Bleaching of the Great Barrier Reef The Australian (GBR) is one Earth's most extraordinary natural wonders, but it vulnerable to climate change. Ainsworth et al. have tracked effects three decades increasing heat stress on coral organisms. In past, pulses elevated temperatures that presaged hot seasons stimulated acclimation organisms and resilience thermal stress. More recently, temperature hikes been severe precluded acclimation. result has bleaching death; notably extreme during 2016 in...

Abstract As systems of marine protected areas (MPAs) expand globally, there is a risk that new MPAs will be biased toward places are remote or unpromising for extractive activities, and hence follow the trend terrestrial in being ‘residual’ to commercial uses. Such locations typically provide little protection species ecosystems most exposed threatening processes. There strong political motivations establish residual reserves minimize costs conflicts with users natural resources. These...

Global seagrass habitats are threatened by multiple anthropogenic factors. Effective management of seagrasses requires information on the relative impacts threats; however, this is rarely available. Our goal was to use knowledge experts assess activities in six global bioregions. The that threaten were identified at an international workshop and followed with a web-based survey collect vulnerability information. There consensus urban/industrial runoff, urban/port infrastructure development,...

Drones or unmanned Aerial Vehicles' (UAVs) have huge potential to improve the safety and efficiency of sample collection from wild animals under logistically challenging circumstances. Here we present a method for surveying population health that uses UAVs respiratory vapour, 'whale blow', exhaled by free-swimming humpback whales (Megaptera novaeangliae), coupled this with amplification sequencing tract microbiota. We developed low-cost multirotor UAV incorporating sterile petri dish...

Marine mammal interactions with fisheries, such as bycatch and depredation, are a common occurrence across commercial small-scale fisheries. We conducted systematic review to assess the management responses marine analyzed literature between 1995 2021 measure research trends in studies on direct indirect for: (i) high low middle-income countries, (ii) fishery operations (commercial small-scale), (iii) taxonomic groups. Management were categorized using framework described previously...

Abstract Maintaining ecological processes that underpin the functioning of marine ecosystems requires planning and management resources at an appropriate spatial scale. The Great Barrier Reef World Heritage Area (GBR) is world's largest (approximately 348 000 km 2 ) second protected area. It difficult to inform scale because high cost associated with collecting data. To address this coastal 15 m below mean sea level) habitats GBR, study determined presence distribution seagrass by generating...

Abstract Terrestrial plants use an array of animals as vectors for dispersal, however little is known biotic dispersal marine angiosperms such seagrasses. Our study in the Great Barrier Reef confirms first time that dugongs ( Dugong dugon ) and green sea turtles Chelonia mydas assist seagrass dispersal. We demonstrate these mega-herbivores consume pass faecal matter viable seeds at least three species Zostera muelleri , Halodule uninervis Halophila decipiens ). One to two per g DW were found...

Nearly a billion people depend on tropical seascapes. The need to ensure sustainable use of these vital areas is recognised, as one 17 policy commitments made by world leaders, in Sustainable Development Goal (SDG) 14 ('Life below Water') the United Nations. SDG seeks secure marine sustainability 2030. In time increasing social-ecological unpredictability and risk, scientists policymakers working towards Asia-Pacific region know: (1) How are seascapes changing? (2) What can global society do...

Abstract Aim The movement of propagules among plant populations affects their ability to replenish and recover after a disturbance. Quantitative data on recovery strategies, including the effectiveness population connectivity, are often lacking at broad spatial temporal scales. We use numerical modelling predict seagrass propagule dispersal settlement provide an approach for circumstances where direct, or even indirect, measures dynamics difficult establish.

Abstract The rate of exchange, or connectivity, among populations effects their ability to recover after disturbance events. However, there is limited information on the extent which are connected how multiple disturbances affect especially in coastal and marine ecosystems.

Protected areas are the primary strategy for maintaining natural landscapes and separating biodiversity features from preventable anthropogenic threats. The Convention on Biological Diversity calls coverage of at least 17% land by protected areas, strategic prioritization important areas. Using spatially explicit reserve design software, Marxan, this study combines climate refugia modelled under future climates in year 2070 bioregions to identify priority sites area expansion change state...

Secondarily marine vertebrates are thought to live independently of fresh water. Here, we demonstrate a paradigm shift for the widely distributed pelagic sea snake, Hydrophis (Pelamis) platurus, which dehydrates at and spends significant part its life in dehydrated state corresponding seasonal drought. Snakes that captured following prolonged periods without rainfall have lower body water content, condition increased tendencies drink than do snakes high rainfall. These animals not seawater...
