Última Larvae of Lutrochus germari (Lutrochidae: Coleoptera) and Stegoelmis sp. (Elmidae: Coleoptera): bore submerged woody debris in Neotropical streams Rev. Bras. Zool. Valente-Neto,Francisco; Fonseca-Gessner,Alaíde Aparecida. We report boring activity of larval Lutrochus germari Grouvelle, 1889 and Stegoelmis sp. in submerged woody debris and describe the resulting grooves and faecal pellet production. This ability of the larvae was shown by three types of evidence: 1) examination of collected woody debris, 2) rearing of larvae and 3) gut content analysis. The larvae excavated galleries deep into the submerged woody debris. This is the first record of gallery-forming behaviour in submerged woody debris by aquatic beetles, adding larval Lutrochus germari and Stegoelmis sp. to the list of borers in Neotropical aquatic systems.

Bras. Zool. Noro,Clarissa K.; Buckup,Ludwig. Parastacus defossus Faxon, 1898 is a fossorial crayfish species, which constructs its burrows in swampy areas in southeast Uruguay and in the state of Rio Grande do Sul, Brazil. The present field study was carried out in Lami, Porto Alegre, Rio Grande do Sul, Brazil, from May 2003 through August 2005. Environmental measurements (temperature, pH, dissolved oxygen, and water-table depth) of the water in the galleries were made monthly. Burrow morphology was analyzed by means of resin and gypsum casts. The spatial distribution and changes in the number and shape of the surface openings over time were observed in a 100 m² area. To estimate the spatial distribution of the openings, the observed distribution was compared with the expected distribution predicted...
