Palay-Palay Mataas-naGulod Protected Landscape (MPPMNGPL) and its immediate vicinities based on field surveys conducted on accessible localities in 1998, 2006, and 2009. A total of 14 species representing four anuran families in 10 genera were recorded from the area. Baseline data on species richness, habitat and altitudinal distribution, and natural history of anurans are presented. The anuran assemblage exhibited high levels of endemicity (57%). Anurans were recorded in elevations from as low as 40 masl to more than 600 masl with the non-endemic species generally distributed in the lowlands while most of the endemics were restricted to higher elevations. Majority of the non-endemic species were usually associated with human-modified habitats while most of the endemic species were restricted to forest habitats. Eight microhabitat types were identified and a large proportion of anurans occurred in bodies of water and forest floor litter.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70067683","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}

Our research study, then, aimed to isolate and characterize PNSB and determine their population count. Rice paddy soil samples were collected from San Jose del Monte, Bulacan, and were inoculated into completely filled culture vials pre-filled with different enrichment media, e.g. Larsen’s medium, Van Niel’s medium, and Acetate Yeast Extract (AYE) medium. Following incubation for 4 weeks under an incandescent bulb, only the AYE medium resulted to bright “red bloom” indicating growth of PNSB. Morphological and cultural characterization of the isolated PNSB showed pinpoint, red colonies and Gram negative, non-spore forming, thin, elongated (0.5 x 2.0 μm) rods. In vivo absorption spectrum using spectrophotometer showed the presence of bacteriochlorophyll a and carotenoids. The isolated PNSB utilized pyruvate, malate, glucose, lactate, citrate and soluble starch as its carbon sources, and ammonium sulfate, peptone and yeast extract as nitrogen sources. Preliminary identification identified the PNSB isolates as Rhodopseudomonas sp. MPN estimated low number of PNSB (2 cells per ml) in the collected rice paddy soil.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70067701","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}
