TL;DR: In this paper, the authors examined the concept of a periodic table of niches and feasibility of niche classification schemes from functional trait and performance data, and compared two approaches for producing niche schemes: species ordination within niche gradient space, and niche categorisation according to trait-value thresholds.

TL;DR: In this article, the authors summarize observed and expected impacts of hydroelectric dams on tropical fishes and fisheries through the lens of fish functional traits and consequences of shifting functional diversity for social-ecological systems.

TL;DR: Analysis of seasonal changes in functional trait distributions of tropical fishes in the Xingu River, a major tributary of the Amazon with large predictable temporal variation in hydrologic conditions and species density, demonstrates that the relative influence of community assembly mechanisms can vary seasonally in response to changing abiotic conditions and suggests that studies attempting to infer a single dominant mechanism from functional patterns may overlook important aspects of the assembly process.

TL;DR: In this article, the authors surveyed fish assemblages within rapids in the three segments impacted by the BMHC prior to hydrologic alteration, and tested for differences in assemblage structure between segments and seasons.
