Abstract— Logical equivalence between the notions of homology and synapomorphy is reviewed supported. So‐called transformational embodies two distinct logical components, one related to comparisons among different organisms other restricted within same organism. The former essentially hierarchical in nature, thus being fact a less obvious form taxic homology. latter logically equivalent so‐called serial broad sense (including homonomy, mass or iterative homology). Of three tests proposed...
We provide a general compilation of the diversity and geographical distribution Amazonian fishes, updated to end 2018. Our database includes documented distributions 4214 species (both from surrounding basins), compiled published information plus original data ichthyological collections. results show that Amazon basin comprises most diverse regional assemblage freshwater fishes in world, with 2716 valid (1696 which are endemic) representing 529 genera, 60 families, 18 orders. These permit...
Abstract The upper rio Paraná basin drains the most developed and environmentally degraded region in South America: Brazilian southeast. While it is one of well-known Neotropical fish assemblages, also threatened by anthropic activity. Urbanization, deforestation, dam construction, invasive species, water pollution not only reduce living area species but alter our perception its biotic elements. Such changes are so profound pervasive that raise uncertainties about native or non-native status...
ABSTRACT Biogeography of Amazonian fishes (2,500 species in vastly disjunct lineages) is complex and has so far been approached only partially. Here, we tackle the problem on basis largest database yet geographical distribution phylogenetic relationships fishes, including all information available. Distributions 4,095 (both outgroups) 84 hypotheses (comprising 549 phylogenetically-informative nodes) were compiled, qualified plotted onto 46 areas (29 17 non-Amazonian). The was analyzed with...
ABSTRACT A new species of the Copionodontinae genus Copionodon is described from riacho do Mosquito, tributary to rio Santo Antônio, Paraguaçu basin in Diamantina Plateau, Bahia State, northeastern Brazil. This represents northernmost occurrence subfamily yet known and a relictual population, apparently restricted an underground sector stream its immediate downstream exit. The can be readily recognized by combination presence opercular odontodes, mostly uniform coloration body, lack free...
A new species of Cetopsis is described from Guiana Shield drainages in Guyana and Suriname. The found the Konawaruk River tributaries, Essequibo basin, Guyana, Mauritie Creek, tributary to Tempati River, upper Commewijne taxon can be distinguished all congeners by a combination features: dark spots on sides body eye-sized or larger, dark, bilobed patch at base caudal fin, absence humeral spot, pigmentation along fin-membrane posterior first dorsal-fin ray, dorsal extending ventrally bases...
Microcambeva bendego, a small psammophilous catfish species, is described from the rio Guapi-Macacu basin at Guanabara Bay in Rio de Janeiro State, an Atlantic Forest remnant. This coastal drainage has been explored by several naturalists and fish researchers since 19th century. It with remarkably high endemism species richness, some recently-described threatened species. The new distinguished all congeners two distinctive characters: long finger-like projections branchial isthmus large...
The Copionodontinae is described as a new subfamily of the neotropical catfish family Trichomycteridae. It comprises two genera and three species from north-eastern Brazil: Copionodon gen. nov. (including C. pecten sp. orthiocarinatus nov.) Glaphyropoma gen G. rodriguesi can be diagnosed externally by anterior position dorsal fin, presence well-developed adipose strongly spatulate shape jaw teeth. hypothesized monophyletic on basis several synapomorphies in internal external anatomy....
The trichomycterid catfish species Trichomycterus alternatus (Eigenmann, 1917) and zonatus 1918) are reportedly among the most pervasive in mid- to high-elevation coastal streams of Southeastern Brazil. Despite their apparent abundance ecological ubiquity, applicability names is still uncertain. Examination type material two reveals that part confusion stems from a mixing T. series. Other issues relate reports character conditions respective do not actually correspond situation specimens....
Abstract Freshwater ecosystems represent less than 0.01% of Earth's surface water but proportionately encompass the most species‐rich environment on planet, including nearly one‐third all vertebrate species. Even though inland continental waters are widely regarded as highly endangered ecosystems, their species assemblages mostly ignored in conservation plans, largely because spatial patterns freshwater remain poorly understood. This is particularly severe throughout Neotropics, notably...
The family Myrocongridae comprises some of the rarest and least known benthopelagic eel species. It is composed a single genus, Myroconger Günther, 1870, five valid species: M. compressus from Atlantic Ocean; gracilis Castle, 1991, prolixus Castle & Béarez, 1995, nigrodentatus Pacific seychellensis Karmovskaya, 2006, Indian Ocean. Herein, we report on an additional species Ocean, pietschi n. sp., based specimen obtained Aracati Bank, North Brazilian ridge, off Ceará State, western South...
ABSTRACT A new species of the copionodontine genus Copionodon is described from upper reaches a tributary to rio Paraguaçu in Diamantina Plateau, Bahia State, northeastern Brazil. This represents northernmost occurrence subfamily yet known. The can be readily recognized by its large eye without free orbital rim. Other characters such as entirely cartilaginous second hypobranchial, and uniformly broad irregular midlateral dark band further diagnose taxon. Its particular combination...
Abstract Quantitative traits are a source of evolutionary information often difficult to handle in cladistics. Tools exist analyse this kind data without subjective discretization, avoiding biases the delimitation categorical states. Nonetheless, our ability accurately infer relationships from continuous characters is incompletely understood, particularly under parsimony analysis. This study evaluates accuracy phylogenetic reconstructions simulated matrices evolving alternative processes and...
A recent review of the homology concept in cladistics is critiqued light historical literature. Homology as a notion relevant to recognition clades remains equivalent synapomorphy. Some symplesiomorphies are "homologies" inasmuch they represent synapomorphies more inclusive taxa; others complementary character states that do not imply any shared evolutionary history among taxa exhibit state. Undirected character-state change (as characters optimized on an unrooted tree) necessary but...
Abstract The catfish genus Trichomycterus is a recognized taxonomic bottleneck in Neotropical ichthyology. hitherto poorly-known diversity of the Rio Doce Basin, Brazil, here investigated using an iterative approach based on morphology and cytochrome oxidase subunit I (COI) sequence data. Specimens from entire Drainage adjacent basins are analysed, including type localities. Iteration different sources data, dense sampling representation, plus information relevant specimens allows clear view...
We report on the only known case of independent discovery unrooted trees in a historical science outside biological systematics. The method textual criticism (ecdotics, i.e., building text-version genealogies) created by French philologist Henri Quentin (1872–1935) proposes use type branching scheme equivalent to phylogenetics. Because Quentin's has never become prevailing paradigm philology, his insight into not been noticed previous studies comparing philology and In fact, modern is seen...
We present the taxonomic description of Tarumaniidae, a new family South American freshwater fishes including genus (Tarumania) and species (Tarumania walkerae) from Central Amazon. The taxon displays an extraordinary set unique characteristics, which sets it apart all other known bony fishes, either in America or elsewhere. Tarumaniidae has reverse-imbricated scales on head, 244 more along midlateral lateral series, 11-chambered swimbladder extending most body, anteriorly deflectable pelvic...
