Anggrek Dataran Tinggi Habema di Distrik Nanggo Trikora, Jayawijaya, Papua

Abstract

New Guinea island is known as a home of tremendous collection of orchids. It is certainly in excess of 2500 species, which is 10-13% of the world’s orchids. Some of those species are well described, but some remained unclear. Therefore many more await to be discovered. The aim of this research is to invent orchid’s species in Habema areas, Wamena. Explorative methods were used in this study. The results showed that there were 19 species consist of Dendrobium 11 species, Agrostophyllum 2 species, Glomera 2 species, Liparis 1 species and Bulbophyllum 1 species. Two species remained unidentified. Among them only five species are terrestrial, and eleven are epiphytes. The altitude is 2900-3700 m above sea levels; the rain fall is 1900 mm/year, humidity 86-95 %, with temperature of 14,5–24 oC.Key words: Orchids, exploration, highland, Habema

Rapid assessment of lichen diversity in Baliem Valley, Jayawijaya, Papua, Indonesia

“…The temperature also varied between 18-26°C. Altitude has strong relationship with air temperature, which affects the physiological activity of organisms (Grytnes et al 2006;Agustini et al 2015;Parizadeh and Garampalli 2017), including lichens (Rafat 2014;Firdous et al 2017). For lichens, altitude is very influential on species diversity (Baniya et al 2010), even to the content of secondary metabolites (Temina et al 2010).…”

“…Tropical rain forests have ecosystems with complex dynamics that contain a variety of habitats for the life of various species. As a country located in tropical region, Indonesia is rich in biological resources, including in Papua (Agustini et al 2015;Kadir et al 2020). Papua has a high diversity of ecosystems, ranging from beaches, lowlands, highlands, to mountains and even snow despite it is located in the equator (Kartikasari et al 2013;Agustini et al 2015).…”

Papua's highland forest ecosystem has a unique vegetation structure.…”

“…Despite the importance of Papuan forests in harboring biological diversity, some forest areas in Papua have experienced deforestation and forest degradation due to regional development of regional land conversion for other land uses, such as housing, plantations, and agriculture. These changes can affect forest ecosystems and flora that grow in them (Agustini et al 2015), including lichen (Sujetovienė 2017).…”
