TL;DR: The close relationship between the juvenile bluefin δ15N values and those of suspension feeders suggests that nektonic crustaceans or zooplankton may contribute significantly to the diet of bluefin tuna, a food source previously overlooked for this species in the northwest Atlantic Ocean.

TL;DR: It is found that the introduction of higher quality propagules significantly enhanced establishment across both light treatments, and increased final tiller count in the sun treatment, suggesting that propagule quality may play an important but underappreciated role in the invasion process.

TL;DR: The authors conducted incremental stable isotope analysis along the baleen plates of three North Atlantic right whales, an adult female, a juvenile male and a neonate male, showing seasonal oscillation patterns in d15N and d13C values associated with migrations between summer and winter habitats.

TL;DR: The results demonstrate that the emergence, persistence, and spread of plant invaders can be driven by different abiotic and biotic factors in the recipient habitat, providing a realistic and robust evaluation of the drivers of invasive plant success and suggesting a general need for longer-term establishment studies in invasive plant ecology.
