We introduce an approach to revealing the likelihood of different population histories that utilizes an explicit model of sequence evolution for the DNA segment under study. Based on a phylogenetic tree reconstruction method we show that a Tamura-Nei model with heterogeneous mutation rates is a fair description of the evolutionary process of the hypervariable region I of the mitochondrial DNA f...
Conservation increasingly operates at the landscape scale. For this to be effective, we need landscape scale information on species distributions and the environmental factors that underpin them. Species records are becoming increasingly available via data centres and online portals, but they are often patchy and biased. We demonstrate how such data can yield useful habitat suitability models, ...
The Formosan subterranean termite, Coptotermes formosanus Shiraki is currently one of the most destructive pests in the USA. It is estimated to cost consumers over US dollars 1 billion annually for preventative and remedial treatment and to repair damage caused by this insect. The mission of the Formosan Subterranean Termite Research Unit of the Agricultural Research Service is to demonstrate t...
This paper is concerned with option pricing in an incomplete market driven by a jumpdiffusion process. We price options according to the principle of utility indifference. Our main contribution is an efficient multi-nomial tree method for computing the utility indifference prices for both European and American options. Moreover, we conduct an extensive numerical study to examine how the indiffe...

Populations of adult chironomids occurring along 5-6 km of waterfront in the city of Sanford facing Lake Monroe, central Florida, were monitored from January 1980 to December 1994 using New Jersey light traps. The annual mean number of total midges per trap per day ranged from 269 (1994) to 8,009 (1980). Among the more than 20 species of midges occurring in the traps, Glyptotendipes paripes was...
BACKGROUND In 2000, the USDHHS released Healthy People 2010 (HP2010), a series of disease prevention and health promotion objectives for the nation. Thirty-nine of these objectives were dedicated to injury prevention and six of these objectives related to adolescents, who were tracked through CDC's National Youth Risk Behavior Survey (YRBS). PURPOSE This paper uses national YRBS data from 199...
This paper reports on three species of mites of the genus Laelaspis in Iran - Laelaspis calidus Berlese from Pheidole pallidula, Laelaspis humeratus (Berlese) from Tetramorium caespitum and Laelaspis dariusi Joharchi & Jalaeian, sp. n. fromsoil. The new species is described and illustrations provided.
Characterisation of fractured rocks and evaluation of fracture connectivity are essential for the study of subsurface flow and transport in fractured rock aquifers. In this study, we use a new method to present fracture networks and analyse the connectivity of the fractures, based on the technique of randomly-generated realisations. The application of the method aims to provide more detailed in...
The generic concepts of Archaeoteleia Masner and Proteroscelio Brues are expanded to accommodate two new species that are here described: Archaeoteleia astropulvis Talamas sp. n. and Proteroscelio nexus Talamas sp. n. A specimen of Archaeoteleia from Baltic amber is illustrated and discussed. Diagnoses of Proteroscelio, Proterosceliopsis Ortega-Blanco, McKellar & Engel and Bruescelio Ortega-Bla...
