Description

Technical Field

[0001] This invention relates to the field of endangered bird management, specifically to a system and method for enhancing the genetic diversity and population of endangered birds. Background Technology

[0002] In the field of endangered bird conservation, the management of endangered birds usually involves conventional methods such as building artificial nest boxes and feeding them. While these management methods can improve habitat conditions, they cannot actively intervene in the birds' mate selection. Due to the small population size and narrow distribution range of endangered birds, inbreeding is very likely to occur among individuals, leading to a continuous decline in genetic diversity and a decrease in the adaptability of offspring, which seriously hinders the natural recovery of the population. Therefore, we propose a genetic diversity enhancement and population management system and method for endangered birds. Summary of the Invention

[0003] The purpose of this invention is to provide a management system and method for enhancing the genetic diversity and population of endangered birds, which solves the technical problems mentioned in the background art.

[0004] The present invention achieves the above objectives through the following technical solutions: A genetic diversity enhancement and population management system for endangered birds includes a support frame, a movable bird nest movably mounted on the support frame, several groups of fixed bird nests fixedly mounted on the support frame and located along the movement path of the movable bird nest, a data collection and analysis unit for collecting and analyzing data on endangered birds in the movable and fixed bird nests to obtain genetic indication results, a linear drive device mounted on the support frame for controlling the movable bird nest to move to the corresponding fixed bird nest position according to the genetic indication results, and a docking and interconnection mechanism for docking and connecting the movable bird nest with the corresponding fixed bird nest.

[0005] A further improvement is that the movable bird nest and the fixed bird nest have the same structure; The active bird nest includes a main body, an entrance on one side of the main body for endangered birds to enter, a grid plate inside the main body, a water trough and a feed trough on the inner walls of both sides of the grid plate and above the grid plate, a feed storage chamber and a water storage chamber on the top sides of the main body, and a ventilation device on the side wall of the main body. The feed storage chamber and the water storage chamber are connected to the water trough and the feed trough respectively through a pipe, and the pipe is equipped with a solenoid valve.

[0006] A further improvement is that the acquisition and analysis unit includes a sample acquisition mechanism mounted on a support frame for collecting biological samples of endangered birds in active and fixed bird nests, an image acquisition device mounted on the inner wall of the bird nest body for collecting image data of endangered birds, and an analysis module for analyzing the collected biological samples and image data of endangered birds to obtain genetic indication results. The biological samples include bird feathers and bird droppings, and the genetic indicators include bird sex, genetic diversity, and inter-individual kinship.

[0007] A further improvement is that the sample collection mechanism includes a limiting shell located below the support frame and having a hollow bottom, a carrier plate movably located within the limiting shell, several sets of sample cups embedded on the carrier plate, a telescopic device four located on the limiting shell for driving the carrier plate to rise and fall, and a magnetic fixing component for detachably fixing the output end of the telescopic device four and the carrier plate. The bird's nest body is connected to a micro vacuum pump through a discharge pipe. The micro vacuum pump is located on the limiting shell and its output end is connected to one of the sample cups. A cleaning component is provided on the top side of the grating plate. The cleaning component is driven to move by a telescopic device on the bird's nest body to clean the grating plate. Inside the bird's nest body and below the grating plate, a guide plate is inclined to cooperate with the inlet end of the discharge pipe.

[0008] A further improvement is that the docking and interconnection mechanism includes a docking part one located on one side of the main body of the bird's nest in the movable bird's nest, and a docking part two located on one side of the main body of the bird's nest in the fixed bird's nest for cooperating with the docking part one.

[0009] A further improvement is that the docking part one includes a movable frame that is slidably inserted into the bird's nest body on the side away from the entrance. Two sets of sealing plates one for closing the movable frame are symmetrically inserted into the outer surface of the movable frame. The sealing plate one is connected to a sliding seat that is slidably disposed on the outer wall of the bird's nest body through a telescopic device two. The sliding seat is connected to the output end of a telescopic device three disposed on the outer wall of the bird's nest body. The telescopic device two is used to drive the sealing plate one to drive the movable frame to dock with the docking part two. The telescopic device three is used to drive the sliding seat to move horizontally, thereby driving the sealing plate one to open the movable frame through the telescopic device two. The sealing plate one is provided with a locking block.

