For this analysis, population biologists have grouped species into the two large categories—K-selected and r-selected—although they are really two ends of a continuum.
If this is a spectrum or continuum, what is an example of a species that falls somewhere in the middle?

Females of these species mate only during the estrus phase of the cycle. A different pattern is observed in primates, including humans and chimpanzees, which may attempt reproduction at any time during their reproductive years,
It's interesting that although pronghorns and primates both technically fall under the category of k-strategists, they still instinctively mate at different points in their lives -- with some species only mating when in heat, and others engaging at any point.

The following year Darwin’s book, On the Origin of Species, was published. His book outlined in considerable detail his arguments for evolution by natural selection.
I just find it very interesting how famous Darwin and his works are, while Wallace remains in relative anonymity. We learn about Darwin and his accomplishments from a very young age, but not Wallace, even though they had very similar research and discoveries
-
Darwin’s journey, like Wallace’s later journeys to the Malay Archipelago, included stops at several island chains, the last being the Galápagos Islands west of Ecuador.
Why do we know and learn so much about Darwin, but not Wallace? I also find it interesting that Wallace's later journeys are mentioned but not Darwin's. Did Darwin not go on later journeys after his initial one?

To become an ecologist requires an undergraduate degree, usually in a natural science. The undergraduate degree is often followed by specialized training or an advanced degree, depending on the area of ecology selected. Ecologists should also have a broad background in the physical sciences, as well as a sound foundation in mathematics and statistics.
What are the most common majors and degrees of ecologists, I wonder? It seems like there is a range of options, I wonder what some of them are.
