Human activities in forest areas such as over-harvesting of Begonia species without being balanced with their cultivation activities can threaten the existence of Begonia in nature. Autecological studies of species in their natural habitat are the initial activities for the conservation of plant species. The purpose of this study was to study the distribution of Begonia on Flores and environmental/ microclimate characteristics in several locations on Flores Island. The 10x10 m plots were placed with purposive sampling with a minimum interval of 50 m. Multivariate analysis using Canonical Corespondence Analysis (CCA) was employed to determine the effect of microclimatic factors on the composition of vegetation. Begonia kelimutensis is endemic in Kelimutu National Park, Flores lives at an altitude of 1,527 asl, at soil pH 5,8 and soil moisture of 75%, with a slope of 10 ° on the forest floor and light intensity 4,640 klux. In addition, five types of Begonia that we estimate have not been identified and two of them are identified as Begonia sumbawaensis Girm. and Begonia brangbosangensis Girm. Begonia kelimutuensis is distributed at a higher altitude than Begonia brangbosangensis. B. sumbawaensis is influenced by the slope factor while B. longifolia tends to be related to the air humidity factor. B. kelimutuensis is also often found living with Macaranga sp., and Litsea sp. B. brangbosangensis, also found near Homalanthus sp. and Calliandra callothyrsus.

Indonesia is a biodiversity country and has much of samples of bioacoustics but there are no bioacoustics data collected and saved to be referred. Bioacoustics is a study of frequency range, sound amplitudo intensity, sound fluctuation, and sound patterns. It is very useful to study more about population presumption and species determination. This insect bioacoustics research is done at Gunung Gede Pangrango National Park and aims to analyse variety of sound frequency of cicada and cricket. Methods which are used are recording the sounds, editing and analyzing the record result with Praat and Raven Lite 2.0 softwares, and analysing the environment. Analysing the sounds which is done is to find miximum frequency, minimum frequency, and average frequency. The result of the sounds analysis is compared to database in Singing Insect of North America (SINA). Environmental analysing includes temperature, air humidity, and light intensity. There are nine cicada sound recording files and twenty four cricket sound recording files. Cicada has high sound characteristic (9,168.2 Hz) and cricket has low sound characteristic (3,311.80 Hz). Comparation to Singing Insect of North America (SINA) database shows that the cicada’s sound is resemble to Tibicen marginalis and the cricket’s sound is resemble to Grylodes sigillatus.

The distribution of a species can help guide the protection activities in their natural habitat. Conversely, the lack of information on this distribution makes the protection strategy of this species difficult. The research was conducted in Way Canguk Research Station, Bukit Barisan Selatan National Park from January until March 2018. The purposes of this research were to create a distribution prediction map of Sunda pangolin (Manis javanica) and estimating the environment variables that most influenced the probability of the distribution. Fourteen points of camera trap coordinates were used for presence data with nine types of environment variables such as elevation, slope, understorey, canopy cover, distance from roads, distance from rivers, distance from villages, food source, and distance from the threat. The result of maxent showed an Area Under the Curve (AUC) value of 0.909 categorized as very good. The highest probability of Sunda pangolin distributions was in the Pemerihan Resort and Way Haru Resort area, while the dominant environmental variables included the distance from the village, the canopy cover, and the distance from threat with the value 47.7; 25.85; and 15.8%, respectively. Prediction maps and environment variables can help to identify the population of Sunda pangolin in the wild and can provide input for the national parks to prioritize protection areas for Sunda pangolin from the increased poaching.

The results of research got 44 types of orchid, the research there were 3 kinds of orchids growth characteristic, epiphytic amount 38, terrestic 5, and litofit 2, while the type its growth dominated by simpodial orchid amount 26 types. Type many found that was Eulophia spectabilis. Based on the height of place, type grow in higher position was Trichotosia sp that is 1252 m dpl while lower position was Bulbophyllum sp.2, Dendrobium stuartii, Oberonia sp.1, Pholidota sp.2, dan Luisia sp.1 that is 764 m dpl. Based on light intensity visually, the most commonly found orchid in the light intensity is half as much as 35.

Average Temperature

Agricultural production is influenced by environmental factors such as temperature, air humidity, soil water, light intensity, and CO2 concentration. However, climate change has influenced the values of average temperature, precipitation, global atmospheric CO2 concentration, or ozone level. Thus, climate change could lead to different situations on plants and consequently influence agricultural production. With this chapter, the authors intend to research how climate change influences some plant metabolisms (such as photosynthesis, photorespiration, transpiration, among others) and therefore agricultural production.

The Relationship

Greenhouse and growth chamber experiments with potted plants were conducted to determine the effects of interspecific root and canopy interference, light intensity, and soil moisture on water uptake and biomass of soybean, common cocklebur, and sicklepod. Canopy interference and canopy plus root interference of soybean with common cocklebur increased soybean water uptake per plant and per unit leaf area. Root interference with soybean decreased common cocklebur water uptake per plant. Canopy interference of soybean with sicklepod increased soybean water uptake per unit leaf area, while root interference decreased uptake per plant. Combined root and canopy interference with soybean decreased water uptake per plant for sicklepod. Soybean leaf area and shoot weight were reduced by root interference with both weeds. Common cocklebur and sicklepod leaf area and shoot weight were reduced by root and canopy interference with soybeans. Only common cocklebur root weight decreased when canopies interfered and roots did not. The relationship between light intensity and water uptake per unit leaf area was linear in both years with water uptake proportional to light intensity. In 1991 water uptake response to tight was greater for common cocklebur than for sicklepod. The relationship between soil moisture level and water uptake was logarithmic. Common cocklebur water uptake was two times that of soybean or sicklepod at −2 kPa of pressure potential. In 1991 common cocklebur water uptake decreased at a greater rate than soybean or sicklepod in response to pressure potential changes from −2 to −100 kPa.
