Abstract and Figures

An inventory of the invertebrate fauna found in the leaf crown and phytotelm of tank bromeliads (Aechmea lingulata and Hohenbergia ramageana) was carried out in the Parque Estadual Dunas do Natal (Natal Dune State Park or NDSP), Natal, Rio Grande do Norte State, northeastern Brazil. A total of 874 invertebrate specimens were obtained, belonging in 33 taxa within the Mollusca, Annelida, Arachnida, Myriapoda, and Insecta, and most of the taxonomic determinations reported were taken to rank of family. Insects and chelicerates were the most taxonomic diverse and abundant taxa (mature and immature forms considered). Immature forms were recorded for 15 taxa, indicating a significant role of tank bromeliads as a breeding site. Larvae of scirtid beetles (Insecta, Coleoptera) were the most abundant group recorded in the present inventory. Detritivore, predator, and herbivore feeding guilds were recorded. The detritivore guild was the most representative both in number of taxa and abundance, indicating a detritus-processing food chain community. The relevance of inventorying and monitoring bromeliad–inhabiting biota as a tool for environmental risk assessment is discussed.

葉冠とフィトテルムに見られる無脊椎動物の目録タンクアナナス (Aechmea lingulata と Hohenbergia ramageana) の採集は、Parque Estadual Dunas do Natal (Natal Dune State Park または NDSP) で行われました。ナタール、リオグランデドノルテ州、ブラジル北東部。軟体動物内の 33 の分類群に属する、合計 874 の無脊椎動物標本が得られました。環形動物、クモ類、多足類、および昆虫類、および報告された分類学的決定のほとんどは、家族のランクに取られました。昆虫と鋏角最も分類学的に多様で豊富な分類群でした（成熟および未成熟の形態が考慮されます）。 15 の分類群で未熟な形態が記録されており、繁殖地としてのタンクアナナスの重要な役割。カブトムシ (昆虫、鞘翅目) の幼虫は、で記録された最も豊富なグループでした。現在の在庫。食肉食獣、捕食者、草食動物の摂食ギルドが記録されました。破壊者ギルドは両方とも最も代表的だった分類群の数と豊富さで、デトリタス処理の食物連鎖コミュニティを示しています。アナナスに生息する目録作成と監視の関連性環境リスク評価のツールとしての生物相について説明します。
