Prinsip Ekologis Untuk Kehidupan Berkelanjutan Perspektif Teologi Islam: Kajian Atas Kitab Rasail al-Nur Sa`id Nursi

<p><span lang="EN-US">Sa`id Nursi argues that nature and the environment have fixed principles that function to maintain the continuity of life while problems arise when the patterns of human environmental activity tend to contradict these principles so that life is threatened. This paper discusses the principles of ecology according to Sa`id Nursi as the basis for implementing the sustainable living agenda. Primary data of this qualitative study were obtained from Rasail al-Nurwhich was described as well as analyzed using a compare and contrast model with relevant environmental theories. The two findings of this study are that Nursi first built an ecological principle based on the tajalli principle of <em>al-asma al-husna</em>, namely cleansing (<em>at-tandzif</em>) the manifestation of <em>al-Quddus</em>, interdependence (at-<em>tasanud</em>) of <em>al-Fard's</em> manifestation, harmony (<em>at-ta`awun</em>) <em>al-Fard</em>, dynamic balance (<em>at-iqtishad wa al muwawazanah</em>) manifestation of <em>al-hakim</em>. Second, Nursi considers humans to be caliphs because they have the most perfect ecological elements in manifesting the attributes of Allah Almighty. Sa`id Nursi emphasized that the human community must maintain and implement this principle for the sustainability of the nature it occupies. The sustainability of life is directly proportional to the implementation of ecological principles.</span></p>

ELEMENTS OF THE EDUCATIONAL SYSTEM IN THE ECOLOGICAL FIELD PRINCIPLES OF ENVIRONMENTAL LEGISLATION

This article has as a starting point the definition of the concept of ecological principles. Then, after classification of the principles of ecology (domestic principles and international principles), we present and critically analyze and compare the main principles in the field of ecology. Among the ecological principles on the domestic chain, we present and analyze 11 principles, namely: pollution must be combated at the source; the interests of environmental protection must be taken into account in all design or execution decisions; any exploitation or use of natural resources must be avoided if it is accompanied by damage; it is necessary to raise the level of scientific and technological knowledge, inter alia by supporting scientific research; the costs of preventing and combating pollution to be borne by the polluter; the activity of one state not to harm the environment of another state; during the elaboration of the community policy in the field of environmental protection to take into account the interests of the developing states; community environmental protection policy must be developed in the long term and protection must be comprehensive and international, which is achieved, inter alia, through cooperation within international bodies; the cause of environmental protection is everyone's responsibility and for this reason education is irreplaceable; depending on the source of pollution, the most appropriate level of action must be established taking into account the nature of the pollution, the necessary measures, the characteristics of the protected territory. This principle is defined as a "subsidiary principle"; it is necessary to harmonize and coordinate national policy in the field of environmental protection in accordance with the long-term commonly accepted directives. We also present and analyze the principle according to which environmental protection must be an essential element of the economic and social policy of the state. Finally, another ecological principle, the principle of prevention of ecological risks and damage

COMPARISON OF SUBJECTS OF THE URAL FEDERAL DISTRICT BY THE SHARE OF VEGETABLE COVER

The ecological consolidation of vegetation according to three classes of the UN soil cover (grass + shrub + trees) is considered. The ecological coefficient is calculated by dividing the share of vegetation by the share of changed land. For the rating, the forest-agricultural coefficient is convenient as the ratio of forest area to arable land. The ecological principle of the consolidation of 13 types of land is proposed, which makes it possible to carry out the ecological consolidation of the vegetation cover and altered human land. According to these proposed criteria, the ranking of the subjects of the Ural Federal District was carried out.

Sufficient versus optimal climatic stability during the Late Quaternary: using environmental quality to guide phylogeographic inferences in a Neotropical montane system

Quaternary climatic oscillations affected species distributions worldwide, creating cycles of connectivity and isolation that impacted population demography and promoted lineage divergence. These effects have been well studied in temperate regions. Taxa inhabiting mesic montane habitats in tropical ecosystems show high levels of endemism and diversification in the distinct mountain ranges they inhabit; such a pattern has commonly been ascribed to past climatic oscillations, but few phylogeographic studies have tested this hypothesis. Here, we combine ecological niche models of species distributions with molecular data to study phylogeographic patterns in two rodents endemic to the highlands of Costa Rica and western Panama (Reithrodontomys creper and Nephelomys devius). In so doing, we apply a novel approach that incorporates a basic ecological principle: the expected positive relationship between environmental suitability and population abundance. Specifically, we use niche models to predict potential patterns of population connectivity and stability of different suitability levels during climatic extremes of the last glacial–interglacial cycle; we then test these predictions with population genetic analyses of a mitochondrial and a nuclear marker. The detailed predictions arising from the different levels of suitability were moderately to highly congruent with the molecular data depending on the species. Overall, results suggest that in these tropical montane ecosystems, cycles of population connectivity and isolation followed a pattern opposite to that typically described for temperate or lowland tropical ecosystems: namely, higher connectivity during the colder glacials, with isolation in montane refugia during the interglacials, including today. Nevertheless, the individualistic patterns for each species indicate a potentially wide gamut of phylogeographic histories reflecting particularities of their niches. Taken together, this study illustrates how phylogeographic inferences may benefit from niche model outputs that provide more detailed predictions of connectivity and finer characterizations of potential refugia through time.

Typology of native species as the shade tree for merbau (Intsia bijuga) plantations in Papua, Indonesia based on ecological species group

Sirami EV, Marsono Dj, Sadono R, Imron MA. 2019. Typology of native species as the shade tree for merbau (Intsia bijuga) plantations in Papua, Indonesia based on ecological species group. Biodiversitas 20: 43-53. Ecological species group is an ecological principle that can be used as a reference in determining the potential native tree species of Papua as the shade trees for merbau in the mixed forest plantations. This research was conducted to identify the potential native trees as the shade for merbau plantation in Papua. The data collection used systematic line technique with hypothetical plot and sampling tree as the plot center. The Dice Index was used to analyze the level of association between merbau and the neighboring trees as well as to serve as a basis for determining ESG and Important Value Index was used to analyze the level of tree dominance. The main potential shade trees consisting of Pometia coriacea Radlk., Lepiniopsis ternatensi Valeton, Spathiostemon javensis Blume, Palaquium amboinense Burck., and Pimelodendron amboinicum Hassk. Whereas complementary and alternative potential shade consisting of Haplolobus lanceolatus H.J.Lam ex Leenh, Haplolobus celebicus H.J.Lam, Horsfieldia laevigata Warb., Horsfieldia irya (Gaertn.)Warb. Prunus costata Kalkman, Sterculia macrophylla Vent., Dysoxylum mollissimum Blume, Pertusadina multifolia (Havil.) Ridsdale, Streblus elongatus (Miq.) Corner and Geijera salicifolia Schott. The main shade trees possessed a main function for rendering shade toward younger merbau in the plantation area. Meanwhile, complementary and alternative shade trees were intended for increasing soil nutrient availability and optimizing microclimate surround merbau seedlings.
