Description

Technical Field

[0001] This involves the field of animal behavior training and rewilding adaptation technology, specifically the enhancement of the sense of smell during the rewilding training of captive South China tigers. Background Technology

[0002] The South China tiger (Panthera tigris amoyensis), a tiger subspecies endemic to China, is currently functionally extinct in the wild, and its conservation and management primarily rely on captive populations. For a long time, scholars both domestically and internationally have conducted extensive research on the conservation of the South China tiger, mainly focusing on genomics, conservation genetics, parasitology, infectious diseases, physiological ecology, nutritional ecology, behavioral ecology, and gut microbiota. For example, Fàbregas et al., through predation ability experiments in free-range environments, confirmed that captive South China tigers possess certain potential for rewilding; Liu Xiuqun et al.'s research showed that odor enrichment can effectively reduce stereotyped behaviors in captive South China tigers and increase the richness of their olfactory-related behaviors; Cao Qing et al., through behavioral observations of free-range South China tigers of different age groups, found that free-range environments can promote the partial recovery of South China tigers' wild survival behaviors.

[0003] However, existing research largely focuses on population-specific descriptions and conservation management, lacking systematic and quantifiable behavioral training programs and supporting assessment systems for systematically improving the wild adaptability of captive South China tigers and gradually achieving their transition from captivity to the wild. Specifically, the current captive environment restricts the natural development of the South China tiger's multi-sensory stimulation (olfaction, vision, and hearing), particularly failing to specifically strengthen its olfactory abilities, resulting in significant shortcomings in prey identification, behavioral learning, and wild survival skills. Furthermore, existing training or enrichment measures lack standardized procedures, systematic training content, and quantitative assessment methods, making it difficult to support an effective and controllable rewilding transformation path. They also cannot be dynamically adjusted based on individual training feedback, hindering the scientific evaluation and widespread application of training effectiveness.

[0004] In summary, existing technologies lack a systematic and phased process for training the South China tiger's olfactory abilities and enhancing its predatory behavior, as well as a multi-dimensional and quantitative evaluation system. Summary of the Invention

[0005] To address the shortcomings of existing technologies, such as the lack of a systematic and phased process for training olfactory abilities and enhancing predatory behavior specifically for the rewilding of South China tigers, as well as the lack of a multi-dimensional and quantitative evaluation system, the technical solution provided by this invention is as follows:

[0006] A method for enhancing the sense of smell in captive South China tigers during rewilding training includes the following steps:

[0007] The steps involved in collecting environmental parameters and basic individual behavioral data in a captive environment to form training environment assessment data.

[0008] Based on training environment assessment data, steps were taken to select suitable South China tiger individuals for training and record their health and behavioral status.

[0009] Develop a rewilding training program, clearly defining the steps for training cycles, duration of each training session, training frequency, and safety measures.

[0010] According to the training plan, the animals were stimulated with odor source items in a captive environment in stages, and the training was carried out in stages, including single odor stimulation, combined odor stimulation and multi-group odor differentiation training. Individual olfactory behavior data were obtained through each round of training.

[0011] The steps involve evaluating the improvement of an individual's olfactory ability based on the training data from each stage, adjusting the subsequent training content, and outputting basic data for the next stage of training.

[0012] After the captive training phase is completed and the individual South China tigers are moved into a free-range environment, the free-range training phase will be carried out.

[0013] In a free-range environment, various prey scent sources are regularly placed in a matrix arrangement, and the tigers' scent exploration, selection, identification, and behavioral responses are recorded through remote monitoring equipment to continuously strengthen their ability to recognize and remember prey scents.

[0014] During the free-range stage, live prey will be released further, either manually or by drone, to train the tigers' ability to pounce, capture, and bite prey. A comprehensive assessment and ability classification will be conducted based on their behavior.

[0015] The steps involve using quantitative behavioral recording and analysis to monitor and evaluate the entire process of improving olfactory and predatory abilities.

[0016] Furthermore, in a preferred embodiment, the environmental parameters include light intensity, temperature, humidity, vegetation cover, biodiversity, and human intervention parameters.

[0017] Furthermore, in a preferred embodiment, suitable South China tiger individuals for training are selected based on health examinations, individual behavioral performance assessments, and records of feeding behavior and stress responses.

[0018] Furthermore, in a preferred embodiment, the individual's basic behavioral status includes eating, exercising, and resting.

[0019] Furthermore, in a preferred embodiment, the training program includes presets for odor source types at each stage and presets for emergency measures.

