Ontogenetic habitat shift of an herbivorous crab: a chemically mediated defense mechanism?
(UNIV VALPARAISO, 2011)
A network-based approach to the analysis of ontogenetic diet shifts: An example with an endangered, small-sized fish
(Elsevier, 2011)
Many organisms exhibit ontogenetic shifts in their diet and habitat use, which often exert a large
influence on the structure and expected dynamics of food webs and ecological communities.
Nevertheless, reliable methods ...
Trophic inferences of the gray triggerfish Balistes capriscus based on stable isotopes analyses, in the Colombian Caribbean
The demersal fish are a commercial resource of small-scale fisheries of northern Colombian Caribbean. Balistes capriscus is frequently and important in fishing landings, but this species has not economic value and its ...
Ecology of the spider crab Libinia ferreirae (Brachyura: Majoidea): ontogenetic shifts in habitat use
(Springer, 2017-07-01)
We described the ecology of the spider crab Libinia ferreirae testing the habitat segregation during the ontogenetic shifts. Collections were performed monthly by trawling along the coastal area of Cananeia, Sao Paulo State ...
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 ...
Feeding habits and habitat selectivity of the shortnose guitarfish, Zapteryx brevirostris (Chondrichthyes, Rhinobatidae), off north Argentina and Uruguay
(Taylor & Francis As, 2011-04)
Dietary shifts with predator’s size, maturity stage and season and bottom type selection of Zapteryx brevirostris were evaluated, using generalized linear models. In terms of index of relative importance, the most important ...
Shade tolerance within the context of the successional process in tropical rain forests
(2019)
Abstract: Shade tolerance (the capacity to survive and grow over long periods under shade) is a key component of plant fitness and the foundation of current theories of forest succession in tropical rain forests. It serves ...
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 ...
