For younger visitors, "we have a series of activities that puts kids in the position of being the migratory birds," Ms. Winter said.
Migratory songbirds are able to use geomagnetic information and celestial cues involving the position of the Sun and stars as well as the pattern of skylight polarization for orientation (e.g. Emlen, 1975; Able, 1980; Wiltschko and Wiltschko, 1995).
Skull-shape dependent changes in the position of the olfactory bulb also predict a fascinating consequence for the adult rostral migratory stream (RMS).
The position of R. similis and P. coffeae on each side of the bifurcation presumably implies that migratory endoparasitism is a prerequisite to sedentary endoparasitism and that the migratory parasitic stages of sedentary endoparasites have been lost in cyst and root-knot nematodes and yet retained as an important part of the life cycle in the "intermediate" genus Nacobbus.
The possible importation of an apparently exotic rotavirus strain such as ROMA116 into Italy is not surprising; the country's geographic position favors massive migratory flows of persons from developing countries.
After NΔ390 expression, we did not observe differences in radial positioning of MNs in either migratory stream, indicating that NΔ390 perturbs motor nucleus coalescence and not radial migration of the neurons.
Industry, however, rewards these skills handsomely—just one of the reasons that this kind of work "is highly attractive: it is addressing interesting and pressing problems; it offers good pay and benefits; it offers a path out of the migratory rat-wheel of temporary postdoctoral positions, and often even encourages research and publication in fundamental topics".
Collectively, these data argue that PKD2 does not play an important role in mediating adhesion and migratory responses of lymphocytes into, and positioning within, secondary lymphoid tissues in vivo.
We next characterized the positioning of ER PM junctions with respect to the integral elements of migratory cells.
Mexico is central to the migratory patterns of many species.
