Subterranean Life-Style Does Not Limit Long Distance Dispersal in African Mole-Rats

open access: yesFrontiers in Ecology and Evolution, 2022
Dispersal from the natal site to breeding sites is a crucial phase in the life history of animals and can have profound effects on the reproductive ecology and the structure of animal societies.

Long-distance dispersal in amphibians [PDF]

open access: yesFrontiers of Biogeography, 2019
Although the distribution patterns of major amphibian lineages are mainly explained by a Pangean origin with subsequent vicariant diversification, dispersal events have exerted a strong influence on present-day distributions. Long-distance dispersal (LDD) involves movements outside the standard geographic limits and outside the genetic neighbourhood ...

Distance decay of similarity in neotropical diatom communities. [PDF]

open access: yesPLoS ONE, 2012
BackgroundThe regression of similarity against distance unites several ecological phenomena, and thus provides a highly useful approach for illustrating the spatial turnover across sites.

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

Exaggerated Death of Distance: Revisiting Distance Effects on Regional Price Dispersions [PDF]

open access: yesSSRN Electronic Journal, 2010
Past studies in the literature of the law of one price (LOP) show statistically significant but economically subtle roles of geographical distance in regional price dispersions. In this paper, we challenge this empirical “death of distance” as a primary source of LOP violations investigating a unique daily data set of wholesale prices of agricultural ...

Density-dependent natal dispersal patterns in a leopard population recovering from over-harvest. [PDF]

open access: yesPLoS ONE, 2015
Natal dispersal enables population connectivity, gene flow and metapopulation dynamics. In polygynous mammals, dispersal is typically male-biased. Classically, the 'mate competition', 'resource competition' and 'resident fitness' hypotheses predict ...

Movement, Dispersion, and Orientation of a Population of the Colorado Potato Beetle, \u3ci\u3eLeptinotarsa Decemlineata\u3c/i\u3e (Coleoptera: Chrysomelidae), in Eggplant [PDF]

open access: yes, 2017
Short-term dispersal, dispersion, and orientation of a population of the Colorado potato beetle, Leptinotarsa decemlineata. were examined in a uniformly spaced planting of eggplant using a mark-recapture technique.

Predation risk increases dispersal distance in prey [PDF]

open access: yesNaturwissenschaften, 2014
Understanding the ecological factors that affect dispersal distances allows us to predict the consequences of dispersal. Although predator avoidance is an important cause of prey dispersal, its effects on dispersal distance have not been investigated.

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

open access: yes, 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

Dispersal traits may reflect dispersal distances, but dispersers may not connect populations demographically [PDF]

open access: yesOecologia, 2017
Ecological traits that reflect movement potential are often used as proxies for measured dispersal distances. Whether such traits reflect actual dispersal is often untested. Such tests are important because maximum dispersal distances may not be achieved and many dispersal events may be unsuccessful (without reproduction).
