Testo completoAbstract (sommario):
To resolve the relationships of taxa within the Beaufortia suballiance (Myrtaceae), 72 ingroup taxa were analysed by parsimony methods and nrDNA sequence data from the 5S and ITS-1 ribosomal DNA spacer regions. Although basal nodes in the consensus tree (combined data set) are not supported by bootstrap or jackknife values, a number of clades are well supported, showing that Melaleuca is polyphyletic. Monophyletic groups include: endemic species of Melaleuca from New Caledonia (including species of Callistemon recently transferred to Melaleuca); the tropical Melaleuca leucadendra group; Australian species of Callistemon, which relate to species of Melaleuca predominantly from the South-East; and a group of south-western and eastern Australian melaleucas that relate to a clade of three south-western genera, Eremaea, Conothamnus and Phymatocarpus. Calothamnus, Regeliaand Beaufortiamay also relate to this latter group. Lamarchea is possibly related to northern melaleucas. The results have implications for generic revisions of the large genus Melaleuca. Biogeographic subtree analysis, based only on supported nodes of the taxon cladogram, showed New Caledonia, New Guinea, Eastern Queensland and the Northern Desert unresolved at the base of the area cladogram. The position of some of these areas is likely to be artifactual, but New Caledonia is interpreted as in the correct position. At a higher node, the monsoonal northern areas of Australia (Kimberley, Arnhem and Cape York), Atherton, the Pilbara and Western Desert relate to the southern regions, which form a group. The South-West of Australia is related to Eyre and Adelaide (designated area ‘South’) and Tasmania is related to the South-East and MacPherson–Macleay. The vicariance between northern and southern regions in Australia possibly relates to an early major climatic change (from the Early Tertiary). The biogeographic analysis helped illuminate taxon relationships.

Marine and Freshwater Research 59, n. 3 (2008): 187. http://dx.doi.org/10.1071/mf07072.
Testo completoAbstract (sommario):
Over the past 40–50 years, the woody shrub Melaleuca ericifolia has progressively invaded large areas of Phragmites australis in Dowd Morass, a Ramsar-listed, brackish wetland in south-eastern Australia. To understand the processes underlying this shift we grew Phragmites and Melaleuca alone and together under contrasting sediment organic-matter loadings and salinities. To examine if the capacity of Phragmites to aerate the sediment influenced plant interactions, we also dissipated convective gas flow in some Phragmites plants by perforating their stems. Although Phragmites suppressed the growth of Melaleuca under all conditions, Melaleuca persisted. We did not find Phragmites ramets to be more sensitive to salinity than Melaleuca seedlings. Surprisingly Phragmites did not increase sediment redox and was more sensitive to increased organic-matter loading than Melaleuca. These results do not support the notion that colonisation by Melaleuca was facilitated by a decline in Phragmites at higher salinities or through aeration of the sediments by Phragmites. Seedlings of Melaleuca, however, were easily blown over by wind and it is likely that Phragmites stands shelter Melaleuca during establishment. Although our short-term experiment did not show that Melaleuca was a better competitor, differences in seasonal growth patterns may contribute to a shift in competitive abilities over a longer time scale.

Testo completoAbstract (sommario):
Gallery and floodplain forests in monsoonal northern Australia are mostly sclerophyllous and dominated by five closely related species of Melaleuca (Myrtaceae) amongst which niche differentiation is unclear. We present a floristic and environmental analysis of ‘the flooded forest’ using data from 340 plots distributed across 450 000 km2 of the Top End of the Northern Territory. Melaleuca argentea was confined to streams and occurred on sandier substrates, whereas M. cajuputi mostly occurred in the near-coastal lowlands on clay soils. The greater basal area of M. cajuputi suggests an association with productive sites. Melaleuca dealbata, M. viridiflora and M. leucadendra occurred on a wide range of soils. More deeply floodprone sites were occupied by M. argentea and M. leucadendra along streams and by M. leucadendra and M. cajuputi on floodplains and in swamps. A general deficiency but occasional abundance of Melaleuca seedlings suggests that regeneration is episodic. Seedlings were more frequent in recently burnt areas and especially where fires had been severe. We propose that Melaleuca forests occur where disturbance by fire and/or floodwater is too great for rain forest to persist, rendering them the wetland analogue to the eucalypts that dominate well-drained portions of the north Australian environment.

