Trophic mass-balance model of a subtropical coastal lagoon, including a comparison with a stable isotope analysis of the food-web.
Stable isotopes and mass-balance trophic models (e.g., ECOPATH) are well-known and widely used approximations to describe food-web structure, but their consistency is not properly established. HereExpand
Assessing the sources of the fishing down marine food web process in the Argentinean-Uruguayan Common Fishing Zone
The temporal trend in the mean trophic level (mTL), fisheries-in-balance index (FIB), trophic categories landing (TrC) and landing profile (LP) of the exploited marine community (82 species) in theExpand
Long-term impact of incidental catches by tuna longlines: the black escolar (Lepidocybium flavobrunneum) of the southwestern Atlantic Ocean
Abstract We analyze intra and inter-annual harvesting patterns of the black escolar Lepidocybium flavobrunneum (Gempylidae), an important component of the incidental catch of the Uruguayan tuna fleetExpand
The mean trophic level of Uruguayan landings during the period 1990–2001
Abstract The worldwide increasing trend in fishing catches together with the impact of fishing on ecosystems and inefficient fishery management have led to overfishing and frequent collapse ofExpand
Changes in trophic level of Squatina guggenheim with increasing body length: relationships with type, size and trophic level of its prey
TLDR
The study revealed an increase in S. guggenheim TL with shark growth as a consequence of changes on type, size and TL of prey ingested, and Predator-length and prey-length relationship indicated a trend. Expand
The determination of maturity stages in male elasmobranchs (Chondrichthyes) using a segmented regression of clasper length on total length
TLDR
A novel statistical method for estimating the stages of maturity in male sharks and skates based on a segmented regression (SRM) that is applicable to previously collected data, easy to use, and provides a reliable tool for increasing the understanding of elasmobranch reproductive strategies is proposed.

Influence of environmental variables on the distribution of Squatina guggenheim (Chondrichthyes, Squatinidae) in the Argentine–Uruguayan Common Fishing Zone
Abstract The environmental variables affecting the spatial distribution of Squatina guggenheim Marini, 1936, an important commercial resource, are unknown. Here the influence of temperature, salinityExpand
First record of Aluterus scriptus (Monacanthidae) in Mar del Plata, Argentina
TLDR
Scrawled filefish Aluterus scriptus (55.5 cm total length) was recorded for the first time off the Argentinean coast and was correlated with warm sea surface temperatures at the time it was caught. Expand
First record of Latris lineata (Forster, 1801) in the Southwest Atlantic Ocean.
TLDR
The striped trumpeter has never been reported from the southwest Atlantic and is regarded as a southern circum-global species widely distributed in the temperate waters of Australia, New Zealand, sub-Antarctic Auckland Island and possibly across the South Pacific to the Juan Fernandez Islands and Chile. Expand
First record of Pomacanthus paru in the Río de la Plata, Argentina
The first record of an adult male of French angelfish Pomacanthus paru (total length = 295 mm; total weight = 855.3 g) in the coastal waters of Rio de la Plata mouth, Argentina is here reported. ThisExpand
