Six new species of Fusarium associated with soil and plant hosts from ecosystems of minimal anthropogenic disturbance in Australia are described. Fusarium coicis from Coix gasteenii, F. goolgardi ...from Xanthorrhoea glauca, F. mundagurra from soil and Mangifera indica, F. newnesense from soil, F. tjaetaba from Sorghum interjectum and F. tjaynera from soil, Triodia microstachya, Sorghum interjectum and Sorghum intrans. Morphology and phylogenetic analysis of EF-1α, RPB1 and RPB2 sequence data were used to delineate species boundaries. The new species were phylogenetically distributed in the Fusarium sambucinum, F. fujikuroi, and F. chlamydosporum species complexes, and two novel species complexes. These six new species have particular phylogeographic significance as not only do they provide further insight into the geographic patterns of Fusarium evolution but also challenge current phylogeographic hypotheses.
In this letter, we advocate recognizing the genus Fusarium as the sole name for a group that includes virtually all Fusarium species of importance in plant pathology, mycotoxicology, medicine, and ...basic research. This phylogenetically guided circumscription will free scientists from any obligation to use other genus names, including teleomorphs, for species nested within this clade, and preserve the application of the name Fusarium in the way it has been used for almost a century. Due to recent changes in the International Code of Nomenclature for algae, fungi, and plants, this is an urgent matter that requires community attention. The alternative is to break the longstanding concept of Fusarium into nine or more genera, and remove important taxa such as those in the F. solani species complex from the genus, a move we believe is unnecessary. Here we present taxonomic and nomenclatural proposals that will preserve established research connections and facilitate communication within and between research communities, and at the same time support strong scientific principles and good taxonomic practice.
Fusarium
is a large, complex genus that causes a wide variety of plant diseases, produces a number of mycotoxins and is becoming increasingly recognized as a significant human pathogen. These fungi ...occur in ecosystems in all parts of the globe, which makes them useful as a model to better understand biogeographic processes affecting the distribution of fungi. Here we review the information available on the biogeography of different species and clades of
Fusarium
and some of the likely processes affecting dispersal and speciation.
Many species in the Fusarium fujikuroi Species Complex (FFSC) have an affinity for grass species, with whom they live in an endophytic association or cause disease. We recovered isolates of Fusarium ...from agriculturally important grasses in Africa and Brazil, and characterized them with morphological markers, mating type, and Amplified Fragment Length Polymorphisms (AFLPs). We also conducted multi-locus phylogenetic analyses based on partial DNA sequences of translation elongation factor-1α (TEF1), β-tubulin (TUB), and the second largest subunit of RNA polymerase (RPB2) gene regions. Sexual cross fertility was used to test the biological species concept and the sexual stage of F. madaense is described. A novel species within the FFSC, Fusarium mirum, that is different from the other known species in the complex, was formally described. Fusarium mirum, F. madaense, and Fusarium andiyazi are a tightly intertwined species trio that are morphologically identical, but phylogenetically distinguishable, and amongst whom interspecific genetic exchange may still occur. These three species are so close that they cannot be reliably distinguished if only sequences of the TEF1 gene are used. In pathogenicity tests, all tested isolates of F. madaense from sugarcane, sorghum, maize, millet and Brachiaria could induce stalk rot in sorghum, maize and millet, and pokkah boeng in sugarcane. This study increases our understanding of the diversity of species within the FFSC that cause disease in tropical grasses or act as endophytes, and their geographic distributions. The genetically close relationship between F. mirum, F. madaense, and F. andiyazi provides an opportunity to study and identify factors underlying their limited inter-specific cross-fertility and sympatric speciation.
•Described a new species, F. mirum, closely related to F. madaense and F. andiyazi•Demonstrated pathogenicity of F. madaense and F. mirum on multiple known hosts•TEF-1 is very highly polymorphic amongst F. mirum, F. madaense and F. andiyazi•Some strains identified as F. andiyazi based on TEF-1 probably are F. madaense

ABSTRACT
This article is to alert medical mycologists and infectious disease specialists of recent name changes of medically important species of the filamentous mold
Fusarium
.
