Assessing contributions of deterministic versus stochastic processes to local species assembly: A field experiment with annual plant‐dominated communities in gypsum systems

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...

The Alpine Germination Syndrome Differs Between Temperate and Mediterranean Habitats

open access: yesJournal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
We studied four germination cues across 56 species from Mediterranean and temperate alpine habitats to investigate if germination responses differ in a climatically heterogeneous region. Differences between habitats were only observed in germination responses to cold stratification, although germination requirements were highly species‐specific ...

Paleobiology of the genus Hypericum (Hypericaceae): a survey of the fossil record and its palaeogeographic implications

open access: yesAnales del Jardín Botánico de Madrid, 2012
Genus Hypericum is one of the 100 largest genera in angiosperms with nearly 500 species. Despite its worldwide, nearly cosmopolitan distribution and apparently old age – there are fossil remains of relatives from the Mid Cretaceous - the fossil record of
