Abstract (sommario):

Zoological collections house a huge range of biological diversity preserved in a wide variety of ways ranging from microscope mounts to whole animals preserved in fluids. The result is that these collections consist of a wide range of differing materials which can make the long term care and conservation of such collections a considerable challenge. This workshop is designed for museum professionals with the aim of giving an introductory overview on museum conservation approaches towards the care of zoological collections. This will be achieved through identifying the key risks and looking at the application of both remedial and preventative conservation methodologies to their care. The format of the workshop will be lectures on specific topics with group discussions, along with (where feasible) activities in small groups and practical examinations of specimens. Topics covered will include: Introduction to the concepts of ‘museum conservation’ and its application within the Natural Sciences. The types of material found in zoological collections – an overview of the core collection types, the chemistry of preservation and the potential long term challenges these present. An overview of the key agents of deterioration. Environmental effects and how to recognise them. Awareness of hazardous materials and core H&S issues encountered with the care and handling of zoological collections. Assessing collections and deciding conservation priorities. Fur, feathers and bones - practical conservation approaches to cleaning, consolidation and repair. Fluid collections - practical conservation approaches to handling, identifying fluids and carrying out remedial activities. Other key collection areas – e.g. conservation of entomology and other dried invertebrate collections; microscope slide collections. Consideration of the care and conservation of specialist collections e.g. historic models such as Blaschka glass models. Discussion and feedback from attendees will be a core part of the day.

Abstract (sommario):

A museum plays a central role in conserving cultural heritage. Hence, conserving museum collections is pivotal for preserving the values of the collection. The museum of National Awakening has a potential national collection that requires curative conservation due to its damaged condition, i.e., Sultan Thaha Robes. However, the conservation effort lacked written and visual documentation of the collection due to the collection's urgency, causing it difficult for conservators to access the conservation-related information. This paper presents a critical review of conservation stages performed on Sultan Thaha Robes while suggesting a complete, systematic conservation solution based on the theoretical collaboration of textile conservation experts.

Abstract (sommario):

On May 16th 2007 the British Library Centre for Conservation (BLCC) was opened, providing Conservation staff and Sound Archive Technical Services staff with a new purpose-built base from which to operate. The new building allowed them to be brought together onto the same site as their colleagues and co-located them with the collections for the first time. A BLCC-based programme of professional development events, special interest group events and public tours is providing Collection Care, Conservation, and the Sound Archive Technical Section with a public profile and a voice for communicating key messages about the Library’s stewardship of its collections and about caring for collections generally. The Centre, already a milestone in the history of collection care at the Library, is continuing an existing and ambitious change programme, giving the perfect opportunity to examine all aspects of operations and make changes of benefit to the Library and its staff.

Abstract (sommario):

THE TERM CONSERVATION refers to the whole subject of the care and treatment of valuable materials. Its definition is two-fold: (1) the control of the environment to minimize the decay of artifacts and materials; and (2) treatment of materials to arrest decay and to stabilize them against further deterioration. Restoration is the continuation of the treatment to return an object without falsification to a state in which it can be displayed (Howie, 1992; series editor's preface). The vast number of specimens in invertebrate paleontology collections makes treatment or restoration impractical or even impossible except for remarkable display specimens. It is possible, however, to control the environment, both physical and procedural, in which collections are maintained. It is easier to prevent deterioration than to fix it once it has occurred. This is the principle of preventive conservation.There is a general misconception, held by many paleontologists, that there are no conservation concerns with paleontology collections, or, if any, the concerns are minor. This unfortunately is not the case; although fossils and their rock matrix have lasted hundreds of millions of years in the earth, once excavated they are subject to many forces of destruction (Crowther and Collins, 1987). Problems in collections occur as a result of many different factors: inappropriate storage environment; inappropriate application of a “universal” treatment; or unstable materials used in preparation and treatment. Minerals such as pyrite may oxidize; shales crack and delaminate. Prepared specimens may include introduced materials such as consolidants and glues that themselves are subject to deterioration. Research into conservation of natural history materials has grown significantly over the past two decades. This paper will emphasize preventive conservation principles to address some of the conservation concerns particularly relevant to paleontological specimens and suggest some practical ways of reducing the risks to the collections.

