To clarify the relationships of Pedesta submacula (Leech, 1890), P. submacula rubella (Devyatkin, 1996) and P. similissima (Devyatkin, 2002), specimens from various localities in China and Vietnam, including the type materials of P. submacula rubella and P. similissima were examined. A neighbor-joining (NJ) tree was also reconstructed based upon partial COI sequences of 24 ingroup specimens and 4 outgroup species. The result shows that P. similissima is a synonym of P. submacula, and P. submacula rubella belongs to a separate species. The mean Kimura-2-Parameter genetic distance between P. submacula and P. rubella stat. n. is 4.4%. Wing patterns and genitalic structures of these taxa are illustrated and compared. A distribution map of both species is provided.

A New Species

A new species of the genus Pedesta Hemming, 1934, viz. P. wangi sp. nov., is described as new to science from northwestern Guangxi, southern China. Based upon 455 bp partial COI sequences, a neighbor-joining (NJ) tree including the new species and twelve congeneric species is reconstructed. It shows that P. wangi sp. nov. is a cryptic species of P. xiaoqingae (Huang & Zhan, 2004), and the mean Kimura-2-Parameter distance between them reaches 2.8%. Wing patterns and genitalic structures of the males of the two species are illustrated and compared. In addition, three female samples are associated with P. xiaoqingae male in the NJ tree, and its wing pattern and genitalia are illustrated and described herein for the first time.

Abstract Given current and projected changes in the climate, the composition of mosquito species is predicted to shift geographically with implications for the transmission dynamics of vector-borne pathogens. Many mosquito species are rarely collected in Canada and their history is poorly understood; thus assessing their potential role as vectors for pathogenesis is difficult. Mosquitoes were collected from four trapping sites in Quebec Province, Canada, from June to September during 2018 and 2019 using BG sentinel traps. From all morphologically identified female mosquitoes, at least one specimen was selected for identification confirmation using the DNA-barcoding technique. Sequences were subjected to alignment and a Neighbor-Joining (NJ) tree was created using Geneious software. In total, 2,752 female mosquitoes belonging to 20 species over five genera: including Aedes (Ae.), Anopheles (An.), Culex (Cx.), Culiseta (Cu.), Coquillettidia (Cq.) were collected. The predominant mosquito was found to be Ae. cinereus. The highest number of mosquito species was captured in July, followed by August, September, and then June. Five genera were characterized by a distinctive set of cytochrome oxidase I (COI) sequences that formed well-supported clusters in the NJ-tree. The presence of Ae.japonicus in Quebec provides an initial look at the distribution of mosquito species in eastern Canada, which may put Canadians at risk of a wider range of arboviruses.

The family Myriangiaceae is relatively poorly known amongst the Dothideomycetes and includes genera which are saprobic, epiphytic and parasitic on the bark, leaves and branches of various plants. The family has not undergone any recent revision, however, molecular data has shown it to be a well-resolved family closely linked to Elsinoaceae in Myriangiales. Both morphological and molecular characters indicate that Elsinoaceae differs from Myriangiaceae. In Elsinoaceae, small numbers of asci form in locules in light coloured pseudostromata, which form typical scab-like blemishes on leaf or fruit surfaces. The coelomycetous, “Sphaceloma”-like asexual state of Elsinoaceae, form more frequently than the sexual state; conidiogenesis is phialidic and conidia are 1-celled and hyaline. In Myriangiaceae, locules with single asci are scattered in a superficial, coriaceous to sub-carbonaceous, black ascostromata and do not form scab-like blemishes. No asexual state is known. In this study, we revisit the family Myriangiaceae, and accept ten genera, providing descriptions and discussion on the generic types of Anhellia, Ascostratum, Butleria, Dictyocyclus, Diplotheca, Eurytheca, Hemimyriangium, Micularia, Myriangium and Zukaliopsis. The genera of Myriangiaceae are compared and contrasted. Myriangium duriaei is the type species of the family, while Diplotheca is similar and may possibly be congeneric. The placement of Anhellia in Myriangiaceae is supported by morphological and molecular data. Because of similarities with Myriangium, Ascostratum (A. insigne), Butleria (B. inaghatahani), Dictyocyclus (D. hydrangea), Eurytheca (E. trinitensis), Hemimyriangium (H. betulae), Micularia (M. merremiae) and Zukaliopsis (Z. amazonica) are placed in Myriangiaceae. Molecular sequence data from fresh collections is required to confirm the relationships and placement of the genera in this family.

