Embedding learning abroad as part of the curriculum has become popular in Australia, Canada, New Zealand, the US and European countries. In Australia, the government has actively promoted and committed to funding students’ learning abroad in the Indo-Pacific region which is considered to be strategic to the nation's prosperity and public diplomacy....
Article
Macrocystis pyrifera (Linnaeus) C. Agardh (Ochrophyta), also known as giant kelp, is a key species in coastal ecosystems of temperate regions worldwide providing important habitats and food for a range of species. M. pyrifera also has the potential for cultivation for commercial application (e.g. food, food additives and feed). This study compared...
Article
Global demand for seaweed is increasing alongside the interest for sustainable aquaculture, stimulating industry investment in the production of seaweeds, particularly through integrated multitrophic aquaculture systems. We report the first results of the nutritional value (proximate composition, fatty acids, and dietary minerals) and heavy metal p...
Article
Nurse plants modify the environment beneath their canopies to create favourable habitats for propagule recruitment. Nurse plants are potentially valuable tools for ecological restoration – yet empirical tests, particularly in polluted environments, remain rare. The few studies that do exist find that nurse‐plants positively affect propagule recruit...
Article
Marine science picture books have the capacity to shape what young people know and how they think about ocean environments and marine biodiversity. Despite academic scholarship on marine science literacy broadly, relatively little has been done to study the role of picture books in teaching children about this topic. This paper is an attempt to fil...
Article
One in four Australian undergraduate students participates in learning abroad during their study. Since 2012, faculty-led mobility programmes have overtaken exchange programs to become the most popular outbound mobility type in Australia. However, little has been known about how faculty-led short-term mobility programmes affect students’ employabil...
Article
Full-text available
The swimming of male gametes of brown algae is controlled by two heterokont flagella, regardless of reproductive system, but the patterns of flagellar movement can vary. We investigated sperm chemotaxis and phototaxis in four oogamous Australasian fucalean species. Sperm morphology was similar to that of male gametes of isogamous and anisogamous sp...
Article
Full-text available
Rising ocean temperatures and extreme temperature events have precipitated declines and local extinctions in many marine species globally, but patterns of loss are often uneven across species ranges for reasons that are poorly understood. Knowledge of the extent of local adaptation and gene flow may explain such patterns and help predict future tra...
Article
Seeding twines are convienient for outplanting cultured seaweeds, facilitating seeding in high densities. Twines are typically made of synthetic polymer fibres, likely for increased durability and economic benefits relative to natural fibres. However, synthetic twines can contribute to oceanic plastic pollution if fragmented or lost at sea, whereas...
Article
Complex haploid‐diploid life cycles amongst marine organisms may be maintained by ecological differences in life‐history phases. For red algal species within the Gigartinaceae, such differences may be driven, in part, by different cell wall composition and resultant biomechanical strengths of haploid and diploid phases. A field experiment tested th...
Article
Full-text available
The fucoid Phyllospora comosa has sparked interest from the industry as a potential commercial aquaculture species. However, information on the feasibility of culturing this species, including maximising spawning and fertilisation, remains limited. This study aimed to identify optimal conditions for spawning and early development of P. comosa under...
Article
Full-text available
Recognition of the wide diversity of organisms that maintain complex haploid‐diploid life cycles has generated interest in understanding the evolution and persistence of such life cycles. We empirically tested the model that complex haploid‐diploid life cycles may be maintained by subtle/cryptic differences in the vital rates of isomorphic haploid‐...

Article
Full-text available
Stable isotope analysis (SIA) can be a useful tool for tracking the long-distance movements of migratory taxa. However, local-scale sources of isotopic variation, such as differences in habitat use or foraging patterns, may complicate these efforts. Few studies have evaluated the implications of local-scale foraging specializations for broad-scale...

Full-text available
The Australasian fucoid, Hormosira banksii, commonly known as ‘Neptune’s necklace’ or ‘bubbleweed’ is regarded as an autogenic ecosystem engineer with no functional equivalents. Population declines resulting from climate change and other anthropogenic disturbances pose significant threats to intertidal biodiversity. For effective conservation strat...
Article
As coastal population growth increases globally, effective waste management practices are required to protect biodiversity. Water authorities are under increasing pressure to reduce the impact of sewage effluent discharged into the coastal environment and restore disturbed ecosystems. We review the role of benthic macroalgae as ecosystem engineers...
Poster
Seaweeds have complex life cycles but with significant variations amongst different taxonomic groups. Because of the sheer diversity of southern Australian seaweeds, the life history dynamics are poorly understood for many species of potential commercial value. There are many factors that can affect the yield and quality of seaweeds grown in aquacu...
Conference Paper
The fucoid alga Sargassum confusum C.Agardh, common to the shallow subtidal reefs of many Asian waters, provides habitat for phytal animals. Sargassum confusum occurs along the Tohoku coast of Japan, and consists of perennial basal laterals with annual upper laterals that die off in late summer and grow back in late winter. Phytal animals e.g. crus...

Full-text available
Macroalgal communities in Australia and around the world store vast quantities of carbon in their living biomass, but their prevalence of growing on hard substrata means that they have limited capacity to act as long-term carbon sinks. Unlike other coastal blue carbon habitats such as seagrasses, saltmarshes and mangroves, they do not develop their...
Article
Full-text available
Many marine ecosystems have the capacity for long-term storage of organic carbon (C) in what are termed 'blue-carbon' systems. While blue carbon systems (saltmarsh, mangrove and seagrass) are efficient at long-term sequestration of organic carbon (C), much of their sequestered C may originate from other (allochthonous) habitats. Macroalgae, due to...

Hormosira banksii is a dominant intertidal alga characterised by limited dispersal of propagules, yet it has a broad distribution throughout temperate Australasia. However, the high abundance of beach wrack of H. banksii on sandy beaches along southwest Victoria, the frequency of frond dislodgment and the force required to break it from the substra...
Article
Full-text available
Understanding of macroalgal dispersal has been hindered by the difficulty in identifying propagules. Different carrageenans typically occur in gametophytes and tetrasporophytes of the red algal family Gigartinaceae, and we may expect that carpospores and tetraspores also differ in composition of carrageenans. Using Fourier transform infrared (FT-IR...

In recent years there has been an increase in community-based monitoring programmes developed and implemented worldwide. This paper describes how the data collected from such a programme could be integrated into a Geographic Information System (GIS) to create temperate subtidal marine habitat maps. A differential Global Positioning System was utili...
Article
Our experience suggests trained community voluteers can collect reliable habitat data that can be used to ground-truth habitat maps in a cost effective- manner. Without a basic understanding of the delineation of subtidal habitats, marine ecosystems cannot be managed effectively, and importantly the effects of climate change, protection or other hu...
Article
Full-text available
Hormosira banksii is distributed throughout southern Australasia, but dispersal of propagules is thought to be limited. In the present study, the hypothesis that outbreeding depression occurs in H. banksii was tested by assessing fertilisation success and early development of embryos in crosses between populations at local to regional spatial scale...
