“…The gap opening in the forest is correlated with abiotic factors such light availability, soil and air temperature, air vapor pressure deficit, soil nutrient and water content [10]. There is evidence that variation of colour and size of the pitcher could be affected by light availability [3,11]. The Nepenthes variation, even though with a single species, could be explained by geometric morphometric (GM) method [12,13].…”

Light exposure from the sun is the most crucial variable for producing optimal pitcher size and colour variation in Nepenthes. This study aimed to observe the effect of forest canopy structure on morphological character of Nepenthes ampullaria’s pitcher parts (longitudinal, front, and peristome) both on size and shape using Geometric morphometric (GM) approach and its prey diversity. We classified the forest canopy structure into two categories: inside the canopy and open space area (gap). We used Unmanned Aerial Vehicle (UAV) images to build Canopy Height Model (CHM). Then, ForestGapR R package used to analyse and generated the forest gaps area. The prey specimens and photograph samples comprised from 9 individuals with three lower pitchers in open space area with high light exposure as well as shaded area inside the canopy. Total of 54 images were marked by point and curve to generated a landmark analysis using GeoMorph R package. Based on GM analysis, we observed that the forest canopy structure could affect Nepenthes pitcher shape but not in pitcher size. Our field result revealed Nepenthes ampullaria likely dominated by darker colour with a red spot in the shaded area and bright green colour in the open. However, based on our study the pitcher in shaded area inside the canopy have a larger number of prey species than the open area.

“…In Bangka Belitung Province, N. mirabiilis was also found in swamp forest (Rizqiani et al 2018), and in peat swamp of Borneo, N.mirabilis was also the dominant climber (Hidayat et al 2018). In Halmahera Island, N. mirabilis was found in lowland forest and edge of swamp (Cahyono et al 2019).…”

Abstract. Wiryono Mersyah R, Tarantona M. 2020. Flora of Danau Dusun Besar conservation forest in Bengkulu Province, Indonesia. Biodiversitas 21: 5640-5649. Few studies on flora of freshwater swamp forest in Sumatra have been published and accessible online. This study aimed to assess the composition and diversity of plant species and to describe the dominant species in conservation forest of Danau Dusun Besar Nature Reserve and Nature Tourism Park in Bengkulu which consists mostly of freshwater swamp forests and a lake. Data collection was done using a combination of quantitative methods with systematic plots and qualitative methods through observation. The quantitative data were analyzed to determine indexes of diversity, evenness and importance value. This study recorded 23 species of trees with diversity index (H′) and evenness index (E) of 0.29 and 0.09, respectively, and recorded 136 species of shrubs and herbs with H′ and E values of 3.68 and 0.75, respectively. The most dominant species of trees was Alstonia spatulata, of shrubs and herbs Stenochlaena palustris. The small diameter class of trees and the covering of trees with climbers indicated that the large trees had been cut. We recommend further studies with more and better-located plots to get better data on the vegetation composition and structure, including the invasion of alien species Ludwigia peruviana and the effect of climbers on trees.

“…Morphological markers of Nepenthes had been widely used in genetic diversity studies, including N. gymnamphora and N. mirabilis (Iqbal and Susandarini, 2015), N. ampullaria, N. gracilis, N. rafflesiana and N. mirabilis (Selviana et al, 2018), N. ampullaria, N. tobaica, and N. mirabilis (Mukra et al, 2018, N. gymnamphora (Putra and Fitriani, 2018), N. grancilis Korth., N. maxima, N. refflesiana Jack., and N. mirabilis (Cahyono et al, 2019). The use of morphological markers to evaluate the genetic diversity of Nepenthes in Indonesia was still limited in some populations such as N. gracilis Korth, N. rafflesiana Jack, N. mirabilis, N. khasiana, and N. ampullaria.…”

Nepenthes, also known as pitcher plant, are unique and interesting flora developed as ornamental plants. This species has an attraction not only on the flowers but also on the diverse shapes and colors of the pitchers. Each Nepenthes species and hybrid has a variety of characters. The genetic relationship and diversity in Nepenthes species and hybrids can be determined based on the morphological characterization. The purpose of this study was to determine the similarity level among the Nepenthes accessions based on 31 qualitative characters. In this study, 30 Nepenthes species and 11 hybrids were used. The range of the similarity coefficient of Nepenthes species was 0.28-0.65, and divided into two major groups namely group A and B. Group A was the Nepenthes population which had petioles consisted of 17 accessions, while group B had folius consisting of 24 accessions. It indicated that when the similarity value is higher, the similarity level between each plant becomes higher. Principle Coordinates Analysis (PCoA) provided an overview of the relationship among the genotypes in coordinates. Species with a high similarity coefficient were in a close position, whereas species with a low similarity coefficient were in a remote position. Based on the PCoA, the species were grouped based on the similar characters, which was supported by the dendrograms.
