We compiled a checklist of the amphibians and reptiles of the state of Coahuila, Mexico. The list comprises 133 species (24 amphibians, 109 reptiles), representing 27 families (9 amphibians, 18 reptiles) and 65 genera (16 amphibians, 49 reptiles). Coahuila has a high richness of lizards in the genus Sceloporus. Coahuila has relatively few state endemics, but has several regional endemics. Overl...
Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of the world's mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine mammals. Global macroecological patterns are very different for land and marine species but suggest common mec...
UNLABELLED Many algorithms analyze enhancers for overrepresentation of known and novel motifs, with the goal of identifying binding sites for direct regulators of gene expression. Twine is a Java GUI with multiple graphical representations ('Views') of enhancer alignments that displays motifs, as IUPAC consensus sequences or position frequency matrices, in the context of phylogenetic conservati...
—Effective population size (Ne) is an important concept in the management of threatened species like bull trout Salvelinus confluentus. General guidelines suggest that effective population sizes of 50 or 500 are essential to minimize inbreeding effects or maintain adaptive genetic variation, respectively. Although Ne strongly depends on census population size, it also depends on demographic and...
The infection of the oral cavity is a common public health problem and constant cause for antibiotic prescription, with 10% of antibiotics used to treat this problem. However, few studies have so far aimed to determine its incidence. Added to this, its relationship with certain sytemic diseases (cardiac, endocrine, etc) confers this pathology vital importance. In spite of the frequency and impo...

Multiple non-animal-based test methods have never been formally validated. In order to use such new approach methods (NAMs) in a regulatory context, criteria to define their readiness are necessary. The field of developmental neurotoxicity (DNT) testing is used to exemplify the application of readiness criteria. The costs and number of untested chemicals are overwhelming for in vivo DNT testing...
This corpus-based study aimed at exploring the most frequently-used academic words in linguistics and compare the wordlist with the distribution of high frequency words in Coxhead’s Academic Word List (AWL) and West’s General Service List (GSL) to examine their coverage within the linguistics corpus. To this end, a corpus of 700 linguistics research articles (LRAC), consisting of approximately ...
This talk consists of two parts. In the first, the present experimental bounds on the anomalous couplings of the gauge bosons, based mainly on the LEP and Tevatron experiments, are reviewed. In the second part, the theorem of helicity conservation (HC) is presented, which should be valid in either the Standard Model (SM) or MSSM, for any two-body process at high energies and fixed angles. The e...
Spatial multicriteria models may provide an equitable and efficient means for incorporating people’s preferences in social decisions. However, in order for these tools to be effective, they should include criteria that are locally relevant and measurable in a spatial framework. This paper integrates measures of stakeholder preferences with GIS data in a spatial multicriteria framework for ident...
