Lake George, Uganda, lies on the equator and shows little variation in temperature or in the dominance of Microcystis in the phytoplankton. The dominant planktonic rotifers in Lake George are compared to those found in lakes in other parts of the world, ranging from tropical and subtropical lakes with semi-permanent blooms of Microcystis to tempera...
Article
Lake Sonfon lies in an isolated basin in the Sula Mountains of Sierra Leone. One hundred and two animal taxa were collected from this lake in April 1976: 78 of these have been identified to species, and all but four as far as the genus. The fauna consists mainly of animals with extensive geographical distributions, indicating that they have wide di...
Article
The freshwater medusa Limnocnida victoriae was found from December 1956 to April 1957 in a pool which becomes separated from the main channel of the River Sokoto during the dry season. The medusae are described and the importance of the number and size of statocysts as a systematic character within the genus is discussed. A map showing the distribu...
Article
Of the two Balinese lakes revisited in 1974, 45 years after an earlier survey, the unproductive Danau Bratan, with a very low conductivity, showed changes in water chemistry and plankton composition that may reflect slight cultural eutrophication. Danau Batur, a larger lake with a very high conductivity, showed little change since 1929. Danau Brata...
Article
Rhizorhina ampeliscae Hansen is recorded from Guernsey and the Clyde area. Five species of the genus Sphaeronella are recorded from British waters for the first time. One of these, S. pikei, is a new species. Sphaeronella elegantula Hansen is shown to be a synonym of S. leuckarti Salensky. The larva of S. danica and the male of S. longipes are desc...
Article
Zooplankton associations in six crater lakes have been compared by means of indices of similarity and diversity, and by k-dominance curves. The lakes covered a wide range of salinities and vegetational characteristics. The total number of species identified were: Protozoa, 34; Rotifera, 48; Gastrotricha, 7; Crustacea, 24; and Chaoborus larvae, 2; g...
Article
Simocephalus vetulus (O. F. Müller) is coloured by carotenoids, which may befree in globules in the gut wall and fat body, or associated with proteins in the cytoplasm of the fat cells, carapace epidermis, ovary and eggs. A green carotenoprotein is foundin the blood. The transfer of carotenoids from one tissue to another is described; these pigment...
Article
Forty-one species of Rotifera are recorded from the River Sokoto, North Nigeria, and details of their seasonal abundance are given. There is a marked change in the composition of the rotifer fauna of the river when it floods in the single wet season. The cyclomorphosis of Keratella tropica begins with the appearance of the species in December. At t...
Article
The planktonic Rotifera are not all cosmopolitan in their geographical distribution. There is a latitudinal variation in the assemblage of planktonic species. Most of this variation can be attributed to species in nine genera, of which some (e.g. Brachionus) are more abundant in warm areas, and others are more abundant in cool areas (e.g. Notholca)...
Article
Plankton samples for rotifers were collected by means of vertical hauls with phytoplankton nets at eight stations on Lake Albert during the course of a year. Similar hauls were taken from Lakes Kyoga, Victoria, George and Edward in October and November. The rotifers found in the samples are listed and some estimates of their abundance and seasonal...
Article
In July 1974 Ranu Lamongan overturned. The resulting deoxygenation of this small tropical crater lake killed some of its fishes. This paper describes the recovery of stratification of temperature and oxygen and follows short-term changes in the plankton during the three weeks after overturn. The lake is fringed with a floating mat of Eichhornia who...
Article
The West Cameroonian crater lake Barombi Mbo is stratified, with no detectable oxygen below 20 m. Of the endemic cichlid fishes in this lake Konia dikume is exceptional in having a mean haemoglobin concentration of 16.55 g/100 ml, while the other ten endemic cichlids range from 5.55 to 8.70 g/100 ml blood. The erythrocyte count is also higher in K....
Article
Thirty-one species of Cladocera are recorded from the lake sources of the White Nile. An account is given of the seasonal occurrence of the main planktonic species at eight stations in Lake Albert. The horizontal distribution of species in Lake Albert was studied by means of vertical hauls taken at intervals along the length of the lake, and along...
Article
Thirty-two species of testaceous Rhizopoda have been identified from the plankton of the River Sokoto. Most of these species are adventitious in the plankton, and are most abundant in the wet season when the river is in flood. Four species: Arcella vulgaris, Difflugia limnetica, D. lobostoma and Centropyxis aculeata occur regularly in the plankton...
Article
The horizontal distribution of the zooplankton in Lake Kariba was sampled by means of vertical hauls using 55 and 250 μm meshed nets. Crustacea were sparse in the main lake, but increased dramatically in the very shallow water at the end of Crocodile Creek. The composition of the zooplankton is influenced by the presence in the main lake of the Tan...
Article
The mouthparts of Mesidotea entomon are briefly described. Observations on living animals show that this species is capable of locating and capturing active animals, both on the surface of the substratum and below the surface. The feeding mechanisms of Mesidotea and Chiridotea are compared; it is suggested that the rhythmic packing action of the gn...
Article
Two lakes lie in a caldera at the top of Jebel Marra. One is shallow and highly saline, with a dense bloom of planktonic blue-green algae and a zooplankton consisting entirely of rotifers. The other is over 100 metres deep, is less saline, with a sparse phytoplankton of diatoms, and the dominant zooplankter is Eucyclops gibsoni. The marginal fauna...

