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 derived understanding of LDD. To gain deep insights into the patterns, mechanisms, causes, and consequences of LDD, we must look beyond the… Expand
Mechanisms of long-distance seed dispersal.
TLDR
To advance the understanding of LDD, this work advocates a vector-based research approach that identifies the significant LDD vectors and quantifies how environmental conditions modify their actions. Expand
Long-distance dispersal: a framework for hypothesis testing.
TLDR
Data for terrestrial (including littoral) organisms in the Pacific is examined to show that knowledge of dispersal by wind, birds and oceanic drift or rafting, coupled with information about the natural environment and biology of the organisms, can be used to generate broad biogeographic predictions. Expand
Non-random seed abscission, long-distance wind dispersal and plant migration rates
TLDR
This study shows how the small-scale process of a seed being released from the plant could affect the large-scale spatial dynamics of plant species in landscapes. Expand
Space, time and complexity in plant dispersal ecology
TLDR
It is argued here that advances in plant dispersal ecology research will be determined by the ability to surmount challenges of spatiotemporal scales and heterogeneities and ecosystem complexity. Expand
Long distance dispersal in the assembly of floras: A review of progress and prospects in North America
Here, we review progress and prospects to explicitly test for long distance dispersal biogeographic events. Long distance dispersal represents a “jump” across some kind of barrier, such as aExpand
Long‐distance natal dispersal is relatively frequent and correlated with environmental factors in a widespread raptor
TLDR
Findings that L DD occurs at a relatively high frequency and is related to different proximate factors from SDD, including a lack of sex‐bias in LDD, suggest that LDD may be more common than previously reported, and LDD and SDD may be distinct processes rather than two outcomes originating from a single dispersal distribution. Expand
Explaining long-distance dispersal: effects of dispersal distance on survival and growth in a stream salamander.
TLDR
The results suggest that consistent evolutionary mechanisms may explain the prevalence of LDD in nature and highlight the value of direct CMR data for understanding the individual consequences of variation in dispersal distance and how that variation is maintained in natural populations. Expand
The geography of human-mediated dispersal
Abstract Dispersal is a key process in determining the survival of plant species following habitat fragmentation and climate change, as well as driving the introduction and spread of invasiveExpand
Human-mediated dispersal of seeds over long distances
TLDR
It is suggested that walking humans can disperse seeds to very long distances, up to at least 10 km, and some of the first quantified dispersal kernels for HMD are provided. Expand
Long-distance plant dispersal to North Atlantic islands: colonization routes and founder effect
TLDR
This work is the first to quantify the genetic founder effect on islands in relation to island size, dispersal distance, and plant traits and should bring a final end to the 140-year-long glacial survival-tabula rasa debate among northern biologists. Expand

Long-distance seed dispersal in plant populations.
TLDR
It is argued that genetic methods provide a broadly applicable way to monitor long-distance seed dispersal and, hence, that better data is needed from the tails of seeds that travel long distances. Expand
Mechanisms of long-distance dispersal of seeds by wind
TLDR
Simulations show that uplifting above the forest canopy is necessary and sufficient for LDD, hence, they provide the means to define LDD quantitatively rather than arbitrarily, and seed uplifting probability sets an upper bound on the probability of long-distance colonization. Expand
Theoretical Perspectives on Evolution of Long-Distance Dispersal and the Example of Specialized Pests
TLDR
It is concluded that biotic interactions, and in particular specialized natural enemies, are likely to be one of the most important factors selecting for LDD in many species. Expand
Methods for estimating long-distance dispersal
TLDR
This work critically review the main methods employed in studies of dispersal, in order to facilitate the evaluation of their pertinence to specific aspects of LDD research, and identifies six main methodological groups: biogeographical: Eulerian and Lagrangian movement/redistributiona; short-term and long-term genetic analyses; and modeling.

The Ecology and Evolution of Seed Dispersal: A Theoretical Perspective
▪ Abstract Models of seed dispersal—a key process in plant spatial dynamics—have played a fundamental role in representing dispersal patterns, investigating dispersal processes, elucidating theExpand
ARE LONG‐DISTANCE DISPERSAL EVENTS IN PLANTS USUALLY CAUSED BY NONSTANDARD MEANS OF DISPERSAL?
TLDR
It is concluded that the relationship between morphologically defined dispersal syndrome and long-distance dispersal is poor, and understanding gleaned from the often anecdotal literature on nonstandard and standard means of long distance disperseal is the foundation for both statistical and mechanistic models of long- distance dispersal.

Effective Seed Dispersal Across a Fragmented Landscape
The role of seed dispersal in maintaining genetic connectivity among forest fragments has largely been ignored because gene flow by pollen is expected to predominate. By using genealogicalExpand
The Community-Level Consequences of Seed Dispersal Patterns
TLDR
It is argued that the importance of dispersal cannot be taken for granted, and theoretical and empirical work linking dispersal kernels to the relative abundance, distribution, dispersion, and coexistence of species is evaluated. Expand
Seed dispersal by white-tailed deer: implications for long-distance dispersal, invasion, and migration of plants in eastern North America
TLDR
It is concluded that white-tailed deer represent a significant and previously unappreciated vector of seed dispersal across the North American landscape, probably contributing an important long-distance component to the seed shadows of hundreds of plant species, and providing a mechanism to help explain rapid rates of plant migration.

Long-distance dispersal research: building a network of yellow brick roads
TLDR
The need to develop a network integrating different research approaches (‘yellow brick roads’) to address the great challenge of quantifying, understanding and predicting LDD and its implications is emphasized. Expand
