Abstract:

Climate dynamics on our planet drive range border movements for many species. Insects, being ectothermic animals, significantly respond to changes in these conditions. We recently demonstrated northward expansion for important invasive pest species such as Lymantria dispar in central Asia. In the current study, we combined historical data and our modern data, using very sensitive pheromone trapping, to estimate the dynamics of the northern range border of Lymantria dispar.

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Migration

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
