    Nice intro, and hello Mark !!!!

    As a start for the breeding scenario, you need to apply for acceptance from the "commitee" to be added to the members breeding directory, then you go from there, you will be able to post in this section and ask for or offer mature specimens.

    Inbreeding Depression, hmmmm this could turn out to be a VERY long thread if all who have an opinion post.
    I'll start by offering a scenario.......... an egg sac (specifically pokie or avic), in a natural environment, hatches and all the siblings end up in a colony, when this colony matures percentages say siblings will mate and this will happen generation after generation, does this fortify the interbreeding argument in captivity or does it emphasise the need to vary the bloodline.

      Excellent - thanks for that, I'll wait till my spiders mature and take things from there. As for Inbreeding depression I guess it would take a lot of data from controlled tests to work out exactly what the negative side effects would be - are there any records of parthenogenesis in spiders?

        Actually, not to my knowledge, i've only really known of it in the invert world for some species of aphids, bees (wasps (i think)) and ants.
        It seems the actual transfer of sperm needs to be implemented in arachnids (and there's endless references of females producing many egg sacs from one mating (a few posted on here))
        Read somewhere once about arachnologists in the late 1800's or early 1900's conducting reasearch on parthenogenesis in spiders using a common species (tegenaria) no conclusive proof though as i remember they used wild caught specimens. will have to see if i can find it again and post the link.

          Link for the info on parthenogenesis Mark

          http://www.biolbull.org/cgi/reprint/13/6/302
          Quite interesting for the time it was written.

          There's many more links and info if you google it, in fact a lot more than when i looked for it a fair while back anyway.

            A quick hello from me

            I read a lot of articles on here so I figured why not join.

            I have been interested in entomology since I was a kid. More recently arachnology. I acquired an orphan G. rosea a couple years ago (Jelly Belly who is now gravid…hopefully). Now I have 22 T’s that I just adore and I'm always learning and soaking up all the info I can get my hands on.

            I was recently able to play with an AGB which is definitely on my wish list. Just have to sweet talk my fiance in to it first. He’s a good guy and hopefully I’ll get a couple for my birthday…. yes I’m a tad bit spoiled…but hey at least I don’t ask for jewels and gold

                Introduction

                Hi, everyone. I've just joined (well a couple of days ago) so though I'd say hello.

                I've not really been into spiders or the such very long but a guy I work with seems pretty obsessed so after listening to him for a while decided to try out some emperors.

                I now own a B. Smithi, B. Boehmi and a salmon pink (all fairly young), some emperor scorpion adults and their offspring (one finally dropped a couple of weeks ago) along with a few feeding cultures (since I also have a few reptiles).

                Well that's it from me, hope to hear from you soon.

                            Hello all.

                            I am Tara, and have been interested in spiders, but I had a terrible fear for most of my life. But recently I have started to see them in different lights, they are kinda cute . Me and my boyfriend got our first tarantula yesterday, a b.smithi who we have called Garrett.
                            My fear seems to have melted away, and has now been replaced with fasination!

                            But this was an introduction to me, nice to meet you all and it seems very friendly around here hehe!

                            Tara
