A new species of Pseudoniphargus (Crustacea, Amphipoda) from subterranean water of northeastern Morocco: Historical biogeography and evolutionary aspects Naturalis
Abiari, A. Fakher el; Oulbaz, Z.; Messouli, M.; Coineau, N..
A new species of Pseudoniphargus, P. longiflagellum (Crustacea, Amphipoda) is described from subterranean fresh water of the Riftan region of Morocco. This species is closely related to the group P. ruffoi-P. longipes, which shares several apomorphic characters. The two-step model of colonization and evolution provides an understanding of the origin and the age of this stygobiont. P. longiflagellum is derived from marine ancestors that lived in the coastal groundwater of the Tethyan South-Rifian channel during the Miocene Tortonian period. The regression of this corridor during the late Tortonian period or at the beginning of the Messinian period may have played a major role in the evolutionary history through vicariance.

Areas of endemism of hummingbirds (Aves: Apodiformes: Trochilidae) in the Andean and Neotropical regions Rev. Bras. Zool.
Ouvernay,Daiane; Ferreira,Ildemar; Morrone,Juan J..
ABSTRACT Using track analysis and cladistic biogeography, we identified areas of endemism of hummingbirds in the Andean and Neotropical regions. Our results point out that the current areas of endemism of hummingbirds occur in the Andes, Guiana Shield, the Lesser Antilles, western Central and North America and the Chiapas Highlands. The cladistic biogeographic analysis suggests a hummingbird distribution shaped mainly by dispersal events.

Detection of areas of endemism on two spatial scales using Parsimony Analysis of Endemicity (PAE): the Neotropical region and the Atlantic Forest Biota Neotropica
Sigrist,Mário Sérgio; Carvalho,Claudio José Barros de.
An important biological challenge today is the conservation of biodiversity. Biogeography, the study of the distribution patterns of organisms, is an important tool for this challenge. Endemism, the co-occurrence of several species unique to the same area, has important implications for the preservation of biodiversity, since many areas of endemism are also areas with large human impact. More rigorously defined, areas of endemism are historical units of distributional congruence of monophyletic taxa. These areas often assumed to be due to nonrandom historical events that favored conditions associated with high rates of speciation. Thus, understanding endemism and the delimitation of endemic areas has important implications for conservation. Today, most...

Direct analysis of vicariance in Neotropical mayflies (Ephemeroptera) Anais da ABC (AABC)
MOLINERI,CARLOS; NIETO,CAROLINA; DOMÍNGUEZ,EDUARDO.
Abstract: The distribution of aquatic insects has been poorly explored in quantitative analyses aiming at the historical reconstruction of area relationships in the Neotropics. Ephemeroptera is an ancient group, characterized by its low vagility, and of high richness and endemicity in this region. Systematic knowledge of the group has enormously increased in the last decades, achieving a sufficient background to explore biogeographical historical patterns. Our aim is to reconstruct area history in the Neotropics using the rationale of Barrier biogeography (Hovenkamp protocol). We present eleven mayfly phylogenies, representing groups that evolved independently at least from the Jurassic (i.e., not a one-taxon history). With these groups, we conducted...

Distributional patterns of Aptian-Albian paleoichthyofauna of Brazil and Africa based on Track Analysis Anais da ABC (AABC)
PARMÉRA,THAÍS C.C.; GALLO,VALÉRIA; SILVA,HILDA M.A. DA; FIGUEIREDO,FRANCISCO J. DE.
ABSTRACT The Aptian-Albian paleoichthyofauna in Brazil and Africa is quite diverse, yet their geographic patterns still require accounts. This work consists of a panbiogeographical analysis of paleoichthyofauna from Aptian-Albian through track analysis. Geographic coordinates were obtained and converted into paleocoordinates. Individual Tracks (ITs) and Generalized Tracks (GTs) were built with the aid of ArcView GIS v3.2 program using Trazos2004 extension. As a result, four GTs and tree Biogeographic Nodes (A, B and C) had been identified. GTs 1 and 2 shows two different faunas. GT3 indicates similarity between Brazil and Africa paleoichthyofauna suggesting the break-up of Gondwana as the event that separated it. GT4 represents a probable local seaway...

