Quinn y los demás lo encuentran justo a tiempo para detener a un par de sabuesos depredadores de atacar al chico. El Depredador aparece y los persigue hasta una escuela cercana donde deciden devolverle la armadura, pero cuando otro depredador aún más grande llega y mata al primero. Ellos huyen y el segundo Depredador comienza a buscar la tecnología perdida.
Tras analizar muestras de sangre alienígena Bracket concluye que los Depredadores están intentando mejorarse a sí mismos incluyendo ADN humano y de especies de otros planetas. Ellos huyen hacia un granero, pero Traeger los encuentra y los captura, compartiendo su teoría de que el cambio climático nos destruirá, lo que impedirá que los Depredadores puedan obtener ADN humano para futuras hibridaciones, por lo que intentan obtenerlo antes de que nos extingamos, también les explica que el primer depredador era un traidor que huyó para traer a la Tierra algún tipo de dispositivo muy valioso, por lo que el segundo fue enviado para detenerlo, destruir el dispositivo y eliminar cualquier pista de su presencia.
Al ver que Rory dibuja un mapa hacia la nave, Traeger se lo lleva para que lo guíe dando a sus hombres la orden de ejecutar a los demás. En paralelo, el segundo depredador ataca la casa de Emily, asesina a los agentes que la mantenían detenida y descubre entre las pertenencias de Rory otro mapa con la ubicación de la nave del primer depredador.
Tiempo después McKenna, ahora en el puesto de Traeger, llega a un laboratorio donde Rory los ayuda a comprender la tecnología yautja. Allí es informado que el dispositivo sobrevivió a la explosión de la primera nave y fue recuperado. Una pieza de tecnología flota fuera de su cápsula y rodea a un trabajador del laboratorio, notándose que esta tecnología funciona como un traje \"Matadepredadores\" antes de desactivarse, siendo una ayuda que el primer Depredador les dejó a los humanos para que luchen con los seres más grandes de su raza si éstos vuelven a la Tierra.
The prey naivety hypothesis posits that prey are vulnerable to introduced predators because many generations in slow gradual coevolution are needed for appropriate avoidance responses to develop. It predicts that prey will be more responsive to native than introduced predators and less responsive to introduced predators that differ substantially from native predators and from those newly established. To test these predictions, we conducted a global meta-analysis of studies that measured the wariness responses of small mammals to the scent of sympatric mammalian mesopredators. We identified 26 studies that met our selection criteria. These studies comprised 134 experiments reporting on the responses of 36 small mammal species to the scent of six introduced mesopredators and 12 native mesopredators. For each introduced mesopredator, we measured their phylogenetic and functional distance to local native mesopredators and the number of years sympatric with their prey. We used predator and prey body mass as a measure of predation risk. Globally, small mammals were similarly wary of the scent of native and introduced mesopredators; phylogenetic and functional distance between introduced mesopredators and closest native mesopredators had no effect on wariness; and wariness was unrelated to the number of prey generations, or years, since first contact with introduced mesopredators. Small mammal wariness was associated with predator-prey body mass ratio, regardless of the nativity. The one thing animals do not seem to recognize is whether their predators are native.
A diversity of animals survive encounters with predators by escaping from a looming visual stimulus. Despite the importance of this behavior, it is generally unclear how visual cues facilitate a prey's survival from predation. Therefore, the aim of this study was to understand how the visual angle subtended on the eye of the prey by the predator affects the distance of adult zebrafish (Danio rerio) from predators. We performed experiments to measure the threshold visual angle and mathematically modeled the kinematics of predator and prey. We analyzed the responses to the artificial stimulus with a novel approach that calculated relationships between hypothetical values for a threshold-stimulus angle and the latency between stimulus and response. These relationships were verified against the kinematic responses of zebrafish to a live fish predator (Herichthys cyanoguttatus). The predictions of our model suggest that the measured threshold visual angle facilitates escape when the predator's approach is slower than approximately twice the prey's escape speed. These results demonstrate the capacity and limits to how the visual angle provides a prey with the means to escape a predator.
