Biogeographic distribution of bryoflora in the Mediterranean temporary ponds

open access: yes, 2015
In Europe, Mediterranean temporary ponds are indicated as priority natural habitats under the Habitats Directive 92/43/EEC: despite in those habitats bryophytes are recognized to have an important ecological function, there are very few studies on the ...

Broodstock management and seed production of tilapia and carp [PDF]

open access: yes, 1988
Bighead (Aristichthys nobilis) and silver (Hypophthalmichthys molitrix) carps were reared in ponds, pens and floating cages in Laguna Lake until maturity. Spontaneous gonadal maturation and rematuration of carp broodstock occurred within 2-2.5 years with

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

DNA-barcoding of non-biting midge larvae (chironomidae) in heavy metal polluted ponds [PDF]

open access: yes, 2019
Chironomids, or non-biting midges (Chironomidae), belong to the order of true flies (Diptera), and are frequently used as bio-indicators of water quality, where higher diversity levels reflect less polluted habitats.
