Quantifying the electric service panel capacities of California's residential buildings

This study seeks to quantify the size distribution of existing installed electrical service panels within California's residential buildings, a potentially significant barrier to future decarbonization efforts. A large sample of historical building permit data was collected for municipalities throughout the state, from which permitted panel upgrades were extracted and analyzed. These data were used to develop a method for estimating panel capacities that incorporates information about historical code requirements for panel sizing in new construction with a statewide database of parcel-level building attributes. Overall, we find that 3% of single-family (SF) and 10% of multi-family (MF) properties in California have panels in the smallest size range, which will most likely require upgrades. However, 32% of SF and 59% of MF properties have panels of intermediate size, which will likely require the addition of load management systems to support comprehensive electrification. Future panel upgrade needs are expected to be more acute within disadvantaged communities, where the proportion of SF homes with the smallest-sized panels is 4x that in more affluent neighborhoods. We discuss the implications of these and other results within the context of existing and planned future state policies related to residential electrification.

Prominin 1 and Tweety Homology 1 both induce extracellular vesicle formation.

Prominin-1 (Prom1) is a five-transmembrane-pass integral membrane protein that associates with curved regions of the plasma membrane. Prom1 interacts with membrane cholesterol and actively remodels the plasma membrane. Membrane bending activity is particularly evident in photoreceptors, where Prom1 loss-of-function mutations cause failure of outer segment homeostasis, leading to cone-rod retinal dystrophy (CRRD). The Tweety Homology (Ttyh) protein family has been proposed to be homologous to Prominin, but it is not known whether Ttyh proteins have an analogous membrane-bending function. Here, we characterize the membrane-bending activity of human Prom1 and Ttyh1 in native bilayer membranes. We find that Prom1 and Ttyh1 both induce formation of extracellular vesicles (EVs) in cultured mammalian cells and that the EVs produced are physically similar. Ttyh1 is more abundant in EV membranes than Prom1 and produces EVs with membranes that are more tubulated than Prom1 EVs. We further show that Prom1 interacts more stably with membrane cholesterol than Ttyh1 and that this may contribute to membrane bending inhibition in Prom1 EVs. Intriguingly, a loss-of-function mutation in Prom1 associated with CRRD induces particularly stable cholesterol binding. These experiments provide mechanistic insight into Prominin function in CRRD and suggest that Prom and Ttyh belong to a single family of functionally related membrane-bending, EV-generating proteins.

Alkaloid chemistry in pill-millipedes: Defensive secretion in two species of Typhloglomeris Verhoeff, 1898 (Diplopoda, Glomerida, Glomeridellidae)

AbstractMillipedes of the order Glomerida are known to produce quinazolinone alkaloids as defensive substances. However, chemical data are rather scarce and all hitherto available publications refer to a single glomeridan family, the Glomeridae. To contribute to the knowledge of the chemical ecology of glomeridans, we collected species, Typhloglomeris coeca Verhoeff, 1898 and T. varunae Makarov, Lučić, Tomić & Karaman, 2003, from a second family – Glomeridellidae. The defensive exudates were extracted in methylene chloride and analyzed by gas chromatography-mass spectrometry. Our results show that the secretions of the two glomeridellids contain the quinazolinone alkaloid homoglomerin (2-ethyl-1-methylquinazolin-4(1H)-one) as the sole defensive constituent. This report provides initial data on the chemoprofiles of members of the family Glomeridellidae and supports the phenomenon of chemical homogeneity of glomeridan defensive secretions. So far, all analyzed representatives of the order possess glomerin and/or homoglomerin as defensive equipment. The phylogenetic origin of alkaloidal compounds in the secretions of millipedes in general, and particularly the origin of quinazolinone alkaloids in Glomerida is discussed. Considering that the quinazolinone alkaloid defensive secretions may be the same (or very similar) in other Glomerida, our results have important implication for further studies of defensive secretions in these arthropods. Also, as data are available only for a limited number of glomeridan and colobognathan species, additional analyses are necessary to elucidate the evolution of alkaloid defensive secretion in Diplopoda.

