Abstract:

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.

Abstract:

The frequently studied amphipod genus Talitrus Latreille, 1802, long thought to be monotypic is shown here to include three species. Two species had already been recognized as distinct species. Talitrus cloquetii Audouin, 1826 and T. platycheles Guérin, 1832, but both had long been reduced to synonymy with T. saltator. All three species are described and figured and a key is provided for their identification. Because of the extensive literature associated with the name Talitrus saltator (sensu lato) we have attempted to assign published records to their appropriate species.

Abstract:

Abstract Four Talitridae species have been recorded in the southern Baltic Sea, including two indigenous species – Talitrus saltator, Deshayesorchestia deshayesii, and two presumably non-indigenous ones – Cryptorchestia garbinii, Platorchestia platensis. It has been twelve years since Platorchestia platensis was recorded for the first time. The distribution and abundance of talitrids have not been studied since the 1990s. Therefore, the main objective of this research was to document the occurrence in Talitridae in the region in order to determine whether non-indigenous P. platensis has spread and whether it co-occurs with indigenous species. Talitrids were recorded at 20 out of 43 sampling sites. T. saltator occurred both along the coast of the open sea and in the Gulf of Gdańsk. The remaining species were found only around the gulf. P. platensis was more abundant than other species and its density was positively correlated with wrack biomass. Our studies have shown that the area of T. saltator occurrence has decreased during the last two decades. Non-indigenous species P. platensis co-occurred with all other Talitridae species, whereas C. garbinii co-occurred only with P. platensis.

Abstract:

AbstractThe talitrid amphipod Talitrus saltator has a wide distribution along European Atlantic and Mediterranean sandy shores. Previous research had estimated genetic differences among populations with iso-enzyme electrophoresis, as well as differences in behavioural adaptation related to ecological features. In this study morphometric differences among four Mediterranean (Italian coasts) and three Atlantic (Portuguese and Welsh coasts) populations were estimated, which may give information on population dynamics and adaptability to environmental constraints. The localities chosen differed with regard to the following characteristics: sheltered/exposed shorelines, tidal/non-tidal shores, presence/absence of detritus, Atlantic/Mediterranean climate, high/low human frequentation. Samples of each population were collected in a standardized way and fresh individuals were weighed, their body lengths and eye diameters were measured, and the number of eggs in the female brood-pouches and the articles of each antenna were counted. The results were as follows: (i) an unbalanced sex ratio in each population studied, females being more abundant than males; (ii) significant differences between Mediterranean and Atlantic population groups as to weight and body length distributions, the Atlantic talitrids being larger than the Mediterranean ones; (iii) differences in eye colour, normally black in this species, but one Mediterranean and two Atlantic populations presented a certain proportion of blue-eyed individuals; (iv) right-left asymmetry of eye surface areas (right eye bigger than left one) in all populations, with one exception. The differences found among populations do not seem to follow a geographic cline, but could depend on ecological features of the localities. L'amphipode talitride Talitrus saltator a une large distribution le long des cotes sableuses de l'Atlantique europeen et de la Mediterranee. Des recherches anterieures ont evalue les differences genetiques parmi les populations par electrophorese iso-enzymatique, ainsi que les differences de comportement adaptatif en relation avec les facteurs de l'environnement. Dans cette etude, les differences morphometriques parmi quatre populations mediterraneennes (cotes italiennes) et trois populations atlantiques (cotes portugaises et galoises) ont ete evaluees, ce qui peut donner des informations sur les dynamiques de population et sur l'adaptabilite aux contraintes de l'environnement. Les localites choisies different en ce qui concerne les caracteristiques suivantes: lignes cotieres abritees/exposees, cotes a maree ou non, presence/absence de detritus, climat atlantique/mediterraneen, haute/basse frequentation humaine. Les echantillons de chaque population ont ete preleves suivant un meme standard et les individus frais ont ete peses, la longueur du corps et le diametre de l'oeil mesures, le nombre d'oeufs dans la poche incubatrice et les articles de chaque antenne comptes. Les resultats ont ete les suivants: (i) une sex ratio non equilibree dans toutes les populations etudiees, les femelles etant plus nombreuses que les males; (ii) des differences significatives entre les groupes de populations atlantiques et mediterraneens, quant a la distribution des poids et des longueurs du corps, les individus atlantiques etant plus grands que les mediterraneens; (iii) des differences dans la couleur de l'oeil, normalement noir chez cette espece, mais une population de l'Atlantique et deux de Mediterranee presentaient une certaine proportion d'individus a yeux bleus; (iv) une asymetrie droite-gauche de la surface de l'oeil (oeil droit plus gros que le gauche) dans toutes les populations, avec une exception. Les differences observees entre les populations ne semblent pas suivre un gradient geographique, mais pourraient dependre des caracteristiques ecologiques des localites.

