Bringing a Time–Depth Perspective to Collective Animal Behaviour

The field of collective animal behaviour examines how relatively simple, local interactions between individuals in groups combine to produce global-level outcomes. Existing mathematical models and empirical work have identified candidate mechanisms for numerous collective phenomena but have typically focused on one-off or short-term performance. We argue that feedback between collective performance and learning – giving the former the capacity to become an adaptive, and potentially cumulative, process – is a currently poorly explored but crucial mechanism in understanding collective systems. We synthesise material ranging from swarm intelligence in social insects through collective movements in vertebrates to collective decision making in animal and human groups, to propose avenues for future research to identify the potential for changes in these systems to accumulate over time

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Global data set of long-term summertime vertical temperature profiles in 153 lakes

Climate change and other anthropogenic stressors have led to long-term changes in the thermal structure, including surface temperatures, deepwater temperatures, and vertical thermal gradients, in many lakes around the world. Though many studies highlight warming of surface water temperatures in lakes worldwide, less is known about long-term trends in full vertical thermal structure and deepwater temperatures, which have been changing less consistently in both direction and magnitude. Here, we present a globally-expansive data set of summertime in-situ vertical temperature profiles from 153 lakes, with one time series beginning as early as 1894. We also compiled lake geographic, morphometric, and water quality variables that can influence vertical thermal structure through a variety of potential mechanisms in these lakes. These long-term time series of vertical temperature profiles and corresponding lake characteristics serve as valuable data to help understand changes and drivers of lake thermal structure in a time of rapid global and ecological change

Living through a national emergency: A view of the intervention from ground zero

This seminar provides a perspective on the Intervention from one of the largest Indigenous townships in the NT through the eyes of two doctoral research scholars who were researching in the community as the Intervention broke. The paper analyses the initial reactions of both the people of the region and their local organisations, as well as detailing their interactions with the Northern Territory Emergency Response Taskforce and other government agencies during the first month of the Intervention. In so doing, the presenters posit the local experience of the Intervention as a transformative and traumatic moment in the township\u27s relationship with state and explore a deeper question around the nature of the intervention and its bearing upon the concept of state and local engagement in the post-Intervention period

Aboriginal and Torres Strait Islander health: watching our words

In recent years, there has been increasing concern about the ways government and media discourses often portray Aboriginal and Torres Strait Islander people as “lacking” relative to the “average” Australian

Boarding off and on Country: A study of education in one Northern Territory remote community

In 2020, young people from remote communities in Australia’s Northern Territory are required to attend boarding school in order to access a full secondary education. Commissioned by elders in one Northern Territory remote community, this report investigates the intended and unintended consequences of this policy approach at individual and community level. Working with families, researchers tracked the education histories of 100 12–21-year-old young people identified as community members. Findings reveal that for this community, the supply of boarding places is not equal to demand, and that families experience difficulties securing secondary pathways for their children. Members of the research cohort had been dispersed among 38 different schools across 16 cities or towns in every state or territory of mainland Australia. A concerning pattern of early disengagement from education and low levels of academic attainment is apparent, with consequences for youth wellbeing and community cohesion. Findings of the study indicate the need for further systems-level research to test the generalisability of findings across other remote communities. They demonstrate that educational determinants in remote contexts (such as the community in this study) including housing, health, justice and employment need to be explicitly understood and quantified in policy discussions concerning educational effectiveness and secondary provision cost. The study has shown a large disconnect between local educational aspiration and system-level provision. Policy decisions should seek to identify models which are shown to increase the likelihood of education engagement and attainment in place. The community involved in this study are adamant that ‘place-based approaches’ to educational development must be paramount. This is likely to be generalised to other remote settings
