Woodpeckers can act as dispersal vectors for fungi, plants, and microorganisms

open access: yesEcology and Evolution, 2021
Bird‐mediated dispersal is presumed to be important in the dissemination of many different types of organisms, but concrete evidence remains scarce. This is especially true for biota producing microscopic propagules.

An equation-free computational approach for extracting population-level behavior from individual-based models of biological dispersal [PDF]

open access: yes, 2005
The movement of many organisms can be described as a random walk at either or both the individual and population level. The rules for this random walk are based on complex biological processes and it may be difficult to develop a tractable ...

Alien insect dispersal mediated by the global movement of commodities

open access: yesEcological Applications, 2022
Globalization and economic growth are recognized as key drivers of biological invasions. Alien species have become a feature of almost every biological community worldwide, and rates of new introductions continue to rise as the movement of people and ...

Secondary wind dispersal enhances long-distance dispersal of an invasive species in urban road corridors [PDF]

open access: yes, 2011
Roads contribute to habitat fragmentation and function as dispersal barriers for many organisms. At the same time many nonnative plant species are associated with road systems, a relationship that has been explained by the availability of disturbed ...

Effective long-distance pollen dispersal in Centaurea jacea [PDF]

open access: yes, 2009
BACKGROUND: Agri-environment schemes play an increasingly important role for the conservation of rare plants in intensively managed agricultural landscapes.

Dispersal Kernel Type Highly Influences Projected Relationships for Plant Disease Epidemic Severity When Outbreak and At-Risk Populations Differ in Susceptibility

open access: yesLife, 2022
In silico study of biologically invading organisms provide a means to evaluate the complex and potentially cryptic factors that can influence invasion success in scenarios where empirical studies would be difficult, if not impossible, to conduct.

The constant philopater hypothesis : a new life history invariant for dispersal evolution [PDF]

open access: yes, 2015
This research was supported by Wolfson College Cambridge (A.M.M.R.) and the Natural Environment Research Council (grant no. NE/K009524/1) (A.G.).Surprising invariance relationships have emerged from the study of social interaction, whereby a cancelling ...

Refuge distributions and landscape connectivity affect host-parasitoid dynamics: Motivations for biological control in agroecosystems

open access: yesPLoS ONE, 2022
Species distributions are affected by landscape structure at different spatial scales. Here we study how the interplay between dispersal at different spatial scales and landscape connectivity and composition affect local species dynamics.

A method to quantify jump dispersal of invasive species from occurrence data: the case of the spotted lanternfly, Lycorma delicatula [PDF]

open access: yesNeoBiota
The accuracy of predicting the spread of biological invasions is improved if models explicitly incorporate the two main dispersal mechanisms: diffusive spread and jump dispersal.

Rapid evolution of dispersal ability makes biological invasions faster and more variable

open access: yesNature Communications, 2017
Genetic variation in dispersal ability may result in the spatial sorting of alleles during range expansion. Recent theory suggests that spatial sorting can favour the rapid evolution of life history traits at expanding fronts, and therefore modify the ...
