Ectonucleotidase and acetylcholinesterase activities in silver catfish (Rhamdia quelen) exposed to different salinities
In conclusion, this study showed that there is an enhancement in the NTPDase (ADP hydrolysis) and 5′-nucleotidase activities in the brains of silver catfish exposed to increased salinity. Therefore, the activities of these enzymes can act as markers of salinity changes. Highlights ► Silver catfish were gradually adapted to salinities of 0, 4 or 8 ppt. ► Blood AChE activity decreased significantly at 8 ppt. ► Brain AChE activity decreased significantly with salinity increases. ► There is an enhancement in the ADP hydrolysis in the brain of silver catfish. ► The activities of AChE and NTPDase can ac...

Genetic diversity of Brachystegia boehmii Taub. and Burkea africana Hook. f. across a fire gradient in Niassa National Reserve, northern Mozambique
In this study we report on the usefulness of ISSR markers to assess, for the first time, the genetic diversity in two typical miombo species, Brachystegia boehmii Taub. and Burkea africana Hook. f. across a fire gradient in the Niassa National Reserve (NNR). According to our data, ISSR seem to be a suitable molecular marker's system for biodiversity studies in both species, generating high levels of polymorphisms coupled with a convenient resolving power. The results point to a link between fire-tolerance and genetic diversity, as judged by the higher diversity levels observed in B. africana (fire-tolerant) and by the evol...
