Abstract:

Recent data on monocotyledonous geophytes from south-western Australia are compiled and compared with those from other areas of mainly mediterranean climate, especially California, Chile and Victoria, Australia. South-western Australia has a high monocot geophyte diversity of 496 species (7% of an estimated native flora of 7100 vascular species), like Victoria (12%) and the Cape region (14%). As in Victoria, orchids are by far the most important group, with c. 400 species, including those likely to be described once ongoing taxonomic research is completed. South-western Australia has higher geophyte numbers than Victoria in all families considered, but a lower geophyte percentage because of a much higher vascular species total. Among south-western Australian non-orchid geophytes, as in Victoria, the most common storage organ is tuberous roots, followed by corms then bulbs and rhizomes, whereas in California bulbs are by far the most common. The presence of microgeophytes with seed-like storage organs is a special feature seen in several phylogenetically unrelated lineages in the south-western Australian and Victorian geophytic flora, especially on granite outcrops. Divergent phylogenetic history is undoubtedly a major factor underlying striking differences between the monocot geophytes of mediterranean Australia, California, Chile, South Africa and Mediterranean countries. Further studies, particularly on the last two regions, will enable better elucidation of these patterns.

Abstract:

An established population of Cream Pincushions (Scabieuse jaune pâle, Scabiosa ochroleuca L.) in the Ottawa Valley approximately 16.5 km southeast of Arnprior is new to the flora of Ontario and eastern Canada. Other Canadian reports include a nonpersisting occurrence in Victoria, British Columbia, in 1908 and a recent occurrence from Keremeos in southcentral British Columbia. Identification and ecology of this species are discussed. In the Ottawa Valley, the plant occurs with introduced Heath Snail (Xerolenta obvia), which also originates in eastern Europe.

Full text

Abstract:

Forms previously recognised within Eucalyptus alpina Lindl., an endemic of the Grampian Ranges, Victoria, are described as three new species. E. victoriana sp. nov. occurs in the Mt Thackeray area, Victoria Range; it is a tall tree with smooth upper branches and flaky bark on the lower trunk, adult leaves which are broad-lanceolate, buds which are slightly warty, and fruits which are compressed-hemispherical with a level to slightly ascending disc. E. serraensis sp. nov. is a small tree or mallee of the Wonderland Range and northern Serra Range; adult leaves are ovate, apiculate and coriaceous, buds are warty, and fruits have a broad, distinctly raised disc. E. verrucosa sp. nov. is a small tree or shrub of the southern Sena Range; adult leaves are orbicular, emarginate and coriaceous, buds are very warty, and fruits are large, with a level and folded disc. The type for E. alpina is from a probable hybrid tree with E. baxteri (Benth.) Maiden & Blakely ex Black and hence the name cannot be applied to any of the taxa recognised here.

Full text

Abstract:

The pool of carbon in the world's forests is of similar magnitude to that in the atmosphere, yet little attention has been given to improving measures of carbon in terrestrial biomass. Much of the critical data for forest biomass on which models of global carbon cycling rely is, in fact, based on the accurate sampling of less than 100 ha of forest. Uncertainties in biomass estimation at the local and regional level may be responsible for much of the current speculation as to unidentified sinks for carbon. We have used a forest inventory (i.e. records of forest volume obtained for harvesting purposes) approach to quantify the biomass of forests in Victoria, Australia. Forests were analysed by type, age and region. Regression equations were developed for the accumulation of biomass with age across all productivity classes for each forest type. The mean carbon density for above-ground components of Victorian native forests is 157 tonnes ha-1 (t ha-1), although forest types range in mean carbon density from 250 to 18 t ha-1. Pinus radiata D. Don plantations in Victoria have a mean carbon density of 91 t ha-1 in the above-ground components. Total carbon stored in above-ground biomass is estimated to be 1.2 X 109 t. Rates of carbon fixation vary with forest age, species and site. Mountain ash (Eucalyptus regnans F. Muell.) forests fix around 9 t of carbon ha-1 annually during the first few years of growth, decreasing to 6 t ha-1 by age 10. Rates of carbon accumulation by other forests are generally less than this and, at the lower end of the range, box-ironbark forests, mallee and woodlands accumulate between 0.5 and 2 t ha-1 year-1. P. radiata plantations in Victoria will accumulate around 7 t carbon ha-1 year-1.

