Ecologically mediated differences in electric organ discharge drive evolution in a sodium channel gene in South American electric fishes

<p>Active electroreception — the ability to detect objects and communicate with conspecifics via the detection and generation of electric organ discharges (EODs) — has evolved convergently in several fish lineages. South American electric fishes (Gymnotiformes) are a highly species-rich group, possibly in part due to evolution of an electric organ (EO) that produces diverse EODs. Neofunctionalization of a voltage-gated sodium channel accompanied the evolution of electrogenic tissue from muscle and resulted in a novel gene (scn4aa) uniquely expressed in the EO. Here, we investigate the link between variation in scn4aa and differences in EOD waveform. We combine gymnotiform scn4aa sequences encoding the C-terminus of the Nav1.4a protein with biogeographic data and EOD recordings. We test whether physiological transitions among EOD types accompany differential selection pressures on scn4aa. We found positive selection on scn4aa coincided with shifts in EOD types. Species that evolved in the absence of predators, which likely selected for reduced EOD complexity, exhibited increased scn4aa evolutionary rates. We model mutations in the protein that may underlie changes in protein function and discuss our findings in the context of gymnotiform signalling ecology. Together, this work sheds light on the selective forces underpinning major evolutionary transitions in electric signal production.</p>

Spectrum and Temperature Evolution of Lightning Channel and Dependence on Discharge Feature

<p>Temperature is one of the crucial parameters reflecting the energy and current transfer characteristics in the lightning discharge channel. According to the spectra of eight return strokes recorded simultaneously by two high-speed slitless spectrographs with different time resolutions, the spectral-structure and temperature evolution of the return stroke channels over time was quantitatively analyzed. Different from the previous report, one of the spectrographs has recorded the ionic lines in the spectra within approximately 200 microseconds during the return stroke. The ionic line intensity decayed rapidly with time as the current declined, while the atomic line intensity decreased more slowly. The spectral-structure evolution characteristics indicate that the ionic lines in the spectra existed throughout the discharge current process (including the continuing current (CC) stage). Additionally, it further suggests that the ionic line intensities are associated with the discharge currents and that their radiation mechanism is closely related to the collision excitation under the action of strong currents. The temperature calculated using the ionic lines can reflect the thermodynamic properties of the current-carrying channel. The temperature calculated using atomic lines is significantly lower than that calculated using the ionic lines in the same spectrum. The radiation mechanism of the atomic lines differs from that of the ionic lines. Compared with the decay of the ionic-line intensity, the decline of the channel temperature is slower, and there is even a slight increase in the CC stage. This property reflects the effect of the current action integral.</p>

Data from: Experimental assessment of downstream environmental DNA patterns under variable fish biomass and river discharge rates

<p><span>The development of environmental DNA (eDNA) methods towards implementation as a cost-effective, nonlethal tool for fish biomonitoring in lotic environments requires insights on the temporal and spatial distribution of eDNA in river systems. Yet, little is known on how downstream eDNA dispersal is affected by the combination of river discharge and source biomass effects. In this study, we aimed at unravelling the effect of source- and system-specific processes on the stream reach of eDNA. We used a longitudinal cage study in two river sections characterized by a significantly different discharge rate, where two invasive and two native fish species were introduced under two contrasting biomass treatments. Using droplet digital PCR (ddPCR) analyses, we found that eDNA concentrations become strongly reduced 2 km downstream from the source, an effect that is strengthened with increasing river discharge and coinciding dilution effects. Higher discharge rates resulted in equal or even higher detection probabilities at increasing distance from the source. The introduction of high fish stock biomass resulted in an increase of eDNA concentrations, as well as detection probabilities and in parallel reduced the stochasticity of the measurements. A peak in eDNA concentrations at a downstream distance ranging between 300 m and 2 km confirms the complexity of plume-shaped downstream eDNA patterns. Our results showed interspecific variation in eDNA emission and suggest species-specific differences in eDNA persistence. This study underlines the impact of both river discharge rate and source biomass on downstream eDNA detection and dispersal patterns. </span></p>
