Morphometric analysis, feeding capacity and proteobacteria wolbachia screening in yellow-assassin bug Cosmolestes picticeps

The yellow-assassin bug, Cosmolestes picticeps (Hemiptera: Reduviidae) is a generalist predator that has potential use as biological control agent in oil palm agroecosystem. They are known to feed on insect pests like bagworm. To facilitate understanding on the suitability of C. picticeps as an alternative means to manage oil palm pests, and little impact on beneficial insects, this study investigated the morphological variations, feeding capacity and proteobacteria in C. picticeps. To examine the relationships between morphology and feeding capacity of C. picticeps, a total of 90 male and 90 female individuals of C. picticeps collected were measured, and then provided with weevil individuals in captivity. The results showed no significant correlation between the size of C. picticeps with the number of weevil individuals consumed. Meanwhile, the present study also want to determine whether there are proteobacteria Wolbachia sp. in female C. picticeps gut content using Polymerase Chain Reaction (PCR) amplification. The result showed absent of Wolbachia surface protein and Wolbachia citrate synthase coding gene amplification. Based on the present study, more information on the C. picticeps should be assessed as they have the potential as biological control agent to suppress insect pests in agricultural ecosystem

Impact assessment of Sea Level Rise (SLR) on coastal erosion through multiple-criteria index in Pantai Remis, Perak

Extreme climate changes have led to natural disasters, especially sea level rise, which leads to coastal erosion and can affect the safety and economy of the local community. Through an index of different criteria, this study aims to find out how sea level rise affects erosion along the coast in Pantai Remis, Perak. A spatial model for determining the impact of sea level rise on coastal erosion was designed, as was a risk assessment framework for the impact of sea level rise on coastal erosion using the multi-criteria index method. This study focuses on the geomorphology, coastal slope, coastal elevation, coastal buffers, tidal range, wind speed, building density, population activity, and road network. As a result of the calculation of indices and weights for the study, four out of 28 (14.3%) management units are in areas that received a very high impact of sea level rise on coastal erosion. Areas classified as very high are likely to be affected by the movement of small boats and cause the level of erosion in the area to worsen. Three out of 28 (10.7%) management units are classified as high, 13 (46.4%) are classified as moderate, and eight out of 28 (28.6%) management units are low. Overall, Pantai Remis, Perak, is a beach with a moderate impact of coastal erosion due to sea level rise. This approach allows for the incorporation of multiple factors and the prioritization of mitigation measures based on their relative importance, which can be useful for decision-making and resource allocation

A decade of amphibian studies (Animalia, Amphibia) at Sekayu lowland forest, Hulu Terengganu, Peninsular Malaysia

Amphibians of Sekayu lowland forest have been studied more than a decade, with discoveries of new records of species showing no sign of abating between the years 2003 to 2020, indicating the remarkably rich diversity of anurans in this forest. Despite ceaseless anthropogenic activities in this area, this study successfully recorded 52 species of amphibians from 32 genera in the lowland forest of Sekayu. The species composition consisted of a single species from the family Ichthyophiidae and 51 species of anurans of 31 genera and six families. The number of species recorded has steadily increased especially during more recent surveys from 2015 to 2020. This study augments the total number of amphibian species recorded from Hulu Terengganu by ten additional species, increasing the total to 70 species for the district

Characteristics and outcomes of an international cohort of 600 000 hospitalized patients with COVID-19

Background: We describe demographic features, treatments and clinical outcomes in the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) COVID-19 cohort, one of the world's largest international, standardized data sets concerning hospitalized patients. Methods: The data set analysed includes COVID-19 patients hospitalized between January 2020 and January 2022 in 52 countries. We investigated how symptoms on admission, co-morbidities, risk factors and treatments varied by age, sex and other characteristics. We used Cox regression models to investigate associations between demographics, symptoms, co-morbidities and other factors with risk of death, admission to an intensive care unit (ICU) and invasive mechanical ventilation (IMV). Results: Data were available for 689 572 patients with laboratory-confirmed (91.1%) or clinically diagnosed (8.9%) SARS-CoV-2 infection from 52 countries. Age [adjusted hazard ratio per 10 years 1.49 (95% CI 1.48, 1.49)] and male sex [1.23 (1.21, 1.24)] were associated with a higher risk of death. Rates of admission to an ICU and use of IMV increased with age up to age 60 years then dropped. Symptoms, co-morbidities and treatments varied by age and had varied associations with clinical outcomes. The case-fatality ratio varied by country partly due to differences in the clinical characteristics of recruited patients and was on average 21.5%. Conclusions: Age was the strongest determinant of risk of death, with a ∼30-fold difference between the oldest and youngest groups; each of the co-morbidities included was associated with up to an almost 2-fold increase in risk. Smoking and obesity were also associated with a higher risk of death. The size of our international database and the standardized data collection method make this study a comprehensive international description of COVID-19 clinical features. Our findings may inform strategies that involve prioritization of patients hospitalized with COVID-19 who have a higher risk of death
