ADAPTAÇÃO METODOLÓGICA PARA ESTUDOS DE ORGANISMOS ZOOPLANCTÔNICOS"IN SITU", APLICADOS À PISCICULTURA Acta Amazonica
FIM,Jorge D. I.; HARDY,Elsa R..
Os organismos zooplanctônicos desempenham um importante papel na alimentação de larvas e pós-larvas de peixes, tanto na natureza, como em cativeiro em tanques de piscicultura. No aspecto do cultivo de zooplâncton cm massa, somente conhecendo-se os valores de alguns parâmetros importantes do ciclo de vida de um único indivíduo, em situações diversas, é que se pode avaliar se este estará respondendo de maneira adequada, ou não, a determinado tratamento aplicado. O trabalho mostra uma adaptação de mamadeiras plásticas comerciais para a utilização no estudo individualizado de microcrustáceos zooplanctônicos (cladóceros), em laboratório (aquários), viveiros de piscicultura, ou ambientes naturais (lagos e igarapés).

Can nearby eutrophic reservoirs sustain a differentiated biodiversity of planktonic microcrustaceans in a tropical semiarid basin? Anais da ABC (AABC)
DINIZ,LEIDIANE P.; MELO-JÚNIOR,MAURO DE.
ABSTRACT This paper aims to compare alpha and beta diversities of planktonic microcrustaceans from three reservoirs located nearby in a tropical semiarid basin. Our hypothesis was that alpha and beta diversities of the community are different, although the ecosystems are located close to each other. We carried out two sampling campaigns: dry and rainy seasons. The sampling of microcrustaceans and environmental variables (dissolved oxygen, chlorophyll a and nutrient) was performed at twelve stations and were distributed throughout the three zones (river, transition, and lacustrine), using a plankton net (45 µm). The reservoirs showed different uses and types of nitrogen predominance: Cachoeira (supply/nitrate), Borborema (sewage/ammonia) and Saco...

Concordance patterns in zooplankton assemblages in the UHE - Luís Eduardo Magalhães reservoir in the Mid-Tocantins river, Tocantins State, Brazil - doi: 10.4025/actascibiolsci.v33i2.7336 Biological Sciences
Bessa, Gisele Fernandes; Universidade Federal do Tocantins; Vieira, Ludgero Cardoso Galli; Universidade de Brasília; Bini, Luis Mauricio; Universidade Federal do Goiás; Reis, Deusiano Florêncio dos; Universidade Federal do Tocantins; Morais, Paula Benevides de; Universidade Federal do Tocantins.
The goal of this study was to evaluate the concordance amongst three zooplankton groups (Rotifera, Cladocera, and Copepoda) and between the zooplankton groups and the environmental variables in the Luis Eduardo Magalhães reservoir, in the Mid-Tocantins River, Tocantins State, Brazil. Concordance patterns were found in relation to environmental variables, cladocerans, and rotifers, although values were relatively low. These results indicate that one should be cautious about the use of indicative taxonomic groups to detect environmental changes, where divergent results annul extrapolation possibilities and indicate the existence of distinct environmental factors controlling different groups.

Conducta alimentaria de Daphnia ambigua Scourfield 1947, Moina micrura Kurz 1874 y Ceriodaphnia dubia Richard 1895 (Cladocera) frente a un gradiente de concentración de alimento RChHN
MARTINEZ,GINGER.
Debido a que Cladocera es el grupo de microfiltradores más abundante del zooplancton límnico y cuyas poblaciones se encuentran usualmente limitadas por alimento, la respuesta de los individuos frente a un gradiente de concentración de recursos tendría significativas implicancias sobre los patrones poblacionales y comunitarios. Se comparó la conducta alimentaria de Moina micrura, Ceriodaphnia dubia y Daphnia ambigua (Cladocera) frente a las microalgas Chlorella sp. y Oocystis sp. (Chlorophyceae) mediante los siguientes parámetros: Tasa de Ingesta Máxima (Imax), Concentración Limitante Incipiente (CLI) y Eficiencia de Consumo (b), los cuales fueron obtenidos a través de un modelo de respuesta funcional. Los resultados mostraron que D. ambigua presentó las...

Diel changes in embryonic maturation in two species of marine cladocerans in Guanabara Bay, Rio de Janeiro, Brazil Zoologia
Marazzo,Andrea; Valentin,Jean L..
Two species of marine cladocerans, Penilia avirostris Dana, 1852 and Evadne tergestina Claus, 1877 were collected in thirteen samples at a fixed station in Guanabara Bay, Rio de Janeiro (30-meter depth) by means of vertical tows with a 200 µm mesh size net at different times from September 12th to 15th, 1995. The parthenogenetic females of Evadne tergestina bore mature embryos (with pigmented eye) only in the samples collected at night, whereas Penilia avirostris at any time of day. This phenomenon was interpreted based on the greater visibility of the Evadne tergestina brood: one of the benefits for embryo maturing during the darkness period would be a decrease of predation on gravid females.

