Dispersal of larval and juvenile seabream: Implications for Mediterranean marine protected areas [PDF]

open access: yes, 2015
In the marine context, information about dispersal is essential for the design of networks of marine protected areas (MPAs). Generally, most of the dispersal of demersal fishes is thought to be driven by the transport of eggs and larvae in currents, with

Approaches to Dispersing Medical Biofilms

open access: yesMicroorganisms, 2017
Biofilm-associated infections pose a complex problem to the medical community, in that residence within the protection of a biofilm affords pathogens greatly increased tolerances to antibiotics and antimicrobials, as well as protection from the host ...

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

open access: yes, 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

Aproceros leucopoda (Hymenoptera: Argidae): An East Asian pest of elms (Ulmus spp.) invading Europe

open access: yesEuropean Journal of Entomology, 2010
An invasive sawfly Aproceros leucopoda Takeuchi, 1939, which originates from East Asia, has colonized elms (Ulmus spp.) in Austria, Hungary, Poland, Romania, Slovakia and the Ukraine, at least since 2003.

After the games are over: life-history trade-offs drive dispersal attenuation following range expansion. [PDF]

open access: yes, 2016
Increased dispersal propensity often evolves on expanding range edges due to the Olympic Village effect, which involves the fastest and fittest finding themselves together in the same place at the same time, mating, and giving rise to like individuals ...

Anthropogenic seed dispersal: rethinking the origins of plant domestication

open access: yes, 2020
It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as

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

open access: yes, 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

Genetics of dispersal [PDF]

open access: yesBiological Reviews, 2017
ABSTRACTDispersal is a process of central importance for the ecological and evolutionary dynamics of populations and communities, because of its diverse consequences for gene flow and demography. It is subject to evolutionary change, which begs the question, what is the genetic basis of this potentially complex trait?

Long-Distance Wind-Dispersal of Spores in a Fungal Plant Pathogen: Estimation of Anisotropic Dispersal Kernels from an Extensive Field Experiment [PDF]

open access: yes, 2014
Given its biological significance, determining the dispersal kernel (i.e., the distribution of dispersal distances) of spore-producing pathogens is essential. Here, we report two field experiments designed to measure disease gradients caused by sexually-

Plant dispersal across the tropical Atlantic by wind and sea currents [PDF]

open access: yes, 2004
This review brings together evidence on the monophyly and ages of angiosperm lineages ranging across the tropical Atlantic with data on the direction, strength, and speed of sea currents and wind jets across that ocean. Mainly for pragmatic reasons (data
