Understanding the relationship between dispersal and range size

open access: yesEcology Letters, Volume 25, Issue 10, Page 2303-2323, October 2022., 2022
Dispersal is one of the most prominent hypothesised predictors of range size, but the theoretical expectation of a positive dispersal‐range size relationship has received mixed empirical support. By synthesising results from 86 studies on plants and animals in marine, terrestrial and freshwater realms, we show that the overall effect of dispersal on ...

Increasing abundance of an invasive C4 grass is associated with larger community changes away than at home

open access: yesApplied Vegetation Science, Volume 25, Issue 2, Page 1-11, April/June 2022., 2022
We evaluated the functional characteristics of plant communities along the abundance gradient of Sporobolus cryptandrus, a C4 bunchgrass, in its both native North American and recent non‐native European ranges. We found that Sporobolus invasion in Europe leads to impoverishment of the host communities and compromises the biomass and floral resource ...

A roadmap to plant functional island biogeography

open access: yesBiological Reviews, Volume 96, Issue 6, Page 2851-2870, December 2021., 2021
ABSTRACT Island biogeography is the study of the spatio‐temporal distribution of species, communities, assemblages or ecosystems on islands and other isolated habitats. Island diversity is structured by five classes of process: dispersal, establishment, biotic interactions, extinction and evolution.

“Step by step”: high frequency short-distance epizoochorous dispersal of aquatic macrophytes [PDF]

open access: yes, 2016
Aquatic macrophytes can successfully colonise and re-colonise areas separated by space and time. The mechanisms underlying such “mobility” are not well understood, but it has often been hypothesised that epizoochory (external dispersal) plays an ...

The recent and rapid spread of Themeda triandra [PDF]

open access: yes, 2017
Tropical savannas cover over 20% of land surface. They sustain a high diversity of mammalian herbivores and promote frequent fires, both of which are dependent on the underlying grass composition.

First record of Echinogammarus pungens (H. Milne Edwards, 1840) (Crustacea, Amphipoda) from Africa with the checklist of North African freshwater gammarids [PDF]

open access: yes, 2014
Taking into account the vast area of North Africa, the freshwater gammarid fauna of this area remains rather poorly studied. So far, 20 species of the three following genera: Echinogammarus (11 species), Gammarus (8 spp.) and Chaetogammarus (1 sp.) have ...

Morphological characterization of fruits and seeds of Ruellia furcata (Nees) Lindau (Acanthaceae) from Espírito Santo State, Brazil [PDF]

open access: yes, 2020
Acanthaceae is a wide spread family with usually capsular fruits, with two valves and explosive dehiscence containing two or more seeds. The morphological features of fruits and seeds are important in the identification at supra especific level, since ...

Diversity and dynamics of hydrophilic flora of Lowland Polissya (on the example of the Sluch River basin) [PDF]

open access: yes, 2021
Study and analysis of hydrophilic flora diversity are important parts of environmental research due to various functions of vascular macrophytes in freshwater ecosystems, which deteriorate under the influence of anthropogenic activity and climate change.

The importance of waterbirds as an overlooked pathway of invasion for alien species [PDF]

open access: yes, 2015
The importance of waterbirds as vectors of aliens has been recognized since Darwin's time, yet research by pioneers has been forgotten during the development of modern invasion biology, which tends to overlook this means of dispersal.
