The new species is distinguished from congeners by the following characters: the odontodes embedded in thick integument that covers interopercle, the premaxillary bone smaller than maxilla, the presence of sesamoid supraorbital with lateral process, the supraorbital sensory pore s3 present, the discontinuous supraorbital sensory canal, 2–3 premaxillary tooth rows, the uniformly dark pigmentation on the trunk, 15 precaudal vertebrae, the skin of trunk with minute thread-like papillae, 7–8 pectoral-fin rays, 9–12 dorsal procurrent caudal-fin rays, 10–11 ventral procurrent caudal-fin rays, the distally unbranched barbels, the wider interorbital distance, 16 pairs of ribs, the first dorsal-fin pterygiophore inserting on vertebra 18, and the first anal-fin pterygiophore inserting on vertebra 21. It closely resembles T. alterus, T. belensis, T. boylei, and T. ramosus from the Puna region. Trichomycterus belensis and T. catamarcensis are recorded from new localities over 3,400 m elevation.","PeriodicalId":29892,"journal":{"name":"Ichthyology and Herpetology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136254998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forester","doi":"10.1643/h2022084","DOIUrl":"https://doi.org/10.1643/h2022084","url":null,"abstract":"Morphological variation is often maintained by complex and interrelated factors, complicating the identification of underlying drivers. Tadpole oral morphology is one such trait that may be driven by the independent and interacting effects of the environment and variation in developmental processes. Although many studies have investigated tadpole oral morphological diversity among species, few have sought to understand the drivers that underlie intraspecific variation. In this study, we investigated potential drivers of labial tooth number variation among populations of two species of tailed frogs, the Rocky Mountain Tailed Frog (Ascaphus montanus) and the Coastal Tailed Frog (A. truei). We counted labial teeth from 240 tadpoles collected across elevation (both species) and latitudinal (A. truei) gradients, providing a natural temperature gradient. We tested the effects of developmental stage and local temperature conditions on labial tooth number. We found that labial tooth number variation was independently affected by both developmental stage and local temperature, as well as the interacting effects of these two variables (pseudo-R2 5 67–77%). Our results also uncovered consistent patterns in labial tooth row formula across the ranges of both species; however, tadpoles of A. truei from northern British Columbia had a unique bifurcation of a posterior tooth row. This study highlights the diversity in intraspecific tadpole oral morphology and the interacting processes that drive it.","PeriodicalId":29892,"journal":{"name":"Ichthyology and Herpetology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135477369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides its unique color pattern, characterized by two conspicuous midlateral stripes, the new genus is differentiated from the remaining characid genera by the dentary tooth row, implanted internally, and by the presence of a pseudotympanum crossed by a bundle of epaxialis musculature at its dorsal portion, dividing the pseudotympanum into two muscle hiatuses.

