Community of Mangrove Category Tree and Sapling in The Sekotong Bay, West Lombok

Community of mangrove in the Bay of Sekotong, West Lombok was studied to know the species composition, individual density of each species, and percentage covering of mangrove canopy. Total 28 plots of 10 m x 10 m were set in 9 transects in 5 stations. Photographs of canopy covering and mangrove community composition were analyzed by using software ImageJ and template spreadsheet 10x10, the new version of March 2018. The community of mangrove of Sekotong bay, West Lombok consists of 8 species, 5 genera, and 4 families. Rhizophora apiculata & Rhizophora stylosa were recorded in seven of nine transects (78% of transect). Ceriops tagal was a species that was also recorded to have the highest density (3700 trees/ha) in transect SKTM02B. The average density of the mangrove sapling category was higher than the mangrove tree category. The three highest covering percentages of canopi mangrove community took place in transects SKTM01A, SKTM01B, and SKTM04T.

ANALISIS KOMUNITAS MANGROVE DI KECAMATAN SEKOTONG LOMBOK BARAT NTB

Abstrak:Komunitas mangrove di kawasan Sekotong Lombok Barat telah diteliti untuk mengetahui komposisi spesies, kerapatan individu setiap spesies,dan persentase tutupannya. Total sebanyak 28 plot (kudrat) berukuran 10m x 10m dibuat pada 9 transek di lima stasiun. Foto tutupan kanopi mangrove dan parameter komposisi komunitas dianalisis menggunakan software ImageJ dan template spreadsheet. Data kerapatan pohon dan persentase tutupan mangrove dianalisis dengan ANOVA. Persentase kesamaan antara stasiun menggunakan Biodiversity Program Version 2 berdasarkan the Bray Curtis Cluster Analysis. Komunitas mangrove di Kecamatan Sekotong Lombok Barat teridenfikasi 8 spesies, meliputi 5 genus, dan 4 famili. Rhizophora apiculata tersebar disemua transek penelitian. Transek SKTM02B memiliki kerapatan pohon tertinggi sebesar 2800 pohon/ha. Tiga transek dengan persentase tutupan tertinggi berturut-turut SKTM04T, SKTM04, dan SKTM01A. Persentase kesamaan antar stasiun sangat tinggi mencapai 82,503 – 95,423%. Persentase kesamaan tertinggi (95,423%) terjadi antara stasium SKTM04 dan SKTM05.

Photographs mangrove canopy covering and parameter of mangrove community composition were analyzed by using the software ImageJ and template spreadsheet. ANOVA was applied for analyzing the data of mangrove tree density and percentage covering. The Bray Curtis Cluster Analysis. using Biodiversity Program Version 2 was also used for analyzing the percentage similarity among station. The community of mangrove of Sekotong West Lombok consists of 8 species, 5 genera, dan 4 family. Rhizophora apiculata was recorded in all transects. The highest density (2800 trees/ha) of mangrove was recorde in ransect SKTM02B.. The three transects with the highest percentage covering were SKTM04T, SKTM04, dan SKTM01A, respectively. Percentages similarity among station were very high (82,503% – 95,423%). SKTM04 and SKTM05 were the two station with the highest percentage similarity (95,423%).

Komunitas Mangrove di Wilayah Pesisir Pulau Tidore dan Sekitarnya

<strong>Mangrove Community in Coastal Area of Tidore Islands.</strong> Indonesia has the most extensive area of mangrove ecosystem in the world. It bring many direct and indirect benefits for the coastal community. Research on the condition of mangrove communities in Tidore, Halmahera, Ternate Island and surrounding areas was conducted in August 2015, to determine the current condition of mangrove communities in the region. Assessment condition mangrove forest was done by means of analyze the percentage covering canopy with the hemispherical photography methods (photography toward) vertical and analyze the percentage pixels from a photograph obtained by using software image J and Microsoft Excel. The species Sonneratia alba in the Maitara, Tidore, and Kaiyasa Island West Halmahera is the most dominant.

El presente estudio el cual surge del censo realizado por primera vez en Cartagena en el año 2005 indica que el 11.2% de la comunidad no tiene ningún nivel educativo, porcentaje que abarca los barrios aledaños a la Ciénaga de la Virgen como son: el Pozón, “Olaya herrera”, Fredonia y Nuevo Paraíso y en segunda instancia, porque el barrio Olaya Herrera se encuentra el Sector Rafael Núñez zona de influencia de la Corporación Universitaria Rafael Núñez, aspecto que llevó a la coordinadora de prácticas pedagógicas investigativas, a estructurar y realizar este trabajo con estudiantes de los programas de licenciatura en Pedagogía Infantil y Educación Especial como parte de las actividades de la proyección universitaria a la comunidadABSTRACTThe present study, which arises from the first census in Cartagena in 2005 indicates that 11.2% of the community does not have any education, percentage covering neighborhoods surrounding the Cienaga de la Virgen as: the Pozón "Olaya Herrera", Fredonia and New Paradise and secondly, because the neighborhood is Olaya Herrera.Rafael Nunez Sector area of influence of the University Corporation Rafael Nunez, something that led to the coordinator of investigative teaching practices, to structure and perform this working with students in degree programs in Early Childhood Education and Special Education as part of the screening activities to the community college.

Influence of Palythoa caribaeorum (Anthozoa, Cnidaria) zonation on site-attached reef fishes

This work aimed to test the influence of Palythoa caribeorum, a widely distributed zoanthid in the Atlantic, on site-attached reef fish in a subtropical rocky shore. Density, richness and vertical distribution of reef fish inside (ID) and outside (OD) previously chosen P. caribaeorum dominance patches were compared through stationary visual censuses along three different periods. Fishes were grouped in different trophic guilds to evidence differences in resources uses in both treatments. A complexity index was estimated by the chain link method and percentage covering of benthic organisms was obtained analyzing random points from replicated photo-quadrats. We observed thirty-eight species of fishes, belonging to twenty-five families. Reef fish communities between studied patches were similar,both in terms of species composition and vertical distribution. Considering only the most site-attached fishes, which were the most frequent and abundant species, data showed that ID sustains higher diversity and abundance than OD. Results showed that benthic composition differ significantly among patches whereas complexity remained without differences. Otherwise, results indicated that these areas might play an important role in space limitation, structuring neighboring benthic community and consequently reef fish assemblages.
