Scientists experimenting with the restoration of boreal peatlands in Canada have found that restoring bryophytes, through moss layer transfers and other methods, is. Ecosystem engineers modify their habitats through their own biology or by physically changing biotic and abiotic factors in the environment. Whether it is preventing soil erosion, keeping temperatures cooler, or keeping populations in check. Deer, peccaries, tapirs, iguanas, capybaras, armadillos, and monkeys are among the many kinds of animals that fall prey to jaguars. How can exotic species affect populations of native species? There would be a disbalance in the entire ecosystem as there would be a sudden surge in the prey population which would result in decreasing of food availability of herbivores, thereby causing the decline in the population of the species that are present in the lower trophic levels.
