Dietary specialization influences the efficacy of larval tortoise beetle shield defenses
(SpringerNew YorkEUA, 2005)
Resource defense polygyny shifts to female defense polygyny over the course of the reproductive season of a Neotropical harvestman
(SPRINGER, 2008)
Although studies classify the polygynous mating system of a given species into female defense polygyny (FDP) or resource defense polygyny (RDP), the boundary between these two categories is often slight. Males of some ...
Testing the optimal defense hypothesis in Stryphnodendron adstringens (Fabaceae, Mimosoideae) leaves: the role of structure, number, position and nectar composition of extrafloral nectaries
(2017-10-01)
Stryphnodendron adstringens is a common Cerrado tree that possesses extrafloral nectaries (EFNs) on its leaves, which are located at the base and apex of the rachis and along the secondary veins. The position of EFNs and ...
The role of plant 90-kDa heat shock proteins in plant immunity
(Springer Nature Switzerland AG, 2016)
Heatshock proteins of 90 kDa (Hsp90) are present in most of the living organisms. Their main function is to preserve cell viability by participating in the assembly, stabilization, maturation and activation of key signaling ...
Differences in effects of pyrrolizidine alkaloids on five generalist insect herbivore species
(2005)
The evolution of the diversity in plant secondary compounds is often thought to be driven by insect herbivores, although there is little empirical evidence for this assumption. To investigate whether generalist insect ...
Induced resistance against leafminer eggs by extrusion in young potato plants
(Taylor & Francis Ltd, 2007-07)
Egg extrusion patterns were investigated as an inducible defensive mechanism in potato plants against the leafminer Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae). Increased multiplication rates in leaf cells ...
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 ...
