The balance of the ecosystem in a location is certainly related to the food-eating process that occurs in it. This long process is naturally used by natural organisms to flow the energy cycle chains that exist in each individual. The condition of habitat balance can be identified by the structure of bird guilds in an ecosystem. Quiet curly tourism area has a unified landscape landscape in the form of modified secondary forest. This is indicated by the presence of canopy cover that is no longer dense and modified by human activities. The location of the study this time was carried out in several locations of quiet curup tourist areas, namely in the parking lot and its surroundings, the biodiversity park of Bedegung and its surroundings, the curup waterfalls of calm and surrounding areas. The study was conducted on 6-8 August 2019. Field findings found eight types of bird guilds, namely insectivores, frugivores, carnivores, omnivores, granivores, piscivores, insectivores, frugivores and nectinivores. Most guild members found were insectivores with 43 species of members. The structure of food network pyramids that can be compiled from the results of the study are granivores and frugivores, and pure carnivores occupy the top rank with members of 3 species. Pure carnivore is a top predator in this quiet, steep landscape. Its existence is very important to control the guild population that is below it. So that the balance of the ecosystem in this location can be seen from the benchmarks of the existence of this pure carnivore type.

Abstract The purpose of this study was to determine the habitat characteristics of the Sumatran Elephant in the Serbajadi District Forest. Data collection by looking at the use of habitat which is characterized by the distribution of faeces found in various habitat units in the home range of the Sumatran Elephant. The method used is observation with a track with a size of 3,600 m which is divided into 20 observation plots with a distance between plots of 100 m. The data obtained in the field were analyzed descriptively and presented in tabular form. The results of this study indicate that the Habitat Characteristics of the Sumatran Elephant in the Serbajadi District Forest chose habitat units with very dense canopy cover (>75%), moderate feed availability (26-50%), rare mineral source trees availability (< 3 trees/plot). availability of sparse scrubbing trees (<3 trees/plot), close to primary forest (0-500 m), low land elevation (0- 400 masl), gentle slope (0-20°), close to water sources (0-250m). Secondary forest/vegetation type and frequency of habitat use based on the findings of faeces that the Sumatran elephant most frequently visited was secondary forest than primary forest because the secondary forest was for feeding activities while the primary forest was used for resting and reproduction.

Aim: This study aimed to assess the spatial and seasonal variation of the water quality and physical habitat characteristics along the upper-middle stretch of the Paraitinga River, a tributary of Tietê River, considering the potential influence of different riparian conditions along the stretch studied.MethodsSixteen sites with different riparian vegetation, including native forest, secondary forest, pasture, and eucalyptus were sampled during the dry and rainy seasons of 2004/2005, before the damming of the Paraitinga Reservoir. Several physicochemical and habitat parameters were determined and data analyzed in relation to spatial distribution and potential influence of riparian conditions.ResultsWater quality parameters were in general within the limits established by CONAMA for Class 2 waters, except for turbidity and total phosphorus. There were seasonal and spatial differences in the limnological parameters along the stretch studied and apparently they were related to point specific influences associated with land use and canopy cover. Habitat characteristics were markedly different between the upper and middle river stretches, especially in relation to depth, width, substrate and canopy cover.ConclusionsAlthough a direct influence on the observed variables could not be attributed solely to the riparian vegetation, vegetation cover seemed to affect particular stream characteristics. Open pasture and eucalyptus sites were subject to point specific effects that caused phosphorus inputs and higher turbidity and temperature, and showed different morphological features, suggesting that land use at the sub-watershed scale was an important factor affecting stream conditions.

Amphibians are an integral part of the ecosystem and act as an ecological indicator.  As several species are added to the list of threatened species every year due to loss of habitat, it is important to understand the role of unmanaged landscape for sustenance of amphibian diversity.  In this study, 28 amphibian species were recorded from different modified habitat including 19 new records for Dampa Tiger Reserve (DTR) and its surrounding areas.  Further, six species, Amolops indoburmanensis, Limnonectes khasianus, Microhyla mukhlesuri, M. mymensinghensis, Raorchestes rezakhani, and Sylvirana lacrima are new distribution records for the state of Mizoram and out of these, two species, Raorchestes rezakhani and Sylvirana lacrima, are new country records for India.  Amongst the recorded species, four species are Data Deficient, two Vulnerable, 14 Least Concern, and eight species are not assessed as per the IUCN Red List.  Within the core and buffer areas of DTR, we found that natural perennial stream, puddles, canals, natural ponds, fish ponds, roadside, primary forest, secondary forest, paddy fields, and human settlement areas are excellent microhabitats for amphibian population and need to be conserved for their rich ecological niches.

