Spotted turtle dispersal microsatellite DNA sex and site data
<p>Sex-biased dispersal is common in many animals, with male-biased dispersal often found in studies of mammals and reptiles, including interpretations of spatial genetic structure, ostensibly as a result of male-male competition and a lack of male parental care. Few studies of sex-biased dispersal have been conducted in turtles, but a handful of studies, in saltwater turtles and in terrestrial turtles, have detected male-biased dispersal as expected. We tested for sex-biased dispersal in the endangered freshwater turtle, the spotted turtle (<em>Clemmys</em> <em>guttata</em>) by investigating fine-scale genetic spatial structure of males and females. We found significant spatial genetic structure in both sexes, but the patterns mimicked each other. Both males and females typically had higher than expected relatedness at distances < 25 km, and in many distance classes greater than 25 km, less than expected relatedness. Similar patterns were apparent whether we used only loci in Hardy-Weinberg equilibrium (n = 7) or also included loci with potential null alleles (n = 5). We conclude that, contrary to expectations, sex-biased dispersal is not occurring in this species, possibly related to the reverse sexual dimorphism in this species, with females having brighter colors. We did, however, detect significant spatial genetic structure in males and females, separate and combined, showing philopatry within a genetic patch size of < 25 km in <em>C</em>. <em>guttata</em>, which is concerning for an endangered species whose populations are often separated by distances greater than the genetic patch size.</p>

Figure 2 in Ancient DNA from the extinct New Zealand grayling (Prototroctes oxyrhynchus) reveals evidence for Miocene marine dispersal
Figure 2. Time-calibrated Bayesian phylogeny of the Osmeriformes (Retropinnidae and Osmeridae) constructed from first and second codon positions of all 13 mitochondrial protein coding genes. 95% highest probability density (95% HPD) of the age estimate for each node is indicated by horizontal grey bars, with Bayesian posterior probabilities of 1.0 represented by white circles (otherwise values are reported). The x-axis represents time in millions of years before present (Mya). Red circles denote phylogenetic position and age of described retropinnid fossil material: Prototroctes modestus and P. vertex (18.7–15.9 Myr; Schwarzhans et al., 2011), Navidadichthys mirus (18–17 Myr; Schwarzhans et al., 2021), Prototroctes oxyrhynchus (0.71–0.62 Myr; McDowall et al., 2006) – we also indicate Speirsaenigma lindoei (57 Myr; Wilson & Williams, 1991), which was used to constrain the minimum age of crown Osmeridae. Timing of relevant geological events, such as rifting of the Zealandian and Australian continental blocks (Cooper & Millener, 1993) and maximum marine inundation (i.e. 'Oligocene drowning'; Mildenhall et al., 2014) are highlighted. Continental distribution of retropinnid lineages are indicated by outline maps. Extinct taxa are denoted †.

Cell behaviors underlying Myxococcus xanthus aggregate dispersal
<p>The soil bacterium Myxococcus <em>xanthus</em> is a model organism with a set of diverse behaviors. These behaviors include the starvation-induced multicellular development program, in which cells move collectively to assemble multicellular aggregates. After initial aggregates have formed, some will disperse, with smaller aggregates having a higher chance of dispersal. Initial aggregation is driven by two changes in cell behavior: cells slow down inside of aggregates and bias their motion by reversing direction less frequently when moving towards aggregates. </p> <p>However, the cell behaviors that drive dispersal are unknown. Here we use fluorescent microscopy to quantify changes in cell behavior after initial aggregates have formed. We observe that after initial aggregate formation, cells adjust the bias in reversal timings by initiating reversals more rapidly when approaching unstable aggregates. Using agent-based modeling, we then show dispersal is predominantly generated by this change in bias, which is strong enough to overcome slowdown inside aggregates. Notably, the change in reversal bias is correlated with the nearest aggregate’s size, connecting cellular activity to previously observed correlations between aggregate size and fate. To determine if this connection is consistent across strains, we analyze a second M. <em>xanthus</em> strain with reduced levels of dispersal. We find that far fewer cells near smaller aggregates modified their bias. This implies that aggregate dispersal is under genetic control, providing a foundation for further investigations into the role it plays in the life cycle of M. <em>xanthus</em>.</p>
Dynamic coupling and spin-wave dispersions in a magnetic hybrid system made of an artificial spin-ice structure and an extended NiFe underlayer
<p>We present a combined experimental and numerical study of the spin-wave dispersion in a NiFe artificial spin-ice (ASI) system consisting of an array of stadium-shaped nanoislands deposited on the top of a continuous NiFe film with non-magnetic spacer layers of varying thickness.<br> The spin-wave dispersion, measured by wavevector resolved Brillouin light scattering spectroscopy in the Damon–Eshbach configuration, consists of a rich number of modes, with either stationary or propagating character. We find that the lowest frequency mode displays a bandwidth of ∼0.5 GHz, which is independent of the presence of the film underneath. On the contrary, the Brillouin light scattering intensity of some of the detected modes strongly depends on the presence of the extended thin-film underlayer. Micromagnetic simulations unveil the details of the dynamic coupling between the ASI lattice and film underlayer. Interestingly, the ASI lattice facilitates dynamics of the film either specific wavelengths or intensity modulation peculiar to the modes of the ASI elements imprinted in the film. Our results demonstrate that propagating spin waves can be modulated at the nanometer length scale by harnessing the dynamic mode coupling in the vertical, i.e., the out-of-plane direction of suitably designed magnonic structures.</p>
