1. Bottom-trawl fisheries are the most-widespread source of anthropogenic physical disturbance to seabed habitats. Development of fisheries-, conservation- and ecosystem-based management strategies requires the selection of indicators of the impact of bottom trawling on the state of benthic biota. Many indicators have been proposed, but no rigorous test of a range of candidate indicators against 9 commonly-agreed criteria (concreteness, theoretical basis, public awareness, cost, measurement, historical data, sensitivity, responsiveness, specificity) has been performed. 2. Here,...

Data from: A unified framework for quantifying land carbon sequestration

Yiqi Luo, Yuanyuan Huang, Carlos Sierra & Jianyang Xia
Land ecosystems offer an effective nature-based solution to climate change mitigation by absorbing approximately 30% of anthropically emitted carbon. This absorption is primarily based on constraints from atmospheric and oceanic measurements while quantification from direct studies of the land carbon cycle itself displays great uncertainty. The latter hinders prediction of the future fate of the land carbon sink. Here, we show a unified framework for quantifying land carbon sequestration. The framework unifies all carbon cycle...

Data from: Priorities and motivations of marine coastal restoration research

Active restoration is becoming an increasingly important conservation intervention to counteract the degradation of marine coastal ecosystems. Understanding what has motivated the scientific community to research the restoration of marine coastal ecosystems and how restoration research projects are funded is essential if we want to scale-up restoration interventions to meaningful extents.Here, we systematically review and synthesize data to understand the motivations for research on the restoration of coral reefs, seagrass, mangroves, saltmarsh, and oyster reefs....

Gross primary production responses to warming, elevated CO2 , and irrigation: quantifying the drivers of ecosystem physiology in a semiarid grassland

Elise Pendall, Edmund M. Ryan, Kiona Ogle, Drew Peltier, David G. Williams, Anthony P. Walker, Martin G. De Kauwe, Belinda E. Medlyn, William Parton, Shinichi Asao, Bertrand Guenet, Anna B. Harper, Xingjie Lu, Kristina A. Luus, Sönke Zaehle, Shijie Shu, Christian Werner & Jianyang Xia
Determining whether the terrestrial biosphere will be a source or sink of carbon (C) under a future climate of elevated CO2 (eCO2) and warming requires accurate quantification of gross primary production (GPP), the largest flux of C in the global C cycle. We evaluated 6 years (2007–2012) of flux‐derived GPP data from the Prairie Heating and CO2 Enrichment (PHACE) experiment, situated in a grassland in Wyoming, USA. The GPP data were used to calibrate a...

Data from: Niche partitioning between river shark species is driven by seasonal fluctuations in environmental salinity

Ross Dwyer, Hamish Campbell, Rebecca Cramp, Colin Burke, Mariana Micheli-Campbell, Richard Pillans, Barry Lyon & Craig Franklin
Tropical rivers and estuaries are highly dynamic environments, where environmental conditions change dramatically over spatial and temporal scales. This creates both physiological and ecological challenges for euryhaline elasmobranchs, where fluctuations in salinity can impact not only osmoregulatory function, but also the ability to find and acquire prey. We investigated how spatial and temporal variation in environmental salinity influences physiological homeostasis, habitat utilisation, and migration timing in two euryhaline carcharhinid sharks within a tropical river in...

Data from: Combined mechanistic modelling predicts changes in species distribution and increased co-occurrence of a tropical urchin herbivore and a habitat-forming temperate kelp

Louise Castro, Paulina Cetina-Heredia, Moninya Roughan, Symon Dworjanyn, Loic Thibaut, Matthew Chamberlain, Ming Feng & Adriana Vergés
This dataset aims to identify climate change impacts on spawning and settlement of a tropical herbivore, the sea-urchin, Tripneustes gratilla, along eastern Australia and into the Tasman Sea including Lord Howe Island. The dataset contains the trajectories of particles that represent T. gratilla larvae and their dispersal by ocean currents for each day of both a contemporary (2006-2015) and future ‘business as usual’ RCP 8.5 climate change scenario (2090-2100). T. gratilla larval dispersal under both...
