Fulltext A new genus and two new species of Southeast Asian Bidessini as well as new synonyms for Oceanian species (Coleoptera, Dytiscidae)

Balke M, Bergsten J, Wang LJ, Hendrich L

Zookeys, 2017.
PMID: 28325968 DOI: 10.3897/zookeys.647.11231

Rompindessus jenisi Balke, Bergsten & Hendrich, gen. n. et sp. n. is described from near Rompin village in West Malaysia. The new genus is characterized by the presence of an occipital line and basal pronotal striae, the presence of a thick anterior bead on clypeus and two-segmented parameres as well as by the absence of basal elytral striae, the absence of sutural line on elytron, the absence of basal epipleural transverse carina, and the absence of longitudinal elytral carina. Moreover, male pro- and mesotarsus appear stout, and distinctly dilated laterally; the pronotum is comparably long and parallel-sided and the colour of beetle conspicuous dark orange. Leiodytes kualalipis Balke, Wang, Bergsten & Hendrich, sp. n. is described from West Malaysia (Pahang) and South Vietnam (Cat Tien). It is well characterized by its large size, elongate body and the form of the median lobe. Limbodessus fijiensis (J. Balfour-Browne, 1944), comb. n. described from Fiji is a new synonym of Limbodessus curviplicatus (Zimmermann, 1927) described from Samoa.

Twenty-six new species of Hoploscopa (Lepidoptera, Crambidae) from South-East Asia revealed by morphology and DNA barcoding

Léger T, Kehlmaier C, Vairappan CS, Nuss M

Zookeys, 2020;907:1-99.
PMID: 32063727 DOI: 10.3897/zookeys.907.36563

Hoploscopa Meyrick (Lepidoptera: Crambidae) is a fern-feeding genus found in montane areas of South-East Asia and Melanesia, eastwards up to the Samoan Islands. It includes sixteen described species, with at least 70 further undescribed species known from scientific collections. An iterative approach including morphological and molecular characters was used in order to explore the diversity of Hoploscopa. The hitherto described species are revised, and descriptions authored by T. Léger and M. Nuss are provided for an additional 26 new species: H. agtuuganonensissp. nov., H. albipunctasp. nov., H. albomaculatasp. nov., H. anacanthasp. nov., H. boletasp. nov., H. cynodontasp. nov., H. danaoensissp. nov., H. gombongisp. nov., H. gracilissp. nov., H. ignitamaculaesp. nov., H. isarogensissp. nov., H. jubatasp. nov., H. kelamasp. nov., H. kinabaluensissp. nov., H. mallyisp. nov., H. marijoweissaesp. nov., H. matheaesp. nov., H. niveofasciasp. nov., H. pangrangoensissp. nov., H. parvimaculasp. nov., H. pseudometacrossasp. nov., H. sepanggisp. nov., H. sumatrensissp. nov., H. titikasp. nov., H. tonsepisp. nov., H. ypsilonsp. nov. Using a protocol specific for the amplification of DNA from old museum specimens, we recovered 101 COI barcodes for all but one of the newly described species, with 76 being barcode compliant (>487 bp). Species delimitation analyses suggest cryptic diversity, with six cases reflecting allopatric divergence, and two further cases found in sympatry.

High frequency of triplicated alpha-globin loci and absence or low frequency of alpha thalassemia in Polynesian Samoans

Lie-Injo LE, Pawson IG, Solai A

Hum Genet, 1985;70(2):116-8.
PMID: 2989152

Most of the population in certain areas of Melanesia have one alpha-globin gene deletion (alpha thal2). It is thought that the high frequencies of alpha thal2 in this population is due to a selective advantage given by malaria infection to carriers of alpha thal2. We are interested in neighboring Polynesia which, although adjacent to Melanesia, has always been free of malaria due to the absence of the vector anopheles. We studied 60 Polynesian Samoans and 150 Malaysians by restriction endonuclease gene mapping using Eco RI, Bam HI, and Bgl II and hybridization to 32P-labeled alpha-globin gene probe. Seven among the 60 (11.7%) Samoans had triplicated alpha-globin loci type 1, while none had alpha thal2. On digestion with Bgl II the third alpha-globin gene was found in an additional 3.7 kb fragment in all seven Samoans with triplicated alpha-globin loci, while digestion with Bam HI produced an abnormal elongated 18.2 kb fragment carrying alpha-globin genes in addition to the normal 14.5 kb fragment. None of the Polynesian Samoans had alpha thal2 or alpha thal1. Only two of the Malaysians had triplicated alpha-globin loci.

Fulltext Body image differences among Malay, Samoan, and Australian women

McDowell AJ, Bond M

Asia Pac J Clin Nutr, 2006;15(2):201-7.
PMID: 16672204

Comparisons of body attitudes and associated behaviours were undertaken using Malay, Samoan, and Australian female students. The general goal of the research was to determine the degree to which the observed pattern of attitudes and behaviours was attributable to culture. The specific analyses comprised an examination of group differences using standard measures that included the Body Attitudes Questionnaire, the Three-Factor Eating Questionnaire and detailed questions concerning the use of diet and exercise as weight control strategies. The main findings concerned a number of cultural differences, particularly in relation to diet and exercise, that were evident even with the effect of body mass index held constant. These results are interpreted in terms of the efficacy of entrenched cultural beliefs in protecting against introduced, more dominant, cultural values. The Australian sample exhibited the most negative body image, although there was some evidence that Malays and Samoans were influenced by Western ideals of weight and shape. It is proposed that to fully understand the differential meaning of negative body image across cultures and the potential impact of westernisation, both within-group and between-group differences in body size need to be acknowledged.

Fulltext Association between the spread of COVID-19 and weather-climatic parameters

Carta MG, Scano A, Lindert J, Bonanno S, Rinaldi L, Fais S, et al.

Eur Rev Med Pharmacol Sci, 2020 08;24(15):8226-8231.
PMID: 32767354 DOI: 10.26355/eurrev_202008_22512

OBJECTIVE: To explore whether the climate has played a role in the COVID-19 outbreak, we compared virus lethality in countries closer to the Equator with others. Lethality in European territories and in territories of some nations with a non-temperate climate was also compared.
MATERIALS AND METHODS: Lethality was calculated as the rate of deaths in a determinate moment from the outbreak of the pandemic out of the total of identified positives for COVID-19 in a given area/nation, based on the COVID-John Hopkins University website. Lethality of countries located within the 5th parallels North/South on 6 April and 6 May 2020, was compared with that of all the other countries. Lethality in the European areas of The Netherlands, France and the United Kingdom was also compared to the territories of the same nations in areas with a non-temperate climate.
RESULTS: A lower lethality rate of COVID-19 was found in Equatorial countries both on April 6 (OR=0.72 CI 95% 0.66-0.80) and on May 6 (OR=0.48, CI 95% 0.47-0.51), with a strengthening over time of the protective effect. A trend of higher risk in European vs. non-temperate areas was found on April 6, but a clear difference was evident one month later: France (OR=0.13, CI 95% 0.10-0.18), The Netherlands (OR=0.5, CI 95% 0.3-0.9) and the UK (OR=0.2, CI 95% 0.01-0.51). This result does not seem to be totally related to the differences in age distribution of different sites.
CONCLUSIONS: The study does not seem to exclude that the lethality of COVID-19 may be climate sensitive. Future studies will have to confirm these clues, due to potential confounding factors, such as pollution, population age, and exposure to malaria.
