Six annual single-pass roadkill surveys along two adjoining rural Queensland highways near Carnarvon Gorge National Park revealed 612 medium-size to large vertebrates, representing more than 18 taxa. Most were mammals (92%), particularly macropods. Losses averaged 0.26 animals km–1 year–1 (range = 0.17–0.33), with variation possibly reflecting road repair/reconstruction and record seasonal rainfalls. Annual roadkill totals for the 390-km highway were projected to be over 5000 vertebrates, with more than half being large macropods. A consistent hotspot or ecological trap was noted along a 17-km high-traffic-volume stretch north of Roma. Because the sparsely populated outback is habitat for much Australian wildlife, multiyear baseline data are vital to identify the magnitude of the problem and inform future research.

We present molecular evidence for the presence of two species morphologically similar to Spinomantis bertini in Andohahela National Park, south-eastern Madagascar, differing by 5.5−6.3% pairwise DNA sequence divergences in the mitochondrial 16S rRNA gene. One of these was observed at higher elevations of ca. 1650 m above sea level, whereas the other was found at lower elevations of ca. 715 m a.s.l., close to the type locality of S. bertini (Isaka-Ivondro), and in one other location (Andreoky, ca. 1050 a.s.l.). We herein assign these low- to mid-elevation specimens to S. bertini based on their occurrence near the type locality and general agreement in colour pattern with the type specimen of Gephyromantis bertini Guibé, 1947. The high-elevation form is described as Spinomantis beckei sp. nov. based on its molecular divergence and reciprocal monophyly with respect to S. bertini, lower expression of greenish dorsal colour and less distinct frenal stripe. Based on a comparison of published call descriptions for S. bertini and our recordings of S. beckei, we hypothesize that S. bertini has a lower note repetition rate in advertisement calls. Molecular data suggest that the S. bertini species complex is more diverse than previously recognized, with at least two more candidate species identified: S. sp. Ca7 from Ranomafana National Park, and a newly identified candidate species S. sp. Ca12 from Pic d’Ivohibe Special Reserve.

Despite a recent surge of visitation and frequent media accounts of lawlessness in America’s national parks, little empirical research has been dedicated to crime and law enforcement in the U.S. national park system. The absence of systematic crime and justice research within these protected spaces should raise concern, as recent park service data and intra-agency reports suggest visitor growth, funding and personnel declines, operational shortcomings, and technology constraints may endanger the capacity of the National Park Service (NPS) to adequately address anticipated crime threats in the 21st century. This call for research aims to raise awareness of the contemporary law enforcement challenges facing this federal agency and encourage the study of crime and justice issues within the U.S. national park system. We briefly examine the evolution and current state of NPS law enforcement and its associated challenges and conclude with a conceptual road map for future research occurring in these protected spaces.

Abstract Although perceived value is considered essential in any marketing activity, the role it plays regarding the relationship between perceived risk and loyalty in the context of organizational markets is not thoroughly considered. Therefore, this paper addresses the aforementioned issues in the context of the small and medium size enterprise market in Romania. From a sample of 229 entities, data were collected and analysed using structural equation modelling techniques. Results confirmed that different relationships are established between functional or financial risk and emotional value on the one hand, and emotional value and loyalty on the other hand. Discussions of the results integrate main findings with other studies that partially or tangentially study the connections between emotional value, risk and loyalty. The paper end with a brief limitations and avenues for future research.

Multiplier Effects

Numerous studies have explored design and evaluation of bus lane priority by using empirical, analytical, and simulation approaches. However, none attempted to understand how different bus lane combinations, such as continuous and discontinuous bus lane sections, and a different number of bus lane sections, affect bus performance and general traffic. This paper investigates operational effects of bus lane combinations to establish whether multiple bus lane sections create a multiplier effect in which a series of continuous bus lane sections creates more benefits than several single-lane sections. If a multiplier effect exists, it suggests scale economies in wider implementation of bus priority on a networkwide scale. Overall, results confirm that there is a multiplier effect; thus bus travel time benefits and general traffic travel time disbenefits are proportional to the number of links with a bus lane. The effect suggests a constant return to scale on continuous multiple sections. The results also suggest that converting a traffic lane to a bus lane when the upstream traffic volume exceeds the capacity of the remaining traffic lanes causes significant negative effects for buses and general traffic. In addition, negative general traffic effects of continuous bus lane combinations are lower than those for a similar number of discontinuous bus lanes. Bus delays at intersections approaching the bus lane tend to improve when upstream traffic volume does not exceed the capacity of remaining downstream traffic lanes. Policy implications and areas for future research are suggested.

