Calcareous algae from Upper Albian - Cenomanian strata of the Potiguar basin (NE Brazil)
(2008-12-01)
Calcareous Albian-Cenomanian strata in the Potiguar basin yield a number of microfossils, among which are calcareous algae (Dasycladales and Corallinales). This data, together with an inventory of previous discoveries, ...
Invertebrados bentônicos: Relação entre estrutura da fauna e características do mesohabitat
(2016-01-01)
The formation of different mesohabitats, such as pools, riffles and runs, is common along the courses of stream ecosystems, and these are frequently accompanied by changes in the benthic fauna structure. In this paper, we ...

Is the microcosm approach using meiofauna community descriptors a suitable tool for ecotoxicological studies?
(Elsevier B.V., 2018-01-01)
The usual approaches used in ecological risk assessment have been based on individual and population level standard procedures. Although these have been important tools to assess adverse effects on ecosystems, they are ...
Effects of novobiocin and methotrexate on the benthic amphipod Ampelisca brevicornis exposed to spiked sediments
(Elsevier B.V., 2016-12-01)
