Historical Drainage Evolution and Water Level Fluctuations in the African Great Lakes Shaped Phylogeny and Biogeography of Freshwater Gastropods

open access: yesJournal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim The role of historical drainage connectivity and the influence of water level fluctuations in African lakes on the evolution and distribution of macroinvertebrates remain poorly understood. This is partly because evolutionary biology research has largely focused on mobile vertebrates, such as cichlids.

Nile Tilapia (Oreochromis niloticus L.) Cage Aquaculture in Africa: Potential Threats to Congeneric Fish Species and Advances to Detect Escapes

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Cage fish farming, a recent development in aquaculture, has enhanced fisheries production due to its higher stocking densities than traditional pond and open‐water systems. Although it can enhance production, the system can pose biodiversity threats when there is an unintentional or intentional release of stocked fish into the wild.

Time poetics and ageing in the Ik mountains: seeing time disappear Poétique du temps et vieillissement dans les montagnes des Iks : voir le temps disparaître

open access: yesJournal of the Royal Anthropological Institute, Volume 31, Issue S1, Page 73-90, April 2025.
In the Ik mountains in Uganda, only few old people still have the skills to ‘see time’ with sundials. Common ways of knowing time and age now include phones and ID cards in digital registers. I follow the elder seer Komol to explore how changing the measures of time influences the experience of time and age. How do being a ‘time being’ and ideas about ‘

Dominance-as-markedness

open access: yesStudies in African Linguistics, 2019
This paper examines a formal consequence of the assumption that dominance is equivalent to markedness (Casali 2016): if dominant ATR values are marked and therefore specified, while recessive values are unmarked and unspecified, then no phonological ...

Evaluation of Productivity and Profitability of Integrated Nile Tilapia (Oreochromis niloticus Linnaeus, 1758) and Swiss Chard (Beta vulgaris L. var. cicla) Production

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
The growth of the human population requires the establishment of additional food‐producing sectors to meet the increasing demand for animal protein sources. In this context, integrated fish farming presents a viable option for enhancing yield diversification with minimal investment costs. The objective of this study was to evaluate the productivity and

On whether 'Doboro' was a fourth Kuliak language

Wayland’s (1931) description of a northeastern Ugandan people called the ‘Wanderobo’ includes thirty-eight ‘Dorobo’ words, many of which resemble words in Ik, the last thriving member of the Kuliak (Rub) subgroup. Because of this resemblance, it has been

Medicine among Nilotics in the Sud. [PDF]

open access: yesBMJ, 1981
"So you are going to Ler. Well, I wish you luck. I don't know how the doctor stands it out there. It's the fly capital of the world," the pilot remarked cheerfully to me as we took off in a small single-engine plane. He was taking me, together with the fortnightly supply of food, drugs, and mail, to the American couple living there.

The African introgression of Murciano Granadina goats has a Moroccan origin and displays remarkable levels of inter‐individual variability

open access: yesAnimal Genetics, Volume 55, Issue 6, Page 843-848, December 2024.
Abstract There is evidence that Murciano Granadina (MG), the most important caprine dairy breed in Spain, has been introgressed by African goats, but the precise geographic origin of such introgression has not been identified yet. Moreover, an accurate estimate of the magnitude of this African introgression is lacking, since current estimates are based
