The excerpt establishes the dates, record count, protocol, and taxonomic totals, while the article adds geographic and sampling limitations: coverage is concentrated in Northern Italy, temporal effort is uneven, bait sampling underrepresents arboreal or hypogeic species, and absence data are constrained by heterogeneous sampling intensity."
