Effect of habitat transformation from grassland to Acacia mangium plantation on dung beetle assemblage in East Kalimantan, Indonesia

Abstract

Clean Development Mechanism afforestation often involves the creation of fast growing tree plantations on non-forest lands. To estimate the possible impacts of afforestation on the biodiversity of local species, we compared the diversity of dung beetles collected using baited pitfall traps placed in grasslands, plantations of Acacia mangium, and intact natural forests in East Kalimantan, Indonesia. The species richness in plantations was higher than that on grasslands but lower than that in intact natural forests. Ordination analysis revealed that the structures of beetle assemblages in plantations were intermediate between intact natural forests and grasslands. However, the indicator species for the intact natural forests were never or rarely seen in the plantations. These results suggest that afforestation increases the local native diversity of dung beetles but that plantations are not readily colonized by the indicators of intact natural forests. Conversely, it is suggested that afforestation decreases the abundances of two grassland specialists.

Primary forest loss and degradation reduces biodiversity and ecosystem functioning: A global meta‐analysis using dung beetles as an indicator taxon

“…Prospects in the top 10 countries with the most area of forestry plantations (see Payn et al, 2015) are expected to be even more harmful due to the increase in this type of vegetation cover, including Indonesia (associated with the Wallacea hotspot), Thailand and Vietnam (related to the Sundaland hotspot). Given this situation, South‐eastern Asia, Oceania and South America can be considered as extremely vulnerable regions due to the growing threat that primary forests experience regarding the increase in exotic plantations and its consequent negative effect on tropical dung beetles (see Beiroz et al, 2016; Gardner et al, 2008; Ueda et al, 2015).…”

Effects of human‐dominated landscape on the community structure of silphid and dung beetles collected by carrion pitfall traps

“…Factors affecting the community structure of carrion beetles are reported to be the age of the forest (Ueda 2016), light intensity of the forest floor (Ueda et al . 2015), and forest management such as logging (Scheffler 2005). Such factors may have been different between the two forest areas that were included in this study.…”

“…Following Ueda et al . (2015), the traps used were plastic cups about 9 cm wide and 14 cm in height. About 50 mL of propylene glycol (50–100% concentration) was used to preserve the captured insects without spoilage (Sugiura et al .…”

Kelimpahan Dan Kelimpahan Relatif Dung Beetle Di Hutan Pendidikan Konservasi Terpadu Universitas Lampung Pada Blok Lindung Tahura Wan Abdul Rachman

“…Tinja yang lembab memiliki aroma yang lebih menyengat dibandingkan tinja yang sudah kering. Menurut penelitian Ueda et al (2015); Aruchunnan et al (2016); Dewi et al (2017), apabila hutan telah mengalami kerusakan yang begitu parah seperti pengalihan fungsi lahan dari lahan tertutup menjadi lahan terbuka, maka tidak akan ditemukan spesies tersebut lagi. Hal ini karena dung beetle tidak menyukai cuaca yang panas.…”
