Replication Data for: First description of extrafloral nectaries in Opuntia robusta (Cactaceae): anatomy and ultrastructure
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The presence and structure of extrafloral nectaries (EFNs) in Opuntia robusta had not been investigated. We observed ants collecting nectar from young areoles. We recorded ants' behavior, quantified their presence on cladode sprouts, and associated ant number with sprouts size, air humidity, temperature, and daytime. We used light, scanning-electron, and transmission-electron microscopy to examine morphology, anatomy, and ultrastructure of the secretory spines in areoles in female and hermaphrodite individuals of O. robusta. Ants preferred narrower cladode sprouts with younger spines. Young cladodes develop areoles with modified and secretory spines as EFNs only active during the early growth phase of female and hermaphrodite individuals. EFNs are non-vascularized structures, with no stomata, that consist of three distinct tissues: a ba' .
