Schinias is a small coastal biotope under environmental pressure. Partial drainage of the wetland and different disturbing activities have degraded ecological habitats and decreased biodiversity for many decades. Recently, the construction of a rowing centre has restored hydrological regime and the area has been designated as a National Park; however, application of conservation measures meets difficulties of social and financial nature. In this paper, bird diversity is used as an indicator to examine Schinias’ ecosystem state, according to three different scenarios: the first one refers to the diversity that had been recorded before restoration of the hydrological regime; the second one refers to the diversity that has been recently recorded and corresponds to the actual condition of the National Park with the rowing center; the third one corresponds to a potential diversity that would be observed in case Schinias became a solar saltwork.

This study aims to determine the socio-economic characteristics of farmers, analyze the income structure, the factors that affect the income of farmers, and the level of household welfare of farmers who live around Bukit Barisan Selatan National Park, Pesisir Barat District. This research is a survey research involving 99 respondents who were randomly selected. Respondents were spread across four subdistricts, namely Bengkunat Belimbing, Ngambur, Pesisir Selatan, and Karya Penggawa Districts. The study was conducted from July to August 2018. The first objective was analyzed qualitatively, the second objective was analyzed using household income analysis, the third objective used multiple linear regression analysis, and the fourth objective was using Sajogyo's criteria (1997). The study suggested that the socio-economic characteristics of the farmers around TNBBS were spread from 15 to 64 years of age with an average age of 43.74 years. The average education level was elementary school, the number of majority of family sizes was from 4 to 6 people (67.68%), and the average land was 1.41 ha. The average household income of farmers is IDR 36,946,883.94 per year, which consists of on-farm income 63.68%, off-farm income 11.00%, and non-farm income 25.33%.. Factors that affect farmers' income are fertilizer costs and labor costs. The welfare of farmers around TNBBS is in quite prosperous category.Key words: characteristics, household income, welfare

The hydrology of the Snake River in Grand Teton National Park is partly determined by releases from Jackson Lake Dam. The dam was first built in 1908 and became part of the National Park system GTNP was expanded to include most of Jackson Hole. Completion of the present structure of Jackson Lake Dam occurred in 191 7 and resulted in an increase above the natural level of Jackson Lake of 11.9 m. The Bureau of Reclamation (BOR) manages the dam and sets discharge schedules, primarily to meet agricultural needs, and to a lesser extent the needs of recreational river use. Major changes to the hydrological regime of the Snake River include lower than natural peak releases, decrease in frequency of extreme flood events, and unusually high flows from July to September. In addition, peak releases prior to 1957 were not synchronized with spring runoff but shifted to July or early August. Changes in inundation frequencies of floodplains, inundation duration and timing of peak flows have profound effects on the extent and composition of the riparian zone.

AbstractThe new species Coniarthonia aurata E. L. Lima, M. Cáceres & Aptroot, Cresponea endosulphurea A. A. Menezes, M. Cáceres & Aptroot, Cryptothecia macrocephala E. L. Lima, M. Cáceres & Aptroot, and Synarthonia sarcographoides Aptroot, A. A. Menezes, E. L. Lima & M. Cáceres are described from Caatinga vegetation in NE Brazil. They were found in the Chapada do Araripe in the state of Ceará and/or the Vale do Catimbau National Park in Pernambuco. Coniarthonia aurata has weakly organized, semiglobose apothecia with golden crystals, and on first impression looks like the anamorph of a Tylophoron. Cresponea endosulphurea has a pigment of the group of xantholepinones in the thallus. It is the first time that a substance from this group is reported from the Arthoniales. Cryptothecia macrocephala has strongly macrocephalic ascospores and contains psoromic acid in the thallus. Synarthonia sarcographoides is only the third species in this rarely found genus. It is characterized within the genus by muriform, brown ascospores, but it is assigned with hesitation to the genus. It is locally quite common.

We describe three new gecko species of the Paroedura oviceps clade, diagnosed by deep divergences in mitochondrial DNA, absence of haplotype sharing in two nuclear genes (sacs and kiaa1239), and morphological differences. Paroedura spelaea sp. nov. is an extremely slender species from karst habitats in the limestone massif of the Tsingy de Bemaraha National Park in western Madagascar, morphologically reminiscent of P. homalorhina but distinguished by the absence of distinct dorsal rows of spiny tubercles. Paroedura fasciata sp. nov. from the small karstic island Nosy Hara in northern Madagascar is phylogenetically placed sister to P. spelaea despite radical morphological differences. It is morphologically most similar to P. hordiesi from the geographically close Montagne des Français massif, but is smaller, has slightly more spiny dorsal scales, and a distinctive colour pattern with light grey dorsal crossbands. The third species, Paroedura kloki sp. nov., is known from Ankarafantsika National Park and the western slopes of Makira, two sites of dry to transitional forest in western Madagascar. It is at least partly arboreal and morphologically very similar to P. oviceps, from which it differs by spiny scales extending over its entire tail. Although incomplete, the available phylogenetic evidence suggests that the karst specialists in the P. oviceps clade (P. fasciata, P. homalorhina, P. hordiesi, P. spelaea) form a monophyletic group which might have diversified by vicariance after becoming isolated, respectively, in their limestone habitats in Tsingy de Bemaraha, Ankarana, Nosy Hara and Montagne des Français.

