PICKUP, JAMES, et JOSEPH EDWARD IRONSIDE. « Multiple origins of parasitic feminization : thelygeny and intersexuality in beach-hoppers are caused by paramyxid parasites, not microsporidia ». Parasitology 145, no 3 (25 septembre 2017) : 408–15. http://dx.doi.org/10.1017/s0031182017001597.

Résumé :
SUMMARYWithin populations of the amphipod crustaceans Orchestia gammarellus and Orchestia aestuarensis, a proportion of females produce thelygenic (female-only) broods, which often contain intersexual individuals. This phenomenon is associated with the presence of two putative feminizing parasites, the paramyxid Paramarteilia orchestiae and the microsporidian Dictyocoela cavimanum, which frequently co-infect the same host. In order to determine which of the parasites causes feminization, Orchestia were resampled from the type locality of P. orchestiae in France and from another population in the UK. Breeding experiments indicated that female O. gammarellus infected with P. orchestiae produced a significantly higher proportion of female and intersex offspring than uninfected females, even in the absence of D. cavimanum. There was no difference in mortality between infected and uninfected broods, indicating that the paramyxid alters the sex ratio through feminization rather than male-killing. Although D. cavimanum also displays a female-biased prevalence in Orchestia populations, this is due to co-infection with P. orchestiae, indicating that the paramyxid, rather than the microsporidian, is the cause of feminization in these Orchestia populations.

Résumé :
The amphipod genus Orchestia is revised. It now includes 10 species of which three are new: O. forchuensis sp. nov. from north-eastern North America and Iceland., O. perezi sp. nov. from Chile and O. tabladoi sp. nov. from Argentina. Orchestia inaequalipes (K.H. Barnard 1951) is reinstated. The type species of the genus, O. gammarellus is redescribed based on material from Fountainstown, Ireland and a neotype is established to stabilize the species. The species was originally described from a garden in Leiden, far from the sea. Its true identity is unknown and no type material exists. Orchestia gammarellus (Pallas, 1776) is shown to be a sibling species group with members in both hemispheres of the temperate Atlantic as well along the Pacific coast of South America. A hypothesis for the establishment of the current distribution of Orchestia species is presented that extends back to the Cretaceous.

Résumé :
Seasonal variation in the structure of the amphipod community on the banks of Bizerte Lagoon was studied at Menzel Jmil (37°13′8″N 09°55′1″E) from July 2006 to June 2007. The distance between the actual sites of collection (sampling points) and the shoreline varied from 70 cm in September to 6.8 m in December. Specimens were mainly collected from under roots of Cymodocea nodosa and Suaeda maritima. In the laboratory, the specimens of Amphipoda (N = 10 645) were preserved in ethanol 70%, identified, sexed, and counted under a binocular microscope. Monthly counts varied between 553 (November) and 1240 individuals (April). Eight species of talitrids were identified, based on the specific characters of their gnathopods and pereiopods. Furthermore, the results show that the amphipod community of Bizerte Lagoon is primarily composed of 3 species, Orchestia mediterranea, Orchestia gammarellus and Orchestia montagui. The species last-mentioned represented the most frequent form in summer, whereas the other two, Orchestia mediterranea and Orchestia gammarellus, dominated in autumn. Orchestia stephenseni, Platorchestia platensis, Talorchestia deshayesii, Talitrus saltator, and Orchestia cavimana, were also found. A subsequent analysis of various diversity parameters of the amphipod community indicated a seasonal variation in abundance, species richness, and diversity.

Résumé :
Hypotheses concerning the modern distribution of Orchestia gammarellus (Crustacea, Amphipoda, Talitridae) and its causes in the North Atlantic are discussed. The synanthropic dispersal hypothesis of Henzler and Ingólfsson (2008) considers O. gammarellus as originating on the eastern shore of the North Atlantic and being transported by humans to Iceland and the western Atlantic shore (Newfoundland and the Maritime Provinces of Canada). The Eocene and natural dispersal hypothesis of Myers and Lowry (2020) proposes a geologically earlier origin of O. gammarellus when the west and east shores of the North Atlantic were still connected. Present day amphi-Atlantic distribution was explained by vicariance, with the vicariant event causing separation of O. gammarellus being continental drift drawing apart the west and east shores of the North Atlantic. A post-glacial natural dispersal hypothesis proposed herein, involves transport on ice floes or in driftwood from European shores to Iceland and the Atlantic Provinces of Canada. The small genetic distances amongst populations found by Henzler and Ingólfsson (2008) at the COI gene are inconsistent with the Eocene vicariance hypothesis. On evolutionary grounds, we question Myers and Lowry’s (2020) designation of the Icelandic and Canadian populations as a new species of Orchestia. Existing molecular and morphological data are insufficient to distinguish between human-aided dispersal and natural rafting.

