Aboriginal and Queer Identity/ies in Western Australia: When there is a need to know in therapeutic settings
No full textA central question for the exploratory Aboriginal and LGBTQ+ researcher led project ‘Breaking the Silence: Being Indigenous and identifying LGBTQ+’ (Breaking the Silence) is how provision of genuinely inclusive service responses for Aboriginal and Torres Strait Islander people identifying as LGBTQ+ can be developed. This article presents the qualitative findings of this mixed-methods research project to show how organizational staff working in health, education and social support services in Western Australia consider the Aboriginal LGBTQ+ identity/experience. Analysis of the written, interview and focus group responses to a question about the relevance of LGBTQ+ identity show that these questions need to be considered and evaluated within diverse service cultures and philosophies of services. Staff views are diverse and organizational consensus on the relevance (or not) of LGBTQ+ identity needs to be the precursor before the development or consideration of changes to service delivery and models
Seed priming with boron and Bacillus sp. MN54 inoculation improves productivity and grain boron concentration of chickpea
No full textContext: The production of chickpea (Cicer arietinum L.) is negatively affected by boron (B) deficiency. In Pakistan, the crop grown under B deficiency produces grains with low B concentration. Application of B-tolerant bacteria (BTB) is a promising option to improve B supply to plants grown under B deficiency.
Aims: This study was focused on determining the appropriate concentration of B for seed priming, and its effects with BTB inoculation on growth, productivity and grain B concentration of chickpea.
Methods: Chickpea seeds were primed in aerated solutions of B concentrations in the range 0.01–0.5% (w/v), with hydroprimed and dry seeds as controls. Concentrations >0.1% proved toxic and seeds failed to germinate. Hence, B was further diluted to concentrations in the range 0.0001–0.1%. Pots containing chickpea seeds were divided into two sets having all B treatments. One set was inoculated with BTB (5 mL per pot of pure Bacillus sp. MN54 culture at 10 9 cfu mL−1); the other set was not inoculated.
Key results: Seed priming with B along with BTB inoculation improved stand establishment, growth, nodulation, yield and grain B concentration of chickpea. Seed priming treatments with B at 0.001% and 0.0001% along with BTB inoculation were most effective for improving stand establishment, seedling growth and grain yield, whereas 0.1% B was more effective for improving grain B concentration.
Conclusions: Seed priming with 0.001% B along with inoculation of Bacillus sp. MN54 improved seed germination, nodulation, yield and grain B concentration of chickpea under B-deficiency conditions.
Implications: Seed inoculation with BTB i.e., Bacillus sp. MN54 coupled with seed priming in 0.001% B solution is a viable option to improve yield and grain B concentration of chickpea grown on B-deficient soils
Non-detection of mycoviruses in amphibian chytrid fungus (Batrachochytrium dendrobatidis) from Australia
No full textMycoviruses may influence the pathogenicity of disease-causing fungi. Although mycoviruses have been found in some chytrid fungi, limited testing has not detected them in Batrachochytrium dendrobatidis (Bd), the cause of the devastating amphibian disease, chytridiomycosis. Here we conducted a survey for mycovirus presence in 38 Bd isolates from Australia (n = 31), Brazil (n = 5) and South Korea (n = 2) with a combination of modern high-throughput sequencing and conventional dsRNA cellulose chromatography. Mycoviruses were not detected in any isolates. This result was unexpected, given the long evolutionary history of Bd, as well as the high prevalence of mycoviruses in related fungal species. Given our widespread sampling in Australia and the limited number of Bd introductions, we suggest that mycoviruses are uncommon or absent from Australian Bd. Testing more isolates from regions where Bd originated, as well as regions with high diversity or low fungal virulence may identify mycoviruses that could aid in disease control
P is for persistence: Soil phosphorus remains elevated for more than a decade after old field restoration
