Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods
Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

Abstract Protected areas cannot halt biodiversity loss in isolation; integrating them with surrounding human‐dominated landscapes is critical. However, this integration is challenged by substantial landscape heterogeneity at protected area borders, making it difficult to determine cross‐border changes in ecosystem service provision.