{"title":"Demographics, Reproductive Characteristics, and Genetic Connectivity of Blue Suckers (Cycleptus elongatus) in a Large Tributary","authors":"Dakota S. Radford, Anthony P. Porreca, Cassi J. Moody-Carpenter, Kathryn A. Muller, Devon B. Keeney, Robert E. Colombo","doi":"10.1643/i2022042","DOIUrl":"https://doi.org/10.1643/i2022042","url":null,"abstract":"Widespread losses in river connectivity and habitat degradation have led to rapid declines in migratory freshwater fishes. Large, connected tributary systems are likely critical to the conservation of fluvial species when they provide access to life-cycle-dependent habitats. The Blue Sucker (Cycleptus elongatus) is a large-bodied migratory catostomid, endemic to the large rivers of North America and declining in abundance across much of its range. Blue Suckers occupying the Wabash River (Illinois/Indiana, USA), a large tributary within the Mississippi River basin, may be one of few remaining robust populations of this species. To understand the characteristics of a successful Blue Sucker population, we analyzed data from ten years of electrofishing surveys conducted in the lower Wabash River (2010–2019, n = 563 Blue Suckers). We found Blue Sucker presence probability increased at sites with snags and with increasing surface water velocity. The length–weight regression was comparable to other populations, and the mean relative weight was 94.27. Maturation was estimated to occur at a minimum of 422 mm total length, around 2–3 years of age. We found support for variable individual spawning preparedness evidenced by inconsistent gonadal development among pre-winter adults and found support for intermittent reproductive success evidenced by a multi-modal population age structure. Genetic analysis supported the presence of a panmictic population throughout the Wabash River system, with no barrier to separate this population from the greater Mississippi River basin metapopulation. The effective population size was estimated to be 632.8 (95% CI = 318.4–4,492.2), indicating the population is not at immediate risk of inbreeding depression but should continue to be monitored. The characteristics of this resilient lower Wabash River Blue Sucker population can inform the management and conservation of this imperiled species throughout its range.","PeriodicalId":29892,"journal":{"name":"Ichthyology and Herpetology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134884034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four species of Paracheilinus are reported from Australian waters: P. amanda, new species, from Flora, Holmes, and Osprey Reefs, Coral Sea, off northeast Queensland, and Harrier Reef, Great Barrier Reef; P. filamentosus from Lizard Island, Great Barrier Reef; P. flavianalis from Evans and Flinders Shoals, Timor Sea, off northeast Darwin, Northern Territory, and Ashmore, Scott, Seringapatam, and Hibernia Reefs in the north-western shelf of Western Australia; and P. nursalim from Flinders Shoal, Timor Sea, off northern Darwin, Northern Territory. Paracheilinus amanda, new species, has previously been confused for P. rubricaudalis from Melanesia, but molecular analysis of mitochondrial COI recovers both species as reciprocally monophyletic lineages, differing from each other by 1–1.2% in genetic distance. They further differ in aspects of live coloration of terminal phase (TP) males. Both species are allopatric and do not overlap in distribution. The new species is described on the basis of six specimens: the holotype and two paratypes from Harrier Reef, Great Barrier Reef, one paratype from Flora Reef, Coral Sea, and from two paratypes collected off Hula in southern Papua New Guinea, along the north-western margin of the Coral Sea. The discovery of P. nursalim in Australia represents a new and significant range extension from previous locality records of West Papua and Ambon Bay. Paracheilinus is rediagnosed, and keys, diagnoses, photographs, and Australian distribution records are presented for all species herein.","PeriodicalId":29892,"journal":{"name":"Ichthyology and Herpetology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134914043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

THOMSON, Professor Emeritus of the University of Arizona, enjoyed saying he was a marine scientist and ichthyologist in the Sonoran Desert. Those dissonant images invariably opened conversations revealing Don’s passion for marine science and his research program of over 40 years in the Gulf of California (Sea of Cortez). Don produced major contributions to knowledge about the ecology and ichthyofauna of the Gulf. He published more than 37 scientific papers and book chapters, but many who travel to the Gulf know of him primarily from the Tide Calendar of the Northern Gulf of California, which he produced annually from 1967 to 1994 (later produced by CEDO, the Centro Intercultural de Estudios de Desiertos y Océanos), or by his two books on the fishes of Gulf of California. His Reef Fishes of the Sea of Cortez, published in 1979 by John Wiley and Sons with Lloyd Findley and Alex Kerstitch (revised and republished by the