[0020] Furthermore, in a preferred embodiment, the number of explorations and the recognition accuracy are used as criteria to assess the improvement of an individual's olfactory ability.

[0021] A device for enhancing the sense of smell in captive South China tigers during rewilding training is also provided, comprising the following modules:

[0022] A module for collecting environmental parameters and basic individual behavioral data in captive environments is formed to create training environment assessment data.

[0023] Based on training environment assessment data, suitable South China tiger individuals for training were selected, and modules for recording individual health and behavioral status were implemented.

[0024] Develop a rewilding training program, clearly defining modules such as training cycle, duration of each training session, training frequency, and safety measures.

[0025] According to the training plan, odor source objects were used to stimulate the animals in a captive environment in stages. The training was completed in stages, including single odor stimulation, combined odor stimulation and multiple odor differentiation training. Each round of training was used to obtain individual olfactory behavior data.

[0026] Based on the training data from each stage, the module assesses the improvement in an individual's olfactory ability, adjusts subsequent training content, and outputs basic data for the next stage of training.

[0027] After the captive training phase is completed and the individual South China tigers are moved into a free-range environment, a free-range training phase will be implemented.

[0028] In a free-range environment, various prey scent sources are regularly placed in a matrix arrangement, and the tigers' scent exploration, selection, identification, and behavioral responses are recorded through remote monitoring equipment to continuously strengthen their ability to recognize and remember prey scents.

[0029] During the free-range stage, live prey is further introduced through manual or drone-based methods to train tigers' ability to pounce, capture, and bite prey. A module for comprehensive evaluation and ability grading is also implemented based on behavioral performance.

[0030] This module uses quantitative behavioral recording and analysis to monitor and evaluate the entire process of improving olfactory and predatory abilities.

[0031] The system also provides a computer storage medium for storing a computer program, which, when read by the computer, executes the method.

[0032] A computer is also provided, including a processor and a storage medium, wherein the computer executes the method when the processor reads a computer program stored in the storage medium.

[0033] A computer program product is also provided, which, when executed, implements the method.

[0034] Compared with the prior art, the advantages of the technical solution provided by the present invention are as follows:

[0035] Through phased olfactory stimulation and intensive training, the South China tigers' ability to recognize and remember prey scents was systematically improved. Compared to traditional methods that rely solely on occasional scent stimulation in captivity or simple scent enrichment, this program developed standardized and procedural training content and cycles. It also employed combinations and rotations of different scent sources (such as feces, tissues, and blood) to effectively stimulate the South China tigers' desire to explore and identify diverse prey scents, thereby enhancing their prey location and foraging initiative.

[0036] During the free-range phase, the tigers' exploration, marking, and behavioral responses were quantitatively recorded and analyzed through a scientifically designed matrix of odor test items and environmental monitoring, further enhancing their ability to forage independently and adapt to unfamiliar environments. Unlike previous studies that only focused on reducing stereotypical behaviors or increasing behavioral diversity in captive animals, this approach, by continuously strengthening olfactory abilities in semi-free-range and free-range environments closer to nature, promoted the tigers' behavior towards wildness and improved their hunting skills.

[0037] Furthermore, by introducing live prey hunting and biting training, the program focuses on improving the South China tiger's hunting skills and survival abilities in the wild. Compared with existing training programs that rely solely on feeding dead meat or lack dynamic hunting elements, this program can more realistically simulate the wild survival environment, significantly improving the South China tiger's predation reaction speed, enhancing target selection and attack capabilities on key areas, and providing a behavioral foundation for eventual rewilding.

[0038] Finally, a multi-dimensional quantitative evaluation system was established, including indicators for physiological health, behavioral performance, psychological adaptation, and environmental adaptation. Combined with modern monitoring and data collection technologies, this system enabled scientific management and effect tracking throughout the training process. Compared with traditional methods that rely on human experience or subjective observation for evaluation, this system provides strong support for the objective evaluation of the effectiveness of rewilding training and for dynamic adjustments to individuals, significantly improving the scientific rigor, controllability, and scalability of rewilding training.

[0039] It is applicable to the rewilding training and behavioral enhancement of captive individuals of endangered big cats. Attached Figure Description

[0042] To make the advantages and benefits of the technical solution provided by the present invention clearer, the technical solution provided by the present invention will now be described in further detail with reference to the accompanying drawings, specifically:

[0043] Implementation Method 1: This implementation method provides a method for enhancing the sense of smell in captive South China tigers during rewilding training, including the following steps:

[0044] The steps involved in collecting environmental parameters and basic individual behavioral data in a captive environment to form training environment assessment data.

