We used museomics to reconstruct the mitochondrial genome from two individuals of the Moroccan, endemic and extinct trout, Salmo pallaryi. We further obtained partial data from 21 nuclear genes previously used for trout phylogenetic analyses. Phylogenetic analyses including publicly available data from the mitochondrial control region and the cytoc...

Background Sympatric speciation along ecological gradients has been studied repeatedly, in particular in freshwater fishes. Rapid post-glacial ecological divergence has resulted in numerous endemic species or ecologically distinct populations in lakes of the temperate zones. Here, we focus on the Baltic cisco ( Coregonus albula ) complex, to study...

Both morphological and molecular data are presented and discussed for indigenous Salmo sp. from Corsica and Sardinia, here called Tyrrhenian trout. For comparison, morphological data obtained from museum specimens, including the Algerian S. macrostigma, are discussed in the light of recent and new molecular findings. In total, 29 measurements and 2...

Abstract During the past 50 years, Fennoscandian populations of spring‐spawning Baltic cisco (Coregonus albula), sympatric to common autumn‐spawners, have declined or disappeared; for example, three out of four known spring‐spawning populations in Sweden are regarded as extinct. Over the same period, the climate has changed and populations have bee...

Presence of sympatric populations may reflect local diversification or secondary contact of already distinct forms. The Baltic cisco (Coregonus albula) normally spawns in late autumn, but in a few lakes in Northern Europe sympatric autumn and spring- or winter-spawners have been described. So far, the evolutionary relationships and taxonomic status...

Trisopterus is demonstrated to be monophyletic, including four distinct species: T. capelanus, T. esmarkii, T. luscus and T. minutus. The capelan T. capelanus is resurrected from the synonymy of poor cod T. minutus, and is shown to be morphologically more similar to T. luscus, to which species it is also more closely related, indicated by a phyloge...

Comparative morphological studies conducted on 112 specimens of Salmo from the Balkan Peninsula largely confirms earlier views of high diversity. Salmo peristericus from the Prespa Lakes basin is redescribed and diagnosed from the other Balkan species by the combination of low gill raker counts and slender body. Salmo lourosensis,new species, is de...

Two populations of softmouth trout (Salmo obtusirostris) from the rivers Neretva (Bosnia and Herzegovina) and Jadro (Croatia), along with two neighbouring populations of brown trout (Salmo trutta) were analysed with a suite of genetic markers (two mtDNA genes, two nuclear genes, and nine microsatellites) as well as morphological characters. The Jad...

There were significant correlations between colour pattern, LDH-5*, genotype and certain meristic characters in 59 hybrid trout Salmo, sp. from the Volarja stream, Soca River basin, Slovenia. It is concluded that panmixia between native Salmo marmoratus, and introduced S. trutta, of Atlantic, Danubian and Mediterranean origin had not been reached i...

Four native Salmo species are reported from Morocco and Algeria. Salmo pallaryi from Aguelman (lake) Sidi Ali is diagnosed by 12-13 (14) anal fi n pterygiophores, vs. 9-11, rarely 12 in other Salmo species. Salmo pallaryi has a unique morphology of the dermethmoid bone and resembles S. ohridanus in circumorbital bones. It is regarded as extinct sin...

Detailed morphological analysis of 76 specimens of Salmo marmoratus from rivers draining to the Adriatic Sea and 295 specimens of other Salmo species shows that it is possible to diagnose S. marmoratus from remaining Salmo species, including a marbled S. trutta from the River Otra in Norway, using colour pattern alone. S. trutta from the River Otra...
