Cumulative human impacts across the world's oceans are considerable. We therefore
examined a single model taxonomic group, the penguins (Spheniscidae), to explore how …

Animal biometrics is an emerging field that develops quantified approaches for representing
and detecting the phenotypic appearance of species, individuals, behaviors, and …

Photographic mark–recapture is a cost‐effective, non‐invasive way to study populations.
However, to efficiently apply photographic mark–recapture to large populations, computer …

As important marine mesopredators and sensitive indicators of Antarctic ecosystem change,
penguins have been a major focus of long‐term biological research in the Antarctic …

Current evidence of phenological responses to recent climate change is substantially biased
towards northern hemisphere temperate regions. Given regional differences in climate …

The field of marine tagging and tracking has grown rapidly in recent years as tag sizes have
decreased and the diversity of sensors has increased. Tag data provide a unique view on …

The rise of antibiotic resistance demands the acceleration of molecular diversification
strategies to inspire new chemical entities for antibiotic medicines. We report here on the …

Current guidelines for instrumenting birds state that external devices should not exceed 3–
5% of the birds' body mass; however, the energetic consequences of carrying any given …

Range shift is the primary short-term species response to rapid climate change, but it is often
hampered by natural or anthropogenic habitat fragmentation. Different critical areas of a …

An important first step in studying the demography of wild animals is to identify the animals
uniquely through applying markings, such as rings, tags, and bands. Once the animals are …