Bi-layer deep feature fusion based mineral classification using hand-specimen images

Mineral classification is a crucial task for geologists. Minerals are identified by their characteristics. In the field, geologists can identify minerals by examining lustre, color, streak, hardness, crystal habit, cleavage, fracture, and specific features. Geologists sometimes use a magnifying hand lens to identify minerals in the field. Surface color can assist in identifying minerals. However, it varies widely, even within a single mineral family. Some minerals predominantly show a single color. So, identifying minerals is possible considering surface color and texture. But, again, a limited database of minerals is available with large-scale images. So, the challenges arise to identify the minerals using their images with limited images. With the advancement of machine learning, the deep learning approach with bi-layer feature fusion enhances the dimension of the feature vector with the possibility of high accuracy. Here, an experimental analysis is reported with three possibilities of bi-layer feature fusion of three CNN models like Alexnet, VGG16 & VGG19, and a framework is suggested. Alexnet delivers the highest performance with the bi-layer fusion of fc6 and fc7. The achieved accuracy is 84.23%, sensitivity 84.23%, specificity 97.37%, precision 84.7%, FPR 2.63%, F1 Score 84.17%, MCC 81.75%, and Kappa 53.59%.

Rare Missense Variants in KCNJ10 Are Associated with Paroxysmal Kinesigenic Dyskinesia.

Although the group of paroxysmal kinesigenic dyskinesia (PKD) genes is expanding, the molecular cause remains elusive in more than 50% of cases. The aim is to identify the missing genetic causes of PKD. Phenotypic characterization, whole exome sequencing and association test were performed among 53 PKD cases. We identified four causative variants in KCNJ10, already associated with EAST syndrome (epilepsy, cerebellar ataxia, sensorineural hearing impairment and renal tubulopathy). Homozygous p.(Ile209Thr) variant was found in two brothers from a single autosomal recessive PKD family, whereas heterozygous p.(Cys294Tyr) and p.(Thr178Ile) variants were found in six patients from two autosomal dominant PKD families. Heterozygous p.(Arg180His) variant was identified in one additional sporadic PKD case. Compared to the Genome Aggregation Database v2.1.1, our PKD cohort was significantly enriched in both rare heterozygous (odds ratio, 21.6; P = 9.7 × 10-8) and rare homozygous (odds ratio, 2047; P = 1.65 × 10-6) missense variants in KCNJ10. We demonstrated that both rare monoallelic and biallelic missense variants in KCNJ10 are associated with PKD. © 2024 The Authors.

DNA Barcoding of Invasive Terrestrial Plant Species in India.

Invasive plants are known to cause biodiversity loss and pose a major risk to human health and environment. Identification of invasive plants and distinguishing them from native species has been relied on morphological examination. Stringent requirement of floral characters and decreasing number of expert taxonomists are making conventional morphology-based identification system tedious and resource-intensive. DNA barcoding may help in quick identification of invasive species if distinct sequence divergence pattern at various taxonomic levels is observed. The present work evaluates the utility of four molecular markers; rbcL, matK, their combination (rbcL + matK), and psbA-trnH for identification of 37 invasive plant species from India and also in distinguishing them from 97 native species. A psbA-trnH locus was found to be of restricted utility in this work as it was represented by the members of a single family. A hierarchical increase in K2P mean divergence across different taxonomic levels was found to be the maximum for matK alone followed by rbcL + matK and rbcL alone, respectively. NJ clustering analysis, however, confirmed the suitability of combined locus (rbcL + matK) over individual rbcL and matK as the DNA barcode. RbcL showed the lowest resolution power among the three markers studied. MatK exhibited much better performance compared to rbcL alone in identifying most of the species accurately although it failed to show monophyly of genus Dinebra. Two families; Asteraceae and Poaceae, remained polyphyletic in the trees constructed by all three markers. Combined locus (rbcL + matK) was found to be the most suitable marker as it raised the resolution power of both the markers and could identify more than 90% of genera correctly. Phylogenetic tree constructed by Maximum-Parsimony method using combined locus as a molecular marker exhibited the best resolution, thus, supporting the significance of two-locus combination of rbcL + matK for barcoding invasive plant species from India. Present study contributes to the global barcode data of invasive plant species by adding fifty-one new sequences to it. Effective barcoding of additional number of native as well as invasive plant species from India is possible using this dual locus if it is combined with one or more new molecular plastid markers. Expansion of barcode database with a focus on barcode performance optimisation to improve discrimination ability at species level can be undertaken in future.

