So cool to see ಕನ್ನಡ (Kannada) -- my native language in @asn-amnat.bsky.social 😍
This is a reminder that @asn-amnat.bsky.social publishes abstracts in both English and your native language, using your native alphabet. You can see and read those online. Here is a screenshot of a great example. Love seeing this in my favorite journal.

Do older birds claim better territories, and does this drive age biases in space over time? Woodman et al. use 45 years of data to suggest that habitat quality - not age - shapes spatial demography.

Yuan et al. discover why female frogs grow larger: male competition drives size when mates are scarce. Monogamous species show the strongest link, and both temperature and predation shape this dance.

Evolution in one sex is often affected by selection acting on the opposite sex. Geeta Arun et al. explore this using fruit flies and find that responses to selection are largely parallel between sexes.
