Migrant Entrepreneurship in Spain: a Systematic Review
Authors: Vitores María , Fernández Mercedes , Caro Raquel
Published: August 2020

Introduction: Spain became an immigrant receiving country in the mid-nineties of the 20th century, when foreign workers started arriving, attracted by the booming market for unskilled labour. They traditionally entered the secondary market as employees, showing a self-employment rate lower than that of natives. However, during the economic downturn, ethnic businesses significantly increased, adopting new strategies and proving the resilience of immigrant entrepreneurs.Method: This paper aims to gather peer-reviewed literature to investigate migrant entrepreneurship in Spain, and its implications in immigrant’s performance in the labour market. Thirty-nine papers met the criteria.Results: Results show that migrant entrepreneurs: (1) respond to necessity and opportunity (2) are mainly focused on open market, rather than on ethnic business; (3) seek support in transnational practices.Discussion and/or Conclusion: Our analysis shows that Spanish migrant entrepreneurs’ behavior is not fully fitting into the classical theoretical frameworks and that in general there is a certain overlapping or a new model arising. In fact, the crisis has brought changes to ethnic minority businesses and their vulnerability with higher turnover. But it also has brought opportunities, innovation, new niches, transnational focus, and certain ease in access to property.
El enclave palestino en la Ciudad de Guatemala
Authors: Kayayan Vicken
Published: August 2020

Introducción: Pese a haberse instalado en uno de los países más desiguales de Latinoamérica, los migrantes palestinos en la Ciudad de Guatemala experimentaron una movilidad económica ascendente. A partir del comercio de importación de productos textiles, los palestinos lograron colocarse como proveedores clave para el mercado popular guatemalteco. Dicha actividad económica se ha llevado a cabo, principalmente, en las calles 17, 18 y 19 y en la sexta avenida de la zona 1, área urbana dedicada al comercio de mayoreo y de importación. El presente artículo tiene como objetivo analizar el proceso de incorporación económica de los migrantes palestinos al sistema económico guatemalteco. Por un lado, se examina la estructuración del grupo en torno al comercio y, por otro, se identifican las implicaciones que conlleva dicha actividad económica.Metodología: La investigación está basada en diversos datos etnográficos (etnografía de redes y varias entrevistas con migrantes, representantes de entidades y personas de ascendencia palestina) recabados durante el 2018 en la Ciudad de Guatemala.Resultados: Los datos indican que los palestinos se han incorporado al sistema económico guatemalteco por medio de un “enclave migrante” (Portes, 2014; Portes y Böröcz, 1989; Portes y Manning, 2013). En efecto, los migrantes controlan un nicho económico en particular (que les posiciona como proveedores clave de productos textiles para el comercio popular) y sus almacenes están situados en una misma zona geográfica. Además, el éxito de sus actividades económicas depende de las redes comunitarias y transnacionales, así como de distintas formas de solidaridad entre los miembros del grupo.Discusión: El caso de los comerciantes palestinos en Guatemala demuestra que, si bien el enclave puede ser eficiente, económicamente exitoso y contribuye al desarrollo del país de origen; también puede llevar al grupo a situaciones contrarias, tales como el aislamiento social.
Comparación de inmigrantes y autóctonos en la experiencia del conflicto intergeneracional
Authors: Calín-Navarro María Verónica , Vera-Martínez Juan J.
Published: August 2020