Unraveling the diversity of Trypanosoma species from Central Mexico: molecular confirmation on the presence of Trypanosoma dionisii and novel Neobat linages

Bats are one of the groups of mammals with the highest number of associated Trypanosoma taxa. There are 50 Trypanosoma species and genotypes infecting more than 75 species of bats across five continents. However, in Mexico, the inventory of species of the genus Trypanosoma associated with bats is limited to only two species (Trypanosoma vespertilionis and Trypanosoma cruzi) even though 140 species of bats inhabit this country. Specifically, 91 bat species have been recorded in the state of Veracruz, but records of trypanosomatids associated with this mammalian group are absent. Due to the complex Trypanosoma–bat relationship, the high diversity of bat species in Veracruz, as well as the lack of records of trypanosomatids associated with bats for this state, the aim of this work was to analyze the diversity of species of the genus Trypanosoma and their presence from a bat community in the central area of the state of Veracruz, Mexico. During the period of January to August 2022 in the Tequecholapa Environmental Management Unit where bats were collected using mist nets and blood samples were obtained from their thumbs. We extracted genetic material and amplified a fragment of 800 bp of the 18S ribosomal gene of the genus Trypanosoma by conventional PCR. The positive amplicons were sequenced, and phylogenetic reconstruction was performed to identify the parasite species. A total of 285 bats (149♀, 136♂) belonging to 13 species from 10 genera and a single family (Phyllostomidae) were collected. Twenty-three specimens from six species tested positive for the presence of Trypanosoma dionisii, Trypanosoma sp. Neobat 4, and a potential novelty species provisionally named as Trypanosoma sp. Neobat 6. The results of the present work increase the number of species of the genus Trypanosoma infecting bats in Mexico and in the Neotropical region.

Associations of Mental Health Service Utilization and Mental Health Diagnosis with Placement Instability Among Foster Children in a Southeastern State

AbstractPlacement instability for children in foster care is high, with children experiencing nearly 4.5 placement moves per 1,000 days in care on average. While prior research has demonstrated a predictive relationship between mental health problems and placement instability, few studies have examined the associations of specific mental health diagnoses or utilization of mental health (MH) services. To this end, this study seeks to investigate associations between MH service utilization, mental health diagnosis, and placement instability (rate of placement moves) for foster children. We analyzed statewide integrated administrative data to examine MH service utilization and mental health diagnosis on placement instability among foster children. We used SAS 9.4 to conduct descriptive, bivariate, and multiple linear regression models to address the objectives of the study. The retrospective cohort was composed of 1,002 children in foster care. The multivariable linear regression reveals that receiving in-patient services, receiving out-patient services, being diagnosed with conduct disorder, being Black children, older children, and female children, being placed in intensive case management, being sexually abused, having a single household family structure at time of removal, and having a high number of intakes significantly increased the rate of placement moves. The findings of this study have significant implications for the provision of mental health services to foster children and the promotion of placement stability, highlighting the role of child welfare professionals in fostering protective factors and mitigating risk factors to promote placement stability. Implications for practice and policy improvement are discussed.

Overexpressed yeast Bax inhibitor (Bxi1p/Ybh3p) is a calcium channel in E. coli

Human Bax Inhibitor-1 (HsBI-1/TMBIM6) is the founding member of the evolutionary conserved TMBIM superfamily of proteins that share sequence homology within the transmembrane Bax inhibitor-containing motif (TMBIM). Mechanistically, BI-1/TMBIM6 and all the other mammalian TMBIM proteins appear to be involved in the maintenance of calcium homeostasis, and the crystal structure of a bacterial TMBIM protein, BsYetJ, suggests that the protein is a pH-sensitive calcium leak. The budding yeast, Saccharomyces cerevisiae, has a single TMBIM family member (YNL305C) named Bxi1p/Ybh3p. To determine the function Bxi1p/Ybh3p, we overexpressed Bxi1p-GFP in E. coli to interrogate its putative calcium channel function. We show that bacterial cells expressing Bxi1p-GFP are more permeable to calcium than controls. Our data suggests that yeast Bax inhibitor (Bxi1p) is a calcium channel in E. coli, lending support to our proposal that Bxi1p is a bona fide member of the TMBIM family of proteins. Finally, parallel experiments also revealed that the human Bax Inhibitor-1 (HsBI1/TMBIM6) is also a calcium channel in bacteria.

Whose benefactors? Whose beneficiaries?—Negotiating help at the intersection between the family and the state

AbstractSocial work is characterized as a helping profession. Consequently, the nature and purposes of social work revolve around concepts of help and helping. In this article, I explore what happens when the extended family network and friends are brought together by child welfare services to make decisions to help a child. Based on analyses of a single videotaped family group conference, this article offers insights into the challenges and complexities families face when dealing with the mandated task to devise a plan that meets the child's needs. By examining sequences of interaction where friends and family members discuss future scenarios with some cast as beneficiaries and others as benefactors, I show how some of these complexities can be captured in terms of the relationship between benefactive stance and benefactive status. The complexities include ambiguities regarding the relationship between nominated future scenarios and the problem(s) they were designed to solve. Furthermore, participants dealt with uncertainties regarding who was more inclined towards specific future scenarios and thus understood to be the actual beneficiary. Additionally, the analysis shows that social identities ascribed to recipients when resolutions to problems were linked to family members' past shortcomings complicated the acknowledgement and acceptance of assistance.