Interspecific interactions between predators and prey have lead to a number of evolutionary adaptations that benefit predator and prey, such as pursuit-deterrent signals. These non-aggressive signals from prey to predator are advantageous for both: the predator wastes no energy on what would be an unsuccessful attack and the prey conserves energy by avoiding the need to escape. The blue-diademed motmot (Momotus lessonii) is a species that benefits from its pursuit-deterrent tail wag display, which tells predators that it is aware of their presence and is prepared to flee. The behavioral responses of M. lessonii in the Monteverde area to conspecific, predator, and control bird calls were quantified and compared. Subjects exhibited the pursuit-deterrent tail wag display and other predator avoidance behaviors in response to the predatory collared forest-falcon (Micrastur semitorquatus) call. They call continuously and approach more during conspecific calls as a form of territoriality, and may exhibit an extra territorial behavior in full tail wag displays. Finally, the control call of the white-throated robin (Turdus assimilis) had little effect on blue-diademed motmot behavior; they tended to continue typical behavior. These findings can shed light on pursuit-deterrent signaling and conspecific territorial displays, and suggest further research into conspecific calling by paired birds and possible extra territorial behavior. Las interacciones inter-específicas entre las presas y los depredadores han llevado a un número importante de adaptaciones que benefician tanto al depredador como a la presa, tales como las señales de disuasión. Estas señales no agresivas de la presa al depredador son ventajosas para ambos: el depredador no gasta energía en hacer un ataque inefectivo y la presa conserva la energía al evitar la necesidad de escapar. Momotus lessonii es una especie que se beneficia de su comportamiento de disuasión de menear la cola, el cual le indica al depredador que esta alerta de su presencia y está listo para volar. Las respuestas del comportamiento de M. lessonii en la región de Monteverde a los depredadores conspecíficos y las llamadas de control de las aves fueron cuantificadas y comparadas. Los individuos exhibieron el comportamiento de meneo de la cola y otros comportamientos de evasión en respuesta al llamado del depredador (Micrastur semitorquatus). Ellos cantan continuamente y se acercan durante los llamados de conspecíficos como una forma de territorialidad, y pueden exhibir un comportamiento extra territorial de meneo completo de la cola. Finalmente, el llamado de control de Turdus assimilis tiene poco efecto en el comportamiento del Momoto, ellos tienden a mantener un comportamiento típico. Estos resultados pueden correlacionar señales de disuasión y comportamientos de territorialidad con conspecíficos, y sugiere que se hagan futuros estudios entre los llamados de conspecíficos en parejas de aves y un posible comportamiento extra territorial.
Ruins under the ice of an ancient alien civilization are discovered in Antarctica. An expedition sponsored by the company Wayland is sent to investigate only to discover that what looks like a temple is truly a breeding ground for aliens that serve to train predators.
There is also a fantastically decorated Alien vs. Predator board game. It is a dungeon crawler full of miniatures where you will have to adopt the role of one of the three sides: marines, aliens or predators. It also has a cooperative version where humans and predators join against their common enemy: the aliens. A must for anyone who is fan of the saga and also like board games.
Their origin planet is unknown and it is speculated that they could have different colonies through the galaxy. In Alien vs. Predator 2 a Yautja city is shown on an arid planet with two suns that could be its main planet. In Predators move is shown a planet surrounded by other planets and moons that is used as a hunting ground by bad blood predators.
Yautja love hunting and have tendency towards hand-to-hand combat. In addition of the base equipment a predator can carry several other weapons that vary according to his personal choice:
In the Predators movie a kind of reptilian-looking and horned hound is used by the bad blood clan. Unlike their masters these mastiffs had red blood, so it is very possible that they were trained from the same planet that the predators used as a hunting ground.
In the predator movie appear other type of hound that have more similiar features to the Yautja and their blood is also green, so we can deduce that they are from the same predators natal planet.
This character that appears in the Alien vs. Predator comic has many fans (including myself). The comic history hooks from the first moment but I will not reveal the details because they are worth reading. The action figure is one of the best collecting pieces that one can have about predator.
En las películas no tienen un nombre concreto, por lo que se denomina a estas criaturas Yaut'jas, Hish, o simplemente Predators. Se dedican a viajar por la galaxia cazando a toda aquella criatura que sea digna de enfrentarse a sus habilidades y suponga un auténtico reto. El Depredator fue creado por Jim Thomas y John Thomas con una avanzada tecnología, como un camuflaje y armas de energía. 59ce067264
