Baetidae (Ephemeroptera) na região sudeste do Brasil: novos registros e chave para os gêneros no estágio ninfal

Abstract: -In order to complement and integrate the knowledge regarding the fauna of Baetidae from Southeastern Brazil, thirteen species and nine genera of this family are recorded. Out of the twenty small minnow mayflies genera reported from Brazil, only five were not found for the region. A checklist of the species reported, including their distribution and pertinent bibliography, is presented. A pictorical key to nymphs is proposed for the identification of the genera in Southeastern Brazil. KEY WORDS: Aquatic insect… Show more

“…Stomach content was analysed under stereo microscope and quantified using the Volumetric (V O ) and Frequency of Occurrence (F O ) methods (Hyslop, 1980). Diet items were identified according to the literature (Salles et al, 2004;Triplehorn and Johnson, 2005;Passos et al, 2007;Mugnai et al, 2010) Kawakami and Vazzoler (1980) and adapted by Hahn et al (1997), according to the equation: IA i = (F i *V i )/Σ F i *V i )*100, where i = 1, 2, … n food items; F i = frequency of occurrence of a given food item; V i = volume of a given food item. Food items were grouped according to type (animal and vegetal) and origin (autochthonous and allochthonous).…”
