Abstract

Mayacaceae Kunth is a monogeneric family with a single genus, Mayaca Aubl. Its family members are herbs found in swamps, lakes, and rivers. The family is distributed throughout the Neotropics, except for M. baumii Gürke, which is only found in Africa [de Carvalho MLS & Machado AFP., Revisiting Mayacaceae Kunth towards to future perspectives in the family, Rodriguésia 66(2): 421-427. 2015]. Mayacaceae consists of ten species and one of them, Mayaca fluviatilis Aubl. is widely cultivated as an aquascape ornamental plant, including in Indonesia. This aquatic family is not yet recorded in the Flora of Java Vol. III [Backer CA & Bakhuizen van den Brink RC., Flora of Java, Vol. III, Groningen: NVP Noordhoff. 1968].

Abstract

Corridor area of Gunung Halimun Salak National Park was degraded and fragmented by human activities. However, little is known about recovery process in tropical degraded forest under different land use history. To clarifyvegetation structure and forest recovery related to land use history we placed 22 plots (11 of 10 x 10 m2 in abandoned plantation and 11 of 20 x 20 m2 in secondary forest, respectively). DCA (Detrended correspondence analysis) discriminated the plots into three community groups. Swieteniamacrophylla –Agathisdammaa community in abandoned plantation where had a land use history of clear felling.Maesopsiseminii–Cyathea spp. community had a history of severe human disturbance. Fagaceae-Schimawallichii was in less disturbed forest. Below the plantation canopy, light tolerant species, weeds, grasses, and fern of Dicranopteris linearis were dominant. Some exotic plants spread to the disturbed forest. The less disturbed forest in distant area from village remained in good condition as indicated by dominancy of old forest species. For the forest rehabilitation in severely degraded area, human intervention by planting native species can be suggested to avoid invasive species occupancy as well as accelerate forest recovery.

Abstract

Curug Tilu Leuwi Opat dan Ciwangun Indah Camp adalah kawasan wisata di Kabupaten Bandung Barat yang memiliki frekuensi kunjungan wisatawan cukup tinggi, namun tidak diimbangi dengan penelitian komposisi keanekaragaman hayati yang dapat menjadi panduan dalam penjagaan kedua kawasan wisata tersebut. Penelitian ini bertujuan mengkaji komposisi keanekargaman burung dan distribusi spasial secara sederhana di Curug Tilu Leuwi Opat (CTLO) dan Ciwangun Indah Camp (CIC). Burung dapat menjadi indikator kualitas sebuah kawasan karena sensitifitas terhadap perubahan lingkungan yang tinggi Pengamatan dilakukan menggunakan metode Point count dan cruising method berdasarkan panjang jalur (tracking) yang berbeda, di CTLO dipilih 3 point count dan CIC 5 titik point count. Kehadiran burung secara spasial dilihat berdasarkan sudut pengamatan menggunakan kompas dan jarak teramati dari titik point count dan identifikasi tambahan melalui identifikasi suara burung mengikuti website Xeno-Canto. Hasil penelitian menunjukan komposisi burung di CTLO (H’ = 2.50) lebih beragam dari CIC (H’ = 1.74) namun memiliki indeks kesamaan komposisi jenis yang tinggi (51 %). Distribusi spasial menunjukan area penyebaran favorit dari burung adalah kawasan terrestrial dan tidak dekat dengan aliran sungai (curug). dapat disimpulkan bahwa kehadiran burung lebih banyak dijumpai jauh dari curug dan aliran Sungai. Kata kunci: Distribusi, identifikasi suara, indeks kesamaan, indeks shanon, point count.

Abstract

Anthropogenic activities increasingly threaten freshwater availability. The Curug Tilu Leuwi Opat waterfall in the Cimahi River, an important water source for surrounding communities and a popular tourist site, requires an ecological assessment to support effective water management. This study aims to provide an initial overview of the ecological status of waters through an integrative approach that combines benthic macroinvertebrates and physicochemical parameters. Sampling was conducted in two waterfall streams, Kacapi and Aseupan, which are part of the Curug Tilu Leuwi Opat waterfall system. Physicochemical parameters measured included temperature, flow velocity, pH, dissolved oxygen, conductivity, and total dissolved solids. Benthic macroinvertebrates were collected using a Surber net and identified to the lowest feasible taxonomic level, typically morphospecies with some taxa at the family level, and subsequently analyzed using the Shannon–Wiener index, Simpson’s dominance, the Family Biotic Index (FBI), and Canonical Correspondence Analysis. Results indicated excellent water quality (FBI at Kacapi = 4.17; Aseupan = 4.24), driven by the presence of pollution-sensitive taxa from Leptophlebiidae, Tipulidae, and Perlidae, while the slightly higher FBI at Aseupan reflected several moderately tolerant families such as Physidae and Simuliidae. Benthic macroinvertebrate diversity was moderate with no dominant species, indicating stable community structure. Most measured parameters that met established standards met Class I criteria, while dissolved oxygen, conductivity, and flow velocity emerged as the dominant variables shaping community structure. Overall, the aquatic ecological status was excellent, highlighting the role of aquatic biodiversity as a scientific basis for sustainable environmental management
