Respon Semut Terhadap Kerusakan Antropogenik Pada Hutan Lindung Sirimau, Ambon

Abstract

The objective of field study was to study the response of ants to forest damage due to presence of human activities in Sirimau Conservation forest, Ambon. The respons of ants was analyzed based on their richness, abundance, diversity, frequency and functional response to anthropogenic damage by used of line transecting method. Secondary parameters measured were local microclimate as well as soil physical and chemical characteristics. The study found 23 species of ants and 16,601 individual ants in the forests; the highest species abundance was 0.158, while frequency and diversity index was 32.44% and 2.92 each and were classified as moderate. Functionally ants consisted of oppurtunist (1 species), generalized myrmicinae (1 species), specialist predators (4 species), tropical climate specialists (6 species), dominant dolichoderinae (4 species), subordinate camponitini (6 species) and criptic species (4 species). Anthropogenic activity contributed to forest habitat destruction through forest opening, logging, forest fires and shifting cultivation. Anthropogenic damage in secondary forest caused fragmentation and degradation, followed by inbalance of environment and ecosystem components

Phytophagous insects and predatory arthropods in soybean and zinnia

“…In contrast, C. transversalis found both in soybeans and zinnia from the net trap method, and predator spiders found only in zinnia (Table 1). O. denticulata is ant predator of other invertebrates, in Indonesia, these ants found are in shrubs, dryland agriculture, and settlements (Latumahina et al 2015). This species is moderately large with hard-bodied species with large blunt teeth on the sides of the pronotum and a crenulate anterior clypeal margin (General and Alpert 2012).…”

Analisis Perubahan Penutupan Lahan Di Dalam Kawasan Hutan Lindung Gunung Sirimau Kota Ambon

“…Berdasarkan data deforestasi dalam kawasan hutan lindung untuk wilayah Provinsi Maluku tahun 2018-2019 terjadi pada kelas penutupan hutan sekunder sebesar 66,7 hektar (Anonim, 2020). Latumahina (2015) menegaskan hasil penelitiannya bahwa kondisi Hutan Lindung Gunung Sirimau berada dalam kondisi yang semakin memprihatinkan setiap tahunnya. Keadaan ini mengarah pada gejala degradasi hutan yang diakibatkan oleh faktor manusia (antropogenik) dan faktor alam (non antropogenik) yakni penebangan liar, pembakaran hutan, pembanginan sarana permukiman, erosi, banjir dan serangan hama penyakit.…”

Keanekaragaman dan Kepadatan Semut (Hymenoptera, Formicidae) di Lahan Gambut Alami

“…Menurut Latumahina (2016), gangguan pada vegetasi menyebabkan terganggunya komunitas semut, karena terganggunya habitat dan bahan makanan yang diperlukan bagi hidupnya. Gangguan tersebut berasal beberapa faktor antara lain, pembakaran lahan dan pembakaran hutan menyebabkan suhu di permukaan tanah menjadi tinggi dan tanah cendrung menjadi kering (Tabel 2).…”
