Autor: Graeme Patterson, John D. Halfman, John M. Edmond, David H. Eccles, Ray F. Weiss, Harvey A. Bootsma, Robert E. Hecky, Martin K. Vollmer

Publikováno v: Limnology and Oceanography. 50:727-732

We use historic water temperature measurements to define a deep-water warming trend in Lake Malawi, East Africa. Over the past six decades, the temperature of the deep water below 300 m has increased by ~0.7°C. The warming trend is due mainly to the

Cichlid spawning structures – bowers or nests?

Autor: David H. Eccles, Rosemary Lowe-McConnell, Denis Tweddle, Peter B. N. Jackson, Geoffrey Fryer, Digby S C Lewis, Clifford B. Frith

Publikováno v: Environmental Biology of Fishes. 51:107-109

Males of mouthbrooding cichlids build sand-castle or sand-scrape structures. These are used as display sites to attract females, eggs are laid and inseminated there and then taken away by the female for brooding elsewhere. It has been suggested that

MASS MORTALITIES OFLATES(PISCES: CENTROPOMIDAE) IN LAKE ALBERT

Autor: David H. Eccles

Publikováno v: Journal of the Limnological Society of Southern Africa. 2:7-10

SUMMARY Parker attributed a mass mortality of Lates in Lake Albert to the shock effect of an earthquake which occurred at the same time. A consideration of the limnology of the lake and of limitations to the ability of fish to adjust their buoyancy s

Autor: David H. Eccles, Digby S C Lewis

Publikováno v: Zoological Journal of the Linnean Society. 58:165-172

The definition of the genus Docimodus is revised so that it can accommodate an additional species. The description of the type species D. johnstonii is expanded and a new species, D. evelynae, described and illustrated. Examination of stomach content

An outline of the physical limnology of Lake Malawi (Lake Nyasa)

Autor: David H. Eccles

Publikováno v: Limnology and Oceanography. 19:730-742

Lake Malawi, in tropical central Africa, is 560 by 75 km and consists of a single basin, maximum depth 695 m. Below 250 m the lake is homothermal at about 22.5°C and is anoxic. Above this level there is a seasonal cycle with the development of a mar

Lake flies and sardines—A cautionary note

Autor: David H. Eccles

Publikováno v: Biological Conservation. 33:309-333

Turner (1982 b ) considered that the presence of Chaoborus in Lake Malawi and its absence from Lake Tanganyika implies that the clupeid fishes of the latter are more efficient zooplanktivores than the fishes in Lake Malawi. He suggested that in lakes

Is speciation of demersal fishes in Lake Tanganyika restrained by physical limnological conditions?

Autor: David H. Eccles

Publikováno v: Biological Journal of the Linnean Society. 29:115-122

Both Lake Malawi and Lake Victoria have many species of offshore demersal cichlids, most of which are stenotopic. In Lake Tanganyika there are fewer, more eurytopic, demersal species. These differences may be the effect of the physical regimes of the

Midwater spawning inHaplochromis chrysonotus (Boulenger) (Teleostei: Cichlidae) in Lake Malawi

Autor: David H. Eccles, Digby S C Lewis

Publikováno v: Environmental Biology of Fishes. 6:201-202

Haplochromis chrysonotus, a semipelagic shoaling cichlid from Lake Malawi, has been observed spawning in open water up to ten metres above the substratum. It is suggested that open water spawning without the establishment of a substratum-based territ
