Chemical defense in harvestmen (Arachnida, Opiliones): Do benzoquinone secretions deter invertebrate and vertebrate predators?
(Springer, 2005-11)
Two alkylated 1,4-benzoquinones were identified from the defensive secretion produced by the neotropical harvestman Goniosoma longipes (Gonyleptidae). They were characterized as 2,3-dimethyl-1,4-benzoquinone and ...

Indirect measures of reproductive effort in a resource-defense polygynous ungulate: Territorial defense by male guanacos
(Springer Tokyo, 2012-01)
Trade-offs between reproductive effort and activities that are likely to enhance survival have been studied extensively in harem defense ungulates. However, among resource defense systems, ecological determinants of the ...
Stereotyped defensive behaviours in frogs of the genus Odontophrynus (Amphibia: Anura: Odontophrynidae)
(Herpetological Society of Japan, 2018-08)
Observations on stereotyped defensive behaviours are presented for 7 frog species of the Neotropical genus Odontophrynus from Argentina and Uruguay. Seven stereotyped postures were observed, among which the most common ...
Plant invasion alters latitudinal pattern of plant-defense syndromes
(Ecological Society of America, 2021-12)
The relationship between herbivory and latitude may differ between native and introduced populations of invasive plants, which can generate latitudinal heterogeneity in the strength of enemy release. However, still little ...
Coevolutionary arms race between a specialist brood parasite, the Screaming Cowbird, and its host, the Grayish Baywing
(Springer, 2019-10)
Interspecific brood parasites exploit the parental care of host species. This exploitation entails fitness costs for the hosts, which favor the evolution of antiparasitic defenses. Host defenses select for counter-defenses ...
Non-digestible proteins and protease inhibitors: Implications for defense of the colored eggs of the freshwater apple snail pomacea canaliculata
(National Research Council Canada-NRC Research Press, 2019-02-01)
Apple snails (Pomacea Perry, 1810) are successful invaders that cause ecological perturbations, economic losses, and medical issues. A peculiar trait of this snail is a high biological potential, related to the absence of ...
Transcriptome profiling of Fusarium solani f. sp. eumartii -infected potato tubers provides evidence of an inducible defense response
(Academic Press Ltd - Elsevier Science Ltd, 2010-12)
Fusarium solani f. sp. eumartii is a phytopahtogenic fungus that causes dry rot in potato tubers. To analyze andcharacterize the transcriptomic profile of Solanum tuberosum cv. Spunta against F. solani f. sp. eumartiiinfection, ...
Intentional and unintentional selection during plant domestication: herbivore damage, plant defensive traits and nutritional quality of fruit and seed crops
(Wiley Blackwell Publishing, Inc, 2021-05)
Greater susceptibility to herbivory can arise as an effect of crop domestication. One proposed explanation is that defenses decreased intentionally or unintentionally during the domestication process, but evidence for this ...
Resource-defense polygyny and self-limitation of population density in free-ranging guanacos
(Oxford Univ Press Inc, 2016-01)
Although ecologists and managers have been increasingly preoccupied with the crowding consequences of overabundant herbivores,the potential role of territorial behavior as a self-regulatory agent has seldom been considered. ...
