Data from: Invasion-mediated effects on marine trophic interactions in a changing climate: positive feedbacks favour kelp persistenceRicardo Miranda, Melinda Coleman, Alejandro Tagliafico, Maria Rangel, Lea Mamo, Francisco Barros & Brendan Kelaher
The interactive effects of ocean warming and invasive species are complex and remain a source of uncertainty for projecting future ecological change. Climate-mediated change to trophic interactions can have pervasive ecological consequences, but the role of invasion in mediating trophic effects is largely unstudied. Using manipulative experiments in replicated outdoor mesocosms, we reveal how near-future ocean warming and macrophyte invasion scenarios interactively impact gastropod grazing intensity and preference for consumption of foundation macroalgae (Ecklonia radiata...
Kelps (order Laminariales) are foundation species in temperate and arctic seas globally, but they are in decline in many places. Laminarian kelp have an alternation of generations and this poses challenges for experimental studies due to the difficulties in achieving zoospore release and gametophyte growth. Here we review and synthesize the protocols that have been used to induce zoospore release in kelps to identify commonalities and provide guidance on best practices. We found 171 papers,...
Aim The mutualistic relationship between anemones and anemonefishes is one of the most iconic examples of symbiosis. However, while anemonefishes have been extensively studied in terms of genetic connectivity, such information is lacking entirely for host sea anemones. Here, we provide the first information on the broad-scale population structure and phylogeographic patterns of three species of host sea anemone, Heteractis magnifica, Stichodactyla mertensii, and Entacmaea quadricolor. We evaluate if there is concordance in genetic structure...
Coral reefs are facing intensifying stressors, largely due to global increases in seawater temperature and decreases in pH. However, there is extensive environmental variability within coral reef ecosystems which can impact how organisms respond to global trends. We deployed spatial arrays of autonomous sensors across distinct shallow coral reef habitats to determine patterns of spatiotemporal variability in seawater physicochemical parameters. Temperature and pH were positively correlated over the course of a day due to solar...
Data from: Future climate change is predicted to affect the microbiome and condition of habitat-forming kelpZhiguang Qiu, Melinda A Coleman, Euan Provost, Alexandra H Campbell, Brendan P Kelaher, Steven J Dalton, Torsten Thomas, Peter D Steinberg & Ezequiel M Marzinelli
Climate change is driving global declines of marine habitat-forming species through physiological effects and through changes to ecological interactions, with projected trajectories for oceanwarming and acidification likely to exacerbate such impacts in coming decades. Interactions between habitat-formers and their microbiomes are fundamental for host functioning and resilience, but how such relationships will change in future conditions is largely unknown. We investigated independent and interactive effects of warming and acidification on a large brown seaweed, the...
Data from: Fighting and mating success in giant Australian cuttlefish is influenced by behavioural lateralizationAlexandra K. Schnell, Christelle Jozet-Alves, Karina C. Hall, Léa Radday & Roger T. Hanlon
Behavioural lateralization is widespread. Yet, a fundamental question remains, how can lateralization be evolutionary stable when individuals lateralized in one direction often significantly outnumber individuals lateralized in the opposite direction? A recently developed game theory model predicts that fitness consequences that occur during intraspecific interactions may be driving population-level lateralization as an evolutionary stable strategy. This model predicts that (i) minority-type individuals exist because they are more likely to adopt unpredictable fighting behaviours during competitive...
