Voorbeelden van tadpole

• Anti-predator defence mechanisms may have evolved during the process that enabled these tadpole species to occupy large permanent streams, which often shelter predatory fishes.

• In sites where visibility was too poor for observation of tadpoles, such as areas with submerged aquatic vegetation, microhabitats were sampled with a small dipnet.

• Females construct underground nests, typically at the beginning of the rainy season before temporary ponds fill, in which they oviposit and attend eggs and tadpoles.

• Dendrobatids with terrestrial oviposition and subsequent parental tadpole transportation were continuously active.

• The role of adult anurans in choosing oviposition sites may also influence the distribution of tadpole species among streams.

• We investigated the correlation between calling activity, rainfall, temperature and water level in two ponds and recorded the occurrence of tadpoles of pond-breeding species.

• In the third axis, larger values indicate use of deeper microhabitats by tadpoles.

• Tadpoles were counted and the number of tadpoles per sweep calculated.

• Most ascidian species exhibit indirect development in which the egg develops into a tadpole larva.

• Eggs and tadpoles were reared to metamorphosis in buckets of stream water to confirm species identification.

• In this situation, oncomiracidia are available to infect tadpoles during the brief period of the rainy season.

• Pond tadpoles with generalized morphology: is it time to reconsider their functional roles in aquatic communities?

• This would imply indiscriminate use of available niche space by tadpoles, with no other factor limiting their distribution.

• They multiply enormously in the crop, undergoing a great change in appearance, being tadpole-like in form and having a crithidia-like arrangement of the nuclei.

• Freshly hatched tadpoles had a prominent yolk sac, the contents of which were rapidly used up during the first few days of development.
