Arctic biodiversity is structured by a range of environmental factors. To understand which environmental factors that are decisive to the species composition in an area,
Glaciation have shaped biodiversity through time, but glaciations also greatly affects habitat and ecosystem development within landscapes. Mountain slopes above the marine limit are covered
Compared to Bacteria and Eukaryotes, Archaean diversity, physiology and ecology is still very little explored. Many Archaea are extremophiles – living in extreme environments –
There has recently been published a summary of the available knowledge of freshwater systems in Svalbard. With permission from the authors (John E. Brittain, Ann
Arctic regions are characterized by long cold winters and short cool summers. In order to establish invertebrates require more than to be able to tolerate
Fungi are heterotrophic organisms feeding by osmotrophy. Their ecology can be divided into saprotrophs, parasites and mutualists. However, transitions exist between all these groups. Most
Bryophytes are found throughout the world from the harsh environments of Antarctica to the lush conditions of the tropical rainforests. Despite their small size, they
Bacteria are the major drivers of the Earths biogeochemical cycles, and therefore very important components of the ecosystems. There are estimations showing that more than
Bryophytes have many important ecosystem functions in the Arctic. These include: Regulation of hydrology In many habitats, bryophytes control soil and vegetation hydrology (Beringer et
Many bryophyte species are very sensitive to certain environmental conditions – both naturally occurring and imposed by anthropogenic activity. Bryophytes are used as indicators and
Saprotrophic fungi degrade dead organisms or their remains, such as litter or dung. Depending on their mode of breaking down cellulose or lignin, we recognise
Bryophytes are the second most diverse group among land plants after the flowering plants (Magnoliophyta, ~350 000 described species; Glime 2007). Defining the number of species of
History The Pleistocene is the world’s recent period of repeated glaciations between 2.5 million to 11700 years ago. More than 20 cycles of glaciation occurred
Evolutionary origin Bryophytes belong to the embryophytes, which include all land plants. Evidence from structural, biochemical, and molecular data supports the view that bryophytes and all
Since the turn of the previous century, when Arctic explorers began to return samples of microbes for culture and study, our understanding of the microbiology
Parasitic and pathogenic fungi obtain their nutrition from other living organisms, and have a negative effect upon the individuals – hosts – they are parasites
