Abstract:

Abstract The early evolution of dinosaurs is documented by abundant postcranial material, but cranial material is much rarer and comparisons of cranial features among early dinosaurs are limited to only a few specimens. Here, we fully detail the osteology of the unusual early-diverging dinosaur Daemonosaurus chauliodus from the latest Triassic Coelophysis Quarry in northern New Mexico, USA. The taxon possesses a unique and curious suite of character states present in a variety of early dinosaurs, and the morphology of D. chauliodus appears to link the morphology of Herrerasaurus with that of later diverging eusaurichians. Our phylogenetic analyses places D. chauliodus at the base of dinosaurs and our interpretation of the unusual mix of character states of D. chauliodus does not lead to a firm conclusion about its nearest relationships or its implications for the evolution of character state transitions at the base of Dinosauria. The combination of character states of D. chauliodus should not be ignored in future considerations of character evolution in early dinosaurs. As one of the last members of the earliest radiation of saurischians in the Carnian–early Norian, D. chauliodus demonstrates that members of the original diversification of dinosaurs survived until nearly the end of the Triassic Period.

Abstract:

In the mid North Atlantic Chauliodus sloani is caught mainly between 55° and 29° N, while the majority is caught north of 35° N. The greatest density is found around 40° N. Chauliodus danae has the northern limit of its distribution at about 45° N. C. danae, in particular the smaller specimens, shows clear vertical migration and has food preference, while C. sloani does not show such migration and is most probably a random feeder. In both species there is a significant increase in length from south to north.

Abstract:

The mesopelagic fish fauna of the Newfoundland Basin is relatively depauperate. The specimens that were taken, 6760 in number, represented 51 species and 28 families. The majority were rare, 22 species occurring in only one sample and only 8 species occurring in more than 50% of the samples. The myctophid Benthosema glaciale made up 83.5% of all fish collected. Other species included Stomias boa ferox, Bathylagus euryops, Protomyctophum arcticum, and Chauliodus sloani. There are fewer small species in the Newfoundland Basin than in similar samples in the Slope Water. Specimens of B. glaciale and C. sloani were generally larger in the Newfoundland Basin than in the Slope Water.

Abstract:

New data about slender orb-weaving species of the cosmopolitan genus Tetragnatha are presented. Tetragnatha chauliodus (Thorell, 1890) and Tetragnatha tenuissima O. Pickard-Cambridge, 1889 are redescribed, including one synonymy for each species and the first record of the first species to the Neotropical region. Also, three new species are herein described, all based on males and females. Tetragnatha megalocera new species is recorded exclusively from Brazil (Espírito Santo, Rio de Janeiro, Rio Grande do Sul and São Paulo states), while Tetragnatha renatoi new species is recorded from Venezuela, Argentina (Misiones) and Brazil (Paraná, Pernambuco, Rio Grande do Sul, Rondônia, Santa Catarina and São Paulo states). Finally, Tetragnatha chiyokoae new species is described from Yunnan province (China) and Okinawa (Japan), with an additional record for Taiwan. Furthermore, Tetragnatha exilima (Mello-Leitão, 1943), Tetragnatha filigastra Mello-Leitão, 1943 and Tetragnatha lactescens (Mello-Leitão, 1947) are nomina dubia.

Full text

Abstract:

A new genus and species of pennellid copepod, Protosarcotretes nishikawai n. g., n. sp., is described on the basis of an ovigerous female infecting a Pacific viperfish Chauliodus macouni collected from the deep-waters of Suruga Bay, Japan. The new genus exhibits the most plesiomorphic states in the first to fourth legs of pennellids, and is differentiated from two closely related pennellid genera Sarcotretes and Lernaeenicus by the morphology of the oral appendages. Two species of the genus Lernaeenicus are transferred to the new genus as Protosarcotretes multilobatus (Lewis, 1959) n. comb. and Protosarcotretes gnavus (Leigh-Sharpe, 1934) n. comb. The host specificity and life cycle of deep-sea pennellids are discussed. Sarcotretes scopeli Jungersen, 1911 and Cardiodectes bellottii (Richiardi, 1882) show low differentiated host-specificity, while P. nishikawai seems to be limited to the Stomiidae, which are rare hosts of pennellids, in contrast to the Myctophidae family. In the Pennellidae family, two patterns of the life cycle are found: with or without naupliar stages.

