When mesophotic meets shallow: First records of deep‐associated reef fishes in a well‐studied tropical bay under the influence of spring–summer upwelling

Journal of Fish Biology, EarlyView.
Abstract We document the first records of reef fishes typically associated with mesophotic environments on shallow (<10 m) coral reefs inside a well‐studied tropical bay. The vermilion snapper Rhomboplites aurorubens and the pygmy angelfish Centropyge aurantonotus, usually restricted to deeper (>40 m) shelf habitats along the Brazilian coast, were ...

Beyond Literacy: Embracing Illiteracies as Strategic Resistance in Citizenship Education

European Journal of Education, Volume 61, Issue 3, September 2026.
ABSTRACT This article reconsiders the role of citizenship illiteracies in citizenship education, particularly in challenging contexts where direct confrontation is untenable. Traditionally, citizenship education often equates citizenship literacies with positive civic engagement, overlooking the potential value of illiteracies as forms of resistance ...
