MAJALAH LIMNOTEK Perairan Darat Tropis di Indonesia merupakan penerbitan berkala ilmiah di bidang limnologi dan kajian sumber daya perairan darat lainnya, yang terakreditasi sesuai dengan SK Kepala LIPI No. 659/AU3/P2MI-LIPI/07/2015, tentang Akreditasi Majalah Ilmiah LIMNOTEK, Perairan Darat Tropis di Indonesia. Diterbitkan dua kali setahun oleh Pusat Penelitian Limnologi, Lembaga Ilmu Pengetahuan Indonesia. Majalah ini diharapkan dapat berfungsi sebagai wahana diseminasi dan komunikasi hasilhasil penelitian dan pengembangan sumber daya perairan darat, khususnya di Indonesia.

Mahalona Lake is located in Towuti District, East Luwu Regency, South Sulawesi Province. Geographically, this lake is centered at 121°29’S – 2°36’E and administratively, is a conservation area for the Nature Tourism Park (TWA) of Mahalona Lake.

Lake Mahalona and its catchment area are important for global biodiversity, having qualified as a Key Biodiversity Area (KBA) which is defined as: “a site that contributes significantly to the sustainability of global biodiversity”, in terrestrial, freshwater and marine ecosystems. Furthermore, Lake Mahalona and
its catchment area are identified as an Alliance for Zero Extinction Site (AZE) which is defined as “a site that contributes effectively to the entire global population area of Critically Endangered or Endangered species (IUCN, 2016). The species in Lake Mahalona meeting the criterion A1e are the ones that make the site an AZE site presented in the table below.

Danau Matano adalah satu dari lima danau di wilayah Propinsi Sulawesi Selatan yang dikenal dengan nama Malili Kompleks. Keempat danau lainnya adalah Mahalona, Towuti, Wawontoa dan Masapi. Diantara kelima danau tersebut, Matano merupakan danau yang terletak di daerah yang tertinggi yaitu 382 m dari permukaan laut, sedangkan bagian terdalamnya mencapai 590 m. Satu tim peneliti yang berasal dari Pus’lit Biologi-LIPI, IPB dan Kehutanan mendapat dana dari Asean Regional Center for Biodiversity Conservation (ARCBC, yang merupakan badan ke{asama antara Asean dan Uni Eropa) untuk melakukan penelitian di kelima danau tersebut, ketiga danau tersebut di atas yaitu Danau Matano, Mahalona dan Towuti. Makalah ini merupakan hasil dari empat kali kerja lapang di Danau Matano, sedangkan keseluruhan rencana ke{a lapang adalah 7 kali, sehingga hasil ini merupakan studi pendahuluan.

Indonesia is the biggest archipelagic nation
with a length of coastline at 95.181 km [1] and angrove areas estimated at 3.244.018 ha, which is mainly distributed in Sumatera, Jawa, Kalimantan, Sulawesi, and Papua [2]. These mangrove areas are home to 35 % of fish in the world [2]. The Bone Gulf is one of the Indonesian waters located between South Sulawesi and Southeast Sulawesi, with a length of coastline at 1.128 km [3]. It bears mangrove areas, sandy beaches, and a coast planted with palm oil.

Lake Matano is located in the Sorowako area (South Sulawesi) and is one of the ancient lakes that make up the Malili Lake complex (Matano, Mahalona and Towuti). It is estimated that the lake was formed around 2-4 million years ago. Lake Matano is the oldest lake, around 2-4 million years old…

The Wallacea region has a high level of biodiversity and high endemic properties. Endemic flora and fauna in the Wallacea region are different from other species in another place, caused by the formation process and geological history that are not the same as other regions in the world. The presence of these endemic species is a feature of the transition region or meeting between the types of flora and fauna from the continents of Asia and Australia, causing this region have a special attraction for the world of conservation of flora and fauna.
