Their routes are “super different,” Delmore says. environment The sum of all of the things that exist around some organism or the process and the condition those things create.

At a site in California, the two species overlapped.
toxic Poisonous or able to harm or kill cells, tissues or whole organisms. terrain The land in a particular area and whatever covers it.

Now it’s your turn: Write a story or a scene from an animal’s perspective. docile An adjective meaning calm, cooperative, submissive or deferential. For example, the oxygen in the air is made of two oxygen atoms (O2), but water is made of two hydrogen atoms and one oxygen atom (H2O).
Afterward, they spit out unwanted parts — including electronic tags. But 41 percent of the hybrids’ tags also turned up in the nests. Indeed, the males often bit and scratched the females. salmon A popular game fish that tends to live most of its life in the ocean, then enters coastal rivers (and freshwater) to breed and lay eggs.
But if they return by a different path, those landmarks will be absent. bacteria (singular: bacterium) Single-celled organisms.

One difference between the two subspecies is their migration behavior. What’s exciting about hybrids is that you can think of each one “as a little bit of an experiment,” Matocq says. species A group of similar organisms capable of producing offspring that can survive and reproduce. These females may have avoided Bryant’s woodrats because those males were bigger and more aggressive.
breed (noun) Animals within the same species that are so genetically similar that they produce reliable and characteristic traits. Appearance is just one.
