A description of the nymph of Anacroneuria ofaye Froehlich (Plecoptera: Perlida...
Novaes, Marcos Carneiro [UNESP]; Da Conceição Bispo, Pitágoras [UNESP]; Higuti, JanetMade available in DSpace on 2022-04-29T06:01:24Z (GMT). No. of bitstreams: 0 Previous issue date: 2012-11-13; The Neotropical genus Anacroneuria (Perlidae) is represented by more than 300 species. Among the Brazilian Anacroneu-ria, only the nymphs of two species have been described. In this paper, we described the nymph of A. ofaye Froehlich and an apparatus for rearing this genus. This is the first record of A...
Scale-dependent patterns of metacommunity structuring in aquatic organisms acro...
Lansac-Tôha, Fernando M.; Bini, Luis M.; Heino, Jani; Meira, Bianca R.; Segovia, Bianca T.; Pavanelli, Carla S.; Bonecker, Claudia C.Made available in DSpace on 2021-06-25T10:18:09Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-04-01; Aim: Evaluating how groups of organisms vary in dispersal capability and how environmental, spatial and temporal signals vary across multiple scales is critical to elucidating metacommunity theory. We examined whether the relative contributions of environmental, spatial and hydrological factors have dif...
Diel variation of aquatic insect drift in streams of Southern Brazil
Campos, Ramiro de; Rosa, Jonathan; Higuti, Janet; Buggenhagen, Tayane Cristina; Krawczyk, Ana Carolina de Deus BuenoSome organisms, such as aquatic insects, are transported from the upstream to downstream region of streams through a process called drift. This process occurs in passive and active ways and can be variable throughout the day, mainly between the nocturnal and diurnal periods. Here, we evaluate the periodicity of the drift of aquatic insects in two streams of the Middle Iguaçu basin, southern region of Brazil. We...
A global database for metacommunity ecology, integrating species, traits, envir...
Jeliazkov, Alienor; Mijatovic, Darko; Chantepie, Stéphane; Andrew, Nigel; Arlettaz, Raphaël; Barbaro, Luc; Barsoum, Nadia; Bartonova, AlenaThe use of functional information in the form of species traits plays an important role in explaining biodiversity patterns and responses to environmental changes. Although relationships between species composition, their traits, and the environment have been extensively studied on a case-by-case basis, results are variable, and it remains unclear how generalizable these relationships are across ecosystems, tax...

Fatores reguladores da biodiversidade de Ostracoda (Crustacea) no vale aluvial ...
Higuti, JanetA identificação de fatores reguladores da biodiversidade tem se tornado um dos principais campos de pesquisas ecológicas nas últimas décadas. Ambos os processos locais e regionais podem influenciar a biodiversidade em escalas temporais e espaciais. A diversidade e abundância de ostrácodes foram utilizadas para testar a significância de uma variedade de fatores que poderiam potencialmente regular a biodiversidad...
Morphological and molecular characterization of Corbicula (Mollusca, Bilvalvia)...
Bagatini, Yara Moretto; Panarari, Renata de Souza; Higuti, Janet; Benedito-Cecilio, Evanilde; Prioli, Alberto José; Prioli, Sonia Maria Alves PintoThe purpose of the present study was to verify, using RAPD and ISSR molecular techniques associated with the morphological characterization of bivalve shells, if the morphologically distinct specimens of Corbicula fluminea sampled at Rosana Reservoir belong to different species. The foot muscle tissue of the three groups (G1, G2, and G3) of Corbicula was removed and frozen in liquid nitrogen to the DNA analyze....
Spatial variation of the benthic community in the Corumbá reservoir, Goiás, Bra...
Moretto, Yara; Higuti, Janet; Takeda, Alice MichiyoThe benthic community composition and abundance were analyzed in three stations of the Corumbá reservoir. Collections were undertaken at the margin and the center of the stations, aiming to analyze the abiotic parameters affecting this community. Variables such as depth, dissolved oxygen and sediment type were the main factors that determined the benthic community structure. Fauna was abundant in the marginal r...
Structure and dynamics of the cyclopoid copepod (Crustacea) assemblage associat...
Velho, Luiz Felipe Machado; Lansac-Tôha, Fabio Amodêo; Takeda, Alice Michyio; Higuti, Janet; Franco, Gilza Maria de SouzaSpatial and temporal variation was analyzed in the composition, diversity, and abundance of cyclopoid copepods associated with Eichhornia azurea (Swartz) Kunth in two lotic environments of the Upper Paraná river basin. Sixteen cyclopoid taxa were identified. There were no differences in the composition of copepod species between environments or hydrological phases. Cyclopoids were generally more abundant during...
