Search. They are 340 million years old, outlived the dinosaurs and survived mass extinction in three global catastrophes. Cycads: World's Most Endangered Plant Group | Barron's Google Scholar. 2018;121:4760. Seminole breadthe conti, a history of the genus Zamia in Florida. Cycads are in danger of becoming extinct both because they live in endangered habitats such as tropical forests, and because they grow so slowly and reproduce so infrequently. Certain beliefs and practices give cycads prominent roles in conceptions of sense of place and cultural heritage. Xalapa, Veracruz: Instituto de Ecologa; 1999. Because cycads are so hardy and fire-tolerant, they are often the only plants to survive in burned-over maize fields after all other vegetation has been eliminated. This was not always possible, however, for a range of reasons, particularly including knowledge loss that resulted in less than ten total people having any in-depth knowledge whatsoever of cycads. Plant remains. This cookie is set by GDPR Cookie Consent plugin. No other botanical literature on cycads in the region existed. Irene Terry Show all 5 collaborators Goal: Globally, and in Australia, a majority of cycad species are currently listed as vulnerable or endangered. Both in some of the stories about Dhipaka deity in the form of a boy who first brought maize to peopleand the origins of maize, and as a demonstration of the ongoing connections between maize and cycads and the ability of cycads to protect and benefit the maize crop, one can find konlif spoken of as Dhipak himself, as well as an embodiment of Dhipaks evil grandmother or another adversary (this dual nature may also be related to the same phenomenon described under the section on cycads and palms, above, and potentially signifies post-colonization Roman Catholic influences on Indigenous conceptions). What are the benefits of associating the two plants? [Image Gallery: Plants in Danger], "A major impediment to conserving the cycads is the lack of knowledge on them," Nagalingum said. Certain beliefs and practices give cycads prominent roles in conceptions of sense of place and cultural heritage. Karoo cycad. Table S2. See also Fig. Vite A. Etnobotnica de ccadas en comunidades nahuas y mestizas de Tlanchinol, Hidalgo [Masters thesis]. MacNeish RS. Cycads are often mistaken for palms, but are in fact only distantly related. Given the fragmentary knowledge of this field of inquiry prior to the onset of our research, we were eventually able to develop adequate questionnaires (Additional file 2) as we gained field experience learning of many beliefs about and uses of cycads that had never been recorded previously. Andover MA: Peabody Mus Arch, Phillips Academy; 1954. of all species facing some risk of extinction Each country faces its own unique set of challenges to prevent species' extinction. Andover MA: Peabody Mus Arch, Phillips Academy; 1954. Gymnosperms and Pteridophytes. Cycads: The Poached Rhinos of the Plant World - Thoughts In A Garden Trans Am Phil Soc. Saving the most endangered plants in the world They are thought to live for over two millennia [30]. In NEMX, cycad parts are used as recreational drugs, and also by shamans (primarily Nahua and Teenek) who are said to ingest them for entheogenic purposes. Life History and Ecology of the Cycads The commonly grown houseplant called a Sago palm is actually a Cycad. Gutirrez CG. Their descendants of these ancient plants were thought to be "living fossils" that were relatively unchanged since the Age of Dinosaurs. Morelia: Centro de Investigaciones en Geogrfia Ambiental, UNAM-Morelia; 2009. p. 4986. In essence, palms were sacred in both Old and New World cultures prior to contact between the two regions, while cycads were unknown to Spanish colonizers. Orcas have sunk 3 boats in Europe and appear to be teaching others to do the same. . In fact they are often found in fossilised dinosaur poo! The connections between such ritual decorative uses, sacramental food, and other components noted in this article should be studied further. Mexico and northern Central America (Honduras, Guatemala, Belize, El Salvador). We scanned full-text databases (e.g., Google Books) using common local names such as teocintle and chamal, and their variants, to locate non-indexed references. South Africa's ancient cycad plants under threat from poachers | South Other traditional practices across the region include occasional use of sarcotestas as well as detoxified seeds for domestic animal feed, preparation of a rodenticide from the raw seeds to control crop pests (primarily rats and mice), and use of leaves for thatch in the temporary field shelters erected by farmers. Dioon populations with hundreds or thousands of coning females are capable of sustaining