Abstract: ABSTRACT. The zooplankton community presents stochastic temporal fluctuation and heterogeneous spatial variation determined by the relationships among the organisms and environmental conditions. We predicted that the temporal and spatial zooplankton distribution is heterogeneous and discrete, respectively, and that the daily variation of most abundant species is related to environmental conditions, specifically the availability of resources. Zooplankton samples were collected daily at three sampling stations i… Show more

“…These situations could be attributed to the eutrophic conditions, which dominated in the area of study most of the year. The temporal variation of evenness may be due to the predominance of some species in different times, the effect of food availability, and biotic relationships among the species (Takahashi et al 2014). Although the area of the present study could be considered as stressed area, the dominance index was low, and showed significant positive correlation with salinity and significant negative correlation with chlorophyll.…”

“…No caso dos eucariotos, uma das classificações que vem sendo bem aceita, foi proposta inicialmente por Baldauf, em 2003, modificada posteriormente por ela em conjunto com outros pesquisadores em 2007 (LOPES; CHOW HO, 2016). Conforme Baldauf (2008) e Lopes e Chow Ho (2016) e Takahashi et al (2014), os protozoários de vida livre estão distribuídos nos grupos: Amebozoa, Rhizaria, Alveolados e Excavados Amitocondriados.…”

“…Dentro de los factores ambientales que estacionalmente influyen en la estructura de las comunidades zooplanctónicas se encuentran la temperatura, salinidad, oxígeno disuelto, flujo de agua dulce y estratificación, así como por factores biológicos, entre los que se incluyen, limitación de alimento, depredación y competencia, o por la combinación de ambos tipos de factores (David et al 2005, Takahashi et al 2014. Asimismo, muchas especies del zooplancton pueden variar sus profundidades de residencia, durante diferentes estadios de desarrollo, presentando migraciones ontogénicas, proceso en el cual a medida que las especies mudan y pasan de un estadio a otro, cambian su profundidad de residencia.…”

“…Aunque las variaciones a escalas cortas de tiempo han sido principalmente documentadas para la comunidad del fitoplancton (Hall et al 2015, Sin et al 2015, se han observado cambios nictímeros en la composición y abundancia del zooplancton (Marques et al 2009, Muciño-Márquez et al 2011, Chew et al 2015, los cuales se relacionan con condiciones de luz favorables, evasión de la depredación, disponibilidad de alimento y reproducción (Takahashi et al 2014, Leach et al 2015, Epifanio & Cohen 2016, lo que provoca movimientos verticales que ocurren con una frecuencia diaria (migraciones 'diurno-nocturnas'), siendo el caso normal ascender al anochecer y descender al amanecer (Williamson et al 2011, Chew et al 2015, Vineetha et al 2015.…”
