Cryptogams of the Galapagos Islands (lichens, bryophytes, and fungi): New records, threats, and potential as bioindicators – a first evaluation

ثبت نشده
چکیده

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 association with algae. Their algae photosynthesize, supplying the fungus with nutrients, while the fungus provides the structural component. GALAPAGOS REPORT 2007-2008

Gastropods slow down succession and maintain diversity in cryptogam communities.

Herbivore effects on diversity and succession were often studied in plants, but not in cryptogams. Besides direct herbivore effects on cryptogams, we expected indirect effects by changes in competitive interactions among cryptogams. Therefore, we conducted a long-term gastropod exclusion experiment testing for grazing effects on epiphytic cryptogam communities. We estimated the grazing damage, ...

Comparative 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...

Epiphytes in wooded pastures: Isolation matters for lichen but not for bryophyte species richness

Sylvo-pastoral systems are species-rich man-made landscapes that are currently often severely threatened by abandonment or management intensification. At low tree densities, single trees in these systems represent habitat islands for epiphytic cryptogams. Here, we focused on sycamore maple (Acer pseudoplatanus) wooded pastures in the northern European Alps. We assessed per tree species richness...

A checklist of lichenized fungi of Kerman province, SE, Iran

lichenized mycota of the southern part of Iran including Kerman province has been poorly studied compared to the Northern Iranian provinces such as Azerbaijan, Golestan or Mazandaran. Here we present the first lichen checklist for Kerman province, which comprises 57 species in 30 genera and 14 families. For this purpose, we reviewed both old and recent literature, examined herbarium collections...

Biodiversity Value of Potential Forest Fertilisation Stands, as Assessed by Red-Listed and ‘Signal’ Bryophytes and Lichens

In Sweden ca. 20 000 ha forestland is fertilised each year. By using red-listed and ‘signal’ bryophytes and lichens as indicators, we investigated whether forest stands planned for fertilisation have a biodiversity value, and thus if restrictions due to conservation aspects are motivated. Species occurrences were registered in detailed line-transect analysis, with a record size of 10 × 10 m, in...