University of Texas Press in 2000), remains the definitive reference on rocky-bottom fishes in the Sea of Cortez. It was preceded by the Gulf of California Fishwatcher’s Guide, with Nonie McKibbin (1976, 1978), a modest 79-page paperback with precise line drawings beautifully illustrated by Jenean Thomson, his wife. This first-ever field guide to Gulf fishes was self-published by Golden Puffer Press, sold out of his home, and marketed mostly by word-of-mouth; it nevertheless gained wide popularity and went through several printings. Its 209 species included the fishes most likely to be encountered by fishers and divers on near-shore rocky and sandy bottoms and in the tide pools of the northern Gulf. The Guide was significant in its time because it facilitated research and detailed observation of fishes and encouraged conversation among students, sport divers, and fishermen. Likely tattered, it can still be found in many personal libraries, having earned its place there as a repository of treasured memories. In addition to Don’s two books on Sea of Cortez fishes, his research papers ranged from: faunal biodiversity studies (e.g., Brusca and Thomson, 1977, the first faunal inventory of the Pulmo Reefs); predator–prey studies (e.g., Dungan et al., 1982); environmental impacts (e.g., Thomson et al., 1969; Robinson and Thomson, 1992); fish ecology (e.g., Thomson and Lehner, 1976; Thomson and Gilligan, 1983, 2002; Kotrschal and Thomson, 1986); fish taxonomy (e.g., Thomson and Eger, 1966; Moffat and Thomson, 1975); and behavioral biology of spawning in the Gulf Grunion, Leuresthes sardina (e.g., Reynolds and Thomson, 1974, 1979; Reynolds et al., 1976; Thomson and Muench, 1976). This scholarship grew from research based on extensive field work to investigate and document the ecology and biodiversity of fishes in an area poorly known and sparsely represented in natural history collections. As curator of the University of Arizona Fish Collection, he greatly expanded its holdings during his tenure. In 2021, the collection included mo","PeriodicalId":29892,"journal":{"name":"Ichthyology and Herpetology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43928525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Joshua M. Kapfer and Donald J. Brown (Eds.). 2022. University of Wisconsin Press. ISBN 9780299335205. xxi þ 1175 p. $74.95 (hardcover).—When Amphibians and Reptiles of Wisconsin arrived, I was surprised by the weight of the box. Upon opening the box, I was looking at the largest single-volume state guide to amphibians and reptiles ever produced. The only larger guide is the three-volume Ohio series (Pfingsten et al., 2013; Davis et al., 2021). This is the first major work on Wisconsin’s herpetofauna since Natural History of the Amphibians and Reptiles of Wisconsin (Vogt, 1981), and it exceeds the length of that book by more than 900 pages! None of the guides to adjoining states, including Minnesota (Moriarty and Hall, 2014), Illinois (Phillips et al., 2022), Iowa (LeClere, 2013), or Michigan (Holman, 2012), comes close to the breadth and depth of herpetological information covered in this book. Wisconsin is in the Midwest portion of the United States in the Great Lakes region and near the Canadian border. This latitude, and the corresponding climate (long, cold winters), partially explain the relatively low amphibian and reptile diversity (54 species) relative to southern states, where the herpetological species richness can be considerably higher (e.g., the similarly sized state of Georgia has 170 species; Jensen et al., 2008). Kapfer and Brown assembled the knowledge and experience of 52 contributors, including most active herpetologists and conservation biologists in Wisconsin, and several from other states. The contributions ranged from co-authoring one to many species accounts plus natural history notes and introductory chapters. Co-editor Kapfer racked up the most contributions, which might be expected given his long and varied experiences conducting field work in Wisconsin, including his graduate studies. Co-editor Brown took the lead in writing and coordinating the turtle accounts, the reptile group he focused on for his graduate and postdoctoral research. Andrew Badje and Bob Hay stand out among the list of contributors. They have been involved in amphibian and reptile field research and conservation in Wisconsin for many years. Erik Wild produced the excellent, life-like images (colored pencil and pen and ink drawings) for the keys and throughout the book. The book is divided into eight preliminary chapters including: Introduction; Systematics and Classification; Some Prominent Figures in Wisconsin Herpetology; Past, Present, and Potential Future Landscapes of Wisconsin, with Emphasis on Amphibian and Reptile Distributions; Amphibians and Reptiles in Wisconsin Plant Communities; Introduction to Conservation and Management of Wisconsin’s Amphibians and Reptiles; Identification Keys for Amphibians and Reptiles in Wisconsin; and Introduction to Species Accounts. The introductory chapters are well done and provide a good background to the history and habitats of the state.
