ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Abstract Substantial individual variation in diet and foraging strategies can exist within populations. These differences can enhance individual foraging efficiency, reduce intraspecific competition, and provide fitness advantages that increase the resilience of a population.

Krill fisheries: Development, management and ecosystem implications
There are currently at least six commercial fisheries harvesting six different species of euphausiid, or krill: Antarctic krill (Euphausia superba), fished in the Antarctic; North Pacific krill (Euphausia pacifica), fished off Japan and off western ...

Abstract During foraging activity, baleen whales are generally dependent on the occurrence of dense prey patches. These are largely influenced by the interaction between ocean currents and the vertical distribution of individual prey. Identifying the spatio‐temporal dynamics of the areas where prey form dense aggregations, at submeso scale (~ 10 km ...

Multifrequency acoustic target strength of Northern krill [PDF]
Although this thesis is a dissertation based on articles, an exhaustive overview on the main issues involved is also presented *. This is due to the necessity to summarize the numerous aspects of the problem, as well as the recent works on specific ...

Whale recovery and the emerging human-wildlife conflict over Antarctic krill
The Southern Ocean ecosystem has undergone extensive changes in the past two centuries driven by industrial sealing and whaling, climate change and commercial fishing.

Acoustic evidence for topographic blocking on a steep submarine canyon wall
Abstract Diel vertical migration (DVM) is the largest mass‐movement of animals on Earth, with profound ecological and biogeochemical consequences. DVM has mostly been studied in the open ocean; however, at steep slopes, pelagic animals including vertical migrators must contend with the seafloor, emphasizing the importance of understanding DVM in these ...

Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...
