The Freshwater Herring of Lake Tanganyika Are the Product of a Marine Invasion Into West Africa

Wilson1,2¤*, Guy G. Teugels3, Axel Meyer1 1 Department of Biology, University of Konstanz, Konstanz, Germany, 2 Zoological Museum, University of Zurich, Zurich, Switzerland, 3 Ichthyology Laboratory, Royal Museum for Central Africa, Tervuren, Belgium Abstract The spectacular marine-like diversity of the endemic fauna of Lake Tanganyika, the oldest of the African Great Lakes, led early researchers to suggest that the lake must have once been connected to the ocean. Recent geophysical reconstructions clearly indicate that Lake Tanganyika formed by rifting in the African subcontinent and was never directly linked to the sea. Although the Lake has a high proportion of specialized endemics, the absence of close relatives outside Tanganyika has complicated phylogeographic reconstructions of the timing of lake colonization and intralacustrine diversification. The freshwater herring of Lake Tanganyika are members of a large group of pellonuline herring found in western and southern Africa, offering one of the best opportunities to trace the evolutionary history of members of Tanganyika’s biota. Molecular phylogenetic reconstructions indicate that herring colonized West Africa 25–50MYA, at the end of a major marine incursion in the region. Pellonuline herring subsequently experienced an evolutionary radiation in West Africa, spreading across the continent and reaching East Africa’s Lake Tanganyika during its early formation. While Lake Tanganyika has never been directly connected with the sea, the endemic freshwater herring of the lake are the descendents of an ancient marine incursion, a scenario which may also explain the origin of other Tanganyikan endemics. -

Argulus Ambystoma, a New Species Parasitic on the Salamander Ambystoma Dumerilii from Mexico (Crustacea: Branchiura: Argulidae)1
Argulus ambystoma, a New Species Parasitic on the Salamander Ambystoma dumerilii from Mexico (Crustacea: Branchiura: Argulidae)1 WILLIAM J. POLY2, Department of Zoology, Southern Illinois University, Carbondale, IL 62901-6501 ABSTRACT. A new species of Argulus is described based on 18 specimens taken from the salamander ("achoque" or "ajolote") Ambystoma dumerilii Duges, collected in Lake Patzcuaro, Michoacan, Mexico. Diagnostic characters include the shape of the respiratory areas, number of sclerites in suction cup rods, and structures on the legs of males. Females are heavily stippled, whereas males have a very distinctive pigment pattern consisting of abundant melanophores covering the testes dors ally and two dark, inverted triangular patches on the carapace dorsally. The new species is similar to the North American species, A versicolor,A. americanus, A. maculosus, and A diversus. A single, dorsal pore was observed on each caudal ramus using scanning electron microscopy; these pores have not been reported previously in the Branchiura.

Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described.

ABSTRACT Anchoviella Vaillanti
Volume 45(esp.):33‑40, 2014 REDESCRIPTION OF THE FRESHWATER ANCHOVY ANCHOVIELLA VAILLANTI (STEINDACHNER, 1908) (CLUPEIFORMES: ENGRAULIDAE) WITH NOTES ON THE DISTRIBUTION OF ESTUARINE CONGENERS IN THE RIO SÃO FRANCISCO BASIN, BRAZIL 1,2 MARINA VIANNA LOEB 1,3 JOSÉ LIMA DE FIGUEIREDO ABSTRACT Anchoviella vaillanti (Steindachner, 1908) was described based on few specimens from the middle Rio São Francisco; however, several specimens of the species have been collected in recent decades. The range of morphological variation of A. vaillanti could thus be reassessed based on a larger number of specimens currently available in fish collections, and the species redescribed. Anchoviella vaillanti can be recognized among freshwater congeners by the relative position of the pelvic, dorsal and anal fins. Records of the species in ichthyological collections are restricted to the upper and middle portions of the Rio São Francisco basin, but the species might also occur in the lower Rio São Francisco. Comments on the distribution of the marine species of Anchoviella from the lower Rio São Francisco basin and an identification key including those species and A. vaillanti are provided.

