The Agavaceae and Nolinaceae, as other plant families, have been affected by the destruction and modification of their habitats and by selective extraction with commercial purposes of some of their species. This has generated that 48 species of Agavaceae and Nolinaceae have been included in the list of Mexican plants in risk of extinction (NOM-059-ECOL-l 994), and two of them (Agave parviflora and Agave victoriae-reginae) are listed in the appendices of CITES. There are 30 Protected Natural Areas that conserve in situ at least one species of the Agavaceae or Nolinaceae. The ex situ conservation is done in 38 Botanical Gardens, 22 of them include in their collections at least one species of these families. There are also eight commercial nurseries that have started the propagation by seed of 12 species, mainly from the genus Agave. Case studies on Agave victoriae-reginae, Beaucarnea recurvata and Yucca schidigera, are also analyzed.

Two major collecting institutions in Australia, the Australian Museum (Sydney) and Museums Victoria (Melbourne), are currently undertaking large-scale anoxic rehousing projects in their collections to control conservation issues caused by pyrite oxidation. This paper will highlight the successes and challenges of the rehousing projects at both institutions, which have collaborated on developing strategies to mitigate loss to their collections. In 2017, Museums Victoria Conservation undertook a survey with an Oxybaby M+ Gas Analyser to assess the oxygen levels in all their existing anoxic microclimates before launching a program to replace failed microclimates and expand the number of specimens housed in anoxic storage. This project included a literature review of current conservation materials and techniques associated with anoxic storage, and informed the selection of the RP System oxygen scavenger and Escal Neo barrier film from Mitsubishi Gas Chemical Company as the best-practice products to use for this application. Conservation at the Australian Museum in Sydney was notified of wide-scale pyrite decay in the Palaeontology and Mineral collections. It was noted that many of the old high-barrier film enclosures, done more than ten years ago, were showing signs of failing. None of the Palaeontology specimens had ever been placed in microclimates. After consultation with Museums Victoria and Collection staff, a similar pathway used by Museums Victoria was adopted. Because of the scale of the rehousing project, standardized custom boxes were made, making the construction of hundreds of boxes easier. It is hoped that new products, like the tube-style Escal film, will extend the life of this rehousing project. Enclosures are being tested at the Australian Museum with a digital oxygen meter. Pyrite rehousing projects highlight the loss of Collection materials and data brought about by the inherent properties of some specimens. The steps undertaken to mitigate or reduce the levels of corrosion are linked to the preservation of both the specimens and the data kept with them (paper labels). These projects benefited from the collaboration of Natural Sciences conservators in Australia with Geosciences collections staff. Natural Science is a relatively recent specialization for the Australian conservation profession and it is important to build resources and capacity for conservators to care for these collections. This applied knowledge has already been passed on to other regions in Australia.

Developed by the cosmetics industry, silicone-based solvents such as Cyclomethicone D4 and D5 and emulsifiers Velevsil Plus and KSG 350Z have found useful applications in museum conservation after being pioneered by Richard Wolbers to safety clean acrylic paint films. These products’ unique properties are also applicable for cleaning of natural science specimens. Silicone solvents are volatile and will completely evaporate away from surfaces. They have very low polarity and cannot not solubilise fats or oils, such as natural preen oils found in feathers. Low viscosity gives them the ability to flood a porous surface, such as bone, protecting it from absorbing chemicals and soiling during cleaning. Velevsil Plus and KSG 350Z provide the desirable ability to form an emulsion with water, and or solvents in a silicone based solvent carrier, allowing for the strictly controlled application of water or solvent solutions to the surface of a specimen. This poster will present case studies from the Otago Museum (Dunedin, New Zealand) and Museums Victoria (Melbourne, Australia) investigating the use of these products in cleaning natural science specimens. The experiments include the removal of an aged wax and shellac coating from a Moa (Dinonris sp.) skeleton, the removal of acrylic coatings on extremely moisture sensitive pyritized fossils, and the cleaning of soiled feathers and fur. Issues around sourcing and shipping these specialised products to Australasia will also be discussed. The successful application of paintings conservation techniques to scientific specimens demonstrates the benefits of collaboration between specialisations in conservation for developing new techniques for caring for our collections.

