Such a hiatus!
I really underestimated how much work two jobs would be. Of course, as with all things, there are busy and quiet times, but when both jobs hit the busy period it gets quite busy indeed. Fortunately, both jobs were contract work, and have now ended, and so I now find myself employed more in line with my proclivities – that is to say – surfing.
I wrote a little while ago about ticks, specifically the the holocyclus species that we have locally. Ticks are the perfect example of a zoonotic clusterfuck – they perfectly illustrate the hubris of modern medical science. Ticks give people diseases in curious, non linear ways, with often ill defined pathologies and vastly different levels of severity. Oh, and some people, like myself, are naturally, genetically immune. The dullards amongst us might suggest that this is something that can be mapped onto my particular ethnicity or bloodgroup, but in the age of ‘identifying’ as various things that one is quite evidently not, I have concluded that the most logical explanation for immunity to alpha-gal allergy and disease is that I am three parts bandicoot.
Bandicoots live here, they are a stalwart of coastal NSW. Bandicoots are common and also, helpfully, really really cute. They have long prehensile noses that they use for spreading diseases around corners. The funny thing is – you never see them. They’re nocturnal, so that doesn’t help, but there are plenty of nocturnal Australian animals that you see all the time, everything from possums to those gamers with those pale, vestigial legs. Unlike the gamers, bandicoots spend a lot of their lives snuffling around in the leaf litter getting things done.
I’ve only seen them a couple of times, but I know there’s heaps of them. Bandicoots are absolutely essential to the life cycle of the paralysis tick. Without bandicoots there would be almost no ticks at all. Yes, ticks live on all sorts of animals, but bandicoots provide the nursery for the ticks. Without them, the numbers drop precipitously. Bandicoots are the only animal that is completely immune to the tick venom -they can literally carry thousands of ticks with no ill effect. And, as I said, they like to hang around in the leaf litter, which is an excellent place to acquire four million of your closest friends.
Ticks also like it wet – their eggs and larvae are prone to drying out. Indeed, the only truly effective treatment for tick control is diatomaceous earth – it essentially glues up with the eggs and, to a lesser extent, the larvae, and they dry out. When it’s wet there are more ticks. Usually, winter is a quiet time for ticks locally because our winters are pretty dry but the last two winters have been very wet, and the ticks have been on a rampage.
Currently, we haven’t had any decent rain for about a month – we appear to have returned to a more typical weather pattern, where the winter days are sunny and dry and reasonably warm. I would have expected the tick numbers to drop away to almost nothing however, that’s not the case. The ticks are going crazy this winter.
For the last six months or a couple of local government bodies have been shooting foxes. Foxes eat bandicoots. You can see where this is going. Indeed, there is such a boom in the bandicoot population that areas of suburbia look like they’ve been shelled by the world’s cutest and most poorly organised military (bandicoots leave little holes surrounded by a mound of dirt). Naturally, Australian suburbia has little time for Lawn Assaults, and so the level of consternation is high.
What’s really fascinating though is that there is so little research and information about ticks in south eastern Australia. We know how the mechanisms by which they fuck humans up, but we know surprisingly little about their life cycle and numbers – their ecology. Aside from the statement that bandicoots are important to the life cycle of the ticks, there’s almost nothing that gives any idea of how important. Now, as the bandicoot numbers explode, we’re getting a sense of the impact on tick numbers.
An example – I was talking to a landholder last week who did a cool burn years ago through a patch of Red Gum forest on his property. What returned, after the burn, was a monocrop of needle grass – basically, sharp pointy grass that foxes don’t like. So, the bandicoots were most impressed with the new digs and moved in in their thousands, and the tick numbers increased dramatically.
The importance bandicoots also helps answer some of the weirdest aspects of ticks – why are there so many in some places, but none nearby? I think it’s got something to do with how suitable the habitat is for bandicoots. Are there dogs around? Is the leaf littler thick enough? Bandicoots are also territorial, so there is an upward limit on how many one might find in an area, but that number is high.
I suppose what I’m most fascinated by is the lack of knowledge about the ecology of ticks. We live in an area where ticks regularly sicken humans and kill dogs (and other mammals) and we really don’t know that much about them.