[0045] Based on training environment assessment data, steps were taken to select suitable South China tiger individuals for training and record their health and behavioral status.

[0046] Develop a rewilding training program, clearly defining the steps for training cycles, duration of each training session, training frequency, and safety measures.

[0047] According to the training plan, the animals were stimulated with odor source items in a captive environment in stages, and the training was carried out in stages, including single odor stimulation, combined odor stimulation and multi-group odor differentiation training. Individual olfactory behavior data were obtained through each round of training.

[0048] The steps involve evaluating the improvement of an individual's olfactory ability based on the training data from each stage, adjusting the subsequent training content, and outputting basic data for the next stage of training.

[0049] After the captive training phase is completed and the individual South China tigers are moved into a free-range environment, the free-range training phase will be carried out.

[0050] In a free-range environment, various prey scent sources are regularly placed in a matrix arrangement, and the tigers' scent exploration, selection, identification, and behavioral responses are recorded through remote monitoring equipment to continuously strengthen their ability to recognize and remember prey scents.

[0051] During the free-range stage, live prey will be released further, either manually or by drone, to train the tigers' ability to pounce, capture, and bite prey. A comprehensive assessment and ability classification will be conducted based on their behavior.

[0052] The steps involve using quantitative behavioral recording and analysis to monitor and evaluate the entire process of improving olfactory and predatory abilities.

[0053] Environmental parameters include light, temperature, humidity, vegetation cover, biodiversity, and human intervention parameters.

[0054] Suitable South China tiger individuals for training were selected based on health examinations, individual behavioral assessments, and records of feeding behavior and stress responses.

[0055] Individual basic behavioral status includes eating, exercise, and rest.

[0056] The training program includes presets for odor source types and emergency response measures at each stage.

[0057] The number of explorations and recognition accuracy were used as criteria to assess the improvement of an individual's olfactory ability.

[0058] Implementation Method Two: This implementation method is a further detailed description of the technical solution provided in Implementation Method One, specifically:

[0059] To address the issue of improving the rewilding ability of captive South China tigers, a systematic and phased training process is adopted, which includes the following steps:

[0060] 1. Basic survey of captive and free-range environments

[0061] First, a comprehensive survey of the captive environment was conducted, collecting basic parameters including natural environmental factors (such as light, temperature, humidity, vegetation cover, and biodiversity) and human factors (such as activity space, feeding methods, food composition, and frequency of human intervention). The health status, basic behavioral characteristics, and individual information of each South China tiger were also recorded. This survey yielded detailed training environment assessment data, providing a foundation for subsequent individual selection and training program development.

[0062] 2. Selection and basic assessment of training subjects

[0063] Based on the obtained environmental and individual parameters, and considering factors such as individual physiological state, behavioral performance, feeding status, and stress response, candidate South China tigers are screened to determine individuals suitable for the rewilding training phase. For individuals slated for training, health checks and behavioral assessments are also conducted to create preliminary individual behavioral capacity profiles, which will serve as a basis for comparing subsequent training progress and effectiveness.

[0064] 3. Development of a rewilding training program

[0065] Based on the above screening results, a detailed rewilding training plan was developed for each selected training subject. The plan included the training cycle, duration of each training session, training frequency, personnel arrangements, safety measures, and emergency response plans. These plans were reviewed and confirmed by experts in relevant fields to ensure that the training objectives were scientifically feasible, the process was controllable, and the ability to handle unforeseen circumstances was maintained.

[0066] 4. Olfactory training during the captive rearing stage

[0067] In captivity, South China tigers underwent multi-stage olfactory stimulation and reinforcement training according to a training program. The training adopted a progressive approach, starting with single prey odor stimuli and gradually expanding to combinations of prey odors. Scent sources were changed and training content adjusted according to the stage goals. After each training session, the tigers' behavioral responses, including exploration, localization, identification, and foraging, were monitored, and their performance was quantitatively recorded. Training strategies were continuously optimized based on the evaluation results.

[0068] 5. Olfactory enhancement and behavioral testing during the free-range stage

[0069] Individuals that achieved satisfactory training results during the captive rearing phase were transferred to a free-range area closer to their natural environment for further enhancement of their olfactory abilities and behavioral tests. In the free-range area, experimental items were scientifically arranged, with different types of prey scent sources being changed regularly. Through video monitoring and behavioral scoring, the tigers' scent recognition, exploration, selection, and activation behaviors were monitored to further strengthen their prey identification and proactive exploration abilities. After each set of experiments, the positions of the experimental items were randomly adjusted to examine the tigers' spatial memory and adaptability.