Diel vertical migration patterns of three zooplankton populations in a Chilean lake RChHN
RAMOS-JILIBERTO,RODRIGO; CARVAJAL,JOSÉ L.; CARTER,MAURICIO; ZÚÑIGA,LUIS R..
In this work we analyzed the depth-distribution, at noon and midnight, of three zooplankton populations which are common inhabitants of lakes from central Chile and coexist in lake El Plateado. The species were Tumeodiaptomus diabolicus, Diaphanosoma chilense and Bosmina longirostris. Also, we analyzed the association between the depth-specific abundances of the groups and the depth-specific temperature and oxygen values during the sampling period. Our results show that: (1) the three population exhibited diel vertical migration during part of the year; (2) T. diabolicus and D. chilense exhibited the normal pattern of vertical migration, and B. longirostris presented both the normal and the reverse pattern; (3) for all species and most dates, zooplankters...

Distribution and biological aspects of the introduced speciesMoina macrocopa (Straus, 1820) (Crustacea, Cladocera) in the semi-arid central region of Argentina Biota Neotropica
Vignatti,Alicia María; Cabrera,Gabriela Cecilia; Echaniz,Santiago Andrés.
Moina macrocopa is common in eutrophic water bodies. Two subspecies have been described: M. macrocopa macrocopa (Straus, 1820), whose original distribution was restricted to the Old World, and M. macrocopa americanaGoulden, 1968, recorded only in North America. In 1994, the species was found in Bolivia, and in 1997 it was found in the northeast of Argentina. As the specimens belonged to M. macrocopa macrocopa in both cases, the authors suggested that it may have been introduced from the Old World by anthropogenic means. The aim of this study was to assess the distribution of M. macrocopa in La Pampa (Argentina), and provide information on its population characteristics under natural conditions. The species was recorded in six out of more than 100 water...

Do littoral macrophytes influence crustacean zooplankton IPB - Escola Superior Agrária
Geraldes, Ana Maria; Boavida, Maria José.
In a meso-eutrophic reservoir, cladoceran and copepod assemblages were characterised in two sampling sites: One located in the pelagic zone (site 1) and the other in the shallow littoral zone (site 2), the latter colonised by emergent macrophytes. Samples were collected biweekly from June to July 2001 and from May to July 2002 at the two sites. At site 1, crustacean zooplankton samples were obtained by vertical hauls using a Wisconsin type net of 64 mm mesh size. At site 2 several random samples were obtained using a van Dorn bottle. Those samples were pooled together and the total sample was sieved through a 64 mm mesh size. Macrophyte relative abundance for each species was visually estimated. Macrophyte community was composed of Glyceria declinata,...

El rol del frente de mareas de Península Valdés en el control de la comunidad zooplanctónica OceanDocs
Derisio, C..
The Península Valdés tidal front was studied in its rol in the control of the spatial distribution, abundance, assemblages, diversity and life histories of the zooplankton community using samples from two oceanographic surveys. Although the front showed in general high zooplankton abundances, highest values, mainly due to the presence of immature stages of copepods, were recorded in the transitional and stratified zones coinciding with highest values of chlorophyll a. The zooplankton groups showed a distinctive spatial distribution across the front. The results showed that this front did not exert any control on zooplankton composition and diversity, but did on the abundance. In the homogeneous zone the harpacticoid copepods were more abundant, followed by...

High temperatures and absence of light affect the hatching of resting eggs of Daphnia in the tropics Anais da ABC (AABC)
Paes,Thécia A.S.V.; Rietzler,Arnola C.; Pujoni,Diego G.F.; Maia-Barbosa,Paulina M..
Temperature and light are acknowledged as important factors for hatching of resting eggs. The knowledge of how they affect hatching rates of this type of egg is important for the comprehension of the consequences of warming waters in recolonization of aquatic ecosystems dependent on dormant populations. This study aimed at comparing the influence of different temperature and light conditions on hatching rates of Daphnia ambigua andDaphnia laevis resting eggs from tropical environments. The ephippia were collected in the sediment of three aquatic ecosystems, in southeastern Brazil. For each lake, the resting eggs were exposed to temperatures of 20, 24, 28 and 32 °C, under light (12 h photoperiod) and dark conditions. The results showed that the absence of...

Identification key for the Brazilian genera and species of Aloninae (Crustacea, Branchiopoda, Anomopoda, Chydoridae) Pap. Avulsos de Zool. (São Paulo)
Sousa,Francisco Diogo Rocha; Elmoor-Loureiro,Lourdes Maria Abdu.
Abstract Since early 2000 years, the knowledge about the taxonomy of Aloninae (Cladocera: Chydoridae) has been in rapid progress. For this reason, the most of Brazilian fauna was affected concerning nomenclature, besides an increase in the number of known genera and species. Thus, in this study, we bring an updated species list of Aloninae in Brazil, as well as identification keys based in current nomenclature and morphological standards. Our finding pointed to the occurrence of 46 valid species, belonging to 21 genera and three groups of Alona sensu lato. Two of these genera are endemic to Brazil. So far, South-East Asia and Brazil have the most well-studied Aloninae fauna in the entire planet.