The maximum yield of the school shark fishery in south-eastern Australian waters was 4.09 million lb in 1949. The catch has fluctuated since then about a declining trend to 3.18 million lb in 1956. In 1944, 7.3 hooks were required to catch a shark of mean weight 14.7 lb. In 1956 the number of hooks required was almost doubled: 13.6 hooks were needed to catch sharks of mean weight 13.7 lb; the catch per hook dropped from 2.01 to 0.99 lb. Whereas the catch per boat-month remained relatively stable at 4765 lb for 1944 and 4643 for 1956, the number of hooks used per boat-month increased from 2366 to 4668 hooks in 12 years. Throughout this period the mean weight of sharks in eastern Bass Strait remained fairly steady (11-13 lb) whereas there was a drop of 3 lb from a mean weight of 17-20 lb in the predominantly mature portion of the stock in western Bass Strait. Fishermen in South Australia have reported a comparable drop in the mean weight of sharks in their catches. During the period 1941-46 there was unrestricted inshore fishing of juveniles and pregnant females with a consequent severe drop in the inshore population. The subsequent decline in the annual total catch is believed to be due not only to a too intensive offshore fishery but also to the resultant reduced recruitment and depressed reproductive potential caused by the earlier destruction of juveniles and pregnant females. In the data presented in this paper there is evidence that the school shark fishery, which is operating on a single stock of sharks with a slow growth rate, a late sexual maturity, and a low fecundity, shows trends which are suggestive of depletion. Because similar trends in the soupfin shark fishery of California and in the dogfish fishery of British Columbia were followed by depletion, it has been inferred that regulations to protect the vulnerable phases of the life history of the school shark of Australia may be required. Measures for conservation are discussed.

SummaryThe aim of the study was to determine the status of SE in people with physical disabilities (PwPD) and compare SE scores between active and inactive individuals. The sample of PwPD (n = 186) was divided into two groups of those who are regularly participating in sport (active; n = 88) and those who are not participating in any sport in their leisure (inactive; n = 98). The Rosenberg Self-Esteem Scale (RSES) was used as a primary research method. 10-item scale measures global self-worth by measuring positive and negative feelings about the self. Higher scores (from 10 to 40 points) indicate higher SE. The Pearson chi-square test was used to determine the differences of 10 RSES items and total scores between active and inactive PwPD. We found that the mean score of RSES in PwPD was 28.83 points; active PwPD observed total score of RSES 30.01 points and group of inactive PwPD showed the lowest SE by achieving 27.76 points. Mean scores comparison of each RSES item between active and inactive PwPD revealed higher SE in the group of active PwPD. Significantly higher SE was presented by 4 from 10 RSES items and by total score in the group of active PwPD. The results of our study confirmed that actively living PwPD have significantly higher SE comparing those PwPD who are living sedentary life style.

Introduction: The intrarenal resistance index (RI) is a calculated parameter for the assessment of the status of the graft during the follow-up ultrasound of the transplanted kidney. Currently it is still unclear the predictive value of RI, also in function of the time. Materials and Methods: We retrospectively investigated the correlation between the RI and the graft survival (GS) and the overall survival (OS) after transplantation. We evaluated 268 patients transplanted between 2003 and 2011, the mean followup was 73 months (12-136). The RI was evaluated at 8 days, 6 months, 1 year and 3 years. The ROC analysis was used to calculate the predictive value of RI and the Kaplan Mayer curves was used to evaluated the OS and PS. Results: The ROC analysis, correlated to the GS, identified a value of RI equal to 0.75 as a cut-off. All patients was stratified according to the RI at 8 days (RI ≤ 0,75: 212 vs RI > 0.75: 56), at 6 months (RI ≤ 0.75: 237 vs RI > 0.75: 31), at 1 year (RI ≤ 0.75: 229 vs RI > 0.75: 39) and at 3 years (RI ≤ 0.75: 224 vs RI > 0.75: 44). The RI showed statistically significant differences between the two groups in favor of those who had an RI ≤ 0.75 only at 8 days and at 6 moths (p = 0.0078 and p = 0.02 to 8 days to 6 months) on the GS. On the contrary, we observed that the RI estimated at 1 year and 3 years has not correlated with the GS. The same RI cut-off was correlate with PS after transplantation. We observed that there are no correlations between the RI and OS. Conclusions: The RI proved to be a good prognostic factor on survival organ when it was evaluated in the first months of follow- up after transplantation. This parameter does not appear, however, correlate with OS of the transplanted subject.

