Seven new species of detritivorous and phytoplanktivorous haplochromines from Lake Victoria Naturalis
Zeeuw, M.P. de; Mietes, M.; Niemantsverdriet, P.; Huurne, S. ter; Witte, F..
Seven new species of haplochromine cichlids from Lake Victoria are described. They comprise four detritivorous and three phytoplanktivorous species. Their affinities to other Lake Victoria haplochromines are discussed.

Glyphosate Impact on Arthropods Associated to Roundup Ready and Conventional Soybean (Glycine max L.) Planta Daninha
PEREIRA,J.L.; PEREIRA,R.R.; RESENDE-SILVA,G.A.; JAKELAITIS,A.; SILVA,A.A.; PICANÇO,M.C..
ABSTRACT: This study aims to evaluate the impact of glyphosate-resistant soybean and its management with glyphosate on the canopy arthropod community. We study the direct impact of the insertion of the resistance gene and the indirect impact of management practices, specifically herbicide application. To do this, we use the following treatments: non-GM and GM soybean with mechanical weed control and GM soybean with one and three applications of glyphosate. Arthropods in the crop canopy were sampled over time in all treatments. The incorporation of the glyphosate resistance gene did not affect the richness and abundance of arthropods in the plant canopy. Glyphosate application reduced the richness of predators and chewing and sucking phytophagous arthropods...

Neotropical woodlice (isopoda) colonizing leaf-litter of pioneer plants in a coal residue disposal environment Rev. Bras. Ciênc. Solo
Podgaiski,Luciana Regina; Quadros,Aline Ferreira; Araujo,Paula Beatriz; Rodrigues,Gilberto Gonçalves.
The irregular disposal of coal combustion residues has adverse impacts on terrestrial ecosystems. Pioneer plants and soil invertebrates play an important role in the recovery of these areas. The goal of this study was to investigate the colonization patterns of terrestrial isopods (Oniscidea) in leaf litter of three spontaneous pioneer plants (grass - Poaceae, shrub - Euphorbiaceae, tree - Anarcadiaceae) at sites used for fly ash or boiler slag disposal. The experiment consisted of eight blocks (four per disposal site) of 12 litter bags each (four per plant species) that were randomly removed after 6, 35, 70 or 140 days of field exposure. Three isopod species were found in the litter bags: Atlantoscia floridana (van Name, 1940) (Philosciidae; n = 116),...
