“…Most likely, the large amount of inter-individual variation in this study obscured significant relationships between burrowing and temperature. Waller et al (1999) noted that movements and righting of several unionid species increased in intensity by 10% and 8%, respectively, on average for every 1 C increase in temperature between 7…”

“…Because significant differences in burrowing behaviors exist among temperatures, we expect that environmental changes at both the local and regional scale will affect the behavior of mussels. Feeding (Yeager et al 1994), reproductive (Amyot and Downing 1998), and display behaviors (Waller et al 1999) are influenced by an individual's orientation and burrowing ability, which can be altered by changes in water temperature. There are a number of ways the thermal regimes of water bodies can be altered so as to influence mussel burrowing.…”

Despite the limited mobility of freshwater mussels, locomotion, especially burrowing, may be a critical part of their ecology. The effects of temperature on burrowing activities in freshwater mussels have not received much attention. In the laboratory, we studied the effects of three temperatures (ca. 10, 20, and 30 C) on mussel burrowing behaviors and performance. Behaviors assessed include latency to valve opening, latency until the foot becomes extended, and latency until burrowing. We also quantified burrowing performance by measuring burrowing duration. Mussels were significantly more likely to extend their foot and ultimately burrow at the highest experimental temperature. Burrowing performance was not significantly impacted, with burrowing duration being largely unaffected by temperature. This pattern suggests a hypothetical mechanism, whereby if some temperature threshold is reached that allows burrowing, the animal burrows normally. If that threshold is not attained, the mussel will not explore its environment nor burrow. The implications of this work are important to mussel biology and conservation because the thermal regimes of aquatic systems are changing with other global temperatures and smaller-scale effects are common, such as alteration of thermal regimes due to the outflow from dams. If mussels in these systems are affected they are likely, in turn, to affect community and ecosystem ecology in their native habitats.

“…Faced with multiple stressors, mainly of anthropogenic origin such as habitat loss, degradation and fragmentation, mussels have their Achilles' heel in a suite of traits that make them unable to adjust to these changes (Watters, 2000;Hastie et al, 2003;Lydeard et al, 2004, Galbraith et al, 2010. First of all adult mussels have limited displacement ability (Green et al, 1985;Amyot and Downing, 1997;Waller et al, 1999) that prevents them to escape adverse conditions. Mussel life histories vary widely among and within species but, generally, as all long-lived species, mussels grow slowly, have delayed maturity and most species have a lower fecundity than previously believed for the group (Haag, 2013).…”

When and how? Freshwater mussel recolonization in Lake Orta

et al. 2016

Thanks to a video posted on a social network, live mussels of Unio elongatulus, have been recorded from Lake Orta (Italy) over one century after the last (and only) report. With its long and well documented history of pollution, Lake Orta offers the opportunity to document the post-extirpation recovery of freshwater unionid mussels. This case evidences that recovery/recolonization is possible despite a high devastation in the past, and permits to evaluate how fast recolonization may occur, in which way, and in what conditions. The answer to the how fast was sought by estimating the age of the larger and seemingly older individuals of the population. To address the in which way we compared the haplotypes of Lake Orta specimens of Unio elongatulus (the only species present) with those of surrounding populations. We concluded that, since Lake Orta lacks a direct connection with the putative source populations, colonizing mussels were almost certainly transported by fish carrying glochidia that were used for lake restocking after liming. Data from the long-term monitoring of water chemistry and sediments have allowed defining what conditions proved to be suitable for survival making possible the start of mussels recovery. But not only water and sediment quality matters for mussels recovery, which was delayed by nearly ten years after the reappearance of fish. This delay reflects the need of the whole trophic chain to be reestablished to allow the survival of the suitable and healthy host-fish populations necessary for mussels reproduction.

In some studies, moments of force, which depend on shell morphology, were found to affect locomotion of various gastropods (e.g.…”

SUMMARYAlthough zebra mussels (Dreissena polymorpha) initially colonized shallow habitats within the North American Great Lakes, quagga mussels (Dreissena bugensis) are becoming dominant in both shallow-and deep-water habitats. Shell morphology differs among zebra, shallow quagga and deep quagga mussels but functional consequences of such differences are unknown. We examined effects of shell morphology on locomotion for the three morphotypes on hard (typical of shallow habitats) and soft (characteristic of deep habitats) sedimentary substrates. We quantified morphology using the polar moment of inertia, a parameter used in calculating kinetic energy that describes shell area distribution and resistance to rotation. We quantified mussel locomotion by determining the ratio of rotational (K rot ) to translational kinetic energy (K trans ). On hard substrate, K rot :K trans of deep quagga mussels was fourfold greater than for the other morphotypes, indicating greater energy expenditure in rotation relative to translation. On soft substrate, K rot :K trans of deep quagga mussels was approximately one-third of that on hard substrate, indicating lower energy expenditure in rotation on soft substrate. Overall, our study demonstrates that shell morphology correlates with differences in locomotion (i.e. K rot :K trans ) among morphotypes. Although deep quagga mussels were similar to zebra and shallow quagga mussels in terms of energy expenditure on sedimentary substrate, their morphology was energetically maladaptive for linear movement on hard substrate. As quagga mussels can possess two distinct morphotypes (i.e. shallow and deep morphs), they might more effectively utilize a broader range of substrates than zebra mussels, potentially enhancing their ability to colonize a wider range of habitats.Key words: biological invasions, bivalve, functional morphology, Great Lakes, kinetic energy, locomotion, mollusc, moment of inertia, sediment. THE JOURNAL OF EXPERIMENTAL BIOLOGY Mussel morphology and movementA shell morphology that facilitates locomotion across particular substrate types might affect fitness and survival of zebra and quagga mussels on those substrates. Zebra mussels are known to move in response to various environmental factors (e.g. light, nitrogenous waste, oxygen and substrate type) that influence habitat selection and survival (see Burks et al., 2002;Kilgour and Mackie, 1993;Kobak, 2001;Kobak and Nowacki, 2007;Marsden and Lansky, 2000;Toomey et al., 2002).The objective of this study was to directly examine the effects of shell morphology on locomotion of different mussel morphotypes (i.e. zebra, shallow quagga and deep quagga mussels) on hard versus soft sedimentary substrates. We determined the effects of shell shape on locomotory function by calculating translational and rotational kinetic energy (K trans and K rot , respectively) for zebra and quagga mussels moving across hard and soft substrate types. K trans and K rot directly account for effects of shell size and shape on locomotory function, as K tr...
