During recent field expeditions to an Amazonian region in eastern Guiana Shield (Serra do Navio, state of Amapá, northern Brazil), we collected and recorded calls of a species of Adelophryne, a diminutive leaf-litter-dwelling, direct-developing frog genus. After a careful integrative taxonomic evaluation using morphological, molecular, and bioacoustic data, we concluded that the series of specimens collected represent a new taxon, which we describe herein. The new species of Adelophryne is distinguished from all ten congeners by the following combination of character states: (1) male SVL = 12.5 mm; female SVL = 13.0–14.4 mm; (2) tympanic membrane present; (3) tympanic annulus present, incomplete; (4) vomerine teeth absent; (5) finger terminal discs absent; (6) tips of Fingers I–IV mucronate; (7) finger pads present (formula 1–1–2–1); (8) three phalanges in Finger IV; (9) dorsum smooth; (10) cloacal flap absent; (11) multi-note advertisement call composed of non-pulsed notes; (12) the call dominant frequency (4,802–5,706 Hz) coincides with the fundamental harmonic. Our study describes the eleventh species of Adelophryne, and, despite the increase in taxonomic knowledge within the past few years, there are still some species in the genus lacking a formal taxonomic description.

The ecology of many ectotherms depends heavily on their ability to navigate the surrounding thermal environment in a manner that maintains body temperature (Tb) within or near some optimal temperature range at least some of the time. From April–December 2016, we measured shell temperatures (Ts) and water temperatures (Tw) in two Spotted Turtle (Clemmys guttata) populations in southeastern Georgia using iButton temperature loggers. We attached radio transmitters and iButtons to the carapace of adult Spotted Turtles (n = 18 and 11 in each population, respectively) in early spring. Temperature loggers recorded a Ts measurement every 90 minutes (accuracy = 0.5°C), and we restricted our analyses to temperatures recorded between sunrise and sunset. Monthly mean Ts ranged from 12.3±3.4 to 27.1±2.7°C (SD), and seasonal variation accounted for a majority of the observed variation in temperatures. We found a strong positive correlation between weekly mean Ts and weekly mean Tw at one site that remained flooded throughout the study (P < 0.0001, R2 = 0.99). Tw could not be measured at the other site because it dried completely early in the study. Spotted Turtles did occasionally (<5% of total temperature observations) bask to raise Ts above that of the surrounding Tw. Gravid females achieved significantly higher daily maximum temperatures (26.2°C) than males (24.5°C) during the four weeks surrounding egg development (P = 0.043). In general, Spotted Turtles at the southern end of their range appear to spend a majority of their time conforming to environmental temperatures that often fall within the preferred range for the species.

A new species, Careproctus ambustus, is described from 64 specimens based on evidence from morphological and molecular data. Specimens of Careproctus ambustus, new species, have been historically misidentified as the common Blacktail Snailfish, C. melanurus. The new species is distinguished from C. melanurus by its higher numbers of vertebrae (62–66 vs. 56–62 in C. melanurus), dorsal-fin rays (57–63 vs. 53–58), and anal-fin rays (51–55 vs. 46–51), and longer pelvic disc (14.1–21.2 vs. 12.6–20.7 % HL). In addition, the new species differs from C. melanurus by seven base pairs within a 492-base-pair region of the cytochrome oxidase c subunit 1 region, a 1.4% sequence divergence. Careproctus ambustus, new species, is found at depths of 58–1,172 m and ranges from Japan, through Alaska, to the west coast of Vancouver Island, British Columbia, where its distribution overlaps with C. melanurus, which ranges from southern Alaska and British Columbia to Baja California.

