Summary - The nematode diversity in soil and litter was investigated on Mount Hamiguitan, the Philippines, along four eco-habitats from elevations of 75-1600 m a.s.l. A total of 155 and 467 nematodes were identified to 39 and 62 genera from litter and soil, respectively. The nematode assemblages and diversity did not show any relation to eco-habitat or elevation. Bacterivorous nematodes were the most common group (37.5%). Acrobeloides was most abundant from the soil and Aphelenchoides from the litter. Bicirronema hamiguitanense n. sp. is herein described based on morphology, morphometrics and molecular data. The new species has the following diagnostic features: a wide lateral field one-fifth of its body diam. with four incisures forming two ornamented ridges; gubernaculum with proximal thickening; spicules (35-38 μm) and gubernaculum (18-20 μm) longer than B. caledoniense; and with 37 molecular autapomorphies supporting its new species status. The phylogenetic position of the new species within Cephalobomorpha is discussed. © Koninklijke Brill NV, Leiden, 2015.

Birds are crucial to maintaining the balance of many ecosystems by providing various ecological services. The diversity of birds and their feeding guilds in different land-use types were investigated in south-central Mindanao to elucidate the effect of disturbance and habitat modification on bird communities. Point count method was employed to identify birds in three habitat types: i) agroforests; ii) ricefields; iii) roads and heavily disturbed areas. A total of 1114 bird sightings were recorded that included 33 species of 24 families; of these, 3 were Philippine endemics, and 5 were migrant species. Among all of the habitat types, the highest species diversity was found in agroforests (1/D = 16.148), and the lowest was recorded from roads and heavily disturbed habitats. The species composition of agroforests was more similar to ricefields than to areas with high levels of disturbance, such as roads. The characteristic of the vegetation and the availability of food resources may be vital to the diversity of birds in every habitat as evidenced by the high species richness of frugivores and insectivores in agroforests and ricefields, respectively, where food source is largely available. The observation of Streptopelia tranquebarica was a new record for Mindanao, and it was particularly sighted in ricefields. Therefore, this study indicates that land-use change and modification may alter bird diversity structure, and the maintenance of the vegetation in land-use types as food and resource, and as habitat is essential to the conservation of the native and ecologically-important bird species in south-central Mindanao.

Indigenous people play a major role in the conservation of wildlife species in protected areas. This paper provides an insight on the involvement of indigenous people in protecting and hunting of wildlife species in Mt. Apo National Park, Mindanao Island, Philippines. Here, I assessed indigenous knowledge and practices towards wildlife hunting from three villages from Mt. Apo through immersions, interviews, and focus group discussion between May 2014 and January 2015. The majority of wildlife hunters I encountered were male and married between the ages of 35-60 years old. Commonly hunted wildlife species from the national park included large wildlife species such as the endemic and threatened Philippine Warty Pig Sus philippensis, Philippine Brown Deer Rusa marianna, Common Palm Civet Paradoxurus hermaphrcditus, Reticulated Python Malayopython reticulatus, Common Monitor Lizard Varanus satvator and other large birds such as Rufous Hornbills Buceros hydrocorax, large dove species (i.e., Dacula spp.). In the past, wildlife hunting was most commonly done for sustenance and culture. But, poverty and the lack of alternative livelihoods have become a recent motivation to hunt wildlife. This current findings in this study suggest that wildlife are essential for indigenous people in protected areas, however, hunting practices should be monitored and provide alternative livelihood options to reduce threats. This study introduced the vital links between local communities and wildlife in protected areas. Thus, engaging and empowering indigenous people and local communities in wildlife protection combined with appropriate conservation planning are the first steps forward in attaining sustainable and effective local conservation in protected areas. © Tanalgo 2017.

Bat association to microorganisms such as fungi has become a concern to many wildlife ecologists. This study aimed to identify fungal species present from common frugivorous bats in southcentral Mindanao, Philippines. Agro-economically important fungal species were sampled from different body parts of common fruitbats. The fungal samples were grown and purified on Sabouroud Dextrose Agar medium. A total of 58 fungal isolates under three fungal genera (Aspergillus, Penicillium, and Fusarium) were morphologically identified. Among fruitbats, Cynopterus brachyotis has the highest number of isolates. While Aspergillus was the most common fungal group recorded among fruitbats. Consequently, the result of this study will open the investigation on the roles of agroeconomic fungal groups in the ecology and conservation of frugivorous bats. © Beijing Academy of Agriculture and Forestry Sciences.

The root-knot nematode, Meloidogyne graminicola, can cause substantial rice yield losses. Understanding the mechanisms of resistance to this nematode species in known resistant rice genotypes may help to improve rice genotypes, aiming at developing and implementing environment-friendly and cost-effective nematode management strategies. Using susceptible and resistant rice genotypes, a comparative analysis of histological response mechanisms was made during two phases of the nematode colonisation: i) root penetration; and ii) subsequent establishment and development by M. graminicola second-stage juveniles (J2). Two types of defence response mechanisms could be distinguished in the resistant rice genotypes. The early defence response consisted of a hypersensitive response (HR)-like reaction in the early stage of infection characterised by necrosis of cells directly affected by nematode feeding. This HR-like reaction was observed only in the M. graminicola-resistant Oryza glaberrima genotypes and not in the M. graminicolasusceptible O. sativa genotypes. The late defence response took place after the induction of giant cells by the J2. Giant cells usually collapsed and degenerated before J2 developed into adults. Structural features of the roots of the susceptible O. sativa showed greater root and stele diam. and cortex thickness than the resistant O. glaberrima genotypes. Desired features of plants with resistance to M. graminicola elucidated in this study can be used for selection of plants for breeding programmes. © Koninklijke Brill NV, Leiden, 2014.

