Phyllotaxis: is the golden angle optimal for light capture?

New Phytologist, Volume 225, Issue 1, Page 499-510, January 2020., 2020
Summary Phyllotactic patterns are some of the most conspicuous in nature. To create these patterns plants must control the divergence angle between the appearance of successive organs, sometimes to within a fraction of a degree. The most common angle is the Fibonacci or golden angle, and its prevalence has led to the hypothesis that it has been ...

Vriesea (Bromeliaceae, Tillandsioideae): a cladistic analysis of eastern Brazilian species based on morphological characters

Rodriguésia
Vriesea, with about 280 species distributed in two sections, Vriesea and Xiphion, is recognized as polyphyletic. We provide the cladistic analysis based on morphological data, with emphasis on species from eastern Brazil, its main center of diversity ...

Effect of rosette size, clonality and spatial distribution on the reproduction of Vriesea carinata (Bromeliaceae) in the Atlantic Forest of Paraná, southern Brazil

Acta Botânica Brasílica, 2016
Plant size and clonality are important traits for explaining the reproductive effort of clonal plants. Larger plants can invest more resources into reproduction, and clonality is known to increase reproductive effort.

Inconsistent effects of P enrichment and predator presence on food‐web dynamics in a bromeliad system

Oikos, Volume 2026, Issue 3, March 2026.
Food webs consist of trophic interactions of variable strength. However, it remains challenging to predict how changes in environmental conditions, such as nutrient enrichment, can affect these interactions. In this paper, we propose to integrate food web theory with ecological stoichiometry, which predicts how elemental ratios affect trophic ...
