Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Properties of bars in the local universe

open access: yes, 2008
We studied the fraction and properties of bars in a sample of about 3000 galaxies extracted from SDSS-DR5. This represents a volume limited sample with galaxies located between redshift 0.01-20, and inclination i < 60.

Cowbirds use conspecific social information to detect host nests in the wild

open access: yesIbis, EarlyView.
Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

Living with Neighbors. V. Better-aligned Spiral+Spiral Galaxy Pairs Show Stronger Star Formation

open access: yesThe Astrophysical Journal
Enhanced star formation (SF) with star-forming neighboring galaxies bolsters the hydrodynamical contributions during paired interactions. Although the relative spin orientation between interacting galaxies can influence this effect, it has not been ...

Quantifying the FIR interaction enhancement in paired galaxies [PDF]

open access: yes
The Catalog of Isolated Pairs of Galaxies in the Northern Hemisphere, by Karachentsev (1972), was studied and a well-matched comparison sample taken from the Catalog of Isolated Galaxies, by Karachentseva (1973), in order to quantify the enhanced FIR ...

Innovation Diffusion Among Case‐Based Decision‐Makers

open access: yesJournal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper analyzes a model of innovation diffusion with case‐based individuals a la Gilboa and Schmeidler, who decide whether to consume an incumbent or a new product based on their and their social neighbors' previous consumption experiences. I analyze how diffusion patterns change with individual characteristics, innovation characteristics,

The molecular gas content throughout the low-z merger sequence

open access: yesThe Open Journal of Astrophysics
Exploiting IRAM 30 m CO spectroscopy, we find that SDSS post-merger galaxies display gas fractions and depletion times enhanced by 25-50\%, a mildly increased CO excitation, and standard molecular-to-atomic gas ratios, compared to non-interacting ...

Dynamics of Galaxy Interactions [PDF]

open access: yes, 1998
This review briefly and very informally summarizes some of my ongoing research. One unifying theme in my work is the use of computers to bridge the gap between human and astronomical time-scales. Galactic collisions are an example; the dynamics of interacting galaxies can be visualized with numerical simulations.
