Metabolic plasticity drives mismatches in physiological traits between prey and predator
Metabolic rate, the rate of energy use, underpins key ecological traits of organisms, from development and locomotion to interaction rates between...
-
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...

Geographic and ontogenetic variation in the diet of two commonly exploited batoids (Chilean eagle ray and Pacific guitarfish) off Peru: evidence of trophic plasticity
This study provides information about the diet across geographic areas and throughout ontogeny and sex of two coastal and commercial batoid species...
-
Contrasting intra-individual variation in size-based trophic and habitat shifts for two coastal Arctic fish species
Within and among species variation in trophic and habitat shifts with body size can indicate the potential adaptive capacity of species to ecosystem...
-
It is about time: effects of thermal fluctuations resulting from climate change on trophic interactions with a focus on host–parasitoid interactions
Climate change alters many environmental parameters with strong consequences for ecological interactions, from species interactions to community...

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...

A Comparative Study of Feeding Ecology and Trophic Relationships of Bothrocara brunneum and B. zestum (Zoarcidae) from Northwest Pacific Deep-Sea Ecosystems
AbstractThe results of analysis on the feeding patterns and assessment of the trophic levels and niches in two Zoarcidae species Bothrocara brunneum ...

Trophic ontogeny of a generalist predator is conserved across space
Consumers can influence ecological patterns and processes through their trophic roles and contributions to the flow of energy through ecosystems....
-
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...

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...
-
Species-specific trophic discrimination factors can reduce the uncertainty of stable isotope analyses
Stable isotope analysis has been broadly used to study food webs, but often relies on inaccurate assumptions of trophic isotopic discriminations,...
-
Preferential cannibalism as a key stabilizing mechanism of intraguild predation systems with trophic polymorphic predators
Theory predicts intraguild predation (IGP) to be unstable despite its ubiquity in nature, prompting exploration of stabilizing mechanisms of IGP. One...

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...

Trophic Ecology of the Marine Otter (Lontra felina): Review, Quantitative Analyses and Population Implications
The marine otter, Lontra felina, is one of the top predators of the benthic communities in the southeastern Pacific coasts, from Chimbote in Peru to...
-
Trophic niches of Collembola communities change with elevation, but also with body size and life form
Climate change will likely increase habitat loss of endemic tree species and drives forest conversion in mountainous forests. Elevation gradients...

Island Tiger Snakes (Notechis scutatus) Gain a ‘Head Start’ in Life: How Both Phenotypic Plasticity and Evolution Underlie Skull Shape Differences
Repeated island colonisation by Australian tiger snakes ( Notechis scutatus ) has become a model system demonstrating how prey size on islands...
-
Occurrence and diversity of bacterioplankton in drinking water tropical reservoirs of contrasting trophic state
Bacterial communities play key roles in freshwater reservoirs, affecting their functioning and services. Understanding their occurrence in the...
-
Invasive gibel carp use vacant space and occupy lower trophic niche compared to endangered native crucian carp
The introduction of invasive species increases interspecific competition with native species, especially if the invasive fish have a similar...

Effects of plasticity and genetic divergence in phenotypic trait expression of sulfide spring fishes
Natural environments vary, and organisms cope with this variation in two general ways: local adaptation and phenotypic plasticity, although these...

Plasticity and not adaptation is the primary source of temperature-mediated variation in flowering phenology in North America
Phenology varies widely over space and time because of its sensitivity to climate. However, whether phenological variation is primarily generated by...
