open access: yesDiversity
When analyzing the long-term viability of small, declining populations, it is essential to recognize that inbreeding and the erosion of genetic diversity are primarily driven by the effective population size, which is often a fraction of the total census

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

open access: yesJournal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

ABSTRACT This paper investigates whether nonbinary speakers’ imitation of extended voice onset time (VOT) in word‐initial English /p, t, k/ is impacted by whether they believe they are listening to a nonbinary or binary model speaker. Forty‐five nonbinary American English speakers participated in an online VOT shadowing task, and the results find that ...

Error detection is not necessary for representation

open access: yesMind &Language, EarlyView.
Some philosophers have recently proposed an error detection condition (EDC) for representation, such that for R$$ R $$ to be a representation for system S$$ S $$, S$$ S $$ must be capable of detecting errors in tokenings of R$$ R $$. We argue that this condition is unmotivated, and that it is too strong. We show that theories of representation that are
