Home | Leafsnap: An Electronic Field Guide Plantifier on the App Store Massive Database of 182,000 Leaves Is Helping Predict Plant Family Trees The story of a plant is etched in its leaves. A tree growing in a cold environment with plenty of water is more likely to have large leaves with many serrated teeth around the edges. But if the same species lives in a warm, dry region, its leaves are likely to be smaller and smoother. Now, an atlas that traces the shapes of 182,000 leaves from 141 plant families and 75 locations around the world shows promise for refining scientists’ ability to read that story. Using that atlas, researchers found that leaf shape alone accurately predicted where a leaf was collected 14.5% of the time, and plant family correctly 27.3% of the time. Researchers hope that the approach will help them to learn more about the forces that shape plant leaves, and even to get a glimpse of ancient climates by analysing the shapes of fossilized plants. The results were posted on June 20 to bioRxiv, a server that hosts biology preprints. Shaping up the data Leaf by leaf “Morphology is being reborn,” Städler says.
Google is the best plant ID app and it will only get better | Jack Wallington Garden Design, Clapham in London There’s been lots of hype about plant ID apps and having tried most of them I’ve never been impressed. However, my school friend David who now lives in LA and works for Google pointed out earlier in the year how accurate its reverse image search, or Google Lens as it is now called, has become. Download the Google app now to give it a whirl, the world’s collective knowledge of plants and other wildlife is about to get much, much better. Everyone I’ve subsequently told about it has been blown away. Here’s how Google Lens works 1) load it up and press the image icon 2) take a photo or select one from your phone 3) Search for matches Google will then use patterns and colours in the photo to conduct a search online for matching images. 4) scroll down if it’s not there Sometimes it’s close but the correct species isn’t there, but it’s usually almost there and the correct species may be further down. Give it a try and see what you think. The following two tabs change content below.
The best apps to identify unknown plants and flowers | The Telegraph PlantNet Plant Identification Virginia Tech Tree Identification brings the award winning Virginia Tech digital dendrology material to your Android smart phone. It contains fact sheets for 969 woody plants from all over North America with an in depth description, range map and thousands of color images of leaves, flowers, fruit, twigs, bark and form. Users can narrow the species list for any location in North America using the phone's GPS, network signal or any entered address or zip code. NOTESThe 650 MB database of tree photographs and text is downloaded from our server. Text and photography by John R.
Plant Architecture and Its Evolutionary Implications — In Defense of Plants Another interesting finding borne from these models is that there doesn't seem to be strong correlations between architecture and phylogeny. Although species within a specific genus often share similar architecture, there are plenty of exceptions. What's more, the same form can occur in unrelated species. So, at this point the question of what is governing these models becomes apparent. Although many scientists have attempted to tackle these sorts of questions, I want to highlight the work of one individual in particular - Dr. 1) Plants have to capture sunlight and avoid shading their own leaves. 2) Plants have to support themselves structurally. 3) Plants have to conduct water to their various tissues. 4) Plants must be able to reproduce effectively. Using these basic constraints, Dr.
PlantSnapp: plant identification, flower.s and garden.ing tip.s svt – Jo, faktiskt. Och det är ju för att näckrosen är en väldigt gammal blomväxt. Den är en systergrupp till ”urmodern” tror man, säger Vivi Vajda, professor i paleontologi och geolog vid Naturhistoriska riksmuseet. Nära släkt med näckrosen Genom att jämföra i stort sett alla ordningar och familjer av blommor som lever idag, hela 792 arter, har forskare från 14 länder tagit fram en modell på hur de tror att den allra första blomman såg ut. Det är den största jämförande studien som någonsin gjorts på blommor och resultatet: ”blom-urmodern”, presenteras i Nature Communications i dag. – Det man har kommit fram till är att den är tvåkönad, alltså ståndare och pistiller i samma blomma. Forskargruppen går varken in på blommans färg eller storlek – den kan alltså lika gärna ha varit färgglad. Kan den ha levt i vatten precis som näckrosor? – Ja, definitivt. Drömmen – att hitta ett fossil
Plant blindness in smartphone identification applications – are we passing on our biases to our helpful apps? It is well-known that people are better at identifying animals than plants and this relative inability of people to identify plants is increasingly termed “plant blindness”. Recent research has identified links between undervaluing nature, mental health, and plant blindness. Ask anyone to identify common animals and most will easily identify badgers, foxes, blackbirds and otters. But ask the same people (assuming you have not asked a botanist in the first place) to identify rowan, lords & ladies, horse chestnuts or wood anemone and most will be stumped. There are many useful guides to help the more nature-minded of us to identify common species (and less common) but it is the advent of smartphones (a computer in almost every pocket) that perhaps holds the most promise for helping people over-come plant blindness. There are now an abundance of applications that are targeted at identifying plants and animals. References Adams, R. (2019). Pearson, DG. & Craig, T. (2014) The great outdoors?
AMKK（東 信、花樹研究所） Botanical Animation “Story of Flowers” Produced by AMKK Directed by Azuma Makoto Illustration by Katie Scott Animation by James Paulley < ABOUT > This “Botanical Animation” is an independent art project from AMKK, who create various works of art using flowers and plants. The animation was developed for kids to show the life cycle of flowers. Azuma made the original story and requested London-based illustrator and animator Katie and James breathe life into the animation with their beautiful work. < STORY > Many different flowers are growing beautifully and strongly in this world.
