Nest box provision allowed us to follow all breeding events in the population from pair forming, nest building, egg laying to fledging (∼30 days).
Horner's own research at the University of Montana, not far from the desert "badlands" where many of the best T. rex fossils have been found, has revealed that the duck-billed dinosaur, which he named Maiasaura, formed nesting colonies.
The various components of cells form nested part-whole relations, resulting in a spatial hierarchy.
Higher in the Karoo stratigraphy, sills are emplaced in the sandstone-dominated upper Ecca and Beaufort groups and form nested saucer-shaped intrusions with individual thicknesses of about 100 m and characteristic diameters of 20 60 km.
A facile one-step method is developed for the direct growth of Ni3S2 nanoplates on a conductive nickel foam, which interwove together to form nest-like highly porous microstructure.
The favourability of hydrophobic pairs e.g. IleHB-IlenHB, ValHB-ValnHB and LeuHB-IlenHB was explained by the residues adopting their most preferred χ1 and χ2 conformations, which enabled them to form nested arrangements.
During the day, when they are most vulnerable, individuals shelter inside tree holes, sometimes forming nests.
The different so-called "natural" or "monophyletic" groups form nested units, and only these are given phylogenetic names.
Like the insects, the earliest ancestors of humans formed nests: caves or campsites where 30 to 100 individuals gathered.
Naturalized, weed, and noxious species form nested subsets.
