Summary: This study investigates resource partitioning among prey fish species in Lake Ontario by using trophic tracers, pollutants, and bioenergetic modelling. The results demonstrate that the trophic relationships among species can be confirmed by carbon and nitrogen isotopes, and the PCBs concentration is highly correlated with temperature occupancy predictions. The three-dimensional niche modelling suggests that species behavioural thermoregulation is likely the direct cause of ecological tracer assimilation.

Summary: It was found in the study that in environments with limited groundwater resources, there is a strong correlation between the morphological characteristics and trophic habits of Niphargus amphipods. Species with larger and more powerful gnathopods tend to have higher trophic positions, indicating a close relationship between morphology and trophic habits.

Summary: This study focused on the lactation and foraging behavior of Weddell seals in East Antarctica. The results showed that the seals primarily fed on benthic prey in specific spatial locations. Prey capture attempts mainly occurred on the seafloor, and the prey often reacted by escaping or leaving the seafloor. The seals displayed opportunistic foraging behavior by continuously scanning the area during the approach phase.

Summary: The accelerating loss and degradation of tropical forests necessitates a better understanding of the conservation value of remaining forests. By analyzing the trophic ecology of insectivorous bats in the tropical forests of Sabah, Borneo, this study demonstrates that changes in trophic complexity can be a more reliable indicator of habitat degradation than traditional community descriptors.

Summary: The input of pollutants from human activities deteriorates the surface water quality in Chaohu Lake Basin. The hydrochemical characteristics and stable isotope composition of lake water and inflow river water were analyzed to understand the influence of human activities. The results show that the water chemistry and ions in surface water are affected by both rock weathering and human activities. The stable isotope analysis indicates that surface water mainly originates from precipitation. Pollution indicators suggest severe pollution in certain rivers due to sewage and agricultural fertilizers.

Summary: The study used next-generation sequencing and stable isotope analysis to investigate the diet of house mice on Sand Island. The results showed that the mice mainly consumed arthropods and also fed on detrital-feeding arthropods in and around seabird carcasses. Most of the arthropods and plants consumed by the mice were non-native. The study also found that the mouse diet composition varied among habitat types but remained stable throughout the year.

Summary: The study analyzed the diet and trophic relationships of 4 sympatric hammerhead shark species, revealing that their trophic niches tend to be more similar within species than among them, indicating potential competitive interactions between conspecifics. Subadults of S. lewini could be considered top predators, with significant implications for the structure and function of marine food webs.

Summary: Foraging decisions have a significant impact on the structure of food webs, as a behavioral shift in a single species can potentially modify resource-flow dynamics of entire ecosystems. Through a field experiment, this study found that semi-arboreal brown anole lizards drastically increased their perch height and reduced consumption of marine-derived food resources in the presence of predatory ground-dwelling curly-tailed lizards. This shift in foraging niche altered the dynamics of resource flow between the oceanic and terrestrial ecosystems, and persisted in the diets of the first-generation offspring. Additionally, female lizards with more risk-taking behaviors consumed more marine prey when predators were present on the islands.

Summary: This study investigated the foraging behavior, habitat use, ecological niche, and diet of the Endangered Bermuda petrel. The study found that petrels traveled over a vast area of the western North Atlantic while foraging, but reduced their range and time at sea during the early chick-rearing phase. Foraging locations were influenced by environmental variables, including oceanographic features, distance to the colony, and wind speed. The petrels' diet consisted of a diverse range of meso-bathypelagic fishes and cephalopods.
