Araneomorphae from Estación de Biología Chamela IB-UNAM

Welcome

The IB-UNAM Chamela Biological Station inventory includes 251 Araneomorphae species documented with 2,849 standard views. Ecological and taxonomic data are currently being prepared for publication.

Spiders were collected in two half-hectare plots separated by 0.88 km, covering tropical deciduous and tropical wet forest. Each plot was visited three times from 2023 to 2025. Sampling included cryptic searching, day and night vegetation beating, pitfall traps, Berlese funnels for leaf litter, and direct collecting on vegetation "looking up" (LUP) and on the ground "looking down" (LUD). Leaf litter was processed with 12 Berlese funnels of 45 cm diameter per plot, and 30 pitfall traps were active for five days.
