The transfer may have been triggered by the large-scale liming of acidic mires.

Algal research that has its ups and downs…
Every so often you chance upon a scientific study that makes you think “What? That’s new or worthy of study (and publication…)?” I had that reaction when I saw the paper entitled, “Photosynthesis and circadian rhythms...

Exquisitely preserved tiny fossils are key for understanding moss evolution
Tiny 135-million-year-old moss fossils found in rocks from western Canada preserve exquisite anatomical details. These fossils open an unexpected window on moss evolution, as they allow for recognition of living moss...

Amazing moss and how to identify it
If I told you that during a 200m walk down a suburban London street I saw 13 different species from one group of organisms, you might struggle to imagine what I could have seen. You’d probably be even more surprised to...

Spore liberation in mosses
The ability to perform hygroscopic movements has evolved in many plant lineages and relates to a multitude of different functions such as seed burial, flower protection or regulation of diaspore release. In a recent...

Sex-specific morphology and physiology in Ceratodon purpureus
Separate sexes and biased sex ratios are common in bryophytes, yet little is known about how fine-scale, sex-specific morphological traits are correlated with physiology and population sex-ratios. Slate et al. analysed...

Moss, bringer of stability, and life…
This week Nigel Chaffey takes a closer look at mosses, the mighty colonisers of the land.
Spore settling velocity to assess moss dispersal rates
The settling velocity of diaspores is a key parameter influencing dispersal ability in wind-dispersed plants but remains largely undocumented in bryophytes. Zanatta et al. measured this parameter for nine species using...
Embryonic moss sporophytes can be hardened to desiccation tolerance
Embryos of the moss Aloina ambigua are inducibly desiccation tolerant (DT), requiring a slow-dry period to confer tolerance to air-dryness. Hardening to DT describes a condition of temporary tolerance to a rapid-dry...
Sporophyte desiccation tolerance in the moss Aloina
Stark and Brinda study cultured sporophytes and vegetative shoots from a single genotype of the moss Aloina ambigua.

The Node’s ‘a day in the life of a ...’ series is designed to give insights into the working of the labs – and the people – that try to unravel development,
The March 2013 issue of Annals of Botany is now Free Access
The March 2013 issue of Annals of Botany is now Free Access. The cover image is of two generations of moss, the younger sporophytes growing from the parent gametophyte. AJ Cann blogged about this paper last year. If you...

Moss: is the mother protecting the offspring, or holding it back?
Jessica M. Budke adds another dimension to a recent paper about the development of the calyptra in moss. Is there parent-offspring conflict?
Mum versus Dad: Parent–offspring conflict in mosses
Non-flowering plants have rather complex reproductive life cycles compared to the more familiar pattern of fertilization and seed formation seen in Angiosperms.