Full text

Abstract:

This study was designed to describe the occurrence and distribution of Stomiidae along the Brazilian central coast. Three oceanographic cruises were made in the Brazilian central coast during the spring/1998, winter/1999 and autumn/2000. Stomiid larvae were very rare in the samples, occurring in 13% of the sampled stations. A total of 102 stomiid larvae were collected representing 11 species, some of which could only be identified to genus: Aristostomias sp., Astronesthes sp., Bathophilus sp., Eustomias sp., Melanostomias sp., Stomias sp., Chauliodus sloani, Flagellostomias boureei, Photonectes mirabilis, Photostomias guernei and Stomias affinis. All species identified have already been recorded from the Brazilian coast as adults, except for P. guernei, first recorded in this study. Most taxa were distributed both in the northern and southern regions of the study area, including the banks of the Vitória-Trindade Ridge. Stomias sp. was the most abundant taxon among all groups and was widely distributed along the study area. The species C. sloani and F. boureei were only collected in the south and north regions, respectively.

Abstract:

Stomach contents were analysed from three species of beaked whales which mass-stranded shortly after a naval exercise conducted in the Canary Islands in September 2002. Animals from such mass strandings often contain freshly ingested food in their stomachs and can provide a more reliable guide to feeding habits than other strandings. Food remains recovered from seven Cuvier's beaked whales (Ziphius cavirostris) consisted mainly of oceanic cephalopods, the most numerous being Taonius pavo, Histioteuthis sp., Mastigoteuthis schmidti and Octopoteuthis sicula. Many of the cephalopod species found in the diet appear to undertake daily vertical migrations, being found in shallower waters during the night and moving to deeper waters during the day. Single specimens of Blainville's beaked whale (Mesoplodon densirostris) and Gervais' beaked whale (Mesoplodon europaeus) had eaten both fish and cephalopod prey. The most numerous prey remains belonged to gadid fish and viperfish (Chauliodus sp.) respectively. These results are consistent with the limited published data on diet in these species, with Mesoplodon species having a relatively higher proportion of fish in the diet whereas Ziphius specialises on cephalopods.

Abstract:

The Lumbrera Formation is the uppermost unit of the Salta Group, which crops out in northwestern Argentina. The paleoenvironment of the Lumbrera Formation is interpreted as a perennial lake deposited under temperate climatic conditions during the early to middle Eocene. Its fossil content is made up of palynomorphs, insects, crocodiles, turtles, lizards, and mammals, besides an ichthyofauna formed by cichlids, poeciliids and dipnoans. †Plesioheros chauliodus is described based on a single individual from this formation, which was fossilized as a lateral view impression (missing anal and caudal fins). It can be distinguished from other cichlids by a moderately deep body, enlarged anterior dentary teeth bearing subapical cusp, a low abdominal vertebral count (10), five canal openings in the dentary, and XI + 12 dorsal-fin rays. A phylogenetic analysis, using the matrix by Kullander (1998), recovered †Plesioheros within Heroini. This species was recovered most closely related to Australoheros and to the deep-bodied South American heroins. The occurrence of an Eocene Heroini, as well as of other cichlid lineages in the same stratigraphical level, is evidence of an ancient diversification in this family. This ancient age supports the hypothesis that the Cichlidae originated on Gondwana.

