  1. Hey all! Some of you know me from the discord server the 'writers guild' and my frankly unsettling escapades there, others are unfamiliar with me and my talents. Here, I hope to take requests from people who need plants and animals and monsters and humanoids to populate their various worlds, and hopefully also have fun discussions with people who come here to talk about their creations. I'll give and ask for advice, and hopefully we all can enjoy or have with this thing. I hope it goes somewhere, but that's up to you all. I also hope that this keeps on going when I eventually have to shift my attention elsewhere, so... I hope you all enjoy it. Let's try to make this something interesting, alright? @Sherlock Holmes @AonEne @bees? @Blessing of Potency

    Has anybody thought about the ecology of Roshar? I notice we have a number of new species . From chasm fiends , axehounds, chull, great shells of the Reshin, and even the Rashadium. I notice the lack of avians, bears,great cats, etc of course but that’s not what interest me. In real life we have 5 creatures we can’t live without earthworms , ants , plankton, bats and lastly bees. All play a part In fertilizing the ground , to increasing the yeald of plantlife, to spreading air and spreading seeds. Without these creatures human beings would die off. The ecology of Roshar seems to revolve. Around Gemhearts. How I can’t seem to workout. Just think about it , what do the Parshendi need with gemhearts ? They don’t sell them, they don’t need them stormlight because they haven’t been Radiants . The only use I can see is a type of lantern. But they sure fought the Alethi for them . what creatures would cause life on Roshar to end if they were not present ? Therre is not much plant life described yet other than Rockbuds. The strange grass that can move and hide under the ground. Like what is the constant that life on Roshar ? Using our blueprint earth , water, plants, air , carbon monoxide . Do we have enough to posit what Roshar system is ? I’m interested to hear what @Calderis and @RShara and some of you other sages have to say ? I hope u find this as interesting as I do !
  3. I apologize if this has been proposed before (my searches didn't find it), but I think that Shinovar is the last remnant of Roshar's original, Earthlike ecology. My theory is as follows: Once, the Rosharan super-continent was Earthlike, with Shinovar at its eastern end. Then Odium sent the Everstorms, which began to erode the western part of the continent. In response, Honor sent the Highstorms, which laid down crem, creating new lands to the east. Over the course of the millennia, the original continent was eroded away up to Shinovar, while a new continent was created. Meanwhile, sea creatures began to migrate onto the new land (possibly with help from Honor or Cultivation) and, with the help of magic, evolved into chulls, axehounds, skyeels, and the rest. Now Shinovar is all that remains of the planet's original ecology. In addition to geology and the storms, this theory is supported by the fact that most of the non-Shinovaran wildlife of Roshar does not seem physically possible without the help of magic. In real life, a large land invertebrate like a chull would be crushed by the weight of its own exoskeleton, even in a lower-gravity environment like Roshar's (remember the square-cube law). Brandon has confirmed that chasmfiends require spren to survive, and I suspect that something similar is going on with the more mundane greatshells. Thus, these life forms must postdate all of the ambient magic that currently exists on Roshar. Moreover, there's Hoid's comment about the orphaned etymology in the term "axehound", which seems to imply that hounds once existed on Roshar but have been forgotten.
  4. Hi all. Several people have already noted that the existence of chull and other large arthropods requires Roshar to have more atmospheric oxygen than Earth does (if you want to brush up on arthropod respiration, start here: http://rspb.royalsocietypublishing.org/content/early/2010/03/04/rspb.2010.0001). However, it seems to me that Roshar's flora imposes additional atmospheric constraints. I have a theory which explains the following anomalies: 1: Rockbuds could not possibly be productive enough to support an ecosystem and a civilisation. 2: If crem is fertilizer, stormward waterbodies like Longbrow's Straits and the Steamwater ocean should have massive nitrogen and phosphate pollution, and should therefore be solid masses of algae. But Shallan's journey over Longbrow's Straits shows that this is not the case. 3: The atmosphere on the Horneater Peaks is different from, and healthier than, the atmosphere at lower elevations ("airsick lowlanders"). However, although temperatures on the peaks are similar to temperatures in the lowlands, agricultural productivity must be much lower--almost the entire population is devoted to food production, and the Horneaters are nevertheless still defined by having to eat parts of animals which other cultures shun. My solution to these problems is that Cultivation drains the Progression surge from the stormward waterbodies, and channels that Progression into terrestrial plants. Meanwhile, Honor (or, after his Shattering, some combination of his splinters and slivers) uses some combination of Adhesion (in its atmospheric pressure sense) and Gravitation to pull both oxygen and carbon dioxide towards sealevel. Thus, airsick lowlanders are suffering from both hyperoxia (too much oxygen, causing impired vision and seizures) and hypercapnia (too much carbon dioxide, causing