Testo completoAbstract (sommario):
Involvement of Indigenous people and knowledge in conservation science has become a clear directive in international covenants. Currently, approximately one-third of Australia is owned and managed by Indigenous people, including 84% of the Northern Territory coastline, making Indigenous-led and cross-cultural research highly relevant. Recently, the Yolŋu Senior Knowledge Custodians of the Laynhapuy Indigenous Protected Area in northern Australia expressed concern about the dieback of culturally significant coastal Melaleuca (paperbark) stands. A partnership between Senior Knowledge Custodians and Western scientists was used to develop an ecocultural research framework to investigate the dieback. Semistructured interviews about the likely causes were conducted with Senior Knowledge Custodians of five coastal flood plain sites where dieback occurred. At these sites, comparative ecological assessments of paired dieback and healthy Melaleuca stands were conducted to explore relationships between Melaleuca stand health, salt water intrusion, acid sulfate soils and feral ungulate damage. Melaleuca dieback was observed in three species: nämbarra (M. viridiflora), raŋan (M. cajuputi) and gulun’kulun (M. acacioides). The sociocultural and ecological research approaches similarly suggested that ~70% of Melaleuca spp. dieback was attributed to combinations of salinity and feral ungulate damage. An ecocultural approach heightened understanding of Melaleuca dieback because we detected similarities and differences in likely causal factors.

Testo completoAbstract (sommario):
Rhizanthella gardneri R.S.Rogers is an entirely subterranean mycoheterotrophic orchid known only from two isolated populations within south-western Western Australia (WA). This rare species appears restricted to habitats dominated by species of the Melaleuca uncinata complex. R. gardneri purportedly forms a tripartite relationship with Melaleuca1, via a connecting mycorrhizal fungus, for the purpose of carbohydrate and nutrient acquisition. Here, we quantify key climate, soil and vegetation characteristics of known R. gardneri habitats to provide baseline data for monitoring of known R. gardneri populations, to better understand how R. gardneri interacts with its habitat and to identify possible new sites for R. gardneri introduction. We found that the habitats of the two known R. gardneri populations show considerable differences in soil chemistry, Melaleuca structure and Melaleuca productivity. Multivariate analyses showed that both multidimensional scaling (MDS) and principal components analysis (PCA) ordinations of soil chemical characteristics were very similar. Individual sites within populations were relatively similar in all attributes measured, whereas overall northern and southern habitats were distinct from each other. These results suggest that R. gardneri can tolerate a range of conditions and may be more widespread than previously thought, given that there are extensive areas of Melaleuca thickets with similar habitat characteristics across south-western WA. Variability within the habitats of known R. gardneri populations suggests translocation of this species into sites with similar vegetation may be a viable option for the survival of this species.

Testo completoAbstract (sommario):
Psyllids, also known as jumping plant lice, are phloem feeding Hemiptera that often show a strict species-specific relationship with their host plants. When psyllid-plant associations involve economically important crops, this may lead to the recognition of a psyllid species as an agricultural or horticultural pest. The Australian endemic tea tree, Melaleuca alternifolia (Maiden & Betche) Cheel., has been used for more than a century to extract essential oils and, long before that, as a traditional medicine by Indigenous Australian people. Recently, a triozid species has been found to damage the new growth of tea trees both in Queensland and New South Wales, raising interest around this previously undocumented pest. Furthermore, adults of the same species were also collected from Citrus plantations, leading to potential false-positive records of the exotic pest Trioza erytreae (Del Guercio 1918), the African Citrus psyllid. Here we describe for the first time Trioza melaleucae Martoni sp. nov. providing information on its distribution, host plant associations and phylogenetic relationships to other Trioza species. This work enables both morphological and molecular identification of this new species, allowing it to be recognized and distinguished for the first time from exotic pests as well as other Australian native psyllids. Furthermore, the haplotype network analysis presented here suggests a close relationship between Trioza melaleucae and the other Myrtaceae-feeding Trioza spp. from Australia, New Zealand, and Taiwan.

Testo completoAbstract (sommario):
The genus Melaleuca is native to Australia, with about 250 species spread from favourable to very stressful ecological habitats. We analysed the leaves of 125 Melaleuca species for the accumulation of proline analogues to explore relationships between the ability of the species to accumulate proline analogues and their ability to adapt to various stressful habitats in Australia. Melaleuca species that have evolved the ability to accumulate only L-proline seem to be adapted to non-saline or non-sodic soils in regions of higher rainfall. Species that accumulate N-methyl-L-proline seem to be adapted to saline and/or sodic soils with moderate amount of rainfall. Species that accumulate trans-4-hydroxy-N-methyl-L-proline seem to be adapted to saline and/or sodic soils and occur in areas with considerably lower rainfall, while species that accumulate trans-4-hydroxy-N,N-dimethyl-L-proline are widely distributed in Australia, with a particular adaptation to extremely arid (deserts) and saline and/or sodic soils. The species accumulating more than one osmoprotectant seem to have an ecophysiological advantage over plants accumulating only one osmoprotectant.

