Opportunistic suspension feeding in the intertidal gastropod Olivella columellaris and its implications for the regulation of tidal migrations
The gastropod Olivella columellaris inhabits sandy beaches of the Tropical East Pacific. These snails perform tidal migrations forcontinuous suspension feeding in the moving backwash zone, possibly controlled by an endogenous circatidal clock. However, O. columellaris readily modifies its circatidal...

El gasterópodo Olivella columellaris habita las playas arenosas del Pacífico Oriental Tropical. Estos caracoles suelen realizar migraciones mareales ya que se alimentan de partículas en suspensión en la zona de resaca que se mueve con la marea. Aunque este comportamiento posiblemente esté regulado por un reloj endógeno que sigue los ritmos mareales, O. columellaris fácilmente puede modificarlo. Por ejemplo, cuando se crean pequeños canales que drenan el agua de las pozas (naturales o artificiales) generadas en marea baja, la alimentación suspensívora continúa mientras el agua esté corriendo, retrasándose así la migración mareal. Dicha plasticidad en el comportamiento cuestiona la importancia de los ritmos endógenos en la regulación de las migraciones mareales de O. columellaris. 2016-12-20 2021-06-03T03:55:31Z 2021-06-03T03:55:31Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2640 10.7773/cm.v42i4.2640 https://hdl.handle.net/20.500.12930/7506 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2640/1612 Copyright (c) 2016 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 42 No. 4 (2016); 289–294 Ciencias Marinas; Vol. 42 Núm. 4 (2016); 289–294 2395-9053 0185-3880 |
