A behavioral monitoring system useful for the analysis of complex behaviors in a number of animal species. The monitoring systems of this invention allow continuous monitoring of feeding, drinking and movement of animals with high temporal and spatial resolution. In certain embodiments, the system comprises an enclosure comprising: an animal position indicator; a food consumption indicator; and a fluid consumption indicator, where the system reports behavioral data at a temporal resolution of 20 seconds or lower.

A decoy mounting and movement system for mounting a hollow animal species decoy and for simulating life-like movement of the animal species between a rest position and a vertically pivoted position which simulates feeding by the animal species having a decoy mounting stake formed of an elongate upper stake section and an elongate lower stake section interconnected via an elongate vertical return spring capable of bending along its length to create an angle between the upper and lower stake sections, the upper stake section dimensioned for insertion into the hollow of the decoy through an opening in its underside in communication with the hollow of the decoy, wherein the fulcrum for vertical pivoting of the decoy is positioned at the lower end of the upper stake section and the ratio D′ / D is less than 0.25, wherein D′ is the distance between the underside of the decoy and the fulcrum for vertical pivoting, and D is the length of the upper stake section.

The invention provides methods and reagents for detecting a chromosomal aberration in an animal chromosome or karyotype. One or more detectably-labeled chromosome-specific probes from a first animal species are hybridized to chromosomes of a second animal species. This results in a banding pattern that can be compared to the pattern found in a normal chromosome or karyotype.

Relatively powerful hand-held computing devices, Digital Signal Processors, Audio signal processing technology, voice recognition technology, expert systems, Hidden Markov Models, and / or neural networks are employed in a device capable of real-time automated species identification by listening to bird vocalizations in the field, analyzing their waveforms, and comparing these waveforms against known reference samples. An apparatus for identifying animal species from their vocalizations, comprises a source of digital signal representative of at least one animal candidate vocalization; a feature extractor that receives the digital signal, recognizes notes therein and extracts phrases including plural notes and that produces a parametric representation of the extracted phrases; and a comparison engine that receives the parametric representation of at least one of the digital signal and the extracted phrases, and produces an output signal representing information about the animal candidate based on a likely match between the animal candidate vocalization and known animal vocalizations. A computer-implemented method of identifying animal species, comprises: obtaining a digital signal representing a vocalization by a candidate animal; transforming the digital signal into a parametric representation thereof; extracting from the parametric representation a sequence of notes defining a phrase; comparing the phrase to phrases known to be produced by a plurality of possible animal species; and identifying a most likely match for the vocalization by the candidate animal based upon the comparison. The comparison engine or comparison function may use Hidden Markov Models, expert systems and / or neural networks.

The invention provides methodologies for improved molecular genetic analysis of individual animals and animal populations. The invention includes methods and systems for identifying those animals in a population that are most likely to heritably pass on desirable traits. Provided are means for evaluating the estimated breeding values and increasing the average genetic merit for animals in a population. For each trait, the instant invention provides methods for evaluating the relative effect of one or more quantitative trait loci (QTL) and three or more molecular genetic markers for each QTL The relationship between these various markers and the pre-selected trait and QTL is calculated, along with the contribution of other factors such as pedigree and known measures with respect to quantitative trait, and these data are used to calculate estimated breeding values for the animals in the herd and to rank the animals according to these estimated breeding values.

It has been discovered that there are at least two significant antigens present on the cells of animal species such as pigs that elicit an immune or inflammatory response immediately upon implantation into humans or contact with human serum. The first is an α-galactosyl (Gal) epitope, for example, Galα(1−>3)Galβ(1−>4)GlcNac (linear B type 2) or Galα(1−>3)Galβ(1−>4)Glc (linear B type 6). The second is an N-glycolylneuraminic acid (NeuGc) structure. By eliminating these epitopes, preferably by genetically engineering the animal so that the epitope is either not produced or is greatly reduced, or by chemical or enzymatic treatment of the animal's cells to remove the epitopes, it is possible to produce organs, tissues and cells suitable for xenotransplantation into humans. Cells can be rendered even more compatible by genetically engineering the animal to express a human complement regulator protein (inhibitor), such as CD59, on its cells, or to express an excess of a pig complement regulatory protein.

A device is disclosed for attracting predetermined species of animals based on fractal geometry and the animal's own color perception. The device includes a planar object having at least two opposed faces and a shape unique to the fractal dimension of the predetermined animal species which the device is designed to attract. A light emitting surface is disposed on at least one face of the planar object. The surface is covered with light generating elements adapted to emit a light color based on color perception of the predetermined specific species, which color wavelength and brilliance is unnatural in normal surroundings relative to that species' own color perception. Finally, a mechanism is provided for mounting the object and enabling oscillatory-like movement in the object about an axis thereof.

The invention provides novel universal primers that can amplify the fragment of cytochrome b gene of any animal species in polymerase chain reaction (PCR) and reveal the identity of the biological material of any unknown animal origin and a method for identification of the specific animal from a given biological sample.