Horticultural science has an essential role to play in the conservation of rare plants, but to date, most horticultural research in this field has taken place on an informal rather than experimental basis. Plant conservation as a scientific and practical discipline would benefit greatly from applying the more rigorous approach characteristic of commodity-oriented horticultural research. In turn, the profession of horticultural science has a great deal to gain by participating more actively in plant conservation programs. Benefits include an influx of new ideas, new people, and new resources. Some of the traditional research fields within horticulture that are directly relevant to rare plant conservation include: seed technology, propagation and tissue culture, nutrition, growth regulation, soil management, and protection from pests and diseases. Three case studies illustrate various ways in which the theory, technology, and knowledge base of horticulture can be applied to plant conservation. They include the rare plant propagation program at Bok Tower Gardens, Lake Wales, Fla.; mountain meadow revegetation projects in Mount Rainier and Olympic National Parks in Washington; and research activities of the recently established Georgia Plant Conservation Alliance.

Energy efficiency is extremely important to all organisations, especially those that are energy intensive. Detailed studies to establish, and investigate, energy balances for specific plant departments or items of process equipment have been carried out. The energy audit of the industry (Indo-German Tool Room, Indore) has been done. It has been concluded that total energy saving potential of 1,28,560 KWH per year is possible by implementing the recommendations. Hence achievable saving is 13.85% of total annual electricity consumption. The total savings Rs.7,71,360/- per year with initial investment of Rs.12,79,000/-.

Habitat loss and fragmentation are key biodiversity indicators of the Montreal Protocol for monitoring progress towards ecologically sustainable forest management. Over the last 15 years, an array of landscape metrics have been developed as spatial measures of habitat loss and fragmentation. However, most metrics require rigorous empirical testing if they are to provide scientifically credible information to managers and policy makers. We present a synthesis of three Australian case studies for developing Montreal Indicator 1.1e, fragmentation of forest type, each representing different levels of landscape modification: St Mary State Forest, south-east Queensland; Tumut, southern New South Wales; and the Central Highlands, Victoria. Collectively, the studies found that no single landscape metric captured the response of the target species and fauna assemblages, or served as a reliable ecological surrogate for the conservation of a large set of species. Rather, species demonstrated a diversity of responses to habitat loss and fragmentation. Fragmentation effects were more important for the Tumut study, but not important for the Central Highlands study. Stand-scale habitat variables and area of suitable habitat were dominant explanatory variables for the St Mary study. Differences in observed response are partly explained by: (i) differences in landscape structure, particularly the proportion of preferred forest habitat remaining; (ii) differences in the ecology of target species; and (iii) the insensitivity of the landscape measures. Based on the outcomes of the three case studies, we propose principles for developing landscape surrogates for conserving biodiversity in Australia's eucalypt forest landscapes.

AbstractIntroduced into Lake Victoria in the 1950s, the Nile perch has gained fame for prompting rapid regional economic growth and for driving scores of endemic fish species into extinction. This study uses oral and archival data to trace the historical development of the Nile perch fishery on Lake Victoria. Particular emphasis is placed on local responses and adaptations to (1) the Nile perch itself; (2) the abrupt integration of the Lake Victoria fishery with the global economy; and (3) the ecological changes that the Nile perch has precipitated. I also attempt to situate Lake Victoria's history in the larger debate about environment and African livelihoods. Because so much of Lake Victoria's species diversity has been lost within one generation – biologist E. O. Wilson (1992) has called this process ‘the most catastrophic extinction episode of recent history’ – the lake is an ideal case study with which to examine ‘local’ perceptions of biodiversity. The data suggest that species diversity is important and highly resolved in the worldviews of Lake Victoria's fishermen; yet, although the will for conservation is present, poverty obstructs its realization. These findings are discussed in relation to other work on indigenous environmental knowledge and ecological ethics. I argue that ‘intrinsic’ valuation of species diversity and ecological processes may be more widespread in rural societies than has traditionally been assumed by natural and social scientists, and that the preponderance of social studies highlighting oppositions between Western science and ethno-science, and between conservation concerns and local livelihoods, may have blinded us to synergies between them. More effort is needed to understand fully the nuances in these complex local ecological worldviews, perhaps via ‘social histories of extinction’ that explore the local consequences of species loss.