many families in a given year, particularly helping tide them over during the months when the previous years maize stores run out (typically MarchJune or later), and before the new maize crop is available (in almost all cycad areas in the region, maize is the principal staple). Several terms combine roots from two languages. Poachers act with impunity knowing they are very rarely caught. The biology of the cycads. Accidental poisonings, when they do occur, are said to result from the overly famished and or insufficiently knowledgeable cooks impatience. Many MNCA communities where cycads are highly valued contain permanently transplanted cycads in public plazas and other highly visible locations. Where cycads are still eaten and appreciated, oral histories typically recalled richer, more nuanced traditions and knowledge than those that persist today. This knowledge is passed down through oral tradition via guild-like associations of participants. They dont move, they dont have stripes like a tiger and they certainly arent black and white and cuddly like a panda. Terms and Conditions, Nevertheless, long-term neurotoxic effects indeed have not been an issue, as we suspected. (2) Cycads are high-status plants associated with power and conferring prestige, e.g., in Vanuatu [29], among the Yanyuwa of Arnhem Land, Australia [26], in Panama [22], and in South Africa [22]. We subjected these scant data to minimal interpretation, and flag excavation methods, chronological uncertainty, and other factors that limit their utility. Florence: Medicea Florenziana Library; 1577. http://teca.bmlonline.it/TecaViewer/index.jsp?RisIdr=TECA0001502569. Across the entire region, cycads are often conceptualized as types of maize, friends of maize, and ancestors of maize. Bachelard G. The poetics of space. The few published Colonial-era herbals were also examined, and certain unpublished archival materials were viewed. Cartas y documentos. Corts H. Quinta carta relacin de Hernn Corts al Emperador Carlos V, Tenuxtitan, 3 de septiembre de 1526. The same can be said in Oaxaca, where Chinantec and to a lesser extent Mazatec speakers consume and value cycad foods at present, Chontal de Oaxaca value them as a maize food of the ancestors, while Zapotec people value them for religious reasons but excoriated them (in communities we visited) as famine foods. decoration on town church, San Jernimo Taviche, Oaxaca, 2008, Tiusinte (Dioon mejiae) in a graveyard in Punuare, Olancho, Honduras as a convenient source of leaves for Day of the Dead wreaths, Tzamaalib (chamal, Dioon edule) in a yard as a source of leaves for religious ceremonies, Tancuime, Aquismn, San Luis Potos, 2016, A crown of thorns fashioned from a yazn-gua (Dioon holmgrenii) leaf, Santiago Textitln, Sierra Sur, Oaxaca, 2008. At present, full and recent taxonomic descriptions and revisions exist for many species, while monographs have been produced of the cycads for a few areas [31, 53, 54]. Dickau R, Ranere AJ, Cooke RG. 13, 14, 15, 16, 17, and 18). Maybe you have walked around your neighborhood and seen the same kind of plant there? 2008;93:1521. 1921;22:1219. The question of whether cycads are conceived as types of palms in MNCA Indigenous and Indigenous-derived cultures is highly contextual. We formulated the following hypotheses: (1) cycads have been and remain important food plants despite their toxicity. It is difficult to believe such similarities could have arisen separately given that they involve identical detoxification practices (particularly ash-washing), cultural beliefs (what constitutes a good tamale), and other aspects of food preparation specific to the two cultures while distinct from anything in the intervening region. Ethnobotany of Mexican and northern Central American cycads (Zamiaceae), Journal of Ethnobiology and Ethnomedicine, https://doi.org/10.1186/s13002-018-0282-z, http://www.ethnobiology.net/what-we-do/core-programs/ise-ethics-program/code-of-ethics, https://doi.org/10.1016/j.sajb.2018.02.022, http://teca.bmlonline.it/TecaViewer/index.jsp?RisIdr=TECA0001502569, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/. An ancient lineage of plants that resembles palm trees and are known as cycads once flourished on the Earth. Indicating deeper relationships, one traditional treatment (remedio) for human enchamalamiento is consumption of palm ash, or of soil in which palms grow [72]. Suchiapa: Univ Politcnica de Chiapas; 2009. Botan Mus Leaflets, Harvard Univ. It is clear that cycads have been, and in some cases continue to be, significant elements in local diets across parts of MNCA. Depending on the nature of the responses, open exploratory interviews lasted from 5 to 30min, and if conditions were amenable, these became in-depth, semi-structured