    RésuméThe unusually high proportion of brooding compared with broadcaster species among coastal Antarctic invertebrates has been traditionally interpreted as an adaptation to local environmental conditions. However, species with a planktotrophic developmental mode are ecologically dominant (in terms of abundance of individuals) along Antarctic coastal areas. Therefore, is the apparent ecological success of broadcasters related to their developmental mode? We argue that the present shallow Antarctic benthic invertebrate fauna is the result of two processes acting at different temporal scales. First, the high proportion of brooding species compared with coastal communities elsewhere corresponds to species-level selection occurring over geological and evolutionary times. Second, the ecological dominance of broadcasters is the result of processes operating at ecological timescales that are associated with the advantage of having pelagic larvae under highly disturbed conditions

    TitreAquatic macrophytes as tools for lake management
    AuteurMelzer, Arnulf
    RésuméAquatic macrophytes can serve as useful indicators of water pollution along the littoral of lakes. In Bavaria, the submerged vegetation of about 100 lakes has been investigated by SCUBA diving over the past decade to evaluate the state of nutrient pollution. All lakes are marl lakes located in the northern calcareous alps and the prealpine region. The lakes differ in size, morphology, water residence time, nutrient loading, trophic status, recreational activities, and other characteristics. In all cases the entire shoreline of the lakes has been investigated. Among the investigated lakes are the three biggest Bavarian lakes, i.e. Lake Chiemsee, Lake Starnberg and Lake Ammersee. Mapping of the submerged vegetation occurred in four different depth zones, and variable shoreline sections. The length of each section was determined by the uniformity of the vegetation; as it changed, a new section was designated. Within each section and zone species were recorded and abundance of all observed macrophytes was estimated semi-quantitatively on a five-point scale. Nine different groups of macrophytes were recognised, including, in total, 45 different species of macrophytes. On the basis of this catalogue of indicator species, in combination with the abundance of the species, a macrophyte index was devised, which ranges from 1 (unpolluted) to 5 (heavily polluted). Six groups of values of the macrophyte index, each represented by a different colour or grey-scale (in this publication), are presented to allow a clear illustration of the results. Important information for the successful restoration of lakes in Upper Bavaria has been obtained from the distribution patterns of the submerged vegetation. Many unknown waste water inflows or diffuse sources could be detected due to abrupt changes in the macrophyte index. Furthermore, the success of waste water removal by ring canalisation, resulting in a re-oligotrophication of many Bavarian lakes can be followed by changes in the macrophyte index.

    RésuméThe coastal echinoids found at Terre Adélie belong to two trophic groups. Herbivores are represented by the regular sea urchin, Sterechinus neumayeri, and deposit-feeders by three sympatric brooding species of Abatus. The coexistence of the latter is viewed in relation to long-term evolution of the clade, especially to brood protection, on the background of the tectonic and climatic history of the Antarctic continent.

    AuteurPoulin, Elie
    AuteurFéral, Jean-Pierre
    RésuméMarine invertebrates display a great variety of life-history traits and reproductive strategies . In echinoids, four patterns of larval development are generally recognized : planktotrophy, pelagic lecithotrophy, bottom dwelling, and brood protecting . Each broad type of free and protected development is found in all the oceans, but comparisons of the principal reproductive modes between different geographic regions have shown that they are not equally distributed . Frequency of pelagic development (planktotrophic and lecithotrophic) decreases from equator to Antarctic, where brood protecting becomes dominant . Numerous theories have been proposed to explain the richness of nonpelagic development in most marine invertebrates within the Southern Ocean . These theories can be grouped into three categories : (1) larval survival, where selection acts on larval ; (2) energy allocation ; and (3) dispersal . All of them consider the adaptative significance of brood protecting as the key to the success of this strategy in the Antarctic. However, the adaptative significance of brooding and the evolutionary success of this strategy in the Antarctic must be considered as two separate questions . To consider the problem at an evolutionary level, we have examined the consequences of different reproductive strategies on the genetic structure of species and on the long-term evolution of the Glade . We examine this problem in the case of echinoids, a Glade particularly well suited to addressing this question . In echinoids, the reduction of larval-stage duration is associated with a decrease in gene flow and consequently in the geographical scale of genetic differentiation . This allows us to reconsider the high-speciation-rate model, which leads to an increase in the number of low-dispersal species (isolation by distance) . This model, previously tested by means of fossils is not satisfactory in living echinoids . Thus, the model is rebuilt with the addition of differential extinction rate between planktotrophic and brooding species in relation with the climatic history of the Antarctic .

