This section of the Handbook of Zoology is intended as a comprehensive and exhaustive account of the biology of the taxa Gastrotricha, Nematoda, Nematomorpha, Priapulida, Kinorhyncha, Loricifera, Gnathostomulida, Micrognathozoa, Rotifera, Seisonida and Acanthocephala, covering all relevant topics such as morphology, ecology, phylogeny and diversity. The series is intended to be a detailed and up-to-date account of these taxa. As was the case with the first edition, the Handbook is intended to serve as a reliable resource for decades. Many of the taxa of this volume are comparatively unknown to many biologists, despite their diversity and importance for example in meiofaunal communities (Gastrotricha, Rotifera, Gnathostomulida), their fascinating recent discoveries (Loricifera and Micrognathozoa), their importance as parasites (many nematodes, Nematomorpha, Acanthocephala) and their importance for evolutionary questions (e.g. Priapulida, Gastrotricha). The groups covered range from those poor in species (such as Micrognathozoa with 2 known species) to the species-rich and diverse Nematoda and their ca. 20.000 described species. While each taxon is covered by one chapter, nematodes are treated in several chapters dedicated to their structural, taxonomic and ecological diversity.

In March 2020, the COVID-19 pandemic swept the world causing physical, emotional, economic, and social upheaval in every part of the globe. It also catalyzed a renewed interrogation, by music education faculty in higher education, of philosophies and practices that had long gone unexamined. Music Education on the Verge: Stories of Pandemic Teaching and Transformative Change is a collection of narratives by music teacher-educators describing how they responded to the disruption of the COVID-19 pandemic with, and for, their students. Through these stories, the authors step back and reflect on the events, challenges, triumphs, and innovations discovered as they prepared the next generation of music educators in this time of crisis. They tell stories of reexamining old frameworks, discovering new affordances of technologies, humanizing pedagogy, deepening culturally responsive and sustaining experiences, and creating space for democratic practices. Each chapter offers examples of innovative music pedagogy that can be adapted and applied by music educators and music teacher educators with their students. Collectively, they paint a picture of possibilities, challenging music teacher-educators- and educators in all fields- to seek out openings and pursue pedagogies of change as we move forward into a post-pandemic world.
