Resumo(s)
Bryophytes are poikilohydric organisms that play a key role in ecosystems, while some of
them are also resistant to drought and environmental disturbances but present a slow growth rate.
Moss culture in the laboratory can be a very useful tool for ecological restoration or the development
of urban green spaces (roof and wall) in the Mediterranean region. Therefore, we aim to: (i) determine
the optimal culture conditions for the growth of four moss species present in the Mediterranean
climate, such as Bryum argenteum, Hypnum cupressiforme, Tortella nitida, and Tortella squarrosa; (ii) study
the optimal growth conditions of the invasive moss Campylopus introflexus to find out if it can be a
threat to native species. Photoperiod does not seem to cause any recognisable pattern in moss growth.
However, temperature produces more linear but slower growth at 15 C than at 20 and 25 C. In
addition, the lower temperature produced faster maximum cover values within 5–8 weeks, with at
least 60% of the culture area covered. The study concludes that the culture of moss artificially in the
organic gardening substrate without fertilisers is feasible and could be of great help for further use
in environmental projects to restore degraded ecosystems or to facilitate urban green spaces in the
Mediterranean area. Moreover, this study concludes that C. introflexus could successfully occupy the
niche of other native moss species, especially in degraded areas, in a future global change scenario