When color pattern variation is co-adapted with other biological features, distinct color morphs may be separated along divergent niche axes, and data on niche partitioning can provide insight into how distinct color morphs are maintained over spatiotemporal scales. The Eastern Red-backed Salamander, Plethodon cinereus, contains two common color morphs (striped and unstriped) that differ along several trait axes in addition to coloration. Previous studies from a single population have suggested that dietary composition represents an important axis of ecological differentiation between morphs of P. cinereus. To determine if morphs partition prey resources over space and time, we collected stomach contents from morphs across six populations that ranged in color morph frequency from 100% striped to >99% unstriped, and sampled each population in a spring and a fall season. From each population and season, we also sampled leaf litter invertebrates to quantify morph differences in prey selection. Based on previous studies, we predicted striped morph diet would consist of higher quality prey in polymorphic populations, whereas in monomorphic populations, we predicted both morphs would have a more variable diet due to ecological release from intermorph competition. In the two polymorphic populations we examined, one showed no evidence of diet differences and the other mirrored differences reported from previous studies. There was no change in dietary breadth between polymorphic and monomorphic populations, and thus no signature of dietary release. Our results show there is a high degree of overlap between dietary and leaf litter invertebrates, suggesting both morphs of P. cinereus are generalist predators. Finally, we found dietary composition varied across seasons and populations, which demonstrates the importance of examining morph traits over spatial and temporal scales.

Dragon Lizards of Australia: Evolution, Ecology and a Comprehensive Field Guide. Jane Melville and Steve K. Wilson. 2019. Museums Victoria Publishing. ISBN 9781921833496. 416 p. AU$49.95/US$35.00 (softcover).— Dragon lizards are iconic reptiles of Australia. Frill-necked Lizards. Thorny Devils. Bearded Dragons. These are some of the well-known stars of the Aussie dragon world, but there is much more to this diverse group than these large or bizarre famous species. Authors Jane Melville and Steve Wilson are well positioned to produce this book on Australian dragons. Melville has focused her research almost exclusively on agamids over the last 20 years, and her research has greatly enhanced our systematic knowledge of these animals. At the time of this volume’s publication, her group had described 20 dragon species (now 25, over half of which are Tympanocryptis), and raised many more from subspecies to full species or revalidated species or genera in synonymy. Her first-hand knowledge of dragons comes through decades of fieldwork that has taken her nearly over the entire continent, searching for new species and collecting specimens and tissue samples for genetic analyses. Steve Wilson is Australia’s most prolific—and arguably the best—reptile photographer. His series with Gerry Swan, A Complete Guide to the Reptiles of Australia (Wilson and Swan, 2017), is about to be published in a 6 edition, and he has other quality publications such as Australian Lizards: A Natural History (Wilson, 2012). With Wilson’s name on the cover, you immediately know you are in for a visual feast. His photographs not only sparkle with clarity and excellent color balance, but they are well-composed aesthetically. Owing to his knowledge of the animals, images have been picked to tell a story and show insightful angles, not just the standard portrait. Even within pages, images seem to have been chosen to show dragons in different postures from different perspectives. Dragon Lizards of Australia is best described as an intermediate-level book that is probably more comfortable on a coffee table than in a rucksack when heading to the field. At just over 400 pages long, it is a bit heavy for only one group of Australian reptiles—after all, where would the room in your bags be for the gecko, skink, and snake books if each were covered in as much detail? The book is available as a paperback only, with a nearly square shape of 19 3 21 cm, and just over 2 cm thick. The size and heavy paper cover function well, as the pages open—and stay open—quite nicely, making it easy to flip back and forth among sections. The burnt-orange color of the frontispiece and leading page of the sections is pleasing to the eye, and it evokes the arid zone where dragons are plentiful. The orange also mirrors the background of the stunning front cover featuring a Thorny Devil (Moloch horridus). Even the little rectangle of orange in the upper corners of the pages was a nice touch, although perhaps differe
澳大利亚龙蜥蜴：进化、生态学和综合野外指南。简·梅尔维尔和史蒂夫·威尔逊。2019年，维多利亚博物馆出版社。是9781921833496。416页49.95澳元/35.00美元（软封面）龙蜥蜴是澳大利亚的标志性爬行动物。流苏颈蜥蜴。荆棘魔鬼。胡子龙。这些是澳大利亚龙界的一些著名恒星，但这个多样化的群体比这些大型或奇异的著名物种要多得多。作家简·梅尔维尔和史蒂夫·威尔逊有能力撰写这本关于澳大利亚龙的书。在过去的20年里，梅尔维尔的研究几乎完全集中在龙舌兰上，她的研究极大地增强了我们对这些动物的系统了解。在本卷出版时，她的团队已经描述了20种龙（现在有25种，其中一半以上是Tympaocryptis），并将更多的龙从亚种提升为完整物种或重新验证的同义物种或属。她对龙的第一手知识来自于几十年的实地调查，这些调查几乎带她走遍了整个大陆，寻找新物种，收集标本和组织样本进行基因分析。史蒂夫·威尔逊是澳大利亚最多产，也可以说是最好的爬行动物摄影师。他与Gerry Swan合作的系列《澳大利亚爬行动物完整指南》（Wilson and Swan，2017）即将出版6版，他还有其他高质量的出版物，如《澳大利亚蜥蜴：自然史》（Wilson，2012）。威尔逊的名字出现在封面上，你马上就知道你将迎来一场视觉盛宴。他的照片不仅清晰、色彩平衡，而且构图优美。由于他对动物的了解，人们选择图像来讲述故事，并展示有洞察力的角度，而不仅仅是标准的肖像。即使在页面中，图像似乎也被选择来从不同的角度展示龙的不同姿势。《澳大利亚龙蜥蜴》最好被描述为一本中等水平的书，当它去野外时，放在咖啡桌上可能比放在帆布背包里更舒服。这本书只有400多页，对于一组澳大利亚爬行动物来说有点沉重——毕竟，如果每本书都有同样多的细节，你包里的壁虎、石皮和蛇书会放在哪里？这本书只有平装本，形状接近正方形，长19 3 21厘米，厚度刚刚超过2厘米。大小和厚重的纸张封面功能良好，因为页面可以很好地打开并保持打开状态，可以很容易地在各个部分之间来回翻转。章节首页和首页的焦橙色令人赏心悦目，让人想起了龙出没的干旱地带。橙色也反映了令人惊叹的封面背景，封面上有一个荆棘魔鬼（Moloch horridus）。即使是页面上角的橙色小矩形也很好看，尽管每个部分可能使用了不同的颜色。一条橙色虚线出现在《龙属快速指南》和《野外指南》部分，将龙的属名或种名与正确的龙照片联系起来。这个元素在现场指南中并没有太大的作用，但确实有助于打破白色背景。此外，直角形状也在某种程度上唤起了南澳大利亚东北角和艾尔湖盆地——这并不是一件坏事，因为那里有很多有趣的龙。前75页的标题是进化、生态学和生物学，它们介绍了多样性、行为、生理学和其他适用于所有龙的重要主题。在介绍部分的第一页，一些文本以不规则形状的橙色斑点出现，使这些页面看起来很有趣，这表明观众包括不同的博物学家和爱好者，他们对中等水平的材料和学术巨著感到满意。但直到《词汇表》（Glossary）中，这些斑点才再次出现，它们充当了人物说明的背景，使这些出现看起来像是一个被抛弃的想法。第一节介绍了龙舌蜥，特别是澳大利亚龙舌蜥（两栖纲），包括一系列漂亮的彩色地图，显示了世界上三个主要类群的分布（第4页）。解释了无齿龙（Acrondon）和鬣蜥（胸膜齿龙）之间的齿列差异，以及它们形态的一般特征（例如，发育良好的四肢有五个手指、长尾和带有龙骨、脊椎和结节的无光泽鳞片）。来自世界各地的鬣蜥和龙舌蜥的许多照片使人们对澳大利亚的辐射有了正确的认识。

