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.

Subsequently, Canthium sensu stricto ( s.s. ) was re-delimited to species having paired supra-axillary spines, which led to the reinstatement of various genera in the Vanguerieae such as Keetia, Psydrax and Pyrostria . This raised questions on the generic affiliations of Philippine Canthium species as most of its members lacked spines. In an effort to revise the Philippine Canthium , the endemic spineless Canthium subsessilifolium was collected to ascertain its generic affiliation within the tribe using plastid ( trnL-F region) and nuclear (ITS region) markers. The majority-rule consensus tree of combined data sets showed a wellsupported clade of the whole Vanguerieae (PP=1.00). Interestingly, C. subsessilifolium was nested within the robustly supported Pyrostria clade (PP=1.00). Morphological similarities of C. subsessilifolium with Pyrostria further supported our molecular results. Therefore, a new combination is here provided: Pyrostria subsessilifolia (Merr.) Arriola & Alejandro. This study establishes for the first time the existence of Pyrostria in the Philippines.

Some basic leaf architectural characters can also be used in describing certain clades within the family.

Due to its unique morphology, the position of the small genus in the tribe Marsdenieae of Asclepiadoideae was previously in question. In this first molecular study of Clemensiella , the internal transcribed spacer (ITS, nrDNA) region of three isolates were newly generated and analyzed together with previous published sequences. The present aims to assess the phylogenetic positon, monophyly and closely-related genera of Clememsiella . The three Clemensiella isolates yielded a total of 630 to 642 base pairs (bp) and the average GC content ranged from 63.21% to 63.86%. Based on the strict consensus tree, the monophyly of Clemensiella is highly supported with BS = 100% and nested within the tribe Marsdenieae with BS = 61%. This study confirms the phylogenetic position of Clemensiella in Marsdenieae and its close relation to Dischidia and Hoya . Although the three Marsdenieae are distinct in their seed structures, they share common features in habit, inflorescence and corolla aestivation.

Their potential industrial application merits a thorough study of these microorganisms. Thus, our research study aimed to isolate and characterize marine yeasts from several substrata collected from Calatagan, Batangas. Marine yeasts were isolated using enrichment culture of seawater, marine sediments, and living and decaying seagrasses and seaweeds on Glucose-Yeast Extract-Peptone broth (GYPS) supplemented with 33 g/L marine salts. Following incubation at room temperature, a total of 13 yeast strains were isolated. Most of the marine yeasts were obtained from either living or decaying seagrasses. Growth on GYP Broth with and without salt showed that six out of the 13 isolates were able to grow in the presence or absence of marine salts. Characterization of the isolated marine yeasts was done using the conventional morphological and biochemical methods and modern molecular techniques. All marine yeasts have cream-colored, circular and convex colonies with entire margin. The cells were spherical with a size range of 2.5 – 12.5 μm. They utilized galactose, maltose, sucrose, trehalose, xylose, sorbitol, N-acetyl-glucosamine and 2-keto-gluconate. Only one isolate (PCL08-LG04) utilized glycerol, arabinose, cellobiose, and raffinose. Comparison of the API 20C Aux profiles with the API database indicated that the isolated marine yeasts have affinity to the genus Candida. Gene sequence analysis of their ITS 1 and 2 regions of nuclear rDNA identified the isolates as Candida tropicalis and Pichia carribica.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70067822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
