Xenopus

In Xenopus, ontogeny of olfactory and accessory olfactory (vomeronasal) organs (Quinzio & Reiss, 2018), anatomy (Foske, 1934; Altner, 1962), fine structure of olfactory neuroepithelia of nasal chambers (Oikawa et al, 1998), olfactory receptors (Freitag et al, 1995; Suzuki etal., 1999), neuroepithelial axonal projections to the main olfactory bulb, and vomeronasal pathways to the accessory olfactory bulb (Saito & Taniguchi, 2000) are described in great detail.

However, in some species, the polyadenlyation signal is not present such as CypA of Blatella (Martinez-Gonzalez and Hegardt, 1995) and CypA of Xenopus laevis (Masse et al., 2004).

Unlike previous research, here the BnPIP-like gene was induced into and expressed in yeast, rather than Xenopus laevis oocytes.

In addition, AQP5 (AQP5a) and AQP5L (AQP5b) were identified from Xenopus tropicalis Gray, 1864, and AQP5 was localized to the apical membrane of luminal epithelial cells of the urinary bladder in dehydrated Xenopus.

Peroxisome proliferator-activated receptors (PPAR) are members of the nuclear receptor superfamily and was first identified in xenopus (Krey et al., 1993).

Similar jaw muscle anatomy is also characteristic of suspension feeding pipid tadpoles (e.g., Xenopus; Vera-Candioti, 2007; Ziermann and Olson, 2007) where feeding kinematics of the orbitohyoideus and interhyoideus have been examined (Wassersug and Yamashita, 2001; Ryerson and Deban, 2010).

There are only 3 other springtail species recorded from ant nests (without citation of the ant species) in Brazil: Mastigoceras camponoti Handschin, Seira edmanni (Stach) and Cyphoderodes xenopus Borner, and all of them are springtail species originally described from Brazil (Abrantes et al.

The African clawed frog (Xenopus laevis) is a smooth-skinned frog with a flattened body, small head, blunt snout, and small upturned eyes with no lids (Stebbins, 2003; Dodd, 2013).

The African clawed frog (Xenopus laevis) has established invasive populations outside of its natural range, including throughout southern California; however, little is known concerning its impacts on native ecosystems.

It is well known that lithium chloride is effective for axis perturbation of Xenopus laevis.
