“…The latter pattern is consistent in part with that reported by MENENDEZ et al (2011MENENDEZ et al ( , 2012 for the main channel in the inner zone of the BBE since those authors found the highest abundances at the bottom throughout the tidal cycle. Other authors have also found a higher abundance of A. tonsa at depth during the ebb tide in estuaries (TRINAST, 1975;GONÇALVES et al, 2012). This fact has been also reported for E. americana by Bakker et al (1977).…”

“…Deeper insight into the variability of these ecosystems at different temporal-spatial scales is therefore a prerequisite to understanding the composition and abundance dynamics of estuarine mesozooplankton. Tides, winds and estuarine circulation influence the composition and abundance of estuarine zooplankton, also affecting zooplankton assemblage composition and therefore their spatial (vertical and horizontal) distribution (HILL, 1991;WIAFE;FRID, 1996;DAUVIN et al, 1998;KIMMERER et al, 1998KIMMERER et al, , 2002PEITSCH et al, 2000;ROMAN et al, 2001;MOUNY;DAUVIN, 2002;NAYLOR, 2006;THORISSON, 2006;DEVREKER et al, 2008DEVREKER et al, , 2010HSIEH et al, 2010;UEDA et al, 2010;SCHMITT et al, 2011;MENENDEZ et al, 2011MENENDEZ et al, , 2012GONÇALVES et al, 2012;DA COSTA et al, 2013). The temporal variation in environmental conditions is another main factor strongly affecting the occurrence, features and distribution of zooplankton assemblages (DAUVIN et al, 1998;MARQUES et al, 2009;DUTTO et al, 2012).…”

Tidal effects on short-term mesozooplankton distribution in small channels of a temperate-turbid estuary, Southwestern Atlantic

et al. 2015

The short-term variability of mesozooplankton distribution and physicochemical variables was examined in two different channels of the Bahía Blanca Estuary, Argentina, during two tidal cycles. All the physicochemical measurements and mesozooplankton sampling were performed at a fixed site during approximately 22-23 h at 3-h intervals. Pumps were used to obtain surface and bottom mesozooplankton samples and the water speed of each stratum was measured with an Acoustic Doppler Current Profiler (ADCP). In all, 23 mesozooplanktonic taxa belonging to four phyla (Arthropoda, Annelida, Echinodermata and Chordata) were identified. The most abundant taxa during the two tidal cycles were Balanus glandula larvae, Eurytemora americana and Acartia tonsa. A discernible variability in the water conditions and vertical mesozooplankton distribution (VMD) different from that known for the estuary's main channel, was found in the other two selected channels. VMD varied during the tidal cycle in both channels in accordance with the channel's geomorphology and water dynamic characteristics of each of them. The variation of the abundance of the different taxa during ebb and flood currents might indicate the existence of a tidal vertical migration of the mesozooplankton as a response to particular dynamic water conditions. A variação de curto prazo da distribuição do mesozooplâncton e das variáveis físico-químicas foi examinada em dois diferentes canais do Estuário de Bahia Blanca, Argentina, durante dois ciclos de maré. As medidas físico-químicas e a amostragem do zooplâncton foram realizadas em dois locais fixos durante aproximadamente 22-23 horas, com intervalos de 3 horas. Bombas foram utilizadas para obter amostras de zooplâncton na superfície e no fundo e a velocidade da água em cada estrato foi medida com o Perfilador Acústico de Corrente (ADCP). Ao todo, foram identificados 23 taxa mesozooplanctônicos pertencentes a 4 filos (Arthropoda, Annelida, Echinodermata e Chordata). Os grupos mais abundantes durante os dois ciclos de maré foram larvas de Balanus glandula, além de Eurytemora americana e Acartia tonsa. Nos dois canais selecionados foi identificada uma variação nas condições da água e na distribuição vertical do mesozooplâncton (DVZ) diferente daquela conhecida para o canal principal do estuário. DVZ variou durante o ciclo de maré em ambos os canais de acordo com a geomorfologia e características da dinâmica das águas existente em cada um deles. A variação na abundância dos diferentes taxa durante as marés vazante e enchente poderia estar indicando a existência de migração vertical do mesozooplâncton em resposta a uma determinada condição dinâmica da água.

