Evolution of projeny size
Fox, C. W., & Czesak, M. E. (2000). Evolutionary ecology of progeny size in arthropods. Annual review of entomology, 45(1), 341-369. Projeny could be due to natural selection, environmental factors, population densityies, plasticiity, etc. With so many theories, this article takes a look at how different variations in projeny size are influenced by evolutionary patterns