Fifty-one species of Crustacea are recorded from plankton samples taken from the Sokoto river system. The following new species are described; Alona. holdni, Microcyclops pseudo-anceps, Cyclopa gauthieri, Phyaocypria minicapensis. An account is given of the seaaonal occurrence of each species in the main channel of the river and in a pool which bec...
Article
The zooplankton of four crater lakes in North-west Cameroon has been studied by means of vertical hauls from the bottom to the surface. Two of the lakes are deep, with sparse phytoplankton, while the other two are shallow with dense blooms of blue-green algae. All the lakes are without planktonic Cladocera. In Lake Kotto, Mboandong and Barombi Mbo...
Article
Quantitative samples of zooplankton from three lakes in the Kigezi District of Uganda have been studied. The systematics of the zooplankton are considered, and some of the identifications given by Worthington & Ricardo (1936) in a previous study of one of these lakes are revised. Lake Mulehe is the shallowest of the three lakes and contains the lar...

The male and female of Rhizorhina serolis sp. n. are described and figured. This copepod is parasitic on the isopod Serolis bromleyana, from Chatham Rise, between Chatham Island and New Zealand. Sphaeronella serolis Monod is recorded from the same host and locality. The hitherto unknown larva and male pupa of S. serolis are figured. The male of Rhi...
Article
African catfish of the genus Synodontis vary in their habits, from inverted plankton eaters to normally oriented benthos eaters. Haemoglobin concentrations and red cell counts vary between populations of one species, and between species of differing habits. Synodontis schall from the well-aerated White Nile had lower haemoglobin concentrations than...
Article
A new species of halacarid mite of the genus Limnohalacarus is described from Ranu Lamongan in East Java.
Article
The nauplius of Dactylopusioides macrolabris (Claus) is described and figured. The second antenna is modified to form a biting appendage, while the mandibles are not capable of biting. The nauplii and an associated adult female were found in galleries in the fronds of the brown alga Dictyota dichotoma, from Torquay, Devon. This is the first British...
Article
Associations of rotifers in 12 Australian crater lakes have been compared by means of indices of similarity and diversity, and by two dimensional ordination.

The specific composition and diversity of the zooplankton in 18 impoundments in Zimbabwe were analysed on the basis of samples taken in July and August 1983. All the lakes lay at altitudes over 1200 m, with the highest at 2270 m. Thirty species of Rotifera and 20 species of Crustacea were identified, but the mean numbers of species per lake were 5·...
Article
.1 In natural populations parthenogenetic egg production in Daphnia magna Straus is directly related to size.2 Previous workers have shown that the number of parthenogenetic eggs produced during the life of a female increases in the early broods and decreases in later broods.3 Egg production and size are positively correlated in the first adult ins...
Article
In Lake Albert Daphnia lumholtzi is found in two forms. One has a pointed anterior prolongation, or helmet, on the head. The other has a shorter rounded head, and was originally described as a separate species, D. monacha. The latter form dominates the zooplankton in the middle of the lake where planktivorous fish are rare or absent. The helmeted f...
Article
Lake Kyoga is a complex, shallow lake, which breaks into satellite lakes in the east. The eastern end receives inflows from Mount Elgon and the northern province of Karamoja. The main inflow to the western part of the lake comes from Lake Victoria. The outflow falls over 400 m before joining the outflow from Lake Albert. The vegetation is complex,...
Article
The bird fauna of the Nile ranges from cosmopolitan species, such as the Osprey (Pandion haliaetus) and Moorhen (Gallinula chloropus), to endemic species with limited distributions, such as the Blue-winged Goose (Cyanochen cyano-pterus), which is confined to the Ethiopian uplands. There are great differences in the status of birds of different fami...
Article
The nilotic lakes associated with the Western Rift are separated from the more southerly lakes Kivu and Tanganyika by the Virunga volcanoes. They include three small lakes in the Kigezi highlands, and three large lakes, George, Edward and Albert in the valley. The small lakes have poor fish faunas (mostly introduced), and have shown major changes i...
Chapter
The Sudd swamps developed from a large lake which extended north to Khartoum during the Pleistocene. The main channels are stable over decades, but the bends show upstream migrations of about 20 m in 3 years. In permanent swamps the channels often have a band of Vossia, backed by papyrus, which in turn is backed by an extensive area of Typha doming...
Article
In July and August 1988 samples of zooplankton were collected from 17 lakes on four islands. Five species of Cladocera, three species of Copepoda and 30 species of Rotifera were found. The maximum numbers of species in any one lake were four planktonic Cladocera, two Copepoda and seven planktonic Rotifera (with up to six additional non-planktonic s...

