SUMMARYConservation planning relies heavily on representativeness patterns. In Chile, this has not been assessed at the species level. This study evaluates floristic representativeness in the National System of Protected Areas (SNASPE). Species rarefaction and non-parametric estimators were used to extrapolate total representativeness. Given that conservation planning in Chile is mainly based on protecting vegetation types, the effectiveness of using vegetation types as a surrogate of plant species was evaluated based on richness and complementarity. The study found available information for 42% of the 96 protected areas of continental Chile. According to this information the SNASPE protects at least 48% of the native vascular flora. The southern area protects the largest number of species, most of which are non-endemic natives. The largest number of endemic protected species was found in the central-northern area. The SNASPE in its full range is projected to protect 64% of the vascular flora of Chile. Richness and complementarity surrogacy analyses showed weak effectiveness of vegetation types as a surrogate of plant species, although complementarity performed slightly better than richness. Surrogacy effectiveness was lower for endemic species, probably due to their narrow distributions that are more easily missed when vegetation types are considered instead.

The present study aims to use systematic conservation planning to analyse and review the national protected areas (PAs) network in Jordan. The analysis included the application of three modules: the environmental risk surface (ERS), the relative biodiversity index (RBI), and the application of Marxan. The methodology was based on using Marxan to achieve solutions for three scenarios for the PAs network. Marxan was applied to the input data, which included vegetation types, distribution of threatened mammals and plants, locations of currently established PAs and other types of designations. The first two scenarios aimed to conserve 4% and 17%, respectively, of each vegetation type, and 10% and 20%, respectively, of the extent of occurrence of threatened mammals and plants. The third scenario aimed to conserve 17% of each vegetation type and 10% of the extent of occurrence of threatened plants and mammals, except for forest and the Hammada vegetation which had the target of 30% and 4%, respectively. The results of the three scenarios indicated that the boundaries of existing reserves should be extended to achieve the conservation targets. Some currently proposed (PAs), such as the Aqaba Mountains, did not appear in any of the solutions for the three scenarios indicating that the inclusion of these sites in the proposed (PAs) network should be reconsidered. All three scenarios highlighted the importance of having conservation areas between the western and eastern parts of the country. Systematic conservation planning is a structured, replicable, transparent, and defensible method for designing PA networks. It allows for finding efficient solutions building on what is currently conserved and minimizing the fragmentation and cost of the proposed solution for conservation areas.

AbstractHydrometers are widely used in industry for liquid density measurement. It is important to achieve rapid and high accuracy calibration for hydrometers. Based on the Archimedes principle, a fully automatic hydrometer calibration system in NIM was designed using Cuckow’s method. The liquid density of n-tridecane (C13H28)is calibrated with 441 g high-purity fused silica ring as the solid density standard. The buoyancy of hydrometer is measured by static weighing system with resolution 0.01 mg. The alignment between liquid surface and hydrometer scale was achieved by the lifting platform with the positioning accuracy of 10 μm. According to the weighing value of hydrometer in air and liquid, the density correction value at different scales is calculated. Hydrometer covering a full range (650–1500) kg/m3can be calibrated without changing the liquid. Taking the calibration data of PTB as reference, the experimental data show that the measurement uncertainty of this system is better than 0.3 division (k = 2).

Abstract This paper compares probabilistic and possibility-based methods for design against catastrophic failure under uncertainty. It studies the effect of the amount of information on the effectiveness of each method. The study is confined to problems where the boundary between survival and failure is sharp. First, the paper examines the theoretical foundations of probability and possibility. It also compares the two methods when they are used to assess the risk of a system. Finally, it compares the two methods on two design problems. A major difference between probability and possibility is in the axioms about the union of events. Because of this difference, probability and possibility calculi are fundamentally different and one cannot simulate possibility calculus using probabilistic models. It is shown that possibility-based methods can be less conservative than probability-based methods in systems with many failure modes. On the other hand, possibility-based methods tend to be more conservative than probability-based methods in systems that fail only if many unfavorable events occur simultaneously. Probabilistic methods are better than possibility-based methods if sufficient information is available. However, the latter can be better if little information is available. A principal reason is that it is easier to identify the most conservative possibilistic model than the most conservative probabilistic model that is consistent with the available information.

