Ageniella Banks, 1912 is a paraphyletic group exclusive to the Nearctic and Neotropical regions. The genus has remarkable morphological diversity among species strong sexual dimorphism, hampering taxonomic studies of it. Herein, we add two new fauna Ageniella: A. caerulea sp. nov. belonging subgenus Ameragenia ruschi Priophanes; both are described illustrated. A brief discussion subgeneric char...

Chytridiomycosis is an emerging infectious disease caused by the pathogen Batrachochytrium dendrobatidis and has been linked to the decline and extinction of amphibian species throughout the world. B. dendrobatidis was first detected in Tasmania in 2004 and subsequently found in a range of urban and rural habitats in eastern and northern parts of the State. We report on a survey of the distribu...

A simulated annealing algorithm is employed to generate a stochastic model for a Berea sandstone and a Fontainebleau sandstone, with each a prescribed two-point probability function, lineal-path function, and "pore size" distribution function, respectively. We find that the temperature decrease of the annealing has to be rather quick to yield isotropic and percolating configurations. A comparis...

The Nam Pat Group of the Nam Pat Basin, Uttaradit Province, Thailand is situated in the Nan Suture Zone. Two contrasting tectonic framework models of the Nan Suture have previously been proposed: as a main Paleo-Tethyan suture and as a remnant of a closed back-arc basin. The goal of this study is to analyze the tectonic framework of the Nan Suture and reevaluate the existing tectonic models. Th...

A famous and well known Australian inselberg,1 Uluru,2 is an interesting geological feature in that its geomorphology is still a matter of controversy among conventional geologists. Traditionally, Uluru’s stratigraphical history began hundreds of millions of years ago, being fashioned into its current contour only as recently as between 60 million years ago until the present. The process by whi...

Currently, >35 Saudi Arabian medicinal plants are traditionally used for various liver disorders without a scientific rationale. This is the first experimental evaluation of the anti-hepatitis B virus (HBV) potential of the total ethanolic and sequential organic extracts of 60 candidate medicinal plants. The extracts were tested for toxicity on HepG2.2.15 cells and cytotoxicity concentration (C...

Like many other species of petrel, blue petrel (Halobaena caerulea) are able to return to their nest burrows at night in complete darkness. Since petrels have a well-developed olfactory system, we carried out an experiment to test whether blue petrels use olfaction to localise their nest burrows. Incubating birds were injected intranasally with a zinc sulphate solution, which reversibly impairs...

A new species of Burttia Dirsh, B. caerulea sp. nov., is described from the Nguru Mountains Tanzania. It second in genus, both being restricted to Tanzanian localities. Both sylvatica , known only Uluguru Mountains, and nov. are morphologically very similar habitus outer morphology, suggesting a recent speciation.
