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.
The methodology and applicability of the study of spatial distribution of trees in Serbian forestry have been insufficiently reported and presented. This paper, based on mathematical?statistical principles, analyses the method of spatial distribution of spruce trees in the Nature Reserve 'Jankove Bare' in the National Park 'Kopaonik'. The following methods in the group of distance methods were applied: Kotar's method (1993), T2?method, and the index of distance dispersion (Johnson, Zimmer, 1985). The study results in a pure uneven-aged spruce stand based on all three methods showed that spruce trees are randomly distributed over the stand area. Therefore, environmental conditions in the study stand can be regarded as homogeneous and equally suitable for tree growth, and there are no significant interactions between the trees, which could cause a higher competition between the trees for nutrients, water, etc.
Based on genetic, morphological and chromatical comparisons we evaluate the taxonomic status of two southern Vietnamese forest-dwelling populations of the Cyrtodactylus irregularis species complex. We confirm the allocation of the population from Binh Chau—Phuoc Buu Nature Reserve (Ba Ria—Vung Tau Province) to C. cattienensis and we describe the population of Nui Chua National Park (Ninh Thuan Province) as Cyrtodactylus sangi sp. nov. This brings to 18 the number of species within the C. irregularis complex and to 41 the number of described Cyrtodactylus species recorded from Vietnam.
Acrobeles fananae spec. nov. is described from two localities on the west coast of South Africa. The new species is characterised by body length of 0.7-0.8 mm; relatively slender, cylindroid body, abruptly ventrally bent in vulval region; vulva with protruding lips and situated in a sunken area; three incisures in lateral field; and cuticle with an intricate interlocked block-like pattern. Additional data is presented on the morphology of Seleborca complexa (Thorne, 1925) collected in the same area.
Densities and population estimates are presented for the little known Yellow-breasted Racquet-tail Parrot Prioniturus flavicans, a species endemic to the Indonesian island of Sulawesi. Sixteen months of fieldwork was conducted within two protected areas in the island's northern peninsula. Densities were found to be much greater in the Bogani Nani Wartabone National Park than in the Tangkoko Duasaudara Nature Reserve: 16.27 and 7.18 birds/km2, respectively. The species has a much more restricted range than previously thought, being confined to the eastern two-thirds of the north peninsula. The remaining suitable habitat within this range, lowland rainforest, is estimated to be c. 11,300 km2. Using this figure in conjunction with density values we estimate that the world population for this species may be greater than 44,650 birds. Whilst such a population size is higher than previously thought, the very restricted distribution of the species causes concern for its future as loss and fragmentation of forest habitat are ongoing within its range.
The Zádielska dolina (“Zadiel Gorge“) belongs to the most beautiful and from a natural science perspective to the most interesting landscape formations of the Slovak Karst. The area represents the National Nature Reserve in the National Park and is part the European Network of Protected Areas NATURA 2000. The site is characterized by climbing activity. This article provides suggestions of attractiveness in the field of climbing that respect the development of tourism in accordance with nature and landscape conservation. The basis for the proposals were theoretical knowledge, thorough analysis of the area and own experience with the issue. Recommendations from other climbing places and identification of problems between climbing and nature, have been key for us in making appropriate proposals. The increasing interest in adventure tourism, including climbing, means a global trend in tourism and therefore it is necessary to pay close attention to this issue.
A well established population of the soil-dwelling polychaete Parergodrilus heideri Reisinger, 1925 was discovered during a survey of the woodland soil fauna in the Astroni Crater (a State Nature Reserve near Naples, Italy, 50 m a.s.l., 40°50′52″N, 14°08′59″E) (Fig. 1A, B). This is the southernmost capture of this worm in Europe (Fig. 2A), although a lower latitude record (35°22′0.4″N, 127°34′52″E), the sole (so far) outside the continent, has been reported recently from Korea in this same journal (Dózsa-Farkas & Hong 2010). In Italy the species was known only from the Casentino National Park (1,120 m a.s.l.) in Tuscany and the Regional Park of Suviana and Brasimone Lakes (975 m a.s.l.) in Emilia Romagna (Rota 1997; Rota et al. 2001). Also in central Europe the species appears confined to mountain habitats (650-1,200 m a.s.l.), the lowland records being located along the northern coasts of Spain and Germany and in southern Sweden (Fig. 2A, B).
Environmental protection regulations influence the use of real property. Land located within the borders of a national park or nature reserve is subject to partial or total restriction on development by construction, as well as, amongst others, business, trade, manufacturing or agricultural activities. Such areas are also subject to landscape protection, whereby real development by construction is possible, but only under the condition that it does not clash with the landscape values of the area. Therefore, real property management in such areas requires careful coordination with the relevant legislation concerning environmental protection.
While it is currently possible to obtain such information from existing environmental protection databases and systems, this has practical problems owing to the large amount of them and their scattered locations. Additionally, as each institution involved in environmental issues has collected material independently, there is a high level of data repetition as well as incomplete data. Such problems make it difficult to make full use of the database systems.
A lack of communication and reference between these databases and systems can create confusion. Comparative data on the same subject often differs depending on the source (as concerns graphic presentation and, much less frequently, data attributes). For example, the course of the same river differs depending on which data resources are used (NAŁĘCZ 2007). There are several hundreds of databases and registers maintained in Poland, with almost 300 databases and registers controlled by the Ministry of Environment. Almost 60 such databases can be found in public administrative bodies alone. A portion of the data regarding this topic is openly available on the Internet.
The aim of the paper is to present the existing information systems concerning environmental protection. The paper will also examine data obtained from these resources, as well as their availability and connections with real property management activities.
Indonesia, like many other developing countries, is turning to ecotourism in an attempt to integrate the goals of development and nature conservation. Although ecotourism may be a valuable tool for preservation of biodiversity, it can have long-term negative effects on reserves, wildlife and local communities if improperly managed. In this study the authors evaluated ecotourism in the Tangkoko DuaSudara Nature Reserve, North Sulawesi, by examining trends in visitor numbers, the tourist experience, the distribution of tourist revenues, and tourist impact on the Sulawesi black macaque Macaca nigra and spectral tarsier Tarsier spectrum. The data collected showed that, although tourism is expanding rapidly, local benefits are not being fully realized, the reserve does not generate enough money to implement management, and primate behaviour is being affected. There is urgent need for a change in legal status of the reserve if ecotourism is to be managed. National park status would accommodate ecotourism planning and development, provide for greater participation by the local community, and allow for increased revenues for management.
