The majority of mycoheterotrophic herbs live in shady and humid forest. Therefore, the types of mycoheterotrophic plant are very abundant in tropical areas. One of the areas in Indonesia with the tropics is North Sumatera province. Unfortunately, the information about the species of mycoheterotrophic in North Sumatra is still limited. The objective of the research was to figure out the types of mycoheterotrophic plants in North Sumatra. The study was conducted in August until October 2019 in several areas of the Natural Resources Conservation Hall (BBKSDA) of North Sumatra province, the nature Reserve and nature Park. The research sites covered Tinggi Raja Nature Reserve, Dolok Sibual-Buali Nature Reserve, Sibolangit Tourist Park and Sicike-Cike Natural Park. In conducting sampling, the method used was through exploration or cruising method. The list of mycoheterotrophic plant species presented in this study consisted of their scientific names, synonyms, descriptions, distributions, and ecological information. A total of 9 species of mycoheterotrophic plants (4 families) in Sumatra have been found. As for the family Burmanniaceae, there are three species Burmannia championii, Burmannia lutescens, Gymnosiphon aphyllus. On the other hand, as for the Orchidaceae, there are 4 species, such as Didymoplexis pallens, Eulophia zollingeri, Galeola lindleyana, Gastrodia verrucosa while for the Poligalaceae and Tiuridaceae family, simply one type is found: Epirixanthes elongata and Sciaphila Secundiflora, respectively.

The article presents the results of field research conducted in 2020 on the territory of the Ile-Alatau State National Natural Park. As a result of the conducted research, 32 species belonging to 2 families of hemiptera of the infraorder Pentatomomorpha I were identified. Among them, the predominant species composition of the family Lygaeidae is 21 species (66%), and 11 species are known from the family Aradidae (34%). On trophic specialization, they are divided into mycetophagy (11 species), phytophages (21 species, of which politicology – 16 types, wide oligotherapy – 3, narrow oligotherapy – 2). According to the type of food, both taking into account the number and number of species in the complex of hemiptera, phytophages clearly predominate. According to the number of generations per year, the hemiptera of the Ile-Alatau SNNP are divided into 4 groups: acyclic (different stages of development can be found simultaneously throughout the year) – 11 species, monovoltine (one generation per year) - 15 species, bivoltine (two generations per year) – 5 species, polyvoltine (several generations per year) - 1 species. There are 30 species with mesophilic ecology in the study area, only 1 species is hygromesophilus. Among the hemiptera of the Ile-Alatau GNPP, 19 species (61%) overwinter in the imago stage, 11 species (35%) in the imago and larvae stage, and 1 species (4%) in the egg stage.

Abstract The Sibolangit Nature Park area is one of the Nature Parks in North Sumatra which has various types of diverse plants ranging from understorey, epiphytes and various endemic tree species. The purpose of this study was to see the diversity of understorey species found in the Sibolangit Nature Park and its benefits. The results showed that there were 27 types of understorey plants from 18 families. Based on the family, the most commonly found were the Araceae family, namely 6 species (22.22%) and Zingiberaceae (11.11%). The understorey has the potential for medicinal plants, ornamental plants, poisonous plants, etc. The results showed that there were 15 species (55.5%) which were included in the category of ornamental plants, 7 species (25.92%) were included in medicinal plants, 1 species of poisonous plants (3.70%), 1 species of spice plants (3,70%), and 1 species (3.70%) protected plants and 2 species (7.40%) could not be explained scientifically. A protected and endangered plant species is Amorphophallus titanum

AbstractExtratropical angiosperm diversity is thought to have arisen from lineages that originated in the more diverse tropics, but studies of dispersal between tropical and extratropical environments and their consequences for diversification are rare. In order to understand the evolutionary effects of shifts between the tropics and extratropics, defined here as areas that do versus do not regularly experience freezing temperatures, we studied the biogeographic history and associated diversification patterns of Cunoniaceae. We mapped the distribution of all species in the family and combined this with a newly constructed phylogeny for the family. The family shows a long evolutionary association with both tropical and extratropical environments, the tropics house considerably greater species richness of Cunoniaceae. Indeed, both tropical and extratropical environments appear to have had a similar number of lineages until 12 Ma, after which time the number of lineages in tropical areas increased at a faster rate. In addition, community phylogenetic approaches show that tropical regions have markedly less phylogenetic diversity than expected given their species richness, which is further suggestive of recent species radiations in tropical areas. The Cunoniaceae show an atypical pattern for angiosperms of frequent shifts between tropical and extratropical environments, but despite this, shows a more conventional pattern of higher, although recent, diversification rates in the tropics. Our results support the idea that high angiosperm species richness in the tropics may result from the tropics acting as a cradle of recent angiosperm diversification.

Steppe areas of the National Natural Park "Kremenets Mountains" occupy the minimum area in open hills and rocky niches, so the priority tasks are the protection of unique steppe ecosystems.Reproduction of steppe areas is one of the tasks aimed at preserving the diversity of steppe and petrophytic flora, the structure of cenoses in the steppe regions, as well as the habitats of rare steppe plants.The work is based on field research materials conducted during 2012-2018 on the territory of the National Natural Park "Kremenets Mountains". In the course of research, literary data and geo-botanical studies of the Strahov, Vovcha, Sokolina, Maiden cliffs and Zamkov mountains have been processed, flora and phytocenotic features of steppe and meadow-steppe phyto groups, the state and structure of rare species populations have been described.Characterized by the laws of distribution of steppe and meadow-steppe species of plants on the territory of the National Nature Park "Kremenets Mountains". The influence of natural conditions is described, factors which contribute to the decrease in the number of populations of these species are determined. The measures on preservation and reproduction of steppe ecosystems, preservation of the diversity of steppe and petrophytic flora, and the structure of the cenosis of the steppe regions are presented. The age structure of Adonis vernalis L., which grows on the Malyatyn and Vovchyna rivers, is studied.In order to preserve the populations of the listed rare steppe plant species, active measures have been taken within the framework of the National Natural Park "Kremenets Mountains", which consists in reducing the anthropogenic impact and restoring the settlement of rare species. According to the Territory Management Project, the state of afforestation of steppe areas is monitored, shrubs, undergrowth of trees and invasive herbaceous plants (in particular, Solidago canadensis L.) are cleared with which the steppe areas spontaneously grow; some measures are taken to increase the number of rare plants (repatriation).This will promote the expansion of steppe areas, the increase of the proportion of steppe and meadow species in the grassland and increase the area under the populations of individual rare species.

ABSTRACT The nutrient circuit in aquatic ecosystems may seem simple, but the truth is that nutrient biochemical circuits are rather complex. Circuits are established by a series of interconnected biological, chemical and physical processes. Human activities lead to degradation of wet fields. Water quality and quantity have been changed, especially the quantity of polluting substances. Bacteriological studies in lotic ecosystems from Cefa Nature Park were carried out to establish four ecophysiologic microorganism groups: nitrogen-fixing bacteria, amonifying bacteria, nitrifying bacteria and denitrifying bacteria. Recorded values differ greatly from one species to the other according to sample points and season. Higher values in autumn are due to an increased intake of organic matter at the end of the vegetation period. Decomposition processes are intensified because of a growing number of microorganisms. Fishery management influences qualitative and quantitative variations in the microorganism communities of the lotic ecosystems in Cefa Natural Park.