Distributions and phylogeographic data of rheophilic freshwater fishes provide evidences on the geographic extension of a central-brazilian amazonian palaeoplateau in the area of the present day Pantanal Wetland Neotropical Ichthyology
Ribeiro,Alexandre C.; Jacob,Rodrigo M.; Silva,Ronnayana R. S. R.; Lima,Flávio C. T.; Ferreira,Daniela C.; Ferreira,Katiane M.; Mariguela,Tatiane C.; Pereira,Luiz H. G.; Oliveira,Claudio.
The analysis of the distribution patterns presented by examples of freshwater fishes restricted to headwater habitat: the anostomid Leporinus octomaculatus, the characins Jubiaba acanthogaster, Oligosarcus perdido, Moenkhausia cosmops, Knodus chapadae, Planaltina sp., the loricariid Hypostomus cochliodon, and the auchenipterid Centromochlus sp. provided evidences of a relatively recent shared history between the highlands of the upper rio Paraguay and adjoining upland drainage basins. Restricted to headwater of the uplands in the upper rio Paraguay and adjoining basins, these species provide biological evidence of the former extension of the central Brazilian plateau before the origin of the Pantanal Wetland. Disjunction took place due to an ecological...

Does biogeography have a future in a globalized world with globalized faunas? Naturalis
Schram, F.R..
The study of biogeography was once a pillar of evolution science. Both Darwin and especially Wallace found great inspiration from the consideration of animal distributions. However, what is to happen to this discipline in a time of global trade, mass movement of people and goods, and the resulting globalization of the planet’s biota? Can we still hope to delve into the fine points of past geography as it affected animal and plant evolution? Maybe we can, but only with careful study of life forms that suffer minimal affects – at present – from globalization, viz., marginal faunas of quite inaccessible environments. Two examples taken from syncarid crustaceans illustrate this point. Bathynellacea provide insight into ancient patterns of distribution and...

Historical relationships among areas of endemism in the tropical South America using Brooks Parsimony Analysis (BPA) Biota Neotropica
Sigrist,Mário Sérgio; Carvalho,Claudio José Barros de.
Areas of endemism are the smallest units of biogeographical analysis. One of its definitions is that these areas harbor organisms with restricted distributions caused by non random historical factors. The aim of this study was to examine historical relationships among areas of endemism in the Neotropics using Brooks Parsimony Analysis (BPA). We applied BPA to 12 unrelated taxa distributed within two sets of endemic areas in order to: (1) compare the proposed endemic area classifications; (2) examine whether Amazonia and Atlantic Forest are true biogeographic units and, (3) examine whether the inclusion of open area formations influence area relationships of the surrounding forests. General area cladograms revealed a basal split between Amazonian and...

Phylogeography and evolutionary patterns in Sporothrix spanning more than 14 000 human and animal case reports Naturalis
Zhang, Y.; Hagen, F.; Stielow, B.; Rodrigues, A.M.; Samerpitak, K.; Zhou, X.; Feng, P.; Yang, L.; Chen, M.; Deng, S.; Li, S.; Liao, W.; Li, R.; Li, F.; Meis, J.F.; Guarro, J.; Teixeira, M.; Al-Zahrani, H.S.; Pires de Camargo, Z.; Zhang, L.; Hoog, G.S. de.
Pathology to vertebrate hosts has emerged repeatedly in the order Ophiostomatales. Occasional infections have been observed in Sporothrix mexicana at a low level of virulence, while the main pathogenic species cluster in a derived clade around S. schenckii s.str. In this paper, phylogeny and epidemiology of the members of this clade were investigated for 99 clinical and 36 environmental strains using four genetic loci, viz. rDNA ITS and partial CAL, TEF1, and TEF3; data are compared with amplified fragment length polymorphism (AFLP) genotyping. The four main species of the pathogenic clade were recognised. The species proved to show high degrees of endemicity, which enabled interpretation of literature data where live material or genetic information is...

