Trading direct for indirect defense? Phytochrome B inactivation in tomato attenuates direct anti-herbivore defenses whilst enhancing volatile-mediated attraction of predators
(Wiley Blackwell Publishing, Inc, 2016-12)
Under conditions of competition for light, which lead to the inactivation of the photoreceptor phytochrome B (phyB), the growth of shade-intolerant plants is promoted and the accumulation of direct anti-herbivore defenses ...
GABA(A) receptor blockade in dorsomedial and ventromedial nuclei of the hypothalamus evokes panic-like elaborated defensive behaviour followed by innate fear-induced antinociception
(ELSEVIER SCIENCE BV, 2009)
Dysfunction in the hypothalamic GABAergic system has been implicated in panic syndrome in humans. Furthermore, several studies have implicated the hypothalamus in the elaboration of pain modulation. Panic-prone states are ...
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 effects of biostimulants on induced plant defense
(Frontiers Media S.A., 2022)
Induced defenses within food webs: The role of community trade-offs, delayed responses, and defense specificity
(2009)
In nature, prey and predator species are embedded in complex networks of ecological interactions. As a
consequence, organism level reactions such as predator-induced prey defenses will not only influence
the dynamics of ...
Increment Coring Induced Traumatic Resin Ducts in White Spruce But Not in Lodgepole Pine
(Tree-Ring Society, 2020-01)
Injury from sampling increment cores may induce defense responses in trees, which may vary between species and reflect differing defense allocation strategies against attack by insects and pathogens. We recorded presence ...
Solar UVB-inducible ethylene alone induced isoflavonoids in pods of field-grown soybean, an important defense against stink bugs
(Pergamon-Elsevier Science Ltd, 2020-10)
Solar UV-B radiation enhances constitutive and inducible plant defenses against herbivore insects. Although inducible defenses in leaves damaged by lepidotperan larvae and other chewing insects are well known, almost nothing ...
X-ray computed tomography reveals that intraspecific competition promotes soldier differentiation in a one-piece nesting termite
(Blackwell Publishing Ltd, 2017)
© 2017 The Netherlands Entomological Society Investment in soldier production in eusocial lineages involves a trade-off between maintenance costs and defense benefits. Termites are eusocial insects that live in colonies ...
Adaptive prey behavior and the dynamics of intraguild predation systems
(ELSEVIER SCIENCE BV, 2010-09-06)
Intraguild predation constitutes a widespread interaction occurring across different taxa, trophic positions
and ecosystems, and its endogenous dynamical properties have been shown to affect the abundance
and persistence ...
Panic-like defensive behavior but not fear-induced antinociception is differently organized by dorsomedial and posterior hypothalamic nuclei of Rattus norvegicus (Rodentia, Muridae)
(Associação Brasileira de Divulgação Científica, 2012)
The hypothalamus is a forebrain structure critically involved in the organization of defensive responses to aversive stimuli. Gamma-aminobutyric acid (GABA)ergic dysfunction in dorsomedial and posterior hypothalamic nuclei ...
