The many species of tree frogs that inhabit forests in the eastern us maintain their genetic isolation from other species by several mechanisms, including "singing" slightly different songs. which type of isolating mechanism does this represent?
a. temporal isolationb. behavioral isolationc. ecological isolationd. mechanical isolation

b. behavioral isolation

Explanation:

It is a type of reproductive barrier that can lead to speciation. Behavioral behavior, such as mating rituals as in when two populations of the same species show some difference in behavior, typically in mating rituals

and signals.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
