Food Habits of the Northern Saw-whet Owl m Central Iowa: Effects of Roost Location

Correlations of Northern Saw-whet Owl Aegolius acadicus calling indices from surveys in southern Wisconsin, USA, with owl and small mammal surveys in Manitoba, Canada, 1986–2006

Nocturnal and cryptic, the Northern Saw-whet Owl (NSWO) Aegolius acadicus is a small (18–21.5 cm long) predator of small mammals, especially deer mice Peromyscus, voles (Microtus rangewide, Clethrionomys to the north), and shrews (Blarina, Sorex) (Johnsgard 1988, Swengel & Swengel 1992, Cannings 1993). This owl vocalizes primarily during its courtship and early breeding season (late winter to e...

Land slugs (Gastropoda: Pulmonata) on birds demonstrate dispersal potential

We describe the discovery of two slugs, Arion subfuscus and Deroceras reticulatum, on living adult birds captured for banding at Powdermill Nature Reserve, Rector, Pennsylvania. The presence of slugs on birds suggests that bird transport might play a role in slug dispersal. Additional keywords: Gray fieldslug, Deroceras reticulatum, dusky arion slug, Arion subfuscus, common yellowthroat, Geothl...

Analysis and Optimization of Robin - Robin Partitioned

In the solution of Fluid-Structure Interaction problems, partitioned procedures are modular algorithms that involve separate fluid and structure solvers, that interact, in an iterative framework, through the exchange of suitable transmission conditions at the FS interface. In this work we study, using Fourier analysis, the convergence of partitioned algorithms based on Robin transmission condit...
