1. The first organisms, which appear within a few hours of the pool forming, are bacteria, as well as tiny single celled plants and animals called algae and protozoa respectively.
2. Permanent inhabitants include many kinds of protozoa (single-celled animals) and a great many multi-celled animals, many of which undergo a daily vertical migration, from deeper to surface waters, effectively to stay within the same level of illumination as the light varies.
3. Helped by a battery of mutualistic protozoa, bacteria and fungi, they have mastered the nutritional and energetic problems of surviving in some of the poorest and most indigestible foodstuffs, from dead logs to soil humus.
4. Protozoa.
5. SINGLE-CELLED ANIMALS - PROTOZOA (Colour plate 2)
6. Scientific reference to these protozoa has been made since the early 1930's.
7. These have a key role in the body's defence mechanisms by mobilising the elements of the immune system which attack and destroy germs (foreign bodies such as bacteria, viruses, fungi and protozoa).
8. Protozoa are much larger than bacteria or viruses, although still not visible to the naked eye.
9. Numerous other predators and pathogens (viruses, bacteria, protozoa, fungi and nematodes) are also being investigated and the following are ready for evaluation in the field: Poecilia reticula and Aplocheilus spp., fish that feed on mosquito larvae; Bocillus sphaericus, a spore-forming bacterium that attacks mosquitoes; Culicinomyces clavosporus , a fungus that kills mosquitoes; and Romano- mermis culicivorax , a nematode worm that inhabits and kills mosquito larvae.
10. The disease is caused by unicellular parasites (protozoa) of the genus Plasmodium that undergo cycles of development in both man and the mosquito.
11. A large and heterogeneous collection of organisms are grouped in the Protozoa, including all those animals that can lead an autonomous existence as a single cell.
12. Fungus is rarely a primary invader of the fish, only occurring in the later stages of disease when fish are heavily infected by protozoa, flukes and bacteria.
13. One group that disappeared was the fusulinids, complex protozoa that ranged from the microscopic to two or three inches in size.
