Every specimen contains genomic data, which can be extracted from leaf tissue, environmental data, such as bioclimatic variables associated with the specimen’s georeferenced coordinates, and phenomic data, which can be measured using traditional morphometric approaches, or more recently, using computer vision-based machine learning algorithms that can extract phenotypic characters from images. Genomic data can be used to construct evolutionary trees, and phenotypic data and environmental data can be used to identify functional phenotypic traits. Here, traits such as entire versus serrated leaf margins (A), leaf shape and petiole length (B), and inflorescence architecture (C) can be advantageous in certain abiotic or biotic environments. Traits that are variable within extant species, or among extant sister species, can be used to tease apart the relative contributions of the genome and environment to shape these traits (denoted by asterisk). These key functional traits associated with recent divergences can be used to infer how phenotypic traits, the genome, and the environment interacted in more ancient divergences (denoted by hashtag). https://www.richiehodel.com/contact-me daily 0.75 2021-03-20 https://www.richiehodel.com/publications daily 0.75 2025-01-16 https://www.richiehodel.com/news daily 0.75 2021-07-14 https://images.squarespace-cdn.com/content/v1/5a90984a36099bbdddfdf1eb/1626230851930-EOGEQHIVU837FZDYBR74/series_v4.jpg News - Cherry Blossom Festival, March 2021 The Cherry Blossom Festival in DC occurs in March or April every year. I put together some images and datasets to share via the NMNH social media accounts. Here are some images from the posts. Here we see the branch of a Yoshino cherry tree (Prunus yedoensis) at the DC Tidal Basin with the Jefferson Memorial in the background. On March 19, we see that the buds have just starting growing into florets, but by March 29, the blossoms have already reached their peak (defined as >70% of Yoshino cherry blossoms open). https://images.squarespace-cdn.com/content/v1/5a90984a36099bbdddfdf1eb/1626231235781-R1JOMDLOOP9YEWGASLOV/plots_v2.jpg News - Cherry blossom data We are very fortunate to have centuries of observations made by monks and others in Kyoto, Japan dating back to the 9th century. Here, I plotted publicly available flowering data, and we can see that over the past 500 years, the full-flowering date in Kyoto has shifted earlier and earlier. The peak bloom date this year was March 26; the last time it was this early was several hundred years ago, indicating the effects of climate change. Phenology for 15th to 21st centuries was acquired and analyzed by Aono and Kazui (2008; International Journal of Climatology, 28, 905-914), and is available here: http://atmenv.envi.osakafu-u.ac.jp/aono/kyophenotemp4/ https://www.richiehodel.com/news-items daily 0.75 2023-08-08 https://images.squarespace-cdn.com/content/v1/5a90984a36099bbdddfdf1eb/e3f34cd0-7727-4472-888d-583565c6c89c/IMG_8092.jpeg Cherry Blossoms - Make it stand out The appropriately-named Charlie Brown cherry tree on the DC Tidal Basin. https://images.squarespace-cdn.com/content/v1/5a90984a36099bbdddfdf1eb/c73946f3-8108-420f-8f48-da156b411b7c/series_v4.jpg Cherry Blossoms - Make it stand out Here we see the branch of a Yoshino cherry tree (Prunus yedoensis) at the DC Tidal Basin with the Jefferson Memorial in the background.
