The Evolution of Resistance and Tolerance to Herbivores
Tolerance and resistance are two different plant defense strategies against herbivores. Empirical evidence in natural populations reveals that individual plants allocate resources simultaneously toExpand

Defensive role of leaf trichomes in resistance to herbivorous insects in Datura stramonium
This study assessed the role of leaf trichome density as a component of resistance to herbivores, in six populations of Datura stramonium. Phenotypic selection on plant resistance was estimated forExpand

EVOLUTION OF MIXED STRATEGIES OF PLANT DEFENSE ALLOCATION AGAINST NATURAL ENEMIES
Abstract –In this study we present a simple optimization model for the evolution of defensive strategies (tolerance and resistance) of plants against their natural enemies. The model specificallyExpand

POPULATION VARIATION IN THE COST AND BENEFIT OF TOLERANCE AND RESISTANCE AGAINST HERBIVORY IN DATURA STRAMONIUM
In this study we examine the hypothesis that divergent natural selection produces genetic differentiation among populations in plant defensive strategies (tolerance and resistance) generatingExpand

Assessing the ecological status of Mammillaria pectinifera Weber (Cactaceae), a rare and threatened species endemic of the Tehuacán-Cuicatlán Region in Central Mexico
Abstract Mammillaria pectinifera , is a rare cactus of central Mexico currently threatened by extinction due to its restricted geographical range, high habitat specificity, relatively low growthExpand

Evolutionary ecology of Datura stramonium: equal plant fitness benefits of growth and resistance against herbivory
Abstract This study evaluated how natural selection act upon two proposed alternatives of defence (growth and resistance) against natural enemies in a common garden experiment using genetic materialExpand

Evaluación del riesgo de extinción de Mammillaria pectinifera, cactácea endémica de la región de Tehuacán-Cuicatlán
Mammillaria pectinifera (Cactaceae) is an endemic species from the Tehuacan-Cuicatlan region at the Mexican States of Puebla and Oaxaca. Although it is considered as a threatened species underExpand

Quantitative genetics of plant tolerance and resistance against natural enemies of two natural populations of Datura stramonium
Plants can respond to damage from natural enemies through resistance and/or tolerance. Evolution of these traits among natural plant populations can be constrained by (1) the absence of geneticExpand

Geographic association and temporal variation of chemical and physical defense and leaf damage in Datura stramonium
The evolution of plant defense traits has traditionally been explained trough the “coevolutionary arms race” between plants and herbivores. According to this, specialist herbivores have evolved toExpand
