Chironomids’ Relationship with Aeromonas Species

Chironomids (Diptera: Chironomidae), also known as non-biting midges, are one of the most abundant groups of insects in aquatic habitats. They undergo a complete metamorphosis of four life stages of which three are aquatic (egg, larva, and pupa), and the adult emerges into the air. Chironomids serve as a natural reservoir of Aeromonas and Vibrio cholerae species. Here, we review existing knowle...

Dynamics of metal adaptation in riverine chironomids.

The ability of the non-biting midge Chironomus riparius to survive and reproduce in metal polluted lowland rivers facilitates the opportunity to study micro-evolutionary processes in situ. However, due to larval drift, adapted midge populations are subject to regular immigration of non-adapted specimens from clean upstream river reaches. To examine the influence of non-adapted genes in adapted ...

Mine, mine, mine: information theory, infostation networks, and resource sharing

The Infostations wireless data network architecture features discontinuous coverage and ultra-high radio rates for burst transfers of information between base and mobile. It has been shown previously that the infostations architecture can greatly increase the capacity of wireless data systems at the expense of increased delivery delay. In this work we explicitly consider the multiple access iss...

Preventing acid mine drainage from mine tailings

Mining activity always has high impact on its surroundings, being waste deposition the cause of multiple and complex problems to the environment. One of them is Acid Mine Drainage (AMD), causing acid water percolation through large areas in the mine site. Portugal was a prosper tungsten producer from the beginning of the XX century, having its apogee during World War II. Nowadays there are mill...