Full text

Abstract:

Varroa destructor is a parasitic mite, which is considered a severe pest for honey bees causing serious losses to beekeeping. Residual hydrolats from steam extraction of hop essential oils, generally considered as a waste product, were tested for their potential use as acaricides on V. destructor. Four hop varieties, namely Cascade, Spalt, Victoria, and Mapuche, showed an interesting performance as feasible products to be used in the beekeeping industry. Some volatile oxidized terpenoids were found in the hydrolats, mainly β-caryophyllene oxide, β-linalool, and isogeraniol. These compounds, together with the presence of polyphenols, flavonoids, and saponins, were probably responsible for the promissory LC50 values obtained for mites after hydrolat exposition. Victoria hydrolat was the most toxic for mites (LC50: 16.1 µL/mL), followed by Mapuche (LC50 value equal to 30.1 µL/mL), Spalt (LC50 value equal to 114.3 µL/mL), and finally Cascade (LC50: 117.9 µL/mL). Likewise, Spalt had the highest larval survival, followed by Victoria and Mapuche. Cascade was the variety with the highest larval mortality. In addition, none of the extracts showed mortality higher than 20% in adult bees. The Victoria hydrolat presented the best results, which makes it a good compound with the prospect of an acaricide treatment against V. destructor.

Abstract:

Plant remains from the Early Cretaceous of Victoria are described. These are leaves referred to Taeniopteris daintreei, female fructifications referred to Carnoconites cranwellii and microsporangiate structures herein described as Sahnia laxiphora sp. nov. These are considered to belong to the extinct group, the Pentoxylales, originally described from localities variously dated as Jurassic or Early Cretaceous in the Rajmahal Hills of India. It is suggested that the Pentoxylales, long regarded as an obscure group, are in fact a major and important part of the mid Mesozoic Gondwana flora in Victoria.

Full text

Abstract:

An outlier of mallee vegetation occurs south of the Great Dividing Range in Victoria in a rain shadow region (annual rainfall approx. 500 mm) about 50 km west of Melbourne. A Eucalyptus behriana open-scrub with a sparse understorey of chenopods, mosses, lichens and some grasses occurs on solonetz soil on lateritized Tertiary sandy clays and on skeletal soils on Ordovician slates and sandstones. The dryness of the mallee site is probably exacerbated by the smaller rate of water infiltration and greater salinity of the solonetz soil under E. behriana compared with the solodic soil, in the moister area further north, under an open-forest of E. microcarpa. The multistemmed habit of E. behriana appears to be partly genetically fixed. Hollow lignotuberous rings, filled to a depth of about 15-25 cm with brown, nutrient-rich humus, are common. Pattern analysis of the distribution of stems of E. behriana indicated strong clumping at about 9 m², due to the multistemmed habit, and weaker clumping at about 600 m², which correlated with the size of groups of dense, spindly individuals of E. behriana, resulting from a past phase of gap regeneration.

Full text

Abstract:

A population of Rattus fuscipes, in Sherbrooke Forest, Victoria, had a well defined breeding season. Mating occurred between November and January and the young were born between December and February. Juveniles were first captured in late February at approximately 1.5 months of age. The subadult age class displaced the parental age class in the population by the following August, so that almost all animals breeding in a season belonged to a single age class. The degree of home range overlap changed seasonally and could be related to changes in the proportion of amicable and agonistic behaviour judged from a series of contrived laboratory encounters. Diet consisted of both plant and insect material and changes in the proportion of these two components correlated with changes in survival. Measurements of 15 physiological parameters and organ weights, drawn at montly intervals indicated three periods during the life cycle when R. fuscipes exhibited heightened adreno-cortical activity. It is suggested that the development of territoriality in subadults during late autumn and possibly the decrease in abundance and quality of food in early winter, largely determine the size of the breeding population in late spring.

Full text

Abstract:

In the stringybark eucalypts, the baxteri clade consists of E. arenacea, from South Australia and northwestern Victoria, E. baxteri, mainly from the Great Dividing Range of Victoria, and E. alpina, an endemic taxon from the Grampian Ranges of Victoria. Populations of these taxa were sampled from across their geographic and morphological ranges. Phenetic and phylogenetic analyses were undertaken of the leaf volatile oil composition of the sampled plants. On the basis of these analyses, E. arenacea emerges as a cohesive, monophyletic species, while E. baxteri is a variable and probably paraphyletic species. Populations on Kangaroo Island, South Australia, are variable and intermediate, and may represent recent intergradation between the two species. Populations of E. baxteri from the Grampians are distinctive chemically, but not morphologically, within the species. Recent hybridisation between this form of E. baxteri and E. alpina was shown to be occuning within the Grampians. E. alpina is a highly variable taxon, and probably polyphyletic as currently recognised. Three distinct forms were recognised within E. alpina. The first, and most distinctive, is from the southern Serra Range; the second is from the northern Serra Range and Wonderland Range; the third, and most similar to E. baxteri, is from the Victoria Range.

