Recruitment rate to the population has tripled since 2004, making it unlikely that lions are having an impact on Grevy’s zebras. Population trend of Grevy’s zebra indicates that the Kenya population may be stabilizing. Lions preyed on Grevy’s zebra significantly less than expected in 15 of 16 (94%) scenarios considered and lions preyed on Plain’s zebras as expected or significantly less than expected in 15 of 16 scenarios. We compared field-based estimates of predation rates on both zebras to random gas models of encounters that result in predation to ask if lions prey preferentially on Grevy’s zebra at a sufficient rate to drive population declines. We tracked lions to potential feeding sites to estimate predation rates on zebras. We used line transect surveys to estimate density of Grevy’s (0.71/km 2) and Plain’s (15.9/km 2) zebras, and satellite telemetry to measure movements for lions and both zebras. quagga, IUCN Red List Near Threatened) and Grevy’s zebra populations in a 2,105 km 2 area defined by lion movements. We examined effects of lion predation on Plain’s zebra ( E. Recently, concern about the impact of recovering predator populations on wildlife in Laikipia County, Kenya, has led to questions of whether lions ( Panthera leo, IUCN Red List Vulnerable) exert top-down pressure on Grevy’s zebra ( Equus grevyi, IUCN Red List Endangered). In cases of apparent competition where there are alternate abundant and rare prey species, rare species may decline further than expected or disappear altogether. When predators are removed or suppressed for generations, prey populations tend to increase and when predators are re-introduced, prey densities should fall back to pre-control levels.

Trachtenberg has also promised that Prey will still include plenty of Predator gadgets, even if the plasma caster isn't among them.Timothy G. Some promotional artwork and trailer images for Prey show the Predator with a shoulder holster strapped to his back, which could be designed for just such a weapon. Perhaps the 1700s Predator is wielding a more primitive version of the plasma caster, or perhaps it is a different type of weapon entirely with a similar locking mechanism. While trailers sometimes use footage that isn't included in the final movie, it seems more likely that these crosshairs are used for a different weapon. However, the Prey trailer does still feature the iconic triangular laser marks that the plasma caster used to target its foes. Again, this can be explained by this Predator coming from a less advanced society. For Prey's heroes equipped with bows and arrows, and maybe a musket at best, it was necessary to downgrade the Predator's weapons. In an interview, Trachtenberg explained that the plasma caster was one of the first things he changed about the iconic alien, describing it as too much of an " instant win button." In the original Predator, a heavily-armed group of modern mercenaries with near-superhuman muscles, led by Arnold Schwarzenegger's Dutch, was just barely able to take down a single Predator aimed with a plasma caster. Somewhat surprisingly, the Predator's most iconic weapon, the plasma caster, will not be present in Prey.
