We explored density-dependent fitness attributes and carry-over effects in Crawfish Frogs (Rana areolata) using a set of field enclosure experiments and a series of field data. Using field enclosures, we hypothesized that 1) at high densities, intraspecific competition would produce smaller Crawfish Frog juveniles that took longer to metamorphose; 2) at high densities, interspecific competition would also produce smaller Crawfish Frog juveniles that took longer to metamorphose; and 3) vertebrate (ambystomatid salamander) predation on Crawfish Frog larvae would reduce survivorship, but by releasing competition pressure would produce relatively larger tadpoles that metamorphosed earlier. Further, we hypothesized 4) that these enclosure results would apply to field data, and that fitness attributes in newly metamorphosed Crawfish Frogs would carry over to first-time breeding adults. Our results confirmed all four hypotheses. Specifically, in Crawfish Frogs, at high densities, both intra- and interspecific competition reduced size (length and mass) at metamorphosis (hypotheses 1 and 2), and predation reduced survivorship and increased size at metamorphosis (hypothesis 3). Finally, we observed density-dependent fitness effects on newly metamorphosed Crawfish Frog juvenile size (length and mass), and carry-over effects from the larval stage on juvenile survival, adult size, and breeding adult numbers (hypothesis 4). In the absence of predators, high densities of intra- and interspecific competitors had no effect on Crawfish Frog larval survivorship. We also present suggestive evidence for compensatory effects. We discuss the potential mechanisms underlying the patterns of these interactions, as well as the role of these relationships in informing management guidelines intended to ensure the future of this species of conservation concern.","PeriodicalId":10701,"journal":{"name":"Copeia","volume":"108 1","pages":"443 - 452"},"PeriodicalIF":2.6,"publicationDate":"2020-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48688763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kennedy (Eds.). 2018. Johns Hopkins University Press. ISBN 9781421426266. 277 p. $79.95 (hardcover).—The Diamond-backed Terrapin (Malaclemys terrapin) is not a freshwater turtle, and it is not a sea turtle. Truly a one-of-a-kind, the Diamond-backed Terrapin (hereafter, terrapin) is a brackish-water species that occupies a narrow strip of habitat along the Gulf of Mexico in the southern USA and Atlantic coastlines of the eastern USA, with an isolated population on the island of Bermuda. Along with being a habitat specialist, terrapins also have a colorful history and connection to people in the United States. Historically, this species was at the center of a culinary fad of the early 1900s for terrapin soup, while it is contemporarily connected with the coastal crab fisheries, where it is commonly taken as bycatch. The editors of the book, Willem Roosenburg and Vic Kennedy, are likely two of the best to tell this unique story, and they assembled 36 subject-area experts to craft 19 chapters about the species. Roosenburg has spent his career studying many aspects of the lives of terrapins, with his focusing on the status of populations in the Chesapeake Bay (a large estuary in the mid-Atlantic region of the northeastern USA bordered by the states of Maryland and Virginia), the impact of crab fisheries on terrapins, and the role of habitat restoration on species recovery. Kennedy has been vital to understanding the historical environment of the Chesapeake Bay and its fishery. Chapter 1, Introduction and History, provides an outline to the different sections of the book and introduces the reader to interesting aspects of the biology and ecology of terrapins. The author also poses some interesting questions for the reader to consider (e.g., if terrapins naturally dispersed to Bermuda, why aren’t they in Cuba? How did terrapins become one of the few tetrapods to inhabit brackish marshes?). Following the introduction, Part 1 of the book (Chapters 2–12) focuses on the