No full textUnderstanding constraints to ecological restoration on former agricultural land has become increasingly important due to agricultural land degradation in the developed world, and growing evidence for enduring agricultural legacies that limit native species recovery. In particular, the removal of native plant biomass and subsequent disturbance of soil properties through farming activities can alter soil ecosystem processes. Planting of native plant species is a common approach to restoring native vegetation on agricultural land and is assumed to benefit soil ecosystem processes, but the degree to which altered soil chemical processes recover is poorly documented. We investigated recovery of soil chemical properties after restoration in semiarid Western Australia, hypothesizing that elevated nutrient concentrations would gradually decline post planting, but available phosphorus (P) concentrations would remain higher than reference conditions. We used a space-for-time substitution approach, comparing 10 planted old field plots with matched fallow cropland and reference woodlands. Sampling on planted old fields and reference woodland plots was stratified into open patches and under tree canopy to account for consistent differences between these areas. The most prominent legacy of cropping was significantly and substantially higher concentrations of soil available P in fallow croplands and restored old fields compared with reference woodlands. Soil mineral nitrogen (N) concentrations were elevated in fallow croplands compared to open patches in reference woodlands (ammonium and nitrate) and under the tree canopy (ammonium). However, in restored old fields, mineral N concentrations were similar to woodland sites, providing evidence for amelioration over time. No significant differences in nutrient concentrations under tree canopies compared with open patches had developed in the planted old fields, despite a distinction between open patches and he under ttree canopy in reference woodlands for total N. We conclude that soil P legacies in old fields may inhibit the recolonization of native species that are sensitive to, or uncompetitive at, elevated P concentrations. To achieve full recovery, further research is required to test restoration practices aimed at reducing soil P concentrations to facilitate native plant establishment and persistence
The impact of different weed management systems on weed flora and dry biomass production of barley grown under various barley-based cropping systems
Get PDFWeeds are among the major issues responsible for reduction in yield and profit in any crop production system. Herbicides are the easiest and quickest solution of weeds; however, their frequent use exert negative consequences on environment, human health, and results in the evolution of herbicide-resistant weed species. Due to these reasons, alternative weed management methods that are less harmful to environment and human health are needed. This two-year study evaluated the impact of different weed management options, i.e., false seedbed (FS), allelopathic water extracts (AWE), chemical control (CC), weed-free (WF) weedy-check (WC) on weed spectrum in various barley-based cropping systems, i.e., fallow-barley (FB), maize-barley (MB), cotton-barley (CB), mungbean-barley (M*B), and sorghum-barley (SB). Data relating to density, diversity, and biomass production of weed species prevailing in the studied cropping systems were recorded. Interactive effect of weed management methods and barley-based cropping systems significantly altered weed diversity, and densities of individual, broadleaved, and grassy weeds. A total 13 weed species (ten broadleaved and three grass) were recorded during both years of study. The highest dry biomass, diversity, and density of individual, broadleaved, and grassy weeds were noted in WC treatment, whereas WF treatment resulted in the lowest values of these traits. Chemical control resulted in the highest suppression of weed flora and improved dry biomass production of barley followed by AWE. The SB cropping system with CC or AWE resulted in the least weed flora. The M*B cropping system with CC or AWE produced the highest dry biomass of barley. It is concluded that including sorghum crop in rotation and applying AWE could suppress weeds comparable to herbicides. Similarly, including mungbean in rotation and applying AWE could increase dry biomass production of barley. In conclusion, herbicides can be replaced with an eco-friendly approach, i.e., allelopathy and inclusion of sorghum crop could be helpful in suppressing weed flora
Trainee therapist personality and the rating of cognitive behavioural and dynamic interpersonal therapy processes
No full textTherapist factors are generally thought to be important predictors of the capacity to understand and respond to clinical material. The current study aims to identify which features of personality and clinical symptomatology predict a trainee therapist's rating of cognitive behavioural (CB) and psychodynamic interpersonal (PI) processes in video recordings of these therapies. Eighty psychology trainees completed the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and watched two video recordings of therapy sessions showing prototypical examples of CB and PI psychotherapy, rating the processes they could identify using the Comparative Psychotherapy Process Scale (CPPS). Trainees accurately differentiated CB from PI process while viewing the CB session but rated the CB video higher in PI processes than the PI video itself. Bayesian regression models showed that the most consistent