On the natural history of an introduced population of guppies (Poecilia reticulata Peters, 1859) in Germany
Artificially heated water bodies represent unusual habitats in temperate regions and form a refuge for exceptional fish communities. The Gillbach, a tributary of the river Erft in Germany, receives thermally polluted cooling water from a power plant. Here, we present data on the composition of the fish community in the Gillbach and found a high abundance of invasive species from all over the wo...
متن کاملSociability between invasive guppies and native topminnows
The role of interspecific social interactions during species invasions may be more decisive than previously thought. Research has revealed that invasive fish improve their foraging success by shoaling with native Mexican species, and potentially increase the chances of invasion success. However, do native individuals tend to associate with invaders as well? We tested the hypothesis that the two...

1 The s-wave repulsion and deeply bound pionic atoms: fact and fancy * Fits to a large data set of pionic atoms show that the 'missing' s-wave repulsion is accounted for when a density dependence suggested recently by Weise is included in the isovector term of the s-wave pion optical potential. The importance of using large data sets is demonstrated and the role of deeply bound pionic atom stat...
متن کاملGuppies
What are guppies? Guppies (Poecilia reticulata) are small tropical fish, native to the coastal streams of northeast South America. They owe their name to Robert John Lechmere Guppy who introduced them into the aquarium trade. Guppies have since become very popular aquarium fish, known for colorful males and live-bearing females. But guppies are also one of the premier model systems for the stud...
متن کاملPredation intensity does not cause microevolutionary change in maximum speed or aerobic capacity in trinidadian guppies (Poecilia reticulata Peters).
We measured maximal oxygen consumption (VO(2max)) and burst speed in populations of Trinidadian guppies (Poecilia reticulata) from contrasting high- and low-predation habitats but reared in "common garden" conditions. We tested two hypothesis: first, that predation, which causes rapid life-history evolution in guppies, also impacts locomotor physiology, and second, that trade-offs would occur b...
