Competition for Dispersal in Ant-Dispersed Plants

Science, 1981
Two closely related and coexisting plants (Chenopodiaceae) of the Australian arid zone are adapted for seed dispersal by ants. These facultatively perennial shrubs persist in saltbush communities largely as a result of highly directional dispersal to ant mounds, where conditions are favorable for establishment and growth.

Dispersal in Plants

2008
AbstractEcologists, both practical and theoretical, now appreciate that to understand biological systems they must consider the spatial dimension. Consequently, dispersal has become one of the hottest topics in plant ecology. However, in the midst of so much research output on dispersal, there is a need for a stock-take to determine the needs of future

Pollen and seed dispersal among dispersed plants

Biological Reviews, 2005
ABSTRACTThe ecological significance of spacing among plants in contributing to the maintenance of species richness, particularly in tropical forests, has received considerable attention that has largely focussed on distance ‐ and density‐dependent seed and seedling mortality.

Stochastic Dispersal Processes in Plant Populations

Theoretical Population Biology, 1997
A dispersal model for airborne pollen based on assumptions about wind directionality, gravity, and a wind threshold at which pollen is taken by the wind is developed, using a three dimensional diffusion approximation. The bivariate probability distribution of pollen receipt by flowers at the same height as the pollen source is derived.

Seed dispersal interactions promoting plant invasions.

2020
Abstract Animal dispersers are essential for many non-native plants since they facilitate seed movement and might promote seed germination and seedling establishment, thereby increasing their chances of invasion. This chapter reviews the published literature on seed dispersal of non-native plant species by native and/or non-native animals.

Long-Distance Dispersal of Plants

Science, 2006
Long-distance dispersal (LDD) of plants poses challenges to research because it involves rare events driven by complex and highly stochastic processes. The current surge of renewed interest in LDD, motivated by growing recognition of its critical importance for natural populations and communities and for humanity, promises an improved, quantitatively ...

Seed consumption and dispersal of ant-dispersed plants by slugs

Oecologia, 2010
In beech-dominated forests in Central Europe, many spring geophytes show adaptations to seed dispersal by ants (myrmecochory). Ants, however, can be rare in such moist forests. Motivated by observations of slug feeding on seeds we investigated the seed consumption of two plant species, Anemone nemorosa and Asarum europaeum, by slugs, in a series of ...

Passive directed dispersal of plants by animals

Biological Reviews, 2022
ABSTRACTConceptual gaps and imprecise terms and definitions may obscure the breadth of plant–animal dispersal relationships involved in directed dispersal. The term ‘directed’ indicates predictable delivery to favourable microsites. However, directed dispersal was initially considered uncommon in diffuse mutualisms (i.e.

Dispersal of Plants in Fragmented Landscapes

1996
The decline of plant species and populations during the last decades is obvious in the man-made landscape in Central Europe (Korneck & Sukopp 1988). Although many nature reserves were established, the decline is going on. The most obvious reasons outside nature reserves are change of land use, drainage, and pollution by nutrients.
