Trophic-functional patterns of biofilm-dwelling ciliates at different water depths in coastal waters of the Yellow Sea, northern China

Colonization dynamics of periphytic ciliates at different water depths in coastal waters of the Yellow Sea, northern China

“…Our recent reports have demonstrated that the community structure and trophic-functional patterns of periphytic ciliates can be shaped by water depths in spite of the water mixture among different water layers in coastal waters (Abdullah Al et al ., 2017, 2018). Generally, the abundance of microalgae in biofilms are high in surface layers with high light intensity while the periphytic and planktonic bacteria are more abundant in deep layers (Coppellotti & Matarazzo, 2000; Eisenmann et al ., 2001; Norf et al ., 2009 a , 2009 b ; Abdullah Al et al ., 2017, 2018). Abdullah Al et al .…”

“…Furthermore, community-based parameters based on these microbiota (e.g. ‘taxon-free’ traits, body-size spectrum, trophic-functional features and functional diversity) have been widely used as bioindicators for bioassessment of environmental/ecological quality status, because of their rapid responses to natural and anthropogenic impacts on the environment (Cairns & Henebry, 1982; Peters, 1983; Norf et al ., 2007; Xu et al ., 2011, 2014; Zhang et al ., 2013; Abdullah Al et al ., 2017, 2018).…”

Environmental Parameters and Substrate Type Drive Microeukaryotic Community Structure During Short-Term Experimental Colonization in Subtropical Eutrophic Freshwaters

“…Uher et al (2005) found no connection between substrate type and algal communities on stone in southeastern Spain. Previous studies of microbial biofilms mostly concentrated on a single type of aquatic environment such as lakes ( Xu et al, 2005 ; Jiang et al, 2007 ) or coastal seas ( Xu et al, 2009 ; Abdullah Al et al, 2018 ; Sikder and Xu, 2020 ; Sikder et al, 2020 ). Few studies have compared microeukaryotic community assemblies on substrates in different aquatic fluctuating conditions ( Battin et al, 2003 ; Besemer et al, 2007 ), even though it is recognized that current and tide play important role in microeukaryotic colonization ( Xu et al, 2009 ).…”

“…Most biofilm-dwelling microeukaryotes are primary consumers and play an important role in controlling the transfer of energy to higher trophic levels in aquatic microbial food webs ( Abdullah Al et al, 2018 ). Microeukaryotes are diverse and abundant in subtropical freshwater systems, because of high spatial and temporal heterogeneities ( Chen W. et al, 2019 ).…”

Abordagem funcional no estudo da comunidade de ciliados em uma estação de tratamento de esgoto combinada UASB-lodo ativado

“…Dentre os índices e parâmetros analisados, a riqueza de espécies e a riqueza funcional foram correlacionadas positiva e significativamente, visto o baixo número de espécies de ciliados e o grande número de traços atribuídos. Em estudos em ETE's operadas por lodos ativados, com maior número de espécies de ciliado ativas (CURDS & COCKBURN, 1970a, 1970bMADONI et al, 1993;SALVADÓ et al, 1995;MARTÍN-CERECEDA et al, 1996;ZHOU et al, 2007;DUBBER & GREY, 2011), haverá potenciais novos resultados, tal como demonstrado em outros estudos sobre a comunidade de ciliados em ambiente límnicos e marinhos (XU et al, 2016;ZHONG et al, 2017;AL et al, 2018aAL et al, , 2018bXU, Y. et al, , 2018b, LIU et al, 2019XU & SONINEN, 2019;ZHONG et al, 2019;GUI et al, 2020;XU et al, 2020 (SMETI et al, 2019). Por estes motivos a biodiversidade deve ser estudada no contexto das medidas clássicas e também da estrutura e funcionamento da comunidade (FRAINER et al, 2014).…”
