dc.description.abstract | El actual trabajo de grado se realizó utilizando 30 muestras piston coretop de sedimentosdistribuidas a lo largo del gradiente batimétrico desde la plataforma (39m) y talud (2469m) delCaribe Colombiano. Se contó un total de 7479 caparazones polycystinos: 2933 espumelaridosy 4646 naselaridos. El dominio generalizado de naselaridos indica condiciones más oceánicasque neríticas y de alta salinidad. Se describieron 15 familias, 93 géneros y 104 morfoespeciesLas familias más abundantes son: PLAGONIIDAE (31%), PYLONIIDAE (21%), SPYRIDAE(11%) y SPONGODISCIDAE (10%), que representan el 55% del total de caparazones. Encuanto a los géneros, los más relevantes son: Tetrapyle (10%), Plagonium (8%), Tholospyris(6), Lophophaena (6%), Octapyle (6%), y Arachnocoralium (6%); representan el 43 % delrecuento total. La asociación típica está integrada por: Tetrapyle octachantha, PlagoniidaeGroup, Tholospyris spp. group, Octapyle stenozoa, Arachnocoralium calvata, Lophophaenahispida, Pterocorys minythorax y Peromelissa phalacra. Los valores de diversidad, equidad ydominancia, señalan una distribución equitativa del número de individuos entre las especies, locual, sumado a los bajos valores de URI determinados, indican condiciones de surgencia débilo de no surgencia. Por todo lo anterior, se planteó que la posible surgencia estacional (depresentarse) es de rango bajo y que el principal aporte de nutrientes a la zona de estudioproviene de los afluentes de la región. | |
dc.description.abstractenglish | The present undergraduate research project was conducted using 30 piston coretop sedimentsamples distributed along the bathimetric gradient from shelf (39m) to slope (2469m) of theColombian Caribbean. A total of 7479 polycystine tests: 2933 spumellarians and 4646nasellarians were counted. The general domain of nasellarians indicates high salinity conditionsand a distal setting. 15 families, 93 genera and 104 species were described. The moreabundant families, which represent the 55% of the total recount, were: PLAGONIIDAE (31%),PYLONIIDAE (21%), SPYRIDAE (11%) and SPONGODISCIDAE (10%). Regarding the genera,Tetrapyle (10%), Plagonium (8%), Tholospyris (6), Lophophaena (6%), Octapyle (6%), andArachnocoralium (6%) were the more abundant, representing the 43% of the total recount. Thetypical association is constituted by Tetrapyle octachantha, Plagoniidae group, Tholospyris spp.group, Octapyle stenozoa, Arachnocoralium calvata, Lophophaena hispida, Pterocorysminythorax and Peromelissa phalacra. The high diversity, equity and dominance values,indicate an equitable distribution of the number of individuals among the species. This, inaddition to the low URI values estimated, reflects none upwelling conditions in the study zone.From these facts it was concluded that the upwelling, if present, might be seasonal and of lowrate. And that the principal source of nutrients in the study zone is the river’s input. ? | |