Introducción: Los inmigrantes de segunda generación han de afrontar el proceso de aculturación viviendo en un país distinto al de sus progenitores; y a la vez experimentar los conflictos que surgen en la adolescencia (vinculados a la identidad, sentido de pertenencia y socialización de valores). Esto puede poner en jaque la convivencia familiar, potenciando discrepancias en temas como educación, expectativas, noviazgo o relaciones familiares. Se comparan las percepciones de las relaciones y conflictos con los progenitores entre jóvenes autóctonos e inmigrantes de segunda generación.Método: Se usa una encuesta para indagar tales diferencias relativas a discrepancias/ajustes intergeneracionales. 127 jóvenes “autóctonos” y 77 “inmigrantes de segunda generación” responden individualmente en una sesión de clase a cuestionarios sobre conflicto intergeneracional percibido (ICI, Chung, 2001) y vínculo padres e hijos (IPPA, Armsden y Greenberg, 1989).Resultados: Se encontraron diferencias significativas entre grupos de autóctonos / inmigrantes en aspectos relacionados con las creencias, las relaciones y el tiempo en familia. Pero no en otros aspectos que mostraban mayor grado de conflictividad relacionados con la educación o el noviazgo. Además, las relaciones vinculares entre jóvenes y progenitores no se dan igual para madres y padres, reflejando diferencias en dimensiones que son significativas. Los/las jóvenes inmigrantes empiezan a sentirse españoles (aunque no uniformemente), sintiéndose más identificadas con España que con el país originario de sus progenitores.Discusión y/o Conclusión: El conflicto intergeneracional presenta diferencias entre autóctonos e inmigrantes, aunque no generalizadas ni uniformes. La calidad de las relaciones padres-hijos muestra mejor relación en autóctonos sobre inmigrantes, y en madres sobre padres, aunque esto sucede en distintas dimensiones de la relación. El impacto de la aculturación en la relación/conflicto intergeneracional refleja tendencias e indicadores que deben seguir siendo investigados, en la medida que pueden condicionar la adaptación familiar y socialización en inmigrantes de segunda generación.
Trabajadores fronterizos en Europa: causas y consecuencias de un fenómeno en expansión
Authors: Viruela Rafael
Published: August 2020

En Europa, más de dos millones de personas trabajan en un país y residen en otro, al que regresan cada día o, al menos, una vez a la semana. El artículo hace un balance general de estos desplazamientos, de su distribución geográfica, de los factores que contribuyen a la movilidad transfronteriza, de los obstáculos que impiden que alcance mayor amplitud y de sus consecuencias. Esta investigación se apoya en la información estadística proporcionada por Eurostat y la Comisión Europea y en los resultados de estudios realizados en diferentes países. El aumento de la movilidad fronteriza se relaciona, entre otros factores, con la ampliación de la Unión Europea y el derecho de libre circulación de trabajadores, la proximidad geográfica y las diferencias económico- laborales entre el lugar de trabajo y el de residencia. Las idas y venidas aumentan con rapidez en los países poscomunistas, que destacan como exportadores de mano de obra. La oferta de empleo se concentra en Europa central, sobre todo en Alemania, Suiza, Luxemburgo y Austria.
Particle Swarm Optimization on Parallel Computers for Improving the Performance of a Gait Recognition System
Authors: Abdulqader Shahla A. , Krekorian Hasmek A.
Published: August 2020

In recent years, the gait recognition (GR) using particle swarm optimization (PSO) algorithm (OSO) has been execute very fast and accurate with single computer, but with the appearance of parallel computing (PC), it was necessary to use this technique to improve the results of GR. This study presents the use of parallel computing approaches (PCA) to implement PSO for a GR system (GRS) to decrease processing while maintaining reconstructed image quality. These approaches are: Codistributor and parallel cluster. Many experiments have been executed with recognition between the two approaches. The experimental results showed that increasing the PSO swarm size, decreasing number of iterations, and increasing number of workers used for the PCA can reduce recognition time and increase performance. Best results were obtained from implementing parallel computing with eight workers and 100 iterations. The execution time reached 4s and PSNR reached 44db. At the same time, the best results were obtained from PCL approach.

Denture Stomatitis: Report of a Case with Rarely Used Treatment Modality and Review of Literature
Authors: Parul Uppal Malhotra  , Neera Ohri  , Yagyeshwar Malhotra  , Anindita Mallik
Published: August 2020

Candida albicans is the most common Candida species isolated from the oral cavity both in healthy and diseased. Candida albicans is a dimorphic fungus existing both in blastopore phase (yeast phase) and the hyphal or mycelial phase. Although these organisms typically colonize mucocutaneous surfaces, the latter can be portals of entry into deeper tissues when host defences are compromised. Denture stomatitis is a common form of oral candidiasis that manifests as a diffuse inflammation of the maxillary denture bearing areas & is associated with angular cheilitis. At least 70% of individuals with clinical signs of denture stomatitis exhibit fungal growth & these conditions most likely result from yeast colonization of the oral mucosa combined with Bacterial colonization. Candida species act as an endogenous infecting agent on tissue predisposed by chronic trauma to microbial invasion. At one time, oral fungal infections were rare findings in general dentist's office. They were more commonly seen in hospitalized and severely debilitated patients. However with enhanced medical and pharmaceutical technology, increasing numbers of ambulatory immunosuppressed individuals with oral fungal infections are seeking out general dentists for diagnosis and treatment of these lesions.
Health Literacy: Addressing Well-Being: A Review
Authors: Faisal Noor Ahmad  , Ravishankar TL  , Amit Tirth  , Parmieka Rawat
Published: August 2020

