Competition in a natural system may be interspecific or intraspecific. In semiarid ecosystems, competition for resources between established neighboring grass species and newly recruited seedlings is very high. To examine the effects of grass species density, growing space and time of establishment on Eucalyptus victrix seedlings (interspecific competition), and the effect of density and growing space within E. victrix (intraspecific competition) we conducted an experiment under controlled… Expand

Figures and Tables from this paper

Interspecific Competition Between Coleogyne ramosissima Seedlings and Bromus rubens
TLDR
Results of this study revealed that some Coleogyne mortalities occurred in the absence of interspecific competition, and that growth among surviving seedlings were significantly reduced under conditions of increased density of neighboring Bromus and early Bromus establishment. Expand
Seasonality and facilitation drive tree establishment in a semi-arid floodplain savanna
TLDR
It is demonstrated that interactions between tree seedlings and perennial grasses vary seasonally, and timing of tree germination may determine the importance of facilitation or competition in structuring savanna vegetation because of fluctuations in abiotic stress. Expand
Interactive Effects of Simulated Herbivory and Interspecific Competition on Survival of Blackbrush (Coleogyne ramosissima) Seedlings
TLDR
Results of this study suggest that simulated rodent herbivory and B. rubens competition limited survival independently, and that a combination of herbvory and competition caused synergistic reductions in C. ramosissima seedling survival. Expand
Weeds in Eucalyptus globulus subsp. maidenii (F. Muell) establishment: effects of competition on sapling growth and survivorship
TLDR
Early negative effects of competition on growth were evident as from the second month after establishment, and both seedlings and 1- year-old saplings were more affected than 2- and 3-year-old ones. Expand
Intraspecific Competition Among Blackbrush (Coleogyne ramosissima) Seedlings in a Controlled Environmental Glasshouse
TLDR
Results of this common garden study revealed that mortality of blackbrush seedlings occurred in the absence of intraspecific competition, and that growth characteristics were significantly reduced with increasing neighbor density and decreasing available growing space among surviving seedlings. Expand
Interference of seeding and regrowth of signalgrass weed (Urochloa decumbens) during the initial development of Eucalyptus urograndis (E. grandis × E. urophylla)
TLDR
Evaluating the effects of different densities and distances of Urochloa decumbens seeded and regrowth during the early growth of Eucalyptus urograndis demonstrates that U. decumben adversely affected the growth of eucalyPTus, without statistical differences between distances, and weeds in regrowth affecting Eucallyptus growth more than seeded weeds. Expand
Interference of Urochloa decumbens and Panicum maximum in the initial growth of six clones of Eucalyptus urograndis
TLDR
Both weeds were affected by eucalyptus, but Guinea grass was more sensitive than signal grass. Expand
Does polyembryony reduce seed germination and seedling development in Eriotheca pubescens (Malvaceae: Bombacoideae)?
TLDR
Polyembryony and apomixis affected germination and led to smaller seedlings compared with monoembryonic sexual counterparts, which may have ecological consequences within the Cerrado, where seedling establishment is critical for species persistency and distribution. Expand
Selective herbicides for establishment of Eucalyptus benthamii plantations
TLDR
Results confirm one early report of flumioxazin effectiveness and identify imazamox and imazapic as new selective herbicides for eucalyptus culture. Expand
Effect of increasing densities of Urochloa brizantha cv. Marandu on Eucalyptus urograndis initial development in silvopastoral system
TLDR
Evaluating the effect of increasing densities of Urochloa brizantha cv. Expand

Grass interference limits resource availability and reduces growth of juvenile red pine in the field
TLDR
Seedling growth reductions induced by grass competition were associated with multiple environmental stressors in the field and not restricted to water stress as was observed in earlier studies with pine species at low and mid-latitude sites. Expand
Competition for soil water between annual plants and blue oak (Quercus douglasii) seedlings
TLDR
It is suggested that competition for soil water with introduced annual species contributes to the increased rate of blue oak seedling mortality currently observed in California woodland systems. Expand
Growth and Survival of Prosopis glandulosa Seedlings Associated with Shade and Herbaceous Competition
Both shade and herbaceous competition reduced the germination and growth of Prosopis glandulosa Torr. (honey mesquite). Natural and artificial shade was used and herbaceous competition wasExpand
The Role of Competition in Plant Communities in Arid and Semiarid Regions
TLDR
This paper reviews the available evidence for competition in plant communities in arid and semiarid regions and demonstrates that competition certainly occurs in these communities and involves many different species; in several instances it appears to be important in the determination of community structure. Expand
Mortality of lignotuberous seedlings of Eucalyptus species after an intense fire in montane forest
TLDR
It was shown that an individual was more likely to survive if it was large and growing vigorously before the fire, and enhanced if the individual was growing in a patch of low litter load and if it experienced a locally low fire intensity. Expand
TREE-GRASS INTERACTIONS IN SAVANNAS 1
Savannas occur where trees and grasses interact to create a biome that is neither grassland nor forest. Woody and gramineous plants interact by many mechanisms, some negative (competition) and someExpand
Application of the ecosystem mimic concept to the species-rich Banksia woodlands of Western Australia
TLDR
The structure and functioning of a natural Banksia woodland at Moora, Western Australia is described and information on seasonal water use and nutrient cycling in the dominant tree species Banksia prionotes is used to highlight the pivotal role of deep rooted summer growing trees in the maintenance of sustainability of the system.

Growth ofProsopis caldeniaseedlings in the field as related to grazing history of the site and in a greenhouse as related to different levels of competition fromStipa tenuis
TLDR
Both overgrazing and high levels of grass competition may limit the establishment of P. caldenia seedlings in grasslands, particularly under conditions of water shortage. Expand
Studies on the Status of Unburnt Eucalyptus Woodland at Ocean Grove, Victoria. II* The Differential Seedling Establishment of Eucalyptus ovata Labill. and Casuarina littoralis Salisb.
At Ocean Grove, Vic., Eucalyptus woodland which has remained unburnt for many years is being replaced by Casuarina scrub. Neither poor germination or poor seed supply is responsible for the lack ofExpand
Herbage response to tree thinning in a Eucalyptus crebra woodland
TLDR
Recruitment of grass and forb plants, as reflected by changes in density, varied according to treatment, whilst forb recruitment was influenced mainly by tree density. Expand
