The study investigated the leaf architecture and petiole anatomy of eight Dipterocarpus (Dipterocarpaceae) species growing in Mount Makiling Forest Reserve (MMFR) in the Philippines to delineate the species, especially during their non-flowering phase. Leaf and petiole samples from MMFR were examined following the manual on leaf architecture studies. Freehand technique was used to examine the stomata and petiole characters. A UPGMA phenogram was then generated to determine the relationships among Dipterocarpus species using 26 leaf and petiole characters. The most useful characters to delineate Dipterocarpus species are the presence of trichomes, the arrangement of vascular bundles (medullary and outer vascular bundles), areolation, fimbrial vein, and leaf size. Other characters viz., the laminar ratio, blade class, laminar shape, base shape, margin type, and intersecondary, and layers and shape of parenchyma and collenchyma cells were useful as unifying characters. Therefore, certain characters of the leaf architecture and petiole anatomy may be used as taxonomic markers to delineate and correlate the Dipterocarpus species in the Philippines particularly during the nonflowering phase of the species. However, further investigations using samples from the wild populations of the species and molecular techniques may be done to elucidate the taxonomic use of the characters presented in this study.

Forest and the goods and services they provide are essential for human livelihood and wellbeing. An assessment on the likely impact of  deforestation on NTFPs along gender line is therefore imperative for effective adaptations for NTFPs collectors. The study examined the adaptive strategies to deforestation stress employed among NTFPs collectors across gender line in Oluwa Forest Reserve area of Ondo State, Nigeria. Multistage sampling technique was used to select respondents for the study. Data were collected with the aid of well-structured interview schedule on 181 NTFPs collectors (94 males and 87 females) and analysed using descriptive statistics and inferential statistics. The data targeted socio-economic characteristics, level of availability of (NTFPs) in the mist of deforestation currently and 30 years ago as well as adaptive strategiesemployed by the respondents in the study area. Findings revealed that average age of male and female respondents were 48 and 43 years, respectively. Bitter Kola, Kola Nut, Mango and Walnut were NTFPs available in abundant 30 years ago. In recent years, the study discovered that only Mango and Walnut were available in excess despite persistent deforestation in the study area. Deforestation impacted more on female collectors compared to their men counterpart. The finding also shows that female collectors employed more of domesticated NTFPs and indigenous protection methods as adaptive strategies against deforestation. The study recommended training on scientific domesticated system of planting (NTFPs) for both male and female NTFPs collectors as well as community policing to cope against deforestation in the study area.

Abstract A number of studies had been conducted on rat species diversity in the Philippines, however, there is a dearth of information on the extent of Angiostrongylus spp. infection in various ecological niches. Collection of non-native rat samples occurred in various sampling sites categorized as residential, agricultural and agro-forest in Philippine Mount Makiling Forest Reserve (MMFR) and its adjacent areas . Three species of non-native rats were captured including Rattus tanezumi, Rattus norvegicus and Rattus exulans. Of the total 90 non-native rats collected, 24.4% were found infected with Angiostrongylus cantonensis. Statistical analysis showed significant difference among rat species with highest prevalence observed in R. exulans (42.9%) followed by R. tanezumi (29.8%) and R. norvegicus (7.7%) (P = 0.047). Angiostrongylus cantonensis infection was significantly higher in adults (29.4%) than in juvenile rats (9.1%) (P = 0.050). However, results showed no significant difference in A. cantonensis infection between male (43.3%) and female (18.3%) rats and between wet (31.6%) and dry seasons (19.2%) (P > 0.05). Moreover, this study also revealed that rats from agricultural and agro-forest areas showed significantly higher prevalence than residential areas. With urbanization and the everchanging landscape of MMFR watersheds and buffer zones, zoonotic transmission can pose health threats to the local people.

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 Mt. Makiling Forest Reserve, Los Baños, Philippines. The plot technique was employed using a 20x20 meter quadrat. Three 5x2 subquadrats were randomly distributed within the established quadrat. Cluster and ordination analysis were used and edaphic factors were analyzed. Fern specimens were identified (sensu PPG) and measured. Samples were collected for herbarium vouchers and were deposited at the Plant Biology Division Herbarium, University of the Philippines Los Baños (PBDH). Cluster analysis revealed six land use types: buffer, agroforest, agri-farm, roadside, mahogany, and forest. Twenty-nine (29) fern species belonging to 23 genera from 14 families were recorded across the different land use types. Among the land use types, the forest had the highest fern species richness (13) and the agri-farm and Mahogany had the least (6). Canonical correspondence analysis indicated that moisture, OM, pH, and CEC were significant explanatory drivers of fern distribution especially in the Mahogany and Agroforest land use type. Understanding the fern community patterns and edaphic factors in Mt. Makiling would aid in its conservation planning.

Makiling Forest Reserve, Laguna, Philippines: with floristic update on roadside samples in Makiling Botanic Gardens(MBG). Biodiversitas 19: 1579-1585. The Mt. Makiling Forest Reserve (MMFR) stands as a highly biodiverse habitat and the onlyintact natural forest near Metro Manila, the Philippines. It is one of the 18 key centers of plant biodiversity and 32 key ecotourism sitesin the Philippines. In monitoring the implementation plans for protecting MMFR, the information pertaining to the mushroombiodiversity across decades is important. Therefore, we aim to study mushroom as an indicator for biodiversity since there has beenstudies in the past 30 years on the macrofungi of MMFR which we summarized here along with ours. Sampling was done in August2017 based on the transect line of 1000 m along roadsides of Makiling Botanic Gardens (MBG). The distribution of the sampling unitswas carried-out using random and stratified sampling. Our study describes 21 macrofungal taxa collected from MMFR. Of these, 20taxa belong to Basidiomycota and only one belongs to Ascomycota. Polyporaceae was found as the most dominant macrofungi family(24%). There were six (6) species that are medicinal, and no poisonous species noted. There are eleven (11) species in this study whichare unique records compared with previous studies done in the macrofungi of MMFR. This is the first study done comparing mushroomacross 30 years on a reserved area. Information on these macrofungal flora across time serves as a reference for the currently existingconservation efforts and implementation of biodiversity-related policies in MMFR.

AbstractThe Ryukyu flying fox (Pteropus dasymallus) is distributed throughout the island chain spanning across southern Japan, Taiwan, and possibly the Philippines. Although P. dasymallus is listed as VU (vulnerable) in the IUCN Red List, only few genetic works have been conducted to support its conservation. In this study we analyzed 19 markers (mtDNA haplotypes and 18 microsatellite markers) to evaluate genetic diversity and investigate the genetic structure of this species.mtDNA analysis was conducted with 142 DNA remote samples, mostly from feces, and wing tissues collected on eight islands (Miyako, Ishigaki, Kohama, Kuroshima, Hateruma, Taketomi, Iriomote, Yonaguni). 39 haplotypes were identified in 526bp of the control region, and haplotype network showed no clear genetic structure.Microsatellite analysis was also conducted with 155 samples collected on six islands (Miyako, Ishigaki, Kohama, Taketomi, Iriomote, Yonaguni). It showed that the Yonaguni population exhibits low genetic diversity, high inbreeding, and clear genetic differentiation from other populations. Gene flow between Ishigaki and Miyako through small stepstone islands might be preventing inbreeding of the Miyako population.We provide for the first time indirect proof of long-distance inter-island dispersal in the Ryukyu flying fox and revealed genetic diversity, gene flow and genetic differentiation among populations of the archipelago. These results will be useful for delineating conservation units and designing specific conservation policies for each island based on metapopulation genetic structure.
