Spatial distribution of the sand-dwelling fish Gymnorhamphichthys rondoni in a neotropical terra firme stream

Weakly electric fish constantly emit Electric Organ Discharges (EOD) as means of communication and localization. Water conductivity affects the electrocommunication in these fish by increasing its range when water conductivity is low. Therefore, we investigated the effect of water conductivity on th...

description Weakly electric fish constantly emit Electric Organ Discharges (EOD) as means of communication and localization. Water conductivity affects the electrocommunication in these fish by increasing its range when water conductivity is low. Therefore, we investigated the effect of water conductivity on the choosing resting places by the sand-dwelling fish Gymnorhamphichthys rondoni in a terra firme stream known as Yahuarcaca in Leticia Amazonas. This stream is also a nutrient deficient habitat, therefore we explored in addition if this condition may affect EOD frequency discharge rates at rest in G. rondoni individuals. Through five field trips to the sampling site Y4 within this stream we recorded some physicochemical parameters such as water conductivity, and the distribution of G. rondoni individuals. Also, we recorded the EODs of the two closest individuals found throughout the day and night, including the time leaving and returning to their hiding sites. We found that most of the physicochemical parameters did not change...

La conductividad del agua afecta la electro comunicación en éstos peces incrementando su rango cuando la conductividad es baja. Por esta razón exploramos el efecto que ésta tiene en los sitios de reposo de un pez que se entierra en la arena, Gymnorhamphichthys rondoni, en un arroyo de tierra firme, Yahuarcaca, en Leticia Amazonas. Este arroyo es un hábitat pobre en nutrientes, por lo cual también exploramos si esta condición tiene un efecto en la tasa de descarga de los individuos de G. rondoni en el día y noche. Durante cinco muestreos a un sitio de éste arroyo medimos algunos parámetros físico-químicos como la conductividad del agua y además la ubicación de los individuos de G. rondoni. Adicionalmente, grabamos las DOE de los dos individuos más cercanos durante el día y la noche incluyendo la hora de salida y llegada al sitio de reposo...Magíster en Ciencias BiológicasMaestría28 hojasapplication/pdfengUniversidad de los AndesMaestría en Ciencias BiológicasFacultad de CienciasDepartamento de Ciencias BiológicasSpatial distribution of the sand-dwelling fish Gymnorhamphichthys rondoni in a neotropical terra firme streamTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMGymnorhamphichthys rondoniOrganos eléctricos en los pecesPeces eléctricos20154409Publicationhttps://scholar.google.es/citations?user=nCoNP_MAAAAJvirtual::15471-10000-0003-3018-6726virtual::15471-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001012053virtual::15471-19868e8c9-c2f8-458f-9d29-ed9d658b59fevirtual::15471-19868e8c9-c2f8-458f-9d29-ed9d658b59fevirtual::15471-1ORIGINAL13197.pdfapplication/pdf1051114https://repositorio.uniandes.edu.co/bitstreams/986a5be2-a830-429a-ad2b-8d8073a1cbaf/downloade5f8cfb8acff283e2a3f59058ec50666MD51THUMBNAIL13197.pdf.jpg13197.pdf.jpgIM Thumbnailimage/jpeg21335https://repositorio.uniandes.edu.co/bitstreams/962b616a-a8a1-4391-92b5-4310b21c73ec/download19f2e8f96106f04e1a1133b9b9bad4bdMD53TEXT13197.pdf.txt13197.pdf.txtExtracted texttext/plain47252https://repositorio.uniandes.edu.co/bitstreams/68a8347e-9f6a-4b51-996f-5cbfa8755b51/download049207b4ada7453bac7011121c31c161MD521992/61932oai:repositorio.uniandes.edu.co:1992/619322024-03-13 15:28:17.469http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co