[0070] 6. Training in predatory behavior skills

[0071] Once the olfactory training has achieved the desired results, prey hunting ability training will begin. Live prey (such as pheasants and wild boars) will be dynamically released, either via drones or manually, to guide the tigers in autonomously hunting and biting. During training, the tigers' reaction speed, attack accuracy, and tendency to attack specific parts of the prey will be carefully recorded. Biting key parts of the prey (such as the throat) will be used as the criterion for success. The training will be continuously graded and quantified until the individual possesses comprehensive hunting abilities in the wild.

[0072] 7. Training process monitoring and data collection

[0073] Throughout the training process, individual physiological health data, behavioral performance, psychological reactions, and environmental adaptability were recorded in real time. GPS trackers were used to monitor the tigers' activity range and trajectory, combined with video surveillance and regular physical examinations to collect comprehensive data. The results of each training phase were quantitatively statistically analyzed to provide objective evidence for training adjustments and effectiveness evaluation.

[0074] 8. Training effect evaluation and dynamic adjustment

[0075] After the training, experts conducted a comprehensive evaluation of the effectiveness of the South China tiger rewilding training, covering aspects such as physical health, behavioral skills, and social adaptability. For individuals deemed suitable for long-term rewilding, the training program was adjusted appropriately, and the subsequent rewilding process continued. For individuals failing the evaluation, the problems were analyzed, and rewilding training was terminated promptly.

[0076] 9. Data processing and summarization

[0077] After all training phases are completed, the collected behavioral, physiological and environmental data will be systematically organized and statistically analyzed to provide data and theoretical support for the subsequent promotion and standardization of rewilding training techniques.

[0078] During the captive rearing phase, the olfactory abilities of the trainees are trained in stages and progressively. The specific process is as follows:

[0079] The first phase lasts for 9 days. A different odor source is selected each day, and the source is changed in a three-day cycle: prey feces on days 1-3, prey tissue on days 4-6, and prey blood on days 7-9. The designated odor source is exposed to the captive environment for 30 minutes each day, then promptly removed to prevent odor adaptation and ensure the freshness and effectiveness of the olfactory stimulation.

[0080] The second phase lasted for 9 days. Two different types of odor sources were introduced daily, with the combination changing every three days. The sequence was as follows: prey feces and tissue were introduced on days 1-3; prey feces and blood were introduced on days 4-6; and prey tissue and blood were introduced on days 7-9. Each introduction was followed by a 30-minute exposure period. During this time, the individual's exploration and reaction behaviors to the different odor combinations were closely observed and recorded.

[0081] The third phase lasted for 3 days. Three scent combinations were introduced daily: prey blood and feces, prey blood and tissue, and prey tissue and feces. Each combination was presented consistently for 3 days. Each combination was used for 30 minutes of exposure, during which the trainees' recognition behavior and selection preferences for each scent combination were closely recorded.

[0082] The fourth phase lasts for 3 days. Three single-type odor sources are introduced daily: prey blood, prey tissue, and prey feces, arranged in groups sequentially, with each odor rotating daily. Each exposure lasts 30 minutes, focusing on enhancing individuals' ability to distinguish between different odors, and their abilities are assessed through behavioral performance.

[0083] At each stage, trainers need to continuously assess changes in an individual's response to odor sources based on observation records, summarize and organize behavioral data, and provide data support for adjusting the content and optimizing the program in subsequent training stages. The entire olfactory training process follows a logic from easy to difficult, from single to combined and then to differentiation, gradually improving an individual's olfactory sensitivity, identification ability, and environmental adaptability.

[0084] Implementation Method 3: Combination Figure 1 This embodiment describes the technical solution provided above in further detail through specific examples. Specifically:

[0085] Pre-wilding individual assessment:

[0086] Before rewilding training, experts should be organized to conduct a pre-rewilding assessment and form an assessment conclusion to determine whether the target species is suitable for rewilding training.

[0087] Pre-rewilding assessments should comprehensively consider health examination results and interviews with conservation officers. The assessment should include, but is not limited to, the following:

[0088] The age and sex of the proposed wilding subjects;

[0089] Physical health condition;

[0090] Behavioral status, including:

[0091] Foraging behavior, individual behavior, social behavior, reproductive behavior, defensive behavior, aggressive behavior, etc.

[0092] Wilding training program development:

[0093] A rewilding training plan should be developed based on the specific circumstances of the trainees and approved by experts before implementation. The rewilding training plan should include, but is not limited to, the following:

[0094] Selection of personnel for rewilding training;

[0095] Duration of rewilding training period;

[0096] Duration of a single training session;

[0097] Safety measures for rewilding training;

[0098] Emergency response plan.