Fusarium
species can cause localized and life-threating infections in humans. Of the 70
Fusarium
species that have been reported to cause infections, close to one-third are members of the
Fusarium solani
species complex (FSSC), and they collectively account for approximately two-thirds of all reported
Fusarium
infections. Many of these species were recently given scientific names for the first time by a research group in the Netherlands, but they were misplaced in the genus
Neocosmospora
. In this paper, we present genetic arguments that strongly support inclusion of the FSSC in
Fusarium
. There are potentially serious consequences associated with using the name
Neocosmospora
for
Fusarium
species because clinicians need to be aware that fusaria are broadly resistant to the spectrum of antifungals that are currently available.

We investigate the signal propagation in AC-LGAD (aka RSD), which are LGAD with a common N+ layer and segmented AC-coupled readout contacts, by measuring the response to IR laser TCT on a large ...selection of AC-LGAD with strip readout. The interest for this topic derives from the realization that while large charge sharing between neighboring strips is essential for good position resolution, large sharing beyond the next neighbor generates background signals which in general are detrimental to the sensor goal of low occupancy. Using AC-LGAD with strip readout produced by Hamamatsu Photonics (HPK), we evaluate the effects of a variety of sensor properties, including geometrical parameters (strip length, width), process parameters like the N+ layer resistivity, the coupling capacitance, and the thickness of the bulk on the signal sharing and the position resolution.
•AC-LGAD are a new form of Ultra-Fast Silicon Detectors.•They have highly segmented readout reducing power consumption.•Signal sharing leads to high precision temporal and spatial resolution.
Given the rapid shift to in-home teleneuropsychology models, more research is needed to investigate the equivalence of non-facilitator models of teleneuropsychology delivery for people with younger ...onset dementia (YOD). This study aimed to determine whether equivalent performances were observed on neuropsychological measures administered in-person and via teleneuropsychology in a sample of people being investigated for YOD.
Using a randomized counterbalanced cross-over design, 43 participants (Mage = 60.26, SDage = 7.19) with a possible or probable YOD diagnosis completed 14 neuropsychological tests in-person and via teleneuropsychology, with a 2-week interval. Repeated measures t-tests, intraclass correlation coefficients (ICC), and Bland Altman analyses were used to investigate equivalence across the administration conditions.
No statistical differences were found between in-person and teleneuropsychology conditions, except for the Hospital Anxiety and Depression Scale Anxiety subtest. Small to negligible effect sizes were observed (ranging from .01 to .20). ICC estimates ranged from .71 to .97 across the neuropsychological measures. Bland Altman analyses revealed that the Wechsler Adult Intelligence Scale-Fourth Edition Block Design subtest had slightly better overall performance in the in-person condition and participants reported higher levels of anxiety symptoms during the teleneuropsychology condition; however, average anxiety symptoms remained within the clinically normal range. Participants reported a high level of acceptability for teleneuropsychology assessments.
These results suggest that performances are comparable between in-person and teleneuropsychology assessment modalities. Our findings support teleneuropsychology as a feasible alternative to in-person neuropsychological services for people under investigation of YOD, who face significant barriers in accessing timely diagnoses and treatment options.
The National Airborne Field Experiment 2006 (NAFE’06) was conducted during a three week period of November 2006 in the Murrumbidgee River catchment, located in southeastern Australia. One objective ...of NAFE’06 was to explore the suitability of the area for SMOS (Soil Moisture and Ocean Salinity) calibration/validation and develop downscaling and assimilation techniques for when SMOS does come on line. Airborne L-band brightness temperature was mapped at 1
km resolution 11 times (every 1–3 days) over a 40 by 55
km area in the Yanco region and 3 times over a 40 by 50
km area that includes Kyeamba Creek catchment. Moreover, multi-resolution, multi-angle and multi-spectral airborne data including surface temperature, surface reflectance (green, read and near infrared), lidar data and aerial photos were acquired over selected areas to develop downscaling algorithms and test multi-angle and multi-spectral retrieval approaches. The near-surface soil moisture was measured extensively on the ground in eight sampling areas concurrently with aircraft flights, and the soil moisture profile was continuously monitored at 41 sites. Preliminary analyses indicate that (i) the uncertainty of a single ground measurement was typically less than 5% vol. (ii) the spatial variability of ground measurements at 1
km resolution was up to 10% vol. and (iii) the validation of 1
km resolution L-band data is facilitated by selecting pixels with a spatial soil moisture variability lower than the point-scale uncertainty. The sensitivity of passive microwave and thermal data is also compared at 1
km resolution to illustrate the multi-spectral synergy for soil moisture monitoring at improved accuracy and resolution. The data described in this paper are available at