[0010] A further improvement is that the second docking part includes a fixed frame that is fixedly inserted into the bird's nest body on the side away from the entrance and is used to dock with the movable frame. Two sets of sealing plates are symmetrically and movably inserted into the outer end surface of the fixed frame for closing the fixed frame. An elastic element for providing a restoring force is provided between the sealing plate and the fixed frame. The sealing plate is provided with a locking seat that engages with the locking block when the movable frame docks with the fixed frame. Both the first and second sealing plates are equipped with transparent windows.

[0011] A further improvement is that a material pipe is inserted at the top of the movable frame and on the side of the sealing plate away from the fixed frame, and a discharge pipe is inserted at the top of the fixed frame and on the side of the sealing plate away from the movable frame. The top of the discharge pipe is connected to a guide hopper. A storage box is provided on one side of the main body of the movable bird's nest. The output end of the storage box is connected to both material pipe one and an inclined material pipe two. The discharge end of material pipe two is used to be located above the guide hopper after the movable frame and the fixed frame are connected. A solenoid valve is provided at the output end of the storage box.

[0012] A further improvement is that the fixed bird nest has a rotating closed door on one side of the main body for opening or closing the entrance, and the support frame is also equipped with an image acquisition device for collecting image data and a voice playback device for playing sounds to attract endangered birds.

[0013] A method for enhancing genetic diversity and managing populations of endangered birds, utilizing the aforementioned system, includes the following steps: S1: The system is deployed in the habitat of endangered birds using a support frame, providing nesting and living space for endangered birds through mobile bird nests and multiple fixed bird nests; S2: The data of endangered birds in active and fixed nests are continuously collected and analyzed by the data collection and analysis unit to obtain genetic indication results; S3: Based on the genetic indication results, the linear drive device is controlled to move the mobile bird nest to the corresponding fixed bird nest. Then, the mobile bird nest is connected to the fixed bird nest through the docking and communication mechanism to realize the connection between the two, so that endangered birds with different genetic backgrounds can come into contact and pair up.

[0014] The beneficial effects of this invention are as follows: This invention establishes movable bird nests and multiple fixed bird nests, and combines this with a data collection and analysis unit to collect and analyze genetic data of the birds within the nests. Based on the obtained genetic indicators, it can automatically control the movable bird nests to move to the most suitable fixed bird nests, and achieve safe connection between the two nests through a docking and interconnection mechanism. This management system can proactively guide two genetically selected, distantly related endangered bird species to contact and pair up in the same space, thereby promoting gene recombination and gene flow, avoiding inbreeding depression, enhancing the environmental adaptability and long-term survival ability of endangered bird populations, and reducing the difficulty of artificial intervention and the disturbance to the birds.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1

[0019] Please see the appendix Figure 1-2A genetic diversity enhancement and population management system for endangered birds includes a support frame 1 (optionally, in this embodiment, the support frame 1 includes a rectangular frame plate and support rods located around the bottom of the rectangular frame plate for fixing to the ground in the habitat area of ​​endangered birds), a movable bird nest 2 movably mounted on the support frame 1, several sets of fixed bird nests 3 fixedly mounted on the support frame 1 and located along the movement path of the movable bird nest 2, and a collection and analysis unit mounted on the support frame 1 for collecting and analyzing endangered bird data (including endangered bird image data or biological sample data) from the movable bird nest 2 and the fixed bird nests 3 to obtain genetic indicator results. A linear drive device 6 for controlling the movement of the active bird nest 2 to the corresponding fixed bird nest 3 according to the genetic indication results (optionally, the linear drive device 6 in this embodiment includes a slider connected to the active bird nest 2, a groove provided on the support frame 1 for the slider to slide inside, a screw threaded through the slider and rotatably provided in the groove, and a servo motor provided on the support frame 1 and connected to one end of the screw), and a docking and communication mechanism 4 for docking and communicating with the active bird nest 2 and the corresponding fixed bird nest 3. It should be noted that each electrical component in this system is remotely connected to an external controller through a wireless communication module. For example, after analyzing the data collected from individuals in the active nest 2 and individuals in a fixed nest 3, if the genetic indicators of the two are determined to be compatible—that is, meeting preset preferred conditions such as complementary sex (one male and one female), distant kinship (not closely related), and suitable genetic background—then the external controller controls the linear drive device 6 to move the active nest 2 along the support frame 1 to the side of the matching fixed nest 3. Subsequently, the docking and interconnection mechanism 4 is activated to reliably dock the two nests and connect their internal spaces. This method actively guides two genetically selected, distantly related endangered birds to contact and pair up in the same space, thereby promoting gene recombination and gene flow, avoiding inbreeding depression, and enhancing the environmental adaptability and long-term survival ability of endangered bird populations. It should be noted that, in order to minimize interference to the birds, the above-mentioned nest movement and docking operations are preferably completed when the birds are away from their nests.

