Marine Cryptophytes Are Great Sources of EPA and DHA
2017
Microalgae have the ability to synthetize many compounds, some of which have been recognized as a source of functional ingredients for nutraceuticals with positive health effects. One well-known example is the long-chain polyunsaturated fatty acids (PUFAs), which are essential for human nutrition. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the two most important long-chain omega-3 (-3) PUFAs involved in human physiology, and both industries are almost exclusively based on microalgae. In addition, algae produce phytosterols that reduce serum cholesterol. Here we determined the growth rates, biomass yields, PUFA and sterol content, and daily gain of eight strains of marine…
Fire and Plant Diversification in Mediterranean-Climate Regions
2018
Despite decades of broad interest in global patterns of biodiversity, little attention has been given to understanding the remarkable levels of plant diversity present in the world’s five Mediterranean-type climate (MTC) regions, all of which are considered to be biodiversity hotspots. Comprising the Mediterranean Basin, California, central Chile, the Cape Region of South Africa, and southwestern Australia, these regions share the unusual climatic regime of mild wet winters and warm dry summers. Despite their small extent, covering only about 2.2% of world land area, these regions are home to approximately one-sixth of the world vascular plant flora. The onset of MTCs in the middle Miocene …
A study protocol for applying the co-creating knowledge translation framework to a population health study
2013
Background: Population health research can generate significant outcomes for communities, while Knowledge Translation (KT) aims to expressly maximize the outcomes of knowledge producing activity. Yet the two approaches are seldom explicitly combined as part of the research process. A population health study in Port Lincoln, South Australia offered the opportunity to develop and apply the co-KT Framework to the entire research process. This is a new framework to facilitate knowledge formation collaboratively between researchers and communities throughout a research to intervention implementation process. Design: This study employs a five step framework (the co-KT Framework) that is formulate…
Sulfur isotope's signal of nanopyrites enclosed in 2.7 Ga stromatolitic organic remains reveal microbial sulfate reduction.
2018
18 pages; International audience; Microbial sulfate reduction (MSR) is thought to have operated very early on Earth and is often invoked to explain the occurrence of sedimentary sulfides in the rock record. Sedimentary sulfides can also form from sulfides produced abiotically during late diagenesis or metamorphism. As both biotic and abiotic processes contribute to the bulk of sedimentary sulfides, tracing back the original microbial signature from the earliest Earth record is challenging. We present in situ sulfur isotope data from nanopyrites occurring in carbonaceous remains lining the domical shape of stromatolite knobs of the 2.7-Gyr-old Tumbiana Formation (Western Australia). The anal…
NOW and WHEN Australian Urbanism. Una nuova prospettiva sulle città australiane
2011
Una nuova prospettiva sulle città australiane nell’esposizione NOW and WHEN Australian Urbanism alla Biennale di Venezia del 2010. La mostra è stata strutturata in due sezioni. Nella prima sono state messe in risalto le più interessanti regioni urbane e non urbane dell’Australia cosi come esse appaiono “ora” (NOW) ritratte da John Gollings. Nella seconda sala, 17 ambienti urbani del futuro hanno proposto immagini di “quando” (WHEN), avremo raggiunto e superato il 2050. In NOW sono stati presentati gli attuali scenari urbani di Sidney, Melbourne e Surfes Paradise e due scenari non urbani dell’entroterra australiano, zone in cui sono presenti grandi buchi prodotti dall’industria mineraria; qu…
Relationship between recruitment and mother plant vitality in the alien species Acacia cyclops A. Cunn. ex G. Don
2014
Acacia cyclops is a widespread invader in Mediterranean-climate regions. However, although its naturalization in the Mediterranean Basin dates back only a few years ago, and the invasion process has not been studied hitherto. We investigated seedlings recruitment strategy adopted by A. cyclops in a small island (Lampedusa, Italy) where its natural regeneration was strictly confined under mother plants canopy. Healthy plants (DCP), plants at incipient senescence (SCP) and dead plants (DP) were distinguished according to vitality and canopy status. Living plants were also characterized in relation to leaf C and N isotope composition. Regeneration pattern (seedlings and saplings abundance) was…
The Eighth Island
2014
This paper proposes a succinct analysis of the factors that have led Aeolians to leave their islands for Australia and explores how patterns of chain migration were established in the second half of the 19th century that are still active today. Saija argues that initially Aeolians went to Australia out of a yearning for adventure rather than out of economic need, although after the substantial economic downturn experienced by the islands from 1888 onwards, economic need became the predominant if not the only factor. Over the last 150 years so many Aeolians have migrated to Australia that it has become known in the Aeolian collective consciousness as the eighth island of the Aeolian archipel…
Quantifying submarine groundwater discharge in the coastal zone via multiple methods
2006
Submarine groundwater discharge (SGD) is now recognized as an important pathway between land and sea. As such, this flow may contribute to the biogeochemical and other marine budgets of near-shore waters. These discharges typically display significant spatial and temporal variability making assessments difficult. Groundwater seepage is patchy, diffuse, temporally variable, and may involve multiple aquifers. Thus, the measurement of its magnitude and associated chemical fluxes is a challenging enterprise. A joint project of UNESCO and the International Atomic Energy Agency (IAEA) has examined several methods of SGD assessment and carried out a series of five intercomparison experiments in di…
Glen Philips: Western Australia's poet of the land and environment
2020
Artykuł ten nawiązuje do problematyki stosunkowo młodej gałęzi, jaka rozwinęła się w krytyce literackiej ostatnich dekad, tzw. ekokrytyki i jej obecności w literaturze australijskiej na przykładzie zachodnioaustralijskiego poety i krytyka Glena Philipsa (1936–), którego poezja jest ściśle związana ze środowiskiem naturalnym, w którym wzrastał i które zawsze inspirowało jego pisarstwo. Po skrótowym przedstawieniu historii ekokrytyki w USA, Europie i Australii autor, posługując się koncepcją pochodzenia dzieła sztuki niemieckiego filozofa Martina Heideggera, interpretuje wiersz Glena Philipsa pt. „In the Hollow of the Land”, widząc w nim egzemplifikację wspólnego rozumienia świata, jaki jest …
Strategic adjustments in sperm production within and between two island populations of house mice
2012
Sperm production is physiologically costly. Consequently, males are expected to be prudent in their sperm production, and tailor their expenditure according to prevailing social conditions. Differences in sperm production have been found across island populations of house mice that differ in the level of selection from sperm competition. Here, we determined the extent to which these differences represent phenotypic plasticity and/or population divergence in sperm production. We sourced individuals from two populations at the extreme levels of sperm competition, and raised them under common-garden conditions while manipulating the social experience of developing males. Males from the high-sp…
