Plasticity syndromes in wild vertebrates: Patterns and consequences of individual variation in plasticity across multiple behaviours

From abstract:“Using a 40-year dataset on free-ranging Magellanic penguins, we find evidence of both positively and negatively correlated behavioural plasticities. Plasticity did not strongly affect lifetime reproductive success, but its effect on interannual performance varied significantly by environmental context: plasticity reduced success in average oceanic conditions, increased success in anomalously productive conditions and, contrary to expectation, did not buffer against […]

Ship collision risk threatens whales across the world’s oceans

Excerpt from UW News: “Thousands of whales are injured or killed each year after being struck by ships, particularly the large container vessels that ferry 80% of the world’s traded goods across the oceans. Collisions are the leading cause of death worldwide for large whale species. Yet global data on ship strikes of whales are hard to come by —

Maximizing biological insights from instruments attached to animals

From the highlights section: “Biologging sensors enable broad-scale, high-resolution measurements of the physiological, behavioral, demographic, social, and environmental interactions underpinning patterns in nature. We present a framework, case studies, and outstanding questions for integrating biologging data with theoretical concepts to facilitate process explanation and prediction.” Authors: Roxanne S. Beltran, A. Marm Kilpatrick, Simona Picardi, Briana Abrahms, Gabriel M. Barrile, William

Foot darkening with age in Spheniscus penguins: applications and functions

From the abstract: “We found that Spheniscus penguins have pale feet at hatching and the feet become darker with age throughout the lives of individuals. We showed that we can accurately predict the age structure of a colony of Magellanic penguins Spheniscus magellanicus, but not the ages of individual penguins, based on a sample of foot colors.” Authors: Ginger Rebstock,

Droughts reshape apex predator space use and intraguild overlap

From the Abstract:Droughts are increasing in frequency and severity globally due to climate change, leading to changes in resource availability that may have cascading effects on animal ecology. Although several studies have demonstrated the ecological impacts of drought, the behavioural responses of individuals that scale up to these broader-scale effects are not well known, particularly among animals in top trophic

Males miss and females forgo: Auditory masking from vessel noise impairs foraging efficiency and success in killer whales

Summary adapted from social media post by Anna Testorf: One of our recent studies illustrates how noise from large ships and other vessels decreases overall foraging success of fish-eating killer whales through a process known as auditory masking. Knowing how vessel noise affects killer whales can inform actions to mitigate noise and promote health and survival of these vulnerable populations

Anthropogenic impacts at the interface of animal spatial and social behaviour

From the abstract: “Here, we review studies of animal behaviour at the spatial–social interface to understand and predict how human disturbance affects animal movement, distribution and intraspecific interactions, with consequences for the conservation of populations and ecosystems. By understanding the spatial–social mechanisms linking human disturbance to conservation outcomes, we can better design management interventions to mitigate undesired consequences of disturbance.”

Scale at the interface of spatial and social ecology

From the abstract: “We propose three key innovations that incrementally build upon each other […] These conceptual innovations cast our understanding of the relationships between social and spatial dimensions of animal ecology in a new light, allowing a more holistic understanding and clearer hypothesis development for animal behaviour.” Authors: Simona Picardi, Briana L. Abrahms and Jerod A. MerkleJournal: Philosophical Transactions

Global expansion of human-wildlife overlap in the 21st century

“We show that the potential spatial overlap of global human populations and 22,374 terrestrial vertebrate species will increase across ~56.6% and decrease across only ~11.8% of the Earth’s terrestrial surface by 2070 […] The strong spatial heterogeneity of future human-wildlife overlap found in our study makes it clear that local context is imperative to consider, and more targeted area-based land-use

Increasing environmental variability inhibits evolutionary rescue in a long-lived vertebrate

“Using a multidecadal dataset on Magellanic penguins, we show that despite strong selection on body size, some environmental conditions favored larger bodies, and others favored smaller bodies, thus preventing consistent evolution in one direction or the other […] Such findings highlight that fluctuating selection can be driven by environmental variability, and these processes could eliminate the possibility of evolutionary rescue
