The aim of this paper is to review knowledge of the ecophysiological mechanisms influencing the dynamics of plant populations in grazed swards. Such an objective requires some definitions. Firstly, it is necessary to define “ecophysiology” as the study of the interactions between biological individuals (plants) with their own environment: how individuals perceive and react to any constraint and change of their environment, and how the functioning of plants as a population can modify their own…

Ecophysiology of C4 Forage Grasses—Understanding Plant Growth for Optimising Their Use and Management
TLDR
A critical appraisal is given of the need for revision and change of paradigms as a means of improving and consolidating the knowledge on animal production from pastures, which idealizes efficient, sound and sustainable grazing management practices necessary to realize the existing potential for animal production in the tropics.
Ecofisiologia de plantas forrageiras
The study was conducted in order to conduct a review of the importance of ecophysiology of forage plants, to address the impacts of biotic and abiotic factors on plants and their morphological and
Botanical Survey of Floral Species and Animal Feeding Values in Pasturelands of Environments with a Mediterranean Climate
The native flora of Mediterranean environments with meso-Mediterranean zones, instead of being protected by European Union and Italian government law, continue to be threatened as a result of the
How the Intercropping between Corn and Palisade Grass Cultivars Affects Forage Production and Pastures Characteristics under Grazing
TLDR
The corn and forage intercropping did not affect the growth and development of palisade grass pastures and it is a viable alternative for the crop-livestock integrated system.
Animal production and soil characteristics from integrated crop-livestock systems: toward sustainable intensification.
TLDR
Focusing on grazing animals as drivers of agroecosystem change, the benefits of grazed cover crops in rotation with cash crops for primary and secondary production and for soil physical, chemical, and biological parameters are highlighted.
Physiological and production responses of four grasses from the genera Urochloa and Megathyrsus to shade from Meliaazedarach L.
TLDR
Oaxaca and Yacaré appear to be more adapted to shade by responding with greater production stability and better forage nutritive quality, although nutritional quality was better during the windy season.
Grazing pressure on forage availability of Brachiaria decumbens
The objective of this research was to evaluate the effect of two grazing pressures on the availability of Brachiaria Decumbens forage. The research was carried out at the Quilichao Experimental
Morfogênese e fluxo de tecidos em capim Tanzânia sob diferentes ofertas de forragem
TLDR
The use of forage allowance of 11% of body weight for tanzania grass managed under continuous grazing and variable stocking rate, seems to be more sustainable.
Contribution of tiller age category to herbage accumulation of Marandu palisadegrass under two fertilization regimes
Based on the hypothesis that climate and fertilizers influence the proportion of tiller age categories in the canopy and, consequently, in herbage accumulation, the objective of this study was to

ANALYSIS OF THE COEXISTENCE MECHANISMS FOR GRASSES AND LEGUMES IN GRAZING SYSTEMS
TLDR
A model that extends a recently proposed pasture model by including selective grazing and spatial considerations is developed, which has important implications for attempts to control the legume content of mixed species communities.
Effect of nitrogen on some morphogenetic traits of temperate and tropical perennial forage grasses.
TLDR
The effect of nitrogen on the morphogenesis of for-age grasses of temperate and tropical climates is analyzed, focusing on the nitrogen factor, which takes into account its role in the expression of plant growth.
Reserve formation and recycling of carbon and nitrogen during regrowth of defoliated plants.
TLDR
In order to understand competitive interactions between defoliated plants there is a need for field experiments that quantify storage and remobilization of both carbon and nitrogen and a range of techniques that might allow such field experimentation in the future are discussed.
A Spatially Explicit Population Model of Stoloniferous N-Fixing Legumes in Mixed Pasture with Grass
TLDR
It is argued that legume dynamics in mixed pastures cannot be fully understood without combining ecological and physiological concepts of species interactions at three different scales: competitive interactions at the patch-scale, dispersal at the between-patch scale, and seasonality at the field-scale.
Interspecific competition in natural plant communities: mechanisms, trade-offs and plant-soil feedbacks
TLDR
It is argued that selection in nutrient-poor habitats is not necessarily on a high competitive ability for nutrients and a high growth rate, but rather on traits which reduce nutrient losses (low tissue nutrient concentrations, slow tissue turnover rates, high nutrient resorption efficiency).
A comparative approach to examine competitive response of 48 wetland plant species
TLDR
A different approach is suggested towards the study of competitive response, with a conceptual model including three different response types: (1) escape; (2) foraging; and (3) persistence.
Soil P resources, plant growth and rooting characteristics in nutrient poor upland grasslands
A field study was undertaken to establish the demand for P by mixed herbage, manipulated by cutting regimes, and the extent to which orthophosphate alone in soil solution could meet this demand from
Complex dynamics in a carbon-nitrogen model of a grass-legume pasture.
On the opportunity cost of the photosynthate invested in stem elongation reactions mediated by phytochrome
TLDR
Testing the growth of both isolated individuals and canopies of the weed Amaranthus quitensis shows that stem elongation, stem growth, and total plant biomass can be increased by reducing the flux of R light received by the stems without affecting the light climate of the leaves.
