SPARKS2 1Museum of Natural Science, Louisiana State University, Baton Rouge; [email protected] 2American Museum of Natural History, New York; [email protected] 3Hunter College High School, New York 4Health Professions & Human Services High School, New York 5Corresponding author Abstract A new species of Equulites is revealed using geometric morphometric techniques and is herein described. Based on features recovered in recent comparative analyses, members of Equulites have been diagnosed on the basis of internal and external male-specific traits related to their light-organ system (LOS; Sparks et al., 2005; Sparks, 2006; Sparks and Chakrabarty, 2007; Chakrabarty and Sparks, 2008). These sexually-dimorphic traits are hypothesized to allow males to signal to conspecific females in photic sexual displays using bacterially-generated luminescence (Woodland et al., 2002; Sasaki et al., 2003; Wada et al., 2005). The holotype and sole name-bearing type of Equulites leuciscus (BMNH 1858.4.21.243, 104.9 mm SL) is an adult female, and therefore lacks the diagnostic external feature of the LOS, a large, translucent flank patch, used to identify species in this genus. Geometric morphometric shape analysis of individuals ascribed to Equulites leuciscus, a traditionally widespread, “catch-all” taxon, reveals two discrete shape groups. Based on the results presented below, members of one of these groups correspond to a morphological variant that represents the new species (Equulites absconditus Chakrabarty & Sparks) described herein, whereas the other group corresponds to traditional E. leuciscus. In addition, the taxonomic status of Equula berbis Valenciennes, to which many female and poorly preserved specimens of the new species have erroneously been attributed, is reviewed and E. berbis is concluded to be a nomen dubium of uncertain placement beyond the family level. Key words: Indo-West Pacific, leiognathids, Photoplagios, taxonomy Introduction Equulites leuciscus Günther, 1860 was originally described from Ambon Island, Indonesia, and has historically been considered to be a geographically widespread species occurring throughout much of the Indo-West Pacific (from Madagascar and the Seychelles, to India, Sri Lanka, Indonesia and Australia; Woodland et al. 2001). Although this taxon has been considered to be one of the most widespread species of ponyfishes, there have been no comparative studies that have examined populations throughout its putative range. This is the first such study and it reveals the existence of geographically localized morphological variants. The female holotype of Equulites leuciscus (Fig. 1) has confounded taxonomic progress because it lacks the diagnostic LOS features typically associated with members of this genus (Sparks et al., 2005; Sparks, 2006; Sparks and Chakrabarty, 2007; Chakrabarty and Sparks, 2008). In addition, much of its original pigmentation pattern has been lost in preservation. To remedy this taxonomic problem and begin to understand geographic variation within this taxon, we compare geographic populations spanning the range of putative E. leuciscus. We use geometric morphometric techniques to determine the existence of different morphotypes and possibly distinct species. Accepted by M.R. de Carvalho: 11 Mar. 2010; published: 15 Apr. 2010 15 Two geographic populations of putative Equulites leuciscus are compared, and are referred to here as groups A (Fig. 2a) and B (Fig. 2b). The range of Group A spans mainly the Western Indian Ocean and South China Sea, from Madagascar to Sri Lanka and extending eastward to Taiwan. Individuals of Group A have relatively small heads, a concavity dorsal to the orbit, and a dorsal flank pigmentation pattern comprising dashed lines. These individuals are often catalogued in collections as E. leuciscus (or under the commonly used older synonyms, Leiognathus leuciscus or Photoplagios leuciscus) if males with a conspicuous translucent flank patch are present. Individuals of Group B occur mainly within the southeastern Indian Ocean, in Australian and Indonesian waters, and have larger heads, lack a concavity dorsal to the orbit, and possess a dorsal flank pigmentation pattern comprising wide vermiculate, circular patterns. Unfortunately, the holotype of E. leuciscus has lost its pigmentation pattern in preservation and is a uniform silver. This lack of pigmentation, and the absence of the male-specific diagnostic external features of the LOS, leaves only external shape as a source of evidence for testing whether Group A or Group B individuals represent Equulites leuciscus sensu strictu. Further confounding the taxonomy of this assemblage is the fact that female specimens (particularly of Group A) are often considered to represent another species, Equula berbis Valenciennes, in Cuvier and Valenciennes, 1835. Equula berbis, for which there is no type material and only a rudimentary original description, is an supposedly widespread taxon to which we hypothesize several distinct species have historically been attributed, including individuals of the new species described herein. In this study, we also review the taxonomic status of Equula berbis. Methods Specimens included in comparative analyses are listed in MATERIAL EXAMINED. Morphometric measurements, following Hubbs and Lagler (2004) were recorded to the nearest 0.1 mm using dial calipers and include: standard length (SL), head length (HL), body depth (BD), predorsal length (PDL), preanal length (PAL), prepelvic length (PPL), head width (HW), caudal peduncle length (CPL), caudal peduncle width (CPW), caudal peduncle depth (CPD), pectoral fin length (PTFL), pelvic fin length (PVFL), snout length (SNL), orbit diameter (OD), upper jaw length (UJL), lower jaw length (LJL), and interorbital width (IOW). Traditional morphometric measurements were taken for 17 different distances measured across the body of 131 individuals. For the geometric morphometric analysis, digital images were taken from the left side of 66 adult specimens. Landmarks (putatively homologous points on anatomical features) were chosen to best represent the external shape of the body (Fig. 3). Information unrelated to shape, including size, orientation and position, was removed by Generalized Least Squared (GLS) Procrustes superimposition. A Canonical Variates Analysis (CVA) was performed to show the axes on which groups are best discriminated by shape. The superimposition and CVA were completed in CVAgen (Sheets, 2001). Institutional abbreviations follow Leviton et al. (1985) except NTUM (National Taiwan University Museum, Taipei). Results There is overlap in the range of each of traditional morphometric measurements taken (Table 1). Notably, Group B individuals had a longer maximum SL (112.7 mm vs. 104.9 mm) and were generally more robust than individuals from Group A. Using traditional measurements, however, we were unable to distinguish between the two geographical groups examined. Canonical variates analysis recovered two distinct shape groups along CV 1 (Fig. 4). Male and female specimens were evenly distributed among the two groups (i.e., there are no gender specific shape trends). Canonical variate axis 1 is significant at the p <.001 level based on the Wilk’s lamda value (the sum of squares within groups divided by the total sum of squares within and between groups). An assignment test performed 16 · Zootaxa 2427 © 2010 Magnolia Press CHAKRABARTY ET AL. in CVAgen (Sheets, 2001) based on CV1 determined that all specimens had been correctly assigned to either Group A or B. The holotype of Equulites leuciscus was assigned to Group B in this test. Based on these data, we conclude that individuals of Group A constitute a new species in the genus Equulites, whereas members of Group B represent Equulites leuciscus sensu strictu. TABLE 1.

