Morphometric and parasitological evidence for ontogenetic and geographical dietary shifts in intertidal fishes
(UNIVERSITY OF MIAMI PRESS, 2002)
Ontogenetic changes in feeding habits of northern elephant seals revealed by δ15N and δ13C analysis of growth layers in teeth
(Marine Ecology Progress Series, 2012)
Stable isotope analysis is useful for examining the feeding strategies of mammals. Isotopes in the annual deposition growth layers of dentine in teeth permit assessment of ontogenetic dietary shifts in individuals, because ...
Ontogenetic diet shifts and food partitioning between two small sympatric skates (Chondrichthyes, Rajidae) in the Southwestern Atlantic
(Csiro Publishing, 2012-11)
Knowing how sympatric species partition their resources is very important for understanding the mechanisms that influence marine community structure. We test the hypothesis of resource partitioning between two sympatric, ...
Fossil snake preserving three trophic levels and evidence for an ontogenetic dietary shift
(Springer, 2016-08)
We report a fossil snake from the middle Eocene (48 Ma) Messel Pit, in whose stomach is a lizard, in whose stomach is an insect. This is the second known vertebrate fossil containing direct evidence of three trophic levels. ...
Geographical and intrapopulation variation in the diet of a threatened marine predator, Pontoporia blainvillei (Cetacea)
(Wiley-Blackwell, 2018-01-01)
Understanding diet variation is a major concern when developing conservation guidelines for threatened species, especially for marine predators whose prey availability can be reduced by commercial fisheries. Diet can vary ...
Feeding ecology of the beach silverside Atherinella blackburni (Atherinopsidae) in a tropical sandy beach, Southeastern Brazil
(Inst Oceanografico, Univ Sao Paulo, 2017-07-01)
The feeding ecology of the beach silverside (Atherinella blackburni) in the surf zone of a tropical sand beach, located in the southeastern Brazil, was accessed through the gut content analysis of 198 fish. Factors such ...
Application of otolith morphometry for the study of ontogenetic variations of Odontesthes argentinensis
(Springer, 2019-08)
The study of otolith morphometry is a tool widely used in numerous studies of fish populations (fish stocks, taxonomic, ecological, ontogeny, among others). The aim of this study was to detect ontogenetic variations in the ...
