Lifetime fitness (lifetime reproductive success) and annual survival are heritable and genetically correlated in wild female baboons! Moreover, nearly all of the genetic variance in LRS can be attributable to survival to first reproduction. Out at Evolution now: academic.oup.com/evolut/advan...

Lifetime fitness and annual survival are heritable and highly genetically correlated in a wild primate population

We estimated the additive genetic variance (VA) and heritability of lifetime and time-limited fitness in a wild female baboon population in Kenya. We found

Researchers have identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. https://scim.ag/4nTQ3nq

How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers have now identified superparamagnetic macrophages in the livers of rock pigeons (Columba livia) to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.

A U.S. federal mandate to make scholarly papers free to read could triple the government’s bill for publishing fees to $937 million by 2030—an increase most research agencies aren’t prepared for, says a report released by Congress’s spending-watchdog agency. https://scim.ag/3Q3y29F

U.S. agencies aren’t ready for the rising cost of making research papers free, report warns

Science agencies could soon face nearly $1 billion publishing bill, Congressional analysts find

May 23, 2006 is the hatch date of the world's most famous lance-tailed manakin. PXVm has starred in Netflix's 'Dancing with the Birds', and been highlighted for years by the Cornell Lab Manakin Cam. How do you celebrate such a momentous day? By dancing! Here he is today, with his current beta GSGm:

New opportunity for PhD fellowships at interface of ecology & evolution from the Simons Foundation. Application deadline June 30, 2026. My interpretation is that this applies to prospective PhD students & those accepted/not yet matriculated. Full details: www.simonsfoundation.org/grant/simons...

Simons Graduate Fellowships in Ecology and Evolution

The purpose of these awards is to provide support for students entering U.S.-based Ph.D. programs with a plan to perform research in ecology and evolution. While we will consider all projects in ecolo...

New paper out in Biological Reviews📝🚨 When trying to explain why female birds engage in extra-pair copulations/paternity, we mostly focus on the benefits. But what about the costs? Should we not consider the downsides of the behavior we try to understand? 🧵 onlinelibrary.wiley.com/doi/10.1002/...

The costs of extra‐pair behaviours in birds

Extra-pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecol...

Today the members of the Evolution, Ecology, and Behavior graduate program at Indiana University celebrated the upcoming retirement of Dr. Ellen Ketterson. Ellen was a bastion of civility and scientific excellence. The program would not be what it is without her presence over these past decades.
