Once again, we are seeing and tasting the result of more than a century of mango research and exploration. Our collection at The Fairchild Farm, now totaling more than 600 living accessions, was gathered from all corners of the mango world. During this Ayear’s International Mango Festival, you can enjoy the flavors, colors and incredible stories from our collection. This year, we launched a new program to study the genetics of our mango collection, adding new dimension to our ongoing tropical fruit research. Visitors to the new Raymond Baddour DNA Laboratory in the Paul and Swanee DiMare Science Village now have the opportunity to see mango DNA research in action. To learn about mango DNA, we gather leaf samples from our living mango accessions at The Fairchild Farm and flash-freeze them in the lab with liquid nitrogen. In a cloud of steam, we grind the super-cooled leaf samples into a fine, green powder. We use our lab equipment to transform that powder into samples of pure DNA. As we stockpile hundreds of test tubes of mango DNA in our freezer, we are building a tremendous resource for studying the mango’s origin, diversity and potential breeding opportunities. Our team of staff, students and volunteers is studying the mango DNA samples in our rapidly expanding collection. This summer, a group of high school interns will help the project grow, bringing new samples from The Farm to the laboratory for analysis. In this issue, Noris Ledesma, Fairchild’s curator of tropical fruit, and Dr. Richard Campbell, our director of horticulture, explain the incredible value of our collection for genetic research and the future of mangos (“The Call of the Wild,” p. 31). Emily Warschefsky, a Ph.D. Student at Florida International University, describes some of our goals in building this research at Fairchild (“Message in a Bottleneck,” p. 34). All of the world’s major crop plants, including rice, wheat, tomatoes and many others, have been studied in detail through decades of DNA research. Results of that research have helped rescue those crops from pests and diseases, and have brought valuable new varieties to the market. We are only in the beginning stages of that kind of research on mangos, but we see a bright future ahead. Any advances we make in mango genetics can positively impact the livelihood of people throughout the tropics. Along with the mango, there are hundreds of other kinds of tropical plants waiting to be studied. Take a close look at our plants the next time you visit Fairchild, and you might catch a glimpse of the small metal tags we use to identify and keep track of more than 12,000 plants. The majority of those plants have never been the subject of detailed genetic research. Within our collection stand many new research opportunities just waiting to be tackled. In the years ahead, you will see increasing numbers of researchers and students clipping leaf samples from plants throughout the Garden and processing those samples in our labs. You can look forward to new discoveries as we unlock the secrets held within the genes of tropical plants. I hope you savor this mango season and dream of an even more flavorful future as science moves forward at Fairchild. Best regards, Carl Lewis, Ph.D. Director from the chief operating officer he temperature is warmer, the humidity higher and our umbrellas are in hand, because, after all, afternoon showers are expected—all clear signs that summer has arrived. TFairchild is a tropical garden. Its 83 acres exhibit some of the world’s most exotic tropical plants. Many of these plants thrive in the tropics, where temperatures average 80 degrees year-round with consistent high humidity. South Florida is technically in the subtropics, which means our average summertime temperature is in the upper 80s, but we experience dry, cooler months in the winter. Summertime in South Florida is as close as we get to true tropical weather. As a result, the tropical plants in the Garden are at their most spectacular during these summer months. They respond to the higher temperatures and humid conditions by seemingly bursting with verdant euphoria. Summer also means mangos. Hearing “thump” when the first ripe mango of the season hits the ground is the tropical world’s version of Groundhog Day: an unmistakable indication that summer is here again. Fairchild celebrates the mango harvest with the annual International Mango Festival (July 12–13), and this year’s event will once again bring mango mania to South Florida. No other fruit arouses as much passion as the mango; the variety of flavors and cultural resonances make it a truly global treasure. Our tropical fruit team is working diligently to capture this global crop’s cultural, horticultural, agricultural and scientific information. The Mango Festival is the culmination of the full spectrum of critically important work related to the king of tropical fruit. Summer also means family trips, vacations and weekend adventures. Be sure to make time to visit Fairchild this summer. There are many activities designed to keep you cool during your visit, like walking tours of the Rainforest and The Edible Garden, delicious smoothies of fresh fruit from The Fairchild Farm, tram tours and, of course, the Wings of the Tropics exhibit and adjacent Glasshouse Café, which is a perfect place to cool off and enjoy a great meal while watching the dance of the butterflies. I hope you enjoy the wonderful articles in this issue. Our staff spends a great deal of time carefully crafting stories that illustrate both the botanical world at large and the Garden’s important work. For instance, we present a great article about the oft-overlooked beauty and utility of seeds, a fascinating look into consumption and conservation of edible orchids in China, a beautiful travel and photo log of plants from the Mojave Desert, a delicious recipe for mango ceviche that is perfect for all of those mangos you’re harvesting from your trees, a step-by-step guide to growing the sacred lotus and so much more. So this summer, come on over and enjoy mangos, the beauty of tropical plants in full splendor and the endless possibilities of fun and learning that are offered only here at Fairchild.

