Identification of Pteridophyte Species in Kalikasan Park, Daraga, Albay, Philippines
BU R&D Journal, 2018
Pteridophytes are vascular, spore-bearing plants, which are composed of ferns and their allies. Although commonly used in horticulture, it is also known to have medicinal values. This study identified the fern species present in Kalikasan Park, a forest fragment adjacent to Bicol University main campus in Legazpi City, Philippines. The Line Transect Method was employed wherein a 50 m transect line with an alternating 5x5 meter plot was set in the two sampling sites. A total of 14 fern species belonging to nine families and nine genera were found in the two sampling sites. Shannon's Index of Diversity (H') value of 2.08 and an Evenness (E) value of 0.8354 were recorded in sampling station 2. The anthropogenic disturbance and infrastructure expansion without clear-cut boundaries is a challenge to the fern population in the area. It is recommended that a comprehensive plan to safeguard the biodiversity of Kalikasan Park and of the university's main campus be put in place.

Ferns (Pteridophyta) are free-sporing vascular plants with a unique life cycle with free-living gametophyte and sporophyte phases. The fern species has nearly 90% of the extant diversity, it was the first higher-level of pteridophyte classification in the world. This study aimed to assess and identify the different species composition and diversity variation of ferns found in the lower elevations at the primary forest in Barangay San Rafael, Prosperidad Agusan del Sur, Philippines. Moreover, the researchers were used the quadrat sampling method as one of the best and classic tools utilized in ecology especially determining the diversity of a specific sampling sites. Also, the study used Shannon's diversity index method in determining the biological diversity of plant species particularly ferns (Pteridophyta). The total number of ferns that was primarily collected at Barangay San Rafael, Prosperidad, Agusan del Sur are nine (9) species from 5 families. The researchers linked the gathered data of ferns (Pteridophyta) by calculating its diversity index of 1.864, were showed medium diversity because most likely the pteridophyte communities were similar in all transects. Thus, the study area has medium species diversity results in a more complex, stable, and productive ecosystem as could be observed in San Rafael Forest. The results show that the growth and distribution of ferns was inhibited significantly by the environment properties.

Three forest areas of Cebu Island, Philippines were recognized as Key Biodiversity Areas (KBAs) by Department of Environment and Natural Resources [DENR], Philippines based on the criteria of vulnerability and irreplaceability, namely Nug-as of Alcoy, Palinpinon Range of Dalaguete, and Mt. Lantoy of Argao. The study aimed to assess the composition, diversity, and distribution of ferns in the aforementioned KBA's. Quadrat at 20 m x 20 m was established within the 2000 m transect line at an interval of 200 m. Result showed a total of 50 species, categorized into 15 families and 29 genera for 30 quadrats. Twelve species were considered as new records on Cebu. Thirteen species were recorded in both Mt. Lantoy and Nug-as forest KBA's, but absent in Palinpinon range. While 6 species were recorded as unique to Nug-as forest. Nug-as forest and Mt. Lantoy showed a relative value of very high species diversity. Nug-as forest and Mt. Lantoy KBA forming into one cluster and Palinpinon range proved to have a distinct fern species composition, and form another cluster. Local government units (LGU) in every KBA need to recognize the necessity of biodiversity information in their localities that would facilitate information sharing and awareness, hence enhancing protection and conservation of unique biodiversity, since they are at the forefront of local action.

