AbstractInternational and national protection strategies and directives focus mainly on macroscopic organism and attempt to maintain their endangered habitats. However, microscopic communities are also threatened by decreasing biodiversity and many species including freshwater algae can disappear without even knowing they were present in the habitat. Defining rarity of microscopic taxa is not easy. The species’ rarity is based on detailed knowledge of distribution and abundance of species. But only limited information is available about rare algal species especially in a given ecoregion. Reducing the data gaps, here, we present altogether 20 phytoplankton taxa rare in Hungary: three species of Chlorophyceae, eight species of Trebouxiophyceae, two taxa of Euglenophyceae, one-one species of Cyanobacteria, Bacillariophyceae and Mediophyceae and three species of Xanthophyceae. One of them, the Cylindrotheca gracilis is on the Hungarian Red List. Physical and ecological characteristics of standing waters where these species were found as well as their former occurrence all over the world are also reviewed.

Abstract The brown hairy dwarf porcupine Coendou vestitus is a poorly studied Andean species endemic to Colombia. Its current Red List category is contradictory: globally it is categorized as Data Deficient but in Colombia it is categorized as Vulnerable. This contradiction has limited the implementation of conservation programmes. We evaluate the level of rarity of the species and provide consolidated information for a new assessment of its Red List status. We reviewed literature, photographs, and voucher specimens in natural history collections. Using the confirmed records, we estimated the extent of occurrence (EOO) based on the minimum convex polygon and the area of occupancy (AOO) summing the area of grid squares occupied by the species. We found that C. vestitus is very rare, with a small range, low estimated population density, occurrence in only one habitat type and small body size. The species has an EOO of 3,323 km2 and an AOO of 24 km2, based on six confirmed localities, all on the western slopes of the Eastern Cordillera, in the central Andean region of Colombia. Based on the species' rarity, restricted distribution, and threats to its natural habitat, we recommend its categorization as Endangered on the IUCN Red List. This will help delineate research and conservation efforts for this porcupine, which has a highly restricted range and inhabits the threatened Andean forest.

AbstractThis article examines the iconographic programme of the Last Judgement scene depicted in Christ III. A notable feature of the poem’s detailed visual programme is the way in which it provides the audience with a single, panoramic vision that encompasses the divergent perspectives of the blessed and the damned. It is on account of this dual perspective that the poem, through its precise use of language and imagery, presents the audience with a bifocal vision of Christ as King of Kings and Judge of the World, in keeping with the words of Revelation 19:16. A detailed analysis of the poem’s imagery, however, suggests that its portrait of Christ as Judge is not only informed by scripture and exegetical sources, but is also indebted to contemporary visual imagery, particularly the depiction of Christ as Majestas Domini, or Christ in Majesty. As a result, and by approaching the poem’s imagery from an iconological perspective, it is argued that the poet of Christ III had a detailed knowledge of contemporary Christological motifs. Furthermore, a careful analysis of the language used to describe the Judgement scene, and particularly the depiction of Christ as Judge, suggests that the poet intentionally seeks to evoke a range of specific visual images in the mind of his audience in order to amplify the poem’s instructive and penitential aims.

AbstractUpwelling occurs on several coasts of the world, but it has mostly been studied on eastern ocean boundaries. We investigated upwelling on a western ocean boundary for which limited information exists. Using daily in-situ data on sea surface temperature (SST), we found a marked contrast in coastal cooling between July 2014 (pronounced) and July 2015 (weak) at two locations 110 km apart on the Atlantic coast of Nova Scotia, Canada. These findings are consistent with a marked interannual difference in wind-driven upwelling. On the one hand, southwesterlies (which cause upwelling on this coast) were more frequent in July 2014 than in July 2015. On the other hand, Bakun’s upwelling index (which is based on wind data and geographic information) indicated that coastal upwelling was more common and intense in July 2014 than in July 2015, while the reverse was true for downwelling. Interestingly, a strong El Niño event occurred in July 2015, while no El Niño (or La Niña) conditions happened in July 2014. In a recent book evaluating upwelling systems around the world, the system that is the focus of the present study was not included. Therefore, our findings should stimulate future research on upwelling on the Atlantic Canadian coast, in that way helping to further develop the knowledge base for western ocean boundaries.

The current global market forces compel most companies to create an international supply chain. Most of these companies have examined the problems and issues that they encounter during the implementation of this international supply chain. These problems are related to the attitude and culture of people around the world or rooted in the nature of the supply chain. Thus, this study compares the implementation of supply chain management (SCM) in two different countries with different cultures and attitudes. This study highlights the similarities of the problems and benefits of SCM implementation in the two countries. This study identifies the characteristics that are not related to attitude and culture and are rooted in the nature of SCM. A questionnaire was designed and distributed to 600 automotive companies in Malaysia and Iran. Several interviews were conducted to find solutions to the problems. Limited information and the lack of expert employees were identified as the most serious problems, whereas the improvement of warehouse management was identified as an important benefit of SCM implementation. Benchmarking and training courses were the important solutions to these problems. These results reveal that most issues in SCM implementation are rooted in its nature.

 Lowland savannas, covering an area of 2,342 km2, form the third largest ecosystem in Belize yet are unevenly and therefore poorly represented in the country’s protected area system. Based on more than 5,700 herbarium collections, a checklist of 957 species of vascular plants is presented for this ecosystem representing ca. 28% of the Belizean flora, of which 54 species are new records for the country. Of the 41 species of plants known to be endemic to Belize, 18 have been recorded within the lowland savanna, and nine species are listed in The World Conservation Union (IUCN) 2010 Red List of Threatened Species. Of the total savanna ecosystem flora, 339 species are characteristic of the open savanna, whilst 309 and 114 species are more frequent in forest and wetland areas respectively. Most species (505, 53% of the lowland savanna flora) are herbaceous. Although the lowland savanna has been relatively well collected, there are geographical biases in botanical sampling which have focused historically on the savannas in the centre and the north of the country. A brief review of the collecting history of the lowland savanna is provided, and recommendations are given on how future collecting efforts may best be focused. The lowland savanna is shown to be a significant regional centre of plant diversity.

Toxic Reactions

The phototoxicity of polyacetylenes from representatives of the Asteraceae to a broad range of freshwater and marine algal species was observed. In the tests triacetylenes were more toxic than diacetylenes. In addition, a small group of polyacetylenes with terminal alcohol or aldehyde groups were found to be toxic with or without ultraviolet (UV) treatment (300–400 nm). Quantitative tests with Euglena and Valonia indicated toxic reactions with three compounds at concentrations greater than 1 ppm. Considering the toxicity of polyacetylenes to bacteria, fungi, invertebrates, and fish, the present work with plants is further evidence of their general cytotoxic nature.
