Corsican marine aquaculture is one of the highest contributors fish production in France, which may result environmental perturbations caused by organic matter (OM) accumulation under farms and impacting natural communities. This study aimed to (1) characterise conditions at two different farms, (2) monitor response benthic foraminiferal species this activity, (3) assess accuracy existing bioti...

The Rotimer, a rotifer-specific biopolymer, is an exogenic bioactive exudate secreted by different monogonant species (e.g. Euchlanis dilatata or Lecane bulla). production of this viscoelastic biomolecule induced micro-particles, thereby forming special Rotimer-Inductor Conglomerate (RIC) in web format. In case, the water insoluble Carmine crystals, filtered to size (max. diameter was 50 µm), f...

Metazoan parasites of the minor stardrum, Stellifer minor (Tschudi) (Osteichthyes, Sciaenidae), caught by artisanal fishery on Chorrillos, Lima, Peru. A research on some community components of parasitefauna of 105 specimens of Stellifer minor (Tschudi, 1844) collected from Chorrillos Fishmarket, Lima, Peru, between May and October 1998 and necropsied to study parasite communities was conducted...

Abstract A greater understanding of biodiversity and the roles various species involved in Southern Ocean pelagic food webs is needed to predict hypothesize about responses future scenarios relation climate changes. The aim this paper was describe for first time composition, relative abundance, spatial distribution with water masses amphipods Terra Nova Bay, Ross Sea, based on stratified sampli...

2014 marked the sixth and most widespread mass bleaching event reported in the Northwestern Hawaiian Islands, home to the Papahānaumokuākea Marine National Monument (PMNM), the world's second largest marine reserve. This event was associated with an unusual basin-scale warming in the North Pacific Ocean, with an unprecedented peak intensity of around 20°C-weeks of cumulative heat stress at Lisi...

To determine the composition and abundance of zooplankton assemblages in Eğirdir Lake-Turkey, monthly surveys were conducted from January to December 2010 at four stations. A total of 65 major zooplankton species were identified. Rotifera was the most abundant taxon dominated mainly by the species Polyarthra dolichoptera and Keratella cochlearis. Rotifers were recorded at the maximum abundance ...

Sedentary, shallow-water marine invertebrates have many ways to cope with environmental stress. In responding to salinity changes, for example, marine bivalves and gastropods typically use their shells as barriers: bivalves simply close their valves (Shumway 1977; Djangmah et al. 1979), while some gastropods can adhere tightly to a hard substrate (Fretter 1984; Chaparro et al. 2011), thereby is...

The genus Agelas comprises a group of tropical and subtropical reef sponges that contains large, long-lived, often brightly colored and conspicuous species, distributed throughout the tropica l western Atlantic, temperate northern Atlantic (Mediterranean Sea), and western and central Indo-Pacific Realms. Among tropical sponge genera, Agelas is one with similar species richness in the Greater Ca...

In Andean lakes a distinctive assemblage of large mixotrophic ciliates (>80 μm), dominated by the peritrich Ophrydium naumanni Pejler and the heterotrich Stentor araucanus Foissner & Wölfl, has been previously reported (Wölfl, 1995; Modenutti, 1997; Queimaliños et al., 1999; Modenutti et al., 2000). These two species have been found only in large, deep ultra-oligotrophic lakes (area >5 km2, Zma...