interviews. Correspondence to Yez EL. Pachuca: Univ Aut Estado Hidalgo; 2011. Across the region, other methods, including boiling, baking on coals, and leaching in water and sunlight, are occasionally employed as well. Cycads: status survey and conservation action plan. Leaflets of this species are the preferred wrap for chamal tamales in the Sierra Gorda, Quertaro. There is evidence of several thousand plants going out from the wild in the past couple of years. Neurology. Encephalartos woodii - Wikipedia No Spanish or Indigenous terms or knowledge relate WMX cycads directly to any current or prior food uses, though two common NEMX food-related terms for cycadschamal and teosintleused as recently as the 1980s in Jalisco suggest potential former food uses. 4; 1971. Kew Bull. Soc Nat Res. Leaf crowns are typically partially removed to get at the cones, which are twisted off and then broken apart in situ, and the sarcotesta-covered seeds extracted, placed in sacks, often loaded onto beasts of burden, and taken back to permanent residences for processing as described above. Cotoneaster cambricus a Critically Endangered relic from before the last ice age? Kelley D. Valenzuelas Cave (Tmc 248). Cycads - The Most Endangered Living Things on Earth - Home - FossilPlants In the case of influence on climate, while the maturation of cycad cones and the onset of the harvest are typically associated with the dry season, cycads are not seen in these contexts as having agency per se in weather events. Now scientists find that despite their old-school looks, modern cycads are not actually living fossils at all, but totally different from their bygone relatives. Vovides AP, Iglesias CG. Pagn Jimnez JR. ; History - cycad evolution and the fossil record They are also able to mystically hybridize with maize, producing the multi-colored grains in maize ears [38]. Mem New York Botan G; 2007. p. 14375. The pride in this important element of cultural heritage is widely apparent in the increasing amount of video evidence and commentary available online. In: Vovides AP, Stevenson DW, Osborne R, editors. Table S1. [orig. 2, 3, 4, 5, 6, and 7). As such, it seems the trigger for the evolution of modern cycads "was a change in the climate that is, when global cooling began and when the world started having distinct seasons," Nagalingum said. But the cycads survived! Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. We documented 235 terms and associated uses that 28 ethnic groups have for 57 species in 19 languages across 21 Mexican states and 4 Central American nations. We hope that this article will contribute to a reversal of the trend. In one of the only cases we found of ethno-entomological knowledge of MNCA cycads, konlif in the milpa is known to attract butterfly larvae that eat its leaves, their frass fertilizing the soil. Exploratory interviews established whether people still had detailed knowledge of cycads; if so, we carried out in-depth interviews. We took care to remedy incorrect species names and other confusions in the non-botanical literature, and uncertainties are noted (Additional file 1: Table S1). 31 and 32) (Zea mays mays) (Additional file 1: Tables S1 and S2). Where cycads are no longer eaten but are still utilized for other purposes, particularly in Zapotec and Teenek contexts, cycad consumption often evoked distant shameful memories of dire poverty and lack of maize among elderly first-language speakers. Given the vast and diverse nature of our largely exploratory and descriptive undertaking, we did not intend for our qualitative data to bear rigorous statistical analysis. Nevertheless, recent advances have been made in the Gualaco municipality to reverse this approach, for example through the collaboration of cycad biologists, agronomists, and biologists, and through public education and awareness at events such as cycad fairs (see tiusinte, Additional file 1: Table S1). Proceedings of Cycad 2008: the 8th International Congress on Cycad Biology. It is certainly possible that proto-agriculturists sought out cycad populations to plant maize in for reasons such as this. In Mexico, though we did not find this to be the case, we opted to hide identities and localities to impede plant traffickers who access published data to find informants who can point them to cycad populations. Coral Gables: Cycad 2015 organizing committee, Montgomery Botanical Center; 2015. p. 18. Los antiguos Pames, historia oral de un pueblo. Perez-Arbelaezia. Data from the Sierra de Tamaulipas of 4000years ago suggest that cycads may have attained dietary importance as great as they did in the Greater Antilles and Australia. In circumstances where we had limited time, we sought only the most elderly informants. In: Hofman C, editor. The most