“…As noted earlier, the colonization, survival and succession of epiphytes in urban forests are controlled by vegetation patterns [27], environmental factors [28][29][30] and substrate suitability [31]. The rate of colonization is usually low [39], and urban forests may not have the same epiphyte assemblage as natural forest [40].…”

The spatial distribution of corticolous lichens on the iconic New Zealand pōhutukawa (Metrosideros excelsa) tree was investigated from a survey of urban parks and forests across the city of Auckland in the North Island of New Zealand. Lichens were identified from ten randomly selected trees at 20 sampling sites, with 10 sites classified as coastal and another 10 as inland sites. Lichen data were correlated with distance from sea, distance from major roads, distance from native forests, mean tree DBH (diameter at breast height) and the seven-year average of measured NO2 over the area. A total of 33 lichen species were found with coastal sites harboring significantly higher average lichen species per tree as well as higher site species richness. We found mild hotspots in two sites for average lichen species per tree and another two separate sites for species richness, with all hotspots at the coast. A positive correlation between lichen species richness and DBH was found. Sites in coastal locations were more similar to each other in terms of lichen community composition than they were to adjacent inland sites and some species were only found at coastal sites. The average number of lichen species per tree was negatively correlated with distance from the coast, suggesting that the characteristic lichen flora found on pōhutukawa may be reliant on coastal microclimates. There were no correlations with distance from major roads, and a slight positive correlation between NO2 levels and average lichen species per tree.

“…It is the total effect of area and habitat that determines the biodiversity of the region. Therefore, biodiversity could be improved by increasing the choros value via the construction of diverse habitat types, which was especially important for bryophytes because the habitat types suitable for bryophytes are relatively and easily constructed or formed by human interventions [ 59 , 60 , 61 , 62 , 63 ].…”

Aim: To clarify whether (1) there are thresholds in the species–area–habitat relationship for bryophytes and potential mechanisms, (2) such thresholds vary among different bryophyte groups, and (3) choros is better than area or habitat alone in the prediction of SR. Location: Islands in central and southern Zhejiang, China. Methods: We investigated the species richness (SR) of five bryophyte groups (total bryophytes, total mosses, liverworts, acrocarpous mosses, and pleurocarpous mosses) and habitat types on 66 islands. By using four threshold models, the logarithmic and the power models, we quantified their SR–choros relationships (SKRs), species–area relationships (SARs), and species–habitat relationships (SHRs). We also conducted path analyses to detect the direct effects of area per se and habitat per se on the SR. Results: The AICc values of the SKR models were overall smaller than those of the respective SAR and SHR models. The left-horizontal two-threshold model was best for the SKRs. A phenomenon (the small-choros effect, SCE) in which SR independently varied choros below a given threshold was detected. The SCE thresholds were smaller in mosses than in liverworts and in acrocarpous mosses than in pleurocarpous mosses. No direct and positive effects of habitat per se on the SR were detected below choros thresholds for all five groups. Main conclusions: There were two thresholds and SCEs in the SKRs of all five bryophyte groups. The SCEs likely resulted from the elimination of the direct and positive effects of habitat diversity on the SR of the bryophytes on small choros islands. The SCE thresholds were high for species groups sensitive to environments. Choros was better than area or habitat alone in determining the SR of the bryophytes on continental islands.

“…Medan, as the capital of the North Sumatra province, has several city parks with various species of trees, which are mostly overgrown with bryophytes. These trees provide potential alternative habitats for epiphytic bryophytes from the high rate of forest destruction and enhanced conservation of urban biodiversity (Zhao et al 2021;Zołnierz et al 2022). The species of trees favored by the bryophytes as hosts are also unknown, which is important for selecting species as good epiphytic hosts.…”

Abstract. Siregar ES, Pasaribu N, Lubis AF. 2023. Diversity of epiphytic bryophytes in Medan City Parks, North Sumatra, Indonesia and its potential as lead (Pb) bio-accumulators. Biodiversitas 24: 3214-3221. The information on the diversity of epiphytic bryophytes in the metropolitan area, particularly Medan City, North Sumatra, Indonesia has been limited. Therefore, this study aimed to conduct an inventory of the diversity of epiphytic bryophytes in Medan City parks as well as to assess their potential as lead (Pb) bioaccumulators. Three sampling sites, namely Ahmad Yani Park, Beringin Park, and Medan Zoo, were selected based on their pollution levels from high to low, respectively. Five plots with dimensions of 25×25 m were placed at each site and five representative host trees were selected in each plot. Lead (Pb) bioaccumulation of bryophyte samples is determined using the atomic absorption spectroscopy (AAS) method at the Plant Research Center Laboratory, Medan. The Pb-bioaccumulation capacity of each species from different sites was compared through two-way ANOVA. The results showed eight species, namely four liverworts (Marchantiophyta): Cololejeunea lanciloba Steph., Lejeunea cocoes Mitt., Lopholejeunea eulopha (Taylor) Schiffn., and Lopholejeunea subfusca (Nees) Schiffn., as well as 4 Mosses (Bryophyta): Calymperes tenerum C.Müller, Meiothecium microcarpum Mitten, Octoblepharum albidum Hedwig and Vesicularia dubyana Brotherus. Vesicularia dubyana was the dominant species at Beringin Park and Medan Zoo, while C. tenerum was dominant at Ahmad Yani Park. The biodiversity of epiphytic bryophytes in this study was categorized as moderate level (1?H’?3). The highest Important Values Index (IVI) of epiphytic bryophytes in this study was obtained for V. dubyana at 131.80. The highest Pb bioaccumulation was observed in O. albidum at 87.5 mg/kg, followed by V. dubyana at 66.6 mg/kg. This study provided information on the ecological contribution of epiphytic bryophytes as Pb bioaccumulators in urban areas. Vesicularia dubyana and O. albidum can be recommended as biomonitoring agents in the future.
