“…Behavioural changes or, in more recent cases such as diatoms, population changes, can be interpreted to extrapolate the environmental signals present. 1,2 Whilst useful during their application, these methods are often imprecise, unpredictable, and do not provide a historic account of signal detection. Bio-recorders may be the key to overcoming these obstacles.…”

Continuous monitoring of intra-and extra-cellular environments, ranging from open fields and rivers to within a single cell, is often limited by costly equipment, labour intensity or invasive techniques. It may, however, be possible to avoid these issues by developing a monitoring device on a much smaller scale. By applying novel synthetic biology techniques, it is now possible to engineer organisms with refined bio-recording capabilities, using DNA as a recording medium on which a cellular 'memory' of past events can be written. Through a variety of mechanisms, using recombinases, CRISPR nucleases, base editing, polymerases and prime editing, intra-and extracellular events can be recorded along with temporal, spacial and magnitude information.Here, the mechanisms developed for DNA-based bio-recording devices so far are assessed and discussed, within the context of the potential future applications of these devices.

The area of the city of Meknes (Morocco) undergoes anthropic pressure, which acts mainly on the rivers. River water is used, without preliminary treatment, for farm irrigation. A study of the impacts of anthropogenic activities on the distribution and biodiversity of benthic macroinvertebrates and water quality of the Boufekrane River (Meknes) was conducted. Four pristine stations from the upstream and two stations at the downstream receiving anthropogenic impacts were selected along the River. For 12 consecutive months (from January to December 2010), based on the SEQ-V.2 scoring system, water quality index classes, the upstream stations recorded significantly higher biological monitoring scores and better water quality indices than those of the downstream. Four variables are involved actively in the individualization of the physico-chemical environment: COD, dissolved oxygen, TSS and temperature. The total number of macrobenthic taxa and their overall richness indices and diversity indices were significantly higher at the upstream stations than at the downstream stations. The relationships between the physicochemical and the macrobenthic data were investigated by biotypology analysis (PCA and FCA) and Pearson correlation analysis. The analyses showed that the richness and diversity indices were generally influenced by the total suspended solids, chemical oxygen demand and the electric conductivity of the river water. This study also highlighted the impacts of anthropogenic activities on the distribution and species diversity of macrobenthic invertebrate. Some sensitive (Trichoptera and Ephemeroptera) and resistant species (Oligochaeta such as Tubifex sp.) are identified as potential bioindicators of clean and polluted river ecosystems, respectively, in Morocco rivers. The data obtained in this study supported the use of the bioindicator concept 174(Innovative Biotechniques for controlling water quality) for North Africa rivers because it is more efficient than conventional methods.
