Liparis Loeselii

Abstract According to the Global Strategy for Plant Conservation, 75% of endangered species should be preserved in ex situ collections till 2020. The genus Liparis has a lot of recognised taxons, but only one species, Liparis loeselii (L.) Rich., grows in Europe. L. loeselii is a rare and endangered orchid species occurring in Europe. In Latvia L. loeselii is classified as the third category of endangered and protected species. To develop the best conservation strategy, the knowledge concerning the genetic differences of protected plants in a particular area is crucial. For this purpose, the genetic diversity of L. loeselii populations from different Latvian habitats was tested. The inter-retrotransposon amplified polymorphism method (iPBS) was used for population genetic diversity evolution. In total, 54 accessions from nine habitats were collected and analysed. L. loeselii leaves have a high content of phenols that reduce the quality of extracted DNA. It was found that the percentage of polymorph loci varied among the populations of L. loeselii growing in different habitats; some of the populations were genetically homogeneous. The genetic diversity levels of L. loeselii populations are related with the population age and the growing conditions.

Recently, highly productive breeds of various species of domestic animals have been used in livestock production, which has resulted in the destruction of indigenous breeds of domestic animals around the world, even in our area. This is the first reason why indigenous races and strains have been endangered. Another reason is that domestic, indigenous breeds were crossed with specialized breeds, which were imported, and in that way their genetic diversity was negatively affected. Resistance is lost, adaptation to the conditions in which they were created, the ability to survive in nature. Indigenous breeds of different species of domestic animals, which are recognized in the Republic of Srpska (BiH) are gatačko cattle and buša (cattle), Vlašić pramenka, Podveleška pramenka, Kupres pramenka (sheep), domestic Balkan horned goat (goats), Bosnian mountain horse (horses), mangulica (pigs) and pogrmuša hen or živičarka hen (poultry). By acceding to international conventions, BiH /Republic of Srpska has committed itself to establishing a system of measures that will enable the conservation of biological diversity and the protection of indigenous and endangered breeds of domestic animals. The choice of a strategy for the conservation of diversity, the establishment of an adequate conservation scheme, and the implementation of a conservation strategy are some of the key elements of any process for the conservation of genetic diversity. Preservation of autochthonous and protected breeds of domestic animals is possible through preservation in the original environment (in situ) and preservation outside the original environment (ex situ). There is a possibility of combining these models of conservation of animal genetic resources.

Abstract Engage, educate and raise public awareness of the importance of plant diversity is the means through which plant conservation can be achieved. The Global Strategy for Plant Conservation (GSPC) is a programme to halt the loss of plant diversity and recognize botanical gardens as a partners. This paper investigates the implementation of targets 14 and 15 GSPC in Brazilian botanic gardens specially in education and awareness about plant diversity and trained people. A survey was carried out on the institutional websites of 21 gardens registered in the National System of Botanical Gardens Registration to identify actions that follow the guidelines of these two targets. Websites outdated, difficult access and lack online resources for the public shows us that internet tools are poorly used to divulgation. The target 14's activities performed in most gardens are educational visits and environmental interpretation and explore collections in situ and ex situ from representative species of regional flora. Trained people is held in all gardens but some stand out as important research centers and graduate programs. Despite the efforts Brazilian botanical gardens need improve the public communication and develop strategies to measure the targets progress.

The Face

This study reviews the various conservation strategies applied to the four redwood species, namely coast redwood (Sequoia sempervirens), Sierra redwood or giant sequoia (Sequoiadendron giganteum), dawn redwood (Metasequoia glyptostroboides) and South American redwood or alerce (Fitzroya cupressoides), which are endemic in the USA, China and South America, respectively. All four redwood genera belong to the family Cupressaceae; they are monospecific, share a number of common phenotypic traits, including red wood, and are threatened in their native ranges due to human activity and a changing climate. Therefore, the management objective should be to conserve representative populations of the native species with as much genetic diversity as possible for their future survival. Those representative populations exhibiting relatively high levels of genetic diversity should be selected for germplasm preservation and monitored during the conservation phase by using molecular markers. In situ and ex situ strategies for the preservation of germplasm of the redwoods are discussed in this study. A holistic in situ gene conservation strategy calls for the regeneration of a large number of diverse redwood genotypes that exhibit adequate levels of neutral and adaptive genetic variability, by generative and vegetative methods for their preservation and maintenance in their endemic locations. At the same time, it would be desirable to conserve the redwoods in new ex situ reserves, away from their endemic locations with similar as well as different environmental conditions for testing their growth and survival capacities. In addition, other ex situ strategies involving biotechnological approaches for preservation of seeds, tissues, pollen and DNA in genebanks should also be fully exploited in the face of global climate change.

