Assessment of correlational selection on tolerance and resistance traits in a host plant-parasitic plant interaction
(Springer, 2001)
Resistance and tolerance are considered to be different plant strategies against disease. While resistance traits prevent hosts becoming parasitized or reduce the extent of parasitism, tolerance traits reduce the fitness-impact ...
Ameliorative effects of nurse shrubs on soil chemical characteristics are driven by plant size in the Monte desert
(Taylor & Francis, 2017-08)
In deserts, shrubs determine landscape structure and influence plant productivity by creating nutrient-enriched environments. Attributes vary among shrub species, thus their contribution to soil characteristics is expected ...

Factors affecting pollinator movement and plant fitness in a specialized pollination system
(2011)
The rate of pollen exchange within and among flowers may depend on pollinator attraction traits such as floral display size and flowering plant density. Variations in these traits may influence pollinator movements, pollen ...
How does spatial micro-environmental heterogeneity influence seedling recruitment in ironstone outcrops?
(Wiley-Blackwell, 2021-03-01)
Questions Environmental filters limit the set of potentially coexisting species in plant communities. Paradoxically, some of the world's most biodiverse communities are subjected to strong abiotic filters. We explored how ...
Experimental and modelling approach to the legume-Rhizobium interaction: test of plant-host sanctions in co-inoculated plants with fixing and non-fixing strains
(2013)
We tested the plant host sanction hypothesis using soybean plants co-inoculated with two rhizobial strains, a normally N2 fixing strain and a mutant derivative that lacks nitrogenase activity but has the same nodulation ...
Interception loss, throughfall and stemflow by Larrea divaricata: The role of rainfall characteristics and plant morphological attributes
(Wiley, 2019-08-28)
Rainfall partitioning into interception loss, throughfall and stemflow affects the amount and the spatial heterogeneity of water entering into the soil at the patch scale, strongly controlling net primary productivity of ...
Análise molecular e fenotípica de eventos elite de Citrus sinensis geneticamente modificado em condições de campo
(Universidade Federal de São CarlosUFSCarCâmpus ArarasEngenharia Agronômica - EAg-Ar, 2022-09-27)
Brazil stands out worldwide as the largest orange producer. The sector has faced challenges related to phytosanitary problems and among these problems are bacterial diseases, such as citrus variegated chlorosis (CVC), ...
Variation in sexual expression in relation to plant height and local density in the andromonoecious shrub Caesalpinia gilliesii (Fabaceae)
(Springer, 2010-05)
Based on the hypothesis that both plant size and local conspecific density influence allocation to female/male functions, we explored the relationship between plant height, local conspecific density, sexual expression, and ...
