Human impact, climate and dispersal strategies determine plant invasion on islands
Journal of Biogeography, 2021 Biological invasions are likely determined by species dispersal strategies as well as environmental characteristics of a recipient region, especially climate and human impact.

Evolution of dispersal and the ideal free distribution
Mathematical Biosciences and Engineering, 2009 A general question in the study of the evolution of dispersalis what kind of dispersal strategies can conveycompetitive advantages and thus will evolve.We consider a two species competition modelin which the species are assumed to have the same ...

Sex‐biased dispersal: a review of the theory [PDF]
Biological Reviews of The Cambridge Philosophical Society, 2018 Dispersal is ubiquitous throughout the tree of life: factors selecting for dispersal include kin competition, inbreeding avoidance and spatiotemporal variation in resources or habitat suitability.

Theory of ac electrokinetic behavior of spheroidal cell suspensions with an intrinsic dispersion [PDF]
Phys. Rev. E 67, 021910 (2003), 2002 The dielectric dispersion, dielectrophoretic (DEP) and electrorotational (ER) spectra of spheroidal biological cell suspensions with an intrinsic dispersion in the constituent dielectric constants are investigated. By means of the spectral representation method, we express analytically the characteristic frequencies and dispersion strengths both for ...

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 ...

Effect of dispersants on bacterial colonization of oil droplets: a microfluidic approach [PDF]
, 2022 Bacteria biodegradation of immiscible oil requires cell-droplet encounters, surface attachment, and hydrocarbon metabolism. Chemical dispersants are applied to oil spills to reduce the mean dispersed droplet size, thereby increasing the available surface area for attachment, in attempts to facilitate bacterial biodegradation.

Biological Invasions, 2018 Dispersal abilities of invading species emerge from the interaction between the species and some features of the target community. Ligustrum lucidum is a tree species invading different ecosystems.

Evolution of unconditional dispersal in periodic environments [PDF]
Journal of Biological Dynamics (special issue on Adaptive
Dynamics). Vol. 5, pp. 120-134 (2011), 2010 Organisms modulate their fitness in heterogeneous environments by dispersing. Prior work shows that there is selection against "unconditional" dispersal in spatially heterogeneous environments. "Unconditional" means individuals disperse at a rate independent of their location.
