Abstract It is fundamentally important for many animal ecologists to quantify the costs of activities, although it not straightforward do so. The recording triaxial acceleration by animal‐attached devices has been proposed as a way forward this, with specific suggestion that dynamic body (DBA) be used proxy movement‐based power. Dynamic now validated frequently, both in laboratory and field, literature still shows some aspects DBA theory practice are misunderstood. Here, we examine behind...
Abstract Calcium carbonates (CaCO 3 ) often accumulate in mangrove and seagrass sediments. As CaCO production emits CO 2 , there is concern that this may partially offset the role of Blue Carbon ecosystems as sinks through burial organic carbon (C org ). A global collection data on inorganic rates inorg 12% mass) revealed 0.8 TgC yr −1 15–62 ecosystems, respectively. In seagrass, correspond to an 30% net sequestration. However, a mass balance assessment highlights C mainly supported by...
Abstract The outstanding properties of graphene have initiated myriads research and development; yet, its economic impact is hampered by the difficulties encountered in production practical application. Recently discovered laser-induced generated a simple printing process on flexible lightweight polyimide films. Exploiting electrical features mechanical pliability LIG polyimide, we developed wearable resistive bending sensors that pave way for many cost-effective measurement systems....
Blue carbon is the organic in oceanic and coastal ecosystems that captured on centennial to millennial timescales. Maintaining increasing blue an integral component of strategies mitigate global warming. Marine vegetated (especially seagrass meadows, mangrove forests, tidal marshes) are hotspots their degradation loss worldwide have reduced stocks increased CO2 emissions. Carbon markets, conservation restoration schemes aimed at enhancing sequestration avoiding greenhouse gas emissions, will...
Prey naiveté—the failure of prey to recognize novel predators as threats—is thought exacerbate the impact that exotic exert on populations. naiveté varies under influence eco-evolutionary mediating factors, such biogeographic isolation and adaptation, although an overall quantification their is lacking. We conducted a global meta-analysis test effects several hypothesized factors expression naiveté. were naive towards in marine freshwater systems but not terrestrial systems. was most...

Abstract Current marine research primarily depends on weighty and invasive sensory equipment telemetric network to understand the environment, including diverse fauna it contains, as a function of animal behavior size, well longevity. To match morphology activity within surrounding here we show physically flexible stretchable skin-like waterproof autonomous multifunctional system, integrating Bluetooth, memory chip, high performance physical sensors.

Advances in marine research to understand environmental change and its effect on ecosystems rely gathering data species physiology, their habitat, mobility patterns using heavy invasive biologgers sensory telemetric networks. In the past, a lightweight (6 g) compliant monitoring system: Marine Skin was demonstrated. this paper, an enhanced version of that skin with improved functionalities (500-1500% sensitivity), packaging, most importantly endurance at depth 2 km highly saline Red Sea...
Abstract While the outstanding properties of graphene have attracted a lot attention, one major bottlenecks its widespread usage is availability in large volumes. Laser printing on polyimide films an efficient single‐step fabrication process that can remedy this issue. A laser‐printed, flexible pressure sensor developed utilizing piezoresistive effect 3D porous graphene. The sensors performance be easily adjusted via geometrical parameters. They sensitivity range 1.23 × 10 −3 kPa and feature...
Abstract Over this century, coral reefs will run the gauntlet of climate change, as marine heatwaves (MHWs) become more intense and frequent, ocean acidification (OA) progresses. However, we still lack a quantitative assessment how, to what degree, OA moderate responses corals MHWs they intensify throughout century. Here, first projected future MHW intensities for tropical regions under three greenhouse gas emissions scenario (representative concentration pathways, RCP2.6, RCP4.5 RCP8.5)...
Our ability to assess biodiversity at relevant spatial and temporal scales for informing management is of increasing importance given this foundational identify mitigate the impacts global change. Collecting baseline information tracking ecological changes are particularly important areas experiencing rapid representing data gaps such as Arctic marine ecosystems. Environmental DNA has potential provide data. We extracted environmental from 90 surface sediment samples eukaryote diversity...

Abstract Estimation of marine macrophyte contribution to coastal sediments is key understand carbon sequestration dynamics. Nevertheless, identification challenging. We propose environmental DNA (eDNA) metabarcoding as a new approach for sediment contributors, and compared this against stable isotopes—the traditional approach. eDNA allowed high‐resolution 48 macroalgae, seagrasses, mangroves from habitats. The relative contributions macrophytes were similar their organic based on isotopes;...

Studies focusing on marine macrophyte metabarcoding from environmental samples are scarce, due to the lack of a universal barcode for these taxa, and their poor representation in DNA databases. Here, we searched short able identify macrophytes tissue samples; then, created reference library which was used eDNA coastal sediments. Barcoding seagrasses, mangroves macroalgae (Chlorophyta, Rhodophyta Phaeophyceae) tested using 18 primer pairs six barcoding genes: plant barcodes rbcL, matK trnL,...
