Why do plant species need to promote cross-fertilization rather than self-fertilisation?
Self- and Cross-Fertilization in Plants. I. Functional Dimensions, by David G. Lloyd and Daniel J. Schoen © 1992 The University of Chicago Press.AbstractMany functional-ecological, morphological, and physiological-factors affect the occurrence of selffertilization. Six modes of self-pollination are distinguished. These differ in whether they utilize specialized flowers, whether they involve the transfer of pollen within or between flowers, whether they are autonomous or mediated by vectors, and their timing relative to opportunities for outcrossing. The various modes of selfing are subject to different structural constraints. Prepotency, the preferential success of cross-pollen in achieving fertilizations when it competes with self-pollen, influences the frequency of selffertilization in some species. The amount of self-fertilization may depend on environmental conditions and the vector species visiting each flower and may vary among the flowers of one plant. To gain information on the prevalence of autonomous self-pollination, 66 species for which the degrees of selfcompatibility and autofertility (seed set in isolation) have been published were surveyed. Partially selfincompatible species (in which the seed set is lower after self-pollination than after separate outcrosses) have on average lower autofertility than self-compatible species (in which self- and cross-pollinations succeed equally well), but some partially self-incompatible species have considerable autofertility and some self-compatible species have none. A number of features of floral morphology and phenology are associated with high Autofertility Indices.
What do national parks promote?
They promote a safe environment where you can have fun and let loose and enjoy some activities in a natural environment. The parks promote conservation of our native species of plants and animals.
The creation of wildlife refuges and the enforcement of game laws are conservation measures that promote increased?
Preservation of species
Trypsin inhibitors in tomato potato and alfalfa plants are best described as factors that?
promote species survival
How does the creations of variations in species promote survival?
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
What are species that play a critical role in maintaining the structure of an ecological community?
Keystone species are crucial in maintaining the structure of an ecological community. These species have a disproportionately large impact on their environment relative to their abundance. They help regulate the populations of other species, promote biodiversity, and contribute to the overall functioning of the ecosystem.
What is a threatened species of shark?
The scalloped hammerhead shark is considered a threatened species due to overfishing, bycatch, and habitat destruction. Conservation efforts are underway to protect this species and promote their recovery in the wild.
How can you reduce the problem of too many people on your planet?
Let God worry about it or the Secular answer: Get another planet or don't promote your species.
Why do plant species need to promote cross-fertilisation rather than self-fertilisation?
Pls replied the question to the answer back and I need the answer by tomorrow.
The particular species that come and go in the process of succession depend on the what?
The particular species that come and go in the process of succession depend on the available resources, environmental conditions, and interactions between species. As the environment changes over time, different species are able to establish and thrive. Each species alters the habitat in ways that either promote or inhibit the growth of other species, leading to a dynamic process of community change.
Resource partitioning would be most likely to occur between?
Competing species that share similar ecological niches and resources. By partitioning resources, such as food, space, or time, these species can coexist by reducing direct competition and allowing each species to specialize in utilizing different resources. This can help to minimize competition and promote species diversity within a community.