    2021 US Dollars Butterfly Pupae To the Butterfly Keeper January 2021 2021 Butterfly Pupae Supplies Happy New Year, thank you for downloading our 2021 US$ pupae price list and forms. Last year was a challenge for everyone and the damage caused by the pandemic to the Butterfly trade was considerable. Many facilities were forced to close their doors to the public and therefore received no income. We ourselves had to shut for seven months out of twelve and as I write in January there is no sign of us being allowed to open in the next two months at least. This hardship has been multiplied in the situation of our suppliers as they have no government support. IABES did manage to get some financial support to them during the first extensive lockdown but spread over many breeders it could not replace the income they get from their pupae. Along with problems here and at source the airline industry is really struggling and getting what pupae we can use, onto a suitable flight has caused us many a sleepless night telephoning Asia at one extreme and South America at the other. However, we trust that we will come out of this global problem and be able revert to normal sometime during the spring. We still guarantee that all our pupae conform to all international standards and comply with all current legislation. We have a system in place that gets pupae to US houses in an efficient manner. We have had a very small price increase this year mainly because of increased airfreight costs.

  • Collection and Evaluation of Under-Utilized Tropical and Subtropical Fruit Tree Genetic Resources in Malaysia
    J]RCAS International Symposium Series No. 3: 27-38 Session 1-3 27 Collection and Evaluation of Under-Utilized Tropical and Subtropical Fruit Tree Genetic Resources in Malaysia WONG, Kai Choo' Abstract Fruit tree genetic resources in Malaysia consist of cultivated and wild species. The cul­ tivated fruit trees number more than 100 species of both indigenous and introduced species. Among these fruits, some are popular and are widely cultivated throughout the country while others are less known and grown in small localized areas. The latter are the under-utilized fruit species. Apart from these cultivated fruits, there is also in the Malaysian natural forest a diversity of wild fruit tree species which produce edible fruits but are relatively unknown and unutilized. Many of the under-utilized and unutilized fruit species are known to show economic potential. Collection and evaluation of some of these fruit tree genetic resources have been carried out. These materials are assessed for their potential as new fruit trees, as sources of rootstocks for grafting and also as sources of germplasm for breeding to improve the present cultivated fruit species. Some of these potential fruit tree species within the gen­ era Artocarpus, Baccaurea, Canarium, Dimocarpus, Dialium, Durio, Garcinia, Litsea, Mangif era, Nephelium, Sa/acca, and Syzygium are highlighted. Introduction Malaysian fruit tree genetic resources comprise both cultivated and wild species. There are more than 100 cultivated fruit species of both major and minor fruit crops. Each category includes indigenous as well as introduced species. The major cultivated fruit crops are well known and are commonly grown throughout the country.

  • The Genetics and Evolution of Iridescent Structural Colour in Heliconius Butterflies
    The genetics and evolution of iridescent structural colour in Heliconius butterflies Melanie N. Brien A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy The University of Sheffield Faculty of Science Department of Animal & Plant Sciences Submission Date August 2019 1 2 Abstract The study of colouration has been essential in developing key concepts in evolutionary biology. The Heliconius butterflies are well-studied for their diverse aposematic and mimetic colour patterns, and these pigment colour patterns are largely controlled by a small number of homologous genes. Some Heliconius species also produce bright, highly reflective structural colours, but unlike pigment colour, little is known about the genetic basis of structural colouration in any species. In this thesis, I aim to explore the genetic basis of iridescent structural colour in two mimetic species, and investigate its adaptive function. Using experimental crosses between iridescent and non-iridescent subspecies of Heliconius erato and Heliconius melpomene, I show that iridescent colour is a quantitative trait by measuring colour variation in offspring. I then use a Quantitative Trait Locus (QTL) mapping approach to identify loci controlling the trait in the co-mimics, finding that the genetic basis is not the same in the two species. In H. erato, the colour is strongly sex-linked, while in H. melpomene, we find a large effect locus on chromosome 3, plus a number of putative small effect loci in each species. Therefore, iridescence in Heliconius is not an example of repeated gene reuse. I then show that both iridescent colour and pigment colour are sexually dimorphic in H.

