Panaque (Panaque), with Descriptions of Three New Species from the Amazon Basin (Siluriformes, Loricariidae)
Copeia 2010, No. 4, 676–704 Revision of Panaque (Panaque), with Descriptions of Three New Species from the Amazon Basin (Siluriformes, Loricariidae) Nathan K. Lujan1, Max Hidalgo2, and Donald J. Stewart3 The Panaque nigrolineatus group (subgenus Panaque) is revised; three nominal species—P. cochliodon, P. nigrolineatus, and P. suttonorum—are redescribed and three new species are described. Panaque armbrusteri, new species, is widespread in the Tapajo´ s River and its tributaries in Brazil and is distinguished by having a supraoccipital hump, higher numbers of jaw teeth and an ontogenetic increase in interpremaxillary and intermandibular tooth-row angles, relatively short paired-fin spines, and dorsal margin of infraorbital six flared laterally. Panaque schaeferi, new species, is widespread in main-channel habitats of the upper Amazon (Solimo˜es) River basin in Brazil and Peru; it is distinguished by having a coloration consisting of dark or faded black spots evenly distributed on a pale gray to brown base, and by its large adult body size (.570 mm SL). Panaque titan, new species, is distributed in larger, lowland to piedmont rivers of the Napo River basin in Ecuador, and is distinguished by having a postorbital pterotic region bulged beyond the ventral pterotic margin, coloration consisting of irregular and widely spaced dark gray to brown stripes on light brown to tan base, and large adult body size (.390 mm SL). A relatively large pterotic, indicative of an enlarged gas bladder and gas bladder capsule, and allometric increases in tooth number are hypothesized to be synapomorphies uniting members of the subgenus Panaque.

Copyright 2013. 2 ABSTRACT This work is concerned with the historical progression, to fixation, of an allele in a finite population. This progression is characterised by the average frequency trajectory of alleles which achieve fixation before a given time, T . Under a diffusion analysis, the average trajectory, conditional on fixation by time T , is shown to be equivalent to the average trajectory in an unconditioned problem involving addi- tional selection. We call this additional selection ‘fictitious selection’; it plays the role of a selective force in the unconditioned problem but does not exist in reality. It is a consequence of conditioning on fixation. The fictitious selection is frequency dependent and can be very large compared with any real selection that is acting. We derive an approximation for the characteristic trajectory of a fixing allele, when subject to real additive selection, from an unconditioned problem where the total selection is a combination of real and fictitious selection. -
Variation and Genetic Structure of the Endangered Lepus Flavigularis (Lagomorpha: Leporidae)

