摘要:
of bird feathers to quantify trophic positions, and we estimated population trophic niche width using Bayesian standardized ellipse area. 3. Paradoxorni
Data from: Limited trophic partitioning among sympatric delphinids off a tropical oceanic atoll

摘要:
community structure and dynamics. In this study, we used stable isotope analysis of skin biopsies to compare the isotopic, and thus, trophic niches of three sympatric
Data from: Trophic consistency of supraspecific taxa in belowground invertebrate communities: comparison across lineages and taxonomic ranks

Arthropoda niche conservatism phylogenetic signal soil food web taxonomic sufficiency taxonomic resolution trophic niche stable isotopes
摘要:
when measurements of trophic niches of local populations are not feasible. Supraspecific taxa are meaningful as trophic nodes in food-web studies, but the consistency
Data from: Patterns of trophic niche divergence between invasive and native fishes in wild communities are predictable from mesocosm studies

关键词:
trophic niche width invasive species freshwater ecosystems stable isotope analysis trophic relationships
摘要:
ties in larger ponds were consistent with those in the mesocosm experiments. Their invasion resulted in divergence in trophic niches, partly due to their reduced
Data from: Seasonal change in trophic niche of adfluvial arctic grayling (Thymallus arcticus) and coexisting fishes in a high-elevation lake system

Recent;stable isotopes;hypoxia;trophic niche;Season;Arctic grayling;Holocene;Thymallus arcticus;non-native species
摘要:
of fish taxa in fall and spring to assess both short- (within season) and long-term (between season) changes in trophic niches. We incorporated these data
Data from: Realized trophic niche driven by apparent competition: an example with marsupials
负责人:
Kuhnen, Vanessa Villanova

摘要:
share similar resources, we would expect the absence of top predators to reflect in changes on prey realized trophic niches. To test our hypothesis
Data from: Spider webs, stable isotopes and molecular gut content analysis: multiple lines of evidence support trophic niche

摘要:
clades, one web building and the other actively hunting, which co-occur in wet forest on East Maui. We hypothesize that trophic niches differ signific
Data from: Are species’ responses to global change predicted by past niche evolution?

摘要:
of demographic trends between 1970 and 2000 are available, along with a species-level phylogeny and data on climatic, habitat, and trophic niches. We found that species
Data from: Unravelling the role of allochthonous aquatic resources to food web structure in a tropical riparian forest

ecosystem boundaries food web structure flux across ecosystems
摘要:
e is known on the effects of allochthonous subsidies on food web structure and trophic niche dimensions of consumers in the tropics. 2. We excluded alloch
Data from: Predicting the ecological impacts of an alien invader: experimental approaches reveal the trophic consequences of competition

Comparative functional response Invasive species non-native predator-prey invasive species
摘要:
can result in coexisting species having constricted and diverged trophic niches, the competing species might instead increase their niche sizes to maintain
