Growth of the eye lens: II. Allometric studies
PURPOSE The purpose of this study was to examine the ontogeny and phylogeny of lens growth in a variety of species using allometry. METHODS Data on the accumulation of wet and/or dry lens weight as a function of bodyweight were obtained for 40 species and subjected to allometric analysis to examine ontogenic growth and compaction. Allometric analysis was also used to compare the maximum adult...
متن کاملAn allometric model for seed plant reproduction
An allometric framework is used to construct a model for seed plant annual reproductive biomass based on standing leaf, stem and root biomass. According to this model, the scaling of reproduction is governed by numerous taxon-specific scaling exponents and constants that reflect the allometry of vegetative biomass partitioning. Although this allometry cannot be predicted a priori, the model acc...
متن کاملAllometric scaling of plant life history.
Plant mortality and birth rates are critical components of plant life history affecting the stability of plant populations and the ecosystems they form. Although allometric theory predicts that both plant birth and mortality rates should be size-dependent, this prediction has not yet been tested across plants ranging the full size spectrum. Here we show that both population mortality and popula...
متن کاملALLELOPATHIC EFFECTS OF Artemisia monosperma DEL. ON GERMINATION AND SEEDLING GROWTH OF SOME RANGE PLANT SPECIES
Artemisia monosperma is observed to be as one of the first species to dominate disturbed sand dunes in Saudi Arabia. Despite its importance as a sand stabilizer, it has no forage value. It is feared that this species may arrest the natural succession of vegetation. A series of controlled environment experiments was conducted to study the potential allelopathic effects of A. monosperma on germin...
متن کاملAllelopathic Effects of Goldenrod Species on Turnover in Successional Communities
—While goldenrod species are often found to be allelopathic in laboratory settings, its importance in controlling plant community dynamics has been much more difficult to assess. We designed a study to determine whether allelopathy is related to the success of goldenrods in abandoned agricultural land. To accomplish this, we conducted laboratory bioassays for six co-occurring goldenrod species ...
