Resumen
Seagrass meadows in oligotrophic environments are particularly susceptible to nutrient enrichment, yet morphological and architectural seagrass root responses in these ecosystems are poorly understood. This study aimed to investigate the response of Amphibolis antarctica, one of dominant seagrass species in Shark Bay, roots to nutrient additions along a salinity gradient in the oligotrophic ecosystem of Shark Bay, Western Australia. A fully factorial nutrient additional experiment with four treatments (Control, N, P and N+P) was conducted at each of five sites along a salinity gradient (between ~38ppt in site 1 and ~50ppt in site 5) in Shark Bay across a three-year period (2012-2015). In the laboratory, the roots morphology and architecture A. antarctica were investigated using a software (WinRhizo). Then, a two-way analysis of variance (ANOVA) was performed to investigate if there was a significant change in the morphology and architecture of the roots after the nutrient inputs and along five sites with salinity gradient. There was no significant impact of nutrient addition on the root’s morphology and architecture of A. antarctica species. However, the effect of site factor with salinity gradient was significant to all morphological aspects (total root length, root surface area and root diameter) of A. antarctica roots. These findings highlight the more ecological function of A. antarctica roots being in anchoring of the plant into the seafloor rather than to absorb nutrient from the sediment.Keywords: Nutrient addition, Oligotrophic habitats, Amphibolis antarctica, Shark Bay

Resumen
The impacts of tropical cyclones combined with a marine heatwave are reported for a seagrass community at Ningaloo Reef, Western Australia. A community of 9.5ha of Amphibolis antarctica was lost following a combination of cyclone-induced burial and a marine heatwave. No new seedlings have been observed since the loss; recruitment of seedlings may be impeded by local ocean circulation.

Resumen
The seagrass Amphibolis antarctica is an important component of coastal soft-sediment ecosystems across southern Australia. Large-scale losses of A. antarctica at several locations have been linked to anthropogenic nutrient inputs. The present study comprised a field survey to test whether the spatial patterns of plant biomass, canopy structure and epiphyte biomass in A. antarctica could be predicted based on expectations related to nutrient status across two regions within Gulf St Vincent, South Australia. Specific predictions were that: (1) plant biomass, plant density, plant height, leaf cluster frequency and leaf frequency are all lower in the east (higher nutrient) region than in the west region; and (2) epiphyte biomass and epiphyte load are higher in the east than in the west. Regional nutrient status was a poor predictor of most of the parameters measured, with the opposite trends to those predicted often occurring. Plant biomass, canopy structure and epiphyte biomass appear to be a result of several site-specific factors that are not fully understood at this time. The results of the present study have significant implications for making generalised predictions and for monitoring A. antarctica on urbanised coasts, and will also be useful for informing ecological studies on plant–epiphyte and plant–animal interactions in A. antarctica ecosystems.

Resumen
Le pluton central permet de bien cerner l'évolution et la mise en place de la série alcaline sous-saturée en silice. Ses caractères géochimiques et minéralogiques conduisent à l'expliquer par la cristallisation fractionnée d'un magma fortement alcalin. Des contraintes de fractionnement conduisent à proposer un modèle de deux chambres magmatiques superposées dont le style de mise en place est clairement lie à la différenciation et fait appel aux deux mécanismes reconnus : la subsidence souterraine passive qui guide les intrusions les moins différenciées et le mode en force qui est l'expression des magmas plus évolués et détermine la mise en place de la chambre superficielle.

Resumen
The Precambrian basement of the Schirmacher Hills records multiple episodes of deformation, metamorphism, migmatization, and emplacement of successive generations of mafic and felsic bodies. The earliest tectono-thermal event (D1/M1), preserved in some mafic and ultramafic enclaves, indicates deformation at great crustal depth. The mineralogical assemblage of these enclaves indicates early high temperature (900o C) and high-pressure (10 Kbar) granulite facies conditions. The second tectono-thermal event also showed deformation under granulite facies metamorphism (D2/M2) under 800-850oC and 8 Kbar. The third group of events (D3/M3) is the most dominant in this region and involved deformation under amphibolite facies conditions with synchronous emplacement of granites and mafic dykes and culminated in regional thrusting, producing a regional inversion where the granulates were emplaced over the amphibolite facies rocks. The later events created upright folds and vertical shear zones under amphibolite facies conditions.

Resumen
The studies of multifaceted problems of gneiss-charnockite rocks in the Schirmacher region of East Antarctica suggest a retrograde clockwise isobaric cooling P-T history of the terrain involving an early granulite phase, a late granulite phase, and a retrograde amphibolite phase metamorphism in the region. Also, a good correlation between fluid and mineral data is observed. The high-density CO2 fluids fall well within the P-T box estimated by mineral thermobarometers, envisaging a pervasive influx of deep-seated CO2 rich fluid from the mantle resulting in the formation of the granulites, followed by decrease CO2 density fluids along with progressive influx of hydrous fluids leading to the generation of retrograde amphibolite facies rocks. The geochemical studies helped trace two-phase evolution of the region (basic magmatism around ~1200 Ma) involving a depleted mantle source implying an accretion of the juvenile crust during the late Mesoproterozoic period and major felsic magmatism around ~880 Ma involving partial melting of mafic-intermediate crust.