Résumé :
The exposure of two species of talitrid amphipods (Orchestia gammarellus and Orchestia mediterranea) to a range of zinc and copper concentrations in solution has enabled the categorization of the mode of metal accumulation adopted by these supralittoral amphipods. Both species showed net accumulation of dissolved zinc and copper at all experimental exposures between 20 and 1000 μig Zng 1 and 13 and 1000 μg Cu 1 in artificial sea-water. Studies using Zn have shown that the zinc uptake rates of both species (0·430 μg Zn g d, SE 0·032 and 0·408 µg Zn g d, SE 0·073 for O. gammarellus and O. mediterranea respectively at 10°C in 31·6 μg Zn 1) are not significantly different, and are low in comparison with other crustaceans. Laboratory results are related to field conditions, and it is concluded that Firth of Clyde O. gammarellus are more dependent upon a food source in order to meet both their copper and zinc requirements than are O. mediterranea which are able to obtain sufficient metabolic copper from solution. The use of talitrid amphipods in zinc and copper biomonitoring programmes is also discussed.

The presence of an additional brain in female Orchestia gammarella induces the inhibition of yolky oocyte growth followed by their lysis. The graft, deprived of external influences, secretes a factor resembling vitellogenesis-inhibiting hormone. Oocytes undergoing primary vitellogenesis also appear to be target cells of vitellogenesis-inhibiting hormone.

Résumé :
AbstractThe digestive tract of animals harbors microbiota important for the host’s fitness and performance. The interaction between digestive tract bacteria and soil animal hosts is still poorly explored despite the importance of soil fauna for ecosystem processes. In this study, we investigated the interactions between the bacterial communities from the digestive tract of the litter-feeding, semi-terrestrial crustacean Orchestia gammarellus and those obtained from the environment; these organisms thrive in, i.e., soil and plant litter from salt marshes. We hypothesized that elevation is an important driver of soil and litter bacterial communities, which indirectly (via ingested soil and litter bacteria) influences the bacterial communities in the digestive tract of O. gammarellus. Indeed, our results revealed that elevation modulated soil and litter bacterial community composition along with soil organic matter content and the C:N ratio. Soil and plant litter differed in alpha diversity indexes (richness and diversity), and in the case of plant litter, both indexes increased with elevation. In contrast, elevation did not affect the composition of bacterial communities associated with O. gammarellus’ digestive tract, suggesting selection by the host, despite the fact that a large component of the bacterial community was also detected in external sources. Importantly, Ca. Bacilloplasma and Vibrio were highly prevalent and abundant in the host. The taxonomic comparison of Ca. Bacilloplasma amplicon sequence variants across the host at different elevations suggested a phylogenetic divergence due to host habitat (i.e., marine or semi-terrestrial), thus supporting their potential functional role in the animal physiology. Our study sheds light on the influence of the environment on soil animal–bacteria interactions and provides insights into the resilience of the O. gammarellus–associated bacteria to increased flooding frequency.

Résumé :
A technique is described for the in vitro culture of the eggs and embryos of amphipod crustaceans. The technique was used, with mixed success, to culture the eggs of four species of amphipod (Gammarus duebeni, Orchestia gammarellus, Gammarus pulex and Echinogammarus pirloti) through to hatching. Eggs of the brackish water G. duebeni showed good hatching success in culture (70–75%) over a wide range of experimental salinities (75–1250 mOsm kg1). The eggs of O. gammarellus showed higher mortality rates in culture (compared with G. duebeni), especially in more dilute salinities (300 mOsm kg1) in which they swelled greatly prior to disintegration. Survival and true growth (as distinct from osmotic swelling) of O. gammarellus embryos in dilute salinities were significantly im-proved by introducing embryos into culture at a later stage of development. Antibiotic treatment had no demonstrable effect on embryo survival or growth. Whilst difficult to culture using this method, the eggs of the fresh water G. pulex showed best hatching success on a very dilute saline medium (~40 mOsm kg1). The results are discussed in relation to the development of embryonic osmoregulation, the implications for brood pouch function and the potential for female control of the embryonic environment, especially in semi-terrestrial species.

Résumé :
Analysis of the total copper and zinc content of four species of talitrid amphipods, Orchestia gammarellus, O. mediterranea, Talitrus saltator and Talorchestia deshayesii throughout a complete spring/neap tidal cycle failed to reveal any significant effects of moulting upon body copper or zinc in any species. Moulting was synchronized to the lunar cycle only in T. saltator, taking place 5–7 days prior to a new moon. The fact that no significant changes in body metal concentrations took place with the moult cycle is discussed in relation to the use of talitrid amphipods in copper and zinc biomonitoring programmes.

