The observed nested sequence architecture of the Upper Mesaverde Group is considered to be controlled by variation in subsidence rate related to the emplacement and erosion of thrust sheets in the adjacent Sevier orogenic belt.
In contrast, in the presence of noise with standard deviation 150 pA we observed nested gamma frequency synaptic activity with timing that was consistent between theta cycles.
We discussed how the evolution of host range in fungal species may account for the observed nested patterns.
We lagged the effect of x on N as the variability of x influences juvenile turtles, only a portion of which breed λ years later and are observed nesting.
Nest failure rates high: 1 out of 4 of Skutch's (1969) and 1 of 6 of Willis and Oniki's (1972) observed nests fledged young; 9 observed nests failed in a study on BCI (Robinson et al. 2005), and 4 observed nests failed in Costa Rica (Young et al. 2008).
They could not find breeding sites elsewhere in the state, but observed nesting birds and chicks in the HEZ.
The researchers, who described their work in The Proceedings of the Royal Society: Biology Letters, observed nests with up to three chicks at a pond near St. Etienne in central France.
The nests of birds, by far the most commonly observed nest builders, are highly varied, from no real structure at all (e.g., those of falcons, owls, many seabirds and shorebirds) to the elaborate retort-shaped nests of weavers (Ploceidae), woven with grass strands tied with knots.
In Sonora, Mexico, eagles have been observed nesting on top of Hecho catcuses (Pachycereus pectinaboriginum).
In 1987, a small population of common starlings was observed nesting in gardens in the city of Buenos Aires.
Moreover, individual specimens (males) that were observed nesting (Ben-Tzvi, unpublished data) suggest that, for this fish, due to their density at the study site, the harem is not essential for reproduction and, thus, finding a future mate should not be a factor influencing the settlers' decision.