Full text

Abstract:

The oldest theropod dinosaurs are known from the Carnian of Argentina and Brazil. However, the evolutionary diversification of this group after its initial radiation but prior to the Triassic–Jurassic boundary is still poorly understood because of a sparse fossil record near that boundary. Here, we report on a new basal theropod, Daemonosaurus chauliodus gen. et sp. nov., from the latest Triassic ‘siltstone member’ of the Chinle Formation of the Coelophysis Quarry at Ghost Ranch, New Mexico. Based on a comprehensive phylogenetic analysis, Daemonosaurus is more closely related to coeval neotheropods (e.g. Coelophysis bauri ) than to Herrerasauridae and Eoraptor . The skeletal structure of Daemonosaurus and the recently discovered Tawa bridge a morphological gap between Eoraptor and Herrerasauridae on one hand and neotheropods on the other, providing additional support for the theropod affinities of both Eoraptor and Herrerasauridae and demonstrating that lineages from the initial radiation of Dinosauria persisted until the end of the Triassic. Various features of the skull of Daemonosaurus , including the procumbent dentary and premaxillary teeth and greatly enlarged premaxillary and anterior maxillary teeth, clearly set this taxon apart from coeval neotheropods and demonstrate unexpected disparity in cranial shape among theropod dinosaurs just prior to the end of the Triassic.

Currently, the immature stages of this genus are completely unknown. Here we describe the larvae of A. laboissierei for the first time. The larval characters, especially the strongly developed respiratory tubes on the abdominal segment VIII, support a close relationship between Anachauliodes and the eastern Nearctic Chauliodes Latreille, 1796.

Abstract:

Spiders in the genus Cybaeus L. Koch (Araneae : Dictynoidea : Cybaeidae) are common forest-floor inhabitants in western North America and Japan. Here we establish an initial phylogenetic framework for North American Cybaeus. Morphological details for eight proposed species groups are given, and these results, combined with molecular analyses of one nuclear and one mitochondrial gene for six of the eight species groups, suggest that North American Cybaeus species are contained in two broad clades, one Holarctic and one Nearctic (primarily Californian). The Holarctic clade contains the tetricus and angustiarum species groups, which contain mostly widely distributed species. The Californian clade includes the adenes, aspenicolens, consocius, devius, septatus and tardatus species groups, all of which have very restricted ranges. The genus Cybaeus and the Palaearctic species C. tetricus (C.L. Koch) (type species of the genus) and C. angustiarum L. Koch are redescribed and illustrated. A key to species groups is provided. Nine new species endemic to the western Nearctic and included in the molecular analyses are described and illustrated: C. paralypropriapus Bennett, sp. nov. and C. waynei Bennett, sp. nov. (tetricus group); C. sanbruno Bennett, sp. nov. (adenes group); C. thermydrinos Bennett, sp. nov. (aspenicolens group); C. penedentatus Bennett, sp. nov. and C. vulpinus Bennett, sp. nov. (consocius group); C. chauliodous Bennett, sp. nov. and C. somesbar Bennett, sp. nov. (septatus group); and C. gidneyi Bennett, sp. nov. (unplaced).

Craspedochaeta basalis brasiliensis Sóos, 1961 syn. nov. and C. piceoflava (Sóos, 1962) syn. nov. are synonymized with Craspedochaeta annulipes (Johnson, 1913) comb. nov.; C. minuta Sóos, 1962 syn. nov., C.atra (Kertesz, 1903) syn. nov. and C. albohalteria Sóos, 1962 syn. nov., are synonymized with C. concinna (Williston, 1896). Craspedochaeta sasakawai nomen nov. is provided as a replacement name for C. pleuralis (Curran, 1936), which is a junior homonym of C. pleuralis (Williston, 1896) comb. nov. Agonistic behaviour is recorded for the first time in Craspedochaeta, with photographs showing male-male interactions in the Bolivian species C. pullipleura. A key is provided for all 31 New World Craspedochaeta species and the relationships of the C. concinna and C. transversa groups are discussed on the basis of male and female morphological characters. Species of Craspedochaeta are recorded for the first time in North America, with C. weemsi found in Florida, C. concinna found in Florida and New Mexico, and C. annulipes found in Georgia, Maryland, Mississippi, North Carolina, and Texas.

