In the moss character menu, character states are grouped into one of six categories, each of these categories being described on its own page.
The page currently being viewed is indicated by both the white heading text above the character menu, as well as the lighter background on the character menu.
Following a link on the character menu leads to the corresponding content on the right panel which becomes highlighted with a lighter background and changing the page as required. It's also possible to navigate the pages sequentially by clicking on the links at the bottom of each page.
Each character state is described on the right panel, with a list of species showing that character, a photo of one of those species, and a couple of paragraphs describing the character state and its possible adaptive significance. A small left-pointing icon causes the corresponding character state link in the character menu to become highlighted, the page scrolling to that position.
Clicking on a photo opens the lightbox view showing a larger image. Navigation icons are provided below the image as follows:
Every boulder on the banks of the River Almond below the bridge at Buchanty, is covered with loose carpets of the moss Thamnobryum alopecurum, making the scene look almost like shoreline rocks covered with Fucus seaweeds.
The objective of these character list and table pages is to aid bryophyte identification through familiarisation with conspicuous features shown by different species. In addition, the lists should also help eliminate potential candidates, by highlighting situations where a specimen possesses characters inconsistent with the species being considered, while the tables may reveal some correlations between shared characters and taxonomic affinity, as well as with substrate and habitat.