“…Environmental stressors interfere with sub-organismal constituents such as cells and tissues, therefore, biomolecular and biochemical levels are sensitive and quick-responding indicators to stressors (Adams and Greeley, 2000). Indeed, alteration in FA composition is a sensitive early warning bio-indicator of stress, as evidenced by numerous studies (Gonç alves et al, 2012b(Gonç alves et al, , 2016Maazouzi et al, 2008;Ramírez et al, 2013;Sánchez-Muros et al, 2013).…”

“…Fatty acid (FA) analysis is a well-established tool for studying trophic interactions in aquatic habitats (Kelly and Scheibling, 2012). Biological specificity of FA and the fact that in most cases they are transferred from primary producers to higher trophic levels without change, make them suitable as bio-indicators (Gonç alves et al, 2012a(Gonç alves et al, , 2016. However, primary consumers such as benthic harpacticoid copepods have the ability to bioconvert FA (De Troch et al, 2012).…”

“…In this work three planktonic species were used: the diatom Thalassiosira weissflogii, the copepod Acartia tonsa and the nauplii of the brine shrimp Artemia franciscana. The estuarine copepod Acartia tonsa is one of the most abundant copepod species in the Mondego estuary (Gonç alves et al, 2010b). The brine shrimp Artemia franciscana is a widespread invasive species in Portuguese marine waters (Pinto et al, 2013) and the marine diatom Thalassiosira weissflogii is a sensitive test-organism for seawater toxicity tests (Araújo and Souza-Santos, 2013) and is widely used as food source for zooplankton (Fields et al, 2011).…”

Biochemical and toxicological effects of organic (herbicide Primextra® Gold TZ) and inorganic (copper) compounds on zooplankton and phytoplankton species

et al. 2016

View full text Add to dashboard Cite

a b s t r a c tIn Europe, mainly in the Mediterranean region, an intensive usage of pesticides was recorded during the past 30 years. According to information from agricultural cooperatives of the Mondego valley (Figueira da Foz, Portugal), Primextra ® Gold TZ is the most used herbicide in corn crop fields and one of the 20 best-selling herbicides in Portugal. Copper is mainly used in pesticide formulations. This study aims to determine the ecotoxicological and biochemical (namely fatty acid profiles) effects of the herbicide Primextra ® Gold TZ and the metal copper on marine plankton. The organisms used in this study are three planktonic species: the marine diatom Thalassiosira weissflogii, the estuarine copepod Acartia tonsa and nauplii of the marine brine shrimp Artemia franciscana. Fatty acids (FAs) are one of the most important molecules transferred across the plant-animal interface in aquatic food webs and can be used as good indicators of stress. The conducted lab incubations show that T. weissflogii is the most sensitive species to the herbicide followed by A. tonsa (EC 50 = 0.0078 mg/L and EC 50 = 0.925 mg/L, respectively), whereas the copepod was the most sensitive species to the metal followed by T. weissflogii (EC 50 = 0.234 mg/L and EC 50 = 0.383 mg/L, respectively). A. franciscana was the most tolerant organism both to the herbicide and to the metal (EC 50 = 20.35 mg/L and EC 50 = 18.93 mg/L, respectively). Changes in the FA profiles of primary producer and primary consumers were observed, with the increase of saturated FA and decrease of unsaturated FA contents, especially of highly unsaturated FAs that can be obtained mainly from food and therefore are referred to as 'essential FA'. The study suggests that discharges of Primextra ® Gold TZ or other pesticides mainly composed by copper may be a threat to plankton populations causing changes in the FA contents and thus in their nutritive value, with severe repercussions for higher trophic levels and thus the entire food web.
