Background
Neckera borealis Nog., also simply called Neckera, is a species of moss classified in the
Bryophyta division and Bryopsida class. Mosses are non-vascular plants that lack true roots, stems, and leaves. Instead, they have leaf-like structures called phyllids that absorb water and nutrients. Mosses reproduce via spores rather than seeds and are found in a wide range of habitats worldwide.
Morphology and Identification
Neckera borealis forms mats or wefts of glossy, yellowish-green phyllids. The phyllids are oblong to ovate-lanceolate in shape, with a rounded to obtuse apex. They have a strong costa (midrib) that extends 3/4 or more of the phyllid length. The stems are creeping to ascending, irregularly branched, and can reach 5-10 cm long.
One key identifying feature of N. borealis is its undulate (wavy) phyllid margins, especially near the apex. The seta (stalk bearing the capsule) is 8-15 mm long and smooth. Capsules are erect and cylindrical, with a conical operculum (lid).
Global Distribution and Habitat
Neckera borealis Nog. has a wide distribution, found in North America, Europe, and Asia. It typically grows on tree trunks, logs, and rocks in moist, shaded forests. This moss prefers humid environments and is often found near streams or in riparian zones.
In North America, N. borealis ranges from Alaska to Newfoundland, south to California and North Carolina. It is common in the Pacific Northwest and the Appalachian Mountains. In Europe, it extends from Scandinavia to the Mediterranean region and east to the Caucasus. Asian populations are found in Japan, China, and the Russian Far East.
Ecological Roles and Adaptations
Like other mosses, Neckera borealis plays important ecological roles:
Moisture retention: Moss mats help retain moisture in the environment, preventing soil erosion and providing habitat for moisture-loving organisms.
Carbon sequestration: Mosses are significant carbon sinks, absorbing CO2 from the atmosphere and storing it in their tissues and the soil.
Nutrient cycling : As mosses decompose, they release nutrients back into the ecosystem, supporting the growth of other plants.
Habitat provision: Many small invertebrates, such as tardigrades, rotifers, and nematodes, live among moss phyllids. Some birds also use mosses for nesting material.
N. borealis has several adaptations that allow it to thrive in its preferred habitats:
- Poikilohydry: Like most mosses, it can tolerate desiccation and quickly rehydrate when water becomes available.
- Shade tolerance: Its glossy phyllids efficiently capture light in low-light environments of shaded forests.
- Substrate versatility
: It can grow on various substrates, including bark, wood, and rock.