[0099] Implementation and monitoring of rewilding training:

[0100] (1) Implementation of wilding training

[0101] Wilding training should be implemented in accordance with the wilding training plan, and the plan should be adjusted and improved in a timely manner according to the actual situation.

[0102] To reduce the dependence of those undergoing rewilding training on humans, the training personnel should be relatively fixed. During the rewilding training process, contact between other personnel and the trainees should be minimized.

[0103] (2) Monitoring

[0104] During the rewilding training phase, the rewilding trainers should monitor the subjects. Monitoring of the subjects should include, but is not limited to, the following:

[0105] Food intake situation;

[0106] Health status after feeding;

[0107] Individual behavior;

[0108] Community behavior with other individuals;

[0109] Is there an emergency?

[0110] Effectiveness evaluation:

[0111] After the rewilding training expires or is terminated, experts should be organized to evaluate the effectiveness of the rewilding and form an evaluation conclusion. The evaluation conclusion may include: long-term rewilding or termination of rewilding.

[0112] The evaluation of the rewilding effect should include, but is not limited to, the following:

[0113] Physical health condition;

[0114] Behavioral status, including:

[0115] Foraging behavior, individual behavior, social behavior, reproductive behavior, and whether an emergency occurs.

[0116] Long-term rewilding and termination of rewilding:

[0117] For those subjects whose rewilding effectiveness assessment concludes as long-term rewilding, the rewilding plan can be appropriately adjusted, and rewilding training can continue according to the plan.

[0118] For those whose rewilding effectiveness assessment concludes that rewilding should be terminated, the existing problems should be analyzed and rewilding training should be terminated.

[0119] The olfactory stimulation and enhancement process in captive populations involves the following aspects:

[0120] Training in captive areas is shown in Table 1:

[0121] Table 1

[0122]

[0123] Free-range training (9 days):

[0124] Environmental setup: In the free-range area, nine scent release points (spaced 3-5 meters apart) are arranged in a 3×3 rectangular grid. These scent release points are randomly assigned with prey feces, tissue, or blood (single or mixed). The arrangement is as follows: Figure 2 As shown.

[0125] Infrared cameras were installed around the rectangular area for monitoring.

[0126] Implementation method: Change the scent combination at the scent placement point daily and record the tiger's exploration, marking and attack behavior.

[0127] Olfactory testing and reinforcement during the free-range stage:

[0128] Individuals that meet the training criteria in captive populations are placed in free-range areas for olfactory testing and reinforcement. A matrix of experimental items is purposefully and scientifically deployed, and the tigers' behavioral responses are observed through monitoring or fixed-point surveillance. The experimental items are camouflaged, and infrared cameras are deployed to record their behavior; 3-6 sets of experiments are conducted.

[0129] Test items containing the prey's blood, feces, and tissue are placed 3 to 5 meters apart. A matrix is ​​set up accordingly. Each test lasts three days. The contents of the matrix are fixed for each test. The contents are changed daily (the same contents are used). After a test is completed, the positions of the matrix items are randomly changed, and the next test begins.

[0130] Training of predation skills during free-range rearing:

[0131] After the above-mentioned olfactory training is completed, prey food training will be conducted based on the results achieved. Live prey (using wild boar as an example) will be thrown and its body divided into sections. The tiger's bite points will be used as scoring points for training effectiveness. A successful bite to the throat is considered a successful outcome, indicating the animal has acquired basic survival skills in the wild.

[0132] Finally, in this embodiment, the usage and dosage of prey tissue, prey blood, and prey feces that can be referenced are as follows:

[0133] Prey tissue: 200 grams per training session, stored frozen, and thawed to room temperature before use.

[0134] Prey blood: Use 30 ml per training session. To prevent rapid clotting that could affect storage and odor evaporation, dilute the blood with 10% saline solution at a volume ratio of 2:1 before use. Store the diluted blood in a sealed container at 2–6°C for no more than 5 days.

[0135] Prey feces: Take 30 grams for each training session. Fresh samples are required, maintaining their natural moisture and original texture, and should be used directly.

[0136] The above description of several specific embodiments further details the technical solution provided by the present invention in order to highlight the advantages and benefits of the technical solution provided by the present invention. However, the above-described specific embodiments are not intended to limit the present invention. Any reasonable modifications and improvements to the present invention, combinations of embodiments, and equivalent substitutions based on the spirit and principles of the present invention should be included within the protection scope of the present invention.
