In the dry regions environments such as Saudi Arabia, bacterial endophytes isolated from the roots and soil of healthy wild plants can promote plant growth by developing siderophores, phosphate solubilizing, Indole 3 Acetic Acid (IAA), and inhibit the growth of some plant fungal pathogens. This study aimed to isolate bacteria from wild plants in dry regions and to investigate their ability to be used as plant growth-promoting agent and inhibit plant pathogenic fungi. More than ninety endophytic bacterial isolates associated with the leaves, roots, and soil of healthy wild plants were collected from different sites in the Qassim region, Kingdom of Saudi Arabia, with the aim of characterizing and testing for their ability to promote plant growth activities and inhibit plant pathogenic fungi. Seventy strains were shown to produce indole-3-acetic acid (IAA) and 45 isolates produced siderophores, with 16 of these exhibiting large amounts. Twelve isolates tested positive for phosphate solubilization, with two isolates (QUSA 66 and QUSA 91) exhibiting greater efficiency for phosphate solubility. Twenty-five isolates produced more than 100 µg mL-1 of IAA, with production ranging from 100.5 to 404.7 µg mL-1. Six of these bacterial isolates (QUSA 2, 7, 10, 29, 30. and 40) produced more than 200 µg mL-1. A wide spectrum of activities was noted within the pseudomonas strains, indicating promising plant growth-promoting potential (e.g., the isolates from Pulicaria crispa and Calligonum comosum). In vitro results against plant pathogenic fungi showed that fifteen of the bacterial isolates inhibited growth of fungal mycelia by producing wide antagonistic zones. The isolates QUSA 26, 27, 28, 36, and 87 were able to produce siderophores and IAA and to solubilize phosphate. In addition, these isolates delayed mycelium growth of some Fusarium, Rhizoctonia solani, Botrytis, and Stemphylium spp

This study aims to determine the contribution of Adversity Quotient and perceptions on the teachers' teaching strategies and the parents' consent to the students' mathematics learning outcomes. This study utilises a quantitative research methodology implementing the ex-post facto research method as the independent variables are the events that have occurred. The population in this study was mathematics teachers and high school students in Buleleng Regency. A random sampling technique is used to determine the sample of the study. The data collection technique to measure (1) the contribution of Adversity Quotient and perceptions on the teachers' teaching strategies, and (2) the parent's consent are collected through validated and reliable questionnaires. Furthermore, the students' math results are obtained from their daily test results. The collected data were analyzed by using a path analysis technique. The findings conclude that there is a direct relationship between teacher’s teaching strategies and the students’ mathematics learning outcome by 52.9% and the parents’ consent to their children’s mathematics learning outcome by 23.3%. The difference of the total percentage in the findings is influenced by other factors which are not included in this study. All of these factors affect student learning outcomes either directly or indirectly.

Sexual violence is largely absent from studies on violence against women in disasters. The role of men in perpetrating violence against women is overlooked or excused and women are usually blamed in both countries. A review of 2 studies of men’s violence against women after floods and earthquakes in Iran and bushfires in Australia show remarkable similarities. Although cultural contexts and the way gender inequality is established and demonstrated are different, these studies reveal unexpected parallels. The context of disaster lays it bare. Participants of both studies were disaster-affected people in Iran and Australia who revealed the taboos that prevent women speaking of violence that is exacerbated in a disaster context. Men play important roles in preventing and responding to violence against women as the result of their responsibilities and positions at the household and community levels. The objective of this paper was to compare the findings from these studies and consider the difficulties faced in conducting studies related to the roles of men and women roles during and after disaster events.

A new short – horned lizard species of the genus Acanthosaura from southern Thailand, is described herein. The species was previously recognised as Acanthosaura crucigera and has been reported to present a wide distribution across mainland south-east Asia. The combination of modern morphological studies of Acanthosaura meridiona sp. nov. allows its separation from closely related species A. crucigera, on the basis of presenting more nuchal scales, more scales between diastema, more scales bordering rostral scales and more midline ventral scales. Mitochondrial DNA analysis also indicated a sister relationship between A. meridiona sp. nov. and A. crucigera with a 100 % probability according to Bayesian and maximum – likelihood analyses. The pairwise distance between A. meridiona sp. nov. and A. crucigera ranges from 9.9 – 11.1 %, while the distance between A. meridiona populations ranges from 0 – 0.9 %. This new discovery contributes to the redescription of the distribution of A. crucigera under Kra Isthmus and its replacement by A. meridiona sp. nov.

The poorly known northeastern water skink Tropidophorus assamensis is only known from the type locality (Harigaj Range, Sylhet District) in Bangladesh, and few localities in Assam and Mizoram States, north-eastern India. Little is known about the biology including the systematics of the species. In this study, we present for the first time, genetic data (16s rRNA) and inferred its phylogenetic position. In addition to this, we provide updated morphological data along with new distributional records of the species from Mizoram State of north-east India.

The impact of climate change on Malagasy amphibians remains poorly understood. Equally, deforestation, fragmentation, and lack of connectivity between forest patches may leave vulnerable species isolated in habitat that no longer suits their environmental or biological requirements. We assess the predicted impact of climate change by 2085 on the potential distribution of a Critically Endangered frog species, the golden mantella (Mantella aurantiaca), that is confined to a small area of the central rainforest of Madagascar. We identify potential population distributions and climatically stable areas. Results suggest a potential south-eastwardly shift away from the current range and a decrease in suitable habitat from 2110 km2 under current climate to between 112 km2 – 138 km2 by the year 2085 – less than 7 % of currently available suitable habitat. Results also indicate that the amount of golden mantella habitat falling within protected areas decreases by 86 % over the same period. We recommend research to ascertain future viability and the feasibility of expanding protection to newly identified potential sites. This information can then be used in future conservation actions such as habitat restoration, translocations, re introductions or the siting of further wildlife corridors or protected areas.

Rensch’s rule describes sexual size dimorphism (SSD) that decreases with increasing body size when females are larger than males and SSD that increases when males are larger than females. The plateau brown frog Rana kukunoris, a species endemic to the eastern Tibetan Plateau, exhibits female-biased size dimorphism. Using data on body size from 26 populations and age from 21 populations, we demonstrated that SSD did not increase with increasing mean female snout-vent length (SVL) when controlling for sex-specific age structure, failing to support the Rensch’s rule. Thus, we suggest that fecundity selection (favouring large female size) balances out sexual selection (favouring large male size), which results in a similar divergence between males and females body size. In addition, sex-specific age differences explained most of the variation of SSD across populations.
