Download or read book Roles of Seed Dispersal and Environmental Filters in Establishment of the Dominant Shrubs written by Benjamin Lawrence Dows and published by . This book was released on 2014 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Patterns of the expansion of woody cover into grasslands on barrier islands of the Virginia coast were investigated. Seed dispersal of the dominant shrub Morella spp., was sampled deploying seed traps (n = 82) throughout a landscape under shrub encroachment pressure on Hog Island, VA. Traps were placed underneath: fruiting Morella, non-fruiting Morella, co-occurring species (Iva frutescens and Baccharis halimifolia) and in grass land, (no shrub cover). Environmental filters that act upon dispersed seeds and subsequently determine establishment patterns were also investigated. Dispersal distribution throughout the encroachment zone was leptokurtic and dispersal among cover types suggest co-occurring shrub species facilitate dispersal by functioning as bird perches. Interaction of biotic and abiotic factors mediate a complex process of establishment by influencing dispersal, germination and seedling survival to ultimately determine distribution patterns of woody plants in coastal environments.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the nutrient-poor soils characteristic of coastal environments, symbiotic association with the nitrogen-fixing root endosymbiont Frankia is essential to establishment and survival of the woody shrub Morella cerifera. Nutrient deficiency quickly becomes severe unless seedlings are infected by Frankia soon after germination. However, the means of arrival of Frankia prior to shrub establishment has not been determined. Using sterilized lab-grown M. cerifera seedlings and fecal samples collected from passerine birds on the Eastern Shore of Virginia, viability of avian dispersal of the bacteria was tested. Although passerine fecal samples did produce nodules on some sterilized M. cerifera seedlings, these experimental inoculations did not lead to significantly higher likelihood of nodulation, relative to sterilized reference seedlings. Non-sterilized seedlings displayed greatest percent nodulation; results suggest that passerines contribute to Frankia dispersal, but also that the actinomycete is contained on or within viable seeds or fruits of M. cerifera, and therefore may be co-dispersed directly from the parent plant.

Download or read book Seed Dispersal written by David R. Murray and published by Academic Press. This book was released on 2012-12-02 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed Dispersal focuses on the mechanics and processes involved in seed dispersal, including its implications in ecology, animal behavior, plant and animal biogeography, speciation, and evolution. The selection first elaborates on the aerial motion of seeds, fruits, spores, and pollen and seed dispersal by water. Discussions focus on seed dispersal by rain, river, and flood, effective seed dispersal by ocean currents compared to other vectors, aerodynamic forces and their effects, and launching and release mechanisms. The text then takes a look at seed dispersal syndromes in Australian Acacia, including inference of dispersal syndromes, seed dispersal syndromes, ecological consequences of seed dispersal, and evolutionary derivation of dispersal syndromes. The publication ponders on seed dispersal by fruit-eating birds and mammals, rodents as seed consumers and dispersers, and seed dispersal in relation to fire. Topics include fire as a dispersal vector, long distance dispersal, granivorous rodents and the fates of seeds, determinants of the fate path, population ecology of seed dispersal, and foraging for fruits. The selection is a valuable reference for researchers interested in the factors involved in seed dispersal.

Book excerpt: Frugivorous birds provide dispersal for a large portion of plant species, yet little research has explored how plant-frugivore mutualisms influence plant community diversity. Recent work in tropical forests demonstrates that many fruiting plant species which are rare in a particular time and place occupy a disproportionately high fraction of the diet of avian frugivores. This rare-biased or anti-apostatic pattern of frugivory is a previously unexplored mechanism promoting the maintenance of diverse plant communities. The present work entails the first attempt to determine experimentally if anti-apostatic frugivory is a general pattern among common frugivorous birds in multiple environments. Between September 2016 and October 2017, I performed field experiments in Argentina, Puerto Rico, and Pennsylvania in which I presented arrays of artificial fruit in contrast to a background of abundant real fruit. I varied the color and density of artificial fruit arrays and measured the interest of visiting birds with camera traps. I found that wild birds exhibited anti-apostatic selection in most, but not all circumstances. In four of five experiments, avian visitors were more interested in artificial fruit which appeared novel than those which resembled a common fruit in that environment. Avian visitors also made more visits-per-fruit in low-density arrays (10 fruit), compared to high-density arrays (100 fruit). This is the first experimental evidence for anti-apostatic frugivory, demonstrating that frugivorous birds may equalize seed dispersal in plant communities where abundances are imbalanced.