Literacy forms an important input in overall development of individual enabling them to comprehend their social, political and cultural environment better and respond to it. Health literacy requires knowledge of health topics. People with limited health literacy often lack knowledge or have misinformation about the body as well as the nature and causes of disease. Without this knowledge, they may not understand the relationship between lifestyle factors such as diet and exercise and various health outcomes. Health literacy plays a key role on the overall health and wellbeing and is now recognized as a determinant of health and has been made a priority of public health agendas, as there is existence of clear scientific evidence regarding its association with health outcomes such as use of health care services, hospitalizations, mortality rates, and adherence to treatment regimens. Therefore, responsive health system that eliminates barriers to clear communication and provides usable and actionable health information and services is important to uplift the current situation.
What Normativity Cannot Be
Authors: Bedke Matthew
Published: August 2020

Here, I consider Derek Parfit’s Normativity Objection to naturalist realism, according to which normative-natural property or fact reductions are “conceptually excluded”. While a lot of philosophers inclined toward non-naturalism share this view or something close to it, plenty of philosophers remain unconvinced, and the literature offers little guidance to the perplexed. I suggest a way to improve the argument – indeed, I think it is the best and perhaps only plausible way to make good on the claim of conceptual exclusion. But the improved argument relies on the highly controversial claim that normative cognition is transparentin the following sense: normative concepts reveal the nature of the properties they aim to ascribe. This nature, the argument continues, is inconsistent with naturalist strictures.
The Normative Pluriverse
Authors: Eklund Matti
Published: August 2020

According to a certain pluralist view in philosophy of mathematics, there are as many mathematical objects as there can coherently be. Recently, Justin Clarke-Doane has explored what consequences the analogous view on normative properties would have. What if there is a normative pluriverse? Here I address this same question. The challenge is best seen as a challenge to an important form of normative realism. I criticize the way Clarke-Doane presents the challenge. An improved challenge is presented, and the role of pluralism in this challenge is assessed.
Moral Outrage Porn
Authors: Nguyen C. Thi , Williams Bekka
Published: August 2020

We offer an account of the generic use of the term “porn”, as seen in recent usages such as “food porn” and “real estate porn”. We offer a definition adapted from earlier accounts of sexual pornography. On our account, a representation is used as generic pornwhen it is engaged with primarily for the sake of a gratifying reaction, freed from the usual costs and consequences of engaging with the represented content.We demonstrate the usefulness of the concept of generic porn by using it to isolate a new type of such porn: moral outrage porn. Moral outrage porn is representations of moral outrage, engaged with primarily for the sake of the resulting gratification, freed from the usual costs and consequences of engaging with morally outrageous content. Moral outrage porn is dangerous because it encourages the instrumentalization of one’s empirical beliefs and one’s moral beliefs, manipulating their content for the sake of gratification. Finally, we suggest that when porn is wrong, it is often wrong because it instrumentalizes what ought not to be instrumentalized.
The interaction effect and optimal formulation of selected polyherbal extracts towards antioxidant activity
Authors: Rahim N.F.A. , Muhammad N. , Abdullah N. , Talip B.A. , Poh K.H.
Published: August 2020

Past study showed that lemongrass (Cymbopogon citratus), curry leaves (Murrya
koenigii), turmeric (Curcuma longa) and ginger (Zingiber officinale) contain
phytochemicals associated with antioxidant properties. However, all the herbs are tested
individually and rarely mix together. This study was conducted to examine the antioxidant
properties and interaction effect when combined. The plants studied were decocted with
distilled water. Eighteen formulations of aqueous extracts were established using simplex
lattice mixture design that was generated by Design Expert software. The antioxidant
properties were analyzed by 2-diphenyl-2-picryl hydrazyl radical scavenging (DPPH),
ferric reducing antioxidant power (FRAP), total phenolic content (TPC) and total
flavonoid content (TFC) assays. The result showed that the mixture of lemongrass and
curry leaves extracts gave the highest reading in DPPH assay (91.14%), FRAP assay
(215.66 mM) and TFC (22.62 µg Rutin/mL). In the DPPH assay, the ratio of one to one
(1:1) mixture of lemongrass with other plants extracts showed antagonistic interaction.
There were five (5) formulations that showed synergistic interaction in all assays.
However, there were two (2) formulations that showed antagonistic interactions on both
DPPH and FRAP assays. No additive effect was observed in all formulations. The
suggested optimum formulation contains 53.7% lemongrass, 43.4% curry leaves, 2.9%
ginger and 0.0% turmeric. Most of the mixtures presented synergistic interactions. This
indicated the potential of plant extract mixtures to be developed into nutraceutical
products in the future by conducting in-vivo study.
Novel Interventions for Non-Compressible Torso Hemorrhage: Secondary Considerations in Consequences of Aortic Occlusion
Authors: Bonanno Alicia M , Ross James D
Published: August 2020

