High rate of deforestation occurred in Sumatra Islands had been allegedly triggered by various factors. This study examined how the pattern was related to typology area, as well is being affected many factors such physical, biological, and socio-economic local community. The objective this formulate a spatial model based on triggering within each Islands. classes were developed basis using standardized-euclidean distance measure memberships cluster determined furthest neighbor method....

Mangrove forests play an important role in coastal areas from ecological perspective, being able to store large amounts of carbon through sequestration and inhibiting climate change processes by absorbing CO2 the atmosphere. In recent years, there have been changes land cover converted degraded mangrove which resulted release imbalance soil structure, turn cause a flux into This research was conducted at Karang Gading Langkat Timur Laut Wildlife Reserve (KGLTLWR) North Sumatra, Indonesia....

Molecular cloning of five oxidosqualene cyclases (OSC) genes from Bruguiera gymnorrhiza, Kandelia candel, and Rhizophora stylosa had previously been cloned, characterized, encoded mono -multi triterpene synthases. The present study analyzed protein modelling synthase mangrove using Phyre2 Swiss-model. diversity was noted within synthases sequence identity (38-43%) residue (696-703). RsM2 distinguishable others for template structure; it used lanosterol as a (PDB ID: w6j.1.A). By contrast,...

Mangrove forests are highly productive ecosystems that sustain marine life, including fish communities. This study aimed to analyse mangrove characteristics, physicochemical parameters, nutrient and primary production derived from litter estimate the production.
