A common terminology to unify research and conservation of coralline algae and ...
Jardim, Victor L.; Grall, Jacques; Barros‐Barreto, M. Beatriz; Bizien, Anaëlle; Benoit, Thomas; Braga, Juan C.; Brodie, Juliet; Burel, ThomasLinguistic uncertainty is a prime source of uncertainty pervading ecology and conservation. Coralline algae are a widespread and diverse group of calcifying red macroalgae that underpin coastal ecosystem function and service provision. Recent increasing interest in coralline algae in the scientific literature has revealed a diverse but confusing terminology at organism to habitat scales. Coralline algal researc...
Withstanding the heat: resilience of free-living coralline algae to marine heat...
Nannini, Matteo; Cerpelloni, Martina; Gaspar, Tainá L.; Peña, Viviana; Tuya, Fernando; Peñas, Julio; Rio, Jesús del; Vieira Mourato, CarolinaMarine heatwaves (MHWs) can severely impact benthic ecosystems, driving major ecological shifts. As they become longer, more frequent, and intense, MHWs are emerging as a dominant threat to marine biodiversity. Yet, their potential effects on coralline algal beds (CABs, including rhodolith beds), habitats of critical ecological importance, remain largely unknown. This study investigated the physiological respon...
Photosynthetic response to a winter heatwave in leading and trailing edge popul...
Kolzenburg, Regina; Ragazzola, Federica; Tamburello, Laura; Nicastro, Katy; McQuaid, Christopher D.; Zardi, GerardoMarine heatwaves (MHWs) caused by anthropogenic climate change are becoming a key driver of change at the ecosystem level. Thermal conditions experienced by marine organisms across their distribution, particularly towards the equator, are likely to approach their physiological limits, resulting in extensive mortality and subsequent changes at the population level. Populations at the margins of their species' di...
Positive species interactions structure rhodolith bed communities at a global s...
Bulleri, Fabio; Schubert, Nadine; Hall‐Spencer, Jason M.; Basso, Daniela; Burdett, Heidi L.; Francini‐Filho, Ronaldo B.; Grall, Jacques; Horta, Paulo A.Rhodolith beds are diverse and globally distributed habitats. Nonetheless, the role of rhodoliths in structuring the associated species community through a hierarchy of positive interactions is yet to be recognised. In this review, we provide evidence that rhodoliths can function as foundation species of multi-level facilitation cascades and, hence, are fundamental for the persistence of hierarchically structur...
Levelling-up rhodolith-bed science to address global-scale conservation challenges
Tuya, Fernando; Schubert, Nadine; Aguirre, Julio; Basso, Daniela; Bastos, Eduardo O.; Berchez, Flávio; Bernardino, Angelo F.; Bosch, Néstor E.Global marine conservation remains fractured by an imbalance in research efforts and policy actions, limiting progression towards sustainability. Rhodolith beds represent a prime example, as they have ecological importance on a global scale, provide a wealth of ecosystem functions and services, including biodiversity provision and potential climate change mit-igation, but remain disproportionately understudied,...
Understanding the margin squeeze: differentiation in fitness-related traits bet...
Kolzenburg, Regina; Nicastro, Katy; McCoy, Sophie J.; Ford, Alex T.; Zardi, Gerardo; Ragazzola, FedericaAssessing population responses to climate-related environmental change is key to understanding the adaptive potential of the species as a whole. Coralline algae are critical components of marine shallow water ecosystems where they function as important ecosystem engineers. Populations of the calcifying algae Corallina officinalis from the center (southern UK) and periphery (northern Spain) of the North Atlantic...
The future of the northeast Atlantic benthic flora in a high CO2 world
Brodie, Juliet; Williamson, Christopher J.; Smale, Dan A.; Kamenos, Nicholas A.; Mieszkowska, Nova; Santos, Rui; Cunliffe, Michael; Steinke, MichaelSeaweed and seagrass communities in the northeast Atlantic have been profoundly impacted by humans, and the rate of change is accelerating rapidly due to runaway CO2 emissions and mounting pressures on coastlines associated with human population growth and increased consumption of finite resources. Here, we predict how rapid warming and acidification are likely to affect benthic flora and coastal ecosystems of ...