This genus is also diagnosed by the presence of dorsolateral lobes of the light organ that are hypertrophied and extend posteriorly into the gas bladder and lateral clearing of the silvery lining of the gas bladder.

SPARKS1 AND PAUL V. DUNLAP 2 ABSTRACT A phylogeny was generated for Leiognathidae, commonly known as pony®shes, using nu- cleotide characters from two mitochondrial genes. Results indicate that Leiognathidae com- prises two major clades, one consisting of species that exhibit internally sexually dimorphic light-organ systems (LOS), and the Leiognathus equulus species complex, whose members exhibit neither internal nor external sexual dimorphism of the LOS. Species with internally sexually dimorphic LOS generally also exhibit associated male-speci®c external modi®cations in the form of transparent patches on the margin of the opercle, the midlateral ¯ank, or behind the pectoral ®n axil. The L. equulus species complex is the sister group to all other leiog- nathids, and a new species, L. robustus, recovered within this clade is described herein. Results demonstrate that Leiognathus is paraphyletic, whereas Gazza and Secutor are each monophy- letic and are nested within the sexually dimorphic clade. The morphology of the LOS of non- sexually dimorphic leiognathids is compared to the more common sexually dimorphic state, and differences in these systems are discussed and illustrated. In the context of a family-level phylogeny, we can trace the evolution of the leiognathid LOS from a ``simple'' non-sexually dimorphic circumesophageal light organ to a complex and species-speci®c luminescence sys- tem involving not only major structural modi®cations of the light organ itself but also nu- merous associated tissues.

