(Birkhauser Verlag Basel, 1998)We characterized the induction of hydroxamic acids (Hx) by aphid infestation in the wild wheat Triticum uniaristatum by addressing the following questions: i) Do different leaves have similar responses to aphid damage?, ...
-
(Springer New York LLC, 1997)Hydroxamic acids (Hx) are natural products of Gramineae that are associated with cereal resistance to pests. We aimed at characterizing the induction of Hx accumulation in seedlings of wheat. Triticum aestivum, by short-term ...
-
(American Ornithologist Society, 1999)We studied the activity of three intestinal membrane-bound digestive enzymes in the Rufous-tailed Plantcutter (Phytotoma rara), one of the smallest species of avian herbivores. We selected the disaccharidases (sucrase and ...
-
(Springer Verlag, 1996)The effects of temperature and photoperiod on the ability of wheat (Triticum aestivum L.) seedlings to show induced responses (increased accumulation of hydroxamic acids, Hx) upon infestation by the bird cheery-oat aphid. ...
-
(2011)Floral damage can reduce flower attractiveness for pollinator service. However, the reproductive impact of flower herbivory may be contingent on a petal that is damaged. Flowers having nectar guides are expected to suffer ...
-
(2009)Pollination is a requisite for sexual reproduction in plants and its success may determine the reproductive output of individuals. Pollinator preference for some floral designs or displays that are lacking or poorly developed ...
-
(2009)Folivory is lower in forest fragments of the Maulino forest than in continuous stands. We experimentally assessed whether depressed folivory is related to a reduction in foliar palatability caused by the more xeric ...
-
(2013)Increasing evidence suggests that, depending on the structural complexity of a plantation, it can act as complementary habitat for insectivore birds and mammals. The magnitude of interactions such as insectivory, in turn, ...
-
(Royal Botanical Society of Belgium, 2016)Background and aims - Once introduced into new regions, exotic species often experience shifts in resource allocation in response to the different environmental conditions found in the introduction range. Plants naturally ...
-
(2011)Background - Habitat fragmentation may have detrimental effects on both plant-mutualistic (i.e. pollination) and plant-antagonistic interactions (i.e. foliar herbivory). Such double negative effects may lead to a change ...
-
(2000)Nothofagus species from Chile and New Zealand were surveyed in the field for invertebrate abundance and leaf feeding damage and in the laboratory for antifeedant activity against leafrollers (Ctenopsteustis obliquana, ...
-
(2012)Theoretical models predict nurse plant facilitation enhances species richness by ameliorating stressful environmental conditions and expanding distributional ranges of stress-intolerant species into harsh environments. ...
-
(2001)Beilschmiedia miersii is an endemic endangered tree of central Chile, protected only in La Campana National park. The regeneration of B. miersii is very low, presumably due to strong fruit and seedling predation by livestock. ...
