Tangled and drowned: a global review of penguin bycatch in fisheries

, 2017
Penguins are the most threatened group of seabirds after albatrosses. Although penguins are regularly captured in fishing gear, the threat to penguins as a group has not yet been assessed.

“There is a Place for Us Here”: Exploring Sex, Gender, Reproduction, Sexual Behavior, and Orientation Narratives Supporting Students With Queer Genders in Biology Courses

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Queer undergraduates describe a climate in STEM fields and classrooms that is both hostile to and silent on queer identities, leading to experiences of social exclusion, devaluation as a scientist, and discrimination. In the few studies that have specifically focused on trans and non‐binary undergraduates (i.e., students with queer genders ...

Facilitating macrosystem biology with organismal‐scale airborne remote sensing: Challenges and opportunities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Emergent ecosystem properties, such as population and trait distributions, biodiversity and energy and water fluxes, occur because of the dynamic interactions of individuals in their environment.

Modeling Huddling Penguins

PLoS ONE, 2012
We present a systematic and quantitative model of huddling penguins. In this mathematical model, each individual penguin in the huddle seeks only to reduce its own heat loss. Consequently, penguins on the boundary of the huddle that are most exposed to the wind move downwind to more sheltered locations along the boundary.

Flavor SU(3) symmetry and QCD factorization in $B \to PP$ and $PV$ decays

, 2011
Using flavor SU(3) symmetry, we perform a model-independent analysis of charmless $\bar B_{u,d} (\bar B_s) \to PP, ~PV$ decays. All the relevant topological diagrams, including the presumably subleading diagrams, such as the QCD- and EW-penguin exchange ...

Environmentally induced stress affects fitness of bold and shy alike: A long‐term study of personality and feather corticosterone in Arctic‐breeding kittiwakes

Journal of Animal Ecology, EarlyView.
Quantifying how individuals differ as their environment changes around them is crucial to predict population responses to climate change. By incorporating personality, physiology and life‐history the authors show that while environmental change is likely to impact the whole population equally, when individuals are most impacted will vary across the ...

Using virtual simulation in a geographic information system to optimize abundance survey designs when logistic and biological conditions are constrained

Wildlife Society Bulletin, 2012
Estimating wildlife abundance is central to many resource and ecosystem management problems. Early statistical work on wildlife abundance estimation focused on small‐scale problems, but there is a growing need for such information at large spatial scales.

Fatal Sarcocystis falcatula Infection in Three Penguins

Frontiers in Veterinary Science, 2019
Sarcocystis falcatula is a well-known cause of fatal pneumonia in some birds, particularly Old World psittacines. Here we describe fatal sarcosystosis due to S.

Enhanced electroweak penguin amplitude in B-->VV decays

, 2005
We discuss a novel electromagnetic penguin contribution to the transverse helicity amplitudes in B decays to two vector mesons, which is enhanced by two powers of mB/Lambda relative to the standard penguin amplitudes.

Vocal individuality cues in the African penguin (Spheniscus demersus): a source-filter theory approach

Scientific Reports, 2015
The African penguin is a nesting seabird endemic to southern Africa. In penguins of the genus Spheniscus vocalisations are important for social recognition.
