Testo completo

Abstract (sommario):

Melampyrum sylvaticum (small cow-wheat) is a hemiparasitic annual of boreal-montane regions of Europe. The Species Action Plan recommended that in addition to protecting extant populations, by 2010 there should be an additional five populations that have been created with the aim of enhancing greater genetic diversity of the species. Consequently this project was set up in order to provide the ecological knowledge required to meet such targets. There are various management options available to conservationists looking to prevent Melampyrum sylvaticum’s extinction from the UK but from the results of this project it is clear that some methods have drawbacks that should preclude their use. Population augmentation with seeds from other populations is not advised due to the risk of genetic ‘swamping’ or outbreeding depression. Seed amplification would avoid these problems but may introduce different complications by artificially promoting certain genotypes within a population. Population expansion by mimicking ant dispersal is recommended as a way of minimizing density dependent mortality in larger populations but is not suitable in smaller populations. Seed translocation to unoccupied sites is therefore, the best option but the exact details of seed-sourcing and sowing should be guided by the results of the Species Recovery Project in order to avoid predicted limitations. The long-term outlook for M. sylvaticum will depend entirely on whether populations can be created that operate as part of a functioning ecosystem (including pollinating and seed-dispersing insects) with enough demographic and genetic stability to survive predicted climate change.

Testo completo

Abstract (sommario):

The Swede, Carl Linnaeus (1707-1778), introduced an artificial " Sexual System " of plant classification in 1735, and a binomial system of nomenclature in 1753. They made plant identification much easier. The Linnaean period in Britain lasted from 1760 until [1810-]1830. It is demonstrated that it was during this period that it was first recognised that an unusually high number of rare plants grow in Upper Teesdale. Most of the rare plants of the then very remote Upper Teesdale were discovered shortly after 1783 by William Oliver (1760-1816), alone. He was a surgeon and part of a medical dynasty. How he became a botanist, with his medical background, is examined in detail. He trained at Edinburgh but did not do botany. However, he knew John Hope, the Professor of Botany. Hope was one of only two people teaching the Linnaean system in Britain at this time. The appearance of Linnaean floras of Britain in English from the 1770's onwards made field botany accessiblet o anyone. Previously complex natural systems of plant classification and the use of Latin had restricted access. How Oliver's discoveries were made known is examined in detail. It involved Rev. John Harriman (1760-183 1) who was influenced by the Linnean Society of London, formed in 1788, and the Linnaean English Botany which began in 1790. H-e wanted to become a Fellow of the Linnean Society. James Edward Smith was President of the Linnean Society and an author, with James Sowerby, ofEnglish Botany. IV alic, ,j Lrf Edward Robson (1763-1813), a Quaker botanist and already an Associate of the Linnean Society, and his compilation: Plantae rariores agro Dunelmensi indigenae of 1798, and John Binks (1766-1817), an artisan botanist. Medicine made botanists of both Harriman and Binks, as well as Oliver. Linnaeus influenced the teaching of materia medica (the plant simples).

Abstract (sommario):

The Orchidaceae is characterized by a remarkably diverse range of life forms and some of the most highly specialized interactions with soil fungi and insect pollinators found in the flowering plants. Many species are rare or threatened with extinction either directly through loss of habitat or over-collection or, indirectly through debilitation or loss of mycorrhizal association or pollinator capacity. Australian temperate terrestrial orchids represent one of the most threatened groups in the Australian flora with many taxa clinging to existence in urban and rural bushland remnants, road verges and unprotected bushland. The aim of this study is to research and develop integrated conservation based on critical aspects of terrestrial orchid biology and ecology, towards the recovery of the rare and endangered Western Australian terrestrial orchid Caladenia huegelii. This study identified key aspects involved in an integrated conservation approach and research focused on conservation genetics, mycorrhizal interactions and in situ and ex situ conservation strategies for this species. Using polymorphic microsatellite molecular markers, high levels of genetic diversity were found within remnant populations of C. huegelii, while weak differentiation was observed among populations over the species geographic range. These results indicate historic genetic exchange between C. huegelii populations, a possible consequence of the sexually deceptive pollination strategy and the capacity for widespread seed dispersal. Symbiotic germination studies revealed compatibility barriers to C. huegelii germination with the orchid possessing a highly specific orchid-mycorrhizal association relative to common sympatric congeners. These results were reflected in a phylogenetic analysis of DNA sequences, revealing C. huegelii associates with only one endophyte species within the fungal family Sebacinaceae across its geographic range. Large scale in situ seed baiting demonstrated that endophytes compatible with C. huegelii were limited in distribution relative to common and widespread orchid species, a feature for C. huegelii that may be a major contributing factor in limiting the distributional range of the species. Detailed, within site seed baiting methods identified hotspots for mycorrhizal fungus compatible with C. huegelii that were unoccupied by the orchid. These mycorrhizal hotspots where used to investigate the effect of endophyte presence on survival of transplanted mature plants and seedling outplants. The in situ survival of glasshouse propagated seedlings was further optimized by incubating seedlings in growth containers before transfer to soil and outplanting seedlings in their second growing season. The findings of this study will substantially advance the recovery of C. huegelii and provide benchmark knowledge for similar projects with other rare and threatened terrestrial orchid species.

