Calliphoridae and Mesembrinellidae include Diptera species that are good indicators of changes in forest environments. The present work aimed to inventory the Calliphoridae and Mesembrinellidae in Ilha Grande National Park and correlate the abundance of these organisms with environmental variables. Adult dipterans were collected during two expeditions in 2019 using two sampling methods, a Malaise trap and baited traps, distributed on two islands in the park. During the study, 1,007 individuals of 12 species of Calliphoridae and four species of Mesembrinellidae were collected. Family Calliphoridae was more abundant (97.12%). The abundance of native species showed a strong negative correlation with the abundance of the genus Chrysomya. Rodrigues Island (Island I) had higher diversity levels and no species of Chrysomya were recorded in this area, which may indicate a greater degree of environmental preservation. The results indicate that human action in natural environments can negatively impact species diversity, as found in Ilha Grande National Park that, historically, was partially occupied and is still in the process of regeneration.

Aim of this study is to examine and evaluate the ecology - based environmental education program which was applied in years between 2003-2006 Kazdagi National Parks in the Western Turkey. Ecology - based environmental education aims at using natural and cultural resources of Kazda ð ı National Park to teach graduate research assistants and scout teachers about the nature. The expectation is to increase the environmental awareness of participants in general. At the end of the education program, it is expected that the participants will develop a better understanding of local, regional, national as well as international environmental problems; will be able to discuss and provide alternative solution to global ecological crises; and will take action in their individual lives towards creating a more sustainable environment for future. The main or purpose of the project will be to teach natural interactions in an ecosystem. Emphasis will be given to human action that has been interrupted that interaction and made natural environments less sustainable. Therefore, particular emphasis will be given to cultural ecology of the protected area and the participants are expected to develop a thorough understanding of human and environmental interaction.

Abstract Species of Acanthaceae are predominantly associated with conserved forest environments such as Iguaçu National Park (PARNA Iguaçu), which is composed of Semideciduous Seasonal Forest and Araucaria forest. The aim of this work was to perform a floristic study of Acanthaceae of PARNA Iguaçu, with botanical illustrations, an identification key and descriptions of the species. Collections were carried out monthly from August 2015 to July 2016, in the areas of Céu Azul, Capanema and Foz do Iguaçu. The individuals collected were deposited in the UNOP herbarium and the specimens present in the herbaria EVB, HCF, MBM and UNOP, as well as in the virtual herbaria Reflora and SpeciesLink, were analyzed. A total of 13 native species were recorded from Atlantic Forest, distributed in seven genera. Justicia was the most representative, with five species. In all, 12 new records were made for PARNA Iguaçu, of which eight are new records for Semideciduous Seasonal Forest. Of the species found, three are threatened with extinction, one of which is considered vulnerable and two are categorized as endangered, which reinforces the role of PARNA Iguaçu in in-situ conservation in the state of Paraná.

In Virtue Of

Aesthetic and historical values are commonly distinguished from each other. Yet there has not been sustained discussion of what, precisely, differs between them. In fact, recent scholarship has focused on various ways in which the two are related. I argue, though, that historical value can differ in an interesting way from aesthetic value and that this difference may have significant implications for environmental preservation. In valuing something for its historical significance, it need not always be the case that there is a reason to want people to experience the entity. Valuing something for its aesthetic merit, by contrast, does imply a reason to want people to experience the entity. I suggest that in virtue of this difference, some historical values may offer better justification for preserving natural environments than do aesthetic considerations.

Three Rivers

Six major rivers flow through the Kruger National Park (KNP). All these rivers originate outside and to the west of the KNP and are highly utilized. They are crucially important for the conservation of the unique natural environments of the KNP. The human population growth in the Lowveld during the past two decades brought with it the rapid expansion of irrigation farming, exotic afforestation and land grazed by domestic stock, as well as the establishment of large towns, mines, dams and industries. Along with these developments came overgrazing, erosion, over-utilization and pollution of rivers, as well as clearing of indigenous forests from large areas outside the borders of the KNP. Over-utilization of the rivers which ultimately flow through the KNP poses one of the most serious challenges to the KNP's management. This paper gives the background to the development in the catchments and highlights the problems which these have caused for the KNP. Management actions which have been taken as well as their results are discussed and solutions to certain problems proposed. Three rivers, namely the Letaba, Olifants and Sabie are respectively described as examples of an over-utilized river, a polluted river and a river which is still in a fairly good condition.

Pilgerodendron uviferum (D. Don) Florin is an endemic, threatened conifer that grows in South America. In the sub-Antarctic territory, one of the most isolated places in the world, some forest patches remain untouched since the last glaciation. In this study, we analyze the tree structure and tree diversity and characterize the environmental conditions where P. uviferum-dominated stands develop within the Magellanic islands in Kawésqar National Park, Chile. An environmental matrix using the databases WorldClim and SoilGrids and local topography variables was used to identify the main environmental variables that explain the P. uviferum-dominated stands. PCA was used to reduce the environmental variables, and PERMANOVA and nMDS were used to evaluate differences among forest communities. The results show that two forest communities are present within the Magellanic islands. Both forest communities share the fact that they can persist over time due to the high water table that limits the competitive effect from other tree species less tolerant to high soil water table and organic matter. Our results contribute to knowledge of the species’ environmental preference and design conservation programs.

Abstract A taxonomic treatment of the genera Turnera and Piriqueta in the state of Pernambuco, northeastern Brazil, is presented. Fourteen species of Turnera and six species of Piriqueta were found in the Atlantic Forest and Caatinga, of which nine are endemic to Brazil. Turnera pernambucensis is threatened and restricted to the Atlantic Forest of Pernambuco, while T. joelii is a new record for the state. The species predominate in steppe savanna and semideciduous seasonal forest, but several of them grow naturally in anthropized areas. Catimbau National Park is the locality with the highest species richness. Tristyly is recorded for the first time in Piriqueta guianensis. Identification keys, descriptions, illustrations, distribution maps, and comments about habitat, flowering, fruiting, and morphological relationships are provided.

Treinta estaciones en el Parque Nacional El Kala (Noreste de Argelia) fueron objeto de un inventario florístico que se centró en el estudio de la ecología de geófitos bulbosos y tuberosos. La flora se caracteriza por una alta proporción de taxones raros y/o endémicos, entre ellos, 6 especies son endemismos algero-tunecinos pertenecientes a la familia Orchidaceae. En este trabajo, se da a conocer la presencia de una nueva especie para la flora argelina, Ophrys fusca subsp. lupercalis. Los análisis multivariantes revelaron, ciertas variables ambientales que determinan la distribución de los geófitos. Los lugares de interés son particularmente sensibles a las amenazas, particularmente las de origen antrópico. Thirty stations at the El Kala National Park (North Eastern Algeria) were the subject of a floristic focused on the study of the ecology of bulbous and tuberous geophytes. The floristic analysis was used to draw up a checklist of 67 species belonging to 36 genera and 14 families, among of which 19 species a high proportion of rare and/or endemic taxa; among them six signed taxa are endemic to algerian-tunisian mainly represented by family of Orchidaceae. In this work, we recorded the presence of a new species for the Algerian flora which is Ophrys fusca subsp. lupercalis. Multivariate analyses revealed certain environmental variables determining the distribution of geophytes. The visited sites show an alarming vulnerability and subject to threats, particularly anthropogenic ones.
