Light Regulation of Plant Defense
(Annual Reviews, 2014-04)
Precise allocation of limited resources between growth and defense is critical for plant survival. In shade-intolerant species, perception of competition signals by informational photoreceptors activates shade-avoidance ...
Scopolamine in Brugmansia suaveolens (Solanaceae): Defense, allocation, costs, and induced response
(SpringerDordrechtHolanda, 2007)
SOLENOPSIS (HYMENOPTERA, FORMICIDAE) FIRE ANT REACTIONS TO ATTACKS OF PSEUDACTERON FLIES (DIPTERA, PHORIDAE) IN SOUTHEASTERN BRAZIL
(Amer Entomol Soc, 1995-07-01)
We studied the responses of Solenopsis fire ants to Pseudacteon phorid fly attacks in southeastern Brazil. The presence of these phorid parasites triggered a suite of phorid-specific defense responses including reduced ...

Defensive responses to threat scenarios in Brazilians reproduce the pattern of Hawaiian Americans and non-human mammals
(Associação Brasileira de Divulgação Científica, 2008)
A former study with scenarios conducted in Hawaii has suggested that humans share with non-human mammals the same basic defensive strategies - risk assessment, freezing, defensive threat, defensive attack, and flight. The ...
Activation of early defense signals in seedlings of nicotiana benthamiana treated with chitin nanoparticles
(MDPI, 2020)
Chitin is an excellent material for the synthesis of nanoparticles because it is an elicitor and can form nanostructured materials. The application of chitin nanoparticles (CNPs) in plants can activate early defense responses ...
Effects of intra-PAG infusion of ovine CRF on defensive behaviors in Swiss-Webster mice
(Elsevier B.V., 2007-01-25)
The midbrain dorsal periaqueductal gray (DPAG) is part of the brain defensive system involved in active defense reactions to threatening stimuli. Corticotrophin releasing factor (CRF) is a peptidergic neurotransmitter that ...

The defensive behavioral patterns of captive white-lipped and collared peccary (Mammalia, Tayassuidae): an approach for conservation of the species
(Springer, 2017-06-01)
Defensive behavioral patterns in response to human-induced rapid environmental change can affect animals' fitness and may play a role in species conservation status. To test this hypothesis, we compared the risk assessment ...
