Data from: A submersible, off-axis holographic microscope for detection of microbial motility and morphology in aqueous and icy environments
Sea ice is an analog environment for several of astrobiology's near-term targets: Mars, Europa, Enceladus, and perhaps other Jovian or Saturnian moons. Microorganisms, both eukaryotic and prokaryotic, remain active within brine channels inside the ice, making it unnecessary to penetrate through to liquid water below in order to detect life. We have developed a submersible digital holographic microscope (DHM) that is capable of resolving individual bacterial cells, and demonstrated its utility for immediately imaging samples taken directly from sea ice at several locations near Nuuk, Greenland. In all samples, the appearance and motility of eukaryotes were conclusive signs of life. The appearance of prokaryotic cells alone was not sufficient to confirm life, but when prokaryotic motility occurred, it was rapid and conclusive. Warming the samples to above-freezing temperatures or supplementing with serine increased the number of motile cells and the speed of motility; supplementing with serine also stimulated chemotaxis. These results show that DHM is a useful technique for detection of active organisms in extreme environments, and that motility may be used as a biosignature in the liquid brines that persist in ice. These findings have important implications for the design of missions to icy environments and suggest ways in which DHM imaging may be integrated with chemical life-detection suites in order to create more conclusive life detection packages.
DeepKymoTracker: A tool for accurate construction of cell lineage trees for highly motile cells
<p>These are the compiled models and weights of convolutional neural networks utilized in DeepKymoTracker (full version). Segmentor and Refiner form a segmentation ensemble for segmenting one cell of interest in a 96x96 patch with the cell approximately in the center of the patch. Tracker-6 is a CNN which is trained to track one cell at a time in each frame in microscope cell movies.</p>

Dataset for: Motile cilia hydrodynamics: Entrainment versus synchronisation when coupling through flow
<p>This archive contains the dataset for the article "Motile cilia hydrodynamics: Entrainment versus synchronisation when coupling through flow".</p> <p>We gathered videos of cilia dynamics from different sources. For each animal/microorganism we upload the videos in different formats depending on the source:</p> <p>- .tiffs usually in a directory, it is composed by a series of images</p> <p>- .movie a format that we use in our lab and that it is combatible with our software in Matlab to tack cilium waveform</p> <p>- .avi </p> <p>For each video we also have the results from the tracking with our software. The resuts from a single video are all in a Matlab variable that has the same name but with the extension .clclk_force</p> <p>for example for the video "filename", the results are in "filename.clclk_force".<br> In Matlab these can be loaded as force = load('filename.clclk_force','-mat');<br> For all the videos these can be directly be found in the directory cilium waveforms force files.</p>

Density-dependent patterns of multivariate selection on sperm motility and morphology in a broadcast spawning mussel
<p>Sperm cells exhibit extraordinary phenotypic variation, both among taxa and within individual species, yet our understanding of the adaptive value of sperm trait variation across multiple contexts is incomplete. For species without the opportunity to choose mating partners, such as sessile broadcast spawning invertebrates, fertilisation depends on gamete interactions, which in turn can be strongly influenced by local environmental conditions that alter the concentration of sperm and eggs. However, the way in which such environmental factors impact phenotypic selection on functional gamete traits remains unclear in most systems. Here, we analyse patterns of linear and nonlinear multivariate selection under experimentally altered local sperm densities (densities within the capture zone of eggs) on a range of functionally important sperm traits in the broadcast spawning marine mussel, <i>Mytilus galloprovincialis</i>. Specifically, we assay components of sperm motility and morphology across two fertilisation environments that simulate either sperm limitation (when there are too few sperm to fertilise all available eggs), or sperm saturation (when there are many more sperm than required for fertilisation, and the risk of polyspermy and embryonic failure is heightened). Our findings reveal that the strength, form, and targets of selection on sperm depend on the prevailing fertilisation environment. In particular, our analyses revealed multiple significant axes of nonlinear selection on sperm motility traits under sperm limitation, but only significant negative directional selection on flagellum length under sperm saturation. These findings highlight the importance of local sperm densities in driving the adaptation of sperm phenotypes, particularly those related to sperm motility, in broadcast spawning invertebrates.</p>
