Written texts of the Iliad and the Odyssey achieved an unprecedented degree of standardization after 150 BCE, but what about Homeric texts prior to the emergence of standardized written texts? Orality, Textuality, and the Homeric Epics sheds light on that earlier history by drawing on scholarship from outside the discipline of classical studies to query from three different angles what it means to speak of Homeric poetry together with the word \"text\". 0Part I utilizes work in linguistic anthropology on oral texts and oral intertextuality to illuminate both the verbal and oratorical landscapes our Homeric poets fashion in their epics and what the poets were striving to do when they performed. Looking to folkloristics, part II examines modern instances of the textualization of an oral traditional work in order to reconstruct the creation of written versions of the Homeric poems through a process that began with a poet dictating to a scribe.0Combining research into scribal activity in other cultures, especially in the fields of religious studies and medieval studies, with research into performance in the field of linguistic anthropology, part III investigates some of the earliest extant texts of the Homeric epics, the so-called wild papyri.0By looking at oral texts, dictated texts, and wild texts, this volume traces the intricate history of Homeric texts from the Archaic to the Hellenistic period, long before the emergence of standardized written texts, in a comparative and interdisciplinary study that will benefit researchers in a number of disciplines across the humanities.

Jonathan L. Ready offers the first comprehensive examination of Homer's similes in the Iliad as arenas of heroic competition. This study concentrates primarily on similes spoken by Homeric characters. The first to offer a sustained exploration of such similes, Ready shows how characters are made to contest through and over simile not only with one another but also with the narrator. Ready investigates the narrator's similes as well. He demonstrates that Homer amplifies the feat of a successful warrior by providing a competitive orientation to sequences of similes used to describe battles. He also offers a new interpretation of Homer's extended similes as a means for the poet to imagine his characters as competitors for his attention. Throughout this study, Ready makes innovative use of approaches from both Homeric studies and narratology that have not yet been applied to the analysis of Homer's similes.

This article focuses on those Iliadic characters who fall in battle to the poem’s major heroes. Homer has various ways to make these characters minor, such as through processes of obscuring or typification or by focusing on a specific body part. By making a character minor, the poet signals that we need not attend to him. After he makes a character minor, the poet can suggest that in the process of being made minor a character paradoxically ends up diverting attention from another character, or he can portray minorness as marked by an inability to divert attention from another. The poet can present in one episode these two different visions of minorness and can make one character depict another as minor by using the tactics deployed by the narrator. This study accentuates the narratological complexities that arise in the poet’s depiction of minor characters. That complexity shapes our understanding of the Iliad’s concern with the distribution of narrative attention among all its characters.

The current capacity of environmental DNA (eDNA) to provide accurate insights into the biodiversity of megadiverse regions (e.g., the Neotropics) requires further evaluation to ensure its reliability for long‐term monitoring. In this study, we first evaluated the taxonomic resolution capabilities of a short fragment from the 12S rRNA gene widely used in fish eDNA metabarcoding studies, and then compared eDNA metabarcoding data from water samples with traditional sampling using nets. For the taxonomic discriminatory power analysis, we used a specifically curated reference dataset consisting of 373 sequences from 258 neotropical fish species (including 47 newly generated sequences) to perform a genetic distance‐based analysis of the amplicons targeted by the MiFish primer set. We obtained an optimum delimitation threshold value of 0.5% due to lowest cumulative errors. The barcoding gap analysis revealed only a 51.55% success rate in species recovery (133/258), highlighting a poor taxonomic resolution from the targeted amplicon. To evaluate the empirical performance of this amplicon for biomonitoring, we assessed fish biodiversity using eDNA metabarcoding from water samples collected from the Amazon (Adolpho Ducke Forest Reserve and two additional locations outside the Reserve). From a total of 84 identified Molecular Operational Taxonomic Units (MOTUs), only four could be assigned to species level using a fixed threshold. Measures of α‐diversity analyses within the Reserve showed similar patterns in each site between the number of MOTUs (eDNA dataset) and species (netting data) found. However, β‐diversity revealed contrasting patterns between the methods. We therefore suggest that a new approach is needed, underpinned by sound taxonomic knowledge, and a more thorough evaluation of better molecular identification procedures such as multi‐marker metabarcoding approaches and tailor‐made (i.e., order‐specific) taxonomic delimitation thresholds.

