The Rise and Fall of Lake Tanganyika [PDF]

Quarterly Journal of the Geological Society of London, 1893
Perhaps I may be permitted to offer a few remarks concerning Mr. A. Carson's interesting paper, published in vol. xlviii, of this Journal, p. 401. That author regards the rise and fall of Lake Tanganyika as a purely local phenomenon, due to alterations of its outlet, the Lukuga, which was blocked up a long time ago, but reopened between the years 1874 ...

Trait coevolution and causal inference using generalized dynamic phylogenetic models

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1818-1836, June 2026.
Abstract Phylogenetic comparative methods are widely used to study trait coevolution across biological and cultural domains. The most common methods are phylogenetic generalized linear (mixed) models, phylogenetic path analysis, Pagel's ‘discrete’ method and Ornstein–Uhlenbeck models. While some frameworks like generalized linear mixed models are quite

Novel complete mitochondrial genomes of eight riverine Lamprologus species (Actinopterygii, Cichlidae) suggest in-situ speciation of the blind cichlid L. lethops in the lower Congo River

Mitochondrial DNA. Part B. Resources
Lamprologine cichlids include nearly 100 species from Lake Tanganyika, but only nine are known from the Congo River, including Lamprologus lethops, the only known blind cichlid. Little is known about its natural history.

Expression variations in ectodysplasin-A gene (eda) may contribute to morphological divergence of scales in haplochromine cichlids

BMC Ecology and Evolution, 2022
Background Elasmoid scales are one of the most common dermal appendages and can be found in almost all species of bony fish differing greatly in their shape.

A review of the uptake of sustainable climate‐smart aquaculture in sub‐Saharan Africa

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract As climate change reshapes agriculture and food systems across the globe, aquaculture in sub‐Saharan Africa (SSA) is at a turning point. Sustainable climate‐smart aquaculture (SCSAq) aims to make fish farming more productive, resilient to climate change, and environmentally friendly while also improving livelihoods and nutrition.

Functional Morphology of the Oral Jaws and Dentition Across Diverse Diets and Ontogeny in Prickleback Fishes (Stichaeidae)

Journal of Morphology, Volume 287, Issue 5, May 2026.
Prickleback fishes (Stichaeidae) feed upon diverse diets, spanning carnivory (orange), omnivory (blue), and herbivory (green). We used microCT scanning to explore the functional morphology of the oral jaws and dentition across species and ontogeny. Focal species vary by morphotype and have divergent scaling patterns across diets.

Tanganyika Lake, Modeling the Eco-hydrodynamics

, 2012
The model consists of a four-component ecosystem model, coupled to a hydrodynamic model. The hydrodynamic model considers the Lake as two homogeneous layers of different density lying above each other, representing the warm epilimnion (surface mixed layer) and cold dense hypolimnion (lower layer) separated by a thermocline (Naithani et al., 2002, 2003)

A new combination and typification of Pouzolzia peteri Friis (Urticaceae)

Nordic Journal of Botany, Volume 2026, Issue 5, May 2026.
Pouzolzia peteri, a lesser‐known species from the African continent, is currently classified as a member of the genus Pouzolzia. However, based on the morphological characteristics of its male flowers and leaf venation, its transfer to the genus Gonostegia is proposed.

Chloride concentrations in Lake Tanganyika: an indicator of the hydrological budget? [PDF]

Hydrology and Earth System Sciences, 2004
On a historical time scale, this paper investigates the effect of hydroclimatic variations on the surface water salinity of Lake Tanganyika, the largest African lake and an open freshwater reservoir.

An Approach for the Assessment of Climate Smart Technologies for Fisheries and Aquaculture in an Afrotropical System

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Climate variability and environmental stressors increasingly undermine the productivity and stability of fisheries and aquaculture systems across regions. Although technologies, such as recirculating aquaculture systems (RAS), integrated aquaculture–agriculture (IAA), Biofloc systems and solar powered hatcheries, have been promoted as climate ...
