Sperm Competition

May 18, 2010 by J.B.

If you watched the video from the previous blog post, you may have some questions about a certain part of the male chimpanzee anatomy. Think of this post as Everything You Wanted to Know About Chimp Testicles, But Were Afraid to Ask.

Burrito is not unique – male chimpanzees have rather large testicles compared to other apes. And there’s a very interesting explanation for this. Most people are familiar with the concept of males competing for access to females. For example, male gorillas will compete for control over a harem of females – whoever controls the harem has primary mating access. But female chimpanzees will regularly mate with multiple males during estrus (see this recent article for an interesting take on chimp mating behavior). Therefore, much of the competition between males takes place between their sperm within the female’s reproductive tract.

If you think of mating as a lottery, with the prize being a fertilized egg, then whoever can produce the most sperm is essentially buying the most lottery tickets. And whoever has more tickets has a better chance of winning. There are also other forms of sperm competition besides this sperm “arms race”. Chimpanzees also produce sperm plugs (also called copulatory plugs). After mating, some of the semen will coagulate to plug up the cervix, so that sperm from future mating (with other males) will be less likely to reach the egg.

So for chimpanzees, it pays to produce a lot of semen, and that requires large testicles. Now you know!

Who’s Burrito’s biggest fan?

May 18, 2010 by Diana

Tamela is looking for Burrito’s biggest fan to buy a one-of -a-kind handmade Burrito belt buckle (see photo below).

She also has very cool paperweights for sale in her online Etsy shop with interchangeable photos of the Cle Elum Seven, so you can spend each day with a different chimpanzee image!

For other fun stuff to support the chimps:

Cindy still has some of her adorable beaded bracelets available in her Etsy shop – get your Burrito, Negra, Missy, Foxie, Annie, Jody or Jamie bracelet today!

and don’t forget about Jeani’s Firstgiving page with the woodburned pins as a thank you for your donation

and Margaret Parkinson’s Firstgiving page with a card with a print of one of her amazing paintings as a thank you for a donation

And Pam Lehnert’s Firstgiving page and offer to transform your space for a donation to the sanctuary.

After Pam worked her magic

So many fun ways to support the chimps for our 2nd Anniversary Fundraising drive! Thank you, everyone, for your hard work and great ideas and for those who have supported these supporters!

2nd goal reached!

May 18, 2010 by Diana

Thanks, Barb in Ohio for making the pledge to cover the remaining $873 we had to go to reach our second fundraising goal! As of this morning (thanks, in part, to a generous check from Kat Morrell and to Tamela’s continued success with her Etsy store), we’re up to $40,476 raised! So close to our ultimate goal and three cages windows replaced with glass!!
