AbstractCarabid beetles (Coleoptera: Carabidae) provide important ecological services and are frequently used as a bio-indicator in monitoring environmental quality. The abundance and diversity of carabids is usually determined using pitfall trapping, but trap catches are difficult to compare between studies due to variation in trapping effort. The standardization of the catch for trapping effort has not been previously addressed in a global analysis of studies in the literature.The aims of this study are (i) to define a method for estimating the effect of trapping effort on the size of the pitfall catch, and (ii) to explore factors related to study designs, sampling method, study origin, and level of data aggregation to determine how these factors affect the catch per unit effort in pitfall trapping.We conducted a meta-analysis on the activity-density and diversity of carabids across studies, based on published data from Europe and North-America to analyse whether standardization of catch measurements might be possible. Data were extracted from 104 publications, spanning a period of 42 years.The total catch was proportional to the number of trap days, and ranged from 0.19-9.53 beetles/(trap day) across studies (95% range), with a mean of 1.33 beetles/(trap day). The number of species was allometrically related to the trapping effort defined as the product of the number of traps, their perimeter and the time of exposure in the field, and characterized by a power exponent of 0.25. Species richness ranged across studies from 2.30-13.18 species/(m day)0.25 (95% range) with a mean of 7.15 species/(m day)0.25. The size of the catch and the number of species were higher in crops with narrow as compared to wide rows. There was no significant change in abundance or diversity of carabids in arable land over the 42 years covered. We also found that increasing trapping effort may not yield more accurate results.The results show that it is possible to standardize activity-density-based catches and species diversity for trapping effort across studies using a power transformation, allowing meta-analysis of such data, e.g. to elucidate factors affecting abundance and diversity of the focal taxa.

AbstractAimsWith the global atmospheric nitrogen (N) deposition increasing, the effect of N deposition on terrestrial plant diversity has been widely studied. Some studies have reviewed the effects of N deposition on plant species diversity; however, all studies addressed the effects of N deposition on plant community focused on species richness in specific ecosystem. There is a need for a systematic meta-analysis covering multiple dimensions of plant diversity in multiple climate zones and ecosystems types. Our goal was to quantify changes in species richness, evenness and uncertainty in plant communities in response to N addition across different environmental and experimental contexts.MethodsWe performed a meta-analysis of 623 experimental records published in English and Chinese journals to evaluate the response of terrestrial plant diversity to the experimental N addition in China. Three metrics were used to quantify the change in plant diversity: species richness (SR), evenness (Pielou index) uncertainty (Shannon index).Important FindingsResults showed that (i) N addition negatively affected SR in temperate, Plateau zones and subtropical zone, but had no significant effect on Shannon index in subtropical zones; (ii) N addition decreased SR, Shannon index and Pielou index in grassland, and the negative effect of N addition on SR was stronger in forest than in grassland; (iii) N addition negatively affected plant diversity (SR, Shannon index and Pielou index) in the long term, whereas it did not affect plant diversity in the short term. Furthermore, the increase in N addition levels strengthened the negative effect of N deposition on plant diversity with long experiment duration; and (iv) the negative effect of ammonium nitrate (NH4NO3) addition on SR was stronger than that of urea (CO(NH2)2) addition, but the negative effect of NH4NO3 addition on Pielou index was weaker than that of CO(NH2)2 addition. Our results indicated that the effects of N addition on plant diversity varied depending on climate zones, ecosystem types, N addition levels, N type and experiment duration. This underlines the importance of integrating multiple dimensions of plant diversity and multiple factors into assessments of plant diversity to global environmental change.

A ação humana vem transformando as paisagens florestais em fragmentos isolados de remanescentes, podendo levar muitas espécies à extinção. Desta maneira se faz necessário a realização de estudos para o conhecimento e adequada caracterização da fauna de solo e, por conseguinte sua preservação. O objetivo do presente trabalho foi caracterizar a fauna de coleópteros em um fragmento florestal ao entorno da cidade de Uruará, PA. Para tanto, utilizou-se armadilhas tipo pitfall não iscadas para a coleta. O fragmento foi dividido em quatro transectos, com armadilhas instaladas ao longo da borda (T1), 50 m (T2), 100 m (T3) e 200 m (T4). Foram coletados 196 indivíduos, classificados em sete famílias e 34 espécies/morfoespécies. A família que apresentou a maior abundância foi a Curculionidae representando 56,40% da abundância, tendo o gênero Xyleborus sp. a maior dominância. Através do índice de Diversidade de Shanon, observou-se que a área de borda apresentou a menor diversidade e maior dominância (índice de Berger-Parker). Através da curva de acumulação e dos estimadores de espécies, ficou evidenciado que a área de estudo apresenta uma quantidade superior de espécies ao encontrado no presente estudo, e que pesquisas futuras são necessárias para um melhor acompanhamento das alterações que ocorrem nos fragmentos florestais com a finalidade de propor medidas de menor impacto e preservação dessa biodiversidade. Abundance and Diversity of Ground Dwelling Beetles (Arthropoda: Insecta) in Fragments of Shrubbery Vegetation (Capoeira) in the Surroundings of the Urban Zone of Uruará City-PA, Brazil   Abstract. Human action has been transforming forest landscapes into isolated fragments, which may lead to the extinction of many species. Therefore, studies should be conducted to provide knowledge and the appropriate characterization of soil fauna, and, consequently, its preservation. This study was aimed to characterize the fauna of beetles in a forest fragment in the surroundings of Uruará city, PA. Unbaited pitfall traps were used for the collection of the beetles. The fragment was divided into four transects, with traps installed along the border (T1), 50 m (T2), 100 m (T3) and 200 m (T4). 196 individuals classified in seven families and 34 species/morphospecies were collected. The most abundant family was the Curculionidae accounting for 56.40% of the abundance, with gender Xyleborus sp. being the most dominant. Measurement with the Shannon Diversity Index for measurement showed lower diversity and greater dominance (Berger-Parker index) in the border area. Using species accumulation curves and estimators it became evident that the study area had a greater number of species than those found in the present study, and that further studies are needed to better monitor changes in forest fragments in order to propose measures to reduce the impact on this biodiversity and preserve it.
