Isotopic niche partitioning in a multi-species assemblage
Multi-species assemblages can help identify key resources in their habitat by evaluating how they are partitioning their resources. Here we used the...
-
Human habitat modification, not apex scavenger decline, drives isotopic niche variation in a carnivore community
Top carnivores can influence the structure of ecological communities, primarily through competition and predation; however, communities are also...
-
Ontogenetic variation in isotopic niche positions of aquatic consumers in boreal lakes
We used an extensive multispecies dataset to examine how C and N stable isotope ratios (δ 13 C and δ 15 N) of aquatic consumers varied with body size in...
-
Isotopic diversity and niche patterns reveal contrasting resource use among co-occurring non-native fishes within a flow-altered African river system
Classic and contemporary trophic ecology-based studies have shown that most non-native freshwater fish species (NNS) that integrate into novel...
-
Seasonal variability in the isotopic niche of the invasive channel catfish Ictalurus punctatus in Japan
The global threat posed by non-native species to biodiversity and freshwater ecosystems necessitates understanding their ecological impacts. The...

Individuals matter more than replicates: distribution of sampling effort in isotopic niche estimation
The number of individuals to be sampled is a key element in the sampling design of any study as it directly affects the estimations and inferences...
-
Comparison of resource use by invasive Black Carp and native fishes using isotopic niche analysis reveals spatial variation in potential competition
Invasive Black Carp ( Mylopharyngodon piceus ) pose a dual threat to North American freshwater ecosystems through consumption of threatened and...

Isotopic niche of New Jersey terrapins suggests intraspecific resource partitioning, and little variability following a major hurricane
Diamondback terrapins ( Malaclemys terrapin ) are sexually dimorphic generalist turtles that inhabit salt marshes and estuaries along the Atlantic and...
-
Isotopic niche partitioning and individual specialization in an Arctic raptor guild
Intra- and inter-specific resource partitioning within predator communities is a fundamental component of trophic ecology, and one proposed mechanism...
-
Breeding stage and tissue isotopic consistency suggests colony-level flexibility in niche breadth of an Arctic marine bird
Organisms must overcome environmental limitations to optimize their investment in life history stages to maximize fitness. Human-induced climate...

Dietary niche overlap in an understudied Mustelidae community in the subboreal forests of western North America: does body size differentiate dietary niche?
Understanding the many ways closely related species are adapted to coexist is fundamental for maintaining biologically diverse ecological...
-
Trophic niche diversity and redundancy across trophic positions in a subtropical river fish assemblage
Understanding consumer–resource interactions is essential for understanding the trophic dynamics of species-rich fish communities. Woodland et al....
-
Flexible foraging strategies in a highly pelagic seabird revealed by seasonal isotopic niche variation
Flexibility in foraging strategy is an important mechanism by which seabirds cope with spatiotemporal heterogeneity in food availability and the...
-
Effect of human impact on coral reef herbivorous fish niche
The lower abundance, biomass, and homogenization of sizes of herbivorous fish caused by overfishing may lead to a disproportionate loss of functions....
-
Diet, isotopic niche, and spatial distribution of the white-headed petrel (Pterodroma lessonii) at Kerguelen Islands
The subantarctic white-headed petrel is unique amongst Procellariidae by its biennial breeding frequency. Its food and feeding ecology is poorly...
-
Impacts of zebra mussels (Dreissena polymorpha) on isotopic niche size and niche overlap among fish species in a mesotrophic lake
Zebra mussels ( Dreissena polymorpha ) filter feed phytoplankton and reduce available pelagic energy, potentially driving fish to use littoral energy...
-
Niche partitioning and seasonality may mediate coexistence of piranha species in Amazonian floodplain lakes
Unraveling factors that enable the coexistence of species occupying similar niches is a challenge in Ecology. In the Amazon basin, several piranha...

Niche partitioning among odontocetes in a marine biogeographic transition zone of the western South Atlantic Ocean
Toothed cetaceans represent a diverse and important component in poorly studied pelagic food webs. We used the variation in δ 13 C and δ 15 N values in...
-
Niche partitioning and individual specialisation in resources and space use of sympatric fur seals at their range margin
Ecological theory predicts niche partitioning between high-level predators living in sympatry as a mechanism to minimise the selective pressure of...
-
Human-modified landscapes narrow the isotopic niche of neotropical birds
Deforestation and habitat loss resulting from land use changes are some of the utmost anthropogenic impacts that threaten tropical birds in...