This thesis advances plant biodiversity knowledge in three separate bioregions, Micronesia, the Queensland Wet Tropics, and South Australia. A systematic treatment of the endemic flora of Micronesia is presented for the first time thus advancing alpha taxonomy for the Micronesia-Polynesia biodiversity hotspot region. The recognized species boundaries are used in combination with all known botanical collections as a basis for assessing the degree of threat for the endemic plants of the Palau archipelago located at the western most edge of Micronesia’s Caroline Islands. A preliminary assessment is conducted utilizing the IUCN red list Criteria followed by a new proposed alternative methodology that enables a degree of threat to be established utilizing existing data. Historical records and archaeological evidence are reviewed to establish the minimum extent of deforestation on the islands of Palau since the arrival of humans. This enabled a quantification of population declines of the majority of plants endemic to the archipelago. In the state of South Australia, the importance of establishing concepts of endemism is emphasized even further. A thorough scientific assessment is presented on the state’s proposed biological corridor reserve network. The report highlights the exclusion from the reserve system of one of the state’s most important hotspots of plant endemism that is highly threatened from habitat fragmentation and promotes the use of biodiversity indices to guide conservation priorities in setting up reserve networks. In the Queensland Wet Tropics the thesis achieves two additional outcomes. A localized pilot study test the accuracy of plant DNA barcodes to estimate species richness. Species richness estimations were performed with high accuracy suggesting the suitability of the approach in poorly known floras where the identity of samples is known or from samples in a cryptic life stage that are difficult to identify. The methodology is promising for areas of the world, such as the tropics, that contain a high percentage of undescribed or poorly known taxa. In addition, a large dataset from northeast Queensland was utilized to assess broad scale patterns of phylogenetic diversity. A linear relationship between phylogenetic diversity and genus richness is found to have high statistical support suggesting that taxon richness is an accurate predictor of hot spots of evolutionary history. When the affects of taxon richness are removed through linear regression however, a strong biogeographic pattern is unveiled. Sites with higher phylogenetic diversity than expected based on genus richness are best explained by having a lower percent of Gondwanan or endemic Australian elements of the flora. These sites have a higher percentage of Indomalayan or other foreign lineages that dispersed to Australia and are more frequent in the lowland rainforest areas below 200 meters. Phylogenetic diversity is shown to be effective at unraveling broad scale patterns of evolutionary history at the biome scale, which may prove useful for justifying the preservation of not just species but assemblages of species that represent different epochs of the earth’s evolutionary history.

Abstract Biotic resistance to plant invasions takes many forms: consumption by native herbivores, competition with native plants and infection by native pathogens. But how often does biotic resistance prevent the damaging monocultures that typify the most problematic plant invaders, and how often is biotic resistance overwhelmed by the direct and indirect impacts of human activities? This chapter attempts to answer these questions, drawing on the long history of research into biotic resistance. We first briefly describe the major forms of biotic resistance to exotic plant invasions as an antecedent to other, more detailed chapters on competition, herbivory and pathogens. We then describe a new neutral model where variance in disturbance promotes invasions over the short term, but over longer timescales only propagule pressure drives invasions. These findings are a cautionary tale; pending increases in global trade and travel, particularly to the tropics, may provide the prerequisite disturbance and propagule pressure needed to ultimately stoke further invasions. Finally, we highlight case studies where invasions have been mitigated by restoration of biotic resistance from native herbivores and competitors. These studies provide strong empirical support that conservation of native biodiversity can be a nature-based solution to some invasions, although it remains to be seen if climate change will alter these effects over longer timescales.

