Eco-evolutionary feedback as a driver of periodic state shifts in tri-trophic food chains
Eco-evolutionary feedback can result in periodic shifts with long intervals between alternative community states. Simulations using a food chain...

Historic trophic decline in New England’s coastal marine ecosystem
Overfishing is a worldwide occurrence that simplifies marine food webs, changes trophic patterns, and alters community structure, affecting not only...

Habitat loss causes long extinction transients in small trophic chains
Transients in ecology are extremely important since they determine how equilibria are approached. The debate on the dynamic stability of ecosystems...

Higher reproductive performance of a piscivorous avian predator feeding on lower trophic-level diets on ponds with shorter food chains
Variation in food-chain length may influence a predator’s trophic position. In aquatic food webs, the energy value of prey typically increases with...

Trophic dynamics of two omnivorous shrimps in the middle Paraná River
Research on how hydrological regimes affect the attributes of floodplain systems is fundamental to understanding ecosystem functioning. The shrimps Mac...

Distinct trophic ecologies of zooplankton size classes are maintained throughout the seasonal cycle
Marine food webs are strongly size-structured and size-based analysis of communities is a useful approach to evaluate food webs in a way that can be...

Shark mandible evolution reveals patterns of trophic and habitat-mediated diversification
Environmental controls of species diversity represent a central research focus in evolutionary biology. In the marine realm, sharks are widely...

Trophic Transfer Efficiency in Lakes
Trophic transfer efficiency (TTE) is usually calculated as the ratio of production rates between two consecutive trophic levels. Although seemingly...

Archaeological sharks: changes in the trophic ecology between late Holocene and modern shark communities in South Brazil
Sharks are essential components of marine communities, and their removal might simplify ecosystems and lead to unpredictable and detrimental effects...

Trophic interactions between native newts and introduced mosquitofish suggest invaded ponds may act as demographic sinks
Alien predator introduction is a global threat to amphibians. Yet, there is a lack of in situ studies of trophic interactions between alien predators...

Trophic niche of the invasive Cherax quadricarinatus and extent of competition with native shrimps in insular freshwater food webs
Quantifying the trophic niche of non-native species is a valuable way to measure both their invasion success and putative impacts on recipient food...

Conifers and non-native tree species shift trophic niches of generalist arthropod predators in Central European beech forests
BackgroundFunctional diversity is vital for forest ecosystem resilience in times of climate-induced forest diebacks. Admixing drought resistant...

Trophic niche partitioning of Mekong giant catfish Pangasianodon gigas in a tropical reservoir: evidence from stable isotope and fatty acid analyses
Large-bodied animals, such as the Mekong giant catfish ( Pangasianodon gigas ), may modify prey communities and affect their potential competitors for...

Seasonal variations of the trophic niche width of Hemimysis anomala in Lake Geneva
The trophic niche of invasive species can vary overtime because of different processes related to ecological opportunity and invader activity that...

Trophic Niche Metrics Reveal Long-Term Shift in Florida Bay Food Webs
Seagrass beds in Florida Bay are home to many ecologically and economically important species. Anthropogenic press perturbation via alterations in...

Trophic connectivity between the terrestrial and marine ecosystems of Malpelo Island, Colombia, evaluated through stable isotope analysis
The trophic dynamics of islands with low terrestrial primary productivity often depend on marine allochthonous inputs from nearby donor habitats. For...

Trophic structure of fish assemblages from oligotrophic tropical rivers: evidence of growing assimilation of autochthonous primary producers with the increase in river dimensions
In this study, we analyzed the trophic structure and carbon sources supporting fish assemblages of five low-productivity rivers with different...

Trophic Transfer of PUFAs—‘Vital Ones Reach Top Predators’
Central of the trophic transfer is its efficiency, the ratio between production of one trophic level and that of the previous one. Long-chain...

Stable isotopes, morphology, and body condition metrics suggest similarity in the trophic level and diversity in the carbon sources of freshwater and early marine diets of Chinook salmon
For anadromous fish entering the marine environment, we expect the probability of avoiding predation and starvation to increase with the quality...