Raptors are wide-ranging, vagile avian predators whose populations can be difficult and costly to monitor on their breeding or winter range. However, monitoring raptors during their annual northbound or southbound migration is a cost-effective and efficient alternative to time-intensive, single-species breeding surveys. In 2010, we observed numerous Swainson’s Hawks (Buteo swainsoni) and Red-tailed Hawks (Buteo jamaicensis) migrating through the Hayden Valley in central Yellowstone National Park, prompting an investigation into raptor migration patterns in the park. Our objectives were to monitor annual autumn raptor migration in Hayden Valley from 2011 to 2015 and to determine the relative role of this undocumented migration site by comparing our observations to simultaneously collected migration data from three other sites in the Rocky Mountain Flyway. From 2011 to 2015, we observed 6441 raptors of 17 species across 170 d and 907 h of observation. Red-tailed Hawks, Swainson’s Hawks, and Golden Eagles (Aquila chrysaetos) accounted for 51% of the total individuals observed over five years. Overall counts from Hayden Valley were comparable to counts from the three migration sites in the Rocky Mountains, although abundance of individual species varied by site. Data from this study suggest that Hayden Valley may serve as a stopover site for migrating raptors and presents an opportunity for future research. By improving our understanding of where raptors migrate and the characteristics of stopover areas in the Rocky Mountains, land managers may develop effective strategies for protecting raptor populations and habitat from threats including development and climate change.

Purpose This paper aims to construct an assessment framework to establish a maturity model for Web Electronic Services offered at a local government level and investigate the maturity of Greek municipalities in the E-Government field, trying to correlate how this is affected by demographic variables. Design/methodology/approach An original assessment framework regarding municipal Electronic Services was created based on the literature review. The assessment framework was included in a methodological approach supported by the PROMETHEE II method, as well as by selected statistical methods. The framework and the methodological approach were applied in the case of Greek municipalities. Findings The analysis revealed the low maturity level of Greek municipalities in Electronic Services sector. The Greek case study indicated that the proposed framework and methodological approach could provide useful insights to municipalities for the improvement of its E-Government Web services based on their strategic preferences. Research limitations/implications The assessment took place only in Greece, assessing all the country's municipalities and conducting research only in the municipalities’ websites. The proposed methodology suggests that the PROMETHEE II multi-criteria decision analysis method can support the assessment of the maturity level of local government entities. Moreover, the combination of the PROMETHEE II–empowered assessment framework with demographic statistical analysis can assist orthological decision-making concerning future investments in Web Electronic Services. The methodology could be a good option for future research efforts (assessments) in municipalities, in Greece and worldwide. Practical implications The framework is both easy to use and fairly complete. The fact that the assessment was conducted in all the Greek municipalities makes it much more reliable, as it provides the whole picture. The suggested methodology which includes the proposed framework could be used in the cases of municipalities in other countries to assist future actions concerning the investment in Web Electronic Services. Originality/value This study provided a medium-size framework, being both complete and easy to use during the evaluation process of all the municipalities in Greece. In addition, the statistical analysis received data from a decision-making tool to execute the clustering (Cluster analysis is usually performed based on the raw data).

Constructed in 1930 and recently designated as a National Historic Civil Engineering Landmark, the 1.1 mile long Zion–Mt. Carmel Tunnel has served Zion National Park in Utah well for several decades. With the passage of time, however, vehicles have become larger and this has necessitated the use of one-way operation to allow large vehicles to pass through the narrow tunnel. In recent years the number of visits to National Parks in the Colorado Plateau region has greatly increased. For example, visits to Zion National Park increased by 69% from 2010 to 2017. Accompanying the increase in visitor numbers has been an increase in traffic volume. As traffic volume has grown, two questions have become more obvious: What is the highway capacity of the Zion–Mt. Carmel Tunnel? And, how soon will the tunnel reach capacity? This paper covers a unique traffic engineering/highway capacity problem and describes: (a) the current method of operating the tunnel (both two-way and one-way operation); (b) data collection and analysis; (c) how one-way operation degrades tunnel capacity; (d) calculation of tunnel capacity and waiting times; (e) how soon the tunnel will reach capacity; and (f) alternatives for addressing the capacity problem.