Abstract (sommario):

AbstractWith 10% of trees (> 8,000 species) threatened with extinction there is an urgent need for botanical gardens to protect threatened trees in dedicated conservation collections. Species conservation is mentioned in the mission statements of most major botanical gardens, yet the actual conservation value of existing ex situ tree collections is low. We conducted interviews with members of the botanical garden community and organized a symposium at the 5th Global Botanic Gardens Congress to identify challenges and collect recommendations to improve living ex situ tree collections. We summarize and evaluate this information to facilitate gardens becoming more effective agents for global tree conservation. Experts agree that gardens offer valuable strengths and assets for tree conservation. Some challenges exist, however, including a lack of strategic conservation focus, collection management limitations, gaps in fundamental biological information for trees, and a lack of global coordination. Solutions are offered to facilitate gardens and arboreta of all sizes to participate more effectively in tree conservation. Prioritizing genetically diverse tree collections, participating in conservation networks, developing tree-specific conservation models and guidelines, and strengthening tree science research efforts are a few examples. Most importantly, a more coordinated global effort is needed to fill knowledge gaps, share information, and build conservation capacity in biodiversity hotspots to prevent the loss of tree species.

Abstract (sommario):

Plant species of Annonaceae family were collected in Purwodadi Botanic Garden (PBG) needs ex-situ conservation efforts to prevent threat of extinction. Annonaceae plants collection in PBG have experienced dynamics over the past of 12 years which affect to diversity and conservation efforts. This study aimed to determine the dynamics or development of Annonaceae plants collection in PBG for the past of 12 years and how their conservation efforts. The methods were used are primary and secondary data collections from Registration Unit, measurement of stem diameter, plant height, branch-free stem height (BFS) of Annonaceae plants collection and microclimatic data (temperature, humidity, soil pH and light intensity) in each block of Annonaceae plants collection. Data were analyzed descriptively and by Principal Component Analysis using the statistical program PAST 4.0. The Annonaceae plant collections in PBG have fluctuated in the number of plants, genera, species, specimens and unidentified species with the addition of 28, 10, 6, 58, and 7 plants respectively. There were also 81 times of species identity changes. Annonaceae plant collections in PBG was able to well adapt and develop based on the average of stem diameter and BFS, with humidity and light intensity became the most influential environmental factors for plant growth. The management of Annonaceae plant collections in PBG consisted of the maintenance activities and studies to support the conservation. By regulating and manipulating of humidity and light intensity in Annonaceae plant collections, plant growth will increase and well maintenance. Management efforts can be planned and developed properly by knowing the dynamics of plant collections.

Abstract (sommario):

Deaccessioning in collections can be controversial because of the value associated with some taxa and their conservational, historical, educational, display and research significance within the collection. Twenty-one horticultural institutions completed a survey on the protocols for deaccessioning plant material. The resulting data were collated to provide a comparison of the different approaches institutions take towards deaccessioning their collections. This study has identified that conservation and education are the most important factors in managing garden collections. Accession data of high quality is an essential part of managing a collection, but poor accession data should not be a reason to deaccession plants. Space constraints are the primary factor behind the deaccessioning of collections. This paper is a summary of the research project completed by the author for the BSc in Horticulture with Plantsmanship at the Royal Botanic Garden Edinburgh (RBGE).

Abstract (sommario):

The author has spent 30 years co-ordinating the International Conifer Conservation Programme (ICCP), based at the Royal Botanic Garden Edinburgh, and uses this significant milestone to reflect on some important aspects of managing genetic resources in plants of conservation concern. The main driver of the ex-situ component of the ICCP has been to develop robust protocols for broadening the genetic base of threatened conifers and a range of conservation dependent Chilean woody plants in cultivation. This is achieved using well-documented known wild origin material distributed through a dedicated network of ‘safe sites’. Examples of threatened species for which collection and cultivation of a breadth of genetic material has enabled meaningful conservation are given here. The strategy to increase genetic material in cultivation sometimes involves using novel methods including conservation hedges. The great challenge facing all managers of botanical collections is how to develop effective programmes that integrate ex-situ with in-situ conservation. The biggest contribution collection managers and growers can make is to maximise the value of collections in their care and actions which achieve this are listed.