    AuteurSchatt, Philippe
    AuteurFéral, Jean-Pierre
    RésuméDevelopment of the brooding schizasterid Abatus cordatus, a subantarctic echinoid endemic to Kerguelen, is described. Females spawn nonbuoyant eggs 1300 μm in diameter, which are fertilized by elongated sperm (head 1 μm wide and 15 μm long). The main characteristics of this development are (1) incomplete cleavage beginning at the animal pole that becomes holoblastic, giving a filled wrinkled blastula 26 days after fertilization; (2) apparent (fate-mapping studies have not been done) external migration of mesenchyme cells, in the perivitelline space, from the animal to the vegetal pole during gastrulation while the archenteron invaginates; (3) hatching occurring at the end of the gastrulation (65 days after fertilization); (4) differentiation of the vestibule from a thickening of the oral epidermis as soon as the end of gastrulation is attained; and (5) production of a juvenile directly from the gastrula without any larval stage. The juvenile that leaves the brood chamber is 2 mm in diameter and about 250 days old. A. cordatus is a true completely direct developer (no larva and no metamorphosis). We propose to use (1) the term perigastrulation, as a tentative one until more definitive studies are available, to describe the hypothetical peculiar movement of cells during gastrulation and (2) the terms of direct development only for completely direct developing species and abbreviated development for species that have more or less transformed plutei.

    AuteurFéral, Jean-Pierre
    RésuméThis study examined the spatial distribution at different geographic scales of the echinoid Abatus cordatus which is endemic to the Kerguelen Islands. Special attention was paid to the nondispersal strategy of the species. It lives burrowed in the sediment and females brood their young in dorsal pouches. The dispersal of this species is therefore characterised by a limited mobility among adults and the lack of a free-swimming larval phase. Using SCUBA and dredging, A. cordatus was sampled all around Kerguelen. The spatial distribution from the island scale to the bay scale shows discontinuities at 2 levels: (1) at the island level favourable sectors (principally characterised by jagged coastline with numerous sheltered bays) are separated by linear coastline or swell exposed sectors; (2) at the bay scale A. cordatus lives in high density, isolated demes in shallow water of sheltered bays. A. cordatus was most numerous in sediments that ranged from medium to fine sand. The granulometry of the sediment and the lack of predation determine this aggregated spatial distribution pattern. Considering that the scale of larval dispersal is the consequence of spatial and temporal habitat structure, the non-dispersal strategy of A. cordatus is associated with a spatially varying but temporally constant habitat as predicted by theoretical models.

    AuteurPoulin, Élie
    AuteurFéral, Jean-Pierre
    RésuméEcological models suggest that individuals should not disperse in spatially varying but temporally constant environments. If such models are frequent in the literature, there are few studies that validates this assumption. In marine invertebrates, the larval stage is generally responsible for dispersal. One major way to reduce or avoid larval dispersal is to shorten or to lose the pelagic stage. The Antarctic and Subantarctic schizasterid echinoid species brood their offspring in dorsal pouches. The juvenile urchins are released directly onto the bottom around their mother. This situation correspond to an extreme strategy of non-dispersal. Studies on spatial structure show that Abatus cordatus, a species endemie to the Kerguelen Islands, lives in dense isolated populations generally located at the bottom of sheltered bays, where the hydrodynamism is weak enough to permit the maintenance of populations. For this non-dispersal species, the spatial and temporal habitat structure fit the theoretical model predictions: spatial heterogeneity (difference of carrying capacities between sites) and persistence of the populations. The consequences of such a strategy on the genetic structure of Abatus cordatus, as revealed allozyme polymorphism data, are that the populations are geographically differentiated as a result of the genetic drift and low migration rates between neighbouring populations. Moreover, genetic differentiation occurs over a scale of kilometers, contrary to the large scale differentiation generally reported for echinoid planktotrophic larvae species. Considering a geological rime scale, high differentiation rates leading to non-dispersal strategy as well as the extreme climatic and geographic position of Antarctica could explain the radiation of the echinoid brood protecti.ng genus and contribute to the understanding of the high proportion of marine brood protecting invertebrates species in this area.

    AuteurFéral, Jean-Pierre
    RésuméThe Schizasteridae includes a high proportion of brooding species. The brooding cycle of Abatus cordatus (a species endemic to Kerguelen) at an intertidal site in the "Golfe du Morbihan" is annual and lasts 8.5 months, from the end of March until the beginning of December. This cycle is reproducible among years, It is synchronous inside the Golfe between two intertidal sites. A displacement of about six months occurs at a deeper site (-50 m). The delay of the cycle and depth does not seem to be related because an open-sea intertidal site has a similar displacement of the brooding cycle. It depends on the gonadal cycle which itself depends on the availability of trophic resources. On this basis and samples taken in January annual brooding cycles are hypothetized to occur in 3 Antarctic species of Schizasteridae from Terre-Adélie in relation to the annual sea ice cover and restricted summer period of primary production.

