Waterfowl disperse weeds and alien plants in crops and wetlands, study finds

The study led by the CSIC confirms that greylag geese spread several plant species between different habitats 300 kilometres from their origin.
Scientists have analyzed faecal samples and the movements of this species marked with GPS for the research carried out in Sweden.

Las especies exóticas presentan una ventaja competitiva durante la dispersión de semillas que realizan las aves acuáticas por endozoocoria

This new study underlines the important role of seed traits in the endozoochory potential of alien and native plant species, notably through their influence on retention time and germination.

Bird migration limits the adaptation of European plants to climate change

A study with the participation of the Doñana Biological Station (CSIC) shows that most of the plants in Europe are dispersed by birds that migrate to warmer areas in autumn. Common birds that winter in Europe and North Africa distribute more seeds to cold latitudes which can be the key to move plant species and adapt to global warming

Seed dispersal by neotropical waterfowl depends on bird species and seasonality

Waterbirds have an important ecological function as vectors of plant dispersal between different wetlands. In the Neotropical region, there is very limited information about this dispersal. In southern Brazil, seed dispersal by endozoochory was studied by five waterfowl, including Brazilian teal, yellow-billed teal, ringed teal, coscoroba swan, and whitefaced whistling-duck. Over 2000 diaspores were recovered from 40 different plants, including seeds of 37 angiosperms, and diaspores of...

Defaunation precipitates the extinction of evolutionarily distinct interactions in the Anthropocene

Species on Earth are interconnected with each other through ecological interactions. Defaunation can erode those connections, yet we lack evolutionary predictions about the consequences of losing interactions in human-modified ecosystems. Here, the fate of the evolutionary history of avian–seed dispersal interactions across tropical forest fragments is quantified.
