Significance The formation of the Isthmus Panama, which linked North and South America, is key to understanding biodiversity, oceanography, atmosphere, climate in region. Despite its importance across multiple disciplines, timing emergence biological patterns it created have been controversial. Here, we analyze molecular fossil data, including terrestrial marine organisms, show that biotic migrations Panama began several million years earlier than commonly assumed. An evolution has broad...
Abstract The 27 extant species of sturgeons and paddlefishes (Order Acipenseriformes) represent a unique relict lineage fishes. Producers coveted black caviar, are one the most valuable wildlife commodities on earth. group is among endangered fishes with all listed under Convention International Trade in Endangered Species (CITES) Appendix I (two species) or II (25 species), only two considered Lower Risk by IUCN, four nine US taxa Caspian protected Act, local extinctions recorded for 19...

The represents first cave-adapted known Western Hemisphere one only 13 stygobitic gobiiforms worldwide, with all others limited distribution to Indo-Pacific region. taxon third independent evolution hypogean lifestyle sleepers, being two Oxyeleotris (O. caeca O. colasi)...
The Halieutichthys aculeatus species complex is reviewed. Members of this clade are distinguished by the presence tubercles on tail and a reticulate dorsal pigmentation pattern. Three recognized, including two new to science. A neotype chosen for H. aculeatus. bispinosus n. sp. characterized having relatively strong surface, row almost always present orbit, both sphenotic well developed sharp, trifid principal disk margin with anterior spinelet enlarged, dense arrangement comparatively large...
An improved and expanded nomenclature for genetic sequences is introduced that corresponds with a ranking of the reliability taxonomic identification source specimens. This an advancement "Genetypes" naming system, which some have been reluctant to adopt because use "type" suffix in terminology. In new nomenclature, are labeled "genseq," followed by (e.g., 1 if sequence from primary type), name genes were derived genseq-1 16S, COI). The numbered provides indication likely voucher. Included...
Systematic relationships within the Cirrhitoidei, a suborder of five closely related families, have been uncertain for over century. This is particularly true in reference to families Cheilodactylidae and Latridae, which revised numerous times past several decades. Species that included these two are found temperate regions around world, has led regionally-focused studies only exacerbated taxonomic confusion. Here we examine systematic Latridae using ultraconserved genomic elements with near...
A voucher is a permanently preserved specimen that maintained in an accessible collection. In genomics, vouchers serve as the physical evidence for taxonomic identification of genome assemblies. Unfortunately, vast majority vertebrate genomes stored GenBank database do not refer to specimens. Here, we urge researchers generating new assemblies deposit specimens accessible, permanent research collections, and link these publications, public databases, repositories. We also encourage...
Natural history museums are vital repositories of specimens, samples and data that inform about the natural world; this Formal Comment revisits a Perspective advocated for adoption compassionate collection practices, querying whether it will ever be possible to completely do away with whole animal specimen collection.
We examined global records of accessible natural history voucher collections (with publicly available data and reliable locality data) for terrestrial freshwater vascular plants, fungi, fishes, birds, mammals, herpetofauna (amphibians reptiles) highlight areas the world that would be considered undersampled sometimes called 'unexplored' (i.e., have relatively low, or no evidence of, past sampling efforts) under typical Western-scientific descriptions. also question what may mean in these...
Abstract Despite recent progress on the higher‐level relationships of Cichlidae and its Indian, Malagasy, Greater Antillean components, conflict uncertainty remain within species‐rich African, South American, Middle American assemblages. Herein, we combine morphological nucleotide characters from mitochondrial large ribosomal subunit, cytochrome c oxidase subunit I, NADH dehydrogenase four, b genes nuclear histone H3, recombination activating gene two, Tmo‐4C4, Tmo‐M27, S7 loci to analyse...
Although attempts to understand Central American freshwater fish provincialism date the 1960s, early efforts lacked wealth of distributional data now available. Biogeographic work on fishes has been largely descriptive and regional, a broader synthesis. Here we use parsimony analysis endemicity (PAE) elucidate faunistic relationships between major drainages delineate areas endemism. We then perform Brooks (BPA) resulting areas. The PAE recovered primary division four Pacific six Atlantic...
