  • A new study in the Journal of Ecology reveals a number of plants that were not previously known to be part of the diet of waterbirds. (sciencenewsdaily.org)
  • One of the great challenges in ecology is to explain how large numbers of plant species are able to coexist in natural communities. (unibas.ch)
  • The results of my thesis emphasise the importance of both dispersal and competition as spatial mechanisms promoting plant coexistence and point towards novel aspects of AMF in spatial plant ecology. (unibas.ch)
  • We attempt to develop an integrative ecology, aiming at interdisciplinary problems that cover fields such as plant-animal interactions, demogenetics, complex networks of interaction, trophic webs, population genetics, spatially explicit models of gene flow mediated by animals, and the restoration of Mediterranean-type vegetation.

  • traits
  • The final project of this dissertation involved surveying the plant communities, functional traits, and ecosystem properties of 20 islands in Clarks Hill Lake reservoir, Georgia. (syr.edu)
  • 1) Traits of plants can be plastic (phenotypic plasticity) enabling individual plants to adapt to changing environmental conditions within their life span. (pik-potsdam.de)
  • 2) The variety plant organisms with different functional traits (functional diversity) enables the system to change its composition. (pik-potsdam.de)
  • However, it is largely unclear whether morphological or physiological traits are a prerequisite for plants to become epiphytes or if character (trans) formations are a result of life form shifts and lead to diversification. (frontiersin.org)
  • Evolution of fruit traits in Ficus subgenus Sycomorus (Moraceae): to what extent do frugivores determine seed dispersal mode? (figweb.org)
  • However, dispersal may also evolve in response togeographic variation in other life-history traits, especially the mating system. (islandscholar.ca)
  • Here,increased dispersal at range margins was tested for with a range-wide analysis ofseed dispersal and mating system traits in Abronia umbellata, a plant endemic toPacific coastal dunes of North America. (islandscholar.ca)
  • spore
  • However, previous studies have focused only on wet splash droplets formed by raindrop impact, which our results suggest are only a minor contributor to spore dispersal. (pnas.org)

  • The diaspores of endozoochorous plants are eaten by animals and humans and the hard seeds or fruit stones pass through the intestinal canal without damage (Smallwood, 1984). (springer.com)
  • 2000
  • Polyploidy has occurred extensively in angiosperms ( Leitch and Bennett, 1997 ) and is recognized as a key factor in the evolution of plants and their genomes ( Wendel, 2000 ). (plantcell.org)
  • spatial
  • First, I tested the role of spatial isolation and associated dispersal limitation on functional variation in the plant communities on 30 uninhabited islands in the Gulf of Maine. (syr.edu)
  • Glacier foreland is considered as one of the most ideal places for examining ecological succession because it presents a temporal sequence of plants at a small spatial scale over a long period. (hindawi.com)
  • The role of spatial structure for maintaining plant coexistence has so far mainly been explored by theory. (unibas.ch)
  • Competitive interactions between plants occur over relatively small spatial scales. (unibas.ch)
  • Increasing evidence for host-specificity and the fact that AMF can connect the roots of many plant species suggest that they might be involved in the spatial scales of competiton. (unibas.ch)
  • Increasing dispersal distance lead to more vegetative individuals, and decreasing dispersal distance resulted in a more aggregated spatial distribution. (unibas.ch)
  • distances
  • Previous studies have shown that plant pathogens such as rusts can be transported kilometer distances in the atmosphere ( 9 ) and even cross continents ( 10 ⇓ ⇓ - 13 ). (pnas.org)
  • New information is needed on the liberation mechanism of spores from infected plants, and how these spores might be transported over long distances. (pnas.org)
  • In addition I have developed molecular tools to track and measure seed dispersal distances by frugivorous animals. (mendeley.com)
  • propagules
  • Raindrop impact on infected plants can disperse micron-sized propagules of plant pathogens (e.g., spores of fungi). (pnas.org)
  • The classic model, the logistic, often fits the course of an epidemic of plant disease although the assumptions of propagules proportional to infected plants and random distribution of the propagules are violated. (royalsocietypublishing.org)
  • insects

  • Nevertheless, studies investigating the dispersal of small insects in natural conditions remain scarce mainly because of the difficulty of tracking the movements of these organisms. (archives-ouvertes.fr)
  • Nevertheless
  • Nevertheless, when evaluating landscape-scale dispersal, it is important to consider potential time lags in the response of species and genetic patterns to habitat fragmentation as well as to restoration. (wordpress.com)
  • functional
  • The goal of this dissertation is to test whether plant dispersal can drive ecosystem function by studying how dispersal limitation drives functional trait variation and community succession across three different study systems. (syr.edu)
  • Dispersal limitation was a key driver of functional variation in this system, with most variation attributed to species pool effects. (syr.edu)
  • I also found some support for the immigrant selection hypothesis for one trait (specific leaf area), suggesting that dispersal filters can directly select for shifts in functional composition. (syr.edu)
  • The second scope of this project was to evaluate the role of dispersal limitation as a driver of community functional trait variation and subsequent ecosystem function. (syr.edu)
  • Interestingly, plant species differed substantially in their susceptibility to different functional differences between these isolates, and this seemed to be positively linked to the percentage root colonisation. (unibas.ch)
  • In DGVMs for each biome a small amount of so called plant functional types (PFTs) is used as representatives of all different plant types existing within this biome. (pik-potsdam.de)
  • ecological
  • Glacier forelands are ideal places for investigating plant succession because there are representative ecological succession records at long temporal scales. (hindawi.com)
  • Understanding
  • Understanding the spread of spores of plant pathogens, some of which may serve as potential human allergens, is of great importance to plant and animal health. (pnas.org)
  • To gain an in-depth understanding, Dr. Céline Born traveled to Marion Island in the sub-Antarctic Indian Ocean to study Azorella selago, a "keystone" plant species due to its critical importance to ecosystem function. (axa-research.org)

  • ecosystem function
  • Ecosystem properties such as soil organic matter quality and potential nitrogen mineralization similarly varied with island isolation, suggesting that dispersal limitation can have long-term legacy effects on ecosystem function. (syr.edu)