Full text

Abstract:

Family-, genus- and species-level groups in the family Clusiidae (Diptera: Schizophora) are catalogued, providing reference to occurrences of these taxa in the literature, including all those relevant to nomenclature. Full synonymies are provided, including generic combinations for species, and the collection locality, depository and sex of primary type specimens. Published species distributions are provided, noting country and biogeographic region; specimen data representing new country records for species are listed. The Clusiidae are known from 636 species in 14 genera and three subfamilies, with many additional species expected. Nearly half of all described species are Sobarocephala, with 269 species, followed by the clusiodine genera Heteromeringia (86 species), Allometopon (68), Hendelia (53 species), Czernyola (50 species) and Clusiodes (31 species); the remaining eight genera (seven extant, one fossil) are smaller, consisting of 1 to 16 species. Two other fossil genera, Acartophthalmites Hennig and Xenanthomyza Hennig, are also treated here, but are unlikely to belong to the family. Taxa formerly considered Clusiidae are listed.

Abstract:

AbstractMesopelagic fishes are numerically the most important vertebrate group of all world’s oceans. While these species are increasingly threatened by anthropogenic activities, basic biological knowledge is still lacking. For instance, major uncertainties remain on the behaviour, ecology, and thus functional roles of mesopelagic micronektivores, particularly regarding their interactions with physicochemical features. Here, we examine the trophic ecology, habitat, and migratory behaviour of the viperfish (Chauliodus sloani)—a poorly known and abundant deep-sea species—to further understand the ecology and thus functional role of mesopelagic micronektivores. Moreover, we explore how physical drivers may affect these features and how these relationships are likely to change over large oceanic areas. The viperfish heavily preys on epipelagic migrant species, especially myctophids, and presents spatial and trophic ontogenetic shifts. Temperature restricts its vertical distribution. Therefore, its trophodynamics, migratory behaviour, and functional roles are expected to be modulated by the latitudinal change in temperature. For instance, in most tropical regions the viperfish stay full-time feeding, excreting, and serving as prey (e.g. for bathypelagic predators) at deep layers. On the contrary, in temperate regions, the viperfish ascend to superficial waters where they trophically interact with epipelagic predators and may release carbon where its remineralization is the greatest.

Abstract:

Abstract Vertebrates use cone cells in the retina for colour vision and rod cells to see in dim light. Many deep-sea fishes have adapted to their environment to have only rod cells in the retina, while both rod and cone genes are still preserved in their genomes. As deep-sea fish larvae start their lives in the shallow, and only later submerge to the depth, they have to cope with diverse environmental conditions during ontogeny. Using a comparative transcriptomic approach in 20 deep-sea fish species from eight teleost orders, we report on a developmental cone-to-rod switch. While adults mostly rely on rod opsin (RH1) for vision in dim light, larvae almost exclusively express middle-wavelength-sensitive ("green") cone opsins (RH2) in their retinas. The phototransduction cascade genes follow a similar ontogenetic pattern of cone- followed by rod-specific gene expression in most species, except for the pearleye and sabretooth (Aulopiformes), in which the cone cascade remains dominant throughout development. By inspecting the whole genomes of five deep-sea species (four of them sequenced within this study: Idiacanthus fasciola, Chauliodus sloani; Stomiiformes; Coccorella atlantica, and Scopelarchus michaelsarsi; Aulopiformes), we found that deep-sea fish possess one or two copies of the rod RH1 opsin gene, and up to seven copies of the cone RH2 opsin genes in their genomes, while other cone opsin classes have been mostly lost. Our findings hence provide molecular evidence for a limited opsin gene repertoire and a conserved vertebrate pattern whereby cone photoreceptors develop first and rod photoreceptors are added only at later developmental stages.