Full text

Abstract:

The distribution, habitat preferences and population ecology of Pseudomys novaehollandiae in the Eastern Otways, Victoria, were studied from 1985 to 1989. The species has a patchy distribution and was captured at only four sites in heathy woodland-open forest. The population density of the species was low (0-3.1 ha-1) and the breeding season was from spring to summer. The vegetation on two trapping grids was classified into five floristic groups. Four small mammal species (Rattus lutreolus, Antechinus stuartii, Mus musculus and P. novaehollandiae) exhibited preferences for different floristic groups. There was evidence that P. novaehollandiae interacted, or competed, with M. musculus in one floristic group. Pseudomys novaehollandiae preferred two floristic groups which had high floristic diversity. Within these groups the species was associated with low dense vegetation cover. The decline of populations of P. novaehollandiae in this study is likely to be related to post-fire successional changes in the vegetation: either to loss of plant species diversity, or to loss of particular species or to low vegetation cover. Strategic burning of small areas within the preferred floristic vegetation is recommended to maintain a mosaic of suitable successional ages for the conservation of this endangered species.

Abstract:

Victoria Island in Canada’s western Arctic is the eighth largest island in the world and the second largest in Canada. Here, we report the results of a floristic study of vascular plant diversity of Victoria Island. The study is based on a specimen-based dataset comprising 7031 unique collections from the island, including some 2870 new collections gathered between 2008 and 2019 by the authors and nearly 1000 specimens variously gathered by N. Polunin (in 1947), M. Oldenburg (1940s–1950s) and S. Edlund (1980s) that, until recently, were part of the unprocessed backlog of the National Herbarium of Canada and unavailable to researchers. Results are presented in an annotated checklist, including keys and distribution maps for all taxa, citation of specimens, comments on taxonomy, distribution and the history of documentation of taxa across the island, and photographs for a subset of taxa. The vascular plant flora of Victoria Island comprises 38 families, 108 genera, 272 species, and 17 additional taxa. Of the 289 taxa known on the island, 237 are recorded from the Northwest Territories portion of the island and 277 from the Nunavut part. Thirty-nine taxa are known on the island from a single collection, seven from two collections and three from three collections. Twenty-one taxa in eight families are newly recorded for the flora of Victoria Island: Artemisia tilesii, Senecio lugens, Taraxacum scopulorum (Asteraceae); Crucihimalaya bursifolia, Draba fladnizensis, D. juvenilis, D. pilosa, D. simmonsii (Brassicaceae); Carex bigelowii subsp. bigelowii, Eriophorum russeolum subsp. albidum (Cyperaceae); Anthoxanthum monticola subsp. monticola, Bromus pumpellianus, Deschampsia cespitosa subsp. cespitosa, D. sukatschewii, Festuca rubra subsp. rubra, Lolium perenne, Poa pratensis subsp. pratensis (Poaceae); Stuckenia filiformis (Potamogetonaceae); Potentilla × prostrata (Rosaceae); Galium aparine (Rubiaceae); and Salix ovalifolia var. ovalifolia (Salicaceae). Eight of these are new to the flora of the Canadian Arctic Archipelago: Senecio lugens, Draba juvenilis, D. pilosa, Anthoxanthum monticola subsp. monticola, Bromus pumpellianus, Deschampsia cespitosa subsp. cespitosa, Poa pratensis subsp. pratensis and Salix ovalifolia var. ovalifolia. One of these, Galium aparine, is newly recorded for the flora of Nunavut. Four first records for Victoria Island are introduced plants discovered in Cambridge Bay in 2017: three grasses (Festuca rubra subsp. rubra, Lolium perenne, and Poa pratensis subsp. pratensis) and Galium aparine. One taxon, Juncus arcticus subsp. arcticus, is newly recorded from the Northwest Territories. Of the general areas on Victoria Island that have been botanically explored the most, the greatest diversity of vascular plants is recorded in Ulukhaktok (194 taxa) and the next most diverse area is Cambridge Bay (183 taxa). The floristic data presented here represent a new baseline on which continued exploration of the vascular flora of Victoria Island – particularly the numerous areas of the island that remain unexplored or poorly explored botanically – will build.

