TLDR
In this paper, the authors investigated the potential effect of climate change on the distribution and diversity of marine top predators and found that, based on data from electronic tags on 23 marine species, a change in core habitat range of up to 35% is possible for some species by 2100.Abstract:
Climate change scenarios predict an average sea surface temperature rise of 1–6 °C by 2100. Now, a study investigating the potential effect of these changes on the distribution and diversity of marine top predators finds that, based on data from electronic tags on 23 marine species, a change in core habitat range of up to 35% is possible for some species by 2100.read more

TL;DR: A brave new world with a wider view Researchers have long attempted to follow animals as they move through their environment, but such efforts were limited to short distances and times in species large enough to carry large batteries and transmitters, while new technologies have opened up new frontiers in animal tracking remote data collection.

TL;DR: This exercise assembled 40 experts to identify key questions in this field, focussing on marine megafauna, which include a broad range of birds, mammals, reptiles, and fish, and shows that the questions have broad applicability to other taxa, including terrestrial animals, flying insects, and swimming invertebrates.

TL;DR: A shift towards dynamic ocean management is suggested, defined as management that rapidly changes in space and time in response to changes in the ocean and its users through the integration of near real-time biological, oceanographic, social and/or economic data.

TL;DR: The authors all know that doctors make the worst patients because they always laughingly tell us so, but how do they rate at taking their own medicine?

Potential effects of sea level rise on the terrestrial habitats of endangered and endemic megafauna in the Northwestern Hawaiian Islands
TL;DR: In this article, the authors explored the potential for habitat loss in the Northwestern Hawaiian Islands (NWHI) by creating topographic models of several islands and evaluating the potential effects of sea level rise by 2100 under a range of basic passive flooding scenarios.

Range contraction in large pelagic predators

TL;DR: The results mirror patterns described for many land predators, despite considerable differences in habitat, mobility, and dispersal, and imply ecological extirpation of heavily exploited species across parts of their range.

TL;DR: In this paper, an improved version of the SEAPODYM model was used to investigate the potential impacts of global warming on tuna populations, which included an enhanced definition of habitat indices, movements, and accessibility of tuna predators to different vertically migrant and non-migrant micronekton functional groups.

Insights into the population structure of blue whales in the Eastern North Pacific from recent sightings and photographic identification
TL;DR: In this paper, the authors document 15 blue whale sightings off British Columbia and in the Gulf of Alaska made since 1997, and use identification photographs to show that whales in these areas are currently part of the California feeding population, which may represent a return to a migration pattern that has existed for earlier periods for eastern North Pacific blue whale population.

TL;DR: It is demonstrated that dynamic habitat models based on telemetry data may help to project interactions with pelagic animals relative to environmental features and that such an approach can serve as a tool to guide conservation and management decisions.