L ESLIE WILLIAM KNAPP was born in Auburn, New York on November 17, 1929 and died May 17, 2017 in Maryland. He graduated from Port Byron Central School, Port Byron, New York in 1947. Les is survived by his wife Betty who runs a greenhouse business, Loch Less Farm, and their two sons. Les entered the College of Agriculture of Cornell University in September 1948 and received his B.S. degree in 1952. He enlisted in the U.S. Army and served from 1952 to 1954. He entered the University of Missouri in February 1955 and completed his master’s degree in August 1958, ‘‘A distributional study of the fishes of the upper White River, Missouri,’’ studying under Arthur Witt, Jr. In September 1958 he began his ichthyological studies under Edward C. Raney at Cornell University and received his Ph.D. degree in February 1964 studying the systematics of the Rainbow Darter, Etheostoma caeruleum. This was a busy time for darter studies at Cornell with Robert V. Miller, William Richards, and me all studying different groups of darters under the guidance of Edward Raney. From Cornell, Les was hired by the Smithsonian Oceanographic Sorting Center in Washington, D.C., which was just getting started, to process material collected by expeditions such as the International Oceanographic Campaign. Les published seven studies on darters from 1963 to 1976, including joining me to produce a catalog of all type specimens of all the darters (Collette and Knapp, 1967). Les then turned his efforts to studying two families of marine fishes, the flatheads, Platycephalidae and Bembridae, publishing 24 papers from 1973 to 2012, seven with Hisashi Imamura from Japan. He also completed the sections on Bembridae and Platycephalidae which are still in press in the long-delayed volumes of Fishes of the Western Indian Ocean (Table 1).