Refined linearly anisotropic couple-stress elasticity

A recently developed, refined version of the conventional linear couple-stress theory of isotropic elasticity is extended to include the influence of anisotropic material effects. With this development, the implied refined theory (1) retains ability to determine the spherical part of the couple-stress and (2) is further furnished with constitutive ability to embrace modelling of linearly elastic solids that exhibit inherent polar material anisotropy of advanced levels that reach the class of locally monoclinic materials. This type of anisotropy embraces most of the structural material subclasses met in practice, such as those of general and special orthotropy, as well as the subclass of transverse isotropy. The thus obtained, enhanced version of the refined theory is furnished with ability to also handle structural analysis problems of polar fibrous composites reinforced by families of perfectly flexible fibres or, more generally, polar anisotropic solids possessing one or more material preference directions that do not possess bending resistance. A relevant example application considers and studies in detail the subclass of polar transverse isotropy caused by the presence of a single family of perfectly flexible fibres. By developing the relevant constitutive equation, and explicitly presenting it in a suitable matrix rather than indicial notation form, that application also exemplifies the way that the spherical part of the couple-stress is determined when the fibres are straight. It further enables this communication to initiate a discussion of further important issues stemming from (1) the positive definiteness of the full, polar form of the relevant strain energy function and (2) the lack of ellipticity of the final form attained by the governing differential equations.

Craft breweries and residential property values

AbstractThis paper studies the effect of craft breweries on residential property values. Using a hedonic Difference‐in‐Differences (DID) approach and about 250 thousand housing transactions in Denver, Colorado from 1990 to 2016, we investigate the impact of proximity to a craft brewery on residential property values. We consider three types of residence (single‐family home, row house, and condominiums), three types of brewery (all craft breweries, microbreweries, and brewpubs/taprooms), and two measurements of distance (Euclidian and walk‐time). Our most robust results are found for single‐family homes, whose values enjoy a premium of up to 20.4% for being in proximity to a brewpub/taproom several years after, with the average annual maximum premium around 3%. As expected, premiums decline as distance from breweries increase. Beyond a distance of 0.5 km or a 10‐min walk‐time, the premium for a regional/microbrewery is greater than that for a brewpub/taproom. For single family homes within 4 km or 40‐min walk‐time, the annualized premium ranges between 0.41% and 3.01%. These findings support the narrative that craft breweries are a neighborhood asset.

Possibilities of Using the National Electronic Data Syetstem in Assessing the Control of Arterial Hypertension at The Primary Health Care Level in the Kyrgyz Republic Using the Example of a Single Family Medicine Center.

To determine the capabilities of the National Electronic System for collecting quantitative data necessary to assess the quality of management and effectiveness of arterial hypertension (AH) control at the primary health care (PHC) level and to develop indicators and possibilities of their use for a standardized report on the quality of AH management and control at the PHC level in the Kyrgyz Republic. Data from electronic outpatient records were processed for all registered patients of a pilot family medicine center (FMC) that was selected randomly. The registered patient group consisted of 91,226 people older than 18 years, including 37,740 men and 53,486 women. The data obtained during contact with a patient was entered by the family doctor into the electronic outpatient record and automatically forwarded to the center that collected and aggregated the data. To monitor AH control, 11 indicators were developed and evaluated. The indicators were divided into 3 groups: indicators for identifying AH, indicators for the quality of AH patient management, and indicators for the effectiveness of AH control. In total, 26,206 patients (7,933 men and 18,273 women) visited the FMC during a year, and blood pressure (BP) was measured in 71.4% of them. In 2022, 5,072 patients (5.6% of the registered group) visited the FMC for AH, including 1,539 men and 3,533 women (4.1 and 6.6% of the registered patient group, respectively; p<0.001). The proportion of patients with AH who, according to the clinical protocol, had their BP measured 2 times a year or more, was 81.4% and was slightly higher for women than for men (82.3% and 79.1%, respectively; p<0.01). 38.7% of AH patients received antihypertensive drugs. Lipid-lowering therapy was prescribed to 23.5% of AH patients. The proportion of AH patients taking acetylsalicylic acid was higher, 36.3% for the whole group, including 34.1% for men and 37.2% for women (p<0.05). The efficacy of AH treatment was 62.8%. Any monitoring system has limitations for the amount of useful data that can be obtained ensuring their proper quality. Taking this into account, two major indicators are suggested to use for evaluating the effectiveness of AH control at the PHC level: 1) the number of AH patients who have achieved the BP goal; 2) the number of AH patients who visited a medical institution (health care facility) during a calendar year relative to the number of registered patients (AH detectability).

