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 Mediterranean Sea is one of the most exploited regions world’s oceans. Here industrial activities have determined either acute or long-term impacts on coastal marine ecosystems. In this study, we investigated macrofauna distribution and diversity, food-web functioning in a area facing an chemical plant abandoned ‘90s to assess benthic ecosystem health. This has been identified as Site Natio...
در این تحقیق جوامع ماکروبنتیک مناطق ساحلی نوشهر در جنوب دریای خزر، از اسفند ماه سال 1388 تا آبان ماه سال 1389 به صورت فصلی مورد بررسی قرار گرفتند. در مجموع 192 گرب، نمونه رسوب از 16 ایستگاه برداشت شد و برای تعیین اندازه دانه بندی، مواد آلی کل و تنوع و تراکم ماکروفونا مورد تجزیه و تحلیل قرار گرفت. نتایج حضور 4 رده جانوری و 21 گونه ماکروبنتوز را در مناطق مورد بررسی نشان داد. از نظر تنوع گونه ای، ...
A yearlong seasonal survey was carried out during 2016–2017 at 26 stations representing four tidal channels of the north-western part Gulf Gabès (Tunisia). The area studied (characterized by a maximum range 2.3 m) subjected to diverse anthropogenic pressures: from phosphate industry and its metallic pollution, unauthorized bottom trawling in shallow water (known locally as ‘Kiss’), organic poll...
The present study was conducted to examine the impact of cage aquaculture on benthic communities in coastal areas (depth 25 to 50 m) from fish farming operations located along the southeastern Black Sea (Ordu-Perşembe, Trabzon-Yomra and Rize central). Sampling was conducted seasonally from April 2007 to 2009. Sediment samples were taken using Ekman Grab (box core- 0.04 m2). Temperature, salinit...
The relationship between visuospatial attention and paw preference was investigated in domestic dogs. Visuospatial attention was evaluated using a food detection task that closely matches the so-called "cancellation" task used in human studies. Paw preference was estimated by quantifying the dog's use of forepaws to hold a puzzle feeder device (namely the "Kong") while eating its content. Resul...
