Opportunistic suspension feeding in the intertidal gastropod Olivella columellaris and its implications for the regulation of tidal migrations

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...

However, O. columellaris readily modifies its circatidal behavior, for example when flow channels develop below natural and artificial tide pools at ebb tide.

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
