Stigma of tiger attack: Study of tiger-widows from Sundarban Delta, India

How effective are interventions to reduce attacks on people from large carnivores? A systematic review protocol

BACKGROUND

Instances of attacks from large carnivores that lead to human injury or death are increasingly reported worldwide. Ensuring human safety when people and carnivores co-occur is central to minimizing human suffering but is also essential to support sustainable carnivore conservation. Various interventions are available intended to alter either the behavior of large carnivores or people, in order to reduce the likelihood of a risky encounter and an attack. Collated evidence on best practices is still lacking, and this protocol outlines a systematic review of evidence for intervention effectiveness to reduce the risk or severity of direct attacks on humans by large carnivores. Specifically, the review seeks to answer the question: How effective are evaluated interventions in reducing large carnivore attacks on people?

METHODS

The bibliographic databases Zoological Record, BIOSIS Citation Index, and Scopus will be searched using a predefined search string. Grey literature will be requested through professional networks, contacts with relevant organizations, and searching selected websites. All returned titles and abstracts will be manually screened using Rayyan.ai. For inclusion, studies should describe the Population, Intervention, Comparator, and Outcome (PICO) of the review research question and be written in English, Spanish, or Swedish. Review papers will be excluded. All records of data coding and extraction are documented in a purposely developed, and priorly piloted, data sheet. Critical appraisal of study validity will be done according to the Collaboration for Environmental Evidence Critical Appraisal Tool prototype version 0.3. Review outcomes will be synthesized in a narrative, and if possible, a quantitative synthesis. The narrative synthesis will describe in text the carnivore population (species, location), context (target object, intervention model), as well as the design and reported results of each study. The quantitative synthesis will include a summary statistic, preferably logarithmic risk ratio, calculated for each original study. A forest plot will be created to visualize study outcomes, as well as judgments of critical appraisal. Provided that enough data is available and that it complies with its assumptions, a meta-regression analysis will be undertaken using metafor package for R software.

COVID-19 lockdown and distressed reverse migration enhance human-tiger conflict in Sundarban: An eco-psychiatric observation

COVID-19 lockdown enforced distressed reverse migration in Sundarban, which caused an unprecedented population addition to the already devastated fragile Sundarban ecosystem. Acute poverty and food crisis prompted many migrants to explore forest-based living, thus enhancing fatal human-tiger conflicts. Families of deceased migrants face significant mental health trauma and catastrophic psychosocial consequences.

Fatal captive tiger attack - A case report with review of literature

The attacks on humans by big captive felids has been an issue of concern for the administration of zoological parks and wildlife conservationists. The theme of human-animal conflict takes a new dimension for the wild animals kept in zoos, circuses, exotic animal farms, and private custody. Despite the potential dangers involved, the zookeepers have to closely interact with the captive tigers for catering to the needs of food, general health, and wellbeing. The literature has described cases of attacks by captive tigers resulting in the death of the primary caretaker. The injuries present on such bodies include multiple punctured lacerations, traumatic amputations, damage to the vital organs of the neck, fracture-dislocation of cervical vertebrae, and abrasions secondary to the dragging of the body. We present a rare fatal case of an attack of a tiger on keeper during the night hours while he entered the cage to look after the tiger who was suffering from gastroenteritis for a few days and was not taking his feed aptly. The keeper had a twelve-year long relation with the tiger, and the discovery of his death was an astonishment for zoo administration. This case describes the autopsy findings emphasizing the distribution of injuries, along with inquiring into the scene of the incident. The details about the predatory behaviour of tigers and stereotypic behaviours in captivity have been discussed.

Direct and indirect psychological impacts of shark-bite events

OBJECTIVE

Shark bites are rare, with intense media exposure. There are no known studies of the psychological impacts of this specific type of traumatic event. This is the first study that describes those directly and indirectly affected, and evaluates the prevalence of post-traumatic stress disorder (PTSD) and related risk factors.

METHODS

In total, 124 members of an Australian shark-bite peer-support group were invited to complete an online survey assessing demographic, event, media and psychological factors. Response rate was 48% ( n = 60, 63% male, 44 ± 14 years). Retrospective and current measures of PTSD (PTSD Checklist for DSM-5 [PCL-5]) and suicidality (Suicidal Ideation Attributes Scale [SIDAS-5]) were used.

RESULTS

Post-event PTSD was prevalent in this sample ( n = 16/59, 27.1%, 95% confidence interval [CI] = [15.4, 38.8]), but less so currently ( n = 2/55, 3.6%, 95% CI = [0.0, 8.7]). In addition, nine ( n = 9/59, 15.3%, 95% CI = [5.8, 24.7]) had subthreshold, but highly symptomatic, syndromes post event. There was no association of PTSD with direct/indirect bite involvement, gender, or prior trauma. Two respondents were at risk of suicidal behaviour. PTSD was commonly reported by those without a partner (odds ratio [OR] = 5.91, 95% CI = [1.52, 22.99], p = 0.01) or with two friends or fewer to rely on (OR = 5.83, 95% CI = [1.62, 21.01], p = 0.01). PTSD was more likely in those with a negative media experience ( n = 34/52, 65.4%, OR = 11.90, 95% CI = [1.42, 100.04], p = 0.02) and 61.5% ( n = 32/52) of respondents reported media coverage lasting months or years. In multivariate modelling, negative media impact, relationship status and friendships were independently associated with PTSD and explained much of the variance in PTSD ( F_4,41 = 10.94, p < 0.0001, r² = 0.52).

CONCLUSION

Nearly one-third of members of an Australian shark-bite peer-support group report post-event PTSD, and one-quarter of these were not present at the time of the event. Findings support interventions targeting negative media impact, similar to media reporting guidelines for suicide, and enhancing social support.
