Geographic and Genomic Signatures of a Dynamic Evolutionary History in Lake Tanganyika's Synodontis Catfish Radiation

open access: yesJournal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim Lacustrine systems generally exhibit greater habitat stability than riverine systems, yet some lakes have experienced substantial lake‐level fluctuations throughout the Pleistocene. These environmental perturbations repeatedly altered habitat availability critical to the evolution of their diverse fish communities.

Seasons and seasonality in lakes: A synthesis amid global change

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Seasonality in environmental conditions plays a fundamental role in shaping lake ecosystems. However, patterns of seasonality vary worldwide, and these patterns are shifting over time amid global change. Thus, it is increasingly important to evaluate how seasons and seasonality are represented in lake ecosystem research.

The Savage Worlds of Henry Drummond (1851–1897): Science, Racism and Religion in the Work of a Popular Evolutionist

open access: yesJournal of Religious History, Volume 50, Issue 1, Page 77-95, March 2026.
The savage was a familiar as well as deeply problematic figure in late‐Victorian literary and scientific imaginaries. Savages provided an unstable but capacious and flexible signifier to explore human development and human difference, most often in ways that followed a disturbing racial logic.

Catfishes from the North-Western Part of Lake Tanganyika: Contribution to a Reference Library of DNA Barcodes

open access: yesDiversity
In spite of the global barcoding effort, there is still a lack of genetic data on African freshwater fishes. We aimed to contribute to bridging this gap by providing molecular data on commercially important catfish species from the north-western part of ...

Trophic Niche Differentiation and Mercury Levels in Cyphotilapia frontosa and C. gibberosa Along the East Coast of Lake Tanganyika

open access: yesFishes
Diet, trophic niche, and mercury were examined for Cyphotilapia frontosa and C. gibberosa along the east coast of Lake Tanganyika, from northern Burundi to the southern region near the Zambian border. Mercury levels were generally low across populations,

open access: yesBMC Evolutionary Biology, 2006
Background Squeaker catfishes (Pisces, Mochokidae, Synodontis) are widely distributed throughout Africa and inhabit a biogeographic range similar to that of the exceptionally diverse cichlid fishes, including the three East African Great Lakes and their ...
