Baseline coral assessments were conducted in selected sites in the four provinces of the VIP (Batangas, Marinduque, Occidental Mindoro, and Oriental Mindoro) to compare coral abundance and biodiversity in Marine Protected Area (MPA) and non-MPA sites that were subjected to anthropogenic stressors. A total of eight sites were surveyed to measure average hard coral cover (HCC) relative to other benthic components. Generic richness and the dominant coral genera were also obtained for the eight sites. The average HCC and generic richness of Batangas MPA and Batangas non-MPA were (39.82 ± 7.59%, 22 coral TAUs) and (38.80 ± 5.56%, 27 coral TAUs), respectively. The average HCC and generic richness of Marinduque MPA and Marinduque non-MPA were (25.58 ± 2.37%, 13 coral TAUs) and (35.73 ± 4.05%, 17 coral TAUs), respectively. The average HCC and generic richness of Occidental Mindoro MPA and Occidental Mindoro non-MPA were (49.49 ± 4.50%, 26 coral TAUs) and (32.32 ± 5.60%, 19 coral TAUs), respectively. The average HCC and generic richness of Oriental Mindoro MPA and Oriental Mindoro non-MPA were (25.02 ± 4.72%, 24 coral TAUs) and (5.93 ± 2.10%, 10 coral TAUs), respectively. Batangas non-MPA and Marinduque non-MPA showed potential to become MPAs due to their higher HCC and generic richness which were attributed to natural disturbances and duration of local reef management in their MPA counterparts. Continued monitoring and assessment should be done to build on the growing database of biodiversity data that is being compiled for the VIP.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139359477","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 taxonomy and distribution of these endemic cuckoos are poorly known. Recent distribution data of these cuckoos showed broader distribution patterns in the islands of Luzon, Catanduanes, and Marinduque; however, morphometric variations among these island populations are still unknown. While both species are sexually monomorphic, the differences between sexes were mainly based on plumage coloration. Dasylophus superciliosus is composed of two subspecies: ssp. superciliosus (Southern Luzon) and ssp. cagayanensis (Northern Luzon). The separation of the two subspecies of D. superciliosus was determined by the differences in superciliary feather, the coloration of breast plumage, and the tail band. In this study, we investigated the morphometric variations (1) between subspecies of D. superciliosus, (2) among island populations, and (3) between sexes (sexual dimorphism) of the two malkoha species. Four linear measurements (bill length, wing length, tarsus length, and tail length) were measured from 184 museum specimens. Results showed that the Catanduanes group (n=10) of L. cumingi exhibited a smaller body size than the Marinduque group (n=9). Red-crested Malkoha D. superciliosus showed significant differences between its two subspecies where the ssp. cagayanensis (n=28) exhibited smaller body size (bill length, wing length, and tail length) compared to ssp. superciliosus (n=81). Lastly, this study confirms that the two malkoha species are sexually monomorphic based on the analyzed morphometric data.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135091028","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}

Trees are an important part of the vegetation that play a fundamental role in stability and provide services in the forest ecosystem and resources for human consumption. Tree species diversity in Mt. Agad-Agad, Iligan City has not been studied, hence an inventory of trees was conducted to assess their conservation and ecological status including their economic uses. A series of transect walks along the trails were employed. Voucher specimens were collected, processed, and identified. Results revealed a total of 127 species of trees distributed into 40 families and 97 genera. The most represented families were Moraceae with 15 species, Arecaceae and Fabaceae with 9 species each, Euphorbiaceae with 8 species, Burseraceae with 7 species, Rubiaceae and Rutaceae with 6 species each and Anacardiaceae, Meliaceae and Myrtaceae with 5 species each. Of these tree species, 18 are Philippine endemics, 2 Mindanao endemics, 4 (IUCN, 2021-3) and 2 (DENR, 2017-11) endangered, 2 (IUCN, 2021-3) and 5 (DENR, 2017-11) vulnerable, 79 (IUCN, 2021-3) and 6 (DENR, 2017-11) least concern, 5 (DENR, 2017-11) other threatened species, and 5 (IUCN, 2021-3) and 1 (DENR, 2017-11) near threatened. Most of the trees were economically important as food, medicine, timber, handicrafts, building materials and ornamentals. Numerous anthropogenic threats included introduction of non-native tree species for forest rehabilitation, conversion of forest to agricultural land and improper garbage disposal.

A 7-year observation was conducted to determine the species composition of butterflies and food plants in an urban residential garden in Bago City, Negros Island. Using visual encounters and photo-documentation, the butterfly inventory was done from October 2013 to December 2020 while the food plant inventory covered only two years (2018–2020). The results revealed a total of 88 butterfly species belonging to five families and 60 genera, of which 20 species were classified as residents, 26 seasonal, and 42 vagrants. Despite the very low endemism (8%), it is noteworthy that four species are new island records: Parnara bada, Potanthus pava, Suastus gremius, and Tagiades trebellius martinus. For the food plants, 80 species from 33 families and 73 genera were identified, of which 37 species are recognized as larval host plants, 49 as nectar plants, and six as both larval host and nectar plant sources. Interestingly, a residential garden with such a small size could harbor 27% of Negros island’s and almost 10% of the country’s butterfly species. Species richness for both butterflies and food plants are high, which supports the idea that gardens could be an alternative habitat for wildlife in highly urbanized areas. Future studies should consider measuring the diversity for both taxa as well as environmental factors affecting butterfly and plant communities in a residential garden.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44840810","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}
