Dipterocarpaceae is known as a very important tree family both biologically and economically.  Its distribution around the world covers the areas of Peninsular Malaysia, the Philippines, Sumatra, Kalimantan, Java, Sulawesi, Maluku to Papua.  Dipterocarpaceae family has a high economic value, such as producing wood, balsam, resin, charcoal, fat, fruit, bark, essential oil, and camphor. Its products have very important roles for domestic use and export needs. As  representatives of Dipterocarpaceae, the economic value of Shorea Roxb. ex Gaertner f, Dipterocarpus Gaertner f, and Dryobalanops Gaertner f will be discussed. Considering the very important role of Dipterocarpaceae, both biologically and economically, it is necessary to handle it sustainably, through the following actions such as conservation of genetic resources, seed physiology, seed handling, seedling ecology, root symbiosis and nutrition, pest and disease, management of natural forest, and plantation, and also non-timber forest product from Dipterocarpaceae. Dipterocarpaceae dikenal sebagai famili pohon yang sangat penting baik secara biologis maupun ekonomis. Penyebarannya di seluruh dunia meliputi wilayah Semenanjung Malaysia, Filipina, Sumatera, Kalimantan, Jawa, Sulawesi, Maluku hingga Papua. Famili Dipterocarpaceae memiliki nilai ekonomi yang tinggi, seperti menghasilkan kayu, balsam, damar, arang, lemak, buah, kulit kayu, minyak atsiri, dan kapur barus. Produk-produknya memiliki peran yang sangat penting untuk kebutuhan domestik dan ekspor. Sebagai perwakilan Dipterocarpace, nilai ekonomi Shorea Roxb. ex Gaertner f, Dipterocarpus Gaertner f, dan Dryobalanops Gaertner f akan dibahas. Mengingat peranan Dipterocarpaceae yang sangat penting, baik secara biologis maupun ekonomis, maka perlu dilakukan penanganan secara berkelanjutan, melalui tindakan-tindakan seperti konservasi sumber daya genetik, fisiologi benih, penanganan benih, ekologi semai, simbiosis dan nutrisi akar, hama dan penyakit, pengelolaan hutan alam, dan perkebunan, serta hasil hutan bukan kayu dari Dipterocarpaceae.

This paper will compare and contrast the reasons and statistics of development of negative health affects experienced by farmers and farm workers exposed to pesticides in both developed and developing countries. Several studies have suggested that a constant and close exposure of pesticides have negative affect on those who work closely with them. In developed countries farmers and farm workers have a lower risk of being affect by pesticides, whereas, in developing countries many workers face several disadvantages that affect the opportunities that they may be afforded. Countries in which one can clearly examine these specific global issues include developing countries such as: Ecuador, Fiji, Philippines and Costa Rica. These countries have the lack of knowledge surrounding pesticides, outdated technology, and the economic value of crops outweighing the value of human health. Whereas, within developed countries, such as the United States that are afforded more technology and that are scientifically aware and knowledgeable about pesticides, farmers and farm laborers experience improved circumstances and statistics that surround the use of pesticides amongst agricultural workers and farmers. Being that farmers and farm workers from both developed and developing countries are individuals who treat and nurture agricultural lands closely, including the application of pesticides; they inhale a high concentration of the chemicals. Another contributing factor to the inhaling of high concentration is the amount of time each worker spends concocting the mixture of insecticides, fungicides, herbicides, nematocides (used to kill nematodes, elongated cylindrical worms), and rodenticides and applying the mixture to the crops. Creation of the mixture, application of pesticides, and disposable of pesticide containers contribute in making the farmers and farm workers high at risk for developing pesticide related illnesses. By researching and further examining the various circumstances that surround the production and application of pesticides, what will be determined are what types of acute or chronic illnesses emerge and why are they more prevalent in developing countries rather than developed countries.

Abstract. Tolentino PJS, Navidad JRL, Angeles MD, Fernandez AP, Villanueva ELC, Obena RDR, Buot Jr IE. 2020. Review: Biodiversity of forests over limestone in Southeast Asia with emphasis on the Philippines. Biodiversitas 21: 1597-1613. 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 and Myanmar (1 sp.); and Limestone areas in Vietnam. Pteridophytes were recorded in Malaysia (32 spp.) while Bryophytes are recorded in Peninsular Malaysia (59 spp.). In the Philippines, there are plant records in: Masbate (61 spp.); Isabela (169 spp. Pteridophytes); Bohol (12 spp.), and Samar forests over limestone (29 spp. palms and 20 spp. orchids). A floral assessment in Samar Island Natural Park (SINP) includes species (212 spp.) that can possibly be found but are not limited to karsts. New Philippine endemic species are also recorded in Cebu, Palawan, and Panay Island. There are animal records in SEA including Vietnam (Bats-36, Bird-1, and Langurs-5 spp.); Malaysia (Sciuridae-1, Bats-28, Birds-129, Reptiles-17, and Invertebrates-74 spp.); Thailand (Murids-12, Reptiles-11, and Amphibian-1 sp.); and Myanmar (Reptiles-15 spp.). Records in the Philippines include: Mammals (Bicol-9, Mt. Irid-24, Mt. Aruyan-1, and Cebu-1 species), and; Birds (Cebu-1 sp.). A terrestrial faunal assessment in SINP includes species (182 spp.) that can possibly be found but are not limited to karsts. Forests over limestone are still largely understudied and the potential of discovering species is high. Further research is critical to establish science-based initiatives and policies that will protect and conserve limestone ecosystem biodiversity while allowing the utilization of its biological resources at a sustainable level.

