Volumetric imaging of cellular dynamics with deep learning enhanced bioluminescence microscopy
<p>The low photon emission of known luciferases, currently limit their widespread use as contrast agents in live cell microscopy because they demand long exposure times that are prohibitive for imaging fast biological dynamics. To increase the versatility of bioluminescence microscopy as an alternative for fluorescence microscopy, we present an improved low-light microscope in combination with deep learning methods to image extremely photon-starved samples enabling subsecond exposures for timelapse and volumetric imaging. Here, we leverage a versatile training data set for deep learning based bioluminescence microscopy including paired images of noisy and ground thruth fluorescence data of body wall muscle labeled <em>Caenorhabditis elegans</em> animals. These data include light-field images and their ground truth reconstructions for training a CNN for fast light fiel deconvolution.</p>
Collective synchrony of mating signals modulated by ecological cues and social signals in bioluminescent sea fireflies
<p><span>Individuals often employ simple rules that can emergently synchronise behaviour. Some collective behaviours are intuitively beneficial, but others like mate signalling in leks occur across taxa despite theoretical individual costs. Whether disparate instances of synchronous signalling are similarly organised is unknown, largely due to challenges observing many individuals simultaneously. Recording field collectives and <em>ex situ</em> playback experiments, we describe principles of synchronous bioluminescent signals produced by marine ostracods (Crustacea; Luxorina) that seem behaviorally convergent with terrestrial fireflies, and with whom they last shared a common ancestor over 500 mya. Like synchronous fireflies, groups of signalling males use visual cues (intensity and duration of light) to decide when to signal. Individual ostracods also modulate their signal based on the distance to nearest neighbours. During peak darkness, luminescent "waves" of synchronous displays emerge and ripple across the sea floor every ~60 seconds, but such periodicity decays within and between nights after the full moon. Our data reveal these bioluminescent aggregations are sensitive to both ecological and social light sources. Because the function of collective signals is difficult to dissect, evolutionary convergence, like in the synchronous visual displays of diverse arthropods, provides natural replicates to understand the generalities that produce emergent group behaviour.</span></p>

Data from: Phenotypic evolution shaped by current enzyme function in the bioluminescent courtship signals of sea fireflies
Mating behaviours are diverse and noteworthy, especially within species radiations where they may contribute to speciation. Studying how differences in mating behaviours arise between species can help us understand how diversity is generated at multiple biological levels. The bioluminescent courtship displays of cypridinid ostracods (or sea fireflies) are an excellent system for this since amazing variety evolves while using a conserved biochemical mechanism. We find that the evolution of one aspect in this behavioural phenotype - the duration of bioluminescent courtship pulses - is shaped by biochemical function. First, by measuring light production from induced bioluminescence in 38 species, we discovered differences between species in their biochemical reactions. Then, for 16 species of which biochemical, phylogenetic, and behavioral data are all available, we used phylogenetic comparative models to show that differences in biochemical reaction are nonlinearly correlated with the duration of courtship pulses. This relationship indicates that changes to both enzyme (c-luciferase) function and usage have shaped the evolution of courtship displays, but that they differentially contribute to these phenotypic changes. This nonlinear dynamic may have consequences for the disparity of signaling phenotypes observed across species, and demonstrates how unappreciated diversity at the biochemical level can lead to inferences about behavioural evolution.
Revisiting the burglar-alarm hypothesis: a behavioral cascade mediated by dinoflagellate bioluminescence
<p>Bioluminescence is widespread among marine organisms and has evolved independently multiple times. While its specific adaptive value is diverse, bioluminescence in most cases mediates fundamental interactions between individuals (predator, prey, mates) and thus impacts ecosystem processes. One hypothesized value of bioluminescence in dinoflagellates is through the 'burglar alarm': grazers of phytoplankton will make the ambient water 'glow' as they swim, thereby attracting visual predators of the grazer, thus indirectly protecting the dinoflagellates.</p> <p>However, the most important grazers of dinoflagellates, copepods, are generally too small to elicit dinoflagellates to glow. Only individual cells captured by a copepod will flash, which in turn elicits a powerful escape response in the copepod. Here, we test a variant of this hypothesis that may work for copepods. The behavioral response of the grazer to the flashing of a captured dinoflagellate, rather than the flashing itself, attracts the attention of the grazer's flow-sensing predators.</p> <p>We demonstrate that bioluminescence in three dinoflagellates reduces the clearance- and ingestion rate of nauplii of the copepod <em>Temora longicornis</em>. The presence of bioluminescent cells also elicited an increased frequency of high-speed jumps of the grazers. The increased jump frequency elevated the detectability of the grazers to a flow-sensing predator, the copepod <em>Centropages typicus</em>, consequently leading to increased predation mortality of <em>T. longicornis</em> nauplii. The consequent behavioral cascade mediated by bioluminescence works for small grazers that cause only single cells to flash, unlike the traditional description of the burglar alarm.</p>