Non-compressible torso hemorrhage in trauma remains a leading cause of death in austere environments. Advancements for treatment include resuscitative endovascular balloon occlusion of the aorta (REBOA), selective aortic arch perfusion (SAAP), and external compression approaches (junctional tourniquets and abdominal aortic tourniquets), which have provided several promising avenues. However, the application of these devices carries the risk of distal ischemia and the consequences associated with reperfusion injury. This review aims to look at these novel interventions and the physiologic burden associated with them. Following a review of these new advents, we will evaluate the possible solutions to reverse the physiologic penalties.
Isolated Abdominal Injury of Blunt Aortic Trauma: Two Case Reports and Review of the Literature
Authors: Raguan Barak , Shnaker Ali , Fajer Simone
Published: August 2020

Background: Injury to the abdominal aorta as part of a blunt injury is a rare event and is normally associated with other abdominal injuries. The management of these injuries can be non-operative, open repair or endovascular repair.Methods: We present two cases of blunt abdominal aortic injury (BAAI) in which the aorta was the only abdominal injury. This is followed by a review of the current literature.Results: Both these cases were treated endovascularly with good results. Conclusions: BAAIs are rare and can occur in isolation, i.e. without any accompanying abdominal injuries. Despite historically being treated mostly by open repair, endovascular repair offers many advantages and can be safely managed.

Endovascular Resuscitation for Ruptured Abdominal Aortic Aneurysms with Main Stent-Graft and REBOA via Single-Sided Access
Authors: McGreevy David , Hörer Tal M , Pirouzram Artai
Published: August 2020

Background: Aortic balloon occlusion or resuscitative endovascular balloon occlusion of the aorta (REBOA) for hemorrhage control during endovascular aortic repair (EVAR) is a technique that has been used for decades for ruptured  abdominal aortic aneurysms (rAAA). This usually requires bilateral femoral access, however, when only single-sided vascular access can be obtained this complicates the procedure if these techniques are to be used. We present two cases of single-sided vascular access, recently performed at our institution, using simultaneous REBOA and aortic stent-graft placement during EVAR in rAAA. Method: This is a description of two clinical cases where REBOA and EVAR were performed through single-sided vascular access for the treatment of rAAA at Örebro University Hospital between March 2018 and June 2018. Conclusion: This case report demonstrates that despite the limitation of single-sided access, an aortic stent-graft can be placed for treatment of a rAAA during continuous aortic occlusion with REBOA, facilitated by using a multidisciplinary EndoVascular resuscitation and Trauma Management (EVTM) team approach.

Published: August 2020

Strengthening buildings can minimize the earthquakes’ life safety risk. Wellington has around 800 office buildings that might have structural and non-structural seismic vulnerabilities. Given a limited budget and other constrains, prioritization of retrofitting buildings has become a fundamental topic for decision makers. Different methods have been developed to define prioritisation strategies of retrofitting building on a wide territorial scale. In this paper, we applied the multi-criteria decision making (MCDM) analysis to define different propriety ranking able to satisfy different purpose. Moreover, Fuzzy TOPSIS and VIKOR are two MCDM methods are applied to compare the results. In order to help decision makers in choosing the optimal mitigation strategy with multidimensional perspective, different political and social scenarios are also defined. Based on available seismic risk information (vulnerability, seismic hazard, exposure) the prioritization can be identified. Our aims are: (1) to describe the priority scenarios based on the seismic risk. (2) to rank retrofitting buildings based on different purpose. (3) to relate these findings to possible lessons for policy makers when designing retrofit building strategies.

