This fits in with the general trend away from carnivory and toward herbivory that characterises mammalian evolution in many lineages. |
|
On the other hand, the dentition of the animal shows features typical of carnivory. |
|
One recurrent question concerns the extent of ape carnivory. |
|
Food habits range from strict carnivory to strict herbivory. |
|
This pattern suggests a scenario of replacement in carnivory among polyneopterous insects. |
|
It was only in the late 19th century that the carnivory of this genus began to be studied in detail. |
|
Only under such extreme conditions is carnivory favored to an extent that makes the adaptations advantageous. |
|
The extent of carnivory in brown bears has been proven to increase at northern latitudes. |
|
Among the true foxes, the red fox represents a more progressive form in the direction of carnivory. |
|
Some mammals are omnivores and display varying degrees of carnivory and herbivory, generally leaning in favor of one more than the other. |
|
In all the studied cases, carnivory allows plants to grow and reproduce using animals as a source of nitrogen, phosphorus and possibly potassium. |
|
When these conditions are not met, some plants give up carnivory temporarily. |
|
Light levels are lower than in summer, so light is more limiting than nutrients, and carnivory does not pay. |
|
Bromeliads seem very well preadapted to carnivory, but only one or two species can be classified as truly carnivorous. |
|
In this sense, bromeliads are probably carnivorous, but their habitats are too dark for more extreme, recognisable carnivory to evolve. |
|
Hence, a carnivorous plant will have both decreased photosynthesis and increased respiration, making the potential for growth small and the cost of carnivory high. |
|
True carnivory is thought to have evolved independently nine times in five different orders of flowering plants, and is represented by more than a dozen genera. |
|
Using this measure of investment in carnivory, a model can be proposed. |
|
Many plants occasionally benefit from animal protein rotting on their leaves, but carnivory that is obvious enough for the casual observer to notice is rare. |
|
The European polecat is, however, not as maximally adapted in the direction of carnivory as the steppe polecat, being less specialised in skull structure and dentition. |
|
|
For carnivory, the trait could only evolve if the increase in nutrients from prey capture exceeded the cost of investment in carnivorous adaptations. |
|
One means to maximize the benefits and minimize the costs of carnivory is the regulation of hydrolases so that they are expressed only in presence of prey. |
|
The second requirement also differentiates carnivory from defensive plant characteristics that may kill or incapacitate insects without the advantage of nutrient absorption. |
|
By some definitions this would still constitute botanical carnivory. |
|
Carnivory is the rule for softshells, but some species are omnivorous. |
|
Carnivory only pays off when the nutrient stress is high and where light is abundant. |