Several methods of plant preservation are currently used in the Republic of Kazakhstan: 1) field gene banks in natural growing areas and pomological collections; 2) preservation of seeds at +4°С, –18°С, and –196°С; 3) сold storage of in vitro shoots at +4°С and +10 ± 2°С; 4) cryopreservation of plant tissues and organs at –196°C; 5) preservation of plant DNA at –80°C.Ex situ field collections of plants in Kazakhstan are maintained in botanical gardens of the Republic, arboretums, pomological gardens, nurseries, peasant and farm enterprises, and personal plots. The largest collection of fruit and berry plants is located in the Pomological Garden and includes about 4 thousand varieties, more than 40 thousand hybrids and wild forms of various crops.The Republic of Kazakhstan has about 42,000 accessions in the seed collection. The cereal crop collection is mainly concentrated in the Kazakh Research Institute of Agriculture and Plant Growing – 1/3 of the national genetic resources. The main seed collection of vegetable crops and potatoes (14,700 accessions) is held by the Kazakh Research Institute of Potato and Vegetable Growing. Collections are also available at the Institute of Botany and Phytointroduction and in the Institute of Plant Biology and Biotechnology (IPBB), with the storage mode of + 4°C and –18°C. IPBB also uses cryopreservation technology at –196°C for seed storage.The main in vitro collection of Kazakhstan is kept at the IPBB at + 4°С and +10 ± 2°С; it includes more than 140 accessions of various fruit, berry, nut, vegetable, ornamental, and woody crops, grapes, potatoes, etc. A cryogenic collection of seeds, shoot tips, dormant buds, and embryonic axes in liquid nitrogen (–196°C) is found only in IPBB. The collection includes more than 700 accessions.

Abstract (sommario):

The museums located in the North-Western part of Nigeria use both preventive and curative conservation in preserving the collections in their custody. In applying preventive conservation, the museums manage the risks to collections through the lens of the agents of deterioration. The REORG method, adoption of proper collection management practices, passive method of indoor climatic management and good house-keeping were the preventive conservation methods used in the museums. Dry cleaning, wet cleaning and chemical treatment were used in curative conservation. Although the two conservation methods were used in the museums, each has its peculiar benefits. The preventive conservation method aims to prevent or reduce damage while curative conservation is the method of choice when damage has occurred. This study discusses both types of conservation as applied in North-West museums

Abstract (sommario):

AbstractThe practice of preventive conservation of cultural heritage consists of “all measures and actions aimed at avoiding and minimizing future deterioration or loss” of it (ICOM-CC, 2008). Unlike conservation treatments, preventive conservation deals with entire collections and their surrounding environment. It is known that exposing historical objects to the environment has a significant impact on their degradation process. Studying and managing risk factors is an indispensable practice within the management policies of any cultural institution. The National Institute for Astrophysics (INAF) holds some valuable historical collections, heritage derived from the Italian contribution to astronomy over the centuries. The management and protection of these collections faces many challenges. A preventive conservation plan, aimed at assessing and managing risks that threaten the collections, may offer many long-term benefits, allowing us to use available resources in the best possible way. In the past few years INAF-Astronomical Observatory “G.S.Vaiana” of Palermo has been working on the development of preventive conservation projects for its archival, bibliographic and scientific heritage. The present contribution reports on these ongoing experiences and intends to stimulate a discussion within the scientific community in order to individuate the problems we are called to respond to in Astronomical Observatories.

Abstract (sommario):

There is evidence to suggest that visitors to zoological collections prefer to see large, active mammals. To attract visitors, zoos and aquariums might be tempted to select for mammal species in their collection plans to maintain visitor interest. However, collections also play a role in endangered species breeding, many of which are not mammals. Using International Zoo Yearbook data, we explored the number of species of mammals, birds, reptiles, amphibians, fish and invertebrates housed in collections across the globe. These data were compared against three hypothetical collection plan strategies: a) marketing, as shown by the prevalence of each taxon in toy retail; b) biodiversity, in which taxa in proportions that reflect their wild abundance, and c) in which all six taxa are represented equally. The global zoological collection plan indicated that on average, collections contain more bird species than other taxonomic groups, followed by fish, mammals, invertebrates, reptiles and amphibians.