Flood risk assessment and scenarios for a flood insurance program in central Vietnam EGU2018
Authors: Hoang Thoa , Zuanon Magali , Vu Tu , Ranzi Roberto
Published: August 2020

Severe floods occur in several coastal area of Vietnam and causes both properties and causalities. It is important to guide local households in selecting risk management strategies according to their capacity to reduce significant damage (Molinari et al). Insurance was recently recognized as one of the possible non structural measures to mitigate losses and damages from natural disasters (UNISDR, 2015). Despite the huge effect on citizens' life from flood risk and believable higher damages caused by flood in the future due to climate change, it is surprising that there is no flood insurance program in Vietnam. This paper investigates the vulnerability of households to flood and suggests a conceptual framework to implement possible scenarios of flood insurance programs for Central Vietnam. We implement 2D simulations of the physical hazard in term of flooding, velocity, depth and duration, and then combined the flood hazard maps, exposure and vulnerability maps to obtain risk maps. We calculate major flood damages, regarding housing damages and paddy rice damages, for five different return periods (10, 20, 50, 100, 200 years). Based on 386, out of 400 responses to 35 questions in a questionnaire directly related to flood risk and preparedness, the vulnerability curve for direct tangible costs to building structure, building contents, and paddy rice were assessed. We also find that, in the long term, with a proper flood insurance premium, three actors (Vietnam Government, insurance companies, and local households) could all achieve their targets. Local households are insured by insurance contracts against flood losses with a reasonable insurance premium. Vietnam Government might reduce its budget for subsidising local households after flooding by transferring flood risk to insurance companies. Insurance companies might make profits in long term as this market has a potential growth in Vietnam. One more important contribution of this paper is that this measure could guide land planning toward decisions which tend to minimize the total flood losses

© 2018 Intertidal rocky shore ecosystems are affected by steep environmental gradients such as fluctuating solar irradiation and salinity along the marine-terrestrial interface. The eulittoral red alga Pyropia plicata (Bangiales) is endemic and abundant to coastal regions of New Zealand and almost unstudied in terms of ecophysiological performance under radiation and salinity stress. Therefore, the acclimation potential of this species against enhanced ultraviolet radiation (UVR) and osmotic stress was evaluated in a combination of field and laboratory experiments with an emphasis on stress metabolite concentrations (UV-sunscreens, organic osmolytes). Samples of P. plicata were collected at the same site in the intertidal zone of Wellington, New Zealand over three seasons (April–November 2016) and used in independent UV and salt stress experiments under controlled conditions. The mycosporine-like amino acids (MAA) shinorine and porphyra-334 were the quantitatively dominant UV-sunscreen compounds, and the total concentrations varied over the year between 5 and 14 mg g−1 dry weight (DW), but neither UVR nor PAR had a significant impact on the total or individual MAA concentrations. A UV radiation stress experiment was conducted, but the total MAA concentrations of 6–8 mg g−1 DW did not change, neither did the contents of shinorine (~ 3 mg g−1 DW) nor that of porphyra-334 (4–5 mg g−1 DW). This suggests, that P. plicata has sufficiently high UV-sunscreen amounts and hence does not respond to changes in UV radiation. Pyropia plicata contained three heterosides (floridoside, D- and L-isofloridoside), which act as organic osmolytes. Seasonally the total concentrations of these compounds varied between 203 and 1226 mmol kg−1 DW, with L-isofloridoside quantitatively dominating all samples. A salt stress experiment showed an increase in the total heteroside concentrations in P. plicata with increasing salinities. However, floridoside was the most up-regulated heteroside under hypersaline conditions indicating its key role in osmotic acclimation. Our data indicate that P. plicata always contains various stress metabolites in consistently high concentrations which mitigate against environmental changes typical of the intertidal zone of New Zealand.

© 2017 Japanese Society of Phycology The discovery of a plethora of cryptic species in many algal groups has led to speculation as to the causes of this observation and has affected taxonomy, with reluctance to give names to species that look identical. While this is defensible for monophyletic cryptic species complexes, both our understanding of similar morphologies (crypsis) and nomenclature is challenged when we encounter non-monophyletic ‘cryptic’ species. Bostrychia simpliciuscula is a wide-ranging species in which multiple cryptic species are known. Our increased sampling shows that this species consists of four lineages that do not form a clade, but lineages are sister to species with different morphologies. Careful morphological examination shows that characters, especially branched monosiphonous laterals and rhizoid morphology in haptera, are able to distinguish these four lineages into two groups, that are still not monophyletic. The similar morphologies in these lineages could be due to convergence, but not developmental constraints or lack of time to diverge morphologically; or possibly maintenance of a generalized body plan. These lineages appear to have specific biogeographic patterns and these will be used to propose a new taxonomy. B. simpliciuscula is now confined to the tropics. Another of these lineages matches a previously described species, B. tenuissima, that was synonymized with B. simpliciuscula and is from cold temperate Australasia, and is resurrected. Another lineage is found in Japan in which a previous name is also available, B. hamana-tokidae; the last lineage is found in central New South Wales, morphologically it resembles B. tenuissima, with which it overlaps in distribution around Sydney, and is named as a new species, B. kingii sp. nov.