We describe a third cryptic species of the genus Cyrtodactylus from Phong Nha – Ke Bang National Park, Quang Binh Province, Vietnam. Cyrtodactylus roesleri sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by a combination of the following characters: size small, with a maximum SVL of 75.3 mm; dorsal pattern consisting of dark nuchal band and 4–5 sometimes irregularly shaped dark transversal bands between limbs; ventrals in 34–40 longitudinal rows at midbody; continuous series of 20–28 precloacal and femoral pores in males; subcaudal scales transversally enlarged. It is the 15 th new reptilian taxon described as new from the karst forests of Phong Nha – Ke Bang National Park in the past decade. In addition, it is the 19 th species of Cyrtodactylus known from Vietnam and the third Cyrtodactylus occurring in sympatry in the karst forests of Phong Nha – Ke Bang National Park.

SummaryThe Volcanoes National Park (VNP) in Rwanda, part of the Virunga massif in the Albertine Rift region, boasts some of Rwanda’s best remaining natural vegetation and is home to many endangered and endemic species. The park has suffered from high levels of degradation and destruction, reducing in size by 50% during the 1960s and 1970s, and remains under threat from illegal activities, human population pressure and climate change. This study is the first to investigate the status and trends of bird communities in the VNP, using a multi-year dataset. We use a five-year dataset, totalling over 3,200 point-counts, both within and around the VNP, to assess the conservation value of the VNP for birds in comparison with other national parks and non-protected areas. We assess bird communities and population trends within and around the parks and identify important habitat factors for birds within the VNP. We found that the VNP hosts a unique bird community compared to other localities, with several Albertine Rift endemics and threatened species occurring in the VNP. Hagenia/ Hypericum woodland, herbaceous vegetation, brush ridge and mixed forest host the highest levels of bird diversity in the VNP, whilst the park’s waterbodies provide key habitat for the endangered Albertine Rift endemic Grauer’s Swamp-warbler (Bradypterus graueri). Elevation had a negative effect on bird diversity in the VNP, whilst the basal area of dead trees, Hagenia and vines had a positive effect. Both inside and outside the VNP, there was a significant decline in abundance and species richness over the sampling years; however, we advocate for further monitoring to confirm these trends. Based on our findings, we recommend effective, targeted management of key habitats for birds within the park, including those identified in this study, in order to mitigate bird declines and conserve the unique bird communities in the VNP.

AbstractIn the relatively small area of the National Park (NP) „Kopaonik“ a lot of exogenous and endogenous processes took part and continue to act until present day. In this paper are presented the geotouristic resources evaluation results for six geosites in the NP „Kopaonik“. The experts on this field gave their assessment in three versions. The first one is concerned with the evaluation of the educative contents, the second one is concerned with the evaluation of geotouristic values, while the third version, which is based on the Modified Geosite Assessment Model (M-GAM) offers the assessment regarding education, aesthetic significance, protection, functional and touristic values. The M-GAM method takes in consideration the opinion of visitors along with the estimation of subindicators given by experts, on whom relies the previous two versions. The include of visitors in the evaluation process leads to more objective estimations. Results obtained by this study can be useful for the improvement and planning of touristic activities on geosites because, bearing in mind their significance for the tourists, they indicate on the lower values that require more attention in the future.

We describe five new species of Miconia (Melastomataceae) from Yanachaga Chemillén National Park and vicinity in Pasco, Peru: Miconia cardenasiae, Miconia chemillensis, Miconia humifusa, Miconia odoratissima, and Miconia pozuzoana. These species occur across a range of ecological habitats in the central Andes of Peru. Two of these species exhibit modifications for plant-arthropod interactions as leaf domatia and one of them has hollow stems. The number of previously undescribed species presented here from a relatively small area underscores the continued need for alpha taxonomy in the tropical Andes. Based on restricted distribution and habitat degradation pressure, we recommend that all species be categorized as either Endangered or Critically Endangered under IUCN guidelines.