    Résumé1.1. The gonad index (% fresh weight) of female Eumolpadia violacea is 14.1 ± 2.6% in July and 15.2 ± 5.7% in February. The water content is 73% for the body wall and nearly 90% for other body tissues.2.2. Protein levels are highest in all body areas except for the ovary where the lipid level is 13.9 ± 4.6%o fresh weight, compared to 9.2 ± 1.2%o for protein.3.3. Carbohydrate levels are different in July and February. Glycogen is the main carbohydrate changing in the longitudinal muscles, other reducing sugars change in the body wall, respiratory trees and ovary.4.4. The analyzed organic matter (AOM) represents 4.0±0.3% of the fresh weight of the organs in winter, and 5.1± 0.8% in summer. The change in mass of AOM is significant in the ovary (13 mg in July, 35 mg in February) where quantities of each biochemical component increase during this period.5.5. The energetic equivalent of AOM in the total body is 3496 ± 724 joules (835±173 calories) in July and 5753 ± 2278 joules (1374± 544 calories) in February. The change is 1.5× that in the gonad.6.6. The study of AOM of all body areas appears to be the least biased and the most convenient expression for intra- and inter-specific comparisons at the level of individuals and of populations (energy flow).

    AuteurWatson-Russell, C.
    RésuméA diver-operated coring system which takes undisturbed contiguous samples has been developed. A perspex space-frame localises a number of contiguous thin-walled tubes which can be driven into the sediment and from which core samples can be extracted. The corer consists of transparent tubing and low-pressure gate valve. The system is useful for describing small-scale spatial dispersion and for sampling patchy habitats. It is light, simple, inexpensive and is flexible with respect to the size and number of contiguous cores.

    TitreMechanoelectrical transduction in hyaluronic acid salt solution is an entropy-driven process
    AuteurBarrett, T. W.
    RésuméAn electrical potential develops between the ends of a column of hyaluronic salt solution displaced from a resting position by gentle pressure. A previous study demonstrated that such displacement changes the optical rotary dispersion properties of the salt, either increasing the rotation in the direction already shown by the salt before displacement or changing and increasing the rotation in the opposite direction, depending on the direction of the displacement. The present investigation demonstrates that the loss of bound water component across a membrane separating the solution and water is corelated with the extent of the column displacement. In addition, a return of the column to the position before displacement is correlated with a return of the water component across the membrane-but not at the same rate as the exodus. The data seem consistent with the hypothesis that the hyaluronic acid salt, when strained, adopts a less entropic configuration, releasing bound water and thus increasing the entropy of water component. This change in the distribution of entropy is reversible; i.e., Eddington's "time's arrow" is reversible with respect to the water component of the solution.

    RésuméThe possibilities of research using diving techniques, and the precautions required, at these two French southern islands are examined. Local conditions of topography and hydrography and potential dangers are reviewed from the point of view of an underwater biologist and in the particular context of diving. Emphasis is placed on the importance, in unfamiliar waters, of knowing one's personal capacities, which depend on good physical and psychological condition as well as equipment. Work in cold water, although often less efficient, is nevertheless quite feasible with the equipment available and some practical advice is given on this subject

    AuteurDrach, Pierre
    RésuméEn zone littorale profonde (portion de la zone néritiquesituée au-dessous du niveau des plus basses mers), aucun engin de récolte ne permet de travailler sur les fonds rocheux accidentés, les falaises sous-marines et les champs de gros blocs,. Notre connaissance de ces milieux est limitée aux premiers mètres qui font suite à la zone intercotidale et aux champs de petits blocs, reposant sur fonds meubles, accessibles à la drague. Les facies rocheux sous-marins exigent la pénétration directe de l'homme les tentatives jusqu'ici réalisées ont utilisé les scaphandres du type usuel (Petersen, 1908 et 1925; Kramp, 1925; Gislen, 193o; Zalokar, 1942) ou des casques de plongée (Kitching, Macan et Gilson, 1934). Casques et scaphandres usuels ont le triple inconvénient d'exiger que l'observateur repose sur fond plat, reste en position verticale et soit lié à son tuyau d'aération; tout cela exclut l'exploration des divers niveaux d'une falaise sous-marine et des fonds rocheux accidentés. Les nouveaux scaphandres autonomes, du type Cousteau-Gagnan, permettant une exploration libre, dans n'importe quelle position et sans aucune liaison avec l'extérieur, apparaissent comme les meilleurs instruments d'exploration sous-marine entre O et 50m.