Para Determinar

Se ha escuchado a nivel mundial el llamado para la conservación de orquídeas, por parte de científicos, profesionales de horticultura, propagadores comerciales y los apasionados entusiastas privados, todos con diferentes opiniones sobre la manera para atacar este problema global. Las noticias han sido desalentadoras en relación al calentamiento global, destrucción de hábitat, desplazamiento de poblaciones nativas por parte de agresivas, exóticas e insostenibles depredaciones /cosechas de plantas y los esfuerzos impotentes para hacer cumplir las protecciones legales. Se han dedicado muchas ideas y esfuerzos para determinar estrategias específicas para la conservación de orquídeas, incluyendo la protección al hábitat, la compra y preservación de los “puntos calientes,” así como las tendencias hacia la creación de reservas hortícolas, tanto nativas (reservas de los Jardines de Lankester, Fundación EcoMinga, Ecuagenera) y ex situ (jardines de orquídeas en Hawái, colecciones bajo vidrio, etc.). Tácticas como un banco de semillas, tecnología ADN, esfuerzos de propagación ex situ, así como eventuales reintroducciones, inherentemente dependen de recursos y propiedades de jardines botánicos y cultivadores comerciales responsables. Es este tipo de trabajo de horticultura el que ha salvado a otros géneros que no corresponden a las orquídeas, tales como Franklinia, Torreya, Wollemia, y especies de orquídeas como Paphiopedilum vietnamense, Epidendrum ilense, y Angraecum longicalcar de la extinción. Los jardines botánicos unidos bajo ciertas organizaciones como la Asociación Americana de Jardines Públicos (American Public Garden Association - APGA) y Jardines Botánicos para la Conservación Internacional (Botanic Garden Conservation International - BGCI), necesitan de una mayor cooperación y coordinación para el éxito de sus esfuerzos para la conservación de plantas. Además, es un aspecto crítico que los jardines botánicos se conecten con la comunidad científica (y viceversa), especialmente aquellos que mejor pueden asesorar sobreaquellas especies más amenazadas. Si las colecciones van a ser utilizadas en forma óptima, las sociedades científicas y de horticultura deben estar más conscientes de sus respectivos activos y prioridades. En el Primer Congreso Internacional para la Conservación de Orquídeas (International Orchid Conservation Congress - IOCC), se adoptaron cuatro resoluciones de la Estrategia Global para la Conservación de Plantas (Global Strategy for Plant Conservation – GSPC en inglés): 1): el 90% de todas las orquídeas amenazadas deberían ser asegurada en colecciones ex situ; 2) el 50% debería constar en programas para su recuperación activa; 3) Se debe considerar que las orquídeas están amenazadas cuando su cosecha no es sostenible; y 4) Para el año 2010, cada niño y niña debe estar consciente de lo que es la diversidad de plantas (incluyendo a las orquídeas). ¿C.mo podemos evaluar si se está logrando el progreso hacia estos admirables objetivos sin que exista una entidad que unifique y que pueda recopilar el progreso, la información y el grado de éxitos alcanzado? Al ver el esfuerzo desplegado en tantos lugares separados, es indudable que se necesita urgentemente este tipo de entidad. Constituye la meta de muchos jardines botánicos y una meta específica del Instituto Smithsoniano, el promover la diseminación de conocimientos y comprensión. Con este fin en mente, el anterior objetivo #4 constituye una particular prioridad. A pesar de que alcanzar la meta del 100% de conciencia compartida en relación a la diversidad de plantas para el año 2010, hemos iniciado un proyecto que nos permita comprender y finalmente corregir el llamado síndrome de “Ceguera relativa a las Plantas,” bajo el cual la persona promedio no considera que las plantas son seres vivientes (en el mismo sentido de los animales). Mediante el uso de encuestas y entrevistas personales, se está analizando este síndrome generalizado y penetrante para determinar sus caracter.sticas demográficas, hombre/ mujer, urbano/rural, jóvenes/ viejos, etc. Es imperativo para los educadores que identifiquen la edad en la cual dichas actitudes empiezan a introducirse en la psiquis de los jóvenes. Es necesario aplicar ciertas técnicas que permitan elevar el grado de conciencia de los individuos de todas las edades en relación a la importancia de la diversidad de las plantas y su conservación. Esto puede tomar la forma de presentaciones, exposición a especies representativas, paseos de campo y otras oportunidades educativas, que permitan cultivar un enfoque mental que comprenda y a la final proteja el mundo natural.

Restoration Process

The Threatened Species Programme at the South African National Biodiversity Institute, Kirstenbosch National Botanical Garden, is integrated to include both ex situ and in situ conservation activities. Plant conservation is driven by South Africa’s Strategy for Plant Conservation which was developed in response to the Global Strategy for Plant Conservation. This case study examines the conservation of Erica verticillata (whorl heath), a flagship for threatened species at Kirstenbosch, and documents the integration of ex situ with in situ conservation at three areas on the Cape Flats. The whorl heath was thought to be extinct by 1950. Horticulturists have since rediscovered eight clones in botanic gardens worldwide, the Heather Society and commercial growers. Ex situ conservation in botanic garden collections and the Millennium Seed Bank has since allowed in situ conservation in the critically endangered Cape Flats Sand Fynbos vegetation type. The process of restoring the whorl heath presented many challenges. Initially attempts were hampered by limited available knowledge on suitable niche habitats. Pioneering work carried out at Rondevlei Nature Reserve identified the suitable habitat and this was applied in subsequent in situ work at Kenilworth Racecourse Conservation Area and at Tokai Park – the only natural areas remaining in or near this species’ historical distribution range. Successful re-establishment of this species depends upon its capacity to recruit after fire, which is an essential ecological process in the fynbos. Many clones have been in cultivation for a long time and are poor seed producers: seed production was first recorded at Rondevlei only after additional clones were planted together. Only one population (Rondevlei) to date has seen a fire and thus has recruited seedlings; however these are competing with vigorous companion plants. The study continues and is currently exploring the role of herbivory in the restoration process. The key lesson learnt to date is the need to include sustainable management of the entire ecosystem in the restoration process and not limit it to single species. Success in restoring a species depends upon a healthy stand of the vegetation type in place, along with pollinators and other key fauna and other natural ecosystem processes. It is recommended that successful re- establishment of a species in fynbos requires the reintroduced population to survive three fire cycles.

