Trophic response to ecological conditions of habitats: Evidence from trophic variability of freshwater fish

Ecology and Evolution, 2020
To adapt to ecological and environmental conditions, species can change their ecological niche (e.g., interactions among species) and function (e.g., prey‐predation, diet competition, and habitat segregation) at the species and guild levels.

Invasive signal crayfish and native noble crayfish show trophic niche shrinkage in sympatry [PDF]

NeoBiota
Studying the coexistence of native species and invasive species with similar functional traits, habitat usage, and feeding habits is crucial for understanding the dynamics of invasion and ecological changes in the invaded ecosystem.

Trophic Dynamics and Niches of Salt Marsh Foraminifera [PDF]

American Zoologist, 1973
Energetic considerations of the growth of three species of littoral benthic foraminifera, Allogromia laticollaris, Rosalina leei , and Spiroloculina hyalina , have been made on laboratory-grown populations. Under optimum laboratory conditions A. laticollaris has the greatest intrinsic rate of increase (r = 2.533 org/day); S. hyalina (r = 1.472 org/day),

Swimming with the giant: coexistence patterns of a new redfin minnow Pseudobarbus skeltoni from a global biodiversity hot spot

Ecology and Evolution, 2016
Ecological niche theory predicts that coexistence is facilitated by resource partitioning mechanisms that are influenced by abiotic and biotic interactions.

DataSheet_1_Interspecies trophic niche differences and spatial–temporal adaptations found in Cultrinae fishes.pdf

, 2023
It has been debated whether interspecies niche differences may follow niche conservatism, whether niches are becoming specialists, whether generalists and specialists are maintained in a balance, and how the realized niche may adapt to local or temporal ...

Bioenergetics, Trophic Ecology, and Niche Separation of Tunas

, 2016
Tunas are highly specialized predators that have evolved numerous adaptations for a lifestyle that requires large amounts of energy consumption. Here we review our understanding of the bioenergetics and feeding dynamics of tunas on a global scale, with an emphasis on yellowfin, bigeye, skipjack, albacore, and Atlantic bluefin tunas.

Trophic ecology and niche overlap of two sympatric species of Rhamdia (Siluriformes, Heptapteridae) from northeast Oaxaca, Mexico [PDF]

Neotropical Biology and Conservation
The trophic ecology of fishes in the genus Rhamdia remains poorly reported. Here, we aim to describe the diet composition and infer the trophic levels, niche breadth, and niche overlap between Rhamdia guatemalensis and Rhamdia laticauda in northeast ...
