Examples

1. ‘Cyprinids and sticklebacks are similar in body size but differ in their degree of body armor.’
2. ‘In the open water
3. long spines help protect the stickleback from being swallowed by large predators.’
4. ‘The diverse genes hypothesis is supported by a study of sticklebacks.’
5. ‘The oil slick contaminated about three kilometres of waterway killing about 150 sticklebacks - small fish renowned for being tolerant to pollution - a seagull and a duck.’
6. ‘Although Daphnia are not used by humans as a food source directly
7. they are involved in many of the foodchains necessary to sustain fish that we consume or use commercially such as sticklebacks
8. minnows and young Sockeye salmon.’
9. ‘In the spring the water was filled with sticklebacks and frogspawn - enough to delight any youngster and he would catch them in a small net and take a few home in a glass jar.’
10. ‘For example
11. in a study of more than 25 populations of sticklebacks
12. all adaptive behavioral differentiation appears to have occurred by loss of ancestral behavior patterns or by shifts in the frequency of their expression.’
13. ‘Familiarity develops over a period of time; in both the guppy and the stickleback
14. it develops gradually over approximately 2 weeks.’
15. ‘Examples include the red markings of salmon
16. stickleback
17. and guppies
18. in addition to many birds.’
19. ‘Some researchers believe that the two lineages of marine and freshwater sticklebacks are an example of evolution in action
20. since records indicate that some of their adaptations have occurred in only the past 10 years.’
21. ‘Such video techniques have been particularly effective in female mate choice studies in fishes
22. including guppies
23. sticklebacks
24. and swordtails.’
25. ‘In a certain new pond in Bergen
26. Norway
27. during the past century
28. sticklebacks evolved toward the lighter armor in just thirty-one years.’
29. ‘For example
30. individual male sticklebacks that are bolder toward predators are also better at obtaining breeding sites through territorial aggression.’
31. ‘There are also rudd
32. bream
33. eels
34. gudgeon
35. crucian carp
36. tench
37. minnows
38. perch
39. the odd trout
40. pike and barbel present.’
41. ‘The three-spine stickleback is a fish known for its tremendous variability in size
42. physiology
43. and behavior.’
44. ‘Boxfishes and three-spine sticklebacks hover very well by oscillating their pectoral fins with large attack angles on both recovery and power strokes.’
45. ‘For example
46. in sticklebacks
47. a large fish distracts predator attention from the smaller ones
48. and an individual may decrease its risk of predation by locating close to a more preferred prey.’
49. ‘Further evidence that the several instances of beach spawning in fishes arose by different mechanisms comes from puffers and sticklebacks.’
50. ‘More than 250 people around the world are observing and documenting evolution
51. not only in finches and guppies
52. but also in aphids
53. flies
54. grayling
55. monkeyflowers
56. salmon
57. and sticklebacks.’
58. ‘Although most species of stickleback can adapt to salt
59. brackish