Research Highlights: This study is the first to examine the genetic diversity of Michelia shiluensis (Magnoliaceae). High genetic diversity and low differentiation were detected in this species. Based on these results, we discuss feasible protection measures to provide a basis for the conservation and utilization of M. shiluensis. Background and Objectives: Michelia shiluensis is distributed in Hainan and Guangdong province, China. Due to human disturbance, the population has decreased sharply, and there is thus an urgent need to evaluate genetic variation within this species in order to identify an optimal conservation strategy. Materials and Methods: In this study, we used eight nuclear single sequence repeat (nSSR) markers and two chloroplast DNA (cpDNA) markers to assess the genetic diversity, population structure, and dynamics of 78 samples collected from six populations. Results: The results showed that the average observed heterozygosity (Ho), expected heterozygosity (He), and percentage of polymorphic loci (PPL) from nSSR markers in each population of M. shiluensis were 0.686, 0.718, and 97.92%, respectively. For cpDNA markers, the overall haplotype diversity (Hd) was 0.674, and the nucleotide diversity was 0.220. Analysis of markers showed that the genetic variation between populations was much lower based on nSSR than on cpDNA (10.18% and 77.56%, respectively, based on an analysis of molecular variance (AMOVA)). Analysis of the population structure based on the two markers shows that one of the populations (DL) is very different from the other five. Conclusions: High genetic diversity and low population differentiation of M. shiluensis might be the result of rich ancestral genetic variation. The current decline in population may therefore be due to human disturbance rather than to inbreeding or genetic drift. Management and conservation strategies should focus on maintaining the genetic diversity in situ, and on the cultivation of seedlings ex-situ for transplanting back to their original habitat.

To date, there have been only limited attempts to conceptually unify ex situ and in situ approaches as parts of an integrated conservation methodology. This paper is an attempt of such conceptual integration of existing approaches for the efficient conservation of rare and endangered plant species. My integration of available plant conservation biology literature is based on the idea that ecologically significant species genetic variation is of primary importance for plant conservation. This idea is used for providing guidelines about inventory of existing populations, sampling and propagating sampled material, and use of this material in species recovery actions.

Threatened Plant Species

In order to achieve certain targets of the Global Strategy for Plant Conservation (GSPC), countries should aim to have at least 75% of their threatened species preserved in ex situ genetically representative collections, preferably in the country of origin, and at least 20% of the threatened species must be available for recovery plans and restoration programs (Target 8). Assessing the conservation value of ex situ collections is needed in order to identify the gaps in gene banks and to determine the baseline situation. Selection of the target species for conservation followed the Regional Responsibility criterion, as the first-order of priority at the local level with highest ranking given to species whose distribution is endemic to the study area. Data analysis was performed on 85 species listed in the Valencian Catalog of Threatened Plant Species (VCTPS) stored in the Germplasm Bank Collections of Valencian Flora, Spain. Our results show that conservation value of an ex situ collection will depend on whether the analysis is based on the representation of species (i.e. the presence or absence of species in an ex situ collection) or based on their representativeness (i.e. how well the collected and stored natural populations represent the “theoretical” species genetic diversity and what is the potential to produce plants for recovery actions, summarized in the proposed index R4). For 85 species listed in VCTPS the existing ex situ seed bank collections keep samples of 91.8% (78 species), indicating good representation. However, the criteria accounting for number of populations collected and quality of the stored germplasm revealed that less than 50% of the listed species are properly preserved in the ex situ collections.

AbstractThe conservation of species listed in the Bern Convention and European Directive 1992/43/EEC (so-called policy species) is mandatory for European Union (EU) countries. We assessed the conservation status of Italian policy species, based on the IUCN categories and criteria, to evaluate the effectiveness of existing protection measures at the national level. Among the 203 vascular plants, bryophytes and lichens evaluated, 41.9% are categorized as threatened, and one is already extinct, indicating that the protection measures for policy species are inadequate. Our results for the Italian policy species are consistent with those of an assessment at the EU level. Conservation priorities should be established at both the national and regional scales. An effective conservation strategy is needed, and in situ and ex situ actions focused on threatened species should be promoted.