Résumé :
A population of the supralittoral Orchestia gammarellus (Pallas) (Amphipoda: Talitridae), living in a percolating filter of a sewage treatment works has been studied over 12 months. The population showed a seasonal pattern of occurrence, few animals being collected during the winter. The sex ratio was biased significantly to females except during the breeding season when it did not deviate significantly from 1:1. Ovigerous females, never collected in high numbers (1–14 per month), were found from April to August, with peak occurrence in May/June. Juveniles were present throughout the year, but peak recruitment occurred in summer, following the period of reproduction by females. The smallest ovigerous female had a body length of 12.6 mm and the largest measured 20.0 mm. Egg numbers (5–31 per brood) increased with increasing female size and egg volume more than doubled during embryonic development. These findings are discussed in relation to the possible methods of colonization of this unique habitat and the influence of sewage on crustacean life-history traits.

Résumé :
The subunit composition of haemocyanin (Hc) from the semiterrestrial beachflea Orchestia gammarellus exhibited less heterogeneity and less (qualitative) between-individual variation than most decapod Hcs. While between-population variation was detected, no clear trends in Hc subunit composition from four populations along a salinity gradient were observed. Salinity had no detectable effect on Hc subunit composition or HcO2 binding in the laboratory. The degree of phenotypic variation in laboratory-held beachfleas was less than that displayed by any of the natural populations examined. Furthermore, examination of the O2 binding characteristics of five of the most common Hc phenotypes showed that each phenotype had the same O2 binding properties. Differences in Hc subunit composition between individuals and between populations may exist, but it should not be automatically assumed that such variation will have consequences for intrinsic Hc O2 binding properties.

Résumé :
Levels of pollution, including contamination by toxic metals, in the Thames estuary reduced over the last four decades of the 20th century. This 2014 study investigates whether the declines in the bioavailabilities of trace metals (Ag, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, Zn) have continued in the 21st century, using a suite of littoral biomonitors also employed in 2001 – the brown seaweed Fucus vesiculosus, the strandline, talitrid amphipod Orchestia gammarellus and the estuarine barnacle Amphibalanus improvisus. Bioaccumulated concentrations represent relative measures of the total bioavailabilities of each metal to the biomonitor over a previous time period, and can be compared over space and over time. Trace metal bioavailabilities varied along the estuary, and, in general, fell between 2001 and 2014, a reflection of the continuing remediation of the Thames estuary from its severely polluted state in the middle of the 20th century.

Résumé :
This study employed a suite of three biomonitors to investigate trace metal pollution in the Thames estuary, a region of significant clean-up of contaminants and the cumulative return of fauna and flora over the last two decades. The biomonitors chosen are the brown seaweed Fucus vesiculosus (bladder wrack), the barnacle Balanus improvisus and the talitrid amphipod crustacean Orchestia gammarellus, in order to obtain data on the bioavailabilities of Zn, Cu, Cd, Pb, Fe, Ag and Mn in the Thames estuary in 2001, as a basis for future comparisons as pollution is further reduced in the Thames. Accumulated metal concentrations in these organisms represent integrated records of the total bioavailabilities of the metals to that organism at that location over a previous time period, and comparisons of accumulated concentrations in a biomonitor between sites are indeed comparisons of the recent contaminant bioavailabilities to that biomonitor. All three biomonitors showed geographical differences in trace metal bioavailabilities along the Thames estuary. There was general agreement in the conclusions to be drawn from each of the three species used. Raised bioavailabilities of zinc, cadmium, lead, iron and manganese are present, particularly in the middle region of the Thames investigated, downstream of the effluent discharges of the sewage works at Beckton and Crossness.

Résumé :
Distribution and structure of intertidal macrobenthic communities in the Zwin nature reserve, a lagoonal inlet consisting of marsh and tidal flat habitats, was investigated using univariate and multivariate analyses. Macrobenthos community structure was related to environmental characteristics and discussed in the framework of the implemented extension of the nature reserve.Based on explorative multivariate techniques, five different sample groups (SGs) were distinguished, which were, in general, located in different habitats of the Zwin nature reserve. The ecologically most important SGs consisted of the highest macrobenthic density, diversity and highest densities of Nereis diversicolor and Scrobicularia plana; these important prey species for wading birds and fish occurred in the deep tidal inlet channels. This habitat was characterized by fine to medium sand sediment and strong tidal currents, guaranteeing water renewal at each high tide. Other SGs were found in less and erratically submersed and thus stressed areas (i.e. tidal pond, salt pans and shallow flats). These assemblages were characterized by typical r-strategists (i.e. Capitella capitata and Polydora cornuta) and typical supralittoral, mobile species (i.e. Orchestia gammarellus and Collembola spp.). Being ecologically most important, the extension of wide, tidal creeks should be a prime target within the future development and management of the nature reserve.
