Abstract Sedimentary successions exposed at basin margins as a result of late-stage inversion, uplift and erosion usually represent only limited portion the entire fill; thus, they are highly incomplete records evolution. Small satellite basins, however, might have potential recording more complete histories. The late Miocene sedimentary history Șimleu Basin, north-eastern vast Pannonian was in...

Food web recovery from mass extinction is poorly understood. We analyzed insect-feeding damage on 14,999 angiosperm leaves from 14 latest Cretaceous, Paleocene, and early Eocene sites in the western interior United States. Most Paleocene floras have low richness of plants and of insect damage. However, a low-diversity 64.4-million-year-old flora from southeastern Montana shows extremely high in...

A Framework for Ecosystem Management in the Interior Columbia Basin and Portions of the Klamath and Great Basins (Haynes and others 1996) states that a main feature of an ecosystem approach to managing natural resources is to include people, their values, and activities. The Framework acknowledges that people may make demands on ecosystems that exceed physical and biological capabilities in the...

The interaction of open and coastal oceans in a midlatitude ocean basin is investigated in light of Rossby and coastal Kelvin waves. The basinwide pressure adjustment to an initial Rossby wave packet is studied both analytically and numerically, with the focus on the low-frequency modulation of the resulting coastal Kelvin wave. It is shown that the incoming mass is redistributed by coastal Kel...

The average lifetime of a chaotic transient versus a system parameter is studied for the case wherein a chaotic attractor is converted into a chaotic transient upon collision with its basin boundary (a crisis). Typically the a~erage lifetime T depends upon the system parameter p via T —~p —p, ~ &, where p, denotes the value of p at the crisis and we caII y the critical exponent of the chaotic t...

barbus sublimus, described by coad and najafpour (1997) as a new species, was retrieved first from the aala rood, a river in khuzestan province, southwestern iran. in our latest sampling a population of this species was found, for the first time, in fahlian rood, a river in a different water basin, in fars province, southwest of iran, where no specimen of the species was collected in previous s...

This paper is concerned with stability and recursive feasibility of constrained linear receding horizon control schemes without terminal constraints and costs. Particular attention is paid to characterize the basin of attraction S of the asymptotically stable equilibrium. For stabilizable linear systems with quadratic costs and convex constraints we show that any compact subset of the interior ...
