Data from: Duration of the parasitic phase determines subsequent performance in juvenile freshwater pearl mussels (Margaritifera margaritifera)
Host–parasite systems have been useful in understanding coevolutionary patterns in sympatric species. Based on the exceptional interaction of the long-lived and highly host-specific freshwater pearl mussel (FPM; Margaritifera margaritifera) with its much shorter-lived host fish (Salmo trutta or Salmo salar), we tested the hypotheses that a longer duration of the parasitic phase increases fitness-related performance of mussels in their subsequent post parasitic phase, and that temperature is the main factor governing the duration of the parasitic phase. We collected juvenile mussels from naturally and artificially infested fish from eight rivers in Norway. Excysted juvenile mussels were maintained separately for each collection day, under similar temperature and food regimes, for up to 56 days. We recorded size at excystment, post excystment growth, and survival as indicators of juvenile fitness in relation to the duration of the parasitic phase. We also recorded the daily average temperatures for the entire excystment period. We observed strong positive relationships between the length of the parasitic phase and the post parasitic growth rate, size at excystment and post parasitic survival. Temperature was identified as an important factor governing excystment, with higher temperatures decreasing the duration of the parasitic phase. Our results indicate that juvenile mussels with the longest parasitic phase have better resources (larger size and better growth rate) to start their benthic developmental phase and therefore to survive their first winter. Consequently, the parasitic phase is crucial in determining subsequent survival. The temperature dependence of this interaction suggests that climate change may affect the sensitive relationship between endangered FPMs and their fish hosts.

Microhabitat temperature variation combines with physiological variation to enhance thermal resilience of the intertidal mussel Mytilisepta virgata
<p>1. Predicting the effects of rising temperature entails measuring both habitat thermal characteristics and the physiological variation of the species as it relates to this microhabitat variation; these two types of measurements can generate what is termed a "physiological landscape" for the species. Mapping the micro-scale physiological landscape across space and time, rather than relying on large-scale averages of temperature and means of thermal limits in a species, can allow more accurate estimates of an organism's sensitivity to temperature change and support development of more refined models of the impacts of anthropogenic climate change that have higher predictive power.</p> <p>2. We thus continually monitored the body (operative) temperature of the intertidal mussel Mytilisepta virgata in both sun-exposed and shaded microhabitats and determined the seasonal variations of cardiac performance of field-acclimatized and laboratory-acclimated mussels from different microhabitats for calculating the thermal sensitivity, as indicated by the difference between the maximum ambient temperature and an individual's upper thermal limit (thermal safety margin, TSM), in each microhabitat and each month.</p> <p>3. The mussels experienced divergent thermal stress, in average temperature, acute and chronic thermal stress, and thermal predictivity among different microhabitats, and presented high spatial-temporal variations of cardiac function as results of seasonal acclimatization and inter-individual variations. Results of TSMs indicated that the thermal sensitivities of the mussels to high temperature were season- and microhabitat-specific, and the mussels in the shaded microhabitats were predicted to survive the hottest summer temperatures; however, some individuals in the sun-exposed microhabitats experienced temperatures above their sublethal temperature.</p> <p>4. With the large, high-resolution dataset of thermal environmental characteristics and the cardiac performances with high variations, we were able to integrate the effects of synchronized changes in microenvironmental temperatures and cardiac thermal responses and thereby characterize the physiological landscape of thermal sensitivity. The complex physiological landscape that exists in the intertidal zone must be taken into account when predicting effects of changes in environmental temperature, such as those occurring with global climate change.</p>
The mussel tracker dataset
<p>This dataset contains observations of mussel (<em>Mytilus edulis</em>) trajectories in an experimental setting. We were interested by one particular behavioral trait of this species, which have the capacity to crawl with the foot to avoid disturbance and choose a better fixation place.</p> <p>Mussels were placed in a 32 x 42 cm box, immersed in a bigger 700 liters tank equipped with a small underwater pump, for water recirculation. Mussels were young individuals collected in the wild, in Normandy (France). A small action camera was placed over the tank to make a movie of the mussel tracks, taking photos at a frequency of one image per minute. We tested 3 mussel densities (25, 50 or 75 individuals per experiment), each with three replicates. The runs lasted from 4 to 6 hours. We corrected the photos to straighten up for fish-eye effect and reframe them. We then pointed the different individuals with an image treatment open-source software to measure length, and determine x and y mussel position every minute.</p> <p>The dataset contains 137913 observations and 5 columns. First column is the individual id-code, second column contains individual length in centimeters, third column bears the time-information, and last x and y columns present the x and y positioning in cm, of the individual at time t.</p>
