Abstract:
Persawahan merupakan habitat yang baik bagi kehidupan amphibi. Amphibi memiliki fungsi ekologis sebagai penyeimbang ekosistem dan sebagai bioindikator lingkungan. Penilitian ini bertujuan untuk menganalisis keanekaragaman amphibi di areal persawahan Boleuvard Kota Tondano berdasarkan nilai indeks Shannon-Wiener. Penelitian ini menggunakan metode Line Transect yang dilaksanakan pada bulan Januari-Desember 2018. Nilai indeks keanekaragaman Shannon-Wiener pada transek satu H’ 0,782, transek dua H’1,208 dan transek tiga H’ 1,139. Berdasarkanhasilpenelitianterdapat lima spesies yang ditemukanya itu

Abstract:
Phytoplankton is the significant formal natural occupier of all water bodies. They play an important role in the biosynthesis of organic material. Being an index of trophic status phytoplankton reflects the overall environmental condition of the system and its potentiality. Present investigation was carried out for a period of twenty four month to study the diversity indices. Simpson’s Index of Dominance ranged from 0.0441 to 0.0952. Shannon-Wiener Diversity (H) index ranged from 2.6298 to 3.2112.273. Evenness Index ranged from 0.5593 to 0.9808 during the study period. Keywords: Diversity inde

The waters surrounding Ambon Island is a potential fishing gound for demersal fish resources, yet information regarding species diversity is still slightly understood. This research aimed to analyze the diversity of species and size of demersal fish around Ambon Island oceans. Data was collected based on experimental fishing using fish trap at two locations, in northern and southern waters of Ambon Island. The data were collected by experimental capture using fishing gear at two locations, namely northern waters (March-April 2015) and south of Ambon Island (July-October 2016). Methods of demer

Abstract:
An understanding of soil moisture variation patterns under different plant community structures is crucial for the restoration of vegetation in southern China karst regions. Therefore, four plant community structure types: arbor + herb (AH), shrub + herb (SH), arbor + shrub + herb (ASH), and herb (H), were selected as the research objects. A soil moisture sensor was used to monitor the soil moisture content in the 0–70 cm soil layer, to analyze the variation characteristics of soil moisture content and to explore the differences under different plant community structure types.

Insect diversity is believed to be used as a bio-indicator of spring quality, this study aimed at determining the spring insect diversity around the Mutis Timau Nature Reserve. The study was conducted from June to August 2019. Insects were caught by using the yellow pan trap and hand sorting. The diversity of spring insects was determined based on the Shannon-Wiener diversity index (H'), species richness index (R1), species dominance index (D), and evenness index (E). The results showed that 16 species belong to 11 families, and five orders of insects. The families included Gryllidae, Gryllota

In Central Mexico converge three biogeographic provinces: Altiplano sur, Sierra Madre Occidental and Costa del Pacífico. Each one of them is composed by different plant communities: Thorn Forest, Temperate Mountain Forest and Dry Tropical Forest respectively. Our objective is to show, through phytoecological analysis, the species richness, diversity and the structure of the plant communities from the Temperate Mountain Forest and from the Tropical Dry Forest.

Throughout the previous chapters, we have focused on our understanding of the benthic system, its processes, structure, and functioning but, hopefully, we have also shown some of the changes to the system as the result of human activities. It is now relevant to look at the way in which management relies on and uses benthic data and information, the way in which benthic information and data are put into a wider context, and the way we manage marine sediments. Although examples in this chapter are mainly taken from European initiatives, the same examples exist in other regions. In all countries,