Abstract (sommario):

In May 1975 the newly-created North East Fife District Council inherited museum collections in the burghs of Cupar, Newburgh and St Andrews. All three museum collections had suffered years of neglect through lack of curatorial care. In late 1982 the district council appointed a curator whose priority tasks were the cataloguing and conservation of existing collections. The museum service moved into its present accommodation in Cupar (the old police station) in December 1984. Since then cataloguing and conservation work has been fully operational. In November 1984 a Manpower Services Commission team was appointed, including a part-time geologist. 1 joined the team in April 1985. Since only the Cupar and Newburgh collections contain geological material, this account will not consider the St Andrews collection further.

Abstract (sommario):

Ad hoc' conservation status species refer to IUCN-listed plants that have been collected by botanic gardens for no immediate conservation objective. They differ from so-called conservation collections, which have usually been collected with very specific conservation objectives in mind. Information was collected for 53 ad hoc conservation status species in the Living Collection at the Royal Botanic Garden Edinburgh (RBGE). Each species was assessed for its potential value for conservation and suggested action points to improve their management for possible conservation projects in the future were given. Discussions were held with various members of staff about the current and future management of threatened plants in the collections. In common with other botanic gardens the majority of the ad hoc collections of conservation status plants at RBGE have been acquired in very small numbers, usually as one accession, frequently of cultivated origin and therefore possess little genetic diversity. Current conservation programmes for such plants are few in number and scope, and the management potential of a large number are limited. More emphasis should be placed on the educational role of these plants and on a focused programme to safeguard the survival of the most threatened species at RBGE.

This article relates the history from the nineteen seventies through the nineteen eighties of how a national plan for the care of collections was developed through the combined efforts of several national professional organizations. The pioneering work of the National Conservation Advisory Council is reviewed and its 1981 metamorphosis into the National Institute for Conservation, now Heritage Preservation, is described. How various studies and reports produced by the American Association of Museums, some in conjunction with the National and American Institutes for Conservation, helped inform a national strategy for the conservation and documentation of collections, is discussed. As the first elected chair of the board and council of the National Institute for Conservation, the author describes how the new organization contributed to the national planning process with projects like the Bay Foundation initiative to develop curriculum and train collections care specialists, Save Outdoor Sculpture (SOS!), and the Conservation Assessment Program (CAP).

Abstract (sommario):

One of the main task of Cibodas Botanical Garden (CBG) is to conserve the Indonesian plants species. Moreover, the preservation and enrichment of threatened plant collections based on IUCN red list categories became an important programme for plants conservation in CBG. The aims of this study are to inventory threatened plant collections and to review the status of CBG threatened plant collections. List of threatened plant collections was gathered from SINDATA, a system developed by CBG. The collection, was reviewed by inspecting current collections in CBG. Literature study was done to review the conservation status of the threatened plant collections. The conservation status was checked in IUCN red list website. The results shown that CBG had collected 86 species of threatened plants, which is 13 Critically Endangered (CR) species, 39 Endangered (EN) species, and 34 Vulnerable (VU) species. Critically endangered category consists of 13 species belong to 8 families and 10 genus. Endangered category consists of 39 species belong to 17 families and 34 genus. Vulnerable category consists of 34 species belong to 27 families and 28 genus. The largest collections of threatened species was genus Nepenthes, which is 16% (14 species) from the total threatened species in CBG. Furthermore, CBG had succeeded in collecting 40 species of Indonesian native plants in which Dipterocarpaceae species were dominate the collection with 7 species. These species are listed as critically endangered (3 species) and endangered (4 species).