Migration, penetration, development and reproduction of the rice root-knot nematode, Meloidogyne graminicola, in the resistant African rice genotypes TOG5674, TOG5675, CG14 and RAM131, and in the susceptible Asian rice genotypes IR64 and UPLRi-5 were studied and compared. The number of second-stage juveniles (J2) that had migrated horizontally and vertically towards the rhizosphere at 48 h after inoculation was comparable in both resistant and susceptible rice genotypes. Penetration of J2 was significantly lower in the resistant rice genotypes compared with the susceptible rice genotypes at 3 and 7 days after inoculation (DAI). Nematode development in the resistant rice genotypes was slower than in the susceptible rice genotypes. Nematode reproduction was significantly lower in the resistant rice genotypes, which supported fewer eggs per g of roots and eggs per female. A significantly higher percentage of egg-laying females was found in the susceptible rice genotypes. Mature females that had developed in the resistant rice genotypes were significantly smaller than the ones in the susceptible rice genotypes. The resistant rice genotypes had significantly fewer galls than the susceptible rice genotypes. © 2012 Koninklijke Brill NV, Leiden.

Vibrio owensii is one of the most virulent vibrios known being able to kill crustacean larvae at 102 CFU ml-1. This study describes virulence changes to naïve strains of Vibrio harveyi and Vibrio campbellii when infected with the bacteriophage VOB from a closely related species V. owensii 47666-1. The bacteriophage from V. owensii was induced into lytic phase by using mitomycin C at 100 ng ml-1. One strain of V. harveyi and two strains of V. campbellii from 29 tested containing no prophage were susceptible to lysogenic conversion with VOB. Virulence changes induced in Harveyi clade bacteria included the up-regulation of protein secretion, statistically significant increased haemolysin and chitinase production and increased mortality to nauplii of Penaeus monodon. No change in siderophore production was observed. Bacteriophage VOB is likely to be responsible for some of the virulence factors expressed by V. owensii. As this bacteriophage is able to infect strains of V. harveyi and V. campbellii this phage may contribute to increased virulence of other vibrios in aquaculture and in the natural environment. © 2013 Indian Virological Society.

The biochemical changes in two Selaginella species namely, S. tamariscina (Beauv.) Spring and S. plana (Desv. ex Poir.) Heiron., as induced by desiccation and subsequent rehydration were explored. Plants were allowed to dehydrate naturally by withholding irrigation until shoot’s relative water content (RWC) reached <10%. After which, dehydrated plants were watered until fully rehydrated states were obtained which was about 90% RWC or more. Desiccation-tolerance characteristics were observed in S. tamariscina while desiccation-sensitivity features were seen in S. plana. Membrane integrity was maintained in S. tamariscina but not in S. plana as evidenced in the relative electrolyte leakage measurements during desiccation phase and the subsequent rehydration stage. Pigment analyses revealed conservation of some chlorophylls and carotenoids during desiccation and reaching control levels following rehydration in S. tamariscina. Very low pigment contents were found in S. plana during desiccation phase and the pigments were not recovered during rehydration attempt. Meanwhile, compatible solute determination showed rise in total sugar and proline contents of desiccated S. tamariscina only, indicating presence of biochemical protection machineries in this species and absence of such in S. plana during dehydrating conditions. These data indicate that one key element for desiccation-tolerance in lower vascular plants is the ability to protect tissues from severe damages caused by intense desiccation. © Penerbit Universiti Sains Malaysia, 2016.

Purpose - This paper aims to assess the vulnerability of the farmer-respondents in Southern Philippines, specifically Region XI and XII, to climate change. Design/methodology/approach - This study conducted an empirical analysis of the impact of climate change on maize (Zea mays), banana (Musa sapientum) and durian (Durio zibethinus) production. Furthermore, it estimated the determinants of adaptation to climate change and its corresponding effect on farm productivity. The analysis used primary data from 541 farmer-respondents producing maize, banana and durian in the 6 provinces and 18 municipalities of the sample areas. Findings - Based on the probit estimate results, farmers adaptation decisions were influenced by information about future climate change conditions, social capital, access to formal extension and farmer-to-farmer extension. The author found from the stochastic frontier estimation in the production function that climate change adaptations exerted a significant impact on farm productivity. It helped in coping with the adverse effects and risk of climate change while increasing agricultural productivities of the farmer-respondents. Originality/value - This research paper will be an addition to the body of knowledge on the socioeconomic aspects on the climate change and adaptation on the production of maize, banana and durian in the case of a developing country like Southern Philippines. This will bring more insights into the adaptation strategies that are crucial to cope with climatic variability and change. © EmeraldGroupPublishingLimited.