Abstract:

The habitats of existing populations of Thelymitra epipactoides in Victoria, Australia, are described according to the physical and biotic environments. The orchid is confined to a range of heathland communities usually near the coast. The species seems to prefer the more open, previously disturbed sites within the community. Following a discussion of the particular habitat requirements of T. epipactoides, some guidelines for the conservation management of the species are outlined.

Full text

Abstract:

The distribution and productivity of mangroves is directly affected by a wide range of climatic drivers, including temperature, frost, rainfall, evaporation and storm activity, which, in turn, influence a suite of secondary drivers, including changes in freshwater run-off and sediment supply, groundwater dynamics and inter-species competitiveness. The highest-latitude expression of mangroves globally is at Millers Landing, Victoria (38°45′S), and because the vigour and productivity of mangroves across much of Victoria is thought to be limited by low winter temperatures and the incidence and severity of frosts, it is likely that mangroves will be among the first plant communities to be affected by climate change in coastal south-eastern Australia. An increase in plant vigour is likely, but there are almost no historical data with which to compare current rates of primary production. An extension of mangroves to higher latitudes on the mainland is impossible because of the geomorphology of the land that lies further to the south. Small-scale changes in distribution, including the progressive encroachment of mangroves into coastal saltmarsh, are likely to be among the clearest indications of the response of mangroves to a warming climate. Increased effort into tracking changes in mangrove vigour, productivity and distribution is clearly warranted.

Abstract:

Bryophytic communities in plateau forests of mature Eucalyptus regnans are distributed according to substrate type and microclimate, whereas those in gully rainforests are more catholic. Objective classification of releves indicated the extent to which groupings are shared between these major topographic sites and the degree to which their distribution is mediated by differences in microclimate. Communities on many substrates in E. regnans forests are either seral to a fern floor 'climax' or exhibit pattern and process cycles of regenerative stability.

Abstract:

A morphometric study of the Olearia phlogopappa species complex from throughout south-eastern Australia has confirmed species boundaries and resolved the infraspecific taxonomy of two species. It has shown O. phlogopappa (Labill.) DC., O. stellulata (Labill.) DC., O. lirata (Sims) Hutch., O. rugosa (F.Muell. ex W.Archer bis) Hutch. and O. brevipedunculata N.G.Walsh to be non-overlapping entities with unique morphological characters. O. stellulata is circumscribed to include only southern and western Tasmanian populations and those from the Otways and Wilsons Promontory in southern Victoria. O. rugosa is restricted to Victoria and a few isolated populations on Flinders Island and northern Tasmania. Four previously noted variants of O. rugosa from Victoria are here described as subspecies, along with the description of a fifth subspecies from northern Tasmania. Infraspecific boundaries of O. phlogopappa are here revised to include nine subspecies, six of which were previously included as varieties, and descriptions are made of three new subspecies.

Australian Journal of Botany 59, no. 3 (2011): 207. http://dx.doi.org/10.1071/bt10197.

Full text

Abstract:

Toothed Leionema is one of four subspecies of Leionema bilobum from the Rutaceae family. A dense shrub or small tree, growing to ~4 m high, it is a poorly investigated species which is considered rare in Victoria, Australia. This paper presents the results of a study using Geographical Information Systems and Weights-of-Evidence predictive modelling to assess the importance of seven environmental factors in determining habitat suitability for this species in the Strzelecki Ranges, Victoria. This method is particularly useful in understanding the distribution of rare species, especially where the ecology of the species of interest is not well understood. Of the seven environmental factors considered here, four were found to be important: elevation, aspect, distance to water and distance to plantation (disturbed) areas. The modelling results indicate that areas with elevations between 350 and 550 m and a dominant south-western aspect that are close to plantation areas (within 700 m), and to water (within 1100–1200 m), provide potentially suitable habitat for Toothed Leionema in the region.

