Patterns of /r/ variation

Global variation in elevational diversity patterns.

While horizontal gradients of biodiversity have been examined extensively in the past, vertical diversity gradients (elevation, water depth) are attracting increasing attention. We compiled data from 443 elevational gradients involving diverse organisms worldwide to investigate how elevational diversity patterns may vary between the Northern and Southern hemispheres and across latitudes. Our re...

Phenotypic variation explains food web structural patterns.

Food webs (i.e., networks of species and their feeding interactions) share multiple structural features across ecosystems. The factors explaining such similarities are still debated, and the role played by most organismal traits and their intraspecific variation is unknown. Here, we assess how variation in traits controlling predator-prey interactions (e.g., body size) affects food web structur...

Variation and consistency in children’s truncation patterns

Children’s truncations of multisyllabic words, i.e. the omission of entire syllables, are investigated. More specifically, the consistency of truncation patterns is analyzed in two studies. First, a systematic quantitative analysis of the truncations of a single Dutch speaking Flemish boy is reported. Secondly, the generalizability of the findings of the case study is assessed: the results are ...

Variation of pitch accent patterns in Hungarian

In Hungarian, focussed elements occur in certain syntactic positions. Because of this limitation, prominence marking by means of prosody is less salient than in languages where focus can be expressed by accent shift without changes in word order. In this study, we examined Hungarian utterances that were identical in their segmental structure, but differed with regard to their semantic and pragm...
