Resumen
Present communication reports the physico-chemical and biological quality of seawater and status of benthos of a highly industrialized shore of the north-western coastline of India. The coastal area considered for the present study, encircled by a variety of industries, was divided into two sampling sites and monitored for two consecutive years. Results of the water quality suggest that the obtained values of the physical and chemical parameters of seawater were comparable with data reported earlier. However, data obtained in the biological parameters of the seawater showed a declining trend.

Resumen
The influence of Eucalyptus plantations on the structure and composition of macroinvertebrate communities associated with the aquatic fern Salvinia auriculata Aublet were investigated in a high altitude lake bordered by either secondary Atlantic forest or Eucalyptus plantations. Comparisons of the diversity of Chironomidae (Diptera, Insecta) larvae in the littoral zone between these two vegetation types showed higher diversity of larvae in waters bordered by Eucalyptus. The results demonstrated that the predominance of carnivorous taxa among the macroinvertebrate fauna appears to be the major

Resumen
Most studies of pond animals are undertaken during the daytime, despite evidence that many pond organisms demonstrate marked nocturnal changes in behaviour. Nocturnal studies of animals in fishless ponds are particularly rare, probably because diel changes in aquatic animal behaviour are often found to be a response to visual predation by fish. We used non-metric multidimensional scaling (MDS) and analysis of similarity (ANOSIM) to detect patterns of similarity in the community composition of macroinvertebrates and amphibians in samples taken from vegetated and unvegetated areas during the day

Resumen
Ports of big coastal cities are exposed to exotic species as a consequence of shipping traffic. As the Port of Recife receives an annual average of 491 ships from other regions of Brazil and from all over the world, this work was aimed at knowing which marine animals were passively transported on such vessels hulls, in order to map and monitor new bioinvasions in the area. Thus, 32 vessels of several origins were investigated between November 2005 and March 2006, samples were taken and the macrofauna identified. Sixty species of associated animals were identified, consisting of 28 sessile spec

Resumen
Little is known about colonization of remote island coasts by marine invertebrates, other than corals. The structure of hard substrata assemblages was investigated across Ascension Island's littoral zone in comparison with other sites. Arrays of acrylic panels were deployed at two sites for 2 years at Ascension Island to measure subtidal recruitment. Colonization of panels at Ascension I. was low, though space occupation, abundance and richness varied considerably. After ~1 and 2 years Ascension panels were <17 and <37% covered by fauna and each had <22 recruits and 54 recruits (per 1

Resumen
Anthropogenic reductions in braiding, meandering, and snag abundance have diminished habitat heterogeneity of regulated rivers, factors directly influencing island formation, retentive capacity of the ecosystem, and community diversity. Habitat heterogeneity associated with riverine islands should, therefore, be of paramount importance to the ecosystem and may require special management protection. To understand the influence of these alluvial formations on riverine benthos, macroinvertebrate assemblages were sampled near three islands in the Ohio River above Louisville, Kentucky, USA. Benthos

Resumen
ABSTRACT A contiguous region of tidal flats about 448 km (280 miles) long and up to 21 km (13 miles) wide extends along the North Sea coasts of the Federal Republic of Germany, The Netherlands, and Denmark. This region is called the Wadden Sea. It is of enormous value as a cleansing site for the North Sea water, as a nursery for young fishes, and as a feeding grounds for nearly all Palearctic species of wading birds and waterfowl. The proximity of important shipping routes and ports is a permanent threat, especially to the German part of the region, which became a national park in 1986. The re

Resumen
We studied the habitat structure (macrofaunal assemblages and bottom types) and zonation patterns of 29 unvegetated shoreline strands along the 900-km coast of Catalonia (NW Mediterranean Sea). Organisms were sampled with grabs, pitfall traps, sticky traps, clam nets and spades to ensure capture of the different proportions of macrofaunal assemblages from the supra-, medio- and infralittoral levels. We collected 211 taxa: 194 animals and 17 algae. The most abundant and dominant organisms collected with van Veen grabs were Nematoda, Oligochaeta and Collembola at the supralittoral level; the pol

Resumen
Discriminer l'influence des activités humaines de celle des processus naturels sur les changements environnementaux récents est un enjeu scientifique important. Dans ce but, les mollusques et les foraminifères fossiles des Pertuis Charentais (ouest de la France) ainsi que les sédiments déposés pendant l'Holocène dont ils sont issus ont été étudiés. L'objet d'étude central est un drapage vaseux qui constitue une grande partie du comblement sédimentaire terminal des Pertuis. Les résultats obtenus montrent qu'il est composé de sédiments fins d'origine continentale déposés à partir de 1400 AD. Il

Depuis 2008, la mortalité des naissains d'huîtres Pacifique Crassostrea gigas est principalement liée au virus de l’ostreid herpesvirus 1 µvariant (OsHV-1 µVar). Les paramètres environnementaux favorisant la persistance et la diffusion du virus pourraient jouer sur sa dynamique de propagation. Les objectifs de cette thèse étaient d’étudier in situ les interactions entre les naissains d’huîtres et leur environnement benthique lors d’un épisode de surmortalité.

Resumen
This thesis is composed of three separate chapters, two of which are published, an introductory and a concluding chapter. The main question that led to the development of the studies presented in the thesis is the following: is it possible to compare behavioural and ecological studies at a large geographical scale in the context of the ecosystems of sandy beaches under environmental changes? After the first introductory chapter, in the second chapter I present a review of studies in different (geographically distant) localities affected by similar distal and proximate drivers of climate change
