“…Our study might have created a similar effect to these disturbances (animal activity, tree fall gaps; [16]) and enabled the moss module development. In this subtropical moist forest, there are about 50 species of moss [24]; the moss species found (11 species) only represent 22% of local flora. Six species are acrocarpic and the other four are pleurocarpic.…”

A bryophyte propagule bank serves as a source for population maintenance and survival, and many factors can influence these propagules' germination. However, it is unknown how soil depths affect propagules banks, their diversity and abundance overtime in a Neotropical forest. To understand such a paradigm, soil samples were obtained from different depths (0 -5 cm, 5 -10 cm, and 10 -15 cm) at Guajataca State Forest, Puerto Rico; then, they were transferred to the laboratory, cultured, and the amount of gametophytes from propagules present over a seven-month period were measured. Forest soil depth did affect the density of gametophytes. Gametophytes densities augmented overtime for almost all species. Two species mainly influenced the propagule production over time. Also, propagules can have a long-term germination potential for some species.

“…The overall species richness in these novel forests is higher than that of some sinkholes that are considered centers of bryophyte diversity (Reyes‐Colón & Sastre‐De Jesús ). The nine S. campanulata study forests jointly rank seventh (from a list of 13 Commonwealth Forests) in moss diversity below those of the Guajataca, Carite, and Guilarte nature reserves (Pérez & Sastre‐De Jesús ). The overall moss species composition of S. campanulata patches is similar to older native forest patches (Guajataca and Río Abajo) in the karst belt, this area being considered both the most intact forest cover and the least fragmented habitat left in Puerto Rico (Mujica‐Ortiz & Day ).…”

“…As liverworts species are little known in Puerto Rico, we compared only moss species richness and composition of the S. campanulata forests with mosses species lists and distribution published by the following authors: Sastre‐De Jesús and Buck (), Reyes‐Colón and Sastre‐De Jesús (), and Pérez and Sastre‐De Jesús (). A presence/absence matrix was used to compare species composition of S. campanulata forest patches with Commonwealth Forests and Federal Forest Reserve in Puerto Rico (Fig.…”

“…The overall species richness in these novel forests is higher than that of some sinkholes that are considered centers of bryophyte diversity (Reyes-Colón & Sastre-De Jesús 2000). The nine S. campanulata study forests jointly rank seventh (from a list of 13 Commonwealth Forests) in moss diversity below those of the Guajataca, Carite, and Guilarte nature reserves (Pérez & Sastre-De Jesús 2009 ). If we compare the S. campanulata patches with forests on karst topography, we found that the patches shared more species with moist sites (sinkholes, SiKS) than dry areas (exposed stack hills, MKS; Fig.…”

Bryophyte Species Diversity in Secondary Forests Dominated by the Introduced Species Spathodea campanulata Beauv. in Puerto Rico

et al. 2012

The introduced tree species Spathodea campanulata (Bignoniaceae) forms novel forests in Puerto Rico, these having emerged after the abandonment of fields in the mid‐20th century and resulting in forests with a new species composition. We assessed bryophyte species richness in these novel forests and sought correlations with geological substrate, past land use, forest edge and patch area, forest structure, elevation, microhabitat diversity, tree species richness, and microclimatic conditions. Transects were established (edge and forest interior) in nine moist forest patches dominated by Spathodea in north‐central Puerto Rico. These Spathodea forest patches ranged from 0.6 to 9 ha. ANOVA, Chi‐square, correlation, and cluster analyses were used in data analyses. We found 57 bryophyte species. There was a significant difference in bryophyte richness among patches. Those on karst exhibited highest bryophyte richness due to microhabitat diversity, past land use, and shorter hydroperiods. Alluvial sites scored lowest in bryophyte species richness, and forest structure was important for bryophyte communities on these sites. Significant differences in temperature, relative humidity, and light intensity were observed between edge and forest interior. These appeared important for establishing bryophyte species cover but not richness and composition. Microhabitat diversity, patch area, and forest age were more related to bryophyte species richness than elevation, exposed edge, and tree species richness, regardless of geologic substrate. Collectively, Spathodea patches were similar to mature forests on the Island with respect to bryophyte species richness and composition. Novel Spathodea forests have conservation value due to their habitat suitability for bryophyte communities.