Biodiversity of small islands, particularly in tropical region, always encourages scientific curiosity. Such curiosity is much greater when the small island of interest has been through various land use changes, such as in Karimun Besar Island. This island is one of thousand islands in Riau Islands Province, Indonesia and poses different land uses. However, studies on the biodiversity of flora in this island have not been recorded, including for pteridophyte or fern members. This study aimed to examine the diversity, floristic structure and composition of pteridophyte at six different study sites in Karimun Besar Island representing varying habitat conditions (i.e., primary forest, secondary forest, rubber plantation, road side, coastal area and mined land. The sampling was collected by using transect method to measure density, dominance and frequency. A total of 32 species of pteridophytes were recorded from the six study sites that belong to two divisions, Polypodiophyta (31 species) and Lycophyta (1 species). The number of species of pteridophyte varied across the six habitats. The highest number of species (21) was found in primary forest, while the lowest (9 species) was found in rubber plantation. The dominant species for each study site were Taenitis blechnoides (Pteridaceae) (rubber plantation), Dicranopteris linearis (Gleicheniaceae) (secondary forest), Sticherus truncates (Gleicheniaceae) (primary forest), Pteridium caudatum (Dennstaedtiaceae) (road side), Achrosticum aureum (Pteridaceae) (coastal area) and Nephrolepis hirsutula (Nephrolepidaceae) (mined land). The result of this study provides the first data of fern in Karimun Besar Island that support pivotal information on the biodiversity of small islands in tropical region.
DIVERSITY AND DISTRIBUTION PATTERN OF FERNS AT BUKIT LARUT
Journal of Research in Forestry, Wildlife & Environment, 2021
In this preliminary study, the ferns diversity and richness were assessed at Bukit Larut, Taiping, Malaysia. This was done to understand the pattern of distribution of the ferns and their conservation statuses. Plots of size 10 x 10 m were established at different elevations along the hill using a preferential Random Sampling method and ensuring a minimum distance of 20 m between each plot. Although there were variations in the ferns diversity and richness with regards to the different elevations studied, the base of the hill was still more diverse in ferns (Shannon index = 1.28 and Margelef index = 1.27). Fifteen ferns belonging to 10 families were identified in all the sampled plots. Dicranopteris linearis was observed to be weedy and more abundant. Terrestrial ferns were reported to be the most common and abundant in this hill forest. This is an indication of less-disturbed nature of the forest.

The line intercept method was used to determine fern patch structure and species diversity along the altitudinal gradient of the northeastern slope of Mt. Banahaw de Lucban, Quezon, Luzon Island, Philippines. A total of 93 species under 47 genera and 24 families were found in the study area, eight of which are Philippine endemics. The most represented families are Polypodiaceae (11 spp.), Hymenophyllaceae (11 spp.) and Aspleniaceae (9 spp.) while the most represented genera are Asplenium (9 spp.), Lycopodium (5 spp.) and Selaginella (5 spp.). Species diversity gradually increased with elevation, reaching a maximum at 814 – 886 m above sea level. Based on the result of stepwise multiple regression analysis, the slope was linearly related to species diversity, explaining 16% of the variation in H' [H' = 1.4928 + 0.0092(Slope); r = 0.3995]. On the other hand, there was no direct relationship between species cover and altitude. Majority of the fern patches sheltered all the pteridophyte height classes designated in this study. At least 85% of the pteridophyte species were preferential. Selaginella delicatula (Desv.) Alston, Selaginella cumingiana Spring, Cyathea callosa Christ, Sphaerostephanos hirsutus (Kunze ex Mett.) Hollt. var. hirsutus, Cephalomanes apiifolia (C. Pres.) K. Iwats and Cyathea philippinensis Bak. were the most widely adapted fern species along the slope.
Species richness of terrestrial ferns and lycophytes may indicate forest habitat quality, as analyzed for a tropical lowland of Mig Camp Resort in Katipunan. Terrestrial fern species can serve as indicators of disturbance or forest quality as many species show clear habitat differentiation with regard to light conditions and humidity. This research aims to assess forest habitat quality of Mig Camp Resort terrestrial pteridophyte species by grouping ferns and lycophytes according to their ecological requirements into 'forest species' and 'non-forest species'. Results showed that there are 21 species in this area that are categorized as forest species indicating that this primary forest is not yet totally unconserved. In places where primary forest is still present, priority should be given for the conservation of the remaining primary forest patches.
Phenotypic Variations of Extant Ferns in Mt. Hamiguitan Range, Mindanao Island, Philippines
World Applied Sciences …, 2011
In situ morphological characterization using 23 qualitative and 21 quantitative morphological traits, subjected to combined Principal Component Analysis (PCA) and cluster analysis, was carried out to determine the phenotypic relationships/diversity of 55 fern species thriving in Mt. Hamiguitan, Philippines and identify the underlying causes of observed phenotypic variability. PCA reduced the 44 characters into 12 principal components which cumulatively explained 79.9% of total variance and clustered the ferns into groups according to discriminant traits (length of lateral pinnae, width of blade, receptacle position and true indusium). Cluster analysis using UPGMA and UPGMC revealed similar groupings and trends. Both trees showed the divergence of the 3 fern species (Sticherus hirtus Copel, Dipteris conjugata and Cyathea sp) and the morphological homogeneity of the rest. Moreover, UPGMA outperformed UPGMC in terms of classifying the fern species into functional groups on the basis of dissimilarity. This study, predating molecular diversity analysis, has demonstrated the effectiveness of this low-level taxonomic tool when used with powerful statistical techniques.