Ostariophysi is a superorder of bony fishes including more than 10,300 species in 1100 genera and 70 families. This traditionally divided into five major groups (orders): Gonorynchiformes (milkfishes sandfishes), Cypriniformes (carps minnows), Characiformes (tetras their allies), Siluriformes (catfishes), Gymnotiformes (electric knifefishes). Unambiguous resolution the relationships among these lineages remains elusive, with previous molecular morphological analyses failing to produce...
The contrasting distribution of species diversity across the major lineages cichlids makes them an ideal group for investigating macroevolutionary processes. In this study, we investigate whether different rates diversification may explain disparity in richness cichlid globally. We present most taxonomically robust time-calibrated hypothesis evolutionary relationships to date. then utilize temporal framework both species-rich and depauperate are associated with rapid shifts if exceptional...
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed the Code has already been discussed Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; 2009a-b; Dubois Gentile Snell Minelli Cianferoni Bartolozzi 2016; Amorim et al. 2016). This was again raised a letter supported 35 signatories published journal Nature (Pape 2016) on 15 September 2016. On 25 2016,...
Resolving patterns of ancient and rapid diversifications is one the most challenging tasks in evolutionary biology. These difficulties arise from confusing phylogenetic signals that are associated with interplay incomplete lineage sorting (ILS) homoplasy. Phylogenomic analyses hundreds, or even thousands, loci offer potential to resolve such contentious relationships. Yet, how much useful information these large data sets contain remains uncertain often goes untested. Here, we assess utility...
Little is known about the current state of freshwater biodiversity in Canada, one countries with greatest amount surface waters world. To address this knowledge gap, we compiled a list all available assessments conservation status for species (over 3000 taxa) and further evaluated overall six distinct taxonomic groups, focusing on organisms reliant fresh (i.e., aquatic plants, invertebrates (with focus mussels), fishes, herpetofauna (reptiles amphibians), birds, mammals). Overall, 11.7%...
In order to better integrate molecular phylogenetics and taxonomy, genetic sequences from type materials should be explicitly identified in publications using a consistent nomenclature. Despite relatively frequent sampling of types (particularly topotypes—samples the locality), practice noting that these were sampled is uncommon. Because lack an explicit nomenclature tied existence “type sequences” obscured. Also hindering progress taxonomy increasingly uncommon reporting locality voucher...
<i>Ichthyology & Herpetology</i> (formerly <i>Copeia</i>) publishes work on the biology of fishes, amphibians, and reptiles, or using those organisms as models for testing hypotheses broad significance.
Troglobitic cavefishes of the genus Typhleotris, endemic to coastal southwestern Madagascar, are taxonomically reviewed and a new darkly pigmented species, Typhleotris mararybe, is described from an isolated karst sinkhole on plain below Mahafaly Plateau. The known only Grotte de Vitane (Vitany) near town Itampolo, unique among blind in being uniformly pigmented, rather than fully depigmented or exceptionally light coloration. In addition its dark coloration (vs. depigmented, translucent...
We show using the most complete phylogeny of one species-rich orders vertebrates (Gobiiformes), and calibrations from rich fossil record teleost fishes, that genus Typhleotris, endemic to subterranean karst habitats in southwestern Madagascar, is sister group Milyeringa, similar systems northwestern Australia. Both groups are eyeless, our phylogenetic biogeographic results these obligate cave fishes now found on opposite ends Indian Ocean (separated by nearly 7,000 km) each others closest...
Abstract Convergent evolution is widely viewed as strong evidence for the influence of natural selection on origin phenotypic design. However, emerging evo‐devo synthesis has highlighted other processes that may bias and direct in presence environmental genetic variation. Developmental biases production variation channel convergent forms by limiting range phenotypes produced during ontogeny. Here, we study convergence brachycephalic dolichocephalic skull shapes among 133 species Neotropical...