MMPI-2-RF scale that predicted variance in ratings was hypomanic activation (RC9) predicting higher ratings of all psychotherapy processes in both conditions, while clinical scale factors such as Aggressiveness-Revised (AGGR-r) and personality scale factors of Psychoticism-Revised (PSYC-r) and Negative Emotionality/Neuroticism-Revised (NEGE-r) showed some notable but less consistent predictions. The variances in psychotherapy process ratings accounted for by MMPI-2-RF scales ranged from 15% to 51%. The study suggests that some clinical symptoms and personality factors do influence the rating of psychotherapy processes by psychology trainees, but further studies would be required to substantiate such findings. These findings have relevance to therapist training and selection for clinical training and therapist mental health
Genetic mapping of tolerance to iron deficiency chlorosis in peanut (Arachis hypogaea L.)
No full textIron deficiency chlorosis (IDC) under calcareous and alkaline soils is a significant abiotic stress affecting the growth and yield of peanut. In this study, the genomic regions governing IDC tolerance were mapped using a recombinant inbred line (RIL) population derived from TMV 2 (susceptible to IDC) and TMV 2-NLM (tolerant to IDC), which was phenotyped during the rainy seasons of 2019 and 2020 in the iron-deficient calcareous plots. The best linear unbiased prediction (BLUP) values for IDC tolerance traits like visual chlorotic rating (VCR), and SPAD chlorophyll meter reading (SCMR) were used for QTL analysis along with a genetic map carrying 700 GBS-derived SNP, AhTE and SSR markers. In total, 11 and 12 main-effect QTLs were identified for VCR and SCMR, respectively. Among them three QTLs were major with the phenotypic variance explained (PVE) of 10.3–34.4% for VCR, and two QTL were major for SCMR with PVE of 11.5–11.7%. A region (159.3–178.3 cM) on chromosome Ah13 carrying two QTLs (one each for VCR and SCMR) was consistent with the previous report. A SNP marker, Ah14_138037990 identified from single marker analysis for VCR was located in the intronic region of the gene Arahy.QA0C1, which is important for protein-binding. Overall, this study identified new QTLs and also validated QTL for IDC tolerance. These genomic resources could be useful for genomics-assisted breeding of peanut for IDC tolerance
Responsible agriculture must adapt to the wetland character of mid‐latitude peatlands
Get PDFDrained, lowland agricultural peatlands are greenhouse gas (GHG) emission hotspots and a large but vulnerable store of irrecoverable carbon. They exhibit soil loss rates of ~2.0 cm yr−1 and are estimated to account for 32% of global cropland emissions while producing only 1.1% of crop kilocalories. Carbon dioxide emissions account for >80% of their terrestrial GHG emissions and are largely controlled by water table depth. Reducing drainage depths is, therefore, essential for responsible peatland management. Peatland restoration can substantially reduce emissions. However, this may conflict with societal needs to maintain productive use, to protect food security and livelihoods. Wetland agriculture strategies will, therefore, be required to adapt agriculture to the wetland character of peatlands, and balance GHG mitigation against productivity, where halting emissions is not immediately possible. Paludiculture may substantially reduce GHG emissions but will not always be viable in the current economic landscape. Reduced drainage intensity systems may deliver partial reductions in the rate of emissions, with smaller modifications to existing systems. These compromise systems may face fewer hurdles to adoption and minimize environmental harm until societal conditions favour strategies that can halt emissions. Wetland agriculture will face agronomic, socio-economic and water management challenges, and careful implementation will be required. Diversity of values and priorities among stakeholders creates the potential for conflict. Successful implementation will require participatory research approaches and co-creation of workable solutions. Policymakers, private sector funders and researchers have key roles to play but adoption risks would fall predominantly on land managers. Development of a robust wetland agriculture paradigm is essential to deliver resilient production systems and wider environmental benefits. The challenge of responsible use presents an opportunity to rethink peatland management and create thriving, innovative and green wetland landscapes for everyone's future benefit, while making a vital contribution to global climate change mitigation
Breastfeeding rates of Aboriginal and Torres Strait Islander women in Australia: A systematic review and narrative analysis
No full textBackground
Australian Aboriginal and Torres Strait Islander (referred to hereafter as Aboriginal) women breastfeed at lower rates than non-Aboriginal women, and rates vary across and within Aboriginal populations.