Abstract Increase of human activities on coastal area in Central Weda Sub-District has caused degradation of coastal ecosystems. Even though coastal ecosystems have an essential role in marine ecology, such as coral reefs and mangrove forests, they are sometimes undermined by economic or commercial interests. This study aimed to determine density and cover percentage of mangrove forests and coral reefs in Central Weda Sub-district, North Maluku. Data collection on coral reef ecosystem components was carried out by applying georeferenced photo-transect and line transect quadrat techniques. While for mangroves, data collection included species diversity and tree/canopy cover percentage. Study result showed that based on lifeform percentage of coral reefs, most of the study areas were in a good category with 23.95% coverage, moderate condition 39,5%, and poor condition 36.6%. The coral reefs in good and moderate conditions were found at location having relatively low human activities. Whereas percentage of mangrove cover from all stations ranged from 78,39 to 78,76% with Important Value Index ranging from 106,79% to 158,32%.

Abstract Background Performing forest inventory in the campus is one of the breakthroughs towards achieving sustainable campus. The inventory aims to determine the number of trees and calculate the stocking of carbon and biomass. This is inevitably important when the contribution of trees to the oxygen supplies as well as stocks for carbon biomass are of concern. Realising the importance of contribution of trees to the surrounding community, this study was therefore conducted. Results The study area is identified as secondary type forest with 50.1% of the strata is 60–80% canopy cover dominated by small stands. There is a total of 14 sampling plots inventoried and measured using 40 x 40m square plot sampling. 41% of the three species found comprised of rubber trees (Hevea Brasiliensis). The total number of trees estimated is 97,325 trees with the average density of 21 m2/ha and 24,146.54 Mg CO2e aboveground biomass and carbon stocking. Conclusion The study has successfully assessed the forest resources that are available in University Malaya campus. It was found that the forests in the study area fall in the category of secondary forest where stands are in the successive growing stages. Intensive sampling units with support from sufficient spatial data produced reliable estimates. This information is crucial for the reporting of forest resources that reside in an urban environment. With the new sets of data of the forest obtained from the forest inventory, UM management now have the ability to easily and accurately evaluate the composition and condition of the forest, and estimate the environmental services and aesthetic values. These are the first few steps that have been taken by UM towards improving the management of the urban forest on campus.

The vegetation at Muong Nhe nature reserve has been described in 5 types: Tropical evergreen moist monsoon closed forest (only secondary sub-types formed by human activities including tropical evergreen moist monsoon secondary forests after selected logging, tropical evergreen moist monsoon secondary forests formed on abandoned upland fields, tropical evergreen secondary scrubs and grasslands); Tropical semi-evergreen semi-dry monsoon closed forest (only secondary sub-type formed by human activities); Sub-tropical evergreen moist monsoon closed forest (including secondary sub-types formed by human activities including sub-tropical evergreen moist monsoon secondary forest and sub-tropical evergreen secondary scrubs); Sub-tropical evergreen moist monsoon broad-leaved mixed with conifers forest; Sub-tropical semi-dry monsoon deciduous forest (only secondary sub-types formed by human activities including sub-tropical semi-dry monsoon deciduous secondary forest after selected logging, sub-tropical semi-dry monsoon deciduous secondary forest formed on abandoned upland fields, sub-tropical semi-dry secondary scrubs and grasslands) and cultivated communities. The results showed that closed forest is located at sub-tropical zone only. Based on species existed in each forest sub-type or community, the abundant species in tropical zone are fast-growing and photophilic plants while the abundant species in sub-tropical zone include both  fast-growing plants and typical sub-tropical plants with monsoon moi climate or monsoon semi-dry climate. In the winter, tropical semi-evergreen forest and sub-tropical deciduous forest forms to North-Western regionalism. The non fast-growing and photophilic species are expected to be most abundant in the future based on currently vegetation succession indication, and there will be more and more closed forests in the near future at Muong Nhe nature reserve.  


“We regard the recent science –based consensual reports that climate change is, to a large extend, caused by human activities that emit green houses as tenable, Such activities range from air traffic, with a global reach over industrial belts and urban conglomerations to local small, scale energy use for heating homes and mowing lawns. This means that effective climate strategies inevitably also require action all the way from global to local levels. Since the majority of those activities originate at the local level and involve individual action, however, climate strategies must literally begin at home to hit home.”
