Assessing the efficacy of direct conservation interventions: clutch protection of the leatherback marine turtle in the Dominican Republic
2014
AbstractThe beaches of Jaragua National Park in the Dominican Republic are the country's last known major nesting site for the leatherback marine turtle Dermochelys coriacea. This nesting aggregation is threatened by widespread illegal egg take, and clutch relocation and artificial incubation have been carried out as protection measures since 1974. We assess the efficacy of such efforts and investigate how artificial incubation may be influencing the success and sex ratios of clutches. We compare hatching success, incubation duration and embryo mortality in in-situ clutches (n = 43) with those incubated artificially at sites in the east and west of the Park (n = 35 and n = 31, respectively)…
Towards sustainable coexistence: People and wild mammals in Baluran National Park, Indonesia
2018
Abstract The paper offers a critical discussion of resource use in a national park, Baluran, in Indonesia. In general, an increasing accept of the need for livelihood security, also for people living in or near natural conservation areas, are challenging traditional systems of national park governance. Finding ways to balance the needs of local populations against the necessity to secure biodiversity and environmental sustainability becomes important, and the main question in our research is how to accommodate an existing society in Baluran without a further negative impact on endangered mammals. Based on common pool resource management and co-management theories and thorough empirical inve…
Application of GPS tracking for monitoring spatially unconstrained outdoor recreational activities in protected areas – A case study of ski touring i…
2018
Abstract New trends in leisure and outdoor recreation show an increased penetration of remote areas and the development of spatially unconstrained outdoor recreational activities. Here we present the application of GPS tracking to monitor a spatially unconstrained recreational activity, using ski touring in the Tatra National Park (TNP) as a study case. Particular focus of the study was the spatial and temporal behaviour of ski tourers with regard to existing management measures implemented in the Park, where recreation is limited to designated zones. The research is based upon empirical data (n = 427 ski touring GPS tracks). ArcGIS and statistics software SPSS were used for spatial and sta…
Diversity of leaf katydids (Orthoptera: Tettigoniidae: Phaneropterinae) of Dzanga-Ndoki National Park, Central African Republic, with selected record…
2013
Forty-four species of Phaneropterinae are recorded from Dzanga-Ndoki National Park in the Central African Republic. Eight species collected within the park are described as new to science: Phlaurocentrum morettoi n. sp., P. paratuberosum n. sp., P. elegans n. sp., Myllocentrum raggei n. sp., Poreuomena sanghensis n. sp., Cestromoecha longicerca n. sp., C. magnicerca n. sp., and Goetia purpurea n. sp. An additional new species from Guinea is described from specimens preserved in the Museo Nacional de Ciencias Naturales of Madrid, Poreuomena huxleyi n. sp. Eurycorypha stylata Stål, 1873 is recorded for the first time from Burkina Faso and Brycoptera lobata Ragge, 1981 from Ivory Coast. The fo…
Secondary metabolites from Pinus mugo Turra subsp. mugo growing in the Majella National Park (Central Apennines, Italy).
2013
In this study, we examined the composition regarding secondary metabolites of P. mugo Turra ssp. mugo growing in the protected area of Majella National Park, which is the southernmost station of the habitat of this species. Both the nonpolar and polar fractions were considered. In particular, the essential-oil composition showed a high variety of compounds, and 109 compounds were detected, and 101 were identified, among which abietane-type compounds have a taxonomic relevance. Abietanes were also isolated from the polar fraction, together with an acylated flavonol and a remarkably high amount of shikimic acid.
El uso de SIG de software libre en una práctica de Biología y Geología de 4º de ESO: los ecosistemas.
2016
Para consolidar el conocimiento del bloque del currículo de Biología y Geología de 4º de la E.S.O. (Educación Secundaria Obligatoria) relacionado con los ecosistemas, hemos desarrollado una metodología docente basada en los Sistemas de Información Geográfica (SIG), en la que el objetivo de los estudiantes es crear un shapefile con atributos espaciales e información ecológica sobre los distintos Parques Nacionales de España mediante su digitalización. Se ejemplifica con el procedimiento concreto del Parque Nacional de Doñana. A través del SIG, con un software gratuito para el centro, se aumenta la interactividad del estudiante con la asignatura, se desarrolla la creatividad y se mejora la ca…
New interesting moss records from the Pollino National Park (Southern Italy).

Some interesting moss records in Pollino National Park, noteworthy protected area of the southern Apennines, are reported. Among them, Mnium spinosum and Brachythecium tommasinii are new to southern Italian peninsula, Grimmia laevigata, G. Montana, G. tergestina, G. trichophylla and Orthotrichum pumilum are new to Basilicata region, and, finally, Campylidium sommerfeltii is rare in southern Italy and little known in Mediterranean area.

Reliability and effectiveness of Ellenberg’s indices in checking flora and vegetation changes induced by climatic variations
2001
Two methods are proposed to assess the significance of time-spanned local variations of Ellenberg’s indicator values in floristic and phytosociological data sets respectively. Both methods are based on frequencies and averages of the indicator values within and among data sets. Main goal of proposed methods is to determine the threshold above which the observed variations are to be considered significant. In order to relate the observed floristic variations to recent climatic changes, attention was focused on the Ellenberg’s indices dealing with the main climatic variables: heliophany, temperature and precipitation. Study-cases from Zannone Island (Pontine Archipelago, Mediterranean region)…
