Who Would've Imagined a Lowly Sea Slug Boasting a Radiant Color Who would’ve imagined a lowly sea slug boasting a radiant color, beautiful name and solar- power? I present him to you, Constant Reader, in this month’s CTR message. Imagine if, after eating spinach, your skin cells glowed green. This guy accomplishes the task as a way to store energy to last during lean times. Part animal yet part plant due to chloroplasts actually incorporated into his chromosomes, the EEE is only about half the length of a crayon, and lives along the eastern U.S. coast. Instead of slugging it out with traffic all alone, Commute Trip Reduction (CTR) methods are here for you: o Carpool or vanpool. Sluggish traffic will NOT get you down, oh no. You’ll learn which departments do what, how do they do it, what it’s like to work there, and you might become green with envy because you’d like to work there. o Ride the Intercity bus. You’ll positively glow when you ride the roads for FREE just by showing your County ID. Yes, Virginia (and all County employees by any other name,) there IS a completely free commute for you. o Ride a human-powered bicycle or walk to work if you live close enough. Choose the greenest CTR method and get fit, in the bargain. o Plop & Ride by riding your bike to a bus stop, plop it on the bus front then take the bus to work (for free!) See the previous two items. o Adjusted work week (4-10’s, 8-9’s, etc.) or Telecommute if your department allows. Who wouldn’t want to (chloro)plast-er themselves to the sofa an extra day or two of the week? Check with department management regarding availability of this alternate commute option. If you commuted by any means other than driving alone at least twice in October, you could be one of four winners of a prize almost as valuable as emeralds. Check ‘em out: a stylish reusable grocery bag, magnetic fridge list, or Rubbermaid storage container.

Eastern Emerald Elysia (Elysia chlorotica) Elysia chlorotica P\photo by EOL Learning & Education Group Elysia chlorotica is a medium-sized green sea slug of the Plakobranchidae family. Elysia chlorotica is a partially solar-powered slug that sequesters and retains active chloroplasts from the Vaucheria litorea algae it eats. During the feeding process, it first punctures the algal cell wall with its radula. The slug then holds the algae firmly in its mouth and, sucks out the contents. Instead of digesting the entire cell it retains the algal chloroplasts, by storing them within its own cells throughout its digestive system. The incorporation of chloroplasts within the cells of the slug allows it to capture energy directly from light, like most plants do, through photosynthesis. In periods where algae is not readily available as a food supply, the species may be able to survive for months on the sugars produced through the photosynthesis done by the incorporated chloroplasts. Thank you to http://www.dailymail.co.uk/sciencetech/article-2939249/The-solar-powered-SLUG- Creature-steals-genes-algae-eats-photosynthesise-like-leaf.html#ixzz501eXIjz1 The solar-powered slug steals genes from the algae it eats to photosynthesize like a leaf Biologists found Elysia chlorotica has hijacked a gene from green algae The slug lives in shallow waters off the east coast of the United States It uses the gene to maintain chloroplasts it steals from the algae it eats The slug uses the chloroplasts to create nutrients from the sun's energy Scientists want to understand how the slug is able to use plant genes They believe it could help to develop new treatments for genetic diseases A bright green sea slug has been found to have stolen genes from the algae it eats so that it can produce energy from sunlight just like plants. The slug, called the eastern emerald elysia or Elysia chlorotica, has incorporated genes from algae into its own chromosomes enabling it to photosynthesis. This process essentially allows the slug to become solar powered, using the sun's energy to turn carbon dioxide and water into the nutrients it needs to survive. Researchers behind the discovery believe it may be possible to use this form of genetic hijacking between species to create new types of medical treatment for genetic diseases in humans. Professor Sidney Pierce, a biologist at the University of South Florida and the University of Maryland, said: 'There is no way on earth that genes from an alga should work inside an animal cell, and yet here, they do. 'They allow the animal to rely on sunshine for its nutrition, so if something happens to their food source, they have a way of not starving to death until they find more algae to eat. 'Figuring out the mechanism of this naturally occurring gene transfer could be extremely instructive for future medical applications.' If it is possible to understand how the slug manages to use these plant genes may allow new types of genes from other species to be used to treat human diseases. Elysia chlorotica is found in shallow pools and salt marshes along the east coast of the United States, particularly in Massachusetts, Connecticut, New York, New Jersey, Maryland, Florida and Texas Juveniles are usually a reddish-brown colour before they begin feeding on algae. It has been known since the 1970s that the Elysia chlorotica is able to incorporate chloroplasts from algae into its own cells, turning them bright green. Chloroplasts are tiny capsules of biological machinery, or organelles, inside green leaves that use sunlight to power chemical reactions that plants need to survive. The slug sucks the sap out of the algae Vaucheria litorea and embeds into the cells of its digestive system, and is then able to use these chloroplasts to produce carbohydrates and lipids for itself for up to nine months. .

