The occurrence of changes in the trophic level (TL) of sharks with growth has not been quantified until now. Here length-related changes on Squatina guggenheim Marini trophic level were determined, and shifts in type, size and trophic level of its prey were analysed. Sampling took place during five bottom trawl surveys conducted in the Argentine–Uruguayan Common Fishing Zone during spring (December/1995, October/1997) and fall (March/1997, March–April/1998, May–June/1998), using an Engel bottom… Expand

Long-term changes in the spiny dogfish (Squalus acanthias) trophic role in the southwestern Atlantic
TLDR
A comprehensive dataset on the diet of Squalus acanthias in the southwestern Atlantic Ocean was used to test the hypothesis that fishery has caused a decrease in the trophic level of this species (fishing down process), and generalized linear models were used to evaluate the support in the data for five explanatory variables.

Trophic ecology of twoblotch ponyfish Nuchequula blochii in Kendari Bay , Southeast Sulawesi , Indonesia
Trophic ecology can be used to determine feeding strategy and indirect energy flux within a fish community, and also explains the trophic interaction between different fish species in a food web.Expand
Feeding together: a global diet analysis of twenty-three species of chondrichthyes on a feeding ground area
TLDR
Trophic partitioning and ontogenetic diet shifts may act synergistically, favoring the coexistence of at least 23 species of chondrichthyes at all stages of their life histories, limiting the direct competition for food. Expand
Trophic ecology of yellownose skate Zearaja chilensis, a top predator in the south-western Atlantic Ocean.
The diet and trophic level (TL ) of the yellownose skate Zearaja chilensis in the south-western Atlantic Ocean (35°-54° S), and how these varied in relation to body size, sex, maturity stage, depthExpand
The feeding ecology of Mustelus schmitti in the southwestern Atlantic: geographic variations and dietary shifts
TLDR
The feeding ecology of Mustelus schmitti was studied based on analysis of stomach contents of 525 specimens collected from three research cruises carried out during October 2008 to March 2009 indicating an intense and continuous feeding activity of the species. Expand
Spatio-temporal and ontogenetic changes in the diet of the Argentine hake Merluccius hubbsi
TLDR
The diet and the trophic level of the Argentine hake Merluccius hubbsi was investigated in the south-west Atlantic Ocean and revealed ontogenetic dietary changes associated with size, from zooplankton crustaceans during early life stages to fish and cephalopods. Expand
Diet shifts of Rhizoprionodon terraenovae from the southern Gulf of Mexico: possible scenario by temperature changes
TLDR
Diet for R. terraenovae is associated with SST, allowing for the development of possible scenarios related to climatic phenomena like climate change. Expand
Role of body size and temporal hydrology in the dietary shifts of shortjaw tapertail anchovy Coilia brachygnathus (Actinopterygii, Engraulidae) in a large floodplain lake
TLDR
Significant differences in δ13C values were observed among larger anchovies between seasons, indicating a temporal dietary shift, and C. brachygnathus exhibited higher δ15N values during the wet season because the food items were 15N-enriched. Expand
Partitioning of food resources by four abundant, co-occurring elasmobranch species: relationships between diet and both body size and season
TLDR
Testing statistically the hypothesis that the diets of four abundant and co-occurring elasmobranch species differ and change with body size and season and the extent of any differences found any differences, to ascertain their potential for reducing competition for food resources. Expand
Dietary ecology and trophic level of adults of the Chilean angel shark Squatina armata Philippi 1887 in the Central-Eastern Pacific Ocean
TLDR
The results showed that S. armata feeds on the same prey items all year round and it does not display dietary changes, which indicates that this shark species is a selective predator with functions of a mesopredator. Expand

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
Trophic ecology of Squatina guggenheim on the continental shelf off Uruguay and northern Argentina
TLDR
An angel shark endemic to the south-west Atlantic, Squatina guggenheim, was caught during five research cruises carried out in the Argentine-Uruguayan Common Fishing Zone at depths of 3·5–266 m. Expand
Diet, feeding habits, and diel feeding chronology of the bonnethead shark, Sphyrna tiburo, in southwest Florida
TLDR
Results suggest that S. tiburo is a specialist that undergoes dietary shifts depending on season and habitat, and the shortcomings of the most commonly used approach and the limited value of considering only stomach contents weight to investigate diel feeding chronology are revealed. Expand
Small pelagics in upwelling systems: patterns of interaction and structural changes in "wasp-waist" ecosystems
TLDR
It is doubtful that pelagic fisheries will continue to increase without major disruptions to ecosystems, and predation on zooplankton by the jack mackerel in the South Pacific provides an example of the alteration of matter fluxes in trophic webs caused by fishery removals. Expand
Standardized diet compositions and trophic levels of sharks
TLDR
Standardized diet compositions and trophic levels calculated for a suite of species found sharks as a group are tertiary consumers, and mean TL for sharks was significantly higher than for seabirds but not for marine mammals. Expand
Feeding habits and trophic levels of Mediterranean fish
TLDR
Acrossspecies, TROPH values increased asymptotically with maximum reported body length and the within- andamong-species asymPTotic relationships betweenTROPH and body length are discussed within the framework of foraging behavior and preyselection theory. Expand
Reproduction, abundance and feeding habits of the broadnose sevengill shark Notorynchus cepedianus in north Patagonia, Argentina
TLDR
Anegada Bay may be an important area for conservation of N. cepedianus in the SW Atlantic given the high abundance of juveniles and subadults, and the location of the fishing hook in sharks is consistent with previous observations. Expand
Reproduction of the angular angel shark (Squatina guggenheim): geographic differences, reproductive cycle, and sexual dimorphism
TLDR
In both sexes, individuals from ER attained a larger maximum total length (L T) and a heavier weight at a given length than those from LP (La Plata River estuary), suggesting a population with low productivity. Expand
Comparisons between the influence of habitat type, season and body size on the dietary compositions of fish species in nearshore marine waters
TLDR
The seasonal and habitat variations recorded in the diets of the fish species in this study imply that these species are able to feed opportunistically, a characteristic that would be of particular value to fish that live in nearshore waters where the relative abundance of the different prey types varies with habitat type and season.

TLDR
Young-of-the-year rock bass and smallmouth bass were studied in 1977 along the west shore of Grand Island in the upper Niagara River, New York and indicated that smallmouthbass preferred a rocky substrate whereas rock bass preferred a heavily vegetated substrate. Expand
