High potential of sub-Mediterranean dry grasslands for sheep epizoochory

Open Life Sciences, 2016
There is a general decline of grasslands across Europe due to habitat loss and degradation. Ensuring plant dispersal thus becomes a key process for preserving grassland patches in all scales.

RETRACTED ARTICLE: The role of seed appendage in improving the adaptation of a species in definite seasons: a case study of Atriplex centralasiatica

BMC Plant Biology, 2019
Background As a common accompanying dispersal structure, specialized seed appendages play a critical role in the successful germination and dispersal of many plants, and are regarded as an adaptation character for plants survival in diverse environments.

Effects of seed morphology and elaiosome chemical composition on attractiveness of five Trillium species to seed‐dispersing ants

Ecology and Evolution, 2020
Morphological and chemical attributes of diaspores in myrmecochorous plants have been shown to affect seed dispersal by ants, but the relative importance of these attributes in determining seed attractiveness and dispersal success is poorly understood ...

Plant traits co-vary with altitude in grasslands and forests in the European Alps [PDF]

, 2018
Biological traits that are advantageous under specific ecological conditions should be present in a large proportion of the species within an ecosystem, where those specific conditions prevail.
