summary EL 2007/6

Lichen seemingly one, but actually two

Ave Suija introduces lichenized fungi: some fungi combined with algae become lichens, while the same fungus without an alga exists as a normal fungus. Lichens have been considered as strange plants without leaves, trunks or roots. These exiting organisms have attracted scientists for centuries, but have deserved little attention in Estonian Nature. Systematically lichens belong to the Kingdom of Fungi. The cover story features these mysterious organisms thoroughly, explaining the symbiosis between fungi and algae and how the different types of partnerships are generated and developed.

Mires protect water

Hella Kink writes about a simple and well-known fact which, however, seems to be ignored by those who drain the mires. Mires function as generation and preservation areas for water, and their role lies also in maintaining natural water balance. Therefore, the drainage of mires affects environment on a larger scale. Mires should also be protected as natural monuments, and the author exemplifies this claim with numerous examples of different mires, starting from those located on karst areas to those on uplands and dunes. Currently, 116 mires have been listed as natural monuments in the Book of Estonian Primeval Nature.

The authors also describe the effect of mould fungi on the interiors of building and list the needs of such fungi.

Tiny human associates: Silverfish and others

The silverfish is a small, wingless insect from the insect order Thysanura. The species is estimated to have existed for 300 million years, originating in the Palaeozoic Era. The favourite food of silverfish is any matter that contains starch or polysaccharides. These include glue, book bindings, paper, photos, sugar, hair, and dandruff. Silverfish can also cause damage to books, tapestries, and textiles. Silverfish will commonly graze in and around showers, baths and sinks on the cellulose present in many shampoos, shaving foams and so on. Silverfish and other house-dwelling arthropods prefer high temperatures and high humidity.

European rarities in Estonia: the beetle Cucujus cinnaberinus

This pretty red beetle is rare everywhere in Europe, and there are only three known small populations identified in Estonia. The species prefers old-growth mixed forests with aspens, since its larvae are developed on dead or slightly decayed aspen trunks.