Quantifying the spatial distribution of taxa is an important prerequisite for the preservation of biodiversity, and can provide a baseline against which to measure the impacts of climate change. Here we analyse patterns of marine mammal species richness based on predictions of global distributional ranges for 115 species, including all extant pinnipeds and cetaceans. We used an environmental suitability model specifically designed to address the paucity of distributional data for many marine mammal species. We generated richness patterns by overlaying predicted distributions for all species; these were then validated against sightings data from dedicated long-term surveys in the Eastern Tropical Pacific, the Northeast Atlantic and the Southern Ocean. Model outputs correlated well with empirically observed patterns of biodiversity in all three survey regions. Marine mammal richness was predicted to be highest in temperate waters of both hemispheres with distinct hotspots around New Zealand, Japan, Baja California, the Galapagos Islands, the Southeast Pacific, and the Southern Ocean. We then applied our model to explore potential changes in biodiversity under future perturbations of environmental conditions. Forward projections of biodiversity using an intermediate Intergovernmental Panel for Climate Change (IPCC) temperature scenario predicted that projected ocean warming and changes in sea ice cover until 2050 may have moderate effects on the spatial patterns of marine mammal richness. Increases in cetacean richness were predicted above 40° latitude in both hemispheres, while decreases in both pinniped and cetacean richness were expected at lower latitudes. Our results show how species distribution models can be applied to explore broad patterns of marine biodiversity worldwide for taxa for which limited distributional data are available.

Bryconops Kner, 1858, includes two well defined subgenera based on morphological evidence, with each containing at least one species ( B . (Bryconops) caudomaculatus and B . (Creatochanes) melanurus ) with a very wide distribution, within which regional populations present color variations. To test if phenotypic variation is related to cladogenetic events, we performed tests for phylogenetic independence and determined the strength of convergence for color characters in relation to water type, as the variation between clear, black and white waters is considered to be one of the major driving forces in the evolution of Amazonian fishes. Color characters for fins above the median line of the body were generally found to be independent from phylogeny and the Wheatsheaf test strongly supports convergence of the dorsal fin color between populations of species in the same type of water, with a similar trend suggested for the color of the dorsal lobe of the caudal fin. This means that simple color characters cannot necessarily be relied upon for taxonomic revisions of the genus as local phenotypic variants may represent environmentally determined plasticity or convergent evolution. Further studies are required to determine the validity of these characters.

Mimesis is a relatively widespread phenomenon among reef fish, but the ontogenetic processes relevant for mimetic associations in fish are still poorly understood. In the present study, the allometric growth of two allopatric leaf-mimetic species of ephippid fishes, Chaetodipterus faber from the Atlantic and Platax orbicularis from the Indo-Pacific, was analyzed using ten morphological variables. The development of fins was considered owing to the importance of these structures for mimetic behaviors during early life stages. Despite the anatomical and behavioral similarities in both juvenile and adult stages, C. faber and P. orbicularis showed distinct patterns of growth. The overall shape of C. faber transforms from a rounded-shape in mimetic juveniles to a lengthened profile in adults, while in P. orbicularis, juveniles present an oblong profile including dorsal and anal fins, with relative fin size diminishing while the overall profile grows rounder in adults. Although the two species are closely-related, the present results suggest that growth patterns in C. faber and P. orbicularis are different, and are probably independent events in ephippids that have resulted from similar selective processes.

Squid of the genus Lolliguncula Steenstrup, 1881 are small bodied, coastal species capable of tolerating low salinity. Lolliguncula sp. are found exclusively in the New World, although only one of the four recognized species (Lolliguncula brevis) occurs in the Atlantic Ocean. Preliminary morphological analyses suggest that Lolliguncula brevis populations in the North and South Atlantic may represent distinct species. The principal objective of the present study was to verify the phylogenetic relationships within the genus and test for the presence of possible cryptic species. Both gene and species tree topologies indicated that Lolliguncula brevis specimens from the North and South Atlantic represent distinct phylogenetic clades. In contrast with previous studies, L. panamensis was identified as the basal species of the genus. Our results provide important insights into the phylogenetic relationships among the Lolliguncula specimens analyzed, and confirm the genetic separation of Lolliguncula brevis populations of the North and South Atlantic at the level of sister species.
