Introduction
Marjorie D. delos Angeles is currently an Assistant Professor 7 of the Plant Biology Division, Institute of Biological Sciences, UPLB. She has written publications in relation to physiological responses of plants in heavy metal contaminated areas as well as publications in relation to pteridophyte diversity of Mt. Makiling. She is an aspiring botanical artist. She believes that botanical illustration is an avenue to peak interest, and further appreciate the beauty and importance of plants.

The extensive forests over limestone of the Samar Island Natural Park (SINP) on Samar Island, Philippines harbour a rich variety of unique species. In this contribution, we describe and illustrate a new Loranthaceous mistletoe, endemic to Samar Island named Decaisnina tomentosa , representing the 12th member of the genus reported to the Philippines...

Leaf size is one of the plant functional traits that can explain ecosystem function. This study identified the leaf size classes of trees in the forest over limestone ecosystems of Samar Island Natural Park, Samar Island, Philippines. One-sided surface leaf areas of voucher specimens from 18 sites in SINP were measured and data obtained were calcul...

This study provides a checklist of the vascular flora and terrestrial vertebrate fauna in forests over limestone in Paranas, Samar Island Natural Park (SINP), Philippines, a UNESCO World Natural Heritage Site nominee. Nine 20x20m plots and 18 line transects were established for the floral inventory. The faunal assessment was conducted in transects...
Article
This study presents the first checklist of the lesser known terrestrial biodiversity in forests over limestone karst of Calicoan Island in Guiuan Marine Reserve Protected Landscape and Seascape, Guiuan, Eastern Samar, Philippines. Plants and terrestrial vertebrate species in nine 20x20 m plots and 18 line transects were recorded and identified. A t...

Changes are evident in fern species richness, composition, and abundance as a result of environmental changes caused by forest conversion to various land use types. This study identified fern species and described its distribution pattern with reference to ecological parameters obtained from various land use types across the northeastern slope of M...

A comprehensive review of literature was carried out to determine the status of plant and animal diversity on forests over limestone in Southeast Asia (SEA), particularly in the Philippines. Angiosperm records are available in Peninsular Malaysia (1216 spp.); West Java and Seram Indonesia (101 and 149 spp., respectively); Laos (135 spp.); Thailand...

Mt. Makiling of Luzon Island, Philippines is home to many living organisms including ferns and fern allies which are one of the important understory vegetation in many forest communities and having various economic uses like food, medicine and ornamentation. This study identified fern species found in various land use types across the northeastern...

This study surveyed the different medicinal plants found in Mount Ma-nunggal, Bgy. Sunog, Balamban, Cebu, Philippines. A series of informal interviews, semi structured questionnaire, and discussions among the key informants was employed to acquire pertinent data. A total of 20 species belonging to 20 genera from 18 families were recorded to be pres...
Article
Fern zonation studies provides information regarding fern composition along the altitudinal gradient of the mountain. In addition, it also recognizes ferns as important bio-indicators for such studies. Fern zonation patterns as well species composition along the northeastern slope of Mt. Makiling during the wet season were determined. The plot t¬ec...

This study aims to determine leaf morphological and anatomical alterations of Mangifera indica L. and Ficus benjamina L. induced by air pollutants in a polluted area (Jones Avenue) and a non-polluted area (Bgy. Malubog) at Cebu City. Free hand sections were done to observe changes in leaf structure. Leaf sections were observed using a stereomicrosc...

Studies regarding pteridophyte distribution on Mt. Makiling is scarce. A continuous documentation regarding this floral group, with emphasis on distribution, will contribute to the current listings and may contribute to the development of a conservation strategy to preserve the fern flora of Mt. Makiling. The plot technique method was employed alon...

CONserve-KAIGANGAN is a research program led by the University of the Philippines Los Baños, consistent with its mandate to safeguard biodiversity and ecosystems, among others, in addition to agriculture and forestry. Funded by the Department of Science and Technology (DOST) and the Philippine Council for Agriculture, Aquaticand Natural Resources Research and Development (PCAARRD), this program aims to assess and conserve the biodiversity in kaigangan (local term for forests over limestone) towards its sustainable management in Samar Island, Philippines. CONserve-KAIGANGAN is mainly composed of researchers from UPLB Institute of Biological Sciences (Center of Excellence for Biology awarded by CHED and UP), UPLB College of Forestry and Natural Resources (Center of Excellence for Forestry), UP Manila (Center of Excellence for Health Sciences) and a leading state institute in Samar, the Samar State University.
