Generally, the leaves may be categorized into two groups based on lobation. The results of the cluster analyis support the transfer of R. korthalsii to the genus Epipremnum. Further, the leaf morphology was able to define the interspecific relationship within Rhaphidophora. However, in establishing the intergeneric relationship between Epipremnum and Rhaphidophora, the leaf morphology does not offer conclusive evidence.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70067133","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}

They are involved in many biological interactions as some strains can enhance plant growth (Ivanova et al., 2001; Koenig et al., 2001; Lidstrom and Chistoserdova, 2002) and protect some plants against fungal pathogens (Madhaiyan et al., 2004). Green (2001) observed that PPFM bacteria can be isolated from vehicular exhaust and soot, as these bacteria are able to degrade aliphatic and aromatic hydrocarbons. Furthermore, Popp et al. (2006) revealed that PPFM bacteria may be part of the consortia of microorganisms involved in the degradation of mineral oil in soil. These characteristic features give PPFM bacteria as possible pollution indicators. Considering the potential of this group of microorganisms to be utilized in bioremediation and biotechnology, study on this group is needed (Lee, 2007). Hence, this study was conducted to answer the dearth of information regarding local PPFM bacteria. The objective of this study was to isolate and characterize PPFM bacterial isolates from soil samples exposed to vehicular soot. Specifically, it was aimed at describing PPFM bacteria from soil collected along the island pavement of Taft Avenue fronting DLSU-Manila campus.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2009-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70067928","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}

In this study, a monitoring of the abundance and distribution of B. braunii in Paoay Lake was done in 2006. Samples were taken from the surface and deep portions in the lake from 4 sampling sites. The density of B. braunii was found to increase with time from an average of 9,670 colonies/L in May to 24,656 colonies/L in June. The highest recorded density was 44,732 colonies/L near the area surrounding the town of Nagbacalan in July. It was also found that the abundance of some zooplankton species was lowered when the abundance of B. braunii was elevated in the lake. This study showed that the B. braunii bloom has likewise caused a decrease in dissolved oxygen and might have attributed to the toxic effects exerted by this green alga on the other organisms found in the lake. This is the first reported occurrence of a B. braunii bloom in Paoay Lake.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2009-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70067874","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}

The new species is related to Eutropis rugifera, which is a secretive, forest-adapted skink that ranges widely outside the Philippines from the western extent of its distribution on Nicobar Island (the type locality) through southern Peninsular Malaysia, Sumatra, and the Mentawai islands, Borneo, Java, and as far east as Bali Island. The discovery of a new, morphologically distinct, and genetically highly divergent Sun Skink lineage in the low elevation forests of the Zamboanga Peninsula creates a puzzling disjunct geographic distribution (E. rugifera has not been reported from the Sulu Archipelago). The new species is estimated to have diverged ~10–16 mya from E. rugifera, from which it appears to have an extralimital and isolated distribution. Considering the dynamic geological history and ancient continental origin of the Zamboanga Peninsula, colonization by the new species may have been facilitated by pre-Pleistocene overseas long-distance dispersal, saltatory range expansion, and subsequent contraction/extinction in the Sulu Archipelago, and/or possibly paleotransport on the ancient crustal fragment of Zamboanga. The new species is known only from Zamboanga City’s primary surface water supply catchment at the lowest elevations inside the boundaries of Pasonanca Natural Park, despite the fact that there have been historical surveys of herpetological diversity at multiple sites to the northeast (Zamboanga, western Mindanao) and to the southwest (Sulu Archipelago). The new species, thus, may be limited to just the tip of the Zamboanga Peninsula, possibly rendering\u0000\u0000KEYWORDS: IUCN Red List, Palawan microcontinent block, Pasonanca Natural Park, Sulu Archipelago, Surface catchment watershed biodiversity","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69122336","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}