[0020] A method for enhancing genetic diversity and managing populations of endangered birds, utilizing the aforementioned system, includes the following steps: S1: The system is deployed in the habitat of endangered birds through the support frame 1, and provides nesting and living space for endangered birds through the mobile bird nest 2 and multiple fixed bird nests 3; S2: The data of endangered birds in active nests 2 and fixed nests 3 are continuously collected and analyzed by the data collection and analysis unit to obtain genetic indication results; S3: Based on the genetic indication results, the linear drive device 6 is controlled to move the mobile bird nest 2 to the corresponding fixed bird nest 3. Then, the mobile bird nest 2 and the fixed bird nest 3 are connected through the docking and interconnection mechanism 4 to realize the connection between the two, so that endangered birds with different genetic backgrounds can come into contact and pair up.

[0021] Example 2

[0022] Please see the appendix Figure 3 Based on Example 1, the movable bird nest 2 and the fixed bird nest 3 in this example have the same structure; The active bird nest 2 includes a main body 21, an entrance on one side of the main body 21 for endangered birds to enter, a grid panel 22 inside the main body 21 (to facilitate the separation and collection of fallen feathers, droppings, etc.), a water trough 23 and a feed trough 24 respectively located on the inner walls of both sides of the grid panel 22 and above the grid panel 22, a feed storage chamber 25 for storing feed and a water storage chamber 26 respectively located on the top sides of the main body 21, and a ventilation device on the side wall of the main body 21 (in this embodiment, the ventilation device can be a low-noise fan to ensure the safety of the bird nest). (Air circulation in the storage chamber). The bottom of the storage chamber 25 and the water storage chamber 26 are respectively connected to the water tank 23 and the feed tank 24 through a pipe. The pipe is equipped with a solenoid valve. By controlling the opening and closing of the solenoid valve, the feed and water can be automatically replenished. Furthermore, the top of the bird nest body 21 in this embodiment is also provided with a feed inlet and a water inlet that are respectively connected to the storage chamber 25 and the water storage chamber 26. They can be sealed with a sealing cover in normal times. The movable bird nest 2 and the fixed bird nest 3 provide a comfortable nesting and living space for endangered birds, so as to better manage the population of endangered birds and improve their genetic diversity.

[0023] Please see the appendix Figure 1-3 As a preferred embodiment, the acquisition and analysis unit includes a sample collection mechanism 5 mounted on a support frame 1 for collecting biological samples of endangered birds in active bird nests 2 and fixed bird nests 3; an image acquisition device 7 (such as a low-light camera, etc., for continuously recording morphological and behavioral image data of endangered birds in the bird nest) mounted on the inner wall of the bird nest body 21 for collecting image data of endangered birds; and an analysis module for analyzing the collected biological samples and image data of endangered birds to obtain genetic indication results. The working principle of the analysis module in this embodiment is as follows: the biological samples are sent to the laboratory for DNA extraction, targeted gene amplification (such as using the CHD gene for sex identification, and using microsatellites or SNP markers for genotyping) and sequencing analysis; at the same time, the image data is used to perform individual identification and behavioral analysis through computer vision algorithms; then, based on bioinformatics methods, the kinship between individuals is calculated, the genetic diversity level of the population and individuals is assessed, and genetic indication results are generated by integrating sex information. The biological samples include bird feathers and bird droppings. The genetic indicators include bird sex, genetic diversity, and inter-individual kinship. Specifically, bird sex identification involves accurately determining whether an individual is male or female by analyzing sex-linked genes such as CHD. Genetic diversity involves quantifying the level of genetic variation in the population and individuals using microsatellite markers or single nucleotide polymorphism (SNP) genotyping techniques, including indicators such as allele richness and heterozygosity, to reflect the genetic health status of the population. The third aspect is inter-individual kinship, which involves calculating the kinship coefficient between different individual biological samples by comparing their data. By comparing the genetic indicators of individuals in active nest 2 with those of individuals in a fixed nest 3, it can be determined whether the two are suitable for contact and pairing.