Abstract Background: Among metazoans, retention of functional diet-derived chloroplasts (kleptoplasty) is known only from the sea slug taxon Sacoglossa (Gastropoda: Opisthobranchia). Intracellular maintenance of plastids in the slug's digestive epithelium has long attracted interest given its implications for understanding the evolution of endosymbiosis. However, photosynthetic ability varies widely among sacoglossans; some species have no plastid retention while others survive for months solely on photosynthesis. We present a molecular phylogenetic hypothesis for the Sacoglossa and a survey of kleptoplasty from representatives of all major clades. We sought to quantify variation in photosynthetic ability among lineages, identify phylogenetic origins of plastid retention, and assess whether kleptoplasty was a key character in the radiation of the Sacoglossa.

This study was carried out, through a total of 271 scuba dives, from 2017 to the beginning of 2020 in four sites located along the Ionian coasts of Sicily: Catania, Aci Trezza, Santa Maria La Scala and Santa Tecla. Through a photographic data collection, 95 taxa, representing 17.27% of all Mediterranean marine Heterobranchia, were reported. The order with the highest number of found species was that of Nudibranchia. Among the study areas, Catania, Santa Maria La Scala and Santa Tecla had not a remarkable difference in the number of species, while Aci Trezza had the lowest number of species. Moreover, among the 95 taxa, four species considered rare and six non-indigenous species have been recorded. Since the presence of a high diversity of sea slugs in a relatively small area, the central-eastern coast of Sicily could be considered a zone of high biodiversity for the marine Heterobranchia fauna.

Adult E. timida have been described to feed on the unicellular alga Acetabularia acetabulum in their natural environment. The suitability of E. timida as a laboratory model culture system including its food source was studied. Results: In contrast to the literature reporting that juvenile E. timida feed on Cladophora dalmatica first, and later on switch to the adult diet A. acetabulum, the juveniles in this study fed directly on A. acetabulum (young, non-calcified stalks); they did not feed on the various Cladophora spp. (collected from the sea or laboratory culture) offered. This could possibly hint to cryptic speciation with no clear morphological differences, but incipient ecological differentiation.

  • DNA Barcoding Reveal Patterns of Species Diversity Among
    www.nature.com/scientificreports OPEN DNA barcoding reveal patterns of species diversity among northwestern Pacific molluscs Received: 04 April 2016 Shao’e Sun, Qi Li, Lingfeng Kong, Hong Yu, Xiaodong Zheng, Ruihai Yu, Lina Dai, Yan Sun, Accepted: 25 August 2016 Jun Chen, Jun Liu, Lehai Ni, Yanwei Feng, Zhenzhen Yu, Shanmei Zou & Jiping Lin Published: 19 September 2016 This study represents the first comprehensive molecular assessment of northwestern Pacific molluscs. In total, 2801 DNA barcodes belonging to 569 species from China, Japan and Korea were analyzed. An overlap between intra- and interspecific genetic distances was present in 71 species. We tested the efficacy of this library by simulating a sequence-based specimen identification scenario using Best Match (BM), Best Close Match (BCM) and All Species Barcode (ASB) criteria with three threshold values. BM approach returned 89.15% true identifications (95.27% when excluding singletons). The highest success rate of congruent identifications was obtained with BCM at 0.053 threshold. The analysis of our barcode library together with public data resulted in 582 Barcode Index Numbers (BINs), 72.2% of which was found to be concordantly with morphology-based identifications. The discrepancies were divided in two groups: sequences from different species clustered in a single BIN and conspecific sequences divided in one more BINs. In Neighbour-Joining phenogram, 2,320 (83.0%) queries fromed 355 (62.4%) species-specific barcode clusters allowing their successful identification. 33 species showed paraphyletic and haplotype sharing. 62 cases are represented by deeply diverged lineages. This study suggest an increased species diversity in this region, highlighting taxonomic revision and conservation strategy for the cryptic complexes.

Box 1346, Kane'ohe, Hawai'i, 96744, Email: skarl@hawaiLedu Abstract - Genera in the largest family of the suborder Sacoglossa (Mollusca; Opisthobranchia), the Plakobranchidae Gray, 1840, have been systematically revised numerous times since the 1800s. Several authors have questioned the validity and inter-relationships of the genera Tridachia Moerch, 1863, Tridachiella MacFarland, 1924, Elysiella Bergh, 1872, Pattydaya Marcus, 1982, Elysia Risso, 1818, and Thuridilla Bergh, 1872. For many other groups, molecular data have proven fruitful in determining the systematic relationships of organisms for which few suitable morphological characters are available. Using DNA sequence data from one nuclear (Histone 3) and two mitochondrial genes (Cytochrome Oxidase subunit I and large ribosomal subunit), we infer the phylogenetic relationships among five of the seven recently recognized genera within the Plakobranchidae. These data question the monophyly of the genus Elysia and suggest that further divisions within the genus may be necessary. Additionally, it appears that the family Boselliidae Marcus, 1982 may be, at least, paraphyletic since one member of the genus Bosellia Trinchese, 1891, clusters within the family Plakobranchidae.