Landscape of Constitutional SOX4 Variation in Human Disorders.

SOX proteins are transcription factors which play a role in regulating the development of progenitor cells and tissue differentiation. Twenty members are known, clustered in eight groups named A through H and sharing a common DNA-binding domain called the HMG (high-mobility-group) box. Eleven of the SOX genes have been associated with genetic disorders so far, covering a broad spectrum of developmental diseases. SOX4 is a single-exon gene and belongs to the SOXC group, together with SOX11 and SOX12. SOX4 variants have been recently described to cause a highly penetrant but heterogeneous disorder, with a phenotypic spectrum ranging from mild developmental delays and learning difficulties to intellectual disabilities with congenital anomalies. Nineteen pathogenic variants have been reported to date, generally de novo, heterozygous, and inactivating, either stop-gain or missense, the latter ones primarily targeting the HMG domain. Further, a bi-allelic variant was reported in a single consanguineous family. Copy number variants leading to whole gene deletion or duplication are rare and not clearly associated with any neurodevelopmental disorder. Many open questions remain regarding the definition of variants of unknown significance, a possible role of missense variants outside the HMG domain, genotype-phenotype correlation, the range of phenotypic spectrum and modifying factors, and treatment options.

Food insecurity in children and young people in Scotland.

The aim of this review is to highlight the key issues in relation to food insecurity among children and young people living in Scotland. It provides an overview of the current context of food insecurity more generally within the UK and specifically in Scotland. Food insecurity has risen in Scotland evidenced through responses to national surveys and the dramatic increase in households relying on emergency food provision. Food insecurity is highest among young people, single parent families and single men. The key drivers of food insecurity include insufficient income, welfare reform, food inflation and geo-political events. Evidence suggests that food insecurity is negatively related to sufficient nutritional intake, and the implications for physical and mental health are profound. Policy actions implemented to mitigate the impact of food insecurity on children and young people include the introduction of the Scottish Child Payment, food voucher schemes, free school meals, and holiday food provision. Further evidence is required to evaluate the success of these policies in reducing or mitigating food insecurity. The review concludes by considering the ways in which a rights-based approach to food might benefit children and young people living in Scotland, and argues that wider systemic change is required.

Corporate investors and the housing affordability crisis: Having wall street as your landlord

AbstractGiven the importance of housing affordability to one's social class standing, one's ability to afford decent, secure housing is not only important on an individual level, but impacts intergenerational im/mobility as well. The purpose of this research is threefold. First, it examines the recent trend in bulk housing purchases by corporate investors who turn those purchases into single family rental properties. In so doing, it discusses the implications for the population in general, but for marginalized population in perticular, that is, persons of color and those inthe lower socioeconomic strata of society. Second, this research examines a closely related housing phenomenon, condominium deconversion, where corporate investors purchase privately owned condominiums in bulk who turn them into rental units. Third, summary analysis and suggestions for future research as well as legislative and policy proposals to offset housing affordability conclude this research.

Effect of a Financial Education and Coaching Program for Low-Income, Single Mother Households on Child Health Outcomes.

The financial difficulties of parents have a negative impact on the health of their children. This problem is more pronounced in single mother families. There is limited research on low-income, single mothers and how interventions to help them address financial difficulties may also benefit their children. The purpose of this study was to evaluate the effect of a year-long financial education and coaching program on school absenteeism and health care utilization of children in employed, low-income, single mother households. This was a post hoc analysis of the Finances First study, a randomized controlled trial conducted in 2017-2020 examining the impact of a financial coaching and education program on economic stability and health outcomes in 345 low-income, single mothers. Either generalized estimating equations (GEEs) or generalized linear mixed models (GLMMs) were used to account for relationships between participants. For the continuous outcomes of child absenteeism, physician visits, emergency room visits, and hospitalization days, a linear mixed-effects model was used. The Finances First study demonstrated improvements in various financial strain measures. Compared to the control group, children of intervention group participants experienced 1 fewer day of school absence (p = 0.049) and 1 fewer physician visit (p = 0.032) per year, but no impact was seen on emergency room visits (p = 0.55) or hospitalizations (p = 0.92). Addressing social determinants of health in parents is necessary for improving child health outcomes.

