Changes in leaf physiology caused by Calacarus heveae (Acari, Eriophyidae) on rubber tree
(Springer, 2012-06-01)
The influence of Feres on physiological processes was evaluated in two rubber tree clones. Experiments were conducted in a greenhouse with 5-month-old potted seedlings of RRIM 600 and GT 1 clones, that were either infested ...
Increased grassland arthropod production with mammalian herbivory and eutrophication: a test of mediation pathways
(Ecological Society of America, 2017-12)
Increases in nutrient availability and alterations to mammalian herbivore communities are a hallmark of the Anthropocene, with consequences for the primary producer communities in many ecosystems. While progress has advanced ...
Predation on artificial caterpillars following understorey fires in human-modified Amazonian forests
(2022-01-01)
Tropical forests are facing several impacts from anthropogenic disturbances, climate change, and extreme climate events, with potentially severe consequences for ecological functions, such as predation on folivorous ...
Indirect suppression of photosynthesis on individual leaves by arthropod herbivory
(Oxford University Press, 2009-02)
Background: Herbivory reduces leaf area, disrupts the function of leaves, and ultimately alters yield and productivity. Herbivore damage to foliage typically is assessed in the field by measuring the amount of leaf tissue ...
Ecological consequences of primary and secondary seed dispersal on seed and seedling fate of Dipteryx oleifera (Fabaceae)
(Universidad de Costa Rica, 2010)
Soybean defense induction to Spodoptera cosmioides herbivory is dependent on plant genotype and leaf position
(2018-02-01)
Plants have evolved a diverse array of defensive mechanisms against biotic and abiotic stresses, which can be either constitutive or inducible. Variation in plant-intrinsic factors such as the genotype and the leaf position ...
Impact of volcanic ash deposition on foliar productivity and insect herbivory in northern Patagonia deciduous forests
(Asociación Argentina de Ecología, 2014)
Intermediate harvesting intensities enhance native tree performance of contrasting species while conserving herbivore diversity in a Patagonian woodland
(Elsevier Science, 2021-03)
Sustainable forest management should optimise the balance between tree productivity and biodiversity conservation. One strategy to achieve both is the use of native plantations in biomass extraction systems. However, it ...
Patterns of insect-mediated damage in a Permian Glossopteris flora from Patagonia (Argentina)
(Elsevier Science, 2018-10-15)
A total of 2523 fossil plant specimens from the La Golondrina Formation (Permian, Santa Cruz Province, Argentina) were examined in order to assess the diversity, frequency and representation of insect damage. Although no ...
Community structure of mites (Arachnida: Acari) in six rubber tree clones
(Taylor & Francis Inc, 2013-12-01)
Host plant cultivar may determine the occurrence and abundance of both herbivorous arthropods and of other species that interact with them. We analysed the acarofauna in six rubber tree clones to identify the effect of ...