Abstract: The Porto Ferreira State Park (PFSP) is located in the State of São Paulo southeastern Brazil, in an intriguing transitional area between the Atlantic Forest and Cerrado - both hotspots of biodiversity - represented mainly by the cerradão (CER), and the seasonal semideciduous forest (SSF), with its alluvial variation vegetation type (riparian forest - RP). Ecotonal areas play an important role in providing ecological and phytogeographic knowledge regarding the flora and vegetation of this region. Despite various studies on the PFSP, knowledge of this region remains fragmented. In this study, we aim to conduct an updated checklist of the PFSP vascular flora, including a compilation of all the studies conducted in this protected area, plus field work carried out by the authors from 2014 to 2017. In addition, given its ecotonal characteristics, we completed a floristic similarity analysis between the PFSP and other floristic surveys that examined the same vegetation types present in this study, to gain a better understanding of their phytogeographic relationships. Overall, 684 species, belonging to 387 genera and 107 families, were recorded. The SSF presented the richest vegetation type (478 species), followed by the CER (418) and the RP (231). The most diverse families were Fabaceae (64 species), Myrtaceae (41), Orchidaceae (39), Rubiaceae (37), Asteraceae (35), Bignoniaceae (26) and Malvaceae (20). Moreover, eight threatened species, at regional and national levels, were found. To date, 412 species have been added to the floristic list produced for the PFSP. The life forms with the highest number of species were trees (286 species), herbs (176) plus shrubs and subshrubs (123). Our research findings indicate floristic patterns with higher levels of similarity among species in geographical proximity, including those in ecotonal areas encompassing different vegetation types. These results rank the PFSP among some of the most species-rich conservation units with seasonal climates, and therefore is of great importance for plant conservation in the southeast of Brazil.

Abstract Protected areas can be parts of larger ecosystems, and land use changes in the unprotected part of the ecosystems may threaten the biological diversity by affecting the ecological processes. The relationship between protected areas and their surroundings has been influential in understanding the role of spatial planning in nature conservation. This article focuses on the problem that Turkey’s protected areas are vulnerable to pressure and threats caused by land use changes. Spatial planning serving as a bridge between nature conservation and land use is the solution for effective nature conservation in Turkey. Thereby, the aim of this article is to develop a conceptual framework which offers spatial planning as an effective tool to bridge the gap between land use change and nature conservation. In this context, first literature review is conducted, and systematic conservation planning, evidence-based conservation planning, bioregional planning and national system planning are presented as effective planning methods in nature conservation. In addition to literature review, official national statistics and Convention on Biological Diversity’s country reports are utilized to shed light on Turkey’s current state. Finally, a conceptual framework is defined, the main differences with the current situation are revealed. The results indicate that an effective planning system for Turkey’s protected areas incorporates a holistic, target-oriented system defining the spatial planning process for protected areas. The spatial planning system to be developed in this context is also used by decision-makers in evaluating the ecological effectiveness of existing plans.

Leaders of nonprofit organizations in the United States must build workforce capabilities to meet increasing demands for services. This single-case study explored strategies nonprofit leaders used to build workforce capability to address increasing service demands. The conceptual lens for this study was the full-range leadership theory. Data were collected through semi-structured interviews with senior executives of a single nonprofit organization located in the Midwestern region of the United States, which included internal organizational and workforce performance data, strategy plans, annual reports internal and external financial documents, and publicly available information. Four major themes related to building workforce capacity emerged from a thematic analysis of the data: (1) an emphasis on employee development, (2) the expansion of technology systems, (3) a concentration on developing a culture of autonomy and trust, and (4) the introduction of processes and measurements. The findings from this study might contribute to positive social change by providing nonprofit leaders with strategies and data to support a deeper understanding of how to effectively build workforce capability to address increasing service demands.
