Wild rice (Zizania Palustris) seed biology: germination under a changing climate
… will impact manoomin/psiɳ germination and how seed traits influence germination and early seedling growth. Specifically, I investigated how differences in winter duration, temperature, and water levels influence overall seed germination and germination rates (time to germination). In addition, …

Seed biology of a recently introduced species, Myoporum laetum in comparison to a successful invasive alien, Acacia cyclops, in the southwestern Cape, South Africa
… evaluated, by comparing various aspects of its seed biology with those of another bird-dispersed alien, Acacia cyclops which is a successful invader in this region. M. laetum has higher annual seed production, but lower soil-stored seed banks than A. cyclops. Both experience high seed predation, …

Seed morphology, dormancy and germination of South-West Australian Ericaceae
… contains species with difficult to germinate seeds, including many species with deep intractable dormancy. A better understanding of seed biology and species specific dormancy, and germination mechanisms is required to overcome these difficulties. Land clearing, salinity and disease has …

Integrated management of the invasive weed, cut-leaved teasel (Dipsacus laciniatus L.) along a Missouri highways
… and undisturbed areas. Studies regarding seed biology, detection, and control measures were conducted to improve teasel management along a four mile section of Highway interstate 70 in central Missouri. Seed characteristic such as viability after flowering, emergence pattern and …

The comparative ecology of Minuartia verna (L.) Hiern and Thlaspi alpestre L. in the southern pennines, with special reference to heavy metal tolerance.
… and genecology of the species, their population biology and dynamics in the field and their responses to competition from other species. Both field and laboratory studies confirmed that the two species were highly tolerant of the heavy metals lead, zinc and cadmium. Short- and long-term solution …

The Role of Temperature in the Seed Germination Ecology of Mountain Springs and Fens
… groundwater. This thesis studies their seed ecology, focusing on the interaction between environmental temperature and germination. To this end we conduct laboratory germination experiments with calcareous spring fen species to characterize the temperature dimension of the germination …