© 2017 The Korean Society of Phycology. Geographic distributions of pathogens are affected by dynamic processes involving host susceptibility, availability and abundance. An oomycete, Pythium porphyrae, is the causative agent of red rot disease, which plagues Pyropia farms in Korea and Japan almost every year and causes serious economic damage. We isolated an oomycete pathogen infecting Pyropia plicata from a natural population in Wellington, New Zealand. The pathogen was identified as Pythium porphyrae using cytochrome oxidase subunit 1 and internal transcribed spacer of the rDNA cistron molecular markers. Susceptibility test showed that this Pythium from New Zealand was able to infect several different species and genera of Bangiales including Pyropia but is not able to infect their sporophytic (conchocelis) phases. The sequences of the isolated New Zealand strain were also identical to Pythium chondricola from Korea and the type strain from the Netherlands. Genetic species delimitation analyses found no support for separating P. porphyrae from P. chondricola, nor do we find morphological characters to distinguish them. We propose that Pythium chondricola be placed in synonymy with P. porphyrae. It appears that the pathogen of Pyropia, both in aquaculture in the northern hemisphere and in natural populations in the southern hemisphere is one species.

© 2016 International Phycological Society. Sympatric coexistence of cryptic species, indistinguishable morphological taxa, has increasingly been detected on the basis of molecular data. This discovery raises the interesting question of how cryptic species can coexist, as hypothetically they would need identical ecological resources. The red alga Bostrychia intricata is commonly found along New Zealand shores. Previous studies indicated several cryptic species within this morphospecies, and that some populations have multiple species. This study aimed to determine how coexisting cryptic B. intricata distribute at a small scale. Along the shore of Moa Point, Wellington, we conducted intensive sampling of B. intricata in different habitats with respect to tidal position, wave and sun exposure levels. Our genetic data clearly documented the coexistence of three cryptic species of B. intricata: N2, N4 and N5. Multiple samples from individual algal patches indicated that each patch was made of the same ramet. Our analyses revealed a habitat-related pattern in small-scale distribution of different cryptic B. intricata, suggesting that the distribution of these cryptic species was not random. Cryptic species N4 was found at a higher tidal position than species N2 and N5, whereas cryptic species N2 occurred in more wave-exposed areas than the other species. Discriminant analysis indicated that tidal height strongly influenced the distribution pattern among these cryptic species. Our observations demonstrated that the co-occurrence of three cryptic B. intricata can partly be explained by their occupation of different intertidal habitats, highlighting the nonrandom distribution of coexisting cryptic algal species.

© 2017 Phycological Society of America Wittrockiella is a small genus of filamentous green algae that occurs in habitats with reduced or fluctuating salinities. Many aspects of the basic biology of these algae are still unknown and the phylogenetic relationships within the genus have not been fully explored. We provide a phylogeny based on three ribosomal markers (ITS, LSU, and SSU rDNA) of the genus, including broad intraspecific sampling for W. lyallii and W. salina, recommendations for the use of existing names are made, and highlight aspects of their physiology and life cycle. Molecular data indicate that there are five species of Wittrockiella. Two new species, W. australis and W. zosterae, are described, both are endophytes. Although W. lyallii and W. salina can be identified morphologically, there are no diagnostic morphological characters to distinguish between W. amphibia, W. australis, and W. zosterae. A range of low molecular weight carbohydrates were analyzed but proved to not be taxonomically informative. The distribution range of W. salina is extended to the Northern Hemisphere as this species has been found in brackish lakes in Japan. Furthermore, it is shown that there are no grounds to recognize W. salina var. kraftii, which was described as an endemic variety from a freshwater habitat on Lord Howe Island, Australia. Culture experiments indicate that W. australis has a preference for growth in lower salinities over full seawater. For W. amphibia and W. zosterae, sexual reproduction is documented, and the split of these species is possibly attributable to polyploidization.
