1, Goldfish are particularly prone to predation by cats and birds such as herons.

2, Some trait must provide them with immunity from predation.

3, Their colour pattern will then protect them from predation.

4, The effects of this predation could be devastating.

5, Predation concentrated on individual whelks feeding on the open rock surface.

6, But it does endure its share of predation by man.

7, Within one generation, the predation rate drops to the level found in areas where the animals have long co-existed.

8, Furthermore, the importance of predation can be seen as yet another element in the disturbance picture.

9, This is an adaptation to survive predation from the many animals that hunt them - not least man for the cooking pot!

10, Below low water mark, predation by lobsters may be significant.

11, The birds whose selective predation put the finishing touches to their evolution must, at least collectively,(http://sentencedict.com/predation.html) have had excellently good vision.

12, In relatively benign environments, predation is the dominant biological interaction that structures communities. 2.

13, Loss of beachfront habitat and predation by domestic cats and introduced red foxes pushed the least tern to the brink of extinction.

14, It is a reflex born of predation by voracious crabs that nip at the tender tubeworm plumes with their claws.

15, The step from predation to this symbiosis is a short one.

16, Some of these isolated populations are subject to predation, others to starvation, flooding, severe winters or summer drought.

17, Even without ageing, organisms are at risk of death and impaired fertility from disease(sentencedict.com), predation and accidents.

18, In these species mating occurs in early spring and rapid breeding may be an adaptation to avoid predation.

19, Predation One of the major causes of mortality in small mammals is predation.

20, Under natural conditions some bands die out due to severe drought, disease, or increased predation.

21, All these spikes evolved originally as a way of preventing predation by larger fish.

22, Once poison has temporarily reduced rat populations to almost zero, predation by barn owls can slow the recovery.

23, It would therefore appear that the ensuring of successful pollination must override the importance of losses due to seed predation.

24, In contrast to this, extrinsic factors like food supply and predation are held by other workers to control the population cycles.

25, Hamilton gave some entertaining examples of animals attempting to escape predation by clumping.

26, This odd reversal of polygyny has been attributed to a very high rate of ground predation whereby clutches are easily lost.

27, This was treated in general terms in Chapter 1 and with specific regard to predation in Chapter 2.

28, The abandonment of trees makes the species, especially the young, prone to ground predation.

29, Perhaps this synchronous transformation is the means by which the toads limit predation by their own kind.

30, At this stage immediately after metamorphosis, they are vulnerable to another unexpected source of predation.