Corrected 10-VII-2017. Accepted 09-VIII-2017. Abstract: Lepus flavigularis, is an endemic and endangered species, with only four populations inhabiting Oaxaca, México: Montecillo Santa Cruz, Aguachil, San Francisco del Mar Viejo and Santa María del Mar. Nevertheless, human activities like poaching and land use changes, and the low genetic diversity detected with mitochondrial DNA and allozymes in previous studies, have supported the urgent need of management strategies for this species, and suggest the definition of management units. For this, it is necessary to study the genetic structure with nuclear genes, due to their inheritance and high polymorphism, therefore, the objective of this study was to examine the variation and genetic structure of L. flavigularis using nuclear microsatellites. We sampled four populations of L. flavigularis and a total of 67 jackrabbits were captured by night sampling during the period of 2001 to 2006. We obtained the genomic DNA by the phenol-chloroform-isoamyl alcohol method. To obtain the diversity and genetic structure, seven microsatellites were amplified using the Polymerase Chain Reaction (PCR); the amplifications were visualized through electrophoresis with 10 % polyacrylamide gels, dyed with ethidium bromide. -
Definition and Estimation of Higher-Order Gene Fixation Indices
Copyright 0 1987 by the Genetics Society of America Definition and Estimation of Higher-Order Gene Fixation Indices Kermit Ritland Department of Botany, University of Toronto, Toronto, M5S IAl Canada Manuscript received March 26, 1987 Revised copy accepted August 15, 1987 ABSTRACT Fixation indices summarize the associations between genes that arise from the joint effects of inbreeding and selection. In this paper, fixation indices are derived for pairs, triplets and quadruplets of genes at a single multiallelic locus. The fixation indices are obtained by dividing cumulants by constants; the cumulants describe the statistical distribution of alleles and the constants are functions of gene frequency. The use of cumulants instead of moments is necessary only for four-gene indices, when the fourth cumulant is used. A second type of four-gene index is also required, and this index is based upon the covariation of second-order cumulants. At multiallelic loci, a large number of indices is possible. If alleles are selectively neutral, the number of indices is reduced and the relationship between gene identity and gene cumulants is shown.-Two-gene indices can always be estimated from genotypic frequency data at a single polymorphic locus. Three-gene indices are also estimable except when allele frequency equals one-half. Four-gene indices are not estimable unless selection is assumed to have an equal effect upon each allele (such as under selective neutrality) and the locus contains at least three alleles of unequal frequency. For diallelic or selected loci, an alternative four- gene fixation index is proposed. This index incorporates both types of four-gene associations but cannot be related to gene identity. -
Albino Common Plecostomus ( Hypostomus Plecostomus ) Sht
Albino Common Plecostomus ( Hypostomus plecostomus ) Order: Siluriformes - Family: Loricariidae - Subfamily: Also known as: Spotted Hypostomus Type: Tropical—Egg Layers Origin: Hypostomus punctatus is a freshwater fish native to South Amer- ica, in the coastal drainages of southeastern Brazil. Description: The Suckermouthed Catfish (Hypostomus punctatus) is a tropical fish known as a Plecostomus belonging to the armored sucker- mouth catfish family (Loricariidae). It is one of a number of species com- monly referred to as the Common Pleco by aquarists. Physical Characteristics: Suckermouthed catfish is a species of Lori- cariidae. Like other members of this family, it has a suckermouth, armor plates, strong dorsal and pectoral fin spines, and the omega iris. Hyposto- mus punctatus is difficult to distinguish from closely related species, such as Hypostomus plecostomus. Identification is relatively difficult as there are many different similar species labeled as Common Pleco. This species has a light brown coloration with a pattern of darker brown spots (the last part of its scientific name, punctatus, means "spotted"). Because of this, the species may also be known as the Spotted Hypostomus. There is no striping pattern. Also, they are lighter than H. plecostomus. Maximum Size:These fish grow to about 30 centimetres (12 in) 25cm. Color Form: Usually pale yellow in color. Sexual dimorphism: Lifespan: The Behavior: Habitat: It is found in the wild in fast-flowing rivers as well as in flooded areas. The Suckermouthed catfish is mainly herbivorous and feeds on algae, detritus as well as plants and roots Diet: Omnivore - A useful herbivore in an aquarium with algae, the Albino Common Pleco will keep algae under control under normal tank condi- tions. -

Freshwater Fishes of Argentina: Etymologies of Species Names Dedicated to Persons
Ichthyological Contributions of PecesCriollos 18: 1-18 (2011) 1 Freshwater fishes of Argentina: Etymologies of species names dedicated to persons. Stefan Koerber Friesenstr. 11, 45476 Muelheim, Germany, [email protected] Since the beginning of the binominal nomenclature authors dedicate names of new species described by them to persons they want to honour, mostly to the collectors or donators of the specimens the new species is based on, to colleagues, or, in fewer cases, to family members. This paper aims to provide a list of these names used for freshwater fishes from Argentina. All listed species have been reported from localities in Argentina, some regardless the fact that by our actual knowledge their distribution in this country might be doubtful. Years of birth and death could be taken mainly from obituaries, whereas those of living persons or publicly unknown ones are hard to find and missing in some accounts. Although the real existence of some persons from ancient Greek mythology might not be proven they have been included here, while the names of indigenous tribes and spirits are not. If a species name does not refer to a first family name, cross references are provided. Current systematical stati were taken from the online version of Catalog of Fishes.
