Deriving dispersal distances from genetic data [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2001
Dispersal is one of the most important factors determining the genetic structure of a population, but good data on dispersal distances are rare because it is difficult to observe a large sample of dispersal events. However, genetic data contain unbiased information about the average dispersal distances in species with a strong sex bias in their ...

Patterns, causes, and consequences of marine larval dispersal [PDF]

, 2015
Quantifying the probability of larval exchange among marine populations is key to predicting local population dynamics and optimizing networks of marine protected areas. The pattern of connectivity among populations can be described by the measurement of

Seed dispersal in six species of terrestrial orchids in Biebrza National Park (NE Poland)

Acta Societatis Botanicorum Poloniae, 2017
Knowledge about seed dispersal is required to explain problems in ecology, phylogeography, and conservation biology. Even though seed dispersal is a fundamental mechanism to understand problems at different levels of biological organization (individual ...

Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]

, 2012
Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

Rapid, Long-Distance Dispersal by Pumice Rafting [PDF]

PLoS ONE, 2012
Pumice is an extremely effective rafting agent that can dramatically increase the dispersal range of a variety of marine organisms and connect isolated shallow marine and coastal ecosystems. Here we report on a significant recent pumice rafting and long-distance dispersal event that occurred across the southwest Pacific following the 2006 explosive ...

Long-Distance Pollen Dispersal in Urban Green Roof and Ground-Level Habitats

Frontiers in Ecology and Evolution, 2022
Long-distance pollen dispersal is critical for gene flow in plant populations, yet pollen dispersal patterns in urban habitats such as green roofs have not been extensively studied.

Long-Distance Dispersal of Fungi

Microbiology Spectrum, 2017
ABSTRACTDispersal is a fundamental biological process, operating at multiple temporal and spatial scales. Despite an increasing understanding of fungal biodiversity, most research on fungal dispersal focuses on only a small fraction of species. Thus, any discussion of the dispersal dynamics of fungi as a whole is problematic.

Evolution of the distribution of dispersal distance under distance-dependent cost of dispersal [PDF]

Journal of Evolutionary Biology, 2002
Abstract We analyse the evolution of the distribution of dispersal distances in a stable and homogeneous environment in one- and two-dimensional habitats. In this model, dispersal evolves to avoid the competition between relatives although some cost might be associated with this behaviour. The evolutionarily stable dispersal distribution

Individual Nest Site Preferences Do Not Explain Upslope Population Shifts of a Secondary Cavity-Nesting Species

Animals, 2021
Geographic ranges of plants and animals are shifting due to environmental change. While some species are shifting towards the poles and upslope in elevation, the processes leading to these patterns are not well known.

Foray search: An effective systematic dispersal strategy in fragmented landscapes [PDF]

, 2003
In the absence of evidence to the contrary, population models generally assume that the dispersal trajectories of animals are random, but systematic dispersal could be more efficient at detecting new habitat and may therefore constitute a more realistic ...
