doi.org/10.1002/ece3... With great pleasure, I announce that another chapter of my doctoral thesis has been published in @ecol-evol.bsky.social. In our study, we explored how bird diversity varies with altitude—taxonomically, functionally, and phylogenetically—on Mt. Cameroon

Some 4.3 million observations of butterflies show that 59 of 136 species have declined in abundance over the past three decades, while no species has increased in abundance. Butterfly declines undoubtedly have large ecological consequences. In PNAS: www.pnas.org/doi/10.1073/...

Plants have limited resources for #defense. @ethanbass.bsky.social explores a @plosbiology.org study revealing how #plants limit costs by deploying cheap traits immediately, delaying spending on costly ones until a critical damage threshold is reached.

Scientists have found instances of sex reversal—where an individual has the physical features of one sex but the genetic makeup of the other—in five different Australian bird species. https://scim.ag/41Dvamo
