Systematics and Diversity of Annelids
In this Special Issue, we address the state of the art of the systematics of the main annelid groups and the improvements in the diversity they hold, with special emphasis on the latest discoveries in well-studied areas, expeditions to unsurveyed areas or environments, or the use of novel techniques that allow for the improvement of biodiversity knowledge. We are hoping that this Special Issue will provide a platform facilitating a review of current knowledge on the subject, identifying current research problems, as well as indicating directions and research trends for the future.
Hydroides of the World
Serpulid polychaetes are a unique and highly specialised group of marine segmented worms that have adapted to inhabiting self-secreted calcareous tubes attached to a wide range of hard substrates. These animals are found across all depths and habitats of the world’s oceans, and some form mutually beneficial associations with live corals. The genus Hydroides is of special concern and importance, as it is not only the largest, but also one of the most ecologically and economically important groups of marine invertebrates because it includes notorious biofoulers and common bioinvaders that travel around the world hitchhiking on ships’ hulls. This is the first fully illustrated guide to this notorious serpulid genus of calcareous tubeworms, providing a comprehensive diagnostic treatment of all known species of the genus Hydroides. This important reference provides reliable identification tools to distinguish Australian tubeworms from potential alien invaders that constantly arrive from overseas and threaten Australia’s maritime transport, trade and mariculture.
Biosocial Synchrony on Sumba
Biosocial Synchrony on Sumba: Multispecies Relationships and Environmental Variations in Indonesia examines biosocial change in the Austronesian community of the Kodi by examining multispecies interactions between select biota and abiota. Cynthia T. Fowler describes how the Kodi people coordinate their mundane and ritual practices with polychaetes and celestial bodies, and how this synchrony encourages and is encouraged by social and ecological variations. Fowler grounds her anthropogenic environmental research with information from geospatial science, marine ecology, astronomy, physics, and astrophysics.

Oxtankah: una ciudad prehispánica en las tierras bajas del área maya
La ciudad de Oxtankah desempeñó un papel crucial sociopolítico establecido por las comunidades en la porción sur del actual estado de Quintana Roo, con lo cual se concluye que sus habitantes lograron un alto grado de sustentabilidad ecológica que les permitió diversificar la economía local, basada en la explotación de recursos marinos, costeros y lacustres, al igual que en la agricultura, recolección, cacería, apicultura y producción de sal, entre otros.