Full text

Abstract:

AbstractThe Jurassic plant fossil record of Gondwana is generally meagre, which renders phytogeographic and palaeoclimatic interpretations difficult to date. Moreover, plant fossil assemblages mainly consist of impressions/compressions with rather limited palaeobiological and palaeoecological significance. We here present a detailed survey of new Early Jurassic plant assemblages from the Pliensbachian Shafer Peak Formation, north Victoria Land, Transantarctic Mountains. Some of the well-preserved fossils yield cuticle. The floras consist of isoetalean lycophytes, sphenophytes, several ferns, bennettitaleans, and conifers. In addition, three distinct kinds of conifer shoots and needles were obtained from bulk macerations. The composition of the plant communities is typical for Jurassic macrofloras of Gondwana, which underscores the general homogeneity of Southern Hemisphere vegetation during the mid-Mesozoic. Altogether, the plant fossil assemblages indicate humid and warm temperate conditions, which is in contrast to recent palaeoclimatic models that predict cool temperate climates for the continental interior of southern Gondwana during the Jurassic. However, there is no evidence for notable soil development or peat accumulation. The environmental conditions were apparently very unstable due to intense volcanic activity that resulted in frequent perturbation of landscape and vegetation, hampering the development of long-lived climax communities. Cuticles of bennettitaleans and conifers show xeromorphic features that may have been beneficial for growth in this volcanic environment.

Full text

Abstract:

Specimens of Phebalium glandulosum Hook. subsp. glandulosum representing the entire geographic range of the subspecies were examined for morphological and anatomical variation. Phenetic patterns were identified with the pattern analysis package PATN, and three distinct groups were identified. One group consists of plants from inland areas of New South Wales, north-western Victoria, and the Yorke and Eyre Peninsulas of South Australia; a second group consists of plants collected from alongside the Snowy River in eastern Victoria and south-eastern New South Wales; and a third group consists of plants from Queensland and northern New South Wales. The climate analysis program BIOCLIM was used to compare climate variables across the geographic range, and showed clear climatic separation in support of the phenetic analysis. The three groups are formally recognised here as distinct subspecies. Plants from Queensland and the Bourke region of northern New South Wales belong to the typical subspecies; plants from north-western Victoria, central New South Wales, and the Yorke and Eyre Peninsulas of South Australia form a cohesive assemblage and are recognised as a new subspecies P. glandulosum subsp. macrocalyx; and plants from the Snowy River in far eastern Victoria and the Southern Tablelands of New South Wales form a distinct and isolated group recognised as a new subspecies P. glandulosum subsp. riparium. These new subspecies are formally described, and an identification key and summaries distinguishing all six subspecies of P. glandulosum are presented.

Full text

Abstract:

The complete geographic range of Eucalyptus nitens s. lat. (shining gum) was sampled to determine the pattern of variation in adult and seedling morphology. Analyses of the different data sets indicated the presence of two distinct taxa: one, characterised by denticulate adult leaf margins, is described as E. denticulata sp. nov.; the other, characterised by entire leaf margins, is E. nitens s. str. Many other characters distinguish the two taxa. Mature trees of E. denticulata have leaves with higher oil gland density, longer peduncles, more cup-shaped rather than barrel-shaped fruit, more frequently exserted valves, and rounded and longer flower buds compared with E. nitens s. str. Seedlings of the two species can be distinguished mainly on the basis that those of E. denticulata have longer internodes and leaves which clasp the stem to a lesser extent. The major occurrence of E. denticulata is on the Errinundra Plateau, East Gippsland, with limited occurrences in the Baw Baw Ranges and Central Highlands of Victoria. Eucalyptus nitens s. str. is found in isolated stands in New South Wales and Victoria. The two species are allopatric, with the exception of the Baw Baw Ranges and Central Highlands of Victoria where some stands are mixed. Eucalyptus nitens s. str. is also geographically variable, comprising three distinct geographic races: northern and central New South Wales, southern New South Wales, and the Baw Baw Ranges and Central Highlands of Victoria.

Abstract:

Three species of pipefish, Urocarnpus carinirostris Castelnau, Vanacarnpus phillipi (Lucus) and Mitotichthys semistriatus (Kaup), occurred regularly in collections from eelgrass beds of Western Port. A fourth species, Stigmatopora nigra Kaup, was rare. U. carinirostris and V. philippi dominated catches. Brooding males were present for 6-9 months of the year, juveniles were recruited in summer and early autumn, and both species were annual. The pipefish fauna included two main behavioural types. V. phillipi and M. sernistriatus oriented themselves horizontally and were relatively strong swimmers. U. carinirostris and S. nigra were more sedentary, attaching themselves to benthic vegetation by means of a prehensile tail. The latter two species closely mimicked eelgrass leaves in movements, orientation and colour. All inhabited the eelgrass leaf canopy except V. phillipi, which occupied the sediment-water interface. The pipefish were visually orienting, sit-and-wait predators. Pelagic or epibenthic copepods and small epibenthic amphipods comprised the bulk of diets; only V. phillipi ingested polychaetes and plant detritus.

