In the present study, we updated the taxonomy and distributional data for 14 carnivore species based on previous records and the recent results of camera trapping (4787 camera nights from 58 locations) and depicted species richness. We then identified threats and the conservation measures that are practiced to ensure the protection of the carnivores of Saudi Arabia. A total of 10 species of carnivores (Canis aureus, Canis lupus, Caracal caracal, Felis lybica, Genetta genetta, Hyaena hyaena, Ichneumia albicauda, Mellivora capensis, Vulpes cana, and Vulpes vulpes) were recorded based on camera trapping efforts. The striped hyena was the most recorded species in 13 locations, with the highest number of observations made at Raydah Protected Area, followed by the red fox and the Arabian wolf. Both Genetta genetta and Mellivora capensis were the least recorded species. Vulpes vulpes was the most distributed species and it was recorded from 15 sites. The southwestern corner of Saudi Arabia covering the Asir, Jazan, and Najran Plateaus extending further into the Al Sarawat Mountains hosts the highest number of carnivore species. Major threats affecting carnivores include killing and animal trade. The status of the critically endangered species, Panthera pardus nimr, was discussed. Threats and the conservation status based on regional assessment according to the IUCN Red List of the carnivores of Saudi Arabia were documented and highlighted.

The Arabian leopard Panthera pardus nimr is categorized as Critically Endangered, with < 200 individuals estimated to remain in the wild. Historically the species ranged over an extensive area of western Saudi Arabia but, with no confirmed sightings since 2014, investigating potential continued presence and distribution is of critical conservation importance. We present the results of a comprehensive survey designed to detect any remaining Arabian leopard populations in Saudi Arabia. We conducted 14 surveys, deploying 586 camera-trap stations at 13 sites, totalling 82,075 trap-nights. Questionnaire surveys were conducted with 843 members of local communities across the Arabian leopard's historical range to assess the presence of leopards, other predators and prey species. Predator scats were collected ad hoc by field teams and we used mitochondrial DNA analysis to identify the originating species. We obtained 62,948 independent photographs of animals and people, but none were of Arabian leopards. Other carnivores appeared widespread and domestic animals were numerous, but wild prey were comparatively scarce. Three questionnaire respondents reported sightings of leopards within the previous year, but targeted camera-trap surveys in these areas did not yield evidence of leopards. Of the 143 scats sent for analysis, no DNA was conclusively identified as that of the leopard. From this extensive study, we conclude there are probably no surviving, sustainable populations of Arabian leopards in Saudi Arabia. Individual leopards might be present but were not confirmed. Any future Arabian leopard conservation in Saudi Arabia will probably require reintroduction of captive-bred leopards.

BackgroundMany studies have been conducted worldwide and in the Kingdom of Saudi Arabia (KSA) during the current coronavirus disease 2019 (COVID-19) pandemic to assess the factors affecting COVID-19 vaccine acceptance. However, only some of these studies have adopted the Health Belief Model (HBM). This study aimed to assess the demographic characteristics and socio-psychological variables affecting the willingness to receive the COVID-19 vaccine among the general adult population in the KSA using the basic elements of the HBM.MethodsA cross-sectional survey-based study was conducted. A Google Form questionnaire comprising 30 questions was distributed electronically using social media platforms. A univariate analysis using chi-square testing identified candidate variables for the multivariate logistic regression at a p-value of <.05 at 95% confidence interval (CI) set as a cut-off point. Multivariate logistic regression analysis was used to determine the association between multiple predictor variables and the dichotomized COVID-19 vaccine acceptance variable.ResultsA total of 1939 individuals participated in the current study. More than 73% were willing to take the vaccine, while the rest were either not willing (14.6%) or not sure (12.1%). The results showed that men were 1.29 times more likely to receive the COVID-19 vaccine than women (odds ratio, or OR = 1.29, 95% CI = 1.01-1.64, p = .04); those who were or had been a healthcare worker (HCW) were 1.43 times more likely to receive the COVID-19 vaccine compared with those who had never been a HCW (OR = 1.43, 95% CI = 1.10-1.87, p = .01). We found that perceiving the risk of contracting COVID-19 (OR = 2.86, 95% CI = 1.47-5.55, p = .00) and perceiving the severity of the disease (OR = 2.07, 95% CI = 1.08-3.96, p = .03) were positively associated with the willingness to receive the vaccine. Perceived barriers such as ineffectiveness of the vaccine (OR = 0.28, 95% CI = 0.18-0.44, p < .001), or believing the vaccine is just a media advertisement (OR = 0.56, 95% CI = 0.35-0.87, p = .01) were negative predictors of acceptance of the vaccine. Moreover, perceiving the benefits, such as life going back to normal (OR = 2.28, 95% CI = 1.37-3.77, p = .00) and recognizing the importance of the annual flu vaccine (OR = 3.43, 95% CI = 2.29-5.14, p < .001), were found to be positive predictors of acceptance of the vaccine. Finally, we also found that cues to action were positively associated with vaccine acceptance, that is, participants who were encouraged by their doctors (OR = 1.75, 95% CI = 1.17-2.60, p = .01), and family members or friends (OR = 2.89, 95% CI = 1.94-4.32, p < .001) were more willing to receive the COVID-19 vaccine than those who were not.ConclusionsThe current study provides valuable insights into the determinants of vaccine acceptance and hesitancy based on the HBM from a cognitive perspective. This could be useful in helping the government establish public health programs aimed at addressing barriers and false beliefs among the adult population, which could enhance the public’s willingness to receive COVID-19 vaccines and, ultimately, accelerate achieving herd immunity.
