Fishing for the Secrets of Vertebrate Evolution in Threespine Sticklebacks DEVELOPMENTAL DYNAMICS 234:815–823, 2005 REVIEWS—A PEER REVIEWED FORUM Fishing for the Secrets of Vertebrate Evolution in Threespine Sticklebacks Catherine L. Peichel* The threespine stickleback (Gasterosteus aculeatus) is rapidly emerging as a new model genetic system to study questions at the interface of evolution and development. The relatively rapid and recent diversification of this small teleost fish, combined with the development of genetic and genomic tools for this fish, provides an unprecedented opportunity to identify the genetic and molecular basis of morphological variation in natural populations of vertebrates. Recently, the genes underlying two different adaptive morphological traits in stickleback have been identified. This work has provided answers to four longstanding questions in the field of evolution and development: (1) How many genes underlie morphological variation in natural populations? (2) What are the genes that underlie morphological variation in natural populations? (3) Do coding or regulatory mutations underlie morphological evolution? (4) What is the molecular and genetic basis of parallel morphological evolution? Because stickleback populations also display natural variation in morphology, life history, physiology, and behavior, extending the approaches used to identify the genetic basis of morphological variation in sticklebacks to other phenotypes is sure to yield further important insights into the genetic and developmental basis of diversity in natural populations.

The fish genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, and Schizothorax are examples of these groups among vertebrates, and the genera Magnibursatus (Trematoda), Margaritifera, Potomida, Microcondylaea, Leguminaia, Unio (Mollusca), and Phagocata (Planaria), among invertebrates. There is reason to believe that their ancestors spread to Europe through the Paratethys (or the proto-Paratethys basin that preceded it), where intense speciation took place and new genera of aquatic organisms arose.

Glacial lakes (lakes formed by glacial activity) are a common feature on the midwestern landscape. From small, productive potholes to the large windswept walleye “factories”, glacial lakes are an integral part of the communities within which they are found and taken collectively are a resource of national importance. Despite this value, lakes are commonly treated more as a commodity rather than a natural resource susceptible to degradation. Often viewed apart from the landscape within which they occupy, human activities on land—and in water—have compromised many of these systems.

PHENOTYPIC COVARIATION WITH CLOSELY RELATED SPECIES 0. M. BLOUW* AND 0. W. HAGEN Department of Biology, University of New Brunswick, Fredericton, New Brunswick, Canada E3B6EI Received2.xii.83 SUMMARY The fourspine stickleback (Apeltes quadracus) and ninespine stickleback (Pungitiuspungitius)have similar ecologies, they often coexist, and they share parallel polymorphisms for the number of dorsal spines. Spine number is posi- tively correlated between them for 86 sites in eastern Canada. Dorsal spine length is positively correlated with spine number within each species, and spine length is positively correlated between them. Spine length for both species is also positively correlated with the presence of predatory fishes and negatively corre- lated with vegetation cover. Finally, spine number for both Apeltes and Pungirius is lower where they coexist with a new species of stickleback (Gasterosteus sp.) which is found only in environments where predation risk is low. These patterns of covariation within and between species are evidence for natural selection, and they suggest that predators are a selective agent favouring the higher-spined morphs. We discuss these results with respect to the idea that geographic variation in Pun gidus reflects historical processes of isolation and differentiation during the Pleistocene era. 1. INTRODUCTION A powerful method for detecting the action of natural selection is to search for covariation among homologous polymorphic traits in closely related and ecologically similar species where they coexist (Clarke, 1975; Koehn and Mitton, 1972; Turner 1977).

Nelson3 1 Institute of Parasitology, Biology Centre of the Czech Academy of Sciences, České Budějovice, Czech Republic; 2 Division of Natural Sciences, St. Norbert College, De Pere, Wisconsin, USA; 3 North/South Consultants Inc., Winnipeg, Canada Abstract: A survey of the species of the Proteocephalus-aggregate from sticklebacks (Actinopterygii: Gasterosteidae) is provided. The occurrence of three species in North America is confirmed: (i)Proteocephalus filicollis(Rudolphi, 1802), which has been reported from the three-spined stickleback, Gasterosteus aculeatus Linnaeus, in the northeastern part of North America (Newfoundland); (ii) Proteocephalus pugetensis Hoff et Hoff, 1929 occurs also in G. aculeatus, but in northwestern North America (British Columbia and Washington); and (iii) Proteocephalus culaeae sp. n., which is described from the brook stickleback, Culaea inconstans (Kirtland), in Manitoba (Canada). Another species, Proteocephalus ambiguus (Dujardin, 1845), a specific parasite of the nine-spined stickleback, Pungitius pungitius (Linnaeus), and type species of the genus, has also been found in North America (Alberta, Canada), but its vouch- ers are in poor condition and cannot be reliable assigned to this species. Both species reported from three-spined stickleback differ from each other by the shape of the scolex (rounded in P. filicollis versus continuously tapered towards the anterior extremity in P. pugeten- sis) and the apical sucker (widely oval to subspherical in frontal view in P.

Meyer: Helminths of Fishes from Trumbull Lake, Clay County, Iowa Helminths of Fishes from Trumbull Lake, Clay County, Iowa 1 By FRED PAUL MEYER INTRODUCTION In 1953 it was observed that the fishes taken by anglers in Trum­ bull Lake, Clay County, Iowa, were "grubby" or wormy" and hence considered unfit for human consumption. This study was undertaken to ascertain in greater detail the parasite fauna of that area. Work was begun in the summer of 19 54 and collections were made inter­ mittently through the summers of 1954 and 1955. All fish were ex­ amined at the Iowa Lakeside Laboratory, Lake Okoboji, Iowa. Final identifications of the parasites were completed at Iowa State College during 1956 and 1957.
