摘要

通过对西卡图纳拉贾保护区草地、农区和次生林生境蚯蚓的种类组成、多样性和丰富度进行调查。鉴定出6个土生蚯蚓形态种，推定为新种。其中包括一种羊绒属、三种多花属和两种多花属。此外，草地和农区蚯蚓数量最多，次生林中蚯蚓数量最少，属入侵种蓬索(pontocolex corethrurus)。物种丰富度较低的次生林多样性指数较高。农业和草原地区多样性水平较低。土地利用和非生物因子可能与不同生境下蚯蚓群落的组成有关。必须进行进一步的研究，以保护和可持续地管理其生物多样性和生境。

Earthworm diversity and populations in different habitats of Rajah Sikatuna Protected Landscape, Bohol, Philippines

An earthworm survey was conducted to determine the species composition, diversity, and species richness in the grassland, agricultural areas, and secondary forest habitats of Rajah Sikatuna Protected Landscape (RSPL). Six indigenous morphospecies of earthworms were identified, which are putatively new species. These include one Amynthas species, three Polypheretima species, and two Pheretima species. Also, Pontoscolex corethrurus, an invasive species was found to be the most abundant species of earthworm in grassland and agricultural areas but not in the secondary forest. The diversity index showed a high level in the secondary forest with low species richness. Agricultural and grassland areas showed a low level of diversity. Land use and abiotic factors can be related to the composition of earthworm communities in different habitats. Further studies must be conducted for the conservation and sustainable management of its biodiversity and habitat.

期刊介绍： The Philippine Journal of Systematic Biology (Print ISSN: 1908-6865; Online ISSN: 2508-0342) is an annual, peer-reviewed journal in English that publishes high quality reports of original research and reviews in the field of Taxonomy & Systematics, Ecology and Conservation Biology. The PJSB is a CHED recognized journal under CHED CMO 50 series of 2017. It is also included in the Clavariate Analysis (formerly a subsidiary of Thomson Reuters) Master Journal List under Zoological Record, BIOSIS Previews and Biological Abstracts.The PJSB is the official publication of the Association of Systematic Biologists of the Philippines (SEC Registration: Association of Philippine Taxonomists, Inc.). The organization financially supports the journal and all its endeavors. The journal aims to build up quality information on animal, plant and microbial diversity in the Philippines. Articles dealing with original research or reviews in Zoological, Botanical or Microbial Systematics, Ecology and Conservation Biology are welcome. Authors are advised to consult a recent issue of PJSB for the current format and style. All manuscripts are reviewed by at least two qualified referees.