Taxonomy, phylogeny, historical biogeography, and historical ecology of the genus Pontonia (Crustacea: Decapoda: Caridea: Palaemonidae) Naturalis
Fransen, C.H.J.M..
Species of the genus Pontonia Latreille, 1829, are distributed in tropical and subtropical waters around the world, living in association with either molluscan or ascidian hosts. In the present taxonomic revision, Pontonia sensu lato is divided into six genera: Pontonia sensu stricto; Ascidonia gen. nov., Rostronia gen. nov., Dactylonia gen. nov., Odontonia gen. nov., and Bruceonia gen. nov. A total of 29 species is described and figured, four of which are new to science: Pontonia pilosa spec. nov., Dactylonia holthuisi spec. nov., Odontonia rufopunctata spec. nov., and O. seychellensis spec. nov. The division in six genera is based on a stepwise phylogenetic analysis using morphological characters, performed using PAUP and McClade software. The...

The phylogeny of crested newts (Triturus cristatus superspecies): nuclear and mitochondrial genetic characters suggest a hard polytomy, in line with the paleogeography of the centre of origin Naturalis
Arntzen, J.W.; Themudo, G. Espregueira; Wielstra, B..
Newts of the genus Triturus (Amphibia, Caudata, Salamandridae) are distributed across Europe and adjacent Asia. In spite of its prominence as a model system for evolutionary research, the phylogeny of Triturus has remained incompletely solved. Our aim was to rectify this situation, to which we employed nuclear encoded proteins (40 loci) and mitochondrial DNA-sequence data (mtDNA, 642 bp of the ND4 gene). We sampled up to four populations per species covering large parts of their ranges. Allozyme and mtDNA data were analyzed separately with parsimony, distance, likelihood and Bayesian methods of phylogenetic inference. Existing knowledge on taxonomic relationships was confirmed, including the monophyly of the genus and the groups of crested newts (four...

Un nouveau Microcharon (Isopoda, Janiroidea) du Maroc — origine et biogéographie historique Naturalis
Boulanouar, M.; Yacoubi, M.; Messouli, M.; Coineau, N..
The interstitial crustacean isopods of the genus Microcharon (Microparasellidae) are relatively well-diversified and widely distributed in Morocco. A new species, M. boutini, is described. The 5-dentate mandibular pars incisiva, the elongated inner lobe of the exopodite, and the reduced armature of the first male pleopod characterize the species. M. boutini n. sp. belongs to the monophyletic messoulii group of species, the most primitive representatives of the genus. The distribution of M. boutini n. sp. covers both the northwestern part of the Jbilet and the nearest adjacent plain, as well as the High Atlas of the Marrakech piedmont. From a historical biogeographic point of view, interstitial ancestral marine populations would have been left in...

Zoogeography of Elasmobranchs in the Colombian Pacific Ocean and Caribbean Sea Neotropical Ichthyology
Navia,Andrés Felipe; Mejía-Falla,Paola Andrea; Hleap,José Sergio.
ABSTRACT In order to investigate zoogeographical patterns of the marine elasmobranch species of Colombia, species richness of the Pacific and Caribbean and their subareas (Coastal Pacific, Oceanic Pacific, Coastal Caribbean, Oceanic Caribbean) was analyzed. The areas shared 10 families, 10 genera and 16 species of sharks, and eight families, three genera and four species of batoids. Carcharhinidae had the highest contribution to shark richness, whereas Rajidae and Urotrygonidae had the greatest contribution to batoid richness in the Caribbean and Pacific, respectively. Most elasmobranchs were associated with benthic and coastal habitats. The similarity analysis allowed the identification of five groups of families, which characterize the elasmobranch...
