Have Gunbunnies Met Their Match? Zoology Update.



The BBC are reporting today on a particularly rare creature, the Hispaniolan solenodon, which has as its main distinguishing characteristic that it is a venomous mammal.

The astute readership of this journal has likely already noted the lack of solenodon Tiny or Anthropomorphic avatars available. Most likely this is due to the obscurity of these animals, and not their unique rat-vs-shrew looks, or certainly, their ability (rare in Mammalia) to inject venom during a biting attack.
Another peculiar (and one might rightly say, disturbing) feature of the solenodon is that the young stay close to their mother by "hanging on to her elongated teats", as one article states. Of note, these teats are located near the buttocks of the creature, an arrangement that may make one glad not to be a juvenile solenodon.

They also have odoriferous glands in the groin and armpits which are reported to give off a goat-like smell. These particular traits may explain the lack of widespread interest in solenodon anthropomorphic roleplay, at least in most social circles.

Normally solitary, solenodons only seek out their own for mating, after which they retreat from one another.

They are said to be easily-provoked, biting and squealing upon the slightest stimulus. However, when they sense they are being pursued as prey, their behaviour tends towards remaining motionless, and hiding the head -- not a particularly advantageous adaptation, which perhaps explains their endangered status.


So, perhaps, the initial thought that this venomous mammal would be a reasonable match against the Caledonian gunbunny was off-base. Granted, the solenodons have the advantage in the venom category, and they are ferocious in their own right. However, L. caledoniensis takes the lead in indefatigability, panache, derring-do, and loyalty.

Salinity Data for Caledonian Waterways.

A conversation on Caledon state chat yesterday raised the question of whether a certain body of water in Caledon was fresh, brackish, or seawater.

Fortunately, a prior field expedition which surveyed waterways around the Independent State had also collected surface salinity data. These results had been unpublished (and not updated after recent cataclysmic tectonic activity), but seeing as how at least one of our citizens would find the information useful, I exercised my editorial powers to publish the data without their as-yet-unfinished analysis.

This illustration shows the surface salinity in parts-per-thousand, mapped on a spectrum from green (fresh water) to blue (sea water). Brackish water is defined as having a salt concentration of 0.5 to 30 parts per thousand.*

A cursory view shows that the Independent State is fresh-water replete in areas with higher elevation. The Firth tends toward mild brackishness towards the east, and more pronounced to the west and the open sea. Lower-lying areas show a more-rapid increase in salinity as a function of distance from shore.

Limitations of these results include a lack of sampling at depth, no correction for water temperature, and a lack of readings across time (meaning that any diurnal or seasonal variations are unknown. The Winterfallen waters north of Caledon remain unstudied.

Readers wishing some advice on which fish ought to be introduced to a nearby stream, which plants may flourish at a given location, or simply where to refill one's canteen may find this map useful.

Regrettably, a lack of grant funding current prevents further data collection or analysis, at least at present.

* The actual phenomenon being measured is not salinity but rather halinity, a measure of the halide content of water. This should not be confused with conductivity (measuring the ionic content of water), or turbidity (measuring the particulate matter content), though each of these measurements overlap to some degree.

Oceanography update: Rough Sex at 40k Leagues Under the Sea



From Scientific American, an article regarding the mating habits of squid that makes one glad to be a mammal:

"What do you do to pass on your genes to the next generation if you are really hard up, it’s too dark to see clearly and you are literally under enormous pressure? The short answer: play rough and weird."

To cross over into anthropology for a moment, I would venture to say that "rough and wierd" may describe a fair amount of activity in SL. Just an educated guess, that is.

Public Health update: Papal mortality and Welsh rugby

The most recent issue of the British Medical Journal, the Christmas edition, continues the tradition of prior years in reporting on the truth (or lack thereof) in popular medical knowledge.

Here is a sample of one of the medical myths put to the test:

Payne GC, Payne RE, Farewell DM. Rugby (the religion of Wales) and its influence on the Catholic church: should Pope Benedict XVI be worried? BMJ 2008;337:a2768. doi:10.1136/bmj.a2768


Objective: To explore the perceived wisdom that papal mortality is related to the success of the Welsh rugby union team.

Design: Retrospective observational study of historical Vatican and sporting data.

Main outcome measure: Papal deaths between 1883 and the present day.

Results: There is no evidence of a link between papal deaths and any home nation grand slams (when one nation succeeds in beating all other competing teams in every match). There was, however, weak statistical evidence to support an association between Welsh performance and the number of papal deaths.

Conclusion: Given the dominant Welsh performances of 2008, the Vatican medical team should take special care of the pontiff this Christmas.


A link to the editorial covering all the myth-busting articles can be found here:

Archæology: top ten discoveries of 2008.

Archaeology Magazine has again given us their list of the top ten archaeologic discoveries of the year.

The year is not quite exhausted, however, leaving enough hope that one may still yet unearth something truly wonderful in the waning days of December.

However, I am certain that this one find (mentioned tangentially in the above top 10 list), will be hard to top:

Gilbert TP et al. DNA from Pre-Clovis Human Coprolites in Oregon, North America. Science 2008; 320 (5877): 786-789. DOI: 10.1126/science.1154116
http://www.scienceonline.org/cgi/content/abstract/320/5877/786


The interested reader may search for the images of the artefacts via the usual routes; I have a strict no-fæces-images rule for this site.

And if one of my readers does come upon something to challenge the abovementioned top ten discoveries, or even the coprolites, please forward the details straightaway. You may use your judgement in forwarding actual samples.

A great day, comrades: we sim into history.

As I was subject to a fair amount of unclaimed time this weekend, I took on a new project: running an OpenSimulator environment at home.

Using a somewhat-recent personal computer running Windows (a choice of necessity, not preference, I assure you), I successfully installed and configured diverse and arcane files.

Then, using the better parts of my talents (the creative ones, as opposed to technical), I designed and placed 4 sims on my grid.

Photographic proof is as follows:

Fig. 1: in which I tolerate the Windows interface.


Fig. 2: in which I claim these sims in the name of Caledon, ex patria.


The fact that I can log in to my grid from my laptop and play with 4 sims, each with 45000 available prims, is awesome, as in full-of-awe. (Compare the Russian word грозныи, grozny.)

The area is desolate, though, and bereft of state channel chatter, or any friends visiting -- a definite shortcoming.

A full discussion of materials and methods for this experiment will be available upon request.

A Summary of Effects of Recent Changes by Linden Lab.

Linden Lab, unaware that they are actually an entertainment provider, successfully decreased the entertainment value of their product, simultaneously increasing customer ill-will towards them.

To prove this, I have the statistics and p-values and references &c. laying around here somewhere ... but suddenly, I just don't feel like writing.
