Index Of Diversity

Soil arthropod biodiversity was monitored in 24 olive orchards located in eight different sites in Messara, Crete, covering the two main agroecological zones of olive oil production, hilly and plain. Monitoring was done weekly for five weeks per season, from autumn 2011 to summer 2012, using pitfall traps. Subgroups of functional taxa were defined with respect to services of biological pest control and of nutrient cycling. Comparison of the different agroecological zones in terms of abundance and diversity of soil arthropods and functional subgroups was performed. Coleoptera (39.52%), Formicidae (27.3%), Araneae (8.77%) and Collembola (5.32%) were the most abundant taxa found in the olive orchards. Hilly orchards presented higher total arthropod diversity, but lower abundance due to family Tenebrionidae. Arthropod richness did not differ between agroecological zones. Functional arthropods were a major part of total abundance (76.7%) and presented a trend of higher catches abundance in the hilly orchards arthropods with seasonally statistically significant differences. Shannon Index of Diversity showed higher arthropod diversity in the hilly orchards, being significantly higher in spring. The less intensive olive production in hilly areas appeared to favour soil arthropod diversity.

Abundance And Diversity

Soil arthropods have role as herbivores, decomposers, predators and bioindicators of the various functions on ecosystems. Soil arthropods have an important role in increasing and maintaining soil productivity through the decomposition process of organic matter. The research was conducted to investigate abundance and diversity of soil arthropods in Manggis Natural Reserve and Coffee Agroforestry System. Hand-shorting methods and pitfall traps were used to catch soil arthropods. The abundance of soil arthropods were analyzed into diversity index. The result showed that the Natural Reserve has higher family number of soil arthropod and diversity index than the Agroforestry System. Individual of Hymenoptera order is very abundant in both location.

Soil Arthropod

Manggis Gadungan Natural Reserve is a biggest protected forest area in Kediri regency. There are many plants and animals conserved in the Natural Reserve. The main road crosses in the area was used as destination place. Since January 30, 2015 the road was unloaded. Soil arthropods have the ability to return to disturbed habitat. Soil arthropod diversity can illustrate the linkage of soil arthropod and ecosystem service. The research aims to compare abundance, composition and diversity of soil arthropod on the forest floor and ex-road in Manggis Gadungan Natural Reserve. The soil arthropods were collected by pitfall traps. The results show that there are 5 classes of soil arthropod i.e. Arachnida, Chilopoda, Collembola, Diplopoda and Insecta. The insect class has the highest taxa number of soil arthropods. The forest floor is characterized by the presence of Paronellidae 1, Entomobryidae 1 and Formicidae 5 while the ex-road is characterized by Paronellidae 2, Formicidae 1, Formicidae 7 and Gryllidae 1. The forest floor is dominated by decomposer while the ex-road is dominated by predator. Diversity of soil arthropod on the forest floor is higher than on the ex-road.

The Impact

Organic farming has been recommended by many experts in the world because of its positive ecological impacts such as increasing biodiversity. In Indonesia, the practice of organic farming is very widespread, including in smallholder coffee plantations. This study was intended to determine the impact of the organic farming system applied by smallholder coffee farmers for 2 years on soil arthropod diversity. On the two coffee farmlands, the conventional and organics (1 ha each), 10 plots of 5 x 20 meters were set and in each of these plots 5 sampling points were defined for collecting soil arthropods using pit-fall technique. The analysis of arthropod diversity in the two fields was quantified using the Shannon-Wiener diversity index model. The results showed that the two compared coffee farming systems had the same index of diversity (H ') and evenness (E). However, statistical tests using the Hutcheson t-test revealed that the variance in diversity of arthropods in organic coffee farms was significantly higher than in conventional ones (α <0.001). Therefore, it can be concluded that the practice of organic coffee farming, although in a short time, has been able and potent to increase the population and/or diversity of soil animals.

