Macroinvertebrates inhabiting the tank leaf terrestrial and epiphyte bromeliads at Reserva Adolpho Ducke, Manaus, Amazonas

The aim of this work was to investigate the diversity of macroinvertebrates and also verify if the abundance and diversity of Diptera were influenced by the abiotic factors. The samples were collected from the epiphytic and terrestrial bromeliads G. brasiliensis (1 and 3m) in wet and dry seasons at Reserva Adolpho Ducke analyzed total of 144 samples were analyzed from a total of 15,238 individuals collected. These conatined 14,097 insects and, among these, 8,258 were immature Diptera, represented by eight most abundant families: Chironomidae, Ceratopogonidae and Culicidae. The relationship of Diptera diversity was influenced by the seasons and stratifications (p= 0.01); the abundance was influenced by the volume of water (p= 0.02) and the relationship between the season and volume of water in the terrestrial bromeliads was significant (p= 0.01). This study represented the first contribution to knowledge of community of macroinvertebrates associated to bromeliads G. brasiliensis in Central Amazon

Anchored phylogenomics of burrowing mayflies (Ephemeroptera) and the evolution of tusks : Phylogeny of burrowing mayflies

This study investigated the phylogenetic relationships among seven burrowing mayfly families. Genetic data from four ribosomal DNA genes (12S, 16S, 18S and 28S) generated with Sanger sequencing, 448 protein-coding loci generated using a novel hybrid enrichment probe set and available RNAseq and genome assembly for 19 ingroup taxa and four outgroup taxa. Maximum likelihood and Bayesian analyses were carried out to estimate phylogenetic relationships. The results indicated that Potamanthidae, Euthyplociidae, Behningiidae and Palingeniidae were recovered as monophyletic. Ephemeridae was not monophyletic. Mandibular tusks evolved in the common ancestor of burrowing mayflies and were lost in the lineage leading to Behningiidae