Malaria cases caused by the zoonotic parasite Plasmodium knowlesi are being increasingly reported throughout Southeast Asia and in travelers returning from the region. To test for evidence of signatures of selection or unusual population structure in this parasite, we surveyed genome sequence diversity in 48 clinical isolates recently sampled from Malaysian Borneo and in five lines maintained in laboratory rhesus macaques after isolation in the 1960s from Peninsular Malaysia and the Philippines. Overall genomewide nucleotide diversity (π = 6.03 × 10−3) was much higher than has been seen in worldwide samples of either of the major endemic malaria parasite species Plasmodium falciparum and Plasmodium vivax. A remarkable substructure is revealed within P. knowlesi, consisting of two major sympatric clusters of the clinical isolates and a third cluster comprising the laboratory isolates. There was deep differentiation between the two clusters of clinical isolates [mean genomewide fixation index (FST) = 0.21, with 9,293 SNPs having fixed differences of FST = 1.0]. This differentiation showed marked heterogeneity across the genome, with mean FST values of different chromosomes ranging from 0.08 to 0.34 and with further significant variation across regions within several chromosomes. Analysis of the largest cluster (cluster 1, 38 isolates) indicated long-term population growth, with negatively skewed allele frequency distributions (genomewide average Tajima’s D = −1.35). Against this background there was evidence of balancing selection on particular genes, including the circumsporozoite protein (csp) gene, which had the top Tajima’s D value (1.57), and scans of haplotype homozygosity implicate several genomic regions as being under recent positive selection.

Eutropis rugifera has long been identified as a widespread species complex distributed in Nicobar, Peninsular Malaysia, Greater Sundaic Islands, Bali, Sulawesi and the Philippines. This skink was described by Stoliczka in 1870 from Nicobar Island based on a single specimen (holotype by monotypy). Later, Peters (1871), Bartlett (1895) and Werner (1896) described three more species which were morphologically similar to Euprepes percarinatus (from Java), Mabuia rubricollis (Borneo) and M. quinquecarinata (Sumatra) respectively, which are currently considered junior objective synonyms of Eutropis rugifera. We examined all the available synonym types and voucher specimens of Eutropis rugifera deposited at several museums. A morphological examination of the types of this species and mtDNA analysis (584 bp of 16S rRNA) of the samples from different biogeographic regions revealed that Eutropis rugifera from Nicobar Island, Bali Island, and Bawean Island are composed of a monophyletic species. However, the taxonomic status of the above population requires further clarification, and the population in Bawean Island may represent a cryptic species. Finally, we provide a complete redescription of E. rugifera based on its holotype.

KIEW, R. 2020. Towards a Flora of New Guinea: Oleaceae. Part 1. Jasminum, Ligustrum, Myxopyrum and Olea. Reinwardtia 19(1): 1‒25. ‒‒ Oleaceae in New Guinea is represented by five genera and about 32 species, namely Chionanthus (about 16 species), Jasminum (10 species), Ligustrum (3 species), Myxopyrum (2 species) and Olea (1 species). A key to genera as well as descriptions of and keys to species of Jasminum, Ligustrum, Myxopyrum and Olea are provided. Of the three Ligustrum species, L. glomeratum is widespread throughout Malesia, L. novoguineense is endemic and L. parvifolium Kiew is a new endemic species. Six species of Jasminum are endemic (J. domatiigerum, J. gilgianum, J. magnificum, J. papuasicum, J. pipolyi and J. rupestre). Jasminum turneri just reaches the northern tip of Australia; of the two species from the Pacific Islands J. simplicifolium subsp. australiense just reaches SE Papua New Guinea and J. didymum, a coastal species, reaches into Malesia as far north as E Java; J. elongatum is widespread from Asia to Australia. Neither Myxopyrum species is endemic: M. nervosum subsp. nervosum extends from Peninsular Malaysia to Indonesian New Guinea, and M. ovatum from the Philippines to the Admiralty Islands. The sole species of Olea, O. paniculata, stretches from Java to Australia and New Caledonia.

Forest products are materials gotten from forest, for the direct consumption or commercial use such as timber and non-timber forest products. The destruction of forest in Andoni due to the exploration and consumption of forest products are done without determining the values of these products that could have been lost. This study attempts to determine the value of identified forest products information gathered through the use of questionnaire focus group discussion, field survey and other related materials. The simple percentage analysis shows that forest products have a lot of value to the people; hence community dwellers involved in it. Conclusively, forest product were identified and categorized into wildlife species (wild animal) and plant species which usefulness were been influenced by socio-external factor, economical factor and livelihood security factor. The economic value of forest product in a study area is N532,351,300.00 while the expected value is N865,648,300.00. Therefore, the government at all levels should provide indiscriminate exploitation of premature forest product policy on forest management that are appropriate. These should be made to effectively reflect and enhance forest protection and improvement of livelihood of the people.

AbstractThe popularity of the Common Green Iguana (Iguana iguana) as a pet has contributed to its global occurrence as an invasive alien species. Early detection and control of invasive alien I. iguana populations is necessary to prevent the need for large and financially demanding eradication actions. Here, we collated information from digital footage and interviews regarding sightings of free roaming I. iguana specimens in Singapore and Thailand, and present evidence of early-stage invasions and establishment. Using species distribution modeling, we find that large parts of Thailand and neighboring countries have suitable habitat, which could facilitate the expansion of these alien populations if left uncontrolled. Additionally, we report singular I. iguana sightings in Hong Kong and Peninsular Malaysia. We call for awareness of alien I. iguana in the Philippines due to the high number of pet iguanas and reported CITES importations as well as the availability of suitable habitat throughout the archipelago. Further, we identify I. iguana presence to be facilitated by the release of pet-traded specimens and uncontrolled exhibition practices in recreational parks. We provide recommendations for implementing monitoring and eradication efforts and strategy recommendations to halt future spread and release.