Identification key for the Brazilian species and subspecies of the family Ilyocryptidae (Crustacea, Branchiopoda, Anomopoda) Pap. Avulsos de Zool. (São Paulo)
Sousa,Francisco Diogo Rocha; Elmoor-Loureiro,Lourdes Maria Abdu.
Abstract In recent years, an increase in knowledge about the diversity and biogeography of Brazilian Cladocera fauna has been evident. To keep up with these changes, it is opportune to carry out an update of the taxonomy and biogeography for the main cladoceran groups. Since 2008, some progress has been observed in Ilyocryptidae, with reports of four new taxa. In this study, an updated checklist of Ilyocryptidae from Brazil is provided, with a diagnosis for each cited taxon, as well as an identification key. Some of these taxa are considered rare; however, this issue might be an artifact of sampling. As this is the first in a series of papers compiling current information about Brazilian Cladocera, an identification key to orders and families occurring in...

Life history, biomass and production of Coronatella rectangula (Branchiopoda, Anomopoda, Chydoridae) from Minas Gerais Iheringia, Sér. Zool.
Viti,Thais; Wisniewski,Célio; Orlando,Tereza Cristina; Santos-Wisniewski,Maria José dos.
Species of Chydoridae provide the main diversity of the Cladocera. These organisms have been the subject of many studies; some dealing with their role in energy flow in aquatic ecosystems, since they inhabit the littoral region of water bodies which undergo the first impacts from anthropic activities. The aim of this study is to increase knowledge about the life cycle of Coronatella rectangula (Sars, 1861), a species found in several water bodies in the state of Minas Gerais, Brazil. The life cycle was determined by the culture of parthenogenetic females under controlled conditions in the laboratory. Experimental cultures were maintained in growth chambers at a constant temperature of 23.6(±0.5)ºC, through a 12 h light/12 h dark photoperiod. The organisms...

Metabolic Theory of Ecology and diversity of continental zooplankton in Brazil - doi: 10.4025/actascibiolsci.v34i1.9087 Biological Sciences
Pinese, Olívia Penatti; Universidade Federal de Goiás - UFG; Cassemiro, Fernanda Aparecida da Silva; Universidade de Brasília - UnB; Pinese, José Fernando; Universidade Federal de Uberlândia - UFU; Diniz-Filho, José Alexandre Felizola; Universidade Federal de Goiás - UFG.
Several ecological hypotheses try to explain geographical patterns in biodiversity. The Metabolic Theory of Ecology (MTE) predicts that temperature is the main determinant of richness patterns for ectothermic organisms and that the relationship between richness (lnS) and temperature (1/kT) is a linear relationship with angular coefficient (b) near -0.65. This study tested the MTE for continental zooplankton diversity in 63 lakes in Brazil. Copepoda, Cladocera and Rotifera, as well as the three groups combined, showed different patterns from that predicted by MTE, with b values equal to 0.871, 0.516, 0.720 and 0.901, respectively. Temperature explains 12.7% of the richness of Copepoda, 5.3% of Cladocera, 6.7% of Rotifera, and 11.4% of all zooplankton groups...

Phytophilous cladocerans (Crustacea, Anomopoda and Ctenopoda) from Paranã River Valley, Goiás, Brazil Zoologia
Elmoor-Loureiro,Lourdes M. A..
A rapid assessment survey identified 39 phytophilous cladocerans species from littoral zones of rivers, permanent and temporary lagoons, and swamps of the Paranã River Valley, Goiás, Brazil, 22 are registered for the first time in Central Brazil. Aspects of the taxonomy of some of these species are discussed. Cluster analysis (UPGMA) revealed two phytophilous cladoceran assemblages, characterized by higher or lower richness and relative abundance of species of the families Daphniidae and Moinidae (filter feeders), in comparison with the dominant families Chydoridae and Macrothricidae (scraper feeders).

Population dynamics of Pseudevadne tergestina (Branchiopoda: Onychopoda) in Guanabara Bay, Brazil BABT
Marazzo,Andrea; Valentin,Jean Louis.
Populations of Pseudevadne tergestina were studied in Guanabara Bay, southeastern Brazil, to assess temporal variations in density and population dynamics. Data on temperature, salinity and zooplankton samples were taken from the superficial water of a fixed station, every 3 - 4 days, from February 2 through August 1, 2000. The highest abundance of this species was observed in March, when densities varied widely, from 20 to 600 ind. m-3. Population parameters were calculated, such as birth rate (from 0.25 to 0.90 ind.-1.day-1), growth rate (from -1.30 to 2.09 day-1 ) and death rate ( from -1.6 to 1.9 day-1 ) Start of population could be attributed to the increase of temperature and to the hatching of resting eggs. The population collapsed in fall-winter,...
