How do I know what type of liverwort I have?
There are two sorts of liverworts; leafy liverworts have a stem and leaves and resemble a moss, whereas thallose or thalloid liverworts have a simple strap of tissue with no stem or leaves. Leafy liverworts can form erect cushions and turfs while some are creeping and closely apressed to rock or tree.
What are the two types of liverworts?
The 2000 classification divides the liverworts into two classes: Marchantiopsida and Jungermanniopsida. All the complex thallose liverworts are in the former and all the leafy liverworts in the latter.
What are common liverworts?
The Marchantiophyta (/mɑːrˌkæntiˈɒfətə, -oʊˈfaɪtə/ ( listen)) are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information.
How many species of liverworts are there?
9,000 species
liverwort, (division Marchantiophyta), any of more than 9,000 species of small nonvascular spore-producing plants. Liverworts are distributed worldwide, though most commonly in the tropics.
Which generation is the liverwort thallus?
Sexual (gametophyte) and asexual (sporophyte) generations characterize a liverwort life cycle. The gametophyte generation consists of the haploid thallus and is the dominant generation; it develops from a germinating spore.
What type of environment do liverworts thrive in and why?
They are non-vascular plants, and their lack of vascular tissue means they grow flat along the ground. It is also the main reason liverworts prefer moist environments. They can survive very harsh climates, but liverworts typically need to be near freshwater to survive.

Where is the Hudson Bay Lowland located?
Hudson Bay Lowland, a wetland area of Canada that covers about 320,000 square km (123,553 square miles) on the southern shores of Hudson Bay and James Bay, surrounded by the Canadian Shield. It falls largely in Ontario and Manitoba, with a small extension into Quebec. It is part of a sedimentary basin that extends beneath Hudson Bay and James Bay.
What animals live in the Hudson Bay Lowlands?
The wetlands provide important habitat for migratory birds including shorebirds (e.g., yellow rail) and waterfowl (e.g., snow geese). Large mammals include polar bear and wolverine. The Hudson Bay Lowlands approximately coincide with the Southern Hudson Bay Taiga Ecoregion of North America.
What are the characteristics of the Hudson Bay Lowlands?
Hudson Bay Lowlands. Plants from more temperate regions mix with arctic species. A majority of the wetland is peat bog, although salt marshes occur along the coast, and marshes and wet meadows occur along the major rivers. The wetlands provide important habitat for migratory birds including shorebirds (e.g., yellow rail) and waterfowl (e.g.,…
What are the major rivers in Hudson Bay?
Many wide and slow-moving rivers flow through this area toward the salt water of Hudson Bay: these include the Churchill, Nelson and Hayes in Manitoba, Severn, Fawn, Winisk, Asheweig, Ekwan, Attawapiskat, and Albany in Ontario, and the Harricana, Rupert and Eastmain in Quebec.
