Hey there, we are in the same evo class. I just wanted to try out this talk thing. -David(sluology) Sluology (talk) 03:13, 30 August 2015 (UTC)

Hello, Cbiology, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.
I hope you enjoy editing here. If you haven't already done so, please complete the student training, which introduces you to editing and Wikipedia's core principles.

References: Sexual Dimorphism in spider Nephila species
You should move these to the talk page of the study species so that more users will come across them and can comment on them! Also, you might consider diversifying your authors: Elgar is on 3 of the 4. Might there be a popsci article on spider size dimorphism that is useful?
Below are my references to the sexual dimorphism in the spider Nephila species along with my own comments on the articles. Feel free to comment!

I found several citations which help link the sexual dimorphism in spiders to several tested possibilities. There seems to be some disagreement in the scientific community in the cause of the difference in size of males and females, with females being smaller. The Journal of Arachnology article titled "Nephila Female Gigantism Attained through Post-maturity Molting." gave evidence for the Nephila pilipes that the large size difference was significantly affected by the female spiders continued molting after maturity which increased there carapaces, outer shell, size. While Nephila plumipes Latreille spider study in the Behavioral Ecology article "Sexual Cannibalism, Competition, and Size Dimorphism in the Orb-weaving Spider” explained the sexual dimorphism as a product of two competing selections, one that smaller males are preferred by females as they are less likely to be cannibalized but, that when males compete between each other the larger males win. Other evidence of the species sexual dimorphism comes from the Frontiers in Ecology and Evolution article which explained through an examination of the species as a whole that the size selection for both males and females is moving toward larger animals but, that the rate of male spider growth is less than that of female spiders. Then the article from Evolutionary Ecology also supported the idea that there are different forces acting on the selection of males which males reproductive success favor larger and smaller spiders in different ways whereas females reproductive success was greater when they are larger not smaller. These articles are all a starting point for further examination of what are the key factors influencing sexual dimorphism in the golden orb weaver.