Abstract:

Adult individuals of Talitrus saltator were tested for celestial orientation in a plexiglass bowl covered with colour filters of different wavelengths. Results show that T. saltator can recognize the sun and use it for orientation only at γ <450 nm. At γ >500 nm, the sight of the sun (and sky) only induces phototactic behaviour. It has also been confirmed that an important celestial orienting factor is perceived in the UV range. Variations in populations from diversely oriented coastlines are discussed. Preliminary results of electroretino-graphic responses indicate the presence of at least two visual pigments in the eye and a steep decrease in sensitivity for γ >500 nm.

Abstract:

Orientated navigational behaviour in Talitrus saltator (Montagu) was studied throughout the diel cycle. Amphipods released at the centre of a circular arena without an artificial horizon on the periphery showed random escape directions at all times of day. In the presence of an artificial light/dark boundary the escape direction was random at night but was towards the boundary by day. The onset of significantly orientated navigation occurred just before the time of dawn and persisted in a typically circadian manner for 7 days in amphipods kept in continuous darkness.The phase of the circadian rhythm could be reset in altered light/dark cycles. Phase changes were directly proportional to imposed L:D phases over the range —4 to + 12 h, except that shifts from —2 to +2 h induced no phase change in the orientation rhythm. The endogenous pattern of change of orientated navigation is discussed in relation to the nocturnal endogenous locomotor activity rhythm of Talitrus and its diel pattern of foraging and burrowing behaviour on sandy beaches.

Abstract:

The sandhopper Talitrus saltator is common on sandy beaches at different latitudes. Therefore, behavioural variations allowing them to cope with a wide range of environmental variation are expected. To test the hypothesis that behavioural adaptations to natural environments are characterised by different salinities, we compared two behaviours (substrate choice and escape from immersion) of two T. saltator populations from a Mediterranean (high salinity) and a Baltic Sea (low salinity) sandy beach. T. saltator preferred to burrow in the high salinity substrate, irrespective of its beach of origin. Regarding orientation to escape from immersion, Baltic sandhoppers always oriented landwards, whereas Mediterranean sandhoppers showed a significant orientation landwards only when immersed in high salinity sea water. These behavioural traits matched the different environments, and this adaptation capability can be used as a model to analyse the response of a keystone species to environmental changes.

Abstract:

L'etude porte sur un crustace amphipode, talitrus saltator (crustacea, amphipoda) qui utilise des reperes astronomiques, pour atteindre la zone de sable humide qui lui est vitale. Cette capacite d'astroorientation se manifeste sans qu'une experience prealable sur un bord de mer quelconque ne soit necessaire. Il existe en fait une composante hereditaire qui influence la direction de fuite qu'adoptent les jeunes talitres inexperimentes. Dans une premiere partie, des etudes comportementales, histologiques et electrophysiologiques ont ete menees, dans le but de mettre en evidence le role que joue la lumiere polarisee du ciel bleu dans ce phenomene d'astroorientation. Il apparait que le talitre utilise la lumiere polarisee du ciel pour s'orienter et la percoit: dans l'ultra-violet lorsque l'ouverture sur le ciel est superieure a 30 ou 40 degres. Un mecanisme rendant compte de l'influence des genes sur les differences de directions de fuite des talitres est alors propose, prenant comme base une possible polaromenotaxie. La seconde partie, plus theorique, consiste en une reflexion dans le domaine de la biologie evolutive, sur le maintien d'une telle influence genetique au cours de l'evolution. L'accent est mis sur l'importance des contraintes genetiques dans les processus evolutifs
