{"volume":48,"abstract":[{"lang":"eng","text":"The dispersal rate of the grasshopper Podisma pedestris has been measured, with the aim of interpreting the width of a chromosomal cline. 171 adults were marked individually, and released within the cline. 169 movements were seen over three subsequent scorings; the distribution of distances, after correction for the loss of long distance dispersants, was close to a normal curve, but there was an initial shift of ten metres, perhaps towards a better habitat. The linear variance increased at about 214 m2 day- 1, which corresponds to a standard deviation of 207 m gen- 1/2 over a 20 day life span. Statistical uncertainty in this estimate can be expressed using a distribution-free maximum likelihood method, which gives support limits of 186- 270 m gen- 1/2. However, the main errors come from extrapolating from this experiment to the cline as a whole."}],"publication_status":"published","status":"public","author":[{"orcid":"0000-0002-8548-5240","first_name":"Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","full_name":"Barton, Nicholas H","last_name":"Barton"},{"last_name":"Hewitt","full_name":"Hewitt, Godfrey","first_name":"Godfrey"}],"page":"237 - 249","article_type":"original","publist_id":"2714","year":"1982","language":[{"iso":"eng"}],"extern":"1","main_file_link":[{"url":"https://www.nature.com/articles/hdy198229","open_access":"1"}],"citation":{"chicago":"Barton, Nicholas H, and Godfrey Hewitt. “A Measurement of Dispersal in the Grasshopper Podisma Pedestris (Orthoptera: Acrididae).” <i>Heredity</i>.
