Whereas many nemerteans (ribbon worms; phylum Nemertea) can be identified from external characters if observed alive, many are still problematic. When it comes to preserved specimens (as in e.g. marine inventories), there is a particular need for specimen identifier alternatives. Here, we evaluate the utility of COI (cytochrome c oxidase subunit I) as a single-locus barcoding gene. We sequenced...

Studies that simulate recurrent drought events with subsequent episodes of rehydration better reflect natural conditions and allow visualization differential acclimatization responses resulting from memory tolerance mechanisms. Piper aduncum tuberculatum were grown in a greenhouse subjected to three successive cycles rehydration. After suspending irrigation, gas exchanges measured da...
