Air pollution and climate change are threats to maintaining ecological health of protected areas. Protected Area managers require a meaningful way to measure impacts of these threats. Lichens provide a relevant, sensitive and measurable indicator for long-term monitoring. Hundreds of studies have linked lichen communities to air quality, and several long-term lichen monitoring programs in Europe and the US are using lichens to assess climate change. Other studies have shown strong correlations…

Macrolichen Indicators of Air Quality for Nova Scotia

Presentation and frequency of epiphytic macrolichens were measured along an air-quality gradient in Halifax City, NS, Canada and MDS analysis suggests an elevation gradient in Nova Scotia and this should be investigated with a further study.

Habitat associations and distribution model for Fuscopannaria leucosticta in Nova Scotia, Canada

This study elucidates locations as well as species-habitat relationships for F. leucosticta, providing land managers with baseline data that can aid in the discovery of additional populations and provide a better understanding of its ecological requirements which will support the development of sound conservation strategies for this rare lichen.

Regional Gradients in Lichen Communities of the Southeast United States

Epiphytic macrolichens were sampled in 203, 0.38 ha plots in the Southeast United States and gave a much clearer response to air pollution than either foliar symptoms or tree growth, and were one of the few ponents of terrestrial ecosystems to show a clear relationship to gradients of acidic deposition.

Long-Term Monitoring in the Netherlands Suggests that Lichens Respond to Global Warming

This is the first paper reporting long-term floristic changes for lichens that appear to be correlated significantly with increasing temperatures, indicating a recent and significant shift towards species preferring warm circumstances, independent from, and concurrent with changes due to nutrient availability.

MAPPING LICHEN DIVERSITY AS AN INDICATOR OF ENVIRONMENTAL QUALITY

In the last decades, several methods were proposed for assessing environmental quality — mainly air pollution — on the basis of lichen data (see chapter 4, this volume). At the end of the 80s the

HABITAT ASSOCIATIONS OF EPIPHYTIC LICHENS IN MANAGED AND UNMANAGED FOREST STANDS IN NOVA SCOTIA

Differences in lichen presence and abundance in natural and managed coniferous forests of Nova Scotia were studied and multiple linear regression was used to determine the forest structural features that best explained the abundance of each lichen taxon.

Nitrogen fixing lichens in forests of the southern Appalachian Mountains of North Carolina.

The abundance and species diversity of nitrogen fixing lichens were determined for several forests of the southern Appalachian Mountains of western North Carolina. Gray beech forests of wet,

Soil ecology of a lichen heath at Spitsbergen, Svalbard: effects of artificial removal of the lichen plant cover.

The Norwegian MAB project conducted research on the possible effects of overgrazing in winter pastures of the Spitsbergen reindeer, finding that heavy grazing may cause a decline in soil respiration and also a reduced abundance of microbial grazers such as the Collembola.

Mineral Cycling and Epiphytic Lichens: Implications at the Ecosystem Level

Abstract The nutrient contribution of lichens as litterfall in forests is discussed for a number of different ecosystems and it is hypothesized that lichens are important in capturing nutrients from

The Trade-off between Species Capture and Quantitative Accuracy in Ecological Inventory of Lichens and Bryophytes in Forests in Montana

To represent effectively both species diversity and cover, subsampling with small quadrats when vegetation is relatively dense or belt transects with sparse vegetation is recommended, which should be supplemented by a fixed-area reconnaissance for species not included in the quantitative sample.

Canopy Lichens with Blue‐Green Algae: A Nitrogen Source in a Colombian Rain Forest

The results reemphasize the importance of the epiphyte community in the canopy layer of the rain forest ecosystem and confirm the widespread presence of blue-green algae in rain forests of the American tropics.

The Influence of Epiphytic Lichens on the Nutrient Cycling of a Blue Oak Woodland

We evaluated the importance of epiphytic lichens in the nutrient cycling of a blue oak (Quercus douglasii) woodland in California. Each oak tree contained an average of 3.8 kg lichen biomass,