sought after Cycads are hundreds of years old when they are hacked out of the ground to be sold for thousands of pounds. Pulido MT, Flores-Vazquez JC, Vite A, Vargas-Zenteno M, Vargas Roldan S, Piedra-Reynoso K, Octavio-Aguilar P, Vovides A. Hidalgo: cuarto lugar en riqueza de ccadas en Mxico. All authors reviewed and approved a draft of this manuscript prior to its submission. All but one Dioon and two Ceratozamia species are Mexican endemics, while Zamia is found throughout New World tropical and subtropical regions. Encephalartos woodii, Wood's cycad, is a rare cycad in the genus Encephalartos, and is endemic to the oNgoye Forest of KwaZulu-Natal, South Africa.It is one of the rarest plants in the world, being extinct in the wild with all specimens being clones of the type. Catacamas, Honduras: Univ Nac Agricultura; 2007. Many contain dangerous neurotoxins or carcinogens, along with spiky leaves sharp enough to draw blood. Cycad neurotoxins, consumption of flying foxes, and ALS-PDC disease in Guam. Report. Such cycad farms and plantations are usually treated as common-property resources even where found on private lands [52]. (2) Traditional cycad food-processing techniques prevent long-term effects on human neurological health. AC and MB received funding from Cycads and the domestication of maize in the Mesoamerican landscape: Elucidating an ancient relationship via genomics, archaeology and cultural geography, a grant from CONACyT FOINS901. Most notable are the similarities of tiusinte (Dioon mejiae) culture to NEMX cycad culture. Berlandier JL, Chovel R. Diario de viage de la comisin de lmites. Austin: U Texas P; 1967. Carrasco M. Cycads, maize, and garfish: the representation of ethnoecological systems in Olmec iconography. In: Proc 3rd Conf Toxicity of Cycads. We requested that local contacts and authorities provide us access to 50% men and 50% women. Both plants are of considerable importance in local culture. Dr Clugston is now a botanist at the Royal Botanic Garden Sydney and working on building up . Journ Arch Sci. Though as a whole they are scattered across MNCA, cycads occur in limited areas and are completely absent from the Mexican central plateau and other arid highland areas.Footnote 1 Given striking ethnobotanical similarities between Honduras and Mexico that originally sparked our curiosity and collaborations [22, 50,51,52], we included both countries as well as intervening Guatemala, El Salvador, and Belize where we were not able to undertake fieldwork. However, non-Indigenous ingredients of European derivation are also incorporated into mestizo recipes, particularly in Honduras. Teocintle (Zamia loddigesii) leaves sprout from underground stems in a fallow, burned-over milpa (maize field in swidden rotation), Tohuaco II, Huautla, Hidalgo, 2016. But Xaba said he is also aware of big collections in Asia, Australia, Europe and South America. (Cycadaceae) en el estado de Nuevo Leon, Mxico. This study is intended to inspire similar efforts elsewhere as a step toward new approaches to cycad conservation that, where possible, are able to draw on old and even discarded beliefs and traditions. Keppel G. Morphological variation, an expanded description and ethnobotanical evaluation of Cycas seemannii A. Braun (Cycadaceae). We documented 16 cycad species used for religious purposes. 2006;26:22857. (5) How are cycads incorporated into traditional land-use management? We excluded non-local names, such as those used in nurseries, public parks, and arboretums, where these are either inventions for commercial purposes, or general names such as zamiceas, ccadas, and cicadceas. Traditional reasons to grow cycads in home gardens, beyond their purely ornamental value, are for access to leaves for religious and secular ceremonies, and occasionally, for access to starch for food (though this presumes enough domestic male and female plants are present in a community to sustain the beetle pollinator population necessary for ensuring fertilization and maturation of female cones). Skin conditions are often the focus of cycad ethnomedicine; in this, a comparison can be made to the recent finding that cycasin in Zamia ulei used traditionally in the Peruvian Amazon in medicines derived from stems is moderately effective against leishmaniasis [76]. Estrategia estatal de conservacin de ccadas (Zamiaceae): una propuesta para el Estado de Hidalgo, Mxico. In many cases, however, in-depth interviews were left for a later time, to allow the interviewee to collect their thoughts. At a deeper level, though, some names reflect the interchangeability of cycads and palms in Roman Catholic religious events, whether for simple expediency or as continuations of pre-Christian uses of cycads at temples and other sacred sites.
