Treemap Versus BPA (Again): A Response To Dowling
نویسندگان
چکیده
TreeMap is a computer program for analysing host-parasite cospeciation. We respond to Dowling’s (Cladistics, 18: 416-435) recent comparison of TreeMap and Brooks Parsimony Analysis (BPA) by showing that Dowling’s comparison suffers from several mistakes and flaws. We discuss the problems with both BPA and TreeMap, and show that BPA incorrectly counts the true number coevolutionary events more often than TreeMap 1. We also discuss the two main limitations of TreeMap 1 correctly identified by Dowling, namely its inability to handle widespread parasites, and its coarse optimality criterion (the number of cospeciation events). We suggest a simple fix for widespread parasites. The newly released TreeMap 2 uses a more sensitive optimality criterion than TreeMap 1, addressing Dowling’s second concern.

Dowling-Degos disease: Report of a case with pigmentation localized only in the genital area
Dowling –Degos disease is a rare condition. It is inherited by an autosomal dominant gene. It usually presents in adult life as small, pigmented, asymptomatic macules in flexural regions. We report a 35-year-old woman with Dowling- Degos disease, in whom the reticular pigmentation confined to the genital area.

Background and purpose: Bisphenol A (BPA) is a toxic environmental pollutant that is released from different industries. The aim of this study was to investigate bisphenol A adsorption by activated carbon production from almond shell applying response surface methodology (RSM). Materials and methods: In this descriptive-analytic study, activated carbon production from almond shell was used as ...
متن کاملComputational aspects of host-parasite phylogenies
Computational aspects of host-parasite phylogenies form part of a set of general associations between areas and organisms, hosts and parasites, and species and genes. The problem is not new and the commonalities of exploring vicariance biogeography (organisms tracking areas) and host-parasite co-speciation (parasites tracking hosts) have been recognised for some time. Methods for comparing host...
متن کاملVitellogenin Gene Expression and Sex Steroid Levels as Biomarkers in Yellowfin Seabream (Acanthopagrus latus) Exposed to Bisphenol-A
Background: The egg yolk precursor protein vitellogenin (VTG) has proven to be a useful biomarker, used to identify organisms exposed to estrogenic compounds. Methods: We investigated variations in the VTG gene expression pattern and plasma sex steroid hormones concentrations in the yellowfin Seabream, Acanthopagrus latus, (A. latus) by various doses of bisphenol-A (BPA) exposure for 7 and 14 ...
متن کاملAssociation of Dowling-Degos disease and multiple seborrheick-eratosis in a “Christmas tree pattern”
Dowling-Degos disease is a rare sporadic or autosomal dominant pigmentary entity, in which clusters of papules and reticulate macules slowly develop with predominance in flexural regions. This entity is due to mutations in the keratin 5 gene, and is related with other cutaneous disorders. We report the sporadic form of Dowling-Degos disease in an elderly man with multiple seborrheickeratosis ...
