eurosta solidaginis (fitch) (Diptera: Tephritidae).
Insects that tolerate severe cold during winter may either supercool or tolerate ice forming within the tissues of the body. To compare the relative advantages of freezing and supercooling, we measured rates of CO(2) production and water loss in frozen and supercooled goldenrod gall fly larvae (Eurosta solidaginis). As an important first step, we measured the time required for ice content and m...
متن کاملFitch-Style Modal Lambda Calculi
Fitch-style modal deduction, in which modalities are eliminated by opening a subordinate proof, and introduced by shutting one, were investigated in the 1990s as a basis for lambda calculi. We show that such calculi have good computational properties for a variety of intuitionistic modal logics. Semantics are given in cartesian closed categories equipped with an adjunction of endofunctors, with...