    APPENDIX D.2 Plant Survey Memorandum Athos Memo Report To: Aspen Environmental Group From: Lehong Chow, Ironwood Consulting, Inc. Date: April 3, 2019 Re: Athos Supplemental Spring 2019 Botanical Surveys This memo report presents the methods and results for supplemental botanical surveys conducted for the Athos Solar Energy Project in March 2019 and supplements the Biological Resources Technical Report (BRTR; Ironwood 2019) which reported on field surveys conducted in 2018. BACKGROUND Botanical surveys were previously conducted in the spring and fall of 2018 for the entirety of the project site for the Athos Solar Energy Project (Athos). However, due to insufficient rain, many plant species did not germinate for proper identification during 2018 spring surveys. Fall surveys in 2018 were conducted only on a reconnaissance-level due to low levels of rain. Regional winter rainfall from the two nearest weather stations showed rainfall averaging at 0.1 inches during botanical surveys conducted in 2018 (Ironwood, 2019). In addition, gen-tie alignments have changed slightly and alternatives, access roads and spur roads have been added. PURPOSE The purpose of this survey was to survey all new additions and re-survey areas of interest including public lands (limited to portions of the gen-tie segments), parcels supporting native vegetation and habitat, and windblown sandy areas where sensitive plant species may occur. The private land parcels in current or former agricultural use were not surveyed (parcel groups A, B, C, E, and part of G). METHODS Survey Areas: The area surveyed for biological resources included the entirety of gen-tie routes (including alternates), spur roads, access roads on public land, parcels supporting native vegetation (parcel groups D and F), and areas covered by windblown sand where sensitive species may occur (portion of parcel group G).

  • Ciclo De Vida De Las Especies Caligo Memno (Lepidóptera: Brassolinae) Y Heliconius Ismenius (Lepidóptera: Heliconinae) Bajo Condiciones Controladas
    Ciclo de vida de las especies Caligo memno (Lepidóptera: Brassolinae) y Heliconius ismenius (Lepidóptera: Heliconinae) bajo condiciones controladas Karla J. Cantarero*, Oscar M. Canales*, Aaron A. Mendoza*, Luis B. Martínez* RESUMEN Honduras es un país con mucha diversidad de mariposas diurnas y nocturnas; su singularidad, belleza y colorido nos lleva a trabajar estos insectos como un recurso forestal no maderable promisorio que se puede implementar en el país debido a su alta biodiversidad, la cual ha sido subvalorada. La presente investigación trata acerca del estudio del ciclo de vida de Heliconius ismenius (Lepidóptera: Nymphalidae: Heliconinae) y de Caligo memnon (Lepidoptera: Nymphalidae: Brassolinae), realizado en la ciudad de Tegucigalpa, específicamente en el laboratorio de entomología y el Mariposarío ¨Anartia¨ de la Universidad Nacional Autónoma de Honduras. Durante la cría también se registraron aspectos de la biología y etología de ambas especies, como son: requerimientos alimenticios, migración, tiempo invertido en la alimentación, crecimiento, entre otros. El método aplicado se basó en el marco general que se ha usado para la implementación de zoocriaderos de lepidópteros, que selecciona un número reducido de individuos (pie de cría para cada especie) de alguna fuente para comenzar con el proceso. Durante este proceso se determinó que la especie Caligo memnon se adaptó muy bien a las condiciones, por el contrario se cree que el ciclo de vida de Heliconius ismenius se vio interrumpido por las condiciones ambientales en ese momento. Ambas especies se adaptan muy bien a condiciones de laboratorio y de campo pero con algunas diferencias en cuanto al tiempo de crecimiento, ya que en la etapa de laboratorio se vio una leve diferencia en cuanto al tiempo de crecimiento no así en la etapa de campo.

  • The Speciation History of Heliconius: Inferences from Multilocus DNA Sequence Data
    The speciation history of Heliconius: inferences from multilocus DNA sequence data by Margarita Sofia Beltrán A thesis submitted for the degree of Doctor of Philosophy of the University of London September 2004 Department of Biology University College London 1 Abstract Heliconius butterflies, which contain many intermediate stages between local varieties, geographic races, and sympatric species, provide an excellent biological model to study evolution at the species boundary. Heliconius butterflies are warningly coloured and mimetic, and it has been shown that these traits can act as a form of reproductive isolation. I present a species-level phylogeny for this group based on 3834bp of mtDNA (COI, COII, 16S) and nuclear loci (Ef1α, dpp, ap, wg). Using these data I test the geographic mode of speciation in Heliconius and whether mimicry could drive speciation. I found little evidence for allopatric speciation. There are frequent shifts in colour pattern within and between sister species which have a positive and significant correlation with species diversity; this suggests that speciation is facilitated by the evolution of novel mimetic patterns. My data is also consistent with the idea that two major innovations in Heliconius, adult pollen feeding and pupal-mating, each evolved only once. By comparing gene genealogies from mtDNA and introns from nuclear Tpi and Mpi genes, I investigate recent speciation in two sister species pairs, H. erato/H. himera and H. melpomene/H. cydno. There is highly significant discordance between genealogies of the three loci, which suggests recent speciation with ongoing gene flow. Finally, I explore the phylogenetic relationships between races of H. melpomene using an AFLP band tightly linked to the Yb colour pattern locus (which determines the yellow bar in the hindwing).