Full text

Abstract:

The native grassland of the Victorian Volcanic Plain, in south-western Victoria, Australia, is a critically endangered community. Much of the remaining grassland exists on private land, where it is grazed by livestock. The impacts of two grazing management strategies, implemented under the PlainsTender incentive scheme, were monitored at 18 on-farm native grassland sites for 4 years. The management strategies were (1) excluding grazing during spring, or (2) flexible grazing and resting. Maintenance of >70% vegetation cover was required under both strategies. Generalised least-squares (repeated-measures) modelling revealed a significant correlation between plant functional group cover and management. However, this correlation was present at the outset of the study and was maintained for the duration of monitoring. Sites rested from livestock grazing in spring had higher native and exotic grass cover, while exotic forb cover was higher at sites where grazing was managed flexibly. Native and exotic grass cover varied significantly from year-to-year under both management strategies; we attribute this to variation in rainfall, particularly drought in the second year. A key outcome of this study was the recognition that high conservation value native grasslands, i.e. large (≥100 ha) and intact (≥36 native species), are being managed successfully on private land, using a range of conservative livestock grazing strategies.

Full text

Abstract:

The charophytes (Charales, Charophyta) from south-eastern South Australia and south-western Victoria were studied on the basis of collections from 56 waterbodies, 39 of which included charophytes. Chara globularis var. globularis (Thuillier) Wood, C. globularis var. virgata (KÜtzing) Wood, C. fibrosa var. fibrosa (Agardh ex Bruzelius) Wood, C. fibrosa var. acanthopitys (Braun) Wood, C. hookeri Braun, C. preissii (Braun) Wood, Lamprothamnium macropogon (Braun) Ophel, Nitella ignescens García, N. ungula García, N. lhotzkyi (Braun) Braun, N. aff. lhotzkyi, and N. congesta (Brown) Braun were recognised. An identification key for these species makes determination possible. A brief characterisation of the environment where the charophytes were found is provided, as a first approximation of the ecological requirements of Australian charophytes. At this stage their distribution can be mainly related to salinity, with charophytes living in fresh to hypersaline conditions (0.0–58.0 g L–1). Special attention is put on L. macropogon, a euryhaline calcifying species, which has the broadest distribution in the area. The floristic analysis shows endemism, dioecism and a high diversification of non-calcifying taxa as the main characteristics of the charophyte flora analysed.

Abstract:

Abstract— Reinterpreting the morphology of two taxa proposed by Victoria C. Hollowell in the 1980s and not formally published, we describe here three new species of Eremitis, a Neotropical genus of herbaceous bamboos (Poaceae, Bambusoideae, Olyreae), which is endemic to the Brazilian Atlantic Forest. Two of them, Eremitis grandiflora and E. paucifolia, are endemic to Espírito Santo state. Eremitis victoriae occurs in southern Espírito Santo and has also been documented for southern Bahia. Eremitis grandiflora is similar to the smallest species of the genus, but can be differentiated by its decumbent culms with scale-like leaf blades and its longer gynecandrous whorls. Eremitis paucifolia is characterized by its leafy culms with a reduced number of leaves [5‐6(‐7)] compared to other species of the genus. Eremitis victoriae is distinguished from the congeneric species mainly by its abaxially glaucous leaf blades. Here, we provide an identification key to all described species of Eremitis that occur in Espírito Santo, as well as a map with their geographical distribution. All three new species are illustrated with both line drawings and photographic images, and an informal assessment of their conservation status is presented.

Abstract:

Cover and luxuriance of plant species in the alpine grassland community were measured. Four grassland sites were monitored regularly from 1979 to 1984; three are grazed during summer months by free-ranging cattle, the other has not been grazed since 1974. Data are presented for cover of major species at another grazed site monitored since 1947. Three classes of total vegetation cover were defined in relation to the susceptibility of a site toerosion. Results show that there have been no trends in vegetation cover and luxuriance. Species composition and total vegetation cover varied between sites but there were no dis- cernible trends in these characteristics.

Full text

Abstract:

Seasonal variations in starch and soluble sugar in root wood of standing trees and stumps of messmate stringybark (Eucalyptus obliqua) and Victorian blue gum (E. globulus subsp. bicostata) were measured for 2 years in four mature stands at Mount Cole, Victoria. Previously established seasonal variations were confirmed for E. obliqua standing trees, and similar patterns were established for E. globulus subsp. bicostata in the first year of the study. E. globulus subsp. bicostata had higher starch reserves but similar sugar reserves to E. obliqua. Selection, shelterwood and clearcutting at the beginning of the second season had no effect on the starch and sugar reserves of retained trees. However, starch levels for stumps declined and appeared to be converted to sugars as the latter were maintained at normal levels, and they continued to show a seasonal variation for at least 12 months after cutting. There is little or no scope for manipulating the food base for Armillaria by varying the harvesting treatment and/or the season of treatment.

