Abstract

Point Quarter Method is a plant community structure measurement procedure. The technique is base on measurement of distance of four plants or trees in every  quarter  that is made by four space in the cross line sampling field studies. In forest sampling, point centered quarter methods is considered as the efficient, reliable and accurate data,  not only for mean distance and density, but for frequency and dominance of species. So it is important to try wether these method ould be applicated to animal, especially crab. These method was applicated for crab population in Padang Beach at December 22nd, 2014.  Ten points quartered were made and the distance of every Ocypode sp crab burrow was counted by ruler. Mean distance of crabs burrow gained by divided of total number of quarter (20) with  mean distance of every burrow to the point. Density per hectare is 10,000 m divided by quadratic of mean distance. Mean distance of burrow to points were counted and prediction of population per hectare could be found. In these case, mean distance was: 0.41 m and crab population  is :59,488.34 individu per hectare. Compared to other species , eg Scylla serrata, its population is bigger, eventhough the condition of beach is polluted and wastedKeywords: point centered quarter method, Ocypode sp, density

Abstract

The research was conducted at four stations in the Omuta-gawa River, Kyushu, Japan from December 2003 to July 2005. The results of the monthly survey clearly indicated that Hediste japonica has one generation per year. The reproductive period of this species is from late December to late February, and also occurred on H. diaroma, that it has one generation per year. The reproductive period of this species in the Omuta-gawa River is from middle December to late April, when reproductive swarming of mature adults occurs. This reproductive period is much longer than that of H. japonica. Both Hediste species, spawning, fertilization and early development occur in water column with a long pelagic larval life. Keywords: life history, Hediste japonica, H. diadroma, reproductive period, estuary

Abstract

The research was conducted to inventory and identify as well as acknowledge the correlation between vegetation type with soil arthropods in the Green Barrier area of PT Pusri. PT. Pusri green Barrier area is 28 hectares and dominated by 10 types of vegetation, such as, the Angsana (Pterocarpus indicus Wild), Bambu (Bambusa Sp), Beringin (Ficus benyamina), Buah Roda (Hura crepitans L), Jati (Tectona grandis L), Kelampayan (Neolamarckia cadamba) , Ketapang (Terminalia catappa L), Mahony (Swietenia macrophylla King), Pulai (Alstonia scholaris), and Sengon (Paraserianthes falcataria L). Soil arthropods were collected by using pit fall traps and funnel barlese-tullgren in every type of vegetation, between July-August 2015. Identification of arthropod genera Identification has been done in Entomology Laboratory of the Agriculture Plant Disease Faculty Sriwijaya University, and analysis of soil organic in the Laboratory of Soil Faculty of Agriculture Sriwijaya University. The results were obtained into 3 classes of soil arthropods belonging to the 10 orders, 28 families and 35 genera. The diversity index value of soil arthropods in various types of vegetation is classified moderately (H= 1-3), and no type of soil arthropods were dominant, mean that soil arthropods with different types spread over in the various types of vegetation in the area of Green Barrier PT. Pusri. Light intensity abiotic factors play an important role in the life of the soil arthropod communities in vegetation Sengon (Paraserianthes falcataria L) with a correlation coefficient 1.00Keywords: soil arthropods, community structure, a biotic factors, Green Barrier PT.

Abstract

The study was conducted to determine birds in Green Barrier PT. Pusri and explains the function of the existing vegetation in the Green Barrier for many species of birds. Retrieval of data was conducted in a 28 ha Green barrier area of PT Pusri, during July to August 2015. The collecting of data determined by line transects through observation directly. assuming the selection of sites in the area of water resources and representation of vegetation types that represent a potential habitat for birds. Birds observed then identified and recorded the type, activity include, nesting, feeding, perch and plants that exploited. The results of this study found 17 species in 13 families. Plant species are most frequently used by birds is batai wood (Paraserianthes falcataria). Recorded at least 10 species of birds found in the Green Barrier PT. Pusri utilize these plants as a perch, feeding and nesting. The availability of water in the form of an artificial fish ponds at the fish pond 1 (transect 3) to attract water birds such as; Javan Pond-heron (Ardeola spesiosa) and Common Sandpipers (Tringa hypoleeucos) to come looking for food that needs to be managed to maintain its function as a habitat for birds.Keywords: Birds, plant, habitat, Green Barrier PT.
