View Available Hint(s) Jenkins and Buikema tested the Clements-Gleason dichotomy by . artificially creating sterile ponds and looking at how community structure developed as plankton species colonized the ponds studying logged forest clear-cuts and looking at the sequence of plants that colonized the clear-cuts creating artificial, harmless mimics of toxic species and comparing survival rates of the toxic species and the mimics introducing predatory crabs to aquaria and looking at resulting adaptations of prey species

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
