“…For instance, the genus Necturus comprises large paedomorphic salamanders, and the five Necturus species in our dataset experience mean annual water temperatures between 14°C and 18°C. However, the actual temperature experienced by these salamanders is much lower, as they are active only during coolest months of the year, generally when water temperature is between 7°C and 9°C, and either aestivate or are inactive during summer when water temperature is warm (Braswell and Ashton 1985;Petranka 1998;Brenes and Ford 2006;Beattie et al 2017). A constant water temperature of 20°C therefore appears to be an extreme temperature to sustain activity among lungless, aquatic species, and we argue these extreme temperatures have played a role in the evolution of small size among the paedomorphic Eurycea.…”

Bergmann's rule is the propensity for species-mean body size to decrease with increasing temperature. Temperature-dependent oxygen limitation has been hypothesized to help drive temperature-size relationships among ectotherms, including Bergmann's rule, where organisms reduce body size under warm oxygen-limited conditions, thereby maintaining aerobic scope. Temperature-dependent oxygen limitation should be most pronounced among aquatic ectotherms that cannot breathe aerially, as oxygen solubility in water decreases with increasing temperature. We use phylogenetically explicit analyses to show that species-mean adult size of aquatic salamanders with branchial or cutaneous oxygen uptake becomes small in warm environments and large in cool environments, whereas body size of aquatic species with lungs (i.e., that respire aerially), as well as size of semiaquatic and terrestrial species do not decrease with temperature. We argue that oxygen limitation drives the evolution of small size in warm aquatic environments for species with aquatic respiration. More broadly, the stronger decline in size with temperature observed in aquatic versus terrestrial salamander species mirrors the relatively strong plastic declines in size observed previously among aquatic versus terrestrial invertebrates, suggesting that temperature-dependent oxygen availability can help drive patterns of plasticity, micro- and macroevolution.

“…Blue crabs ( Callinectes sapidus ) were recorded actively feeding on dreissenids in the Hudson River , causing mussels populations to crash near Catskill (New York, USA) in 1992 (Molloy et al, 1994 ). Dreissena was found in the guts of the mudpuppy salamander ( Necturus maculosus ), a declining Laurentian Great Lakes native species (Beattie et al, 2017 ). Experiments in The Zoological Garden of Osnabrück (Germany) showed that mongooses ( Mungos mungo ) and the oriental small-clawed otters ( Aonyx cinerea ) can feed on zebra mussels; raccoons ( Procyon lotor ) prefer zebra mussels over other food items, while Arctic foxes ( Vulpes lagopus ) feed on mussels reluctantly (Schernewski et al, 2019 ).…”

Ecosystem services provided by the exotic bivalves Dreissena polymorpha, D. rostriformis bugensis, and Limnoperna fortunei

The ecosystem services approach to conservation is becoming central to environmental policy decision making. While many negative biological invasion-driven impacts on ecosystem structure and functioning have been identified, much less was done to evaluate their ecosystem services. In this paper, we focus on the often-overlooked ecosystem services provided by three notable exotic ecosystem engineering bivalves, the zebra mussel, the quagga mussel, and the golden mussel. One of the most significant benefits of invasive bivalves is water filtration, which results in water purification and changes rates of nutrient cycling, thus mitigating the effects of eutrophication. Mussels are widely used as sentinel organisms for the assessment and biomonitoring of contaminants and pathogens and are consumed by many fishes and birds. Benefits of invasive bivalves are particularly relevant in human-modified ecosystems. We summarize the multiple ecosystem services provided by invasive bivalves and recommend including the economically quantifiable services in the assessments of their economic impacts. We also highlight important ecosystem disservices by exotic bivalves, identify data limitations, and future research directions. This assessment should not be interpreted as a rejection of the fact that invasive mussels have negative impacts, but as an attempt to provide additional information for scientists, managers, and policymakers.
