New species and taxonomic changes in the Grevillea thelemanniana Group (Proteaceae: Grevilleoideae: Hakeinae) from south-west Western Australia

Four species are added to the Grevillea thelemanniana Group, the constituency of which is discussed in light of recent phylogenetic analyses. Two new species are described. Grevillea cooljarloo Keighery and Olde was previously included by some in Grevillea preissii Meisn. subsp. preissii or as G. pinaster divided-leaf form, and is presently known informally as Grevillea thelemanniana subsp. Cooljarloo (B.J. Keighery 28B) by the Western Australian Herbarium. Grevillea gillingarra Olde and Keighery has previously been confused with G. thelemanniana Hügel ex Endl. Grevillea preissii subsp. glabrilimba Olde and Marriott is here recognised at specific rank, as G. glabrilimba (Olde and Marriott) Olde. Grevillea preissii is more narrowly circumscribed, in line with the original concept sensu Meisner (1845), without subspecies. A photo of the Blaschka glass model of Grevillea preissii is included with permission. The historical confusion between G. thelemanniana and G. preissii is revisited. Grevillea variifolia subsp. bundera Keighery is recognised at species-level as G. bundera (Keighery) Olde and Keighery. A conservation assessment for all taxa is provided and a key to the revised Thelemanniana Group, as currently accepted, is supplied

Taxonomic revision of Corynotheca (Hemerocallidaceae / Asphodelaceae)

The genus Corynotheca F.Muell. ex Benth. is revised and Corynotheca borealis R.L.Barrett, Keighery & T.Macfarlane is described as a new species from the east Kimberley region of Western Australia and the adjacent Northern Territory. Corynotheca dichotoma (F.Muell.) F.Muell. ex Benth. is reinstated for a species growing on yellow sands in the Mid west of Western Australia. The taxonomic and geographic limits of varieties of C. micrantha (Lindl.) Druce are reconsidered and all are recognised at specific rank. Four new combinations are made: Corynotheca divaricata (R.J.F.Hend.) R.L.Barrett & T.Macfarlane, Corynotheca elongata (R.J.F.Hend.) R.L.Barrett & T.Macfarlane, Corynotheca gracilis (R.J.F.Hend.) R.L.Barrett & T.Macfarlane and Corynotheca panda (R.J.F.Hend.) R.L.Barrett & T.Macfarlane. All are illustrated and a revised key to the thirteen species of Corynotheca recognised is provided

A new species of Blennospora (Asteraceae: Gnaphalieae) from the Swan and Scott Coastal Plains of Western Australia

Abstract Keighery, G.J. A new species of Blennospora (Asteraceae: Gnaphalieae) from the Swan and Scott Coastal Plains. Nuytsia 15 (1): 33-36 (2002). A new species of Blennospora A. Gray, B. doliiformis Keighery, is described from the Swan and Scott Coastal Plains. The species occurs on clay soils in fresh winter-wet sites. A key is given to the three species now recognised in the genus

A hairy situation: Plant species in warm, sunny places are more likely to have pubescent leaves

Aim: Leaf pubescence has several important roles, including regulating heat balance, reducing damage from UV radiation, minimizing water loss and reducing herbivory. Each of these functions could affect a plant's ability to tolerate the biotic and abiotic stresses encountered in different parts of the world. However, we know remarkably little about large scale biogeographic patterns in leaf pubescence. Our aims were: (a) to determine whether a higher proportion of species have pubescence at sites where it is hot, dry and solar radiation is high, and (b) to quantify the latitudinal gradient in pubescence. Location: Australia. Taxon: Vascular land plants. Methods: We compiled data on the presence/absence of pubescence on mature photosynthetic organs for 4,183 species, spanning 107 families. We combined these data with over 1.9 million species occurrence records from the Atlas of Living Australia to calculate the proportion of species with pubescence in 3,261 grid cells spanning the Australian continent. Results: The proportion of pubescent species was most closely related to solar radiation (R2 = 0.33), followed by maximum temperature in the warmest month (R2 = 0.30). Mean annual precipitation was very weakly related to pubescence (R2 = 0.01). We found a significant negative relationship between latitude and pubescence (R2 = 0.19), with the average percentage of species with pubescence dropping from 46% at 10° S to 35% at 44° S. This cross-species relationship remained significant after accounting for phylogenetic relationships between species. We found that a quadratic model explained more variation in pubescence across latitudes than did a linear model. The quadratic model shows a peak in the proportion of pubescent species at 19° S (within the tropics). Main conclusions: Our findings are consistent with the idea that leaf pubescence may have a protective function in areas with high solar radiation and high temperatures. Our data are also consistent with the idea that species towards the tropics should be better defended than are species at higher latitudes

Effects of expectation on face perception and its association with expertise

Perceptual decisions are derived from the combination of priors and sensorial input. While priors are broadly understood to reflect experience/expertise developed over one’s lifetime, the role of perceptual expertise at the individual level has seldom been directly explored. Here, we manipulate probabilistic information associated with a high and low expertise category (faces and cars respectively), while assessing individual level of expertise with each category. 67 participants learned the probabilistic association between a color cue and each target category (face/car) in a behavioural categorization task. Neural activity (EEG) was then recorded in a similar paradigm in the same participants featuring the previously learned contingencies without the explicit task. Behaviourally, perception of the higher expertise category (faces) was modulated by expectation. Specifically, we observed facilitatory and interference effects when targets were correctly or incorrectly expected, which were also associated with independently measured individual levels of face expertise. Multivariate pattern analysis of the EEG signal revealed clear effects of expectation from 100 ms post stimulus, with significant decoding of the neural response to expected vs. not stimuli, when viewing identical images. Latency of peak decoding when participants saw faces was directly associated with individual level facilitation effects in the behavioural task. The current results not only provide time sensitive evidence of expectation effects on early perception but highlight the role of higher-level expertise on forming priors

With the exception of Palmer's recent survey, there is no quantitative data available on this important occupational grouping in the arts industry in Australia. The complex structural nature of the industry and the vastly different situations in which arts managers work further complicated the analysis. For this reason, the data collected may hold a bias towards arts managers who work for small to medium, membership-based, not-for-profit arts organisations, predominantly with voluntary boards and committees with a majority of artists holding membership. The principal objectives for this thesis were to locate any data on arts managers, to generate primary qualitative data, where at all possible, and to analyse both sources of data to identify the common elements of a work culture shared by arts managers. Five research methods were utilised to collect, code and analyse data on arts managers: • a literature review of published texts and articles that discussed arts industry, arts managers, arts management and the fields of management theory that related to work motivation and occupational politics; • a questionnaire survey circulated to a selection of 100 arts managers to collect key data on their career development and motivation for working in the field of arts management; • focus group meetings with arts managers discussing arts management issues to complement the empirical data gathered through the questionnaire survey; • summary and coding of the data for analysis from all sources; and, • framing and analysis of the data within contemporary management theory
