Reproductive biology and ex situ conservation of the genus Restrepia (Orchidaeae)
… of this investigation was, therefore, to add to existing knowledge so that the resultant data could be used to facilitate ex situ conservation initiatives. A detailed electron microscopy study (SEM) of the floral organs was performed. This confirmed the structure of the dorsal sepal and lateral …

Conservation Genetics of Narrowly Distributed Annual, <em>Erythranthe discolor </em>(Phrymaceae), in the Southern Sierra Nevada
… 20-80% of occurrences are under threat. Using conservation genomic techniques and analyses, this study aims to determine population structure and diversity metrics of E. discolor for in situ and ex situ conservation recommendations. In addition, baseline flower color information was taken …

Mediterranean Wild Edible Plants: Diversity, Conservation and Potential Use
… threatens their cultivation. In this context, reintegrating WEPs into agricultural systems can contribute to dietary diversification and strengthen crop resilience. This PhD thesis aims to explore the potential of Mediterranean WEPs in relation to the impacts of climate change, through an …

Unlocking the genetic diversity of the undomesticated rice relative Oryza longistaminata
… hybridization with O. sativa, as well as the expense and difficulty of identifying which O. longistaminata accessions carrying useful genes. Breeding programs also rely on thorough ex-situ conservation of O. longistaminata, which enables long-term access to germplasm for breeders and other …

Predicting suitable areas for cultivation and conservation of the baobab tree and investigating superior sources of planting material
… A decline in baobab populations due to overexploitation and/or changes in climate could have a significant negative effect on African livelihoods. Therefore, it is important to determine potential strategies for conservation and cultivation. The present and potential future distributions of …

An Investigation of Seed Longevity and Antioxidant Changes of Conserved Barley Germplasm
Seed longevity is crucial for the sustainable ex situ conservation of germplasm in genebanks, yet its reliable assessment remains a significant challenge. This research was conducted to predict the longevity of a diverse barley (Hordeum vulgare L.) germplasm collection comprising cultivated and …

Demographic and Genetic Consequences of Small Population Size in Remnant Populations of Arabis georgiana Harper (Georgia Rockcress)
… occurring "native" plants and plants grown ex situ and subsequently restored to one of the largest remaining populations of A. georgiana, and 2) a preliminary analysis of population genetic structure in remnant populations across the species' range was performed. In addition to updating …

A multi-scale exploration of the drivers and implications of germination strategy in Australian alpine plants
… seeds to germinate, establish and reproduce in situ, or after dispersal to new sites. The effects of climate change on regeneration from seeds may be influenced by intrinsic factors such as seed longevity (how long seeds remain viable and able to germinate after dispersal), or germination …

Biology and conservation status of Juniperus macrocarpa Sm. in Sardinia
… well as to achieve results useful to support in situ and ex situ conservation actions. In particular, the specific aims of the thesis were: (1) to analyse morphological variation in seeds of Mediterranean Juniperus taxa (at inter- and intraspecific level) and morphometric differences in J. …

Assessing species-specific reproductive variation to inform assisted reproductive technologies for Canadian snakes
… livestock, are increasingly incorporated into conservation mating programs for species-at-risk. Species-specific insights on reproductive biology, including seasonal variation and endocrine function, improve ART outcomes. Despite representation in many zoological collections, snakes are …
