Gone fishing: Adélie penguin site-specific foraging tactics and breeding performance

Antarctic Science (2020)

Silvia Olmastroni Niccolò Fattorini Francesco Pezzo Silvano Focardi

Abstract The ecological drivers underlying breeding performance are expected to differ across the geographical range of seabird species, but few studies have compared trade-offs between colonies with different local conditions. During chick-rearing (2000–01), we compared the foraging trips, diet and breeding parameters of two Adélie penguin colonies in the Ross Sea, at Edmonson Point (EdPo; ~2000 breeding pairs) and Inexpressible Island (InIs; ~24 000 breeding pairs). Penguins from InIs travelled farther and performed longer feeding trips. The quantity of food brought to the nest was the same for the two colonies, but penguins from InIs brought more fish and less krill. Eggs hatched earlier at EdPo. Breeding success did not differ, but chick weight during hatching–fledging was greater at InIs. Despite worse weather conditions at InIs, the larger proportion of high-energy food brought by penguins from InIs (i.e. fish) may explain their offspring‘s better performance. In addition, the persistence of fast ice at EdPo may have led to greater energy expenditure of breeding individuals, possibly reducing chick growth. The greater intraspecific competition expected at InIs may have been reduced by longer foraging trips and/or counteracted by the more nutritious diet. Our findings reveal complex trade-offs between foraging effort and environmental constraints in determining the breeding performance of Adélie penguins.

PESTICIDE RISK ASSESSMENT IN A LAGOON ECOSYSTEM. PART II: EFFECT ASSESSMENT AND RISK CHARACTERIZATION

Environmental Toxicology and Chemistry (2003)

Sara Villa Marco Vighi Silvia Casini Silvano Focardi

Ecotoxicological risk assessment for pesticides was performed on a coastal lagoon ecosystem (Orbetello lagoon, central Italy) according to the procedure described in the European technical guidance document (TGD) on risk assessment for new and existing substances. The procedure was applied to individual chemicals and to a mixture of chemicals with the same toxicological mode of action. Biomarker studies, measuring acetylcholinesterase (AchE) activity inhibition, were conducted on Zosterisessor ophiocephalus to compare the results of theoretical risk assessment with experimental measurements of ecotoxicological stress. Value and limitations of the risk assessment procedure and its application to site-specific environmental conditions are discussed. A tool crop risk index (CRI) for assessing the overall impact of pesticide use on a crop is proposed.

Benthic Community and Sediment Types: A Structural Analysis

Marine Ecology (1983)

Eugenio Fresi María Cristina Gambi Silvano Focardi Roberto Bargagli Franco Baldi

Abstract. The distribution of the macrobenthic community, in relation to various physical and chemical characteristics of the sediment, was studied along the coast of Southern Tuscany (Central Tyrrhenian) in an area under the influence of the Ombrone River outflow. The zonation of the benthos was found to be primarily under the control of a gradient of water movement, as is reflected by variations in the sediment structure from the coast to the open sea. This correlation is somehow influenced by secondary gradients such as the degree of mixing of the sediment and the deposition of terrigenous materials along the river plume.
