Cryptogams of the Galapagos Islands (lichens, bryophytes, and fungi): New records, threats, and potential as bioindicators – a first evaluation
Lichens, fungi, and bryophytes are frequently referred to as lower plants, non-vascular plants, or cryptogams. All terms are partially incorrect but used for convenience. Strictly speaking only bryophytes are plants. Although lacking conductive tissues, they are photosynthetic. Fungi are not photosynthetic, typically penetrating their substrate as threads of cells. Lichens are fungi in close as...
متن کاملMorphological, photosynthetic and water relations traits underpin the contrasting success of two tropical lichen groups at the interior and edge of forest fragments
BACKGROUND AND AIMS Forest edges created by fragmentation strongly affect the abiotic and biotic environment. A rarely studied consequence is the resulting impact on non-vascular plants such as poikilohydric lichens, known to be highly sensitive to changes in the microenvironment. We evaluated the impact of forest edge and forest interior on the distribution of two groups of crustose lichens ch...
متن کاملComparative cryptogam ecology: a review of bryophyte and lichen traits that drive biogeochemistry.
BACKGROUND Recent decades have seen a major surge in the study of interspecific variation in functional traits in comparative plant ecology, as a tool to understanding and predicting ecosystem functions and their responses to environmental change. However, this research has been biased almost exclusively towards vascular plants. Very little is known about the role and applicability of functiona...
متن کامل5 Lichens as bioindicators of air pollution
Lichens are considered the result of a symbiotic association of a fungus and an alga. More precisely the term “alga” indicates either a Cyanobacteriae or a Chlorophyceae; the fungus is usually an Ascomycetes, although on rare occasions it may be either a Basidiomycetes or a Phycomycetes. In this association, the alga is the part that is occupied with the formation of nutrients, since it contain...
متن کاملAn experimental comparison of chemical traits and litter decomposition rates in a diverse range of subarctic bryophyte, lichen and vascular plant species
1. Climate change in the subarctic is expected to influence vegetation composition, specifically bryophyte and lichen communities, thereby modifying litter decomposition rates and carbon (C) dynamics of these systems with possible feedbacks to climate. 2. In a two-year experiment, we investigated decomposition rates and chemical traits of 27 bryophytes, 17 lichens and 5 vascular plants in litte...