The morphological variation of Keratella cochlearis in a Thames backwater has been studied over 4 years. There was a general inverse relationship between lorica length and temperature, but the annual cycle of change depended upon the rate of change of the temperature, and there was considerable variation between years. There was a similar inverse r...
Article
Freshwater medusae of the genus Limnocnida were found in a shallow lake in the floodplain of the Ayeyarwaddy River. The medusae are described and identified as a small form of L. indica. Single immature specimens were found in two other localities in Myanmar, within the Ayeyarwaddy catchment. These records are an eastward extension of the known ran...

The little-known prepleistocene Lake Indawgyi (Myanmar) is shown to harbour an endemic pelagicEodiaptomus species, described herein. The area around the lake is inhabited by another species in the same genus. Related species occur throughout South-East Asia, and a presumed close relative is endemic to a chain of pre-pleistocene lakes in Celebes.
Article
The Okavango Delta has an annual flood cycle that spreads slowly from the northwestern`panhandle' into a widening delta to the southeast. Rotifers were sampled from areas where the flood was active, and from other areas not yet reached by the flood. In still waters, the samples were dominated by euplanktonic rotifers, particularly of the genera Bra...
Article
Seventeen localities over a 1500 m altitudinal range were sampled in January 1991 and October 1992 in the subtropical highlands of Lesotho, southern Africa. Spatial and temporal variability in rotifer assemblages are described briefly, and factors driving community heterogeneity are considered. Predation was identified as one significant factor; so...
Article
The volume of a single amictic egg of Keratella cochlearis can vary between 32 000 and 132 000 m3. Much of this variation is related to the size of the female laying the egg. When compared to populations in Europe, those in the Southern Hemisphere (Southern Africa and New Zealand) show a smaller increase in egg volume per unit increase in lorica le...
Article
Samples were taken from a Malaysian estuary along a salinity gradient from full strength sea water down to a conductivity of 27 µS cm−1. In a region where the conductivity fluctuated between 6500 and 14000 µS only empty loricas of Keratella cochlearis and Lecane bulla were found. Where the salinity reached a maximum of 3800 µS Lecane bulla was the...
Article
The altitudinal distributions of planktonic Cladocera in Africa in three latitudinal bands: 0–10 °, 10–20 ° and 28–31 ° are described. Some species have altitudinal ranges of 2000 m within a latitudinal band of 10 °. It is possible to distinguish tropical species which do not extend up to high altitudes, particularly at higher latitudes. At the low...
Article
Many flagellates, ciliates and rhizopods appear to be cosmopolitan, at least when considered at the morphospecies level. There are indications of tropical endemics among the ciliates and the rhizopods, but the percentage of endemics appears to be low. Among the rotifers there is a well marked latitudinal gradient, but the picture is complicated by...

Abstract The Zooplankton of 38 East African lakes has been analysed in terms of species richness and dominance. The conductivities of the lakes range from 48 to 72 500 μ S cm-1 20 °C. The lakes generally contain more species of rotifers than either Copepoda or Cladocera. The number of species of rotifers begins to decline at a conductivity below 10...
Article
The diversity of planktonic species in a body of water can be estimated in two ways: momentary diversity and long term diversity. The former represents the number capable of coexisting at any one time, and the latter includes a seasonal or other temporal component. The relationship between the two varies mainly with salinity. Dominance is generally...

The communities of planktonic Rotifera in thirty localities in Ethiopia were examined. All the localities lay at altitudes of over 1100 m and some were over 2000 m. The salinities ranged from 0.12 to 56.3% and in those lakes with salinities over 2% there was a marked reduction in the number of rotifer species, with Brachionus dimidiatus the most fr...
Article
The species composition of rotifers in Lake Awasa was studied and 40 species recorded. Seven species appeared in large numbers in the plankton seasonally. Brachionus and Keratella species made up more than 50% of the rotifer community by numbers during the observation period (1983–1987). The standing stock numbers of rotifer species are low with a...

Article
Samples from the main Nile channel yield a poor zooplankton, deficient in species and heavily laden with organic debris. Samples from side arms and floodplain lakes yield a richer zooplankton, often containing 15–20 species of rotifers and ten or more species of Crustacea. When the floodplain lakes are heavily vegetated the number of species increa...
Article
Limnohalacarus africanus and L. fontinalis are recorded from Lake No. These are respectively the third and second records of these species, and represent considerable extensions of their known ranges.
Article
In July 1980 samples of the rotifer Keratella cochlearis were taken from ten lakes ranging in altitude from 630 to 1244 in above sea level. The total period of sampling was short enough to ensure that seasonal effects were negligible. The mean lorica length and mean posterior spine length showed a positive relationship with lake altitude. This indi...
Article
Keratella tropica usually has two posterior spines. Both may vary in length, but the left is always shorter than the right. Sometimes the left spine is absent. Spine length varies with the length of the lorica, but there are other, external, influences. Three separate lines of evidence indicate that factors which promote spine length are related in...
Article
Samples taken from Lake Mutanda in 1975 indicate that the specific composition of the zooplankton has changed from that in 1962. This change is very similar to that which occurred in Lake Bunyonyi sometime between 1931 and 1962. The most important aspect of the change is the disappearance of three species of Daphnia, together with Ceriodaphnia reti...