Aim
To determine rates of breastfeeding initiation and maintenance and compare individually collected survey data with existing routinely collected state and national breastfeeding data for Aboriginal women.
Methods
CINAHL, Medline, EMBASE, SCOPUS, PsycINFO, and the Cochrane library were searched for peer-reviewed literature published between 1995 and 2021. Quantitative studies written in English and reporting breastfeeding for Aboriginal women or women having an Aboriginal infant were included. Screening and quality assessment included co-screening 10% of papers. Two reviewers completed data extraction. A proportional meta-analysis was undertaken for breastfeeding initiation and narrative data synthesis used to summarise breastfeeding maintenance.
Findings
The initial search identified 12,091 records, with 31 full text studies retrieved, and 27 reports from 22 studies met inclusion criteria. Breastfeeding initiation was 78% (95% CI 0.71, 0.84), however, rates were lower than non-Aboriginal women. Maintenance ranged between one week and five years. Rates and definitions varied significantly between studies, with inconsistencies in government collection and reporting of breastfeeding.
Conclusion
Significant variation in definitions and reporting make comparisons difficult. Breastfeeding rates were below recommended targets. Future pattern and trend analyses require standardised measures and definitions. Current collection and reporting of breastfeeding data, particularly routinely collected state-based data, is inadequate to present an accurate picture of current breastfeeding in Australia for Aboriginal women and infants, and to effectively inform interventions and policies
Detection and distribution of virulence genes in Aeromonas hydrophila isolates causing infection in cultured carps
Get PDFAeromonas hydrophila is a bacterium associated with many diseases and disorders such as fin rot, skin ulcers and lethal hemorrhagic septicemia in fish. It bears several virulence factors including type III secretion system (T3SS), aerolysin, cytolytic enterotoxin and enzymes (e.g., hemolysins, lipase) that seem to play an important role in its pathogenesis. Detection of virulence markers by polymerase chain reaction (PCR) is a key procedure in defining the pathogenic ability of pathogenic bacteria and preparing a vaccine for its treatment. In this sense, this study was aimed to determine the frequency of virulence genes in isolates obtained from infected cultured carps in Khuzestan province. Out of 200 moribund carps with septicemic symptoms, 125 isolates were belonged to the motile aeromonads and 59 isolates were identified as A. hydrophila by biochemical methods. Finally, using PCR analysis, 31 isolates were identified as A. hydrophila. Five virulence genes were detected in these isolates including hemolysin, aerolysin, cytolytic enterotoxin and T3SS (aopB and ascV) by specific primers. Results showed that 23 (74.19%), 18 (58.06%), 16 (51.61%), 13 (41.63%) and 10 (32.25%) isolates possessed cytolytic enterotoxin, hemolysin, aerolysin, and T3SS genes, respectively. The results of the present study showed that among 31 isolates, only five isolates had all of dominant virulence genes. Thirteen other isolates had genotypes including hlyA+, aerA+, and act+. The remaining isolates had at least one virulence gene. This study showed that determination of the virulence genes by PCR can be a reliable method to identify a potential pathogenic Aeromonad strain