Abstract (sommario):

Thousands of plant species are described in the planet. However, little is known about how these organisms are distributed, which is worrying, as species distribution data provide support for the development of conservation strategies. This study aimed to analyze the pattern of distribution of collections of Leguminosae species in Maranhão, determining the priority areas for collection and conservation of species. A database of Leguminosae from Maranhão was built with geo-referencing and taxonomic corrections. Then, the distribution pattern of species, collections and areas of endemism was analyzed, pointing out the main vectors of spatial pressure on this family. The South, East and fragments of the North region of Maranhão had the higher number of collections and species. The Gurupi, North and South regions of Maranhão are suggested as priority for conservation actions because they have high rates of endemism and are subjected to anthropogenic actions, and the domain Cerrado is suggested as priority due to the accelerated advance of agribusiness. This research is relevant to the knowledge of the flora of Maranhão, as it is the first to assess the distribution of Leguminosae collections in the state and suggest key areas for conservation.

Abstract (sommario):

Crop genetic resources (CGRs) are renewable resources. These resources are enriched rather than depleted by their use in research and plant breeding. Both at the time of Vavilov and, later, in the early 1970s, when concerted international efforts to collect and preserve CGRs started with the initiatives of the International Board for Plant Genetic Resources (IBPGR), CGRs were considered to be the common heritage of humankind. Now, they are widely accepted as "national heritage." Possible impacts of this nationalization on the utilization and enrichment of global crop genetic diversity and, consequently, on global food security are issues of great significance. At present, efficient management and adequate use of CGRs are more important concerns than their further exploration and collection. To increase the use of preserved CGRs in plant breeding, the formation of core collections, by selecting representative subsets from large ex situ collections of CGRs, was recommended in 1984. Since then, the core-collection strategy has been further justified as a practical approach to genetic resources management, as well as to their conservation. As a cost-saving germplasm-management strategy, the core-collection concept has considerable merit. However, the rapidly increasing popularity of core collections may undermine the genetic wealth stored in national gene banks of both developed and developing countries. Distinction is made between subsets of working collections and core collections. When a small number of CGRs is required for specific plant breeding purposes, a properly formed working collection is more useful than a representative collection. Despite the relative abundance of genetic diversity in crop plants in traditional agroecosystems, maintenance of these agroecosystems is not a realistic long-term alternative for preserving crop genetic diversity and ensuring global food security. What is needed in the "gene-rich" developing countries is the adoption of "biodiversity friendly" plant breeding and agricultural practices.Key words: crop genetic resources, core collection, germplasm conservation, in situ conservation, ex situ conservation, modern landraces.

Abstract (sommario):

The article is focused on the mobility of museum collections today in Slovakia and Czechia. The paper begins with a brief overview of the first specialist conferences to focus on the issue of collections mobility in Europe. It continues with an overview of present-day information support for sharing collections between museums in Slovakia and Czechia. It analyses the online activities of museums and cultural institutions and currently literature on the issue, as well as changes to legislation which affect the awareness of collections mobility and facilitate the process of loaning collection objects between museums. In particular, it summarises changes to the Slovak Law no. 207/2009 on conditions pertaining to the export and import of objects of cultural significance, which was amended in 2018. The conclusion includes a brief list of the most basic and, at the same time, the latest approaches to collections mobility in Europe.

Abstract (sommario):

Many crop genetic resources collections have been established without a clearly defined conservation goal or mandate, which has resulted in collections of considerable size, unbalanced composition and high levels of duplication. Attempts to improve the composition of collections are hampered by the fact that conceptual views to optimize collection composition are very rare. An optimization strategy is proposed herein, which largely builds on the concepts of core collection and core selection. The proposed strategy relies on hierarchically structuring the crop gene pool and assigning a relative importance to each of its different components. Comparison of the resulting optimized distribution of the number of accessions with the actual distribution allows identification of under- and over-representation within a collection. Application of this strategy is illustrated by an example using potato. The proposed optimization strategy is applicable not only to individual genebanks, but also to consortia of cooperating genebanks, which makes it relevant for ongoing activities within projects that aim at sharing responsibilities among institutions on the basis of rational conservation, such as a European genebank integrated system and the global cacao genetic resources network CacaoNet.

