A new tarantula species of the genus Phlogiellus Pocock, 1897,
P. kwebaburdeos n. sp. is described and illustrated based on a series of specimens collected inside the Puting Bato Cave 3-4 in Burdeos, Polilio Island, Quezon Province, Philippines. P. kwebaburdeos Barrion-Dupo, Barrion and Rasalan n. sp., a cave-dwelling mygalomorph spider represents the fifth and sixteenth species of Phlogiellus reported in the Philippines and in Southand Southeast Asia, respectively.

A rapid assessment of spider diversity in Kabigan Falls, Pagudpud, Ilocos Norte, Philippines
Research Paper, pages 16-26

A rapid assessment of spider diversity in Kabigan Falls, Pagudpud, Ilocos Norte. Spiders are the most permeating predators in both agricultural and natural ecosystems. In ecological studies, they serve as indicators of environmental quality and as biological control agents in agricultural ecosystems. A total of 38 individuals collected from Kabigan Falls were comprised of 13 species. These species are from the family Araneidae, Sparassidae, Pholcidae, Salticidae, and Tetragnathidae. Most of the specimens collected from the site were under families Tetragnathidae and Araneidae. The most species-rich family is Araneidae (5). These include the following: Araneus inustus, Cyclosa insulana, Cyclosa mulmeinensis, Cyclosa spirifera and Larinia sp. Newly-recorded spiders include are Tetragnatha plena Chamberlin, 1924, a new Philippine record; and new locality distributed spiders are Chalcotropis luceroi Barrion & Litsinger, 1995 and Pholcus arayat Huber, 2011.

Gordonia terrae USTCMS 1066: its taxonomy, antimicrobials and imidazolium susceptibility and evaluation as an initial screening agent for anti-TB compounds and natural products

culture of the marine luminous bacterium: Vibrio fischeri USTCMS 1026. Subsequent investigation identified the actinomycete contaminant as MP 1066 for Mycobacterium phlei USTCMS 1066 but was later found to have morphological, physiological, biochemical and genotypic characteristics compatible with member species of the genus Gordonia. BLAST comparison
of MP 1066 yielded 100% 16S rDNA sequence alignment with Gordonia terrae so the strain was renamed as Gordonia terrae USTCMS 1066. Its antimicrobial susceptibility profile is similar to that of the pathogenic mycobacteria yielding small MICs and large inhibition zones against the antibiotics: ampicillin (AMP), azithromycin (AZT), amoxicillin-clavulanic acid (AUC), ciprofloxacin (CIP), ethambutol (ETHAM), isoniazid (INH), rifampicin (RIF), tetracycline (TET), sulfamethoxazole – trimethoprim (SXT), and streptomycin (STREP). In addition, the crude ethanolic extracts of Acanthella carteri, Alstonia scholaris Lunasia amara Blanco, Momordica charantia, Wrightia antidysenterica, Zingiber officinale and the pure synthetic imidazole: 1,3-bis(4-methylphenyl) imidazolium chloride likewise inhibited strongly the growth of Gordonia terrae USTCMS 1066. Substances that
strongly inhibited Gordonia terrae USTCMS 1066 were also observed to be strongly inhibitory to Mycobacterium tuberculosis indicative of its suitability as an initial assay organism for the screening of anti-TB natural products and synthetic compounds most specially for laboratories that are not equipped with Biosafety Level III facilities.
Abundance, size and symbionts of Catostylus sp. Medusae (Scyphozoa, Rhizostomeae) in Panguil Bay, Northern Mindanao, Philippines
Research Paper, pages 46-62

a showed a significant positive correlation with abundance suggesting an influence of planktonic food source. A total of 60 individuals of animal symbionts were observed including the crab Charybdis feriata, the carangid fish Alepes djedaba and the poicilostomatoid copepod Paramacrochiron sp. This study reported the first record of Catostylus sp. medusae in Panguil Bay.
