In Australia, for eight months of each year Sydney's most popular beaches are laced with fishing nets. Stretching 150 metres (492 feet) across, and set within 500 metres (1,640 feet) of the shore, the nets are anchored off fifty-one beaches between Newcastle in the north and Wollongong in the south. The aim of the Shark Meshing (Bather Protection) Program NSW is to reduce the risk of dangerous encounters between sharks and people, and specifically to deter sharks from establishing territories (Department of Primary Industries NSW 2009, 2015). Program managers achieve such ends by devising and deploying tools and employing people to catch and kill sharks. By considering what happens when non-human animals are enlisted in territorialising practices of shore control, this chapter examin es and unsettles the interplay between multiple interpretations of territory and the political implications of those interpretations. The work traces the state of New South Wales' Shark Meshing (Bather Protection) Program to understand how ter- ritory is claimed, asserted, and confounded at the shore. Grasping the ways in which territory is made and remade at the shore is important conceptually, politically, and practically, as it sheds light on our understanding of territory. More specifically then, this work is also important because these practices have direct implications for the safety and well-being of people, and for the conservation of marine animals, species, and environments. Especially significant in this case is the question of how the Shark Meshing Program plays out for several species of shark that are at once formally recognised as threatened and as potentially threatening to humans. The shore is our point of departure: the line where the land meets the sea. The broader transitional zone - the coast - includes areas above and below the water line, a zone where terrestrial environments and processes influence marine ones, and vice versa (Woodroffe 2002).

For rocky intertidal organisms, temperature is often considered the most influential factor governing early survival and growth. Nevertheless, our review of the literature revealed that few studies have manipulated temperatures in the field to test for effects on these critical early life history processes. Here, we present the results from a novel manipulation of substratum temperature using settlement plates of different colour (black, grey and white) and infrared measurements of temperature to test hypotheses that temperature influences the early survival and growth of recent settlers of the intertidal barnacle Tesseropora rosea. Mean surface temperatures of black and grey plates were as great as 5.8°C (on average 2.2°C) and 4.8°C (on average 1.6°C) hotter than white plates across the sampling period, respectively. Cooler, white plates had significantly greater settlement and early growth than hotter, black plates, but differences in plate temperature did not significantly influence early survival or recruitment, though patterns were consistent with thermal variability. Comparisons between grey coloured natural rock and plates indicate that grey plates thermally mimic natural rock. Nevertheless, on average, more than twice as many larvae settled on plates than on natural rock, but early post-settlement survival on natural rock was double that on plates, suggesting that this artificial surface may not adequately capture the natural variability in early life history processes. Regardless, our simple and repeatable thermal manipulation represents a useful tool for experimentally investigating the effects of temperature on recruitment processes and simulating future temperature variability associated with climate change.