Full text

Abstract:

An Early Eocene plant assemblage from near the summit of Mt Hotham, Victoria, is described, using a combination of macro- and microfossils, especially cuticles. This is important since no other Australian macrofossil sites from this time, when environmental conditions are believed to have been the warmest of the Cenozoic, have been described in detail. The nature of the flora and vegetation supports geological evidence that the site was upland (approximately 800 m above sea level) at this time, with climatic conditions similar to those now experienced in regions such as the Atherton Tablelands in Queensland and mid-montane Papua New Guinea. The vegetation was probably a form of rainforest dominated by mesotherm elements, with abundant ferns including Gleicheniaceae and the tree ferns Cnemidaria, Cyathea and Dicksonia. Gymnosperms included Araucariaceae (Agathis) and Podocarpaceae (at least Acmopyle and Dacrydium). Angiosperms were diverse in Lauraceae (at least nine species including probably Cryptocarya, Endiandra and Litsea) and Proteaceae (at least nine species including probably Musgravea and Darlingia). Other angiosperms included Cunoniaceae, Gymnostoma (Casuarinaceae), Diospyros-like Ebenaceae, and the vine Cissocarpus (Vitaceae). Nothofagus was rare or absent from the Mt Hotham region at this time, as no macrofossil evidence was found, and pollen percentages were very low.

Australian Systematic Botany 23, no. 6 (2010): 387. http://dx.doi.org/10.1071/sb10028.

Full text

Abstract:

The fern Asplenium hookerianum Colenso (Aspleniaceae) is indigenous to New Zealand and Australia. In New Zealand, it is widespread and genetically diverse, with 26 haplotypes previously identified for the chloroplast trnL–trnF locus. In Australia, A. hookerianum is currently known only from two small populations in Victoria and two in Tasmania. The present study assessed the diversity, relationships and biogeographic history of the Australian populations. A single trnL–trnF haplotype was identified in Tasmanian populations, and it was shared with populations in south-western New Zealand. The single haplotype found in Victorian populations was unique and most similar to a haplotype found in populations from central and eastern North Island, New Zealand. Relationships among haplotypes suggest that the two Australian haplotypes are derived within the group (not close to the root of the haplotype network) and only distantly related. This pattern is consistent with two independent dispersals of A. hookerianum from New Zealand to Australia. These findings are unique in providing evidence for more than one trans-Tasman dispersal event in a species of vascular plant.

Full text

Abstract:

The vertebrate fauna of broombush Melaleuca uncinata vegetation in north-western Victoria was assessed by censusing in marked quadrats, trapping and wide-ranging observations. Most species of vertebrates known to occur in mallee shrublands in Victoria we recorded in broombush (those recorded included four amphibian, 42 reptile, 126 bird and 18 mammal species). This high diversity resulted from a substantial variation in vertebrate (particularly reptile and bird) species composition between broombush of differing ages (0-80 years). Some floristic variation between broombush stands and the local presence within these stands of particular plant species (notably Triodia irritans and Banksia ornata) also added to vertebrate species diversity. Locally, broombush patches were characteristically simple in structure and of low floristic diversity. Bird species diversity and density were low (<3 individuals per ha). Broombush is being harvested at an accelerating rate in Victoria. The effects of this industry on vertebrates generally are minor. No vertebrate species is restricted to broombush, and most vertebrate species recorded in this survey were found in harvested areas. Nonetheless, broombush is an important habitat for several species (e.g. Ctenophorus pictus, Ctenotus uber, C. brooksi, Leipoa ocellata, Pachycephala rufogularis, Psophodes nigrogularis, Drymodes brunneopygia, Cercartetus lepidus and Notomys mitchelli). Information on the ecology of most species of vertebrates living in the mallee is very limited, and some species may be affected by broombush cutting through a decrease in area of habitat of suitable age.