[0024] Please see the appendix Figure 2-4 As a preferred embodiment, the sample collection mechanism 5 includes a limiting shell 51 located below the support frame 1 and with a hollow bottom (which can be a bracket located below the support frame 1 near the ground), a carrier plate 52 movably located within the limiting shell 51, several sets of sample cups embedded in the carrier plate 52 (the number of sample cups is the sum of the fixed bird nest 3 and the movable bird nest 2), a telescopic device 53 (such as an electric telescopic rod) located on the limiting shell 51 for driving the carrier plate 52 to rise and fall, and a magnetic fixing component 55 for detachably fixing the output end of the telescopic device 53 and the carrier plate 52 (optionally, the magnetic fixing component in this embodiment includes an electromagnetic block located at the output end of the telescopic device 53 and a permanent magnet block embedded in the carrier plate 52). The bird nest body 21 is connected to a micro vacuum pump 54 through a discharge pipe. The micro vacuum pump 54 is located on the limiting shell 51 and its output end is connected to one of the sample cups. A cleaning component 29 (such as a cleaning brush or air blower) is provided on the top side of the grating plate 22. The cleaning component 29 is driven to move by a telescopic device 28 (such as an electric telescopic rod) provided on the bird nest body 21 to clean the grating plate 22. A guide plate 27 for cooperating with the inlet end of the discharge pipe is provided at an angle inside the bird nest body 21 and below the grating plate 22. When birds leave their nests, the telescopic device 28 drives the cleaning component 29 to clean the grid plate 22, causing biological samples such as feces and feathers attached to it to fall onto the guide plate 27 and slide into the discharge pipe. Then, the corresponding micro vacuum pump 54 is activated to draw the samples and transport them to the corresponding sample cups for temporary storage. After all sample cups have been collected, the operator can operate external equipment (such as an unmanned vehicle) to move below the limiting shell 51, and then control the telescopic device 53 to lower the carrier plate 52 and separate it through the magnetic fixing component 55. The carrier plate 52 is then transported by an unmanned vehicle or manually to complete the centralized collection of samples, ensuring the accurate correspondence between the samples and the source bird nests, and providing a high-quality sample source guarantee for subsequent analysis.

[0025] Please see the appendix Figure 2 As a preferred embodiment, the fixed bird nest 3 in this embodiment has a rotating closing door 9 on one side of the bird nest body 21 for opening or closing the entrance. The rotating closing door 9 in this embodiment includes a rotating device embedded in the outer wall of the bird nest body 21 and a door body connected to the output end of the rotating device for closing the entrance. The support frame 1 is also provided with an image acquisition device 2 10 (such as a camera) for acquiring image data, and a voice playback device 8 for playing sounds that attract endangered birds (pre-recorded sounds or adaptive audio signals generated based on ecological acoustic analysis can be selected to play according to the behavior of different species). When in use, the voice playback device 8 can play the calls or courtship sounds of the target endangered birds to attract individuals to fly closer and explore the system. The image acquisition device 10 continuously records images of endangered bird activity and environmental images in the area surrounding the support frame 1. The rotating closed door 9 enhances the protection capabilities and intervention flexibility for endangered birds in severe weather, predator interference, or specific management stages.

[0026] It should be noted that the data acquired by image acquisition device 7 and image acquisition device 10 in this application are all sent to an external monitoring terminal for processing via a wireless communication module, which will not be described in detail here.

[0027] Example 3

[0028] Please see the appendix Figure 5 Based on Embodiment 2, the docking and interconnection mechanism 4 of this embodiment includes a docking part 41 located on one side of the bird's nest body 21 in the movable bird's nest 2, and a docking part 42 located on one side of the bird's nest body 21 in the fixed bird's nest 3 for cooperating with the docking part 41.

