| description |
A survey of the spider community composition and diversity was carried out in grasslands and
woods in three localities: Colonia Pellegrini, Paraje Galarza and Estancia Rincón (Iberá province Reserve). Pit
fall traps, leaf litter sifting, foliage beating, hand collecting and sweep nets were used. Shannon’s diversity index,
evenness, Berger-Parker’s dominance index, β and γ diversity were calculated, and a checklist of spider fauna
was compiled. Species richness was estimated by Chao 1, Chao 2, first and second order Jack-knife. A total of
4 138 spiders grouped into 150 species from 33 families of Araneomorphae and two species from two families
of Mygalomorphae were collected. Five species are new records for Argentina and eleven for Corrientes prov ince. Araneidae was the most abundant family (39.8%), followed by Salticidae (10.9%), Anyphaenidae (7.9%),
Tetragnathidae (7.4%), and Lycosidae (5.5%). The other families represented less than 5% of the total catch.
The web-builder guild had the highest number of specimens and the highest richness index. The abundance,
observed richness, Shannon diversity and evenness indexes were highest in Colonia Pellegrini woodland and
Paraje Galarza grassland. Alpha diversity represented 89% of the gamma; the remaining 11% corresponded to
β diversity. According to the indexes, between 67% and 97% of the existing spider fauna was represented in the
collected specimens from Iberá. Rev. Biol. Trop. 57 (1-2): 339-351. Epub 2009 June 30. |

Se estudió la composición y diversidad de la comunidad de arañas de la Reserva provincial Iberá, Corrientes, Argentina. Se realizaron capturas en bosque y pastizal en Colonia Pellegrini, Paraje Galarza y Estancia Rincón por medio de las técnicas de muestreo: trampas “pit-fall”, tamizado, golpeteo de follaje, observación directa y red de arrastre. Las arañas se agruparon en gremios y se compiló un inventario. La similitud entre localidades y unidades ambientales se midió con el índice de Jaccard, y se calcularon los índices de diversidad de Shannon, equitabilidad, dominancia de Berger-Parker, y la diversidad beta y gamma. Para estimar la riqueza de especies se utilizó Chao 1, Chao 2, Jackknife 1 y 2. En total se recolectaron 4 138 arañas, se identificaron 33 familias y 150 especies de Araneomorphae, y dos familias y dos especies de Mygalomorphae. Cinco especies son nuevos registros para Argentina y 11 para la provincia de Corrientes. Araneidae fue la familia más abundante (39.8%), seguida por Salticidae (10.9%), Anyphaenidae (7.9%), Tetragnathidae (7.4%), Lycosidae (5.5%), y las restantes familias representaron menos del 5% de la captura total. El gremio de arañas tejedoras de telas orbiculares fue el de mayor abundancia y riqueza de especies. Entre las unidades ambientales, la mayor abundancia, riqueza y diversidad se verificó en el bosque de Colonia Pellegrini y en el pastizal de Paraje Galarza. La diversidad α fue alta, representó el 89% de la diversidad gamma, y la diversidad β constituyó el 11% restante. Según los diferentes índices se capturó entre el 67% y el 97% de las especies que están presentes en la Reserva. 2022-07-04T11:27:56Z 2022-07-04T11:27:56Z 2009-03 Artículo Ávalos, Gilberto, et al., 2009.