"A comparison of tree water use in two contiguous vegetation communities of the seasonally dry tropics of northern Australia: the importance of site water budget to tree hydraulics". Australian Journal of Botany 55, n. 7 (2007): 700. http://dx.doi.org/10.1071/bt07021.
Testo completoAbstract (sommario):
Tree water use in two contiguous communities (eucalypt open-forest and Melaleuca paperbark forest) was measured in tropical Australia, over a 2-year period. The aims of the study were to (1) quantify daily and seasonal patterns of water use in each community, (2) compare patterns of water use among the communities and (3) compare relationships among tree size, sapwood area and water use within the two contrasting vegetation communities. Access to deep soil water stores and the effect of run-on from the eucalypt forest resulted in a relatively high pre-dawn water potential throughout the year, particularly for Melaleuca forest. There were no differences in daily rates of water use, expressed on a sapwood area (Q s) basis, between the two eucalypt species examined (Eucalyptus miniata Cunn. Ex Schauer and E. tetrodonta F.Muell) at any time in the eucalypt forest. For both the eucalypt and Melaleuca forests, there was less seasonal variation in water use expressed on a leaf area (Q l) basis than on a Q s basis, and neither year nor season were significant factors in Q l. In the mono-specific Melaleuca forest, Q s was not significantly different between years or seasons. Water use on a Q l basis was similarly not significantly different between years or seasons in the Melaleuca forest. Leaf area index (LAI) of the eucalypt forest was about half of that of the Melaleuca forest throughout the year but sapwood area per hectare was 33% larger in the eucalypt than the Melaleuca forest, despite the basal area of the Melaeuca forest being almost double that of the eucalypt forest. There was no significant difference in stand water use (mm day–1) between eucalypt and Melaleuca forests during 1998; however, in 1999 Melaleuca stand water use was larger than that of the eucalypt forest. Because of the enhanced dry-season availability of water in the Melaleuca forest and its larger LAI, average annual water use of the Melaleuca forest was almost 60% larger than that of the eucalypt forest. Despite differences in Q l, Q s and annual water use between forests, the ratio of LAI to stand water use was similar for all seasons in both forests. The applicability of ‘universal rules’ linking tree water use and tree hydraulics and the importance of ecosystem location on site water budgets and plant adaptations are discussed.

This study was carried out in a woodland on the campus of University of Western Sydney at Richmond, Australia to investigate seasonal effects and recovery speed of arboreal arthropods after disturbance. Twenty one pairs of Melaleuca linariifolia Sm. trees were sampled using insecticide spraying in a log2 nine period sequence (1-32) of weeks supplemented by additional samples to incorporate seasonal (weeks 24 and 48) and annual (week 52) samples. Using species accumulation curves, it was found that four collectors provided a reasonable representation of a tree's fauna and that a single tree does not provide a representative sample of the arthropod fauna found on trees of this species in the study area. The application of richness and evenness indices in different seasons showed significant changes in diversity. It was clear from the findings of the study that careful attention needs to be paid to experimental design. Under replication is the normal situation in previous studies and the effects of location, season and disturbance are all critical factors affecting the estimation of diversity.Doctor of Philosophy (PhD)

