Abstract

Weaver ants Oecophylla smaragdina are social insects that recognize nestmates using pheromone. This study analyzes the feeding behavior and nestmate recognition of weaver ants in the urban area of three different islands (Sumatra: Baturaja; Java: Banyuwangi; Papua: Sorong). The free ants were placed in the arena composed of chicken meat, sugar, bananas as the baits. Ten trapped ants were also located in the arena to explore the nestmate recognition between the free and the trapped ants. Five types of behaviors, i.e., approach, stalking, communication, competition, and agonistic, were recorded in 6 days. Food preferences were indicated by the number of conduct towards the feeding sites, and nestmate recognition was indicated by approaching the trapped nestmate. The results showed that the percentage of the approach behavior of free ants was the highest in the three islands but had no significant difference between Sumatra and Java and between Java and Sorong (p-value >0.05). However, the study showed significant differences for the other four behaviors observed. As predicted, the percentage of chicken meat foraged by the ants was the highest due to the carnivorous behavior. The free ants showed the nestmate recognition to the trapped ants in all behavior, except competition.

Abstract

Epiphytic ferns can be found in host trees from the Angiosperm and Gymnosperm groups. Epiphytic ferns in Angiosperm plants host have been widely studied, but there is little known for Gymnosperm plants host. The aim of this study was to identify the species of epiphytic ferns in the Gymnosperm plants host at Cibodas Botanical Garden and to analyze the diversity of epiphytic ferns based on microclimate conditions and the surface texture of Gymnosperms plants host. Epiphytic ferns diversity data was obtained using purposive random sampling method. Factors that influence the occupancy of ferns are analyzed using Principal Component Analysis. Epiphytic ferns in Gymnosperm host at Cibodas Botanical Garden were identified as 18 species including 7 family. The most dominant species of epiphytic fern is Davallia denticulata (59.45%). Diversity of epiphytic fern on Gymnosperm at Cibodas Botanical Garden is moderate (H’ = 1.81).

Abstract

Leea angulata is a commonly plant used by the Sasak people as a medicine to heal the wounds, but the effects of L. angulata on wound healing process has not been studied. The aim of this research are to determine the effects of L. angulata bark extracts on wound healing of mouse skin and its influence on the localization of FGF2. 1% of L. angulata bark extracts (P1%) on day 7 can accelerate wound closure amounted at 94.66%, Deep and Superficial Contraction Index of 0.96 and 0.1, epidermis Index and remodeling index of 1.55 and 0.81. L. angulata bark extracts stimulates the synthesis of FGF2 early (3rd day ) compared to the postive control group (5th day). FGF2 in P1% group wa found in epithelial cells in the hair follicles, fibroblasts cell in granulation tissue and epithelial cells in the epidermis. In the positive control group FGF2 was found in in epithelial cell of hair follicle, while in the negative control group, FGF2 undetectable. FGF2 in P1% group detected earlier than the positive control, showing the process of proliferation in P1% accelerated. The results confirm the L. angulata bark extracts accelerate the wound healing in proliferation phase and influence localization of FGF2 in the wound area.

Abstract

Water availability in Mount Ciremai National Parks (MCNP) is influenced by sustainability of the vegetation. Therefore, tree regeneration around the water springs area needs to be investigated to maintain the sustainability of water springs ecosystem in the future. The purpose of this study was to analyzed and identify natural seedlings of tree regeneration around the water springs area Seda Block MCNP. The collections of vegetation and abiotic data was carried out on 9 sample plots measuring 3 m × 3 m which is purposively placed around water springs. Result show that vegetation in water springs dominate by seedlings Ficus sp., Ficus hemsleyana, and Trevesia sundaica. Shannon-Weiner diversity index in this location was moderate, but evenness and dominance index classified as high and low, respectively. Overall, seedling of trees dominated by orthodox seed-type and shade tolerant plant. The vegetation in this study dominated by plants categorized least concern (LC) based on IUCN red list. Microclimatic of study site affects 58.89% on abundance and distribution of tree seedlings. Therefore, the springs are in the Seda Block MCNP needs to be conserved and maintain its natural vegetation. Keywords: Mount Ciremai National Park, eco-hydrology, canonical correspondent analysis, conservation