Abstract (sommario):

The ‘National Collections of Contemporary Art’ Programme of the Ministry of Culture and National Heritage constitutes an interesting case of a systemic solution to the question of financing museum collections’ purchases. Its implementation demonstrated changeability of action (both from the point of view of the applicants, and Programme’s evaluators and organizer), while at the same time the genuine assumptions were maintained, namely the support provided to the major museums, most often newly established, whose statutory goal would be and is collecting contemporary art. Turning points in the Programme, as well as the observation of applicants’ strategies while the Programme functioned served as the basis for the Programme’s evaluation, and led to replacing it with the ‘National Collections of Contemporary Art’ Programme, these, however, demonstrated failures in consistency, in particular without pointing to the final systemic solution in this respect.

Abstract (sommario):

Elizabeth Edwards, a British researcher into the relations among photography, history, and anthropology, used the term of non-collections to define numerous photographs of unidentified status which can be found in contemporary museums. They are not collector’s items, such as e.g., artistic photography or unique specimens of the first photography techniques. What she rather means are various items: prints, slides, photo-mechanic reproductions, postcards, namely objects once produced on a mass scale, with copies present in many institutions worldwide, thus being neither unique nor extraordinary. They present works from a museum collection, historic pieces of local art, or universally known works of world art. They exist in a hierarchical relation with other classes of museum objects, yet they are often pushed to the margin of curator’s practice and kept as ‘archives’, namely outside the system of the museum collection. They can sometimes be found in museum archival sections, in other instances in libraries, yet it is on more rare occasions that we come across them in photo departments. However, owing to the research into archival photographs conducted in the last decade (the studies of afore-mentioned Elizabeth Edwards and also Constanza Caraffa as well as the teams cooperating with the latter), such collections are experiencing a certain revival. Forming part of this research, the paper focuses on the collections of reproductions produced at the turn of the 20th century in museums in Toruń, Poznań, and Szczecin, which were German at the time; the reproductions later found their way to and continue being kept in Polish institutions.

Abstract (sommario):

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.

Abstract (sommario):

Effectively conserving biodiversity with limited resources requires scientifically informed and efficient strategies. Guidance is particularly needed on how many living plants are necessary to conserve a threshold level of genetic diversity in ex situ collections. We investigated this question for 11 taxa across five genera. In this first study analysing and optimizing ex situ genetic diversity across multiple genera, we found that the percentage of extant genetic diversity currently conserved varies among taxa from 40% to 95%. Most taxa are well below genetic conservation targets. Resampling datasets showed that ideal collection sizes vary widely even within a genus: one taxon typically required at least 50% more individuals than another (though Quercus was an exception). Still, across taxa, the minimum collection size to achieve genetic conservation goals is within one order of magnitude. Current collections are also suboptimal: they could remain the same size yet capture twice the genetic diversity with an improved sampling design. We term this deficiency the ‘genetic conservation gap’. Lastly, we show that minimum collection sizes are influenced by collection priorities regarding the genetic diversity target. In summary, current collections are insufficient (not reaching targets) and suboptimal (not efficiently designed), and we show how improvements can be made.

Abstract (sommario):

The indoor climate of libraries and archives is determinant for the preservation of their collections, as temperature and relative humidity can trigger other damage factors. Standards and literature recommend to perform long term monitoring to understand the climatic history where the goods were kept, instead of follow rigid and arbitrary conditions. This trend is sustainable and environmentally friendly, but adds a new duty to the overloaded staff. We present two technical advices sustained in monitoring records produced to assess the HVAC equipment and reused to preservation purposes. The first is a library collection transferred from a historic building to a new building, and the second is a deposit room supplied with de-humidificators, where the analysis evidenced a very low humidity ratio. The main conclusion is that a synergetic use of monitoring data can improve the indoor climate of the collections and reduce the energy demand for preservation.

