Abstract

Maros-Pangkep karst formation in South Sulawesi is one of the largest karst environments in the world. One cave located in the area is Leang Londrong and is a part of the management of Bantimurung-Bulusaraung National Park. The Leang Londrong area is known as tourism spot with water-based tourism as the main attraction and it is also known as the main ecosystem service provider in particular as water sources for many areas. This cave is inhabited by some species of bats. Even now the area is designated for water-based tourism, other potential tourism object such bats roosting inside the cave for tourism development has not been explored. Therefore, this study attempts to examine the perception of local community and tourists visiting the area towards nature, cave, bats and its conservation, as well as cave-bats tourism development. The study was conducted between January-April 2022 by distributing questionnaires to 86 respondents consisted of local community, tourists, and government’s representatives. The results indicated that in general the respondents had limited knowledge on nature, cave, bats and its conservation. In particular with bats, the majority of the respondents have not yet been familiar with bats, understood the roles of bats for the environment, and tended to ignore the existence of bats. However, in relation with nature and conservation, bat conservation, and the development of cave and bat tourism in Leang Londrong, all respondents from the tourist’s side agreed to support (>85%) and for the locals, the number was even higher (>90%). Therefore, from the perspectives of local community and tourists, the chance in developing cave and bat tourism in Leang Londrong can be considered possible.

Abstract

This study investigated the diversity and density of rhizosphere fungi in the post-nickel mining land of PT. Vale Indonesia Tbk., to assess its potential in supporting revegetation and ecological recovery. By analyzing fungal populations at various dilution levels in PDA media, this study revealed the relationship between post-reclamation duration and increased soil microbiological activity. The results showed that longer reclaimed land had denser fungal populations, especially at lower dilutions, indicating the importance of rhizosphere fungi in soil health recovery. This study confirmed that the presence of plants significantly affected the abundance and diversity of rhizosphere fungi. These findings provide insight into the importance of selecting specific fungal species for post-mining land revegetation strategies, which support plant growth and accelerate ecological recovery. It can contribute to developing best practices in ecological engineering and environmental management in post-mining areas.

Abstract

The sailfin lizard (Hydrosaurus celebensis) is a unique reptile species whose population may be threatened by habitat destruction as well as local and global trade. As an anticipation of extinction, sufficient ecological information is required to support its conservation efforts. On the other hand, information on its ecology is still limited. The aim of this study was to collect information on its feeding ecology. This study was conducted for 78 days from June to August 2022. Direct observations were made on sailfin lizards to determine when they started feeding and the species of plants and animals consumed. To determine the availability of forage plants, we set up 22 10 x10 m plots with 5 x 5 m subplots. The results showed that the sailfin lizard started to forage at noon. They ate more plants than animals. There were 18 plant species and 7 animal species eaten by sailfin lizards. Codiaeum variegatum, which had the largest canopy cover area, was the most prevalent species of forage plant. In general, it is also relatively abundant for animal feed. Ficus hispida and Davalia trichomanoides are the two forage plant species that are most frequently consumed out of the total of 18. One species, the river crab (Gecarcinucoidea), was the only one of the seven species of animal source that was frequently consumed. Key words: Sailfin lizard, Hydrosaurus, feeding ecology

Abstract

Due to the absence of topsoil, low pH, and contamination by various heavy metals, revegetation of post-nickel mining land, which is generally carried out by planting economically valuable species, is usually unsuccessful. This study aims to identify tree species suitable for revegetation on post-nickel mining land in Kolaka Regency, Indonesia. Nine plots measuring 20 m x 20 m were distributed in the revegetated post-nickel mining land at three different age categories (1, 5, and 10 years) to observe the growth of revegetation trees, which are introduced species and native tree species that naturally invade the revegetation area. In total, there were 24 tree species found in the revegetated post-nickel mining land consisting of 9 introduced revegetation species and the other 15 tree species were native tree species that invaded the revegetated area. The older the age of the revegetation, the more native plant species are found. In line with the increasing age of revegetation, the density of revegetation plants decreases while the density of native plants increases. The population structure of revegetation trees does not indicate that the species can regenerate, while the inverted shape of the population structure of native plants indicates excellent regeneration potential. Thus, the results of this study recommend making native species, including Buchanania arborescens, Alstonia macrophylla, Ficus sp. Syzygium sp. Colona scabra, Litsea sp., and Metrosideros cf. petiolata as revegetation plants in former nickel mining areas.

Abstract

Climatic elements are limiting factors for plants; therefore, climate change can impact the phenology of plants. This study aims to determine the impact of climate change on the reproductive phenology of four local mango cultivars on Sulawesi Island, Indonesia. Data were collected during 2013 and 2014 by observing and recording the production of vegetative shoots, generative shoots, and fruits from the trees of each mango cultivar weekly. To assess the impact of seasonal change on fruit quality, the weight and sugar level of the ripe fruits in each cultivar were measured. Climate data were obtained from the National Centers for Environmental Prediction and the Indonesian Agency for Meteorology, Climatology, and Geophysics Region IV, Makassar. Results show that from 1979 until 2014, the climate in the study site changed from type D to type C according to the Schmidt-Ferguson Climate Classification method, indicating that the wet season became longer. Following climate change, the reproductive phenology of the four mango cultivars also changed from once to twice annually, whereby the flush of vegetative and reproductive shoots that appeared during the first period in March did not successfully develop into mature fruit but developed following the second period in July. The change of season also impacted the quality of the mangoes, as fruit produced during the longer dry season had higher sugar levels than those produced during the shorter dry season.
