Abstract

The prevalence of V.ovalifolium in Pulau Dua Nature Reserve was surveyed. This parasite was observed parasitizing on only two host species, Excoecaria agallocha and Thespesia populnea, among 11 potential host tree species in the study area. This phenomenon, contemporarily coined as local host specificity, is complementary to a small endnote on Backer & Bakhuizen van den Brink’s 1965 Flora of Java vol. II. V.ovalifolium’s prevalence is higher as the increase on host tree DBH, as the decrease of infested host branch diameter and as the increase of host tree branching order. Two later findings point at Dicaeum trochileum as V.ovalifolium seed disperser among 90 bird species living on the nature reserve.

Abstract

Human-wildlife conflict is a major threat to many declining wildlife species worldwide. The roosting population of the endangered Christmas Island Frigatebird at Pulau Rambut, Teluk Jakarta, is prone to entanglement in fishing lines and nets used by local fishermen for catching fish. We conducted interviews with local fishermen during May-July 2018 in order to quantify their perception of the frigatebird. Subsequently we conducted an educational program about frigatebirds by means of penyuluhan, an Indonesian style, culturally-sensitive, informal discussion technique. There was significantly greater positive perception of Frigatebirds in the group attending a series of informative penyuluhan meetings compared to the control group. As Indonesia has a strong oral tradition, we believe that this method offers potential benefits as a tool to improve conservation outcomes for threatened species.

Abstract

Abstrak Talun atau hutan kebun memiliki potensi sebagai habitat kukang jawa (Nycticebus javanicus) di luar kawasan yang dilindungi. Salah satu karakter habitat adalah keberadaan pakan dalam habitat. Penelitian ini dilakukan pada bulan Juli hingga September 2016, bertempat di kawasan talun Desa Cipaganti, Garut, Jawa Barat. Metode yang digunakan adalah metode deskriptif. Sampel penelitian adalah kukang dewasa yang sudah dipasang radio-collar. Pengambilan data pakan berupa jenis pohon dan jenis pakan yang digunakan.Data pakan dikumpulkan selama pengamatan perilaku. Metode yang digunakan dalam pengamatan perilaku adalah instantaneous point sampling dengan interval waktu lima menit. Pengambilan data vegetasi habitat  dilakukan dengan mengamati struktur dan komposisi vegetasi. Jenis pakan yang dimakan oleh kukang jawa jantan dan betina dianalisis dengan menggunakan Chi-square. Terdapat tiga jenis pakan utama dari kukang jawa, yaitu getah (71,27%), nektar (16,09%), serangga (11,49%), dan bunga (1,15%). Terdapat tiga suku tumbuhan yang digunakan oleh kukang jawa sebagai sumber pakan, yaitu  Fabaceae, Arecaceae, dan Moraceae.  Abstract Talun or forest-garden has a potential role as habitat for javan slow loris (Nycticebus javanicus) outside its protected area. One of the habitat characteristics is the presence of feeds in the habitat. The study was conducted from July to September 2016, in a talun area of Cipaganti Village, Garut, West Java. The method used in this study was descriptive. The samples of the study were adult individuals that had been installed with a radio-collar. Data on tree species as feeds were collected during observations on behavior. The method used in the behavior observation was instantaneous point sampling with five-minute intervals. Data retrieval of the vegetation was conducted by observing the structure and composition of the vegetation. Types of the feed consumed by the male and female animals were analyzed by using Chi-square test. There were three types of main feeds for javan slow loris, those were gum (71.27%), nectar (16.09%), insect (11.49%), and flower (1.15%). There were five families of plant that used by the javan slow loris as the source of feeds.  Permalink/DOI: http://dx.doi.org/10.15408/kauniyah.v11i1. 4914