Abstract (sommario):

This review examines the issues of ex situ conservation of Rubus L. genetic resources in the world’s genebanks and various institutions in different countries. The most urgent among the studied problems are the issues of preserving interspecific and intraspecific diversity and its sustainable utilization in breeding programs. The main attention is paid to pomologically important subgenera – raspberries Idaeobatus Focke (= Batidaea (Dumort.) Greene) and blackberries Rubus (= Eubatus Focke).Detailed information is provided on the composition and size of field, in vitro and cryogenic collections as well as seed collections. Specific features of conserving the genus’s genetic resources in collections of different types are analyzed. Information on collections of the genus preserved in the Russian Federation, unavailable in international databases, is summarized. Particular attention is paid to the collection of raspberries and blackberries held by the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR), including the history of its formation and the current state.VIR’s clonal genebank currently preserves 359 accessions of Rubus L., belonging mainly to the subgenera of raspberries (Idaeobatus) and blackberries (Rubus): 209 of these accessions are maintained in the field collection, and 150 in the in vitro collection. Raspberry cultivars developed through breeding dominate in the VIR collection – 170 accessions, among which 126 have been released by domestic breeders. Wild species are mainly represented by those collected in the Russian North – 49 clones of red raspberry (Rubus idaeus L.) and 6 of cloudberries (R. chamaemorus L.) – and in the Caucasus (35 accessions of 26 species). The data on the species diversity of the genus in Russian natural flora are presented and the strategy of replenishment, study and conservation of Rubus L. genetic resources at VIR’s genebank is discussed.

Abstract (sommario):

This paper offers an in-depth report on the best practices for the conservation and preservation of herbaria within library and museum collections. A herbarium (singular) is a collection of dried and pressed plant specimens, typically mounted onto paper and accompanied by a certain degree of recorded information. These organic specimens tend to be housed in museums or special collections libraries, where their handling can be carefully monitored and/or restricted. Each herbarium is typically one-of-a-kind and may serve as a vital primary source on human exploration, taxonomy, natural history and even amateur collection practices. A closer look at the best practices for their conservation and preservation spotlights the herbarium as a fragile, valuable and perhaps an unexpected or unusual form of “recorded information” that librarians, archivists and museum professionals may encounter or even have some responsibility over at some point in their careers.

Abstract (sommario):

In this paper, we review gene bank operations that have an influence on the global conservation system, with the intention to identify critical aspects that should be improved for optimum performance. We describe the role of active and base collections and the importance of linking germplasm conservation and use, also in view of new developments in genomics and phenomics that facilitate more effective and efficient conservation and use of plant agrobiodiversity. Strengths, limitations, and opportunities of the existing global ex situ conservation system are discussed, and measures are proposed to achieve a rational, more effective, and efficient global system for germplasm conservation and sustainable use. The proposed measures include filling genetic and geographic gaps in current ex situ collections; determining unique accessions at the global level for long-term conservation in virtual base collections; intensifying existing international collaborations among gene banks and forging collaborations with the botanic gardens community; increasing investment in conservation research and user-oriented supportive research; improved accession-level description of the genetic diversity of crop collections; improvements of the legal and policy framework; and oversight of the proposed network of global base collections.

Abstract (sommario):

AbstractIn 1975, the Missouri homesteaders Kent and Diane Ott Whealy launched True Seed Exchange (later Seed Savers Exchange), a network of ‘serious gardeners’ interested in growing and conserving heirloom and other hard-to-find plant varieties, especially vegetables. In its earliest years, the organization pursued its conservation mission through member-led exchange and cultivation, seeing members’ gardens and seed collections as the best means of ensuring that heirloom varieties remained both extant and available to growers. Beginning in 1981, however, Kent Whealy began to develop a central seed repository. As I discuss in this paper, the development of this central collection was motivated in part by concerns about the precariousness of very large individual collections, the maintenance of which was too demanding to entrust to most growers. Although state-run institutions were better positioned to take on large collections, they were nonetheless unsuitable stewards because they placed limits on access. For seed savers, loss of access to varieties via their accession into a state collection could be as much an ending for treasured collections as total physical loss, as it did not necessarily enable continued cultivation. As I show here, these imagined endings inspired the adoption of a new set of conservation practices that replicated those seen in the formal genetic conservation sector, including seed banking, cold storage and safety duplication.
