The Ground-Dwelling Arthropod Community of Península Valdés in Patagonia, Argentina

Predation emerges as a key factor shaping the composition and abundance of ground-dwelling arthropods in Península Valdés, Argentina. This study, the first to employ intensive, planned sampling over three summers (2005–2007), revealed that predators dominate the community, with ants (Hymenoptera: Formicidae) leading in abundance, followed by beetles (Coleoptera) and spiders (Araneae). Two new species were identified from this data. The logarithmic distribution of abundances suggests limited controlling factors, while the predominance of predators highlights their critical role in structuring arid Patagonian ecosystems. These insights offer valuable guidance for conservation efforts in UNESCO-listed Península Valdés.
