The effect of simulated marine heatwaves on green-lipped mussels, Perna canaliculus: A near-natural experimental approach
<p>Marine heatwaves (MHW) are projected for the foreseeable future, affecting aquaculture species, such as the New Zealand green-lipped mussel (<em>Perna canaliculus</em>). Thermal stress alters mussel physiology highlighting the adaptive capacity that allows survival in the face of heatwaves. Within this study, adult mussels were subjected to three different seawater temperature regimes: 1) low (sustained 18°C), 2) medium MHW (18 - 24°C, using a +1°C per week ramp) and high MHW (18 - 24°C, using a +2°C per week ramp). Sampling was performed over 11 weeks to establish the effects of temperature on <em>P. canaliculus</em> survival, condition, specific immune response parameters, and the haemolymph metabolome. The transient 25.5-26.5°C exposure resulted in 61% mortality, with surviving animals showing a metabolic adjustment within the aerobic energy production system, enabling the activation of molecular defence mechanisms. Utilisation of immune functions were seen within the cytology results where temperature stress affected the percentage of superoxide-positive haemocytes and haemocyte counts. From the metabolomics results an increase in antioxidant metabolites was seen in the high MHW survivors, possibly to counteract molecular damage. In the high MHW exposure group, mussels utilised anaerobic metabolism in conjunction with aerobic metabolism to produce energy, to uphold biological functions and survival. The effect of exposure time was mainly seen on very long-, and long chain fatty acids, with increases observed at weeks seven and eight. These changes were likely due to the membrane storage functions of fatty acids, with decreases at week eleven attributed to energy metabolism functions. This study supports the use of integrated analytical tools to investigate the response of marine organisms to heatwaves. Indeed, specific metabolic pathways and cellular markers are now highlighted for future investigations aimed at targeted measures. This research contributes to a larger program aimed to identify resilient mussel traits and support aquaculture management.</p>
Perna perna metadata and genotypic data
<p>Studies investigating gene flow in sessile or sedentary marine species typically draw conclusions about larval dispersal by investigating genetic structure of adults. Here, we generated microsatellite data from adults, recruits, settlers and planktonic larvae of the brown mussel, <em>Perna</em> <em>perna</em>, from the south-east coast of South Africa, and identified a consistent mismatch in genetic structure between the adults and all earlier life stages. While adults could be assigned to two major geographical groups (western and eastern), most of the early-stage mussels were strongly affiliated with the eastern group. This result suggests that few of the early-stage individuals present in the western portion of the sampling range will become part of the adult population. Our findings highlight the importance of post-settlement processes as key drivers of population structure and caution against the exclusive use of genetic data generated from adults to assess population connectivity facilitated by the dispersal of planktonic propagules.</p>
