CLADOGENESIS AND LOSS OF THE MARINE LIFE-HISTORY PHASE IN FRESHWATER GALAXIID FISHES (OSMERIFORMES: GALAXIIDAE) [PDF]
Evolution, 2007 Switches from migratory (diadromous) to nonmigratory (freshwater) life histories are known to have occurred repeatedly in some aquatic taxa. However, the significance of the loss of diadromy as an initiator for speciation remains poorly understood. The rivers of New Zealand's South Island house a species flock of recently derived nonmigratory galaxiid ...

Comparative Parasitology, 2008 Brachygalaxias bullocki (Regan, 1908) is a fish species endemic to Chile, and its distribution is restricted from Concepcion to ChiloeIsland. A survey conducted during January 2007, involving 26 fish from the Maullo´n River in Southern Chile, shows that infracommunities richness ranged from 0 to 5 with a mean species richness of 2.3 (SD ¼ 1.3).

Aquatic Living Resources, 2023 Anadromous European smelt (Osmerus eperlanus) is a keystone species in lake and river ecosystems. In the past and present, stock declines in several of its habitats have been reported. The reasons for this are unclear.

Journal of Fish Biology, 2005 Partitioned Bayesian analysis of whole mitochondrial genome sequences from 30 basal teleosts confidently placed Sundasalanx(Sundasalangidae) within the Clupeiformes, not Osmeriformes as originally thought. This study represents the first demonstration of the phylogenetic position of Sundasalanx on a phylogenetic tree.

Fisheries, Volume 48, Issue 7, Page 295-306, July 2023., 2023 Arctic freshwater ecosystems and fish populations are largely shaped by seasonal and long‐term watershed hydrology. In this paper, we hypothesize how changing air temperature and precipitation will alter freeze and thaw processes, hydrology, and instream habitat to assess potential indirect effects, such as the change to the foraging and behavioral ...

A preliminary study on the age and growth of the argentine, Argentina sphyraena (Actinopterygii: Osmeriformes: Argentinidae) from the eastern Adriatic Sea [PDF]
Acta Ichthyologica et Piscatoria, 2017 Background. Age determination is a basic step in understanding fish biology and dynamics of fish populations. The only available data on the age and growth of argentine, Argentina sphyraena Linnaeus, 1758, a non-commercially exploited species of the ...
