“…Previous work on North American quaking aspen (Populus tremuloides Michx.) tested whether portions of trees with smooth versus rough or scarred bark would attract more species and found stark contrast in favor of scarred trunk sections [11]. We note here that Pisonia has smooth bark which may be deleterious to lichen colonization and may be partly responsible for undefined factors reflected in axis 2 of our ordination.…”

“…The bulk of all Pisonia forest coverage in Australia, however, is found in the southernmost island groups [5]. Similarly, we may consider tracking changes in vegetative diversity using successional gradients (based on dominant tree cover) as a surrogate for time [11]. Relationships between biodiversity and Pisonia height, time since disturbance, relative amount of coverage, presence of other tree species, plus salt, light, and wind tolerance have been posited by others [7,28].…”

“…We are unaware of applications of this bioindicator approach in coral cay ecosytems though it is accepted practice elsewhere [9]. Previous studies have linked lichen communities to forest cover change [10,11], wildlife concerns [12], and landscape-level biological diversity [13,14]. Forest systems with a wider range of tree species (i.e., those with diverse bark chemistries and textures) often support broader lichen floras [11,15,16].…”

Forest systems with a wider range of tree species (i.e., those with diverse bark chemistries and textures) often support broader lichen floras [11,15,16]. In Australia, epiphytic lichens were shown to be particularly sensitive to forest disturbance among a wide suite of indicators [17].…”

Coral islands around the world are threatened by changing climates. Rising seas, drought, and increased tropical storms are already impacting island ecosystems. We aim to better understand lichen community ecology of coral island forests. We used an epiphytic lichen community survey to gauge Pisonia (Pisonia grandis R.BR.), which dominates forest conditions on Heron Island, Australia. Nine survey plots were sampled for lichen species presence and abundance, all tree diameters and species, GPS location, distance to forest-beach edge, and dominant forest type. Results found only six unique lichens and two lichen associates. A Multi-Response Permutation Procedures (MRPP) test found statistically distinct lichen communities among forest types. The greatest group differences were between interior Pisonia and perimeter forest types. Ordinations were performed to further understand causes for distinctions in lichen communities. Significant explanatory gradients were distance to forest edge, tree density (shading), and Pisonia basal area. Each of these variables was negatively correlated with lichen diversity and abundance, suggesting that interior, successionally advanced, Pisonia forests support fewer lichens. OPEN ACCESSForests 2015, 6 1558Island edge and presumably younger forests-often those with greater tree diversity and sunlight penetration-supported the highest lichen diversity. Heron Island's Pisonia-dominated forests support low lichen diversity which mirrors overall biodiversity patterns. Lichen biomonitoring may provide a valuable indicator for assessing island ecosystems for conservation purposes regionally.

“…Some components of cryptogamic communities have been shown to be particularly sensitive to climatic shifts (McCune 2000;Jägerbrand et al 2006;Cornelissen et al 2001;Bjerke 2011), and these communities, due to their sensitivity, may play an important role in monitoring the potential impacts of climate change. Although lichens are well-known indicators of air quality, recent studies indicate that they may also be useful in assessing ecological shifts related to climate change (Cornelissen et al 2001;Rogers and Ryel 2008;Bjerke 2011).…”
