Helped clear up the differences for me. If this information was presented in a more captivating way, this video would have been perfect. Besides that though I liked the voice over because it had a calm, smooth pace and I could clearly hear every word that was said but maybe try to sound a little more excited about the topic next time. I liked how the video was clear and presented an easy way to understand the biological concepts. Yes, it looks like character displacement. Secondly, the beginning of the video was quite dull and could easily dissuade the viewer from continuing watch the entire thing. The rationale for character displacement stems from the competitive exclusion principle, also called Gause's Law, which contends t… In fact, the question does not even make clear that the two species are found in sympatry. Asking for help, clarification, or responding to other answers. The question was answered and I liked the fact that you included a basketball example.This kept my interest but also reinforced the idea. The shift in the trait value is called character displacement. The comparison to basketball really helps make the biological concepts more relatable despite their complexity. On one hand I have the Galapagos Finch example, which is typically used to illustrate character displacement. What is the name/type/species of this spider? So I'm just waiting for you to explain your thought process. If the trait in question lacks enough heritable variation for character displacement to occur, then outcome can instead be competitive exclusion, where the more successful species will out-compete the other to the point of elimination. 7. “Science has a simple faith, which transcends utility. If a piece of software does not specify whether it is licenced under GPL 3.0 "only" or "or-later", which variant does it "default to"? Why did mainframes have big conspicuous power-off buttons? Tying the differences between character displacement and resource partitioning to a relatable and fully understandable situation allows the viewer to better understand what is being taught.

You guys did a great job of explaining the difference between two easily confused concepts, and I liked that you really emphasized them by explaining them in multiple ways. rev 2020.11.24.38066, The best answers are voted up and rise to the top, Biology Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us, Welcome to Biology.SE. MAINTENANCE WARNING: Possible downtime early morning Dec 2/4/9 UTC (8:30PM…, “Question closed” notifications experiment results and graduation. @Bakshi please provide evidence that you tried answering this question yourself to avoid having the question closed. It was humorous (and was therefore entertaining), while still solidifying the concepts presented. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. It helped to differentiate the two concepts! Looking for a function that approximates a parabola. Can anyone identify what type of bug this is? The use of the basketball metaphor was extremely interesting and it grabbed my attention immediately. Log in to Reply. Solid work. When differences among similar species whose distributions overlap geographically are accentuated, but when don't overlap the characteristics are lost. I found that a method I was hoping to publish is already known. Use MathJax to format equations. Is it character displacement (highlight on a few missing information)? I really enjoyed the the metaphors that you guys employed. I enjoyed this video because it linked an abstract concept of biology to a real world example. This competition-driven process assumes that individuals of species who overlap in their niche (and this being directly related to the degree of competition) will have lowered fitness, causing directional selection. Can anyone tell me what type of worm this is? I really liked how clear the video was and the creative use of basketball in order to further explain your concept. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. By examining how and why resources are allocated in a particular niche, scientists can better understand the complex … I do suggest something other than long definitions on PowerPoint slides in the beginning. I think that the first part of the video, before the basketball metaphor was the best part. I would suggest trying to simplify the visuals at the beginning, maybe just spacing them out in order to make it easier on the eye. Species will then evolve … This pattern results from evolutionary change driven by biological competition among species for a limited resource (e.g. Resource partitioning is the division of limited resources by species to help avoid competition in an ecological niche. However, the video was unnecessarily longer because the the “speed”, “passing” and “blocking” parts could have reduced the length and shorter videos are always better.

One thing that could have been improved was that the information in the beginning was presented in a dull manner. My answer is ready, however we have a policy of not answer homework question (or homework-like question) without the OP showing an attempt at answering his/her own question. How do I legally resign in Germany when no one is at the office? Dirac Notation and Coordinate transformation of a function. Sorry, your blog cannot share posts by email. It is no homework. You can click on, Edited. What is this part which is mounted on the wing of Embraer ERJ-145? The information in the beginning was very concise and clear. Explain. food).

My only suggestion for this video would be a better first half. So, yes if two species evolve to prey at different time of the day to avoid competition, then they have evolved so as to reduce the overlap between their ecological niche and we can call that character displacement. Biology Stack Exchange is a question and answer site for biology researchers, academics, and students. ANS) Indirect: In the case of character displacement, it is observable that the traits have changed in one way or another, and using Darwin’s theory of survival of the fittest, it is safe to assume that competition is responsible for the changes. This video was really helpful and cleared up a lot of confusion! The initial information presented at the beginning of the video would have been more interesting if you had written out the information or showed it in a more interesting way than a stationary PowerPoint slide. I might also add transitions between clips. If I stumbled upon this on the internet, I would probably click away before the video got to the more interesting half. In any environment, organisms compete for limited resources, so organisms and different species have to find ways to coexist with one another. Thanks for contributing an answer to Biology Stack Exchange! The character being displaced in a 'character displacement' scenario can be behavioural. Character displacement is an evolutionary adaptation in a heritable trait, caused by resource partitioning. Character displacement stems from the competitive exclusion principle, saying that in order for species to exist, their It is indeed the type of consequences brought about by character displacement. Is whatever I see on the Internet temporarily present in the RAM? Making statements based on opinion; back them up with references or personal experience. It is possible that divergence in their feeding time happened long before being found in sympatry. The only recommendation I have would be to create the beginning half of the video to be more dynamic to interact with the audience more.
