Sažetak
Ephemeral bryophytes are short-lived colonists that can germinate and finish their whole life cycle within a brief period during the vegetation season when favourable conditions occur. A significant number of these specialist species are associated with habitats such as margins of lakes, reservoirs and rivers. While conducting the national monitoring of the surface waters in 2016 and 2017 natural and artificial water bodies throughout Croatia were surveyed and water margins were inspected for eventual ephemeral bryophytes. We recorded a new species for the bryophyte flora of Croatia - Physcomitrium eurystomum Sendtn. on the margins of the Lake Biljsko Jezero, an oxbow lake of the Drava River near Osijek. Furthermore, a rare ephemeral species Physcomitrella patens (Hedw.) Bruch & Schimp. Was confirmed for the flora of Croatia. Physcomitrella patens grew in the drawdown zone of the Lake Biljsko Jezero, the Kruščica Reservoir in Lika, the Lake Sakadaš in Baranja and three rivers in Moslavina – Rajić, Ilova and Trebež. During our research rare ephemeral species Riccia cavernosa Hoffm., R. bifurca Hoffm., R. fluitans L. and Leptobryum pyriforme (Hedw.) Wilson were also recorded. Although mentioned species and their habitats are considered relatively rare and threatened in Europe, the low number of records in Croatia is to a considerable extent the result of insufficient research done into ephemeral habitats and bryophyte flora in general.
