Convergence of marine megafauna movement patterns in coastal and open oceans. [PDF]
Proc Natl Acad Sci U S A, 2018 Significance Understanding the key drivers of animal movement is crucial to assist in mitigating adverse impacts of anthropogenic activities on marine megafauna. We found that movement patterns of marine megafauna are mostly independent of their evolutionary histories, differing significantly from patterns for terrestrial animals.

The need for long-term population monitoring of the world’s largest fish
Endangered Species Research, 2022 Many large marine species are vulnerable to anthropogenic pressures, and substantial declines have been documented across a range of taxa. Many of these species are also long-lived, have low individual resighting rates and high levels of individual ...

Shaken, not stirred: blue whales show no acoustic response to earthquake events
Royal Society Open Science, 2022 Quantifying how animals respond to disturbance events bears relevance for understanding consequences to population health. We investigate whether blue whales respond acoustically to naturally occurring episodic noise by examining calling before and after

Translating the terrestrial mitigation hierarchy to marine megafauna by‐catch [PDF]
Fish and Fisheries, 2018 AbstractIn terrestrial and coastal systems, the mitigation hierarchy is widely and increasingly used to guide actions to ensure that no net loss of biodiversity ensues from development. We develop a conceptual model which applies this approach to the mitigation of marine megafauna by‐catch in fisheries, going from defining an overarching goal with an ...

Improving Marine Megafauna Knowledge with eDNA: A French Story
Biodiversity Information Science and Standards, 2023 In the current context of large-scale biodiversity loss (Díaz et al. 2019), it is urgent to carry out biodiversity inventories in order to investigate spatial and temporal variations. Among the available methods, environmental DNA (eDNA) (Taberlet et al. 2018) combined with molecular metabarcoding (Valentini et al.

Five Decades of Marine Megafauna Surveys from Micronesia [PDF]
Frontiers in Marine Science, 2016 Long-term data are critical for assessing the status, trends, abundance, and distributions of wildlife populations. However, such data streams are often lacking for protected species, especially highly mobile marine vertebrates. Using five decades of aerial surveys, we assessed changes in marine megafauna on the insular coral reef ecosystem of Guam ...

The importance of sample size in marine megafauna tagging studies [PDF]
Ecological Applications, 2019 AbstractTelemetry is a key, widely used tool to understand marine megafauna distribution, habitat use, behavior, and physiology; however, a critical question remains: “How many animals should be tracked to acquire meaningful data sets?” This question has wide‐ranging implications including considerations of statistical power, animal ethics, logistics ...

Ecological impacts of climate change on Arctic marine megafauna
Trends in Ecology & Evolution, 2023 Global warming affects the Arctic more than any other region. Mass media constantly relay apocalyptic visions of climate change threatening Arctic wildlife, especially emblematic megafauna such as polar bears, whales, and seabirds. Yet, we are just beginning to understand such ecological impacts on marine megafauna at the scale of the Arctic.