Ambush Predator’ Guild – Are There Developmental Rules Underlying Body Shape Evolution in Ray-Finned Fishes? Erin E Maxwell1* and Laura AB Wilson2
Maxwell and Wilson BMC Evolutionary Biology 2013, 13:265 http://www.biomedcentral.com/1471-2148/13/265 RESEARCH ARTICLE Open Access Regionalization of the axial skeleton in the ‘ambush predator’ guild – are there developmental rules underlying body shape evolution in ray-finned fishes? Erin E Maxwell1* and Laura AB Wilson2 Abstract Background: A long, slender body plan characterized by an elongate antorbital region and posterior displacement of the unpaired fins has evolved multiple times within ray-finned fishes, and is associated with ambush predation. The axial skeleton of ray-finned fishes is divided into abdominal and caudal regions, considered to be evolutionary modules. In this study, we test whether the convergent evolution of the ambush predator body plan is associated with predictable, regional changes in the axial skeleton, specifically whether the abdominal region is preferentially lengthened relative to the caudal region through the addition of vertebrae. We test this hypothesis in seven clades showing convergent evolution of this body plan, examining abdominal and caudal vertebral counts in over 300 living and fossil species. In four of these clades, we also examined the relationship between the fineness ratio and vertebral regionalization using phylogenetic independent contrasts. Results: We report that in five of the clades surveyed, Lepisosteidae, Esocidae, Belonidae, Sphyraenidae and Fistulariidae, vertebrae are added preferentially to the abdominal region. In Lepisosteidae, Esocidae, and Belonidae, increasing abdominal vertebral count was also significantly related to increasing fineness ratio, a measure of elongation. Two clades did not preferentially add abdominal vertebrae: Saurichthyidae and Aulostomidae. Both of these groups show the development of a novel caudal region anterior to the insertion of the anal fin, morphologically differentiated from more posterior caudal vertebrae. -

Final EIS, Donlin Gold Project
Donlin Gold Project Chapter 3: Environmental Analysis Final Environmental Impact Statement 3.13 Fish and Aquatic Resources 3.13 FISH AND AQUATIC RESOURCES SYNOPSIS This section describes conditions and evaluates potential impacts to fish and aquatic resources from the proposed action and alternatives. Each alternative is examined by major project component (Mine Site; Transportation Corridor; and Pipeline) by project phase (Construction, Operations, and Closure). An Essential Fish Habitat (EFH) Assessment is provided in Appendix Q. EXISTING CONDITION SUMMARY Fish and aquatic resources are of central importance to the livelihood of residents of the proposed project area. While other chapter sections (Section 3.5, Surface Water Hydrology, Section 3.7, Water Quality, and Section 3.21, Subsistence) discuss topics associated with fish and aquatic resources, this section characterizes aquatic habitat and the diversity, abundance, and distribution of fish in the Kuskokwim River and the drainages affected by the proposed project. The section also describes the regulatory framework associated with the management and protection of area fisheries and aquatic habitats and presents an analysis of expected consequences of the proposed project and alternatives. Both federal and state laws protect fish and aquatic resources that would be affected by components of the proposed project. Key laws and regulations include: the Clean Water Act (CWA), including Sections 402 and 404, which govern discharges to waters of the U.S.; the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson- Stevens Act), which governs protection of EFH; and state regulation of mining and water use and discharge permits as well as fish habitat protection requirements. The Kuskokwim River and many of its tributaries, including tributaries in the Crooked Creek drainage, are designated as EFH for Pacific salmon. -

They are involved in economic activities and represent an important part of a country’s raw material potential. Many other organisms are also subject to rational use and protection. They can be associated with true resource species through interspecifi c relationships. The Caspian and Aral Seas are continental water bodies, giant saline lakes. Both categories of species are represented in the benthic and pelagic communities of the Caspian and Aral Seas and are involved in human economic activities.
