Question: We asked whether a desert ant population and a community of heteromyid rodents select Dithyrea californica seeds in relation to their size, frequency of seed sizes, and absolute density and thus have the capacity to influence natural selection on seed size. Hypothesis: Following the predictions of optimal diet theory, we hypothesized that seed predators will prefer to prey upon larger...

OBJECTIVE The aim of this study was to investigate the effects of simultaneous supplementation of laying hens with alpha-linolenic acid (ALA) resources (flax, perilla, and Eucommia ulmoides [E. ulmoides] seeds) and eicosapentaenoic acid/docosahexaenoic acid (EPA/DHA) resources (Schizochytrium sp.) on egg quality and n-3 polyunsaturated fatty acids (PUFA) profile. METHODS Dietary treatments we...

OBJECTIVE The purpose was to monitor implanted seeds and to determine factors contributing to seed migration after permanent prostate brachytherapy. METHODS Sixty-two consecutive patients with Stage 1 prostate cancer who underwent brachytherapy with (125)I seeds between February 2008 and May 2009 were studied prospectively. On post-operative days 1, 7 and 30, scintigraphy was added to convent...

BACKGROUND AND AIMS Mimetic seeds simulate the appearance of fleshy fruits and arilled seeds without producing nutritive tissues as a reward for seed dispersers. In this strategy of seed dispersal, seeds may remain attached to the mother plant for long periods after maturity, increasing their availability to naïve seed dispersers. The hypothesis that seed coat impermeability in many tropical Fa...

BACKGROUND The purpose of this study was to investigate the differences in the dosimetric advantage of using intraoperatively built custom-linked (IBCL) seeds between permanent iodine-125 (I-125) seed implantation (PI) alone and PI followed by external-beam radiation therapy (EBRT) for prostate cancer. METHODS We reviewed the records of 62 patients with localized prostate cancer who received ...

Impatiens seeds treated with the ethylene biosynthetic precursor 1-aminocyclopropane-1-carboxylic acid (ACC) had reduced times to radicle protrusion and seedling emergence. Sixty hours after imbibition, 68% more seeds showed radicle protrusion on media containing 0.1 or 1.0 mM ACC compared to seeds germinated on water alone. Subsequently, ACC was effectively “loaded” into impatiens seeds using ...

Question: Are seed mass and shape related to persistence in the soil seed bank among 54 species of the Israeli flora? Search method: Persistence was determined by soil seed bank investigations in which the fraction of non-germinated viable seeds was regarded as the persistent soil seed bank. When seedling emergence had ceased but before new seeds were shed, all soil from the upper 5 cm of 120 q...

The dormancy and seed germination of Tamarindus indica (L) was studied. This involved the usage of some dormancy-releasing methods and the influence of oven dry heat treatments on the seeds. The preliminary germination tests on fresh and air-dried seeds showed low percentage germinability (10-20%). The seeds are known to have high socio-economic value most especially in the savanna regions of t...

Seeds from natural populations of fierce thornapple and velvetleaf collected in a corn-growing area in central Spain were incubated at a range of constant temperatures and water potentials to model the progress of germination on the basis of the accumulation of hydrothermal time. Previous to the germination tests, the seeds were treated in two different ways: (1) dark storage under dry conditio...
