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

Life, 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.

Two‐scale dispersal estimation for biological invasions via synthetic likelihood [PDF]

Ecography, 2017
Biological invasions reshape environments and affect the ecological and economic welfare of states and communities. Such invasions advance on multiple spatial scales, complicating their control. When modeling stochastic dispersal processes, intractable likelihoods and autocorrelated data complicate parameter estimation.

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

PLoS 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]

NeoBiota
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.

Life-history strategy, resource dispersion and phylogenetic associations shape dispersal of a fig wasp community

Movement Ecology, 2017
Background The combined influence of life-history strategy and resource dispersion on dispersal evolution of a biological community, and by extension, on community assemblage, has received sparse attention.

Body size dependent dispersal influences stability in heterogeneous metacommunities

Scientific Reports, 2021
Body size affects key biological processes across the tree of life, with particular importance for food web dynamics and stability. Traits influencing movement capabilities depend strongly on body size, yet the effects of allometrically-structured ...

Evolution of reproductive life‐history and dispersal traits during the range expansion of a biological control agent

Evolutionary Applications, 2022
Evolutionary theory predicts that the process of range expansion will lead to differences in life‐history and dispersal traits between the core and edge of a population.

The role of individual variation in marine larval dispersal

Frontiers in Marine Science, 2014
The exchange of individuals among patchy habitats plays a central role in spatial ecology and metapopulation dynamics. Dispersal (e.g. short vs. long) is frequently observed to vary non-randomly within populations, indicating that variability among ...

A Review of the Phenotypic Traits Associated with Insect Dispersal Polymorphism, and Experimental Designs for Sorting out Resident and Disperser Phenotypes

Insects, 2020
Dispersal represents a key life-history trait with several implications for the fitness of organisms, population dynamics and resilience, local adaptation, meta-population dynamics, range shifting, and biological invasions.

Dispersal mitigates biologically induced disturbances in heterogeneous metacommunities [PDF]

Ecosphere, 2019
AbstractThe global increase in anthropogenic disturbances has introduced patterns of heterogeneity across many landscapes. Local disturbances are often studied from the perspective of the local habitat patch, where their direct effects on local community composition are more evident.
