Abstract: This study of the relationships between the Antarctic, sub-Antarctic and South America biogeographical regions used both existing and new data. We constructed a presence/absence matrix of 237 species for 27 biogeographical isions which included the Amsterdam-Saint Paul and Tristan da Cunha islands. Species and areas were classified using cluster analysis combined with MDS ordination. Six main groups were obtained from the species classification: 1) Amsterdam-Saint Paul, and 2) Tristan da Cunha species, 3) species from the Macquarie Province, 4) species from the sub-Antarctic Region, 5) Antarctic species and species distributed in the cold regions, 6) South American species. The biogeographical components were dominated by the endemic (although it is not as high as in other groups), Antarctic-South America and Southern Hemisphere elements. Except for Amsterdam-Saint Paul, Tristan da Cunha and Bouvet, the areas considered were grouped together with Macquarie being rather related to New Zealand regions. We speculate that the Antarctic Region may have acted as an “evolutionary incubator”, providing a centre of origin for sub-Antarctic and South American ascidians.

Abstract: Assessments of the severity of food insecurity within Australian university students are lacking, and the experience of food insecurity in Australian university staff is unknown. A cross-sectional online survey in March 2022 aimed to characterize the severity of food insecurity in students, professional and academic staff at the University of Tasmania (UTAS). The Household Food Security Survey Module six-item short form assessed food security status in addition to seven demographic and education characteristics for students and six demographic and employment characteristics for staff. Participants were categorized as having high, marginal, low, or very low food security. Multivariate binary logistic regression identified students and staff at higher risk of food insecurity. Among student respondents (n = 1257), the prevalence of food insecurity was 41.9% comprising 8.2% marginal, 16.5% low, and 17.3% very low food security. Younger, non-binary, first-year enrolled, on c us, and international students were at significantly higher risk of food insecurity. Among staff (n = 560), 16.3% were food insecure comprising 3.8% marginal, 5.5% low, and 7.0% very low food security. Professional staff, staff on casual contracts, and staff recently employed, were at significantly higher risk of food insecurity. Our findings suggest a high occurrence of food insecurity in UTAS students and staff, with a large proportion of food insecure staff and students experiencing very low food security. Our findings have implications for efforts towards reducing food insecurity at university c uses through a holistic and integrated approach, advocating for food systems that support healthy, sustainable, and equitable food procurement and provision for both university students and staff.

Abstract: We evaluated two risk models (bioregion pathway and species-based exposure), with the aim to determine an effective strategy to implement marine biosecurity risk management in regions/countries where biological data are limited. We used the Port of Tanjung Priok, Jakarta Bay, Indonesia, as a case study to test both models. The bioregion pathway model illustrates that Tanjung Priok is highly connected to the East Asian Sea (∼91%), and the Northwest Pacific, Mediterranean, and Australia & New Zealand bioregions (“Very Low” risk), with other bioregions posing “Negligible” risk, highlighting the importance of understanding regional port linkages. The bioregion pathway model strength is grounded by using readily available shipping data however, it does not classify species into threat categories but considers a larger number of species as an increasing threat. The species exposure model found that 51 species pose a theoretical risk (10 “Moderate”, 20 “High”, and 21 “Extreme” risks) to Tanjung Priok. These 51 species can be used as a “watch list” for this port. If biosecurity measures for this port were restricted to the outcomes of the bioregion pathway model only 4 of the 51 species highlighted by the species exposure model would have been captured. The species model was data intensive, requiring extensive species datasets and consequently may be unsuitable when data are limited.

Abstract: Reduced competition is a frequent explanation for the success of many introduced species. In benthic marine biofouling communities, space limitation leads to high rates of overgrowth competition. Some species can utilise other living organisms as substrate (epibiosis), proffering a competitive advantage for the epibiont. Additionally, some species can prevent or reduce epibiotic settlement on their surfaces and avoid being basibionts. To test whether epibiotic pressure differs between native and introduced species, we undertook ex situ experiments comparing bryozoan larval settlement to determine if introduced species demonstrate a greater propensity to settle as epibionts, and a reduced propensity to be basibionts, than native species. Here we report that introduced species opportunistically settle on any space (bare, native, or introduced), whereas native species exhibit a strong tendency to settle on and near other natives, but avoid settling on or near introduced basibionts. In addition, larvae of native species experience greater larval wastage (mortality) than introduced species, both in the presence and absence of living substrates. Introduced species’ ability to settle on natives as epibionts, and in turn avoid epibiosis as basibionts, combined with significantly enhanced native larval wastage, provides a comprehensive suite of competitive advantages contributing to the invasion success of these biofouling species.

Abstract: Food insecurity and poor access to healthy food is known to compromise tertiary studies in university students, and food choices are linked to student perceptions of the c us food environment. The purpose of this study is to describe the prevalence, demographic and education characteristics associated with food insecurity in a s le of Australian university students and their satisfaction with on-c us food choices. An online, cross-sectional survey conducted as part of the bi-annual sustainability themed survey was conducted at the University of Tasmania in March 2020. A single-item measure was used to assess food insecurity in addition to six demographic and education characteristics and four questions about the availability of food, affordable food, sustainable food and local food on c us. Survey data ( n = 1,858) were analysed using bivariate analyses and multivariate binary logistic regression. A total of 38% of respondents (70% female 80% domestic student 42% aged 18–24 years) were food insecure. Overall, 41% of students were satisfied with the food available on c us. Nearly, half (47%) of food insecure students were dissatisfied or very dissatisfied with the availability of affordable food on c us. A minority of students were satisfied with the availability of sustainable food (37%) and local food (33%) on c us. These findings demonstrate a high prevalence of food insecurity and deficits in the university food environment, which can inform the development of strategies to improve the food available on c us, including affordable, sustainable and local options.

Abstract: Although there has been considerable research on consumers’ opinions about sustainable foods and purchasing behaviors, the experience of university students remains unclear. This study aims to characterize university students’ perceptions of the importance of sustainable foods and determine the relationship between perceptions and the frequency of purchasing sustainable foods. In a non-random s le of university students, a cross-sectional, online survey determined students’ perceptions of the importance of locally grown food and sustainable foods, and the self-reported frequency of purchasing sustainable foods. Multivariate binary logistic regression was conducted. Survey respondents (n = 1858 71% female 80% domestic enrolled 43% aged 18–24 y 38% food insecure) perceived locally grown food (77%) and sustainable food (84%) as important, and 68% reported buying sustainable foods frequently. Students who purchased sustainable foods frequently were more likely to be female, older and food insecure, and also were significantly more likely to perceive sustainable foods as important (OR: 7.317 95%-CI: 5.538–9.667 SE: 0.142 p 0.001). Our results demonstrate that university students perceive sustainable foods as important and a relationship between perceptions and actions for purchasing sustainable foods is evident. Our results should inform the development of strategies within universities aligned with the United Nations Sustainable Development Goals, including improving access to locally grown and sustainable foods on c us to reflect student preferences, particularly for food insecure students.
