TL;DR: The user interface is simple and homogeneous among all the programs; this contributes to making the use of ADE-4 very easy for non- specialists in statistics, data analysis or computer science.

TL;DR: This work combined three published data sets of stream macroinvertebrate abundances collected at three spatial scales with a database of functional species traits to evaluate the accuracy of community descriptions through the stability of such descriptions, the degree of similarity of site ordinations, and the overall community structure expressed at each taxonomic level.

TL;DR: In this paper, the authors identify four distinct movement behaviors of anguillid eels: "founders" that colonize rivers until they settle in the first available suitable habitat they encounter, "pioneers" which migrate upstream to the upper boundaries of the system, "home range dwellers" and "nomads" which are erratic eels that perform a general upstream shift as they search for suitable areas to forage or to settle.

TL;DR: In this paper, the authors report patterns of temporal variation in the recruitment of roach (Rutilus rutilus) in the Rhone River (France) between 1987 and 1997.

TL;DR: In this article, the minimum flow at Pierre-Benite, a reach of the Rhone river bypassed by artificial channels, was increased from 10 to 100m3/s−1 in August 2000 (natural mean discharge 1030m/m3−1), resulting in a fivefold increase in average velocity at minimum flow, and principal components analysis revealed a significant change in the relative abundance of fish species.
