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.

Contrasting evidence of phylogenetic trophic niche conservatism in mammals worldwide [PDF]
, 2017 Aim Phylogenetic niche conservatism (PNC), a pattern of closely related species retaining ancestral niche-related traits over evolutionary time, is well documented for abiotic (Grinellian) dimensions of the ecological niche.

Macrophytes shape trophic niche variation among generalist fishes
PLOS ONE, 2017 Generalist species commonly have a fundamental role in ecosystems as they can integrate spatially distinct habitats and food-web compartments, as well as control the composition, abundance and behavior of organisms at different trophic levels. Generalist populations typically consist of specialized individuals, but the potential for and hence degree of

Solving the woolly mammoth conundrum: amino acid 15N-enrichment suggests a distinct forage or habitat [PDF]
, 2015 Understanding woolly mammoth ecology is key to understanding Pleistocene community dynamics and evaluating the roles of human hunting and climate change in late Quaternary megafaunal extinctions. Previous isotopic studies of mammoths’ diet and physiology

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