Abundance And Diversity

AbstractDespite enormous diversity, abundance and their role in ecosystem processes, little is known about how community structures of soil-inhabiting nematodes differ across elevation gradient. For this, soil nematode communities were investigated along an elevation gradient of 1000–2500 masl across a temperate vegetation in Banihal-Pass of Pir-Panjal mountain range. We aimed to determine how the elevation gradient affect the nematode community structure, diversity and contribution to belowground carbon assimilation in the form of metabolic footprint. Our results showed that total nematode abundance and the abundance of different trophic groups (fungivores, herbivores and omnivores) declined with the increase of elevation. Shannon index, generic richness and evenness index indicated that nematode communities were more diverse at lower elevations and declined significantly with increase in elevation. Nematode community showed a pattern of decline in overall metabolic footprint with the increase of elevation. Nematode abundance and diversity proved to be more sensitive to elevation induced changes as more abundant and diverse nematode assemblage are supported at lower elevations. Overall it appears nematode abundance, diversity and contribution to belowground carbon cycling is stronger at lower elevations and gradually keep declining towards higher elevations under temperate vegetation cover in Banihal-pass of Pir-Panjal mountain range.

Poplar plantations have the capacity to improve the properties of soils in muddy coastal areas; however, our understanding of the impacts of plantation development on soil arthropods remains limited. For this study, we determined the community dynamics of soil dwelling arthropods across poplar plantations of different ages (5-, 10-, and 21-years) over the course of one year in Eastern Coastal China. The total abundance of soil arthropods differed with stand development. Further, there were some interactions that involved the sampling date. On average, total abundance was highest in the 10-year-old stands and lowest in the 5-year-old stands. Total abundance exhibited strong age-dependent trends in June and September, but not in March or December. The abundance of Prostigmata and Oribatida increased in the 5- to 21-year-old stands, with the highest levels being in the 10-year-old stands. The abundance of Collembola increased with stand development; however, the stand age had no significant impact on the abundance of epedapic, hemiedaphic, and euedaphic Collembola. Order richness (Hill number q = 0) curve confidence intervals overlapped among three stand ages. Shannon and Simpson diversity (Hill numbers q = 1 and q = 2) differed between 10- and 21-year-old stand age. They showed almost similar trends, and the highest and lowest values were recorded in the 21- and 10-year-old stand ages, respectively. Permutational multivariate analysis of variance demonstrated that composition also varied significantly with the sampling date and stand age, and the 10-year-old stands that were sampled in June stood well-separated from the others. Indicator analysis revealed that Scolopendromorpha and Prostigmata were indicators in June for the 10-year-old stands, while Collembola were indicators for the 21-year-old stands sampled in September. Our results highlight that both stand development and climate seasonality can significantly impact soil arthropod community dynamics in the reclaimed coastal saline soils of managed poplar plantations.

Abstract. Haneda NF, Hilwan I, Irfani E. 2019. Arthropod community at different altitudes in Gunung Halimun-Salak National Park, Western Java, Indonesia. Biodiversitas 20: 1735-1742. Gunung Halimun Salak National Park (GHSNP) stores high biodiversity both from its flora and fauna. Parts of the diversity that have not been widely explored are soil arthropods at different altitudes. The aim of this study was to analyze soil arthropod community and the correlation between the attributes of soil arthropods and the environmental factors. The soil arthropods were collected using pitfall traps, placed in several altitudes, i.e., 500 m, 700 m, 900 m, 1100 m, 1300 m, 1500 m, and 1700 m . The attributes of community and environmental parameters were analyzed using Pearson correlation and principal component analysis. The result showed that family Formicidae dominated the soil arthropod community. The diversity of arthropods increased with increasing altitudes. The habitat at the altitudes of 1500 m, 1300 m and 1100 m had a dense canopy, thick litter and high total N and organic C. There was positive correlation between the attributes of soil arthropod community and environment variables.

Nutrient enrichment of Sawa lake water was made using different nitrogen and phosphorus concentrations during autumn and spring at three stations. Different concentrations of nitrogen, phosphorus and N: P ratios were used to test variations in phytoplankton population dynamics. Nitrogen at a concentration of 25 µmole.l-1 and N: P ratio of 10:1 gave highest phytoplankton cell number at all stations and seasons. A total of 64 algal taxa dominated by Bacillariophyceae followed by Cyanophyceae and Chlorophyceae were identified. The values of Shannon index of diversity were more than one in the studied stations.
