The relationship between body mass and density within the habitat is generally

Early in the sucession process K-selected organisms often establish early on because they are better competitors and these early sucessional habitats are often very challenging.

Please review the results from this famous experiment and address the questions below.      When examining the diagrams above, which of the following statements summarizes the experiment?

By selectively breeding tobacco worms into three distinct lines (see image below). The high-plasticity line changed color rapidly from black to green after heat shock at ~27 degrees C, while in the low-plasticity line colors remained consistently dark. Through this experiment, scientists demonstrate that … 

During the industrial revolution the levels of airborne soot increased, which darkened tree trunks. This impacted the ability of the pepper moth to hide from their predators. Their phenotypes began to shift from predominantly white with dark markings to predominantly dark with light markings. This is an example of  ___________ selection. Your answer should be one word in lowercase letters.

The following plot shows the proportion of male geckos born to different family groups based on rearing temperature. This shows that unlike other gecko traits that are plastic, sex ratio shows very little plasticity.

Why do the flytcather’s appear different in the sympatric population?  

Chthamalus adults’ are poor competitors relative to Semibalanus, so they will generally be found where Semibalanus cannot.

The male golden frog is waving as an intraspecific signal. This means that 

What metric do we use to quantify diversity? __________________