This study aimed to map the status of mangrove forests over the coasts of Hai Ha District and Mong Cai City in Quang Ninh Province by using 2019 Landsat-8 imagery. It then developed the AGB estimation model of mangrove forests based on the AGB estimation-derived plots inventory and vegetation indices-derived from Landsat-8 data. As results, there were five land covers identified, including mangrove forests, other vegetation, wetlands, built-up, and water, with the overall accuracy assessments of 80.0% and Kappa coefficient of 0.74. The total extent of mangrove forests was estimated at 4291.2 ha. The best AGB estimation model that was selected to estimate the AGB and AGC of mangrove forests for the whole coasts of Hai Ha District and Mong Cai City is AGB= 30.38 + 911.95*SAVI (R2=0.924, PValue <0.001). The model validation assessment has confirmed that the selected AGB model can be applied to Hai Ha and Mong Cai coasts with the mean difference between AGB observed and AGB predicted at 16.0 %. This satisfactory AGB model also suggests a good potential for AGB and AGC mapping, which offer the carbon trading market in the study site. As the AGB model selected, the total AGB and AGC of mangrove forests were estimated at about 14,600,000 tons and 6,868,076 tons with a range of from 94.0 - 432.0 tons ha-1, from 44.2 - 203.02 tons ha-1, respectively. It also suggests that the newly-developed AGB model of mangrove forests can be used to estimate AGC stocks and carbon sequestration of mangrove forests for C-PFES in over the coasts of Hai Ha District and Mong Cai City, which is a very importantly financial source for mangrove forest managers, in particular for local mangrove protectors.

Background: Information on social characteristics in human immunodeficiency virus (HIV) infected Nigerian children is scarce. The association between social characteristics such as single parenthood, low socio-economic status, polygamy and lack of parental education on the outcome of paediatric HIV admissions has been under studied.Methods: Information was obtained from the case notes of HIV infected children between the year 2006 and 2012 at a Nigerian tertiary hospital. Details of the information extracted include socio-demographics, diagnoses and outcome of management. Data was analysed with the SPSS 18 software.Results: Fifty (1.73%) of the total 2897 paediatric admissions were due to HIV disease. The mean age of the children studied was 3.7±2.9years and the 50 children were made up by 27 boys and 23 girls, giving a male to female ratio of 1:0.9. The mean age of the mothers and fathers were 28.7 and 36.7 years respectively. Pneumonia, septicaemia and tuberculosis accounted for more than 60% of admissions. Five (10.0%) children were from the upper, 12 (24.0%) from the middle and 33 (766.0%) from the lower socioeconomic classes. Twenty-four parents (couples) were both sero-positive for HIV and 7 discordant. Nineteen (38.0%) could not be classified because the status of the father was unknown. Of the 7 sero-discordant parents, 3 sero-negative fathers neglected their families. Thirty-nine children were from monogamous homes, nine from polygamous and two were raised by single parents. There were two discharges against medical advice and eleven deaths. The average number of siblings of the children studied was 2.57±2.1. Mortalities on admission were significantly associated with, parental financial constraints and the admitted HIV infected child having more than one sibling (p<0.05).Conclusions: It was concluded that appropriate interventions to manage these associations will most likely improve the outcome of admissions. Strategies of improving disclosure and prevention of negative outcome of disclosures, such as family neglect in sero-discordant couples also need to be identified.
