BBS Survey of Reproductive Phenology of Common British Bryophytes
As recently announced by Jeff Bates in Field Bryology we would like to invite BBS members to submit annual records of sporophyte development for some widely distributed species from chosen localities that they can revisit annually.
1. Species should be selected from the list provided
Please select as many or as few species as you wish from this list of common British bryophytes:
Atrichum undulatum, Brachythecium rutabulum, Bryum capillare, Campylopus introflexus, Ceratodon purpureus, Dicranella heteromalla, Dicranoweisa cirrata, Diplophyllum albicans, Fissidens bryoides, Fissidens taxifolius, Grimmia pulvinata, Hypnum cupressiforme var. cupressiforme, Isothecium myosuroides, Lophocolea heterophylla, Mnium hornum, Orthodontium lineare, Orthotrichum affine, Orthotrichum diaphanum, Pellia epiphylla, Polytrichastrum formosum, Polytrichum juniperinum, Pogonatum aloides, Radula complanata, Rhynchostegium confertum, Tortula muralis.
Please assign a unique plant ID to your species patch e.g. SP-A.und-01
Using the form provided please record the dates on which the following observations (stages) are made:
For a moss:
1m. The first five caplyptrae become noticeable among the perichaetial leaves
For a liverwort:
1l. The first five green capsules become visible inside perianths or (Pellia) calyptrae
Habitat - In the form, you are asked to provide details that might help interpretation, including patch size, substratum, shading and exposure. Please provide any further information in the Additional comments column – the more information included, the more valuable are your records.
Under ‘year of study’ please select ‘first’, ‘second’, ‘third’, etc., so that the dates can be compared easily with those from previous or later observations of this species patch.
Looking forward to receiving your records,