Thesis, SOAS, University of London, 1997. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.245216.
Testo completoAbstract (sommario):
In the past fire ecology literature in the tropics has focused mostly on the role of fire within the savanna biome. The fire ecology of tropical wetlands has been largely neglected. This thesis attempts to redress this imbalance by examining the fire behaviour of the wetlands in Kakadu National Park, northern Australia. Wetland burning has become a critical management issue in the Park, particularly since the eradication of the feral Asian water buffalo (Bubalus bubalis Linnaeus) from the Park. Fuel loads, which had been previously suppressed by grazing and trampling, have increased substantially, and this has subsequently affected the fire ecology of the region. This thesis investigates aspects of fire ecology in the Mclaleucafloodplain communities of Kakadu. It examines Aboriginal people's contemporary use and knowledge of fire, as well as the fire behaviour and impact of fires both set by Aboriginal people and from other sources of ignition. In addition, a 'Wetland Burning Index' (WBI) is compiled in order to examine some of the interactions between wetland fuel, weather and fire behaviour. A range of ecological and ethnoecological methodologies are employed in order to measure fire behaviour in situ rather than approximating specific fire regimes under experimental conditions. The thesis assesses the effectiveness and practicability of these methods. A description of wetland fire behaviour is also given, and includes a range of fire types and phenomena. Aboriginal names of fires, and related terms, are also detailed (in the Gundjeihmi language), some of which have not been previously documented. The study concludes by discussing how indigenous people's knowledge of fire can contribute to the field of wetland fire ecology. It also discusses how different fire types can be used to manage tropical wetland ecosystems.

Testo completoAbstract (sommario):
Rhizanthella gardneri (Rogers) is a critically endangered orchid restricted to two isolated regions of south-western Australia. Rhizanthella gardneri is an entirely subterranean mycoheterotrophic species that purportedly forms a tripartite relationship with a mycorrhizal fungus (Ceratobasidiales) that links with an autotrophic shrub of the Melaleuca uncinata complex to acquire nutrients. Whether the rarity of R. gardneri is intrinsic is overshadowed by the recent effect of extrinsic factors that means R. gardneri requires some form of conservation and may also be a viable candidate for restoration. To create an integrated conservation strategy for R. gardneri, reasons for its decline and knowledge of its biological and ecological functioning must be elucidated. This thesis focuses on three key questions; 1) what are the habitat requirements and limitations to R. gardneri survival; 2) what is the identity and specificity of the fungus R. gardneri forms mycorrhizas with; and 3) does R. gardneri form a nutrient-sharing tripartite relationship with a mycorrhizal fungus and autotrophic shrub. Key climate, soil and vegetation characteristics of known R. gardneri habitats were quantified to provide baseline data for monitoring known R. gardneri populations, to better understand how R. gardneri interacts with its habitat, and to identify possible new sites for R. gardneri introduction. Habitats of the two known R. gardneri populations differed considerably in soil chemistry, Melaleuca structure and Melaleuca productivity. Individual sites within populations were relatively similar in all attributes measured while overall Northern and Southern habitats were distinct from each other. These results suggest that R. gardneri can tolerate a range of conditions and may be more widespread than previously thought, given that there are extensive areas of Melaleuca thickets with similar habitat characteristics across south-western Australia. The fungus forming mycorrhizas with R. gardneri was identified, using nuclear ribosomal DNA sequences, as a Rhizoctonia-type fungus within the Ceratobasidiales. All fungi isolated from R. gardneri individuals representative of its currently known distribution were genetically similar, suggesting R. gardneri is highly dependent on this specific fungal species. Given that R. gardneri appears to exclusively associate with a specific fungal species, species-specific molecular primers were designed and used to analyse the fungis presence in known and potential R. gardneri habitats. These results 6 suggest that the fungus exists beyond the known R. gardneri habitats and gives hope to finding new populations.

Uddin, Md Nazim. "Ecological implications of allelopathic interferences with reference to Phragmites australis". Thesis, 2014. https://vuir.vu.edu.au/25791/.
Testo completoAbstract (sommario):
The effects of plant invasions on ecosystem structure and function are well studied but the pathways and mechanisms that underlie these effects remain poorly understood. In depth investigation of invasion mechanisms is vital to understanding why invasive plants impact only certain systems, and why only some invaders have disproportionately large impacts on the invaded community. There are many mechanisms such as lack of natural enemies or control mechanisms, the individual characteristics of the invader and invaded communities, direct and indirect resource competition, evolution or hybridisation, altered ecosystems processes, and allelopathy that may explain the invasion processes of plant species. Among these possible influences on invasion, allelopathy has received increased attention and study with the rise in understanding of its implications and potential disproportionate influence. However, identifying allelopathy and consequent phytotoxic effects as an important mechanism of plant invasion is a difficult task due to the potential for an individual plant to have many component chemicals with multiple modes of action, interactive effects, and synergistic interactions. For allelopathy to be implicated as a mechanism that facilitates invasion, multiple aspects of the plant species allelopathic properties must be examined. This research investigated allelopathy as a mechanism of the invasion process in Phragmites australis by a series of ecologically realistic experiments in the laboratory, greenhouse and field.
