Assessing Avian Richness and Diversity in Different Regions of Oil Palm Plantation in Selangor, Malaysia

Abstract

ABSTRACT.Malaysia is characterized by a variety of habitats such as forests, clearings, thickets, and cropland that attract various species of birds. This study examined the bird community in terms of richness and diversity at oil palm plantations habitat. The abundance of birds was determined by using distance sampling point count method. A total of 2722 birds belonging to 38 families representing 86 species of birds were detected. Diversity analysis indicates that the species of birds in the oil palm plantation at Sungai Pelek is more diverse (Shannon-Wiener Diversity Index H; 3.52) and richness (Margalef's Richness Index R1; 10.2) than oil palm plantation in Teluk Panglima Garang-Pulau Carey and Banting-Jenjarum. However, the species of birds in the oil palm plantations at Teluk Panglima Garang-Pulau Carey and Banting-Jenjarum show higher evenness (Pielou's Evenness Index E; 0.82) compared with oil palm plantations in Sungai Pelek. The results of this study indicate that the species composition and distribution of the avian species in the oil palm plantations are affected by habitat characterization of that particular area and its vicinity.

Identifying the main drivers of change of phytoplankton community structure and gross primary productivity in a river-lake system

“…Shannon-Wiener Index (H') (Tian et al, 2017), Simpson Diversity Index (D S ) (McLaughlin et al, 2016), Marglef Richness Index (D M ), and Pielou Evenness Index (J) (Amir et al, 2015) were as a dependent variable to represent phytoplankton diversity and their calculation methods as Table S1. Phytoplankton diversity, species and environmental factors were analyzed using Origin (version 9.1).…”
