Monitoring of intertidal reefs is traditionally undertaken by on-ground survey methods which have assisted in understanding these complex habitats; however, often only a small spatial footprint the reef observed. Recent developments unmanned aerial vehicles (UAVs) provide new opportunities for monitoring broad scale coastal ecosystems through ability to capture centimetre resolution imagery and topographic data not possible with conventional approaches. This study compares UAV remote sensing...
Abstract Overgrazing may lead to management intervention (e.g. culling, animal relocation) try and prevent habitat destruction. leading seagrass meadow collapse has been recorded for green turtles ( Chelonia mydas ) at several sites around the world, although generality of this phenomenon need widespread destruction is unknown. Where have degraded meadows, home‐ranges are expected be large will relocate as meadows destroyed. We used high resolution Fastloc GPS tracking n = 32 individuals,...

Here, we evaluated the potential of using bathymetric Light Detection and Ranging (LiDAR) to characterise shallow water (<30 m) benthic habitats high energy subtidal coastal environments. Habitat classification, quantifying substrata macroalgal communities, was achieved in this study with application LiDAR underwater video groundtruth data automated classification techniques. Bathymetry reflectance datasets were used produce secondary terrain derivative surfaces (e.g., rugosity, aspect)...
Developing quantitative and objective approaches to integrate multibeam echosounder (MBES) data with ground observations for predictive modelling is essential ensuring repeatability providing confidence measures benthic habitat mapping. The scale of predictors within models directly influences distribution maps, therefore matching the environmental drivers key improving model accuracy. This study uses a multi-scalar hierarchical classification approach improve accuracy maps. We used 700-km2...
The new found ability to measure physical attributes of the marine environment at high resolution across broad spatial scales has driven rapid evolution benthic habitat mapping as a field in its own right. Improvement and ecological validity seafloor distribution models has, for most part, paralleled developments generations acoustic survey tools such multibeam echosounders. While sonar methods have been well demonstrated provide useful proxies relatively static geophysical patterns that...
Abstract Characterising adaptive genetic divergence among conspecific populations is often achieved by studying variation across defined environmental gradients. In marine systems this challenging due to a paucity of information on habitat heterogeneity at local and regional scales dependency sampling regimes that are typically limited broad longitudinal latitudinal As result, the spatial which selection processes operate factors contribute adaptation in likely be unclear. study we explore...

Planning for resilience is the focus of many marine conservation programs and initiatives. These efforts aim to inform strategies regions ensure they have inbuilt capacity retain biological diversity ecological function in face global environmental change--particularly changes climate resource exploitation. In absence direct information species, scientists are increasingly using spatially-explicit, predictive-modeling approaches. Through improved access multibeam sonar underwater video...
Assessing patterns of fisheries activity at a scale related to resource exploitation has received particular attention in recent times. However, acquiring data about the distribution and spatiotemporal allocation catch fishing effort small benthic remains challenging. Here, we used GIS-based spatio-statistical models investigate footprint commercial diving events on blacklip abalone (Haliotis rubra) stocks along south-west coast Victoria, Australia from 2008 2011.

This study presents an analysis of the application underwater video data collected for training and validating benthic habitat distribution models. Specifically, we quantify two major sources error pertaining to collection this type reference data. A theoretical spatial budget is developed a positioning system used co-register frames their corresponding locations at seafloor. Second, compare interpretation variability among trained operators assessing same between times over three...
Space use estimates can inform conservation management but relaying high-accuracy locations is often not straightforward. We used Fastloc-GPS Argos satellite tags with the innovation of additional data relay via a ground station (termed "Mote") to record high volumes (typically >20 per individual day) accuracy tracking data. Tags were attached in Chagos Archipelago (Indian Ocean) 2018-2019 23 immature turtles two species for which there have been long-standing concerns: 21 hawksbill...
Biological invasions are acknowledged among the main drivers of global changes in biodiversity. Despite compelling evidence species interactions being strongly regulated by environmental conditions, there is a dearth studies investigating how effects non‐native vary areas exposed to different anthropogenic pressures. Focusing on marine macroalgae, we performed meta‐analysis test whether and direction magnitude their resident communities varies relation cumulative impact levels. The...
The difficulty in teasing apart the effects of biological invasions from those other anthropogenic perturbations has hampered our understanding mechanisms underpinning global biodiversity crisis. recent elaboration global-scale maps cumulative human impacts provides a unique opportunity to assess how impact invaders varies among areas exposed different activities. A meta-analysis shown that invasive seaweeds on native biota tend be more negative relatively pristine than human-impacted...
How animals navigate across the ocean to isolated targets remains perplexing greater than 150 years since this question was considered by Charles Darwin. To help solve long-standing enigma, we likely resolution of any map sense used in migration, based on navigational performance different scales (tens thousands kilometres). We assessed using a unique high-resolution Fastloc-GPS tracking dataset for post-breeding hawksbill turtles ( Eretmochelys imbricata ) migrating relatively short...
The importance of some ecosystems remains poorly understood. We showed that mesophotic (30 to 150 m) are a key habitat for critically endangered species, with strong evidence globally important population adult hawksbill turtles (
Abstract Satellite tracking of animals is very widespread across a range marine, freshwater, and terrestrial taxa. Despite the high cost tags advantages long deployments, reasons why data from stop being received are rarely considered, but possibilities include shedding tag, damage to tag (e.g., aerial), biofouling, battery exhaustion, or animal mortality. We show how information relayed via satellite can be used assess received. As case study illustrate general approaches that broadly...
