A preliminary census of the macrofungi of Mount Wellington, Tasmania- the Agaricales
The macro fungi of Tasmania are part of a kingdom of living organisms that is poorly known in Australia; most species are unnamed and undescribed. The present work represents an initial attempt at identifying the rich mycobiota of Mount Wellington, one of Tasmania's best-known and most-studied regions for other plant groups. Attention is confined to the 'gilled' fungi, the order Agaricales. The agarics of Mount Wellington comprise a very large group, and in the 15 families recognised, 130 previously named and described species are differentiated and presented here. The true number of species is at least twice that many, as some large families have been inadequately studied in Australia. For example, in the family Entolomataceae, we believe there are over 50 distinct species in the genus Entoloma and at least four species in the genus Rhodocybe on Mount Wellington
A preliminary census of the macro fungi of Mt Wellington, Tasmania the Ascomycota
This work continues the process of documenting the macrofungi of Mt Wellington. Two earlier publications were concerned with the and non-gilled Basidiomycota, respectively, excluding the sequestrate species. The present work deals with the non-sequestrate Ascomycota of which 42 species were found on Mt Wellington
A preliminary census of the macrofungi of Mt Wellington, Tasmania the non-gilled Basidiomycota
This work is a further contribution towards documenting the macrofungi ofMt Wellington. An earlier publication was confined to 130 named and described of 'agarics', or gilled fungi. The focus of the present paper is on the non-gilled Basidiomycota with the exception of the sequestrate which will be the subject of a separate A total of 65 non-gilled is included here. Further, the acquisition of recent information has added 11 species to the previous list of gilled fungi and enabled two of the names to be revised
Wood-inhabiting macrofungal assemblages in 43-year-old regenerating wet Eucalyptus Obliqua L'Her.Forest
This study focuses on the diversity and ecology of wood-inhabiting macrofungal species assemblages in a regenerating tall, wet, native Eucalyptus obliqua forest in southeast Tasmania, 43 years after natural and anthropogenic disturbances. Two plots subjected to "clearfell, burn and sow" silviculture were compared with two other nearby plots that had experienced wildfire. A total of 90 species was identified from 619 macro fungal records during six fortnightly visits between May and July 2010. The plots with abundant live Pomaderris ape tala trees in the understorey (i.e., those at Edwards Rd) had markedly different macrofungal assemblages from those with no or with sparse Pomaderris apetala (i.e., at Hartz Rd). This study provided evidence that a 43-year-old regenerating forest maintains a core of common wood-inhabiting macrofungal species irrespective of type of disturbance. Furthermore, species most frequently observed in older forests in Tasmania can also occur in younger managed forests if biological legacies such as large diameter wood, well-decayed wood, large living trees and a diversity of tree species remain after silvicultural treatment
A preliminary census of the macrofungi of Mt Wellington, Tasmania- the sequestrate species
This is the fourth and final contribution in a series of papers providing a preliminary documentation of the macrofungi of Mt Wellington, Tasmania. The earlier papers dealt with the gilled Basidiomycota, the non-gilled Basidiomycota and the Ascomycota, respectively, excluding the sequestrate species. The present paper completes the series by dealing with the sequestrate species, of which seven Ascomycota, 76 Basidiomycota, three Glomeromycota and one Zygomycota were found. Seven new genera and 25 new species to be formally described elsewhere, are recorded
General Gauge Mediation with Gauge Messengers
We generalize the General Gauge Mediation formalism to allow for the
possibility of gauge messengers. Gauge messengers occur when charged matter
fields of the susy-breaking sector have non-zero F-terms, which leads to
tree-level, susy-breaking mass splittings in the gauge fields. A classic
example is that SU(5) / SU(3) x SU(2) x U(1) gauge fields could be gauge
messengers. We give a completely general, model independent, current-algebra
based analysis of gauge messenger mediation of susy-breaking to the visible
sector. Characteristic aspects of gauge messengers include enhanced
contributions to gaugino masses, (tachyonic) sfermion mass-squareds generated
already at one loop, and also at two loops, and significant one-loop A-terms,
already at the messenger scale.Comment: 79 pages, 5 figure
Photolithographic Approaches for Fabricating Highly Ordered Nanopatterned Arrays
In this work, we report that large area metal nanowire and polymer nanotube arrays were successfully patterned by photolithographic approach using anodic aluminum oxide (AAO) templates. Nanowires were produced by electrochemical deposition, and nanotubes by solution-wetting. The highly ordered patterns of nanowire and nanotube arrays were observed using scanning electron microscopy (SEM) and found to stand free on the substrate. The method is expected to play an important role in the application of microdevices in the future
