  • He found that Venus flytraps experience a 90 percent decrease in moderate-sized cricket prey capture success when marginal spikes are removed. (phys.org)
  • We provide the first direct test of how prey capture performance is affected by the presence of marginal spikes, trichomes that provide a novel function in Venus flytraps by forming what Darwin described as a 'horrid prison,'" Davis writes. (phys.org)
  • For the laboratory portion, Davis and his coauthors assembled "prey capture arenas," wherein 34 Venus flytraps were set up in planters with "on ramps" for crickets. (phys.org)
  • What they're trying to do is capture nitrogen and phosphorus from their prey. (scientificamerican.com)
  • Nutrient analyses showed that both crab spiders also decreased per unit nitrogen yield of prey. (springer.com)
  • Our findings suggest that any nutritional mutualism that increases the quantity of resource capture (e.g. number of prey individuals) but decreases the quality of the captured resource (e.g. nitrogen content of individual prey) will necessarily conform to the resource-based predictions of the stress gradient hypothesis. (springer.com)
  • Though generally of small body size, it is likely that they incorporated vertebrate prey into their diet and thus represent an early assay into mammalian carnivory. (digimorph.org)
  • Diatom sequence reads were frequent and abundant, indicating a largely diatom-based diet, while the occasional presence of high abundances of copepod sequence reads suggests carnivory supplemented the diet. (int-res.com)
  • Black snakes were only able to prey consistently on cane toads once they had evolved behavioral and physiological traits that enabled them to cope with such prey. (biologists.org)
  • Although this ecological scenario suggests potential fitness benefits to be gained from a carnivorous diet, especially when resources are limited, multiple characteristics are needed to sense, obtain, digest and assimilate nutrients from such prey. (biologists.org)
  • Canines are excellent for stabbing and holding prey as the upper ones point almost straight down and the lower ones are curved. (animaldiversity.org)
  • The feeding apparatus of the ancestral gnathostome relied on the scissor-like action of the upper and lower jaws to bite and hold prey. (umd.edu)
  • A long snout with which prey is disabled before being picked up in the jaws. (umd.edu)
  • During the Cambrian explosion, animals not only started to eat meat, such as drifting plankton, but they also developed jaws for grabbing and chewing bigger prey. (scientificamerican.com)
  • At high temperature (18-20 °C) and high prey density (≥1000 prey m-2) one large adult D. villosus consumed 6-9 prey day-1 on average while one G. roeselii consumed 4-7 prey d-1 and one smaller D. villosus of a length of 8-10 mm consumed 2-5 prey d-1 while one G. roeselii of the same length consumed 3 prey d-1.

  • Given their large body size and carnivorous lifestyle, we would predict that northern elephant seals ( Mirounga angustirostris ) have elevated field metabolic rates (FMRs) that require high prey intake rates, especially during pregnancy. (biomedcentral.com)
  • These effects often benefit populations of native prey, and diversity and biomass of vegetation, but may not occur under all circumstances. (deepdyve.com)
  • We compared feeding rates of the well-established, non-invasive amphipod Gammarus roeselii with those of the invasive Dikerogammarus villosus at different prey densities and different temperatures in laboratory experiments using chironomid larvae as prey. (jlimnol.it)
  • The trapping mechanism is tripped when prey contacts one of the three hair-like trichomes that are found on the upper surface of each of the lobes. (wikipedia.org)