Biology and Ecology of terrapins. Chapter 2 takes the reader through the numerous ways a researcher might capture, mark, and measure terrapins, while also providing methods for those who want to study their population and reproductive biology. This chapter also introduces other methods (e.g., molecular biology, tracking methods). While I appreciate the inclusion of this chapter and the myriad of ways to capture and study the species, it was an unexpected topic to start the book given the aforementioned colorful history of the species. In fact, this great history is not shared with the reader until Chapter 13, well after all the biology of the species is discussed. This is one organizational challenge I found with the book, and I will describe others later. The next three chapters detail the Evolutionary History and Paleontological Record (Chapter 3), Taxonomy (Chapter 4), and Molecular Ecology and Phylogeogra","PeriodicalId":10701,"journal":{"name":"Copeia","volume":"108 1","pages":"434 - 438"},"PeriodicalIF":2.6,"publicationDate":"2020-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42120110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ROBERT ‘‘BOB’’ FREDERICK INGER, died on April 12, 2019, at the age of 98. He is survived by his wife of 29 years, Tan Fui Lian, his brother and his wife, Morton and Sharon, of Wellfleet, Massachusetts, and his nephew and nieces, Daniel, Rachel, and Miriam. He was predeceased by his first wife, Mary Lee (1918–1985), and his parents, Jacob and Anna. Bob was born in St. Louis on September 10, 1920 and listed his ancestry as Polish on a Field Museum position application in 1946. He came to Chicago to attend the University of Chicago in 1937, based on the recommendation of a curator at the St. Louis Zoological Park (Emerson, 1989). Bob received his Bachelor of Science degree in 1942. After serving in General Patton’s Army in World War II as a ground map maker, he returned to the University of Chicago and completed his Ph.D. in zoology in 1954 (Stewart and Emerson, 2002). Bob’s association of over 75 years with the Field Museum of Natural History began when he volunteered as an undergraduate in the early 1940s. He and another student, Philip Jason Clark (1920–1964), decided to volunteer in the Division of Amphibians and Reptiles. Instead of the projects that volunteers were usually given, Curator Karl P. Schmidt (1890–1957) engaged them in a study of scale reduction in snakes. They published the resulting papers in Copeia in 1942 (Emerson, 1989). Bob became a staff member of the Field Museum in early 1946, when he was hired as an assistant to Clifford H. Pope (1899–1974) in Amphibians and Reptiles for 50 hours each month at 75 cents an hour. He spent his spare time conducting his doctoral research, and he held this position until he was appointed Assistant Curator of Fishes in 1949. Bob then succeeded Clifford H. Pope as Curator of Amphibians and Reptiles on January 1, 1954. In 1966 and 1967, he took leave from the Museum to serve as Program Director for Environmental Biology for the National Science Foundation. He left Amphibians and Reptiles again from 1970 to 1977 to become Chairman of Scientific Programs for the Museum, and later, Assistant Director for Science and Education. During his tenure as Assistant Director, Bob revised the curatorial promotion, ranks, and tenure policies to align more with those in universities. His efforts had a profound impact on raising the stature of research at the Museum. In 1978, he returned to his curatorial position in Amphibians and Reptiles where he continued until retirement in September 1994. Appointed Curator Emeritus in 1995, he passionately continued his research and fieldwork. For decades after retirement, he was in his museum lab almost every weekday. Early in his Field Museum career, Bob began to specialize in the systematics, ecology, and zoogeography of the fish, amphibians, and reptiles of Southeast Asia. His interest in these groups was strongly influenced by Karl P. Schmidt and led to his life-long association with the Field Museum.

