Frog species diversity of Mekongga Mountains, Southeast Sulawesi has never been published yet. Results of biodiversity exploration in 2010 and 2011 found 18 species of frog along the mountain at elevation 400 m to 2500 m asl. Of 18 frog species, seven are valid species, while 11 species are still in the process of description. Seventeen species endemic to Sulawesi and only one species is not endemic, it is Kaloula baleata; six species have wide distribution, they are Ingerophrynus celebensis, Oreophryne variabilis, Hylarana mocquardii, Occodozyga semipalmata, Polypedates iskandari and Rhacophorus edentulus; while most of the species that have been described were also found in central part of Sulawesi. Oreophryne sp. which found on elevation 2500 m ASL is the only one endemic species to Mekongga Mountains. Along elevation 400 m to 2500 m ASL, the elevation on 400 m asl and elevation 900-1000 m asl have the highest diversity of frog species, where reached 9 species. We report the characetristic of frog sound along the mountain tract. Moreover, the sounds characteristic of two endemic species, i.e. Oreophryne spp. and Ingerophrynus celebensis are the novelties of this study.
Karawang Regency was the largest producer of frog meat for Fejervarya cancrivora or Paddy Field Frog in West Java. To determine the population dynamics of Paddy Field Frog in the wild, two surveys were carried out in Karawang Timur. First survey was conducted on May 16-27th, 2016 and second survey on March 16-29th, 2018. Sampling was carried out using transect method with a total transect length was 3000 meters in similar sites. The first survey divided the paddy fields into dry and wet sites. However, during second survey, the paddy fields are mostly wet with average paddy crop height of 30 cm. The results of interviews with frog hunters were not much done in the March 2018 survey, because all the frog hunters interviewed in May 2016 were no longer hunting frogs. The impact of the reduction in hunting of the Paddy Field Frog in the Karawang area can be seen from the results of the population survey in March 2018; increasing on the density of adult individuals in the area of 5m2 in most transect areas when compared with the May 2016 survey.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
