“…This group displayed a sustained decrease in burn plots (Fig. 1c) that is consistent with several other studies (Niwa and Peck 2002;Warren et al 1987). Although spiders can endure long periods of starvation when prey capture is low, this group can either continue to sit-and-wait or move to a more productive environment (Wise 1993).…”

“…Spider families and subfamilies were grouped according to hunting guilds (McIver et al 1992;Niwa and Peck 2002;Post and Reichert 1977). Only five of the eight spider groups, however, were sufficiently abundant to be analyzed statistically: Diurnal Ambush (Thomisidae), Diurnal Pursuit (Lycosidae), Diurnal Stalk (Salticidae), Nocturnal Running (Gnaphosidae), and the only trapping group, Funnel Web (Agelenidae).…”

Conservation managers of oak woodlands have been reintroducing fire both as an ecological process per se and to assist in restoring native plant communities. To increase our understanding of the impacts of reintroduced fire on ground-dwelling invertebrates we examined the response of ants and spiders to a late season (autumn) prescribed fire conducted in a blue oak (Quercus douglasii) woodland ecosystem in northern California. Twelve 100 m 9 100 m plots were established, six plots received a burn treatment and the remaining six plots were unburned controls. Ants and spiders were sampled using pitfall traps left open continuously and collected approximately every 32 days. Sampling was conducted over a year, consisting of four pre-burn and nine post-burn collections. Abundance was analyzed using a repeated measures ANOVA, which showed seed-harvester ants decreased significantly in the two months following the fire. Total spider abundance also showed a significant decrease in two months, although this did not occur immediately after the burn. One spider hunting guild, the 'diurnal ambush' group (Thomisidae) remained suppressed for up to nine months. Correspondence analysis measures of ant species abundance with environmental and vegetation variables (percent rock, bare ground, plant species richness and height of herbaceous vegetation) were higher than expected by chance, which assists in explaining some of the responses. Findings from this study revealed that the reintroduction of autumn burns has modest and short-term effect on the invertebrates sampled, suggesting that late season fires are compatible with other conservation goals for oak woodland ecosystems.

“…A ocorrência de carabídeos e de estafilinídeos nos agroecossistemas está relacionada com as condições microclimáticas (Döring & Kromp 2003;Niwa & Peck 2002), com destaque para a temperatura e a umidade do solo oriunda da precipitação pluvial (Camero 2003;Álvarez-Duarte & Cataño 2007). Ressalta-se ainda que as condições do solo em sistemas de plantio direto elevam a densidade e a diversidade desses besouros predadores (House & Stinner 1983).…”

“…dead wood, litter layer), so that they may be very sensitive to this treatment. Many studies have examined the effects of burning on different arthropod groups and found these communities to be highly resilient (Niwa and Peck, 2002;Collett, 2003;Baker et al, 2004). However, there is no consensus about the effects of fire on arthropod communities in conifer forests and only a few specific groups have been studied (Santalla et al, 2002).…”

The effects of prescribed fire on the forest upper ground layer can have consequences for invertebrate communities. In the Canary Islands, prescribed fire is starting to be used as a tool to reduce wildfire risk, but the impacts of this management practice on the Canarian pine forest have not been investigated. The aim of this study is to explore the short-term effects of prescribed burning on the most abundant groups of ground-dwelling invertebrates. Three of six plots were randomly burnt and the other three were used as controls. Pitfall trapping was used to collect the grounddwelling invertebrates four months after burning. No differences were found in total richness, diversity, evenness and total abundance between treatments. Only Psocopteran abundance increased after fire. Litter depth, total vegetation cover and decayed wood cover were different between treatments. Canonical Correspondence Analyses (CCA) revealed differences in species composition between treatments using these environmental variables. It is concluded that the use of low-intensity prescribed burning in this stand did not have an important impact on the structural parameters of the ground-dwelling invertebrate community, but species composition changed. Care shoud be taken with valuable endemic, rare or sensible species.Key words: prescribed burning, invertebrate community, pine forest, Pinus canariensis, fire, soil ecology. ResumenEfectos a corto plazo de una quema prescrita de baja intensidad sobre los invertebrados epiedáficos de un pinar canario Los efectos del fuego prescrito sobre la capa superficial del suelo pueden tener consecuencias para las comunidades de invertebrados. Las quemas prescritas se están empezando a aplicar en las Islas Canarias como una herramienta para reducir el riesgo de incendios forestales, pero el impacto ecológico de estas prácticas aún no ha sido estudiado en el pinar canario. El objetivo de este trabajo es explorar los efectos a corto plazo de las quemas prescritas sobre los grupos más abundantes de invertebrados epiedáficos. Se establecieron seis parcelas, de las que tres fueron quemadas al azar y las otras tres se usaron como controles. Los muestreos de invertebrados se realizaron cuatro meses después de la quema mediante trampas de caída. No se encontraron diferencias entre tratamientos en riqueza, diversidad, equitatividad y abundancia total de invertebrados. En cuanto a los grupos, Psocoptera fue el único que incrementó su abundancia tras el fuego. Se encontraron diferencias significativas entre tratamientos en profundidad de mantillo, cobertura total de vegetación y cobertura de madera muerta en descomposición. Dichas variables se incluyeron en un Análisis Canónico de Correspondencia (CCA) revelando diferencias entre tratamientos en composición de especies. Se concluyó que, aunque las quemas prescritas no tienen un impacto notable sobre los parámetros estructurales de la comunidad de invertebrados, sí provocan cambios en la composición de especies, que deben ser valorados en presencia de espec...
