J.J. Wright og L.M. Page har her i år lavet en taksonomisk revision af Synodontis arterne i Tanganyika søen. Der skulle findes en pdf. fil et sted omkring det. Jeg kan bare ikke lige finde den.

Ved du hvilket tidskrift det er publiseret i ?

Jeg har kun følgende oplysninger: (Siluriformes: Mochokidae). Florida Mus. Nat. Hist. Bull. 46(4):99-154.
Jeg ved ikke om det kan bruges? 🙂

jeg fandt det lide Bulletin Florida Museum Natural History v. 46, no. 4, pp. 99-154. ja det bliver nok lidt besværligt at skaffe :e :e

He he...ja, det var de eneste oplysninger som jeg umiddelbart kunne se 🙂

Er det den her?

On the origin of the Synodontis catfish species flock from Lake Tanganyika

Abstract:
Species flocks within Great Lakes provide unique insights into the factors affecting diversification. Lake Tanganyika (LT) is of particular interest because it contains many endemic groups for which general factors affecting diversification can be discerned. Here, we present the first phylogenetic study of the LT Synodontis (Siluriformes, Mochokidae) species flock using mtDNA sequence data. Our data reveal some previously unrecognized species diversity and indicate that the LT species flock is not monophyletic, and that two closely related clades of endemics may have independently colonized LT. Other comparable small species flocks are characterized by a single colonization event. Molecular date estimates of the timing of the initial within-lake diversification of the LT endemics, based on a fossil calibration, are comparable to those reported for other groups, suggesting that extrinsic factors maybe important common causes of clade diversification. The basal divergence in the sampled Synodontis reveals an East?West African faunal split seen in many terrestrial, but few aquatic groups, the timing of which coincides with East African rifting events.

Tusind tak 🙂

#6 jeg har lige downloadet den (Super artikel tusind tak), men det er ikke den samme som #4 og #5. tidskriftet "Bulletin Florida Museum Natural History" tilgængeligt på universitets biblioteket. For dem der er interesseret kan en fotokopi bestilles på det lokale bibliotek.