Research on the impact of the socio-educational environment on the academic performance of college students: the mediating role of study motivation.

Enhancing the academic performance (AP) of college students can contribute to the overall scientific literacy among this population, thereby fostering societal progress. The study investigates the correlation between college students' AP and the socio-educational environment (SEE, including family, roommates, and teachers), study motivation (SM, including self-efficacy and study behaviors). Based on the research findings, recommendations are offered to students, educators, and school administrators. Utilizing a stratified sampling approach, data was collected by selecting a sample of 330 first-year computer science students from a specific local university in Hebei Province, China. Data will be collected through a hierarchical sampling method. Using correlation analysis, difference analysis, and structural equation modeling (SEM) as data analysis methods. The data passed reliability and validity analysis (Cronbach's Alpha = 0.88, KMO = 0.88, χ2/df = 1.49RMSEA = 0.04). The independent sample T-test results showed that female students had higher academic performance than male students (p < 0.001), and there was no significant difference in academic performance between students from single parent or orphan families and students from normal families (p = 0.14), from non urban areas and from urban areas (p = 0.67). The results of the mediating effect analysis indicate that SM exerts complete mediation in the association between SEE and AP, with a mediating effect value of 0.18. The educational disparity between urban and rural areas in China is gradually narrowing. Support policies for students from impoverished families in higher education institutions are showing initial effectiveness. The conducive learning environment and educational atmosphere for students can indirectly influence their psychological state, thus impacting their academic performance during their university years.

Genome-wide polygenic risk scores for colorectal cancer have implications for risk-based screening.

Hereditary factors, including single genetic variants and family history, can be used for targeting colorectal cancer (CRC) screening, but limited data exist on the impact of polygenic risk scores (PRS) on risk-based CRC screening. Using longitudinal health and genomics data on 453,733 Finnish individuals including 8801 CRC cases, we estimated the impact of a genome-wide CRC PRS on CRC screening initiation age through population-calibrated incidence estimation over the life course in men and women. Compared to the cumulative incidence of CRC at age 60 in Finland (the current age for starting screening in Finland), a comparable cumulative incidence was reached 5 and 11 years earlier in persons with high PRS (80-99% and >99%, respectively), while those with a low PRS (< 20%) reached comparable incidence 7 years later. The PRS was associated with increased risk of post-colonoscopy CRC after negative colonoscopy (hazard ratio 1.76 per PRS SD, 95% CI 1.54-2.01). Moreover, the PRS predicted colorectal adenoma incidence and improved incident CRC risk prediction over non-genetic risk factors. Our findings demonstrate that a CRC PRS can be used for risk stratification of CRC, with further research needed to optimally integrate the PRS into risk-based screening.

Distribution and diversity of aquatic insects in different water bodies of Qatar.

Aquatic insect fauna remains an important tool for bio indication of environmental disturbance, while maintaining a healthy aquatic system. The purpose of the study was to document and to identify the diversity and distribution patterns of aquatic insect, a highly ignored aspect from the Qatar. Following the standard procedures, the samples were collected from aquatic habitats during the period October 2015 to May 2017 on monthly basis. A total of 11,287 individuals, belonging to 6 orders were captured. Dipterans were the abundant with the percentages of 71.01 (n=8,015), while the lowest percentage was observed for Coleoptera 0.04 (n=05). Twelve insects families were identified, among these five were reported under Diptera, followed by Hemiptera (03), while Coleoptera, Tricoptera, Odonata, and Ephemeroptera were represented by single families. Among the selected localities, Dipterans were collected from 10 stations, followed by Hemiptera (9), Coleoptera (4), Odonota (4), Ephemeroptera (3) and Trichoptera (1) respectively. Among the water bodies samples, streams were the most preferred habitats (n=2,767), while drinking water pools were the least (27). Moreover, the highest Simpson diversity index of 1.48 and lowest of 0.47 was recorded for flooded sewage pool and plastic containers respectively, while the low evenness values were observed for ponds, and less than 1 Margalef's diversity values were seen for all habitats. This study documents the patterns of the diversity and distribution of aquatic insects, and provides a baseline for the future studies from Qatar.
