The recent introduction of low-cost, moored data-logging acoustic receivers has provided opportunities for tracking marine organisms over small (hundreds metres) and large scales kilometres). Acoustic have been deployed in many different environments to examine specific hypotheses regarding the movement aquatic species. This technology provides advantages studying animal patterns, but also limitations unique difficulties users. Study design, applications, are discussed with examples from...
Significance We conducted a systematic, high-resolution analysis of bottom trawl fishing footprints for 24 regions on continental shelves and slopes five continents New Zealand. The proportion seabed trawled varied >200-fold among (from 0.4 to 80.7% area depth 1,000 m). Within 18 regions, more than two-thirds remained untrawled during study periods 2–6 years. Relationships between metrics total trawling activity footprint were strong positive, providing method estimate where data are not...
Within the set of risk factors that compromise conservation marine biodiversity, one least understood concerns is noise produced by human operations at sea and from land. Many aspects how other forms energy may impact natural balance oceans are still unstudied. Substantial attention has been devoted in last decades to determine sensitivity mammals—especially cetaceans pinnipeds—and fish because they known possess hearing organs. Recent studies have revealed a wide diversity invertebrates...

Summary Acoustic telemetry is being increasingly used to study the ecology of many aquatic organisms. This widespread use has been advanced by national and international tracking programs that coordinate deployment passive acoustic networks on a regional continental scale detect tagged animals. While it well‐known environmental conditions can affect performance receivers, these effects are rarely quantified despite profound implications for tag detection hence ecological inferences. Here, we...
Abstract Understanding how aquatic species respond to extremes of DO and temperature is crucial for determining they will be affected by climate change, which predicted increasingly expose them levels beyond their optima. In this study we used novel animal-borne DO, depth sensors determine the effect on vertical habitat use Atlantic salmon Salmo salar in aquaculture cages. Salmon showed a preference temperatures around 16.5 17.5 °C, however, selection preferred was trumped active avoidance...
Environmental DNA (eDNA) techniques have only recently been applied in the marine environment to detect presence of species. Species-specific primers and probes were designed eDNA endangered Maugean skate (Zearaja maugeana) from as little 1 L water collected at depth (10-15 m) Macquarie Harbour (MH), Tasmania. The identity was confirmed Z. maugeana by sequencing qPCR products aligning these with target sequence for a 100% match. This result has validated use this technique detecting rare...
In the age of Anthropocene, ocean has typically been viewed as a sink for pollution. Pollution is varied, ranging from human-made plastics and pharmaceutical compounds, to human-altered abiotic factors, such sediment nutrient runoff. As global population, wealth resource consumption continue grow, so too does amount potential pollution produced. This presents us with grand challenge which requires interdisciplinary knowledge solve. There sufficient data on human health, social, economic,...
Marine ecosystems and their associated biodiversity sustain life on Earth hold intrinsic value. Critical marine ecosystem services include maintenance of global oxygen carbon cycles, production food energy, sustenance human wellbeing. However are swiftly being degraded due to the unsustainable use environments a rapidly changing climate. The fundamental challenge for future is therefore safeguard biodiversity, function, adaptive capacity whilst continuing provide vital resources population....
Octopuses are generally characterised by rapid non-asymptotic growth, with high individual variability. However, in situ octopus growth is not well understood. The lack of an ageing method has resulted the majority our understanding coming from laboratory studies. Despite being applicable to cephalopods, Modal Progression Analysis (MPA) length–frequency data most common for examining growth. Recently, counting increments beaks and vestigial shells, quantifying lipofuscin brain tissue, have...
Many salmon populations in both the Pacific and Atlantic Oceans have experienced sharply decreasing returns high ocean mortality past two decades, with some facing extirpation if current marine survival trends continue. Our inability to monitor movements of fish or directly measure their precludes experimental tests theories concerning factors regulating populations, thus limits scientific advance many aspects fisheries management conservation. Here we report a large-scale synthesis movement...
1. Estimating the metabolic rate of animals in nature is central to understanding physiological, behavioural and evolutionary ecology animals. Doubly labelled water heart-rate methods are most commonly used approaches, but both have limitations that preclude their application some systems. 2. Accelerometry has emerged as a powerful tool for estimating energy expenditure range animals, yet be estimate field aquatic taxa. We combined two-dimensional accelerometry swim-tunnel respirometry...
ABSTRACT Some fishes and sea turtles are distinct from ectotherms by having elevated core body temperatures metabolic rates. Quantifying the energetics activity of regionally endothermic species will help us understand how a fundamental biophysical process (i.e. temperature-dependent metabolism) shapes animal ecology; however, such information is limited owing to difficulties in studying these large, highly active animals. White sharks, Carcharodon carcharias, largest fish with regional...
Activity rhythms are ubiquitous in nature, and generally synchronized with the day–night cycle. Several taxa have been shown to switch between nocturnal diurnal activity response environmental variability, these relatively uncommon switches provide a basis for greater understanding of mechanisms adaptive significance circadian (approx. 24 h) rhythms. Plasticity has identified association variety factors, from changes predation pressure an altered nutritional or social status. Here, we report...
