Lake Tanganyika--a 'melting pot' of ancient and young cichlid lineages (Teleostei: Cichlidae)? [PDF]

open access: yesPLoS ONE, 2015
A long history of research focused on the East Africa cichlid radiations (EAR) revealed discrepancies between mtDNA and nuclear phylogenies, suggesting that interspecific hybridisation may have been significant during the radiation of these fishes.

Geographic differentiation of ectoparasitic flatworms in the pelagic zone of Lake Tanganyika, Africa [PDF]

open access: yesFrontiers in Zoology
Monopisthocotylan parasites have been proposed as tags for studying host population structure due to their direct life cycles and short generation times. However, their effectiveness in reflecting host population connectivity remains under scrutiny.

Nonapeptide molecular evolution during the adaptive radiation of Tanganyika cichlids. [PDF]

open access: yesJ Neuroendocrinol
Abstract Oxytocin (OT) and vasotocin (VT) are evolutionarily conserved nonapeptides that regulate a wide range of physiological and behavioral processes in vertebrates. Their receptor families have undergone gene duplications that facilitated functional diversification throughout vertebrate evolution.

Century-to-millennial scale climatic variability in Lake Malawi revealed by isotope records [PDF]

open access: yes, 2007
Diatom-based oxygen isotope data (δ18Odiatom) from Lake Malawi show multi-centennial scale wet–dry intervals spaced approximately every 2.3 ka throughout a 25 ka sequence.
