Abstract The Mascarene Petrel (Pseudobulweria aterrima), an endemic seabird of Réunion Island, is one of the rarest and least known birds in the world. In this note we report on light-induced mortality in this species at Réunion Island, in the Indian Ocean. Throughout most of the twentieth century, when Réunion Island's population was relatively small, only three birds were found dead or dying. After instituting in 1996 a program encouraging the public to rescue downed seabirds, we received eight Mascarene Petrels, among which seven were banded and released. Four birds were fledglings attracted by lights while on their first flight to sea. These findings show for the first time since the end of the nineteenth century that Mascarene Petrels still breed at Réunion. All fledglings were found in March (late austral summer), suggesting a synchronous summer breeding season. We discuss past and present effects of urban lights on this small population and propose a conservation plan. Rescate de Pseudobulweria aterrima, un Ave Marina Críticamente Amenazada de la Isla Reunión, Océano Indico Resumen. Pseudobulweria aterrima, un ave marina endémica de la isla Réunion, es una de las aves más raras y menos conocidas del mundo. En esta nota exponemos los resultados de un estudio sobre mortalidad en esta especie provocada por la iluminación artificial en la isla Reunión. A través de la mayor parte del siglo veinte, cuando la población en la isla era relativamente pequeña, sólo tres aves fueron encontradas muertas o muriendo. Luego de instituir en 1996 un programa que incentivó al público a rescatar aves abatidas, recibimos ocho aves de las cuales siete fueron anilladas y liberadas. Cuatro de las aves eran volantones jóvenes que fueron atraídos por las luces durante su primer vuelo hacia el mar. Estos resultados muestran por primera vez desde fines del siglo diecinueve que P. aterrima se sigue reproduciendo con éxito en esta isla. Los cuatro volantones fueron encontrados en el mes de marzo, lo que nos hace suponer que la reproducción se realiza sincrónicamente durante el verano austral. Discutimos las consecuencias pasadas y actuales de las luces artificiales sobre esta pequeña población y proponemos un plan de acción para su conservación.

A New Species

The genus Smacigastes Ivanenko & Defaye, 2004 (Harpacticoida, Copepoda) is the most primitive genus in the family Tegastidae Sars, 1904, occurring in deep-sea chemosynthetic environments, such as hydrothermal vents, cold seeps, whale falls and wood falls. Our exploration of the Onnuri Vent Field, the sixth active hydrothermal vent system in the Central Indian Ridge, resulted in the discovery of a new species in the genus Smacigastes. A detailed morphological analysis of S. pumilasp. nov. reveals that it most resembles S. barti Gollner, Ivanenko & Martínez Arbizu, 2008, described from a hydrothermal vent in the East Pacific Ridge; the new species can be distinguished from the existing species by the 8-segmented female antennule, the absence of an abexopodal seta on the antennary basis, the mandibular exopod represented by a single seta and the exopod of the first leg with five setae. This is the first record of Smacigastes in the Indian Ocean. A dichotomous key to species of the genus Smacigastes worldwide is provided.

Four new species of Anatomidae are described: Anatoma herberti n. sp. with strong axial sculpture on the shoulder and base; A. austrolissa n. sp. with almost smooth sculpture except for axial cords in the adumbilical half of the base; A. boucheti n. sp. with sunken protoconch and selenizone that starts after more than one teleoconch I whorl; and A. fl exidentata n. sp. with a highly modifi ed radula, shared only with A. austrolissa, among known anatomid species. Three of the species are only known from the Indian Ocean, while the more deep-water A. austrolissa is known from Reunion Island and New South Wales, Australia. The radula of A. flexidentata and A. austrolissa is strikingly different from that of other Anatomidae and Vetigastropoda in that it has flexible equally-shaped teeth in the central field and filamentous teeth in the marginal fi eld. Similar radular morphologies are known from Calliostomatidae.