Litmer, M. Freake, Christopher M. Murray","doi":"10.1643/CP-19-265","DOIUrl":"https://doi.org/10.1643/CP-19-265","url":null,"abstract":"Amphibians are currently facing widespread population declines, primarily due to the introduction of anthropogenic stressors, which have the potential to alter ecosystem dynamics and elicit long-term physiological responses resulting in overall population declines. Population assessments typically rely upon genomics, demography, and geographic isolation; however, when physiological parameters are included, mechanistic explanations for population declines can be determined. Rapid population assessments that can be related to specific microhabitat characteristics for management purposes can be achieved by implementing a chronic stress proxy, such as neutrophil: lymphocyte (N:L) ratios. As a long-lived habitat specialist, facing dramatic population declines with state and federally protected populations, the Hellbender (Cryptobranchus alleganiensis) is a good candidate species for applying N:L ratios to assess population vulnerability and habitat quality. This study used N:L ratios as a proxy of chronic stress among Hellbender populations to determine environmental variables potentially correlated with chronic stress. Additionally, comparisons of N:L ratios were made among Hellbender populations to examine applicability of this method for assessing among-population differences. Of the microhabitat variables assessed, high conductivity, low pH, and low dissolved oxygen correlated with elevated N:L ratios. In addition, N:L ratios differed significantly among Hellbender populations, which suggests the utility of N:L ratios as an indicator of population-level differences. Specifically, where traditional methods lack the ability to detect concerns, physiological assessment suggested certain populations may be of concern in regard to experiencing chronic stress. Including physiological parameters in viability and vulnerability assessments more frequently, such as the one described here, can provide evidence of population concerns earlier than traditional methods, and allow for better management strategy by elucidating specific environmental variables contributing to stress.","PeriodicalId":10701,"journal":{"name":"Copeia","volume":"108 1","pages":"403 - 415"},"PeriodicalIF":2.6,"publicationDate":"2020-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42783159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study investigated how differences in nutrient availability affect sperm size in Diamond-backed Watersnakes (Nerodia rhombifer). We compared body size and sperm morphometrics between two populations with differing nutrient availability: a naturally occurring lake and a commercial fish farm. We hypothesized that prey availability affects sperm morphometrics. Our null hypothesis was that there would be no significant difference in sperm morphometrics between populations, whereas our alternative hypothesis was that the snakes from the fish farm would have significantly longer sperm. We measured total sperm length, sperm head length, sperm tail length, and snout–vent length (SVL). We then used two-tailed t-tests and AIC model selection to test our hypotheses. SVL was not correlated with sperm size. Furthermore, none of the sperm morphometrics were significantly different between the two populations. Finally, a nearly 1:1 correlation between sperm tail length and total sperm length was found. AIC model selection corroborated these results by choosing only sperm head length and sperm tail length as significant predictors of total sperm length. This is the first published study to explicitly compare sperm morphometrics between two populations of the same snake species. Additional studies of this nature are required to corroborate whether lack of significant differences in sperm morphometrics among snake populations are common.","PeriodicalId":10701,"journal":{"name":"Copeia","volume":"108 1","pages":"376 - 380"},"PeriodicalIF":2.6,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43806630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ancient Teays River, a principal drainage of the eastern United States, engaged in several ephemeral connections with neighboring palaeodrainages prior to and during the Pleistocene, when cyclical glacial advance and retreat reconfigured the region's fluvial systems. This study assayed DNA-sequence diversity at one mitochondrial (mtDNA) and three single-copy nuclear DNA (scnDNA) loci from the Tonguetied Minnow (Exoglossum laurae), a species distributed as four disjunct populations, one each within the Upper Great Miami, Upper Allegheny, Upper Genesee, and New rivers. Mitochondrial DNA variation revealed that the New River harbors the highest diversity (h = 0.73) and that the Tonguetied Minnow is composed of two ancient lineages, a Teays River lineage and a Pittsburgh River lineage. Analyses of the scnDNA loci revealed sharing of alleles among populations of E. laurae and between the Tonguetied Minnow and its only congener, the Cutlip Minnow (E. maxillingua), sampled from the Roanoke and Potomac rivers. The probability of interspecific hybridization in the New and Upper Genesee rivers was estimated as 0.16 and 0.34, respectively, but it is likely that some degree of incomplete lineage sorting contributed to these estimates. Probabilities of interspecific hybridization for Cutlip Minnow were 0.62 and 0.65, for the Roanoke and Potomac rivers, respectively, and might reflect ancient hybridization resulting from stream capture events involving these drainages by the Teays River. Management strategies should focus on maintaining the security of the Pittsburgh River lineage in the Upper Great Miami and Upper Allegheny River drainages. Finally, insights into the Tonguetied Minnow's rather convoluted taxonomic history are few, but genetic variation is inconsistent with subspecies status for Tonguetied Minnow in the Upper Great Miami River drainage.","PeriodicalId":10701,"journal":{"name":"Copeia","volume":"108 1","pages":"381 - 391"},"PeriodicalIF":2.6,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46783765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