Abstract (sommario):

To effectively conserve the gene pool of protected plants ex situ, a wide range of methods and approaches is used, each of which has its own advantages and disadvantages. To date, considerable experience has been gained in the preservation of plant genetic resources, which are important mainly for the agricultural sector, using different temperature regimes; gene banks have been created all over the world. Unfortunately, cryopreservation of seeds and various other plant material is successfully used mainly for agricultural crops, and experiments to preserve the gene pool of rare and endangered plant species are not so widespread. It is necessary to investigate the possibility of sustainable reproduction of the gene pool of certain rare and endangered species. The use of microclonal reproduction of protected plants is an additional way to preserve their gene pool and a prerequisite for the repаtriation of species that are disappearing in nature. The development of effective methods of microclonal reproduction is the basis of work on the creation of in vitro genetic banks of rare and endangered plant species, as well as one of the promising directions for the conservation of biodiversity in general.

Testo completo

Abstract (sommario):

Active sand dunes in Kobuk Valley National Park are a regionally rare and ecologically distinct landscape feature occurring within the northern boreal biome. The sand dunes harbor a rich diversity of plants, including several rare and disjunct species and the endemic Kobuk locoweed (Oxytropis kobukensis). Pollinators associated with these dune plants have not been studied in Kobuk Valley, despite their essential role in transporting pollen which many plants rely on for successful reproduction. In order to gain a better understanding of pollinator diversity and plant-pollinator associations in this unique ecosystem north of the Arctic Circle, we conducted surveys of bees (Hymenoptera: Anthophila) and syrphid flies (Diptera: Syrphidae) in several places along the Kobuk River and in two active dune areas, the Hunt River Dunes and the Great Kobuk Sand Dunes, in late June-early July of 2017 and 2019. We used active and passive collecting methods to sample pollinators at 21 different sites and along five walking transects, and we documented plant associations for net-collected specimens. In all, we collected 326 bees and 256 syrphid flies, representing 27 and 37 taxa, respectively. The most abundant and widespread species collected among syrphid flies were Lapposyrpus lapponicus and Eristalis obscura. For bees, three soil-nesting solitary species, Andrena barbilabris, Megachile circumcincta, and Osmia tarsata made up 60% of the total bee catch. Dryas integrifolia, a widespread plant on the dunes, hosted the highest number of bee and syrphid fly taxa (13 and 20, respectively). Bumble bees (Bombus) and megachilid bees (Megachile, Osmia) favored several plants in the Fabaceae family, while mining bees (Andrena) were abundant on Salix species (willow). A high diversity of syrphid flies were collected on the composite Packera ogotorukensis, and Salix species. Our collections indicate that the endemic Oxytropis kobukensis was primarily visited by the mason bee, Osmia tarsata (44% of all visitors) and the leafcutter bee, Megachile circumcincta (27%). Bumble bees (genus Bombus) made up another 13% of all visitors to this plant. Our study confirms that the active sand dunes in Kobuk Valley provide an ecologically unique habitat both for plants and their associated insect pollinators. For example, many of the solitary bees living in the dunes rely on deep sands for nesting and thus are limited in their distribution across Arctic and boreal landscapes.

Abstract (sommario):

This report presents the results of vegetation monitoring efforts in 2020 at Fort Laramie National Historic Site (FOLA) by the Northern Great Plains Inventory and Monitoring Network (NGPN) and the United States Geological Survey (USGS). This was the tenth year of combined monitoring efforts. Crew members from USGS visited 9 long-term monitoring plots to collect data on the plant communities at FOLA. This work is part of a long-term monitoring effort designed to provide a better understanding of the condition of the vegetation community at FOLA and how it changes over time. USGS staff measured species richness, herb-layer height, native and non-native species abundance, ground cover, and site disturbance at each of the nine plots. In plots where woody species were present, tree regeneration, tall shrub density, tree density, and woody fuel loads were also measured. Data collection at seven plots was incomplete, where only point-intercept, site disturbance, and invasive species presence data were collected, while in two plots the previously listed protocols as well as the quadrat protocol were performed. In 2020, the monitoring crews identified 44 unique plant species in 9 monitoring plots. Of those species, 19 were exotic species. In a majority of plots (5 of 9), there was a greater percent of native species cover compared to exotic species cover. However, exotic plants were found at every plot in FOLA. No rare species were observed during our surveys
