FeLIX is a restriction factor for mammalian retrovirus infection

The paper identifies soluble truncated Env proteins from endogenous FeLV as antiviral restriction factors that inhibit retrovirus infection through competitive receptor binding.

Natural selection reverses the exaggeration of a male sexually selected trait, which increases female fitness.

The paper uses experimental evolution to show that male-specific predation reduces exaggerated male traits in beetles, indirectly increasing female fitness through genetic correlations.

Seasonal and annual fluctuations of deer populations estimated by a Bayesian state-space model

This study uses a Bayesian state-space model to estimate seasonal and annual fluctuations in sika deer populations in Japan, identifying factors like snowfall and nuisance control affecting population dynamics.