Threats from nutrient pollution, catchment scale modifications to land use and water flows are increasing. This is concerning for estuarine and coastal fisheries as estuarine producers are inextricably linked to land-derived nutrients and freshwater flows. In tropical estuarine ecosystems the complexity and variability of environmental, biological, and ecological factors culminate in a matrix of largely unknown causal relationships. Because of this, our knowledge of land use impacts on fisheries is limited. Additionally, the disjunction of current measurement scales and impact scales has reduced our ability to measure the resultant impacts on estuarine ecosystems. Therefore, to fully understand anthropogenic impacts on estuarine ecosystems, integrative measures of ecosystem health, functioning, and productive output are required.

  • Bioinvasions in the Mediterranean Sea 2 7
    Metamorphoses: Bioinvasions in the Mediterranean Sea 2 7 B. S. Galil and Menachem Goren Abstract Six hundred and eighty alien marine multicellular species have been recorded in the Mediterranean Sea, with many establishing viable populations and dispersing along its coastline. A brief history of bioinvasions research in the Mediterranean Sea is presented. Particular attention is paid to gelatinous invasive species: the temporal and spatial spread of four alien scyphozoans and two alien ctenophores is outlined. We highlight few of the dis- cernible, and sometimes dramatic, physical alterations to habitats associated with invasive aliens in the Mediterranean littoral, as well as food web interactions of alien and native fi sh. The propagule pressure driving the Erythraean invasion is powerful in the establishment and spread of alien species in the eastern and central Mediterranean. The implications of the enlargement of Suez Canal, refl ecting patterns in global trade and economy, are briefl y discussed.

  • A New Species of Ponyfish (Teleostei: Leiognathidae: Photoplagios)
    PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK, NY 10024 Number 3526, 20 pp., 7 figures, 2 tables September 8, 2006 A New Species of Ponyfish (Teleostei: Leiognathidae: Photoplagios) from Madagascar, with a Phylogeny for Photoplagios and Comments on the Status of Equula lineolata Valenciennes JOHN S. SPARKS ABSTRACT A new species of ponyfish in the genus Photoplagios is described from material collected in coastal waters of northeastern Madagascar. Photoplagios antongil, new species, is distinguished from congeners by the presence of a broad midlateral stripe and two darkly pigmented flank patches located ventral to the lateral midline, which are presumably translucent in life but darkly pigmented in preservative due to a concentration of melanophores. The new species is further distinguished from P. leuciscus, the only externally similar species occurring in the region, by the absence of a large translucent triangular patch on the flanks, a much shorter second dorsal-fin spine, a straight predorsal profile, pigmentation pattern on the upper flanks, absence of black pigment in the pectoral-fin axil, and exposed conical oral dentition in two distinct rows. A phylogeny for Photoplagios is provided based on the simultaneous analysis of anatomical features of the light-organ system and nucleotide characters. The taxonomic statusofEquula lineolata Valenciennes, in Cuvier and Valenciennes, 1835 is discussed, and the species is herein concluded to be a nomen dubium of uncertain placement beyond the family level. INTRODUCTION olatus (Valenciennes, in Cuvier and Valen- ciennes, 1835), P. moretoniensis (Ogilby, Photoplagios Sparks, Dunlap, and Smith, 1912), P. rivulatus (Temminck and Schlegel, 2005 comprises eight species: P.

Following global changes, Croatia is experiencing increasing problems due to the introduction of new species that include aliens (due to aquaculture activities and ship- ping) and species from other Mediterranean subregions that are extending their geographic range. This work provides a checklist of introduced species in Croatian waters. A total of 113 species (15 phytoplankton, 16 zooplankton, 16 macroalgae, 44 zoobenthic and 22 fish species) have been recorded in the eastern part of the Adriatic Sea, of which 61 species are alien and 52 introduced, due to climate change. Keywords: Alien species, range expansion, Croatia, Adriatic Sea, Mediterranean Sea. Introduction Considering all major characteristics, three biogeo- graphic regions can be recognized in the Adriatic Sea: a The Adriatic Sea is an elongated semi-enclosed basin shallow northern sub-basin and a deep southern sub-ba- in the Northeastern Mediterranean Sea.
