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 ...

Similar self-organizing scale-invariant properties characterize early cancer invasion and long range species spread [PDF]

, 2007
Occupancy of new habitats through dispersion is a central process in nature. In particular, long range dispersal is involved in the spread of species and epidemics, although it has not been previously related with cancer invasion, a process that involves

Community-driven dispersal in an individual-based predator-prey model [PDF]

, 2008
We present a spatial, individual-based predator-prey model in which dispersal is dependent on the local community. We determine species suitability to the biotic conditions of their local environment through a time and space varying fitness measure ...

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.

Effects of roads on wildlife in an intensively modified landscape [PDF]

, 2000
This paper examines the ecological impacts arising from road networks and the potential ameliorating effects of roadside habitat in a highly modified landscape. A U.K.

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.

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 ...

Harmonia axyridis: an environmental risk assessment for Northwest Europe [PDF]

, 2008
In this paper, we summarize the international situation with respect to environmental risk assessment for biological control agents. Next, we apply a recently designed, comprehensive risk evaluation method consisting of a stepwise procedure to evaluate ...

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.

Darwin’s wind hypothesis: does it work for plant dispersal in fragmented habitats? [PDF]

, 2009
Using the wind-dispersed plant Mycelis muralis, we examined how landscape fragmentation affects variation in seed traits contributing to dispersal.
