Abstract

Research has been carried out to determine the cell structure of the epidermis and stomata in some mangrove plants in the species Aegiceras corniculatum and Rhizophora apiculata. Descriptive method is used to describe the cell structure of the epidermis and stomata of Aegiceras corniculatum and Rhizophora apiculata and quantitative leaves to calculate the number of stomata, number of epidermis and stomata index based on nail polish on the cross section of epidermal cells on the lower underside of the leaf using a light microscope, while the incision longitudinal to determine leaf thickness between the upper epidermis and the lower epidermis. The results showed that the two mangrove species that grow in the mouth of the Poka and Leahari villages namely Aegiceras corniculatum and Rhizophora apiculata were found to have the same anatomical structure and leaf anatomical characteristics in terms of the shape of epidermal cells, rectangular, octagonal, elongated, and irregular. Aegiceras corniculatum and Rhizophora apiculata have anomositic stomata type because neighboring cells surround the stomata and have the same shape as epidermal cells. Mangrove species in the river estuary of Poka Village have higher number of stomata and smaller epidermal size and lower stomata index than mangrove species in Leahari Village due to the influence of the shade. Keywords: Aegiceras corniculatum, Rhizophora apiculata, Epidermal cells,

Abstract

The conservation area of Pombo Island is the path of migratory shorebirds. Nowadays, the rate of damage to forest and coastal ecosystems in the conservation area of Pombo Island is thought to have an effect on the presence of water birds. This study aims to map the distribution of waterbirds on Pombo Island, Central Maluku Regency. This study uses a combination method between the point count method (Point Count). The distance used in this study was 20 m. The time period for counting the number of individual birds at each counting point is set at 10 minutes. Transfers between counting points, which are 20 m apart, take about 30 minutes. The coordinates of each bird watching point were recorded using a GPS tool to determine the geographic distribution of waterbirds in the conservation area of Pombo Island. Furthermore, the results of the coordinates of the GPS device are used to map waterbirds in the studied locations. The results obtained were four species of water birds, namely the Coast Trinil (Actitis hypoleucos), Swamp Trinil (Tringa stagnatilis), Bush Trinil (Tringa glareola) and Little Egret (Egretta garzetta) with random distribution patterns. Keywords: Waterbirds, GIS, Distribution, Conservation area, Pombo Island
