This thesis is a comparative study of the life history strategies, and in particular seed germination requirements, in Australian species of the halophyte plant genus Frankenia L. (Frankeniaceae). Frankenia is a cosmopolitan genus that occurs in Mediterranean, semi-arid, and arid regions on distinctive soil types commonly on saline, sodic or gypseous soils in habitats such as coastal cliffs, and on the margins of salt lakes, salt-pans and saltmarshes (Summerhayes 1930; Barnsley 1982). The plants are small shrubs or cushion-bushes with pink, white or pale purple flowers, and salt-encrusted

Over the past several decades, cell size and its resulting effects on tissue and organ function, as well as on its overall ability of the animal to perform complex tasks, has been studied extensively. Neuronal size (diameter of individual neurons) could have an influence on intelligence, brain capacity, and ability to perform complex behavioral tasks. Furthermore, there appears to be an increase in number of neurons with an increase in brain size in vertebrates. In insects, increased neuron number has also been correlated with more complex behavior. In this thesis, I test the hypothesis that t

Streszczenie:

Seed size is regarded as a functional trait with very important consequences for the fitness of plant species. Seedlings emerging from larger seeds are more competitive but are more costly to produce than seedlings from smaller seeds. Seed size is also a trait with transgenerational effects, affecting both the fitness of the parent as well as that of the offspring. Theory on the evolution of offspring size predicts an optimum balance between size and number, seen from the parent's perspective; while empirical studies often show selection for larger seeds, seen from the offspring's perspective.

It is becoming increasingly important to improve the yield of seed crops to feed an expanding population and, more recently, to cope with additional strains on food-oriented agriculture posed by biofuel production and global climate change. One strategy to increase yield is to increase seed size. However in nature, due to the limited resources of the mother plant, an enlarged seed size is often associated with a concomitant reduction in seed number. Using the model plant Arabidopsis thaliana, a biotechnological approach to increase seed size through the modification of the triploid endosperm o

Pressure distributions on both airfoil top and bottom surfaces in the chord-wise direction near the gap were recorded for these airfoils.

Seeds from the open-pollinated 4N x 2N cross were primed in solutions of distilled water, polyethylene glycol '8000' (PEG), and potassium nitrate (KNO₃), or left untreated; treated seeds were subsequently dried for either 1 or 7 days.

It has long been evident that genome size is not an accurate measure of organismal complexity. This paradox was “solved” with the discovery of nonfunctional and selfish DNA in the 1970s. However, emerging from this explanation was an enigma of complexity. Neither neutral nor adaptive models can account for all genome size variation across the tree of life. An organism with intraspecific variation is needed to investigate the functional role of genome size differences. Here I use different populations of the seed beetle, Callosobruchus maculatus, with a known intraspecific genome size variation

Maintaining global food security in the presence of a growing food demand and climate change will require an improved understanding of the genetic basis of crop yield components, and their response to environmental stress conditions, such as drought.

This model is used to define and understand the process of determining the optimum number of increments that should be used in forming a composite.

A trade-off between seed size and seed number is central in seed ecology, and has been suggested to be related to a trade-off between competition and colonization, as well as to a trade-off between stress tolerance and fecundity. Large seeds endure hazards during establishment, such as shading, drought, litter coverage and competition from other plants, better than do small seeds, due to a larger amount of stored resources in the seed. Small seeds, however, are numerous and small-seeded species are therefore more fecund. Moreover, a pattern with small-seeded species being associated with open

Young children are limited in their usage of comparative adjectives and ordinal numbers, typical ways of describing ordinal relationships.

Additionally, linguistic demands were reduced by using family-role terms as size designators. Experimental manipulations included variations in scale size and in the complex

Streszczenie:

Experiments were conducted in controlled and field conditions to determine the effect of seed size, a fungal pathogen (Colletotrichum coccodes), and soybean interspecific competition on the population dynamics of Abutilon theophrasti (velvetleaf). Seed size differences among ten individual A. theophrasti plants significantly (P < 0.001) affected seed germination and dormancy. Higher seed viability (98%) was observed among seeds having a weight above 6.0 mg. The response of A. theophrasti plants that originated from two extreme seed size groups (small <7mg and large >12mg) to the pathogen, C. c
