Summary: This study analyzed the foraging behavior of shy albatross from Albatross Island. The results showed a consistent foraging area for the population, with individuals utilizing both the shelf break and the Bass Strait. There was also evidence of individual consistency to geographic locations. Age and sex did not explain the between-individual variation in foraging behavior.

Summary: Juvenile grey-headed albatrosses from South Georgia dispersed to the northeast, overlapping with a bycatch hotspot for grey-headed albatrosses reported by the Japanese pelagic longline fleet in the southeast Atlantic Ocean. The majority of birds caught in this area are likely juveniles from South Georgia, indicating a key factor in the sustained population decline. This study emphasizes the urgent need to understand the 'lost years' of marine megafauna for targeted conservation efforts.

Summary: The study found that using tori lines significantly reduced the likelihood of albatross attempting to contact or actually contacting baited hooks. While albatross captures were also less likely in sets with tori lines, there were not enough captures to draw strong conclusions. Offal discharge during setting was associated with higher seabird interactions, but further investigation is needed to determine the efficacy of this mitigation measure.

Summary: Albatrosses attend fishing boats to feed on fishing discards but are often at risk of accidental bycatch. Populations and sexes differ in their overlap with fisheries due to differences in habitat use, impacting encounter rate of fisheries. Different habitat specialization should be considered for future assessments of risk of bycatch.

Summary: Removal of target catch from longlines by marine mammals, known as depredation, is a global issue creating animal welfare, socioeconomic, and management concerns. Killer whales are a key species of concern due to their global presence and ability to remove large quantities of caught fish. Current lack of understanding on whale behaviors around fishing vessels hinders complete assessment of depredation, highlighting the need for further investigation and improved monitoring methods.

Summary: The study found significant variation in the time and density that different populations of albatrosses spent attending fishing boats within their foraging ranges, with most boat attendances occurring within Economic Exclusive Zones. Fishing boat density at a large scale was a poor predictor of time spent attending fishing boats across populations.

Summary: Food availability and oceanographic conditions drive the distribution and movement of marine vertebrates, such as the Magellanic penguin. This study tracked the wintering grounds of five penguins along the southern coast of Brazil and Uruguay, and found that they remained in neritic waters near the coast, potentially due to the abundance of nutrients and their main prey, the Argentine anchovy. The study also highlights the potential conservation concerns involving the management of anchovy fisheries and the development of offshore windfarms.

Summary: The study found differences in residency and habitat use between green turtles at Pelican Banks and Wiggins Island, with tidal patterns playing a significant role in their movements and habitat preferences.

Summary: This study examined sexual segregation in habitat use of Black-browed Albatrosses during winter and found no significant differences between males and females, likely due to abundant prey in the region and moderate energy requirements during the non-breeding season.

Summary: A predator-prey interaction between the asterinid seastars Meridiastra calcar and Parvulastra exigua occurs in southeast Australia, with the latter exhibiting a fleeing response when encountering the former. The response is triggered by physical contact and chemosensory cues, influencing the distribution of Parvulastra exigua along the tidal gradient.

Summary: This study investigates the distribution, abundance, and foraging ecology of Caspian Terns during their non-breeding season in the Peel-Harvey Estuary. The study found that two areas were particularly important for terns and their foraging, with higher foraging activity in the morning.
