Intra-egg oxygen dissolved in Octopus maya embryos
<p>Those data show, for the first time, oxygen concentration levels in the perivitelline liquid of Octopus maya embryos. Data are shown as a percentage of oxygen saturation, measured at 24°C, using a Needle-type oxygen microsensor (Loligo Systems, Denmark). The sensor was placed in an automated micromanipulator (PreSense, Germany), and the eggs were placed in a supporting device at 38° of inclination. In such form, the sensor was inserted in the perivitelline liquid, registering the oxygen dissolved inside the eggs. The final oxygen level was recorded between one and three min after the sensor insertion. Data of oxygen dissolved during embryo development were grouped as blastulation, organogenesis, activation, and growth phases. A negative power curve was constructed for the relationship between oxygen dissolved in the perivitelline liquid and embryo development</p>
C.elegans embryo early development tracked with TrackMate
<p><em>C.elegans</em> embryo early development.</p> <p>This movie is a maximum-intensity projection (MIP) of a longer movie used initially in:</p> <blockquote> <p>Tinevez JY, Dragavon J, Baba-Aissa L, Roux P, Perret E, Canivet A, Galy V, Shorte S. A quantitative method for measuring phototoxicity of a live cell imaging microscope. Methods Enzymol. 2012;506:291-309. doi: 10.1016/B978-0-12-391856-7.00039-1.

Toxicogenomic profiles of neuronal targeting insecticides in zebrafish embryos as non-target aquatic vertebrate model
<p>We have conducted semi-static exposure studies with six neuronal targeting insecticides on fertilized zebrafish (Danio rerio) eggs, similar to the OECD 236 guideline for the 96h zebrafish embryo toxicity test. The aim of these transcriptomic profiling experiments was to screen for ecotoxicogenomic fingerprints in zebrafish (Danio rerio) embryos as aquatic vertebrate non-target model exposed to sub lethal concentrations of pesticides.

Figure 1 in Embryo retention, character optimization, and the origin of the extra-embryonic membranes of the amniotic egg
Figure 1. Sarcopterygian phylogeny showing an optimization of embryo retention (character 1), as previously advocated by Laurin and Girondot (1999). The only modification is that all terminal taxa are in the present tree, instead of collapsing Monotremata and Theria into Mammalia, to better match the character distribution shown in Table I, and that Actinistia is coded as unknown (as shown by the absence of a data box below that taxon).
