Abstract

The diversity of mangrove species in an area can be observed through morphological structure, anatomy, as well as palynology. Palynology is a study of pollen that frequently used as a reference to support data in identifying mangrove species. Mangrove areas in Bali have patchy distribution, one of which can be found in the Batu Lumbang area. Batu Lumbang is a mangrove area that is part of the Ngurah Rai Forest Park. Observation of the micromorphological characteristics of pollen in the Batu Lumbang mangrove forest area was carried out through the acetolysis method with modification. Eleven mangrove species were sampled, comprised of Aegiceras corniculatum, Avicennia marina, Bruguiera gymnorhiza, Ceriops tagal, Exoecaria agallocha, Lumnitzera racemosa, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Sonneratia caseolaris, and Xylocarpus granatum. The results of observations on pollen from eleven species of mangroves show similarities of pollennits, monads. In addition, other pollen characters such as aperture type, pollen shape, and pollen size categories found vary among the samples observed. These characters can also group several species that have the same family or genus. In turns, these can be used as diagnostic character to distinguish one species with another.

Abstract

Birds are an important component of balancing ecosystems and have a reciprocal relationship and close dependence to their environment. The high number of bird species found can indicate the ecological role of the environment, either for finding food and shelter, or for nesting and breeding areas. Udayana University Bukit Jimbaran Campus, with a total land area of ??27,649 ha, still has plenty of green area. This condition provides great potential as habitat for various bird species. This study aims to identify the bird species found in Udayana University Bukit Jimbaran campus area. The method used was the point count method at 11 observation points that was determined by purposive sampling. The indices calculated were the diversity, uniformity, dominance, and relative abundance. From this study, 30 bird species from 18 families were recorded with a total of 571 individuals scattered at each observation point. Based on the calculated indices, the diversity of bird species in Bukit Jimbaran Udayana University campus area was considered as moderate, with a stable species distribution, and low dominance (no species dominates). Keywords: abundance, birds, diversity, dominance, evenness
