  • origins of herbivory
  • We suggest that the recurrent and paradoxical evolution of herbivory in liolaemids is explained by a combination of environmental conditions (promoting independent origins of herbivory in isolated cool-climate regions), ecophysiological constraints (requiring small body size in cool climates, yet high body temperatures for herbivores), and phylogenetic history. (pnas.org)
  • Relatively little is known of the earliest origins of herbivory, and it is here that fossils are most useful in revealing both the taxa present and the morphological and inferred functional abilities of fishes at this time. (royalsocietypublishing.org)
  • leaf
  • Offspring ramets were then exposed to herbivory by three different herbivore species: (1) P. minor , (2) the specialist leaf-beetle Agasicles hygrophila , and (3) the stenophagous tortoise-beetle Cassida piperata . (springer.com)
  • 5. These results, together with previous studies, demonstrate that the impact of leaf herbivory on seed production in P. arieianum depends on the timing of that herbivory relative to the accumulation and use of non-structural carbohydrates. (wiley.com)
  • Plots (15 × 15 trees) of Anacardium excelsum (Anacardiaceae) , Dalbergia retusa (Fabaceae) , Pachira quinata (Malvaceae) , Tabebuia rosea (Bignoniaceae) , and Terminalia amazonia (Combretaceae) were tested for herbivory using leaf counts and digital image analysis. (springer.com)
  • Leaf toughness was negatively correlated with SLA and foliar N. Linear regressions showed that herbivory was positively correlated with foliar N for young leaves and negatively correlated with foliar N for mature leaves. (springer.com)

  • The main objective of this study was to investigate whether green leaf herbivory, having one of the most hazardous biotic impacts, would have any direct effect on the production and emission of floral volatiles because volatiles are known to play a crucial role in pollination. (plantphysiol.org)
  • One of the most deleterious biotic influences on plants is green leaf herbivory. (plantphysiol.org)
  • The most severe consequence of green leaf herbivory is the loss of photosynthetic capacity. (plantphysiol.org)
  • However, little attention has been paid so far to the influence of green leaf herbivory on floral VOC production and emission. (plantphysiol.org)
  • The main objective of this study was to investigate whether green leaf herbivory treatment of Nicotiana suaveolens would interfere with its floral VOC production and emission. (plantphysiol.org)

  • These traits may be associated with physiological constraints imposed by herbivory. (pnas.org)

  • lineages
  • A very striking pattern emerged: herbivory has arisen multiple times in the ants, and at least five of these unrelated herbivorous lineages associate symbiotically with Rhizobiales bacteria. (phys.org)
  • Subsequently, herbivory evolved in numerous lineages of terrestrial vertebrates, and the acquisition of this mode of feeding was frequently associated with considerable evolutionary diversification in those lineages. (nhbs.com)

  • tolerance
  • Herbivory decreased above- and below-ground plant biomass by approximately 50% with a concomitant 134% increase in root N concentration but no changes in concentrations of soluble sugars, starch or non-structural carbohydrates related to herbivory tolerance. (springer.com)

  • environmental
  • The winter range aspen stands of RMNP appear to be highly resilient despite very intense herbivory by elk and harsh environmental conditions. (usu.edu)
  • Trees
  • One year after removal of the exclosure, trees browsed by elk were more likely to die as a result of herbivory than trees that were not browsed. (usu.edu)
  • biomass
  • A detailed process model of herbivory was developed, which allows both quantitative (i.e. biomass) and qualitative (i.e. taxonomic and chemical composition) components to be assessed. (oregonstate.edu)
  • willow
  • We then established 16 and 15 plots (1 m × 2.7 m) in patches of willow on the Green and Yampa Rivers, respectively, to determine whether rates of beaver herbivory of willow differed between rivers (Green versus Yampa River), seasons (fall-winter versus spring-summer), and years (spring 1998-spring 1999 versus spring 1999-spring 2000). (usgs.gov)
  • We attribute the between-river difference in herbivory to higher availability of willow, greater beaver density, and lower availability of young Fremont cottonwood ( Populus deltoides subsp. (usgs.gov)
  • reflects
  • The radiation of these new forms, and their expansion into new habitats in the Oligocene-Miocene, reflects the second phase in the development of fish herbivory on coral reefs that is closely associated with the exploitation of highly productive short algal turfs. (royalsocietypublishing.org)
  • ants
  • To determine whether the observed trends of gut symbionts in herbivorous ants was confounded in some way by the ants' history, we analyzed the distribution of herbivory and gut symbionts on the ant family tree-or phylogeny-and assessed how often these had evolved. (phys.org)
  • suggests
  • Fossil evidence suggests that fish-based herbivory on coral reefs was established about 50 Ma in the Eocene [ 16 ], marking the time when many modern reef fish families are first recorded in the fossil record [ 17 ]. (royalsocietypublishing.org)

  • Although herbivory is common in some groups of animals, it is rare among both extinct and extant nonavian reptiles ( 2 , 3 , 6 - 8 ). (pnas.org)
  • Although herbivory probably first appeared over 300 million years ago, it only became established as a common feeding strategy during Late Permian times. (nhbs.com)

  • emission
  • Leaves responded to larval feeding by herbivory-induced diurnal emission of semiochemicals, whereas the emission of floral volatiles remained unchanged in comparison to the noninfested control. (plantphysiol.org)
