Do cage fish farms promote interference in the trophic niche of wild fish in neotropical reservoir?
(2022-04-01)
Cage fish farming in hydroelectric reservoirs has been reported to promote variations in environmental conditions, which directly interfere with the foraging behavior of wild fish. We have hypothesized that the abundance ...
Feeding and reproductive patterns of Astyanax intermedius in a headwater stream of Atlantic Rainforest
(Acad Brasileira De Ciencias, 2015-12-01)
In this paper, we determined diet composition, reproductive periodicity and fecundity of Astyanax intermedius in a headwater stream of a State Park of an Atlantic rainforest. We also evaluated the influence of rainfall, ...
Ecologia trófica e ecomorfologia da ictiofauna de igarapés maranhenses (Alcântara-MA)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2011-06-07)
The trophic ecology is one of the most important aspects to understand the role of a species in the community and in the ecosystem functioning. Studies regarding the feeding of fishes coupled to the ecomorphology of a ...

Ecologia alimentar comparativa de quatro espécies simpátricas de Hypostomus em um rio do sudoeste brasileiro
(2016-07-01)
Though their broad distribution in most Brazilian rivers, scarce studies concerning ecological interactions on Hypostomus species are available. This study observes the diet, the trophic interactions and some morphological ...
Influence of substrate orientation on tadpoles' feeding efficiency
(Company Biologists Ltd, 2019-01-01)
In nature, tadpoles encounter food on substrates oriented at different angles (e.g. vertically along stems, horizontally on the bottom of the pond). We manipulated the orientation of food-covered surfaces to test how ...

Isotopic niche partitioning between two small cetacean species
(Inter-Research, 2021-02)
Commerson’s dolphin Cephalorhynchus commersonii and Peale’s dolphin Lageno - rhynchus australis live in sympatry along the southwestern South Atlantic Ocean, suggesting the existence of some degree of habitat partitioning ...
Dietary and isotopic specialization: The isotopic niche of three cinclodes ovenbirds
(2009)
By comparing the isotopic composition of tissues deposited at different times, we can identify individuals that shift diets over time and individuals with constant diets. We define an individual as an isotopic specialist ...
