In 2019, the international year of indigenous languages, and the year after the University of the South Pacific’s 50th anniversary, we are celebrating an achievement that we had never thought possible: the introduction of degree programmes in Cook Islands Māori, Rotuman, Tongan and Niuafo‘ou, Vagahau Niue, and Vanuatu Language Studies, alongside Fijian, the only indigenous language that had had a place in our curriculum until 2018. These programmes are aimed at fluent speakers of the languages of study, and they use these languages as medium of teaching and assessment. For the first time, English is therefore being challenged as the only language through which high-level concepts can be discussed, and through which academic research can be conducted. For the first time, Pacific languages will be taught in schools by teachers who are qualified to do so, rather than by fluent speakers who have been trained to teach other subjects. For the first time, our students can gain credit for delivering oral presentations, written essays and creative pieces in their dominant language. Even for the students who do not choose to take up this option, or who do not yet have a language programme open to them, the possibility of studying a Pacific language at our university is becoming normalised. Our aim in coming together to share our story is to lay out its complexity. If we are serious about the sustainability of these programmes, we need to engage with this complexity, and we need to keep talking about why all this matters. We need our leaders and our allies to understand that the actions we take at our university will impact the way the indigenous languages and cultures of this region are valued, used and transmitted to the next generations.
On the innovation and evolution of predatory tactics
(bioRxiv, 2019-01-25) Gokhale CS; Wignall A
Predator-prey systems are ubiquitous across ecological systems. Typical ecological models focus on the dynamics of predator-prey populations. Eco-evolutionary models integrate arms race or Red-Queen like dynamics. The roles of the predator and prey species are always assumed to be static. Nevertheless, sometimes predators can bite off more than they can chew. For example, predators that encounter multiple or dangerous prey types may need to develop new predatory tactics to capture prey. We explore the dynamics of predator-prey dynamics when the prey can injure or kill the predator. This common ecological scenario places pressure on the predator to develop novel predatory tactics to both capture prey and avoid counter-attack from prey. Taking a bottom-up approach, we develop the Holling function mechanistically and then implement it in a model of innovationselection dynamics inspired by economic theory. We show how an interdisciplinary approach can be used to explain the emergence of complex predatory behaviours. Notably, our study shows why predators may hunt dangerous prey even when safe prey are available. In a broader context, we demonstrate how a multidisciplinary approach combining ecology, evolution and economics improves our understanding of a complex behavioural trait.
This isn’t the first time New Zealand has denied a citizen their passport
(The Spinoff, 2018-03-24) Belgrave D
Earlier this month the government cancelled the New Zealand passport of a woman living in Australia, citing classified security concerns. Stripping a NZ citizen of their passport might seem unprecedented – but it's happened before, writes David Belgrave.
