Building climate-smart fisheries in Australia: insights from climate and ecosystem status reportsNARA Subscribed
Ongoing concerns about the impact of climate change on Australia’s oceans has driven a request from fisheries managers for improved science communication to the seafood sector. Despite these concerns, translating climate science into management and industry action at regional and sectoral scales remains a challenge. We developed a reporting structure for communicating climate and ecosystem status to fisheries management, indus...
An exceptionally large blood O 2 store underlies the remarkable dive performance of elephant seals. However, elevated carboxyhemoglobin (COHb) concentrations in these seals complicate estimations of blood O 2 content and O 2 depletion rates, and may also affect monitoring of brain oxygenation in seals with new non-invasive near-infrared (NIR) recorders. Using hemoximetry analyses of blood samples during sleep apneas of juvenil...
The production of medium‐chain carboxylates (MCC) by mixed culture fermentation of complex organic feedstocks is often constrained by the availability of reducing equivalents. Therefore, mixotrophic fermentation processes, which integrate diverse carbon and reducing equivalents sources, are gaining more attention. However, the microbial communities evolving in such complex environments, where organic and inorganic substrates i...
Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers. One such technique is passive acoustic monitoring, which is commonly coupled with automatic identification of animal sp...
Run-of-river power plants (ROR) represent the majority of hydroelectric plants worldwide. Their environmental impacts are not well documented and are believed to be limited, particularly regarding the contamination of food webs by methylmercury (MeHg), a neurotoxin. RORs are typically installed in small rivers where combined effects of watershed disturbances with dam construction can complicate environmental management. We rep...
Effects of point‐source discharges on shortfin eels ( Anguilla australis ) along the Waikato River, New ZealandNARA Subscribed
The Waikato River is the longest river in New Zealand and is exposed to range of anthropogenic stressors. This study investigated the effects of three major point‐source discharges on resident shortfin eels Anguilla australis along the river. Shortfin eels were caught from sites upstream and downstream of discharges of bleached kraft mill effluent (BKME) from pulp and paper manufacture, sewage, and a thermal power plant. At ea...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
Anthropogenic stressors are omnipresent in marine environments and interfere with organisms of all sizes, from large whales to small organisms. We investigated potential interactive multistressor effects of increased temperature with chronic low‐frequency sound on the development and movement patterns of the calanoid copepod Acartia tonsa , a model species for small marine zooplankton. Copepods were reared while exposed to chr...