a whole laundrylist of symptoms, including mental impairment (certainly the most common cause of the "airsick" comment) and irritability (contributing to their warlike culture)). A more detailed description is below. .......... First, photosynthesis on Roshar must be more efficient than it is on earth. Why? Well, it is obviously problematic that rockbuds and similar plants support the dietary needs of a reasonably densely populated nation like Alethkar. Rockbuds have to support their own relatively high metabolism (all that movement would mean that they would have to be at least as metabolically active as a sea urchin), and they produce energetically-expensive structures like shells. The drawings show that they have a relatively small leaf area to support all this. Obviously, some of these metbolic needs are met by crem, which seems to act as NPK fertilizer, but even massive fertilisation would only barely allow rockbuds to break even, much less support an ecosystem and a civilisation. How do I know? Well, let's use respiration as a proxy for metabolism. Each day, a sea urchin respires between 15 and 25 mmol O2 per gram dryweight (https://books.google.com/books?id=B322HrCUvNEC&pg=PA54&lpg=PA54&dq=sea+urchin+metabolism+calories page 51). Meanwhile, on earth, a perfectly fertilized leaf under perfect conditions produces at most 40 micromoles O2 per second per square meter (http://www.saps.org.uk/saps-associates/browse-q-and-a/463-how-much-oxygen-does-a-houseplant-give-off-in-a-day ). Perform the necessary conversions, and we see that one gram drywieght of sea urchin would require 60 square centimeters of leaf to break even metabolically. Again, on earth, it would take absolutely ideal conditions for a rockbud to be able to support itself, much less grow. So, either rockbuds have access to more energy than earth-plants do, or they have access to more carbon dioxide, or both. First, energy. Maybe Roshar's sun is much brighter than Earth's. However, I've not seen any evidence of this, and skin cancer is never mentioned--it seems like skin cancer would be the chief cause of death on Roshar if this were the solution. So, maybe rockbuds use a more efficient pigment for photosynthesis than chlorophyll. But nope: When Shallan had her shipboard vision of her garden, her first impression was greenness, so we know that Roshar plants reflect green light just like earth-plants do, and thus almost certainly use chlorophyll. So if Roshar plants are getting extra energy, they're not getting it directly from their sun. However, one of Roshars two-and-a-half deities is Cultivation, who is closely linked to the Progression surge, which is closely tied to plant growth. Meanwhile, there are the Stormward oceans, which are well-fertilized with crem but strangely non-fertile. It makes sense that Cultivation is channelling Progression out of the oceans and onto land. This might or might not be sufficient to explain rockbud productivity, but it leaves Honor out of the loop, and it doesn't explain starving Horneaters and airsick lowlanders. So, we give half the burden to Honor. Let's assume Roshar's original atmosphere was similar to earth's: 80% nitrogen, 18% oxygen, 300 parts per million carbon dioxide. Honor uses Adhesion and/or Gravitation to Bind both oxygen and carbon dioxide downward. The upper atmosphere is now almost entirely nitrogen, the Horneater Peaks are still similar to Earth, and sealevel is something like 40% oxygen and a full 5 percent carbon dioxide, enough to induce symptoms. Chulls frolic in the high-oxygen environment, plants have much more CO2 to work with, and lowlanders get airsick. Meanwhile, without the elevated CO2 concentrations, agriculture on the Horneater Peaks suffers. This unnatural distribution of gasses might cause Roshar to appear to have an entirely-nitrogen atmosphere from a distance, explaining WoB that astronomers wouldn't think Roshar is habitable. Of course, this theory is significantly weakened if there are superlarge arthropods on the horneater peaks--I think I remember Rock talking about eating Chull heads, but I don't remember if he ever said if Unkalaki chull were as large as lowland chull, or if they were much smaller. Lemme know whacha think. Much respect to all y'all from this first-timer, ecohansen
  5. I recently read a quote from Brandon mentioning that the hunting on the Shattered Palins would have a serious ecological impact and that we should expect to see signs of this soon. I'm expecting to see at least the start of the impact in the next book. What do you think? So what do we know about Chasm Fiends? Chasm Fiends are massive, they're predatory, and they're carnivorous. We should also assume that they are active hunters since the Bridge Crews had no knowledge of safe times to scavenge, nor do we have any indication that the Alethi high command had such knowledge. We know they ate goats, chulls, and people during the hunt, but what do they eat the rest of the time? I'm of the opinion that we are about to see the regular Chasm Fiend diet consisted of something omnivorous that finds people tasty. That the population of this critter has exploded due to lack of hunting, and that both the Parshendi and the Alethi will soon begin to encounter these critters regularly as these critters spread westward through the canyons. I think these critters may be why the Parshendi can't retreat to the east. I could be totally wrong about how this over hunting will impact the area, so lets hear some other theories if you have them, or reasons why mine is a good or bad one. Edit: I'm directionally challenged