Les published seven studies on darters from 1963 to 1976, including joining me to produce a catalog of all type specimens of all the darters (Collette and Knapp, 1967). Les then turned his efforts to studying two families of marine fishes, the flatheads, Platycephalidae and Bembridae, publishing 24 papers from 1973 to 2012, seven with Hisashi Imamura from Japan. He also completed the sections on Bembridae and Platycephalidae which are still in press in the long-delayed volumes of Fishes of the Western Indian Ocean (Table 1).","PeriodicalId":10701,"journal":{"name":"Copeia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45230961","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}
A new species of glyptosternine catfish of the genus Exostoma is described from the Chakpi River, a tributary of the Chindwin-Irrawaddy drainage in northeastern India. The new species can be distinguished from congeners of the Chindwin-Irrawaddy drainage except E. chaudhurii and E. vinciguerrae in having an adipose fin confluent (vs. separate) with the upper procurrent caudal-fin rays. It differs from E. chaudhurii in having anastomosing, rounded (vs. parallel) striae on the anterolateral surfaces of the lips and from E. vinciguerrae in having shorter adipose-fin base (29.1–32.3% SL vs. 35.4–39.4). This is the sixth species of Exostoma known from the Chindwin-Irrawaddy drainage.

Previous studies have reported egg attendance as the most common protective behavior among the Neotropical frog family Centrolenidae. However, research on the effect of parental care and other factors thought to affect offspring survival is still missing for a great number of species. Here, we performed field observations during day and night to associate male-only care, habitat characteristics, and environmental variables with egg clutch survival in the understudied glass frog, Hyalinobatrachium talamancae. We conducted 34 nest survival models for 39 egg clutches considering constant daily survival rates, temporal variation in the survival probability, and other biotic and abiotic variables thought to affect the survival of embryos. We found that egg attendance was strongly associated with egg clutch survival in H. talamancae. Our results showed similar degrees of parental investment during day and night, accounting for extensive caring periods over one or multiple clutches as paternal care did not hinder re-mating in this species. Egg clutches exhibited daily survival rates of 0.93±0.02, often reaching pre-hatching stages when attended by males. Our results may thus suggest that egg attendance is a major, if not predominant, determining factor of embryo survival in H. talamancae. This study contributes to the understanding of the natural history associated with paternal care in H. talamancae and provides insight into the evolution of prolonged male-only care in the family Centrolenidae.

The anti-equatorial labrid Pseudojuloides elongatus has a wide but disjunct distribution across the Western Pacific and Eastern Indian Oceans, with populations occurring in Western Australia, southern Japan, and the southwest Pacific Ocean. Principal component analysis of morphological characters and coalescent-based species-tree estimates of mitochondrial and nuclear DNA markers suggest that these populations are under incipient stages of divergence. The three allopatric populations differ strongly in coloration patterns of both sexes, particularly in terminal males, suggestive of reproductive isolation. We redescribe Pseudojuloides elongatus on the basis of nine paratypes and two additional specimens from eastern Australia and Norfolk Island, and describe two new species, Pseudojuloides crux, new species, from Western Australia, and P. paradiseus, new species, from southern Japan. The complex is distinguished from other members of the genus in sharing the following combination of characters: body elongate; dorsal-fin rays IX,12; pectoral-fin rays 12; no median predorsal scales; and usually 27 lateral-line scales. We briefly comment on anti-equatorial biogeographical patterns and Pseudojuloides argyreogaster from the Western Indian Ocean.
