Dispersal distance as a benefit of myrmecochory
Oecologia, 1988Nutrient-enrichment and predator avoidance are generally considered the major benefits of myrmecochory, but this is apparently not so in Australia where some of the greatest known concentrations of myrmecochorus plants occur. Here I demonstrate that distance dispersal is a potential benefit of myrmecochory in the Australian environment.

Dispersal among breeding sites in territorial animals (i.e. breeding dispersal) is driven by numerous selection pressures, including competition and spatiotemporal variation in habitat quality.

. Dispersal distance and burial mode of acorns are two of the most important characteristics in renewal processes of oaks that result from the food hoarding ecology of the Eurasian Jay Garrulus glandarius.

Long-Distance Dispersion of Rust Pathogens
Annual Review of Phytopathology, 1990Migration and dispersal are the two main evolutionary strategies adopted by living organisms to colonize new sites. The migration of birds and mammals in search of new sites and sources of food occurs in an orderly, coordinated way with minimum wastage of progenies.

Distance, Group Dispersion and Opinion Change
Psychological Reports, 1965This study extended previous findings with respect to distance and group dispersion as determinants of opinion change. Change in the direction advocated by a group increased as discrepancy between S's opinion and the group norm increased. Change increased as homogeneity of group opinions increased.

Mechanisms of long-distance seed dispersal
Trends in Ecology & Evolution, 2008Growing recognition of the importance of long-distance dispersal (LDD) of plant seeds for various ecological and evolutionary processes has led to an upsurge of research into the mechanisms underlying LDD. We summarize these findings by formulating six generalizations stating that LDD is generally more common in open terrestrial landscapes, and is ...

Long-Distance Dispersal of Plants
Science, 2006Long-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 ...

Dispersion forces at arbitrary distances
Chemical Physics Letters, 1975The formalism of Boehm and Yaris is used to evaluate explicitly the leading term of the London dispersion force between closed-shell atoms. Instead of using the usual multipole expansion, which breaks down at intermediate internuclear distances, an analytic representation of the Born amplitude together with a general angular momentum analysis is used ...

The Biota of Long-Distance Dispersal. I. Principles of Dispersal and Evolution
The Quarterly Review of Biology, 1966A growing consensus of biologists now favors the effectiveness of long-distance dispersal as a means of populating islands. The observational and experimental bases on which this opinion rests are strong, but additional work is needed. A clear under-standing of long-distance dispersal is essential to an understanding of evolutionary trends on oceanic ...
