“…Throughout the life cycle, O. ciliata had nine instars, a number lower than that normally found for other chydorids (Table 2), such as for Chydorus pubescens (Santos-Wisniewski et al, 2006), Coronatella rectangula (Viti et al, 2013), Leydigia acanthocercoides (Murugan & Job, 1982) and Alonella excisa (Sharma & Sharma, 1998). The number of instars of O. ciliata recorded in the present study was close to 8.92 ± 1.23 instars, verified for O. longicaudis (Castilho et al, 2015).…”

This study the life cycle and quantify the secondary production of the cladoceran Oxyurella ciliata under controlled conditions in a laboratory and use molecular biology as a tool to investigate its genetic characteristics. The organisms were collected from Baia do Gerente, a pond from the Pantanal region, MS state, Brazil. They were acclimatized, maintained at a controlled temperature (25 ± 1 °C) and photoperiod (12/12h light-dark), fed with the microalgae Raphidocelis subcapitata and observed daily to obtain the data. O. ciliata had a high total egg production of 34.18 ± 9.68 eggs/female and an average longevity of 58.50 ± 16.30 days. These values differed from those previously reported for O. longicaudis, another congeneric species. There was an exponential growth of biomass until instar 6 and the largest secondary production was from the young to the adult phase, which corresponds to the beginning of the reproductive phase. The molecular data revealed that the genetic divergence between the sequence of O. ciliata and that of O. longicaudis is approximately 18 %, which seems high considering that both belong to the same genus. Comparing life cycle data and DNA Barcode, Oxyurella ciliata and O. longicaudis are very distant and have distinct morphological and biological characteristics, such as: body size, egg size, growth, fertility, longevity and development times. This study highlights the importance of molecular studies and information on the life cycle of neotropical cladocerans, in an integrated way, to have a better taxonomic and ecological interpretation of the species.

“…1 As previously reported, the northwestern region of São Paulo State is one of the least studied about zooplankton communities. It can be pointed out the works carried out by Silva & Matsumura-Tundisi (2005) & Santos-Wisniewski et al (2008 on planktonic microcrustaceans from reservoirs of this region. For Rocha & Guntzel (1999), cladocerans studies are still very limited for São Paulo State, whose lack of data allowed us to report some new occurrences of species for the State.…”

These new records (see Table 3) were based on recent inventories that didn't found these species in São Paulo State (Elmoor-Loureiro 1997, 2000, Rocha & Guntzel, 1999, SantosWisniewski et al 2002, Martins & Henry 2004, Casanova 2005, Santos-Wisniewski et al 2008.…”

Pelagic and littoral cladocerans (Crustacea, Anomopoda and Ctenopoda) from reservoirs of the Northwest of São Paulo State, Brazil

Abstract:There are few studies on the zooplankton from the northwestern region of São Paulo State, Brazil, compared to other regions of the State. Cladocerans are a very representative zooplankton group with high species diversity. Most of this diversity can be found at littoral zones of lakes and reservoirs, especially those occupied by macrophytes. This study was part of a thematic project FAPESP/BIOTA Program -The Virtual Institute of Biodiversity (www.biotasp.org.br), and its aim is to catalogue and analyze the distribution of cladoceran species (Crustacea, Anomopoda and Ctenopoda) in pelagic and littoral zones from small reservoirs in the northwest of the São Paulo State, in dry and rainy seasons. Zooplankton samplings were carried out in littoral and pelagic zone of 10 small shallow reservoirs (mean depth: 2.8 m) using a plankton 45 µm mesh net. Water physical and chemical parameters were also monitored with a multiparameter Horiba U10. pH and dissolved oxygen concentration were lower at rainy than dry seasons, indicating high decomposition rates of organic matter introduced from the rural environment, being the main factor contributing to reservoirs' eutrophication. Fifty eight cladocerans species were recorded, with four new occurrences for the São Paulo State. This high richness contrasts with the high devastation of the northwestern region in the State. During the two seasons, littoral zones presented higher cladoceran richness and diversity than pelagic zone. Littoral zones with higher macrophytes diversity also showed higher cladocerans richness and diversity than that with low macrophyte diversity. Littoral and pelagic zones comparisons emphasized the importance of studies on different regions of the aquatic environments, confirming the elevated richness in the littoral zone, as reported in previous works. This study revealed also the strong influence of the macrophyte community and the adjacent terrestrial environment, which is occupied by forest or agriculture. Resumo: A região noroeste paulista é uma das regiões com menor quantidade de dados sobre o zooplâncton, comparado a outras regiões do estado. Os Cladocera constituem um grupo bastante representativo do zooplâncton, apresentando elevada diversidade de espécies. A maior parte desta diversidade pode ser encontrada nas regiões litorâneas de lagos e reservatórios, especialmente aquelas ocupadas por muitas macrófitas. Como parte de um projeto temático mais amplo (Programa Biota-Fapesp -Instituto Virtual da Biodiversidade, www.biotasp.org. br), o presente trabalho tem o objetivo de caracterizar as comunidades de cladóceros (Crustacea, Anomopoda e Ctenopoda) pelágicos e litorâneos presentes em pequenos reservatórios na região noroeste do estado de São Paulo, nas estações seca e chuvosa. As amostragens foram realizadas tanto na zona litorânea quanto pelágica de 10 pequenos reservatórios rasos (média de 2,8 m), através de arrastos verticais com rede de plâncton de 45 µm de malha. Parâmetros físicos e químicos da água também foram avaliados utilizando...

The present study aimed to identify the Cladocera species present in 15 samples of zooplankton, taken occasionally between 1981 and 2001, from the Counties of Recife, Jaboatão dos Guararapes, Paulista e Escada (state of Pernambuco, Brazil). In total, 32 species were reported; 10 of them represent first records, which increased to 51 the number of species known to occur in Pernambuco state. The highest cladoceran species richness was observed in water bodies where macrophytes were more abundant and with more samples available.