Sergestes edwardsii Kröyer, 1855 species group is composed of 9 species: S. semissis  (Burkenroad, 1940);  S. gibbilobatus (Judkins, 1978);  S. orientalis (Hansen, 1919);  S. geminus (Judkins, 1978);  S. tantillus (Burkenroad, 1940); S. consobrinus (Milne, 1968) California Current Form;  S. consobrinus (Milne, 1968) Central Form; S. edwardsii (Kröyer, 1855); S. brevispinatus (Judkins,1978).  The bathypelagic  shrimps  belonging  to  the  genus Sergestes  are  being studied from the  IIOE  material  for  its  taxonomy  and distribution.  Two species, S. brevispinatus (Judkins,1978) and  S. edwardsii (Kröyer, 1855), have been collected by the research vessels  ANTON BRUNN, ARGO, DIAMANTINA, METEOR, OSHORO MARU and VARUNA in the Indian Ocean for the first time.  Sergestes edwardsii is broadly distributed throughout the tropical Atlantic; it occurs from the New Land Plaza, Canada, to the wide of the Great Power of the North; throughout the Caribbean and Gulf of Mexico. Records at high northern latitudes in the Western Atlantic are probably due to transport by the Gulf Stream (Judkins, 1978). In Brazil it occurs in Para, in the Archipelago of Are Peter and Sao Paulo, Great River of North Fermando De Noronho  (D’Incao, F., 1995, 1998). Specimens of the present material are housed in the Marine Reference Collection and Resource Centre (MRC&RC), University of Karachi.

Abstract. Atmospheric carbon monoxide (CO) and methane (CH4) mole fractions are measured by ground-based in situ cavity ring-down spectroscopy (CRDS) analyzers and Fourier transform infrared (FTIR) spectrometers at two sites (St Denis and Maïdo) on Reunion Island (21∘ S, 55∘ E) in the Indian Ocean. Currently, the FTIR Bruker IFS 125HR at St Denis records the direct solar spectra in the near-infrared range, contributing to the Total Carbon Column Observing Network (TCCON). The FTIR Bruker IFS 125HR at Maïdo records the direct solar spectra in the mid-infrared (MIR) range, contributing to the Network for the Detection of Atmospheric Composition Change (NDACC). In order to understand the atmospheric CO and CH4 variability on Reunion Island, the time series and seasonal cycles of CO and CH4 from in situ and FTIR (NDACC and TCCON) measurements are analyzed. Meanwhile, the difference between the in situ and FTIR measurements are discussed. The CO seasonal cycles observed from the in situ measurements at Maïdo and FTIR retrievals at both St Denis and Maïdo are in good agreement with a peak in September–November, primarily driven by the emissions from biomass burning in Africa and South America. The dry-air column averaged mole fraction of CO (XCO) derived from the FTIR MIR spectra (NDACC) is about 15.7 ppb larger than the CO mole fraction near the surface at Maïdo, because the air in the lower troposphere mainly comes from the Indian Ocean while the air in the middle and upper troposphere mainly comes from Africa and South America. The trend for CO on Reunion Island is unclear during the 2011–2017 period, and more data need to be collected to get a robust result. A very good agreement is observed in the tropospheric and stratospheric CH4 seasonal cycles between FTIR (NDACC and TCCON) measurements, and in situ and the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) satellite measurements, respectively. In the troposphere, the CH4 mole fraction is high in August–September and low in December–January, which is due to the OH seasonal variation. In the stratosphere, the CH4 mole fraction has its maximum in March–April and its minimum in August–October, which is dominated by vertical transport. In addition, the different CH4 mole fractions between the in situ, NDACC and TCCON CH4 measurements in the troposphere are discussed, and all measurements are in good agreement with the GEOS-Chem model simulation. The trend of XCH4 is 7.6±0.4 ppb yr−1 from the TCCON measurements over the 2011 to 2017 time period, which is consistent with the CH4 trend of 7.4±0.5 ppb yr−1 from the in situ measurements for the same time period at St Denis.

In this paper, I will discuss the methodological problems raised by the museography of a forthcoming museum on Reunion Island, the Maison des civilisations et de l'unité réunionnaise. One of the museum's goals is to retrace visually the itineraries of the processes of creolisation in the Indian Ocean that led to the creation of a singular culture, the Creole indiaoceanic culture. How to visualise the multiple layers of signification at work, the traces and fragments of languages, imaginaries, rituals, practices travelling throughout the ocean, the dynamic of loss, transformation, translation and recreation of forms, rituals, practices in the itineraries of people? I will first present the museum, its context and goals, then suggests ways of “making visual” elements of the Indian Ocean’s long history, and finally, discuss the challenges of imagining a museum of the present in the Indian Ocean world.
