Detection of an Introduced Bacterial Culture in Greywater Treatment Reactors
This research describes overall bacterial community structure within a greywater wastewater treatment reactor, and identifies one specific bacterial inoculum. Biological samples were removed from both the unattached (planktonic) and surface-adherent (biofilm) populations in several inoculated …

Does Urbanization Facilitate the Establishment of Introduced Monk Parakeet (Myiopsitta monachus) Populations?
… (Myiopsitta monachus) is a prime example of an introduced species that has gone through the colonization process and successfully established breeding populations in urban environments. While much of this is due to urban areas being a common point of introduction (release) for exotic species, …

Patterns of association in a co-introduced insect herbivore and parasitoid wasp
… areas. By tracing the invasion routes of co-introduced species that share a close evolutionary history in their native range, I address the relative importance of long-term historical associations versus ecological fitting in community assembly. In the context of invasion ecology, ecological …

Effects of Introduced Muskrat Populations on Emergent Vegetation in South Dakota Wetland
Muskrats (Ondatra zibethicus) and fluctuations of water level are the main forces controlling wetland vegetation cover and composition on a long term basis. IN the absence of artificial water control structures, properly managed muskrat populations are the most natural, long term means of …

Experiences of Physical Sciences teachers when introduced to an electronic expert system
This study outlines the strategies that were employed during the training of Grade 11 Physical Sciences teachers in the use and development of an Electronic Performance Support System (EPSS). The EPSS process involves extended individualised support for teachers through face-to-face training. A …

Creativity with Purest Energy: How Sir Thomas Wyatt Introduced Modern English Poetics
… poetry from Italy, France and elsewhere, Wyatt introduced numerous poetic forms to England. Then, by experimenting with these new metrical forms and using native vernacular, he originated his own poetry. Wyatt's poetry also began to reflect a new attitude about human life, an attitude reflecting …

Nanoscale Patterning of Chemical Order Introduced by Displacement Cascades in Irradiated Alloys
We test the predictions on the Ni3Al compound by combining molecular dynamics (MD) and KMC simulations. For 1MeV Kr and 70keV He ions, MD simulations are used to simulate the disordered zones, which are then incorporated into KMC simulations to reach long irradiation times. These simulations …

The effects of introduced mice on seabirds breeding at sub-Antarctic Islands
… globally threatened and at risk of extinction. Introduced predators at oceanic islands where many seabirds breed account for the largest proportion of population declines, more so than incidental fisheries bycatch or degradation of their breeding habitats. Since few oceanic islands have escaped …

Impacts of the introduced house mouse on the seabirds of Gough Island
Introduced house mice Mus musculus on Gough Island were suspected of widespread predation of Atlantic Petrel Pterodroma incerta and Tristan Albatross Diomedia dabbenena chicks in 2000/01. Video cameras recorded six fatal attacks by mice on live, healthy Atlantic Petrel chicks in 2004. Crude …

Exogenously-introduced Homing Endonucleases Catalyze Double-stranded DNA Breaks in Aedes aegypti
… Recognition sequences for various rHEs were introduced into Ae. aegypti through germline transformation, and imperfect repair at each of these exogenous sites was evaluated. In mosquitoes containing a single exogenous HE site, imperfect gap repair was detected in 40% and 21% of clones …

Interference in White Bass Reproduction by Two Introduced Predators in Barren River Lake, Kentucky
… same time, two congeners of white bass have been introduced to the lake. Hybrid striped bass Morone chrysops × Morone saxatilis were introduced in 1979 and yellow bass Morone mississippiensis were first discovered in 2000. Due to the similar life histories and spawning strategies of all three …

Biodegradation of tertiary butyl alcohol by an introduced Pseudomonas sp. in subsurface soil microcosms
Microcosm studies determined that the indigenous microflora of the subsurface Groseclose clayey loam did not metabolize TBA, but TBA degradation was stimulated by the addition of the Pseudomonas sp., VT100. The indigenous subsurface microflora of the Fredrick clay metabolized TBA in soil microcosms …

Impacts of the introduced crabs, Carcinus maenas and Hemigrapsus sanguineus, in northern New England
<p>Two introduced crab species are presently found in northern New England, Carcinus maenas, which has been in this region for over 100 years, and Hemigrapsus sanguineus which was first reported in New Hampshire in 1998. Carcinus maenas is a generalized predator and its introduction has had …

Probing the Structure of Apolipoprotein AI by Specific Fluorescent Labeling of Introduced Cysteine Residues
Based on this study and previous results, a model of lipid-free proapoAI was constructed. This model takes into account the elongated shape of proapoAI, indicates that the N- and C-terminal extremes of proapoAI are compact, the C-terminal region is within 40 A of the 5 Trp residues in the …