[0029] Please see the appendix Figure 5-7 Preferably, in this embodiment, the docking part 41 includes a movable frame 411 slidably inserted into the bird's nest body 21 on the side away from the entrance (in this embodiment, the movable frame 411 has a slider on its outer wall, an opening on one side of the bird's nest body 21, and a groove that cooperates with the slider on the inner wall of the opening). Two sets of sealing plates 412 for closing the movable frame 411 are symmetrically and movably inserted into the outer end surface of the movable frame 411 (the length of which is greater than half the length of the inner cavity of the movable frame 411). The sealing plates 412 are connected by a telescopic device 414 ( The sliding seat 413, which is slidably installed on the outer wall of the bird's nest body 21, is connected to the output end of the telescopic device 415 (such as an electric telescopic pole) installed on the outer wall of the bird's nest body 21. The telescopic device 414 is used to drive the sealing plate 412 to drive the movable frame 411 to dock with the docking part 42. The telescopic device 415 is used to drive the sliding seat 413 to move horizontally, thereby driving the sealing plate 412 to open the movable frame 411 through the telescopic device 414. The sealing plate 412 is provided with a locking block 416. Preferably, the docking part 2 42 in this embodiment includes a fixed frame 421 fixedly inserted into the bird's nest body 21 on the side away from the entrance and used to dock with the movable frame 411. Two sets of sealing plates 2 422 (whose length is greater than half the length of the inner cavity of the fixed frame 421) are symmetrically and movably inserted into the outer surface of the fixed frame 421 for closing the fixed frame 421. An elastic element 423 (such as a spring) is provided between the sealing plate 2 422 and the fixed frame 421 to provide a restoring force. Specifically, one end of the elastic element 423 is connected to the outer end of the sealing plate 2 422 and the other end is connected to the outer wall of the fixed frame 421. The sealing plate 2 422 is provided with a locking seat 424 that engages with the locking block 416 when the movable frame 411 docks with the fixed frame 421. Both sealing plate 1 412 and sealing plate 2 422 are fitted with transparent windows 43.

[0030] When the movable bird nest 2 and the fixed bird nest 3 are connected, the telescopic device 2 414 drives the sealing plate 1 412 to move the movable frame 411 towards the fixed frame 421. When the movable frame 411 and the fixed frame 421 come into contact, the telescopic device 2 414 stops, and the locking block 416 engages with the locking seat 424. During the initial connection phase, the individual birds inside the two nests can observe each other through the transparent windows 43 set on the movable frame 411 and the fixed frame 421 respectively to gradually adapt. Subsequently, the telescopic device 3 415 drives the sliding seat 413 to move horizontally outward a certain distance, thereby driving the telescopic device 2 414 to move the movable frame 411 towards the fixed frame 421. The first sealing plate 412 opens the movable frame 411. The movement of the first sealing plate 412, through the locking block 416 and the locking seat 424, drives the second sealing plate 422 to open the fixed frame 421. By controlling the telescopic device 3 415, the opening range of the first sealing plate 412 and the second sealing plate 422 is gradually expanded in stages, and finally the internal spaces of the two bird nests are completely connected. This staged and gradual docking process effectively reduces the intense stress response or aggressive behavior that may be caused by sudden direct contact between different individuals, and provides them with the necessary adaptation and familiarization process, thereby increasing the success rate of genetic pairing guidance while protecting the animals.

[0031] Preferably, in this embodiment, a feed pipe 418 is inserted at the top of the movable frame 411 and on the side of the sealing plate 412 away from the fixed frame 421, and a discharge pipe is inserted at the top of the fixed frame 421 and on the side of the sealing plate 422 away from the movable frame 411. The top of the discharge pipe is connected to a guide hopper 425. A storage box 417 for storing feed is provided on one side of the bird's nest body 21 in the movable bird's nest 2. The output end of the storage box 417 is connected to both the feed pipe 418 and an inclined feed pipe 419. The discharge end of the feed pipe 419 is positioned above the guide hopper 425 after the movable frame 411 and the fixed frame 421 are connected. A solenoid valve is provided at the output end of the storage box 417.

[0032] When the two nests are connected but the sealing plates 412 and 422 are not yet fully open, the solenoid valves can be periodically opened by an external controller. This allows the feed in the storage box 417 to be delivered through feed pipe 418 to the area near sealing plate 412 in the movable frame 411, and through feed pipe 419, feed hopper 425, and discharge pipe to the area near sealing plate 422 in the fixed frame 421. By using food as a positive induction medium, the birds at both ends are attracted to gradually move towards the sealing plates and explore. Through precise directional feeding, a positive behavioral association is established before connection, effectively reducing the birds' wariness and territorial aggression towards the new passage. This creates a safe and natural transition condition for their subsequent contact and interaction, thereby improving the success rate of genetically guided pairing.

[0033] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
