Automated flow control of a multi-lane swimming chamber for small fishes indicates species-specific sensitivity to experimental protocols

Björn Illing, Andrea Severati, Justin Hochen, Paul Boyd, Paulin Raison, Rachel Mather, Adam T. Downie, Jodie L. Rummer, Frederieke J. Kroon & Craig Humphrey
In fishes, swimming performance is considered an important metric to measure fitness, dispersal, and migratory abilities. Swimming performance of individual larval fishes is often integrated into models to make inferences on how environmental parameters affect population-level dynamics (e.g., connectivity). However, little information exists regarding how experimental protocols affect the swimming performance of marine fish larvae. In addition, the technical setups used to measure larval fish swimming performance often lack automation and accurate control of water...

Representation and complementarity of the long-term coral monitoring on the Great Barrier Reef

Camille Mellin
Effective environmental management hinges on efficient and targeted monitoring, which in turn should adapt to increasing disturbance regimes that now characterize most ecosystems. Habitats and biodiversity of Australia’s Great Barrier Reef (GBR) - the world’s largest coral reef ecosystem - are in declining condition, prompting a review of the effectiveness of existing coral monitoring programs. Applying a regional model of coral cover (i.e., the most widely used proxy for coral reef condition globally) within major...

Data from: A closer examination of the 'abundant center' hypothesis for reef fishes

Itai Granot, Hagar Yancovitch Shalom, Shane Blowes, Alan Friedlander, Camille Mellin, Carlos Ferreira, Arias-González Ernesto, Michel Kulbicki, Sergio Floeter, Pascal Chabanet, Valeriano Parravicini & Jonathan Belmaker
Aim: The ‘abundant center’ hypothesis states that species are more abundant at the center of their range. However, several recent large-scale studies have failed to find evidence for such a pattern. Here we use extensive global data of reef fishes to test the strength of the 'abundant center' pattern, and to examine variation in the patterns across species using life history and ecological traits. Location: Marine habitat at a global extent: from Indo-Pacific to Atlantic...

Swim with the tide: tactics to maximise prey detection by a specialist predator, the greater sea snake (Hydrophis major)

Vinay Udyawer, Claire Goiran, Olivier Chateau & Richard Shine
The fitness of a predator depends upon its ability to locate and capture prey; and thus, increasing dietary specialization should favor the evolution of species-specific foraging tactics tuned to taxon-specific habitats and cues. Within marine environments, prey detectability (e.g., via visual or chemical cues) is affected by environmental conditions (e.g., water clarity and tidal flow), such that specialist predators would be expected to synchronize their foraging activity with cyclic variation in such conditions. In the...

Data from: Depth dependent dive kinematics suggest cost-efficient foraging strategies by tiger sharks

Samantha Andrzejaczek, Adrian Gleiss, Karissa Lear, Charitha Pattiaratchi, Taylor Chapple & Mark Meekan
Tiger sharks Galeocerdo cuvier are a keystone, top-order predator that are assumed to engage in cost-efficient movement and foraging patterns. To investigate the extent to which patterns of oscillatory diving by these animals conform to these patterns, we used a biologging approach to model their cost of transport. High-resolution biologging tags with tri-axial sensors were deployed on 21 tiger sharks at Ningaloo Reef for durations of 5-48 hours. Using overall dynamic body acceleration (ODBA) as...

Data from: Extreme seascape drives local recruitment and genetic divergence in brooding and spawning corals in remote northwest Australia

Jim Underwood, Zoe Richards, Oliver Berry, Daniel Oades, Azton Howard & James Gilmour
Management strategies designed to conserve coral reefs threatened by climate change need to incorporate knowledge of the spatial distribution of inter- and intra-specific genetic diversity. We characterised patterns of genetic diversity and connectivity using single nucleotide polymorphisms (SNPs) in two reef-building corals to explore the eco-evolutionary processes that sustain populations in northwest Australia. Our sampling focused on the unique reefs of the Kimberley; we collected the broadcast spawning coral Acropora aspera (n = 534) and...

Limited evidence of cloning and selfing within wild populations of coral-eating crown-of thorns seastar (Acanthaster cf. solaris)

Sven Uthicke, Morgan Pratchett, Vanessa Messmer & Hugo Harrison
Population outbreaks of crown-of-thorns seastars (CoTS; Acanthaster spp.) are contributing to extensive coral loss and reef degradation throughout the Indo west-Pacific, but the causes and underlying mechanisms of population maintenance and outbreaks are equivocal. Two recent publications suggest that, in addition to outbreeding sexual reproduction, asexual reproduction through larval fission and selfing may contribute to rapid increases in the local abundance of Acanthaster spp. We re-analysed two large microsatellite datasets (collectively representing 3,714 individuals) that...

Data from: Optimising sample sizes for animal distribution analysis using tracking data

Takahiro Shimada, Michele Thums, Mark Hamann, Colin Limpus, Graeme Hays, Nancy FitzSimmons, Natalie Wildermann, Carlos Duarte & Mark Meekan
1. Knowledge of the spatial distribution of populations is fundamental to management plans for any species. When tracking data are used to describe distributions, it is sometimes assumed that the reported locations of individuals delineate the spatial extent of areas used by the target population. 2. Here, we examine existing approaches to validate this assumption, highlight caveats, and propose a new method for a more informative assessment of the number of tracked animals (i.e. sample...