Abstract:

Fossil conifers from an early Miocene flora at Balcombe Bay near Melbourne, Australia, are described and illustrated. The most prominent elements are Araucaria balcombensis Selling emend. R.S.Hill and Dacrycarpus mucronatus P.M.Wells & R.S.Hill, and several other unidentified podocarp leaves are represented. Ovuliferous cones of D. mucronatus are described, along with isolated araucarian microsporophylls and podocarp pollen cones – both with pollen in situ. The floristic elements are similar to Eocene–Oligocene flora described from Tasmania, and indicate that these floras extended to now mainland Australia and persisted into the Miocene. They are indicative of a wetter and warmer climate than the present time.

Abstract:

Singidia Tilapia Oreochromis esculentus is a Critically Endangered native tilapia fish species endemic to lakes Victoria and Kyoga basins of East Africa, however, it disappeared from these main lakes due to overfishing, environmental degradation and predation by the introduced Nile Perch Lates niloticus. Remnant populations of this fish species is now restricted to satellite lakes including Lake Kayanja of the Victoria basin. This study provides updated information about the population abundance, critical habitat, threats and diet of Singidia Tilapia to inform conservation decisions to revive its populations in the wild. Fish data collection and mapping of nursery and breeding habitats of Singidia Tilapia on Lake Kayanja was conducted between February 2016 and October 2017. In all the areas mapped and sampled, Singidia Tilapia (with a size range of 11–27 cm TL) was the most abundant (43%) relative to exotic Nile Tilapia Oreochromis niloticus (21%) and Redbelly Tilapia Coptodon zillii (36%). The emergence of introduced (exotic) tilapias like Nile Tilapia recorded in this study could be attributed to cage fish farming being carried out in this Lake. The diet of Oreochromis esculentus consisted mainly of detritus (60.8 %), plant materials (27.7%) and blue-green algae (5.5%). Destruction of critical habitats and presence of introduced fish species were noted as the major threats to this fish and its habitats. The generated information could contribute to guiding stakeholders to undertake appropriate actions to conserve this threatened fish species and its habitats.

Abstract:

The effects of two operational nursery fertilization regimes on the growth and nutrient dynamics of Douglas-fir ( Pseudotsuga menziesii var. glauca (Beissn.) Franco) seedlings after planting were compared. Seedlings were grown in a nursery with nutrients added at a constant rate (conventional fertilization) or at a rate that increased exponentially by 2%·day–1 (exponential fertilization) and planted near Barriere and Victoria, British Columbia. At the time of planting, half of the conventionally fertilized seedlings were planted with slow-release fertilizer packets. Growth and nutrient allocation was observed for 2 years following planting. Although the exponential fertilization regime provided 25% more N in the nursery compared with the conventional fertilization regime, exponentially fertilized seedlings were smaller at the time of planting, did not differ significantly in foliar N concentration, and showed no lasting benefits in growth or nutrient allocation. Two years after planting, there were no significant differences between the conventional and exponential fertilization regimes in seedling height, root collar diameter, total dry mass, or whole-plant N concentration. Seedlings fertilized at the time of planting had greater height and dry mass on the Barriere site but not on the dry Victoria site and whole-plant N concentrations did not differ 2 years after planting.

Full text

Abstract:

Abstract In flowers of Nymphaea and Victoria, carpellary appendages are regarded as structures related to pollination by deceit of night-blooming species. In this study, the anatomy, histochemistry and ultrastructure of carpellary appendages were analysed to investigate their possible role in the production of volatile compounds in nocturnal species Nymphaea amazonum, N. gardneriana, N. prolifera (Nymphaea subgenus Hydrocallis) and Victoria cruziana, and in diurnal species N. caerulea (Nymphaea subgenus Brachyceras). Carpellary appendages were studied using light microscopy and scanning and transmission electron microscopy from pre-anthesis to the second day of anthesis. Anatomical and ultrastructural features are characteristic of osmophores. In all species, the most frequent components in secretory cells are amyloplasts, lipid bodies, mitochondria, rough endoplasmic reticulum and elaioplasts. The epidermis and multilayered parenchyma accumulate abundant starch grains and lipophilic substances, both of which vanish during anthesis. Amorphous substances are deposited between the plasmalemma and the outer cell wall of epidermal cells, and are then released by cuticular diffusion. Odour production in carpellary appendages might be an ancient role of primary importance both in diurnal and nocturnal species that are pollinated by deceit. Olfactory and visual cues of small carpellary appendages in Nymphaea subgenus Brachyceras correspond to bee pollination, and large carpellary appendages in subgenus Hydrocallis and Victoria represent parallel functional specializations of the flowers to the attraction and reward for exclusive beetle pollination.
