It is concluded that diverse freshwater fish radiations with tropical continental distributions represent important organisms to test hypotheses of diversification and investigate the effects of palaeo-landscapes and climates on present day biodiversity.
Electric organ discharge variability of Mormyridae (Teleostei: Osteoglossomorpha) in the Upper Volta system
It is suggested that biotic environmental factors at a given location influence the expression of EOD waveforms and these factors affect absolute measurements such as EOD duration and fast Fourier transformation peak frequency as well as the amount of variation for certain waveform parameters across species in a similar manner for a given site.
Reinvestigation of the osteology of the miniature African freshwater fishes Cromeria and Grasseichthys (Teleostei, Gonorynchiformes, Kneriidae), with comments on kneriid relationships
The osteology of the three miniaturized African freshwater gonorynchiforms Cromeria nilotica, C. occidentalis and Grasseichthys gabonensis is investigated. We show that the two species of Cromeria,…
A molecular timescale for the evolution of the African freshwater fish family Kneriidae (Teleostei: Gonorynchiformes)
Two alternative relaxed molecular-clock Bayesian analyses support a Late Jurassic or Late Cretaceous origin of the African freshwater gonorynchiforms and the monophyly of the genus Cromeria.
Ontogeny and homology of the basipterygoid articulation in Pantodon buchholzi (Teleostei: Osteoglossomorpha)
It is argued that the basipterygoid articulation in osteoglossoids is homologous to that in non teleostean actinopterygians and represents a plesiomorphic character state at the level of Osteoglossomorpha.
A phylogenomic approach to reconstruct interrelationships of main clupeocephalan lineages with a critical discussion of morphological apomorphies

BackgroundPrevious molecular studies on the phylogeny and classification of clupeocephalan fishes revealed numerous new taxonomic entities. For re-analysing these taxa, we perform target gene…
Fish scale identification: From individual to species-specific shape variability

In contrast to scale identification based merely on morphology, the geometric morphometric method is capable of detecting differences in scale shape from mixed samples that are unattainable with the former approach.

Identification of past and present gobies: distinguishing Gobius and Pomatoschistus (Teleostei: Gobioidei) species using characters of otoliths, meristics and body morphometry

Otolith Fourier shape analysis proved to be most efficient in discrimination of species within both genera, Gobius and Pomatoschistus, and is proposed as a powerful tool to explore ancient goby species diversity when samples with abundant fossil otoliths are present.
Ocean warming and hypoxia affect embryonic growth, fitness, and survival of small-spotted catsharks, Scyliorhinus canicula.

Both the individual and compound effects of elevated temperature and hypoxia on the survival and growth during early ontogeny of a ubiquitous, coastal elasmobranch, S. canicula, are demonstrated.
