A new conceptual and methodological framework for exploring and explaining pattern in presence – absence data
A conceptual framework is proposed to evaluate the relative importance of beta diversity, nestedness and agreement in species richness in presence – absence data matrices via partitioning pairwise gamma diversity into additive components using a two-dimensional simplex diagram, or ternary plot.

Network thinking in riverscape conservation – A graph-based approach
It is demonstrated how a network-based context can be used for enhancing the more effective conservation of riverine systems and suggested that network analyses offer a simple, yet effective tool for searching for key segments in riverscapes for conservation and environmental management. Expand
On dendrogram-based measures of functional diversity
Euclidean distance is commonly involved in calculating functional diversity (FD), for example, in measures based on dendrogram branch lengths. We point out that this function is inappropriate in manyExpand
A comparative analysis reveals weak relationships between ecological factors and beta diversity of stream insect metacommunities at two spatial levels
The hypotheses that beta diversity should increase with decreasing latitude and increase with spatial extent of a region have rarely been tested based on a comparative analysis of multiple datasets,Expand
Characterizing connectivity relationships in freshwaters using patch-based graphs
It is argued that the application of graphs can be a useful tool for quantifying habitat connectivity of freshwater ecosystems and a conceptual framework for the topological analysis of stream networks from a hierarchical patch-based context is presented. Expand
A general framework for analyzing beta diversity, nestedness and related community-level phenomena based on abundance data
A procedure for evaluating the relative importance of beta diversity, nestedness, and similarity properties of ecological data matrices containing density, cover or biomass scores of species by extension of the simplex approach to abundances. Expand
Functional diversity: a review of methodology and current knowledge in freshwater macroinvertebrate research
The review of current methodology for assessing functional diversity in freshwater macroinvertebrate research showed that most papers quantified functional diversity using biological traits, among which feeding habits were the most common traits probably due to the assumed links between feeding and ecosystem functions. Expand
A macroecological perspective of trait patterns in stream communities
The question of how the trait composition of stream communities varies along geographical and environmental gradients is far from settled and the methodology should be carefully considered in comparisons among studies, because contrasting results may reflect not only ecological differences but also differences in methodology.

Importance of visual and chemical cues in the development of an attractant trap for Epicometis (Tropinota) hirta Poda (Coleoptera: Scarabaeidae)
The sex ratio did not differ in traps with only visual or chemical cues, or with both cues together, and reflected the natural sex ratio of the local population, which showed a decrease in male to female ratio as the season progressed. Expand
Partitioning taxon, phylogenetic and functional beta diversity into replacement and richness difference components
The empirical examples show that comparing Pβ and Fβ with the most commonly used Tβ revealed previously hidden patterns of beta diversity, and the methods presented here provide a tool for effectively disentangling the replacement and richness difference components of the different biodiversity facets within the same methodological framework.
