Assemblage organization of surface-active arthopods in Sonoran Desert dune ecosystems
I tested the hypothesis, in northwestern Sonora, thet temporal patterns of organization among surface-active arthropods resemble each other in dune and interdune habitats from coastal (Puerto Peñasco) and inland (Gran Desierto) dune ecosystems. Seasonal (October and May) counts of arthropods at 12-h...

| description | I tested the hypothesis, in northwestern Sonora, thet temporal patterns of organization among surface-active arthropods resemble each other in dune and interdune habitats from coastal (Puerto Peñasco) and inland (Gran Desierto) dune ecosystems. Seasonal (October and May) counts of arthropods at 12-h intervals were made from pitfall-trap grids at both sites. Although the coastal interdune had the greatest plant cover (32%) rarefaction analysis showed its expected species richness of arthropods, E(Sn), to be similar to richness in the inland interdune. In both interdune habitats, E(Sn) was significantly greater in spring then fall, and generally much greater then in dune habitats. Both E(Sn) and trap-capture frequencies averaged higher at night than during the day in all habitats. Values of Hill's N2 diversity and Hill's modified E5 evenness in coastal and inland interdune assemblages were similar at night in spring. Otherwise, few correlations involving habitat, season, and diel time were evident, except that evenness was usually greatest at night. Neither plant cover nor recent precipitation at the coast were correlated with species richness. Species turnover (Sorensen's Index) was greater between inland habitats then between interdune habitats when sites were compared. Overall, evidence for consistent resemblance in assemblage organization between similar habitats-specially dunes-over seasonal and diet time was not strong.

En el noroeste de Sonora probé la hipótesis de la similitud de los patrones de organización temporal de artrópodos en hábitats de dunas e interdunas de los ecosistemas de la costa (Puerto Peñasco) y continental (Gran Desierto). Conteos de artrópodos con intervalos de 12-h fueron efectuados temporalmente (Octubre y Mayo) usando transectos de trampas de agujero (pitfall trap) en ambos sitios. Aunque el área de interduna en la costa tenía la mayor cobertura vegetal (32%), el análisis de rarefaction" mostró que la riqueza calculada de especies de artrópodos, E(Sn), es similar a la del área de interduna continental. En ambos hábitats de interduna, E(Sn) fue significativamente mayor en primavera que en otoño, y generalmente mayor que en los hábitats de dunas. Ambos valores, E(Sn) y la frecuencia de captura por trampa, promediaron valores más altos durante la noche que durante el día en todos los hábitats. los valores de diversidad de Hill N2 y el modificado E5 de similitud de Hill, en las congregaciones de interduna de la costa y continental fueron similares durante la noche en primavera. Por otro lado, hubo muy poca correlación entre hábitats, temporada y hora del día, excepto en que la similitud fue mayor durante la noche. Ni la cobertura vegetal ni ia reciente precipitación pluvial en la costa tuvieron correlación con la riqueza de especies cuando fueron comparadas. El índice de incorporación de especies (índice de Sorensen) fue mayor entre hábitats continentales que el de Interdunas. En general, la evidencia de similitudes en la organización de las congregaciones, entre hábitats semejantes, especialmente en dunas, durante temporadas y hora del día no fue evidente.