AbstractAn understanding of the different microbial constellations or microbiomes, which every habitat and every organism harbor, will be the key to addressing many of the challenges humanity will face in the twenty-first century. Such comprehension could launch several innovations relating to natural and cultural capital, including historical and artistic heritage. In relation to cultural heritage, microorganisms are mainly known through their role as deteriogens, but the features creating damage can be exploited positively, attaining more sustainable restoration strategies, in accordance with the principles of compatibility and retreatability deriving from reflections on the Cultural Heritage inspired by the Charter of Venice (International charter for the Conservation and restoration of monument and sites (the Venice Chart 1964). In: ICOMOS, IInd International Congress of Architects and Technicians of Historic Monuments, 1964) onwards. In this article, we show a series of case studies, using both wild-type microorganisms and plant-based extracts, providing a comprehensive proof of concept of the feasibility of biotechnological solutions for a more sustainable restoration strategy, to replace the products in use which are often dangerous for operators, aggressive for works of art and no longer compatible with the environment. The overview of the case studies presented, many of which are still unpublished, responds to the need to go beyond the state of the art and has entirely sprung from suggestions by restorers, interested in learning about potential innovations and strongly determined to introduce non-toxic products in their daily work. In this perspective, the case studies dealt with two topics: bio-cleaning and disinfection. Noteworthy results were obtained on a platform of different types of artworks and different materials with compatible, harmless and selective products.

Abstract Critical (choked) flow is a highly concerning phenomenon in safety analysis for nuclear energy. During an accident, the radioactive aerosol in nuclear power plant (NPP), which is hazardous for the environment, may be released accompanying the fluid discharge. Consequently, the discharge mass flow rate prediction is crucial for engineering design and emergency response in case of nuclear accidents. Unfortunately, the critical flow is difficult to predict especially when two-phase flow exists. Developing a more accurate model for critical flow is an essential requirement to the system thermal-hydraulic (STH) codes (e.g., RELAP5, TRACE, and ATHLET, etc.) for nuclear safety analysis. The accuracy is based on a deeper understanding of the complex phenomenon of critical flow. One of the difficulties concerned with the mathematical modeling of the two-phase critical flow is the complexity of the transfer phenomena at the interface. Normally, an interfacial drag law and a virtual mass force were used to quantify the momentum transfer between the phases in the STH codes. The present study is concerned with the effect of virtual mass force on phase separation during the acceleration of a two-phase mixture. Virtual mass represents real physical effects and it can be regarded as induced inertia on the dispersed phase which is accelerating relative to the continuous phase. It has been verified that the virtual mass acceleration is objective, and the consideration of it in the two-phase flow simulation can improve the numerical stability and efficiency. Therefore, a variety of objective forms of virtual mass acceleration were derived in the last fifty years. But the influence of virtual mass force on the two-phase critical flow was seldom concentrated on owing to the lack of suitable critical flow models for studies in detail. This study is based on a developed two-phase critical flow model based on the separate conservation equations of mass, momentum, and energy for each phase. Several typical models of virtual mass force are selected and their influences on the accuracy of critical flow predictions will be studied in some detail. Furthermore, the critical flow that happened in the NPP accident scenarios may go through several flow regimes such as subcooled flow, bubbly flow, slug flow, and annular flow, etc. The impact of virtual mass force on these different stages of critical flow is another topic of this study. The results of this study can benefit a further understanding of virtual mass force, especially its influence on critical flow, and will contribute to the development of a more accurate two-phase critical flow model.
