This eagle at Mkhuze Game Reserve in KwaZulu-Natal is ruffling its feathers and looking uncharacteristically frilly, in a photo that is somewhat grainy because it was taken at quite a distance. Urban wildlife In this model, there is one activating protein that activates both itself and an inhibitory protein, that only inhibits the activator1. Both are aesthetically appealing and proportional. How Animals Got Their Spots and StripesAccording to Math Also, weathering patterns can create unusual rock formations such as The Giant's Causeway, Some patterns in nature are yet unexplained, such as, Repeating patterns in nature are diverse and are demonstrated by a repetition of a pattern in the same size or varied in composition. What is the Golden Ratio in Math? Second, the activator must diffuse more slowly than the inhibitor.

Thanks Buddy I think ladybird is the UK naming convention that we follow here, for what we should all more accurately call ladybeetles! The plants, on the other hand, are a puzzle. Such patterns are re-presented in many forms, such as in leopard skin prints and polka-dot fabrics, but here I stick with dots I spotted in their natural form. Thanks very much. I wonder if the spots are in any way hypnotizing and thereby distracting to predators, but I imagine once they spot their prey, they do not allow its spots to divert their aim. There are various types of spirals; while they look very similar, mathematically, they are only approximately close. Urban wildlife KwaZulu-Natal "We also planted the seeds in different types of substrate, including a thick coconut fiber that represents low diffusivity, since it's harder for the water to move around, and paper towels where the water can diffuse faster.". Mathematics is seen in many beautiful patterns in nature, such as in symmetry and spirals.

All your photos are stunning, in particular the one of the leopard, which shows clearly just how the colouring of his body can blend so naturally in with the vegetation. Spirals are a natural pattern produced as the organism develops or a hurricane is formed depending upon the dynamics of growth and formation. And how nice that we appreciate flowers as much as insects do! Its always a pleasure to dive into your posts because they always offer so much. Last summer Brendan D'Aquino (opens in new tab), a computer science undergrad at Northeastern University in Boston, worked with Flavio Fenton (opens in new tab), a professor of physics at Georgia Tech, in his lab as part of a summer internship to test Turing's theory. In fact our arums produce a lot of seed perhaps because of these visiting pollinators and I collect the seed to generate new plants. -- Ch-ch-ch-changes Settling in and some incidental birdwatching On living harmoniously with vervetmonkeys To pastures new Festive holiday pompons Random quirkiness in thegarden As I look out my window: Vervet monkeys at rest and play on a cool summer morning Letting nature show andtell Southern equinox after springtime Septemberrains Highlighting some of our gardenbirds A road trip, Rory the Ridgeback and his recovery Masters of disguise: Praying mantisroundup Suburban wildlife in the autumn-wintergarden Some old postcards depicting nature and theoutdoors Cabbage-trees a virtual and literal feast in thegarden Following footpaths in the centralDrakensberg African elephants, bark stripping, nutrition andtrees The African baobab: Super tree with superfruit Subtropical depression: Catastrophic flooding in KwaZulu-Natal and the EasternCape My camera and eye: Strangefascination Pets and war: Ernestos Sanctuary for Cats inSyria Take me to the river: Riverine roaming at Kruger NationalPark From tall giraffes to a ground-dwellingnightjar Summertime mountain flowers Scrutinized by buffalos at the Kruger NationalPark Abstract photos from Kruger NationalPark Three dwarf antelope: Steenbok, Sharpes grysbok andklipspringer Looking forward Zooming in: Kruger Park pics forChristmas Life in the mopane scrub and woodlands at Kruger NationalPark Companionable creatures at KrugerPark Home and away: From near tofar A family of yellowmongooses The wild Honeysuckle-tree floweringabundantly Watching spiny flower mantidsgrow An unusually confiding tambourinedove Floral treats in the springgarden Black cuckooshrike named for the unicoloured male, this is thefemale Logging on again First flowering of an Aloeferox Elephant rumbles Just saying hi! She covers several science topics from planet Earth to paleontology and archaeology to health and culture. A very intriguing series of posts too. suburban spaces The process of developing pattern formations involves two chemicals that react with each other as they diffuse through the body at a cellular level. Ill slowly read through all of them . The snake lily also known as the paintbrush lily (Scadoxus puniceus) bears spots at the base of young flower stalks in the spring. Ty distils the world around him into its basic geometry, prompting us to look at the mundane in a different way. Stripes will orient parallel to a "parameter gradient," where the activating and inhibitory properties of the two proteins are higher at one end of the tissue than the other. What are spots and stripes? - AnswersAll Repeated uniform patterns are called tessellations, where the repeated shape is adjacent to the next, as shown in the snake image below. The arum is an interesting plant and it is nice when it produces its own seed and also that it germinates quite successfully. So many details youve spotted (sorry, couldnt help myself) in your neck of the woods. Alan Turing, was famous for cracking the Enigma code during World War II. Here is another photo of the same cheetah when he came out into more open ground near the road (photographed at Mabuasehube Game Reserve, part of the Kgalagadi Transfrontier Park in Botswana). Scientists have discovered that butterfly wing patterns are due to a single gene, t.WntA, which is responsible for a dazzling array of pattern elements: size, shape, colour, and its intensity. The work here by Fenton et al on chia seed patterns is a great example toward showing that Alan Turing really did have a remarkable genius for explaining the natural world.". A logarithmic spiral, as shown below, increases the distance of each spiral logarithmically. Included in Felimormia, along with cats and hyenas are mongooses, genets, Malagasy carnivores, civets and Asiatic linsangs (I had to look them up). Alan Turing, the prolific mathematician best known for helping to break the Enigma code at Bletchley Park during the Second World War, and for writing a scientific paper that would form the basis for . I love the guineafowl, which looks like a 1950s rocker, and the eagle is quite splendid. [1] [2] The pattern arises due to Turing instability which in turn .

An editable svg version of this figure can be downloaded at: https://scholarlycommons.pacific.edu/open-images/36/. Patterns repeat in nature due to chemical interactions, laws of nature (such as natural selection), and laws of physics (such as the interaction of energy and matter). A Voronoi pattern is a mathematical configuration based on points and proximal locations to adjacent cells, as shown in the image below. Computational models predict that this type of gradient causes stripes to orient themselves perpendicular to the gradient (Figure 2)2. African wildlife Early Greek philosophers studied pattern, with Plato, Pythagoras and Empedocles attempting to explain order in nature. The Graduate School of Arts and Sciences. Without an external force, the default should be spots or a meandering labrinthine pattern, depending on the properties of the activator and inhibitor. In this case, random spots of activator can be stabilized when they are far enough away from each other. 1455 Quebec Street The martial eagle is a magnificent bird, even with his spotted bloomers!
