Bats from Fazenda Intervales, Southeastern Brazil: species account and comparison between different sampling methods

Assessing the composition of an area's bat fauna is typically accomplished by using captures or by monitoring echolocation calls with bat detectors. The two methods may not provide the same data regarding species composition. Mist nets and harp traps may be biased towards sampling low flying species, and bat detectors biased towards detecting high intensity echolocators. A comparison of the bat fauna of Fazenda Intervales, southeastern Brazil, as revealed by mist nets and harp trap captures, checking roosts and by monitoring echolocation calls of flying bats illustrates this point. A total of 17 species of bats was sampled. Fourteen bat species were captured and the echolocation calls of 12 species were recorded, three of them not revealed by mist nets or harp traps. The different sampling methods provided different pictures of the bat fauna. Phyllostomid bats dominated the catches in mist nets, but in the field their echolocation calls were never detected. No single sampling approach provided a complete assessment of the bat fauna in the study area. In general, bats producing low intensity echolocation calls, such as phyllostomids, are more easily assessed by netting, and bats producing high intensity echolocation calls are better surveyed by bat detectors. The results demonstrate that a combined and varied approach to sampling is required for a complete assessment of the bat fauna of an area.

Debris flow magnitudes: a global catalog

The episodic occurrence of debris flow events in response to stochastic precipitation and wildfire events makes hazard prediction challenging. Previous work has shown that frequency-magnitude distributions of non-fire-related debris flows follow a power law, but less is known about the distribution of post-fire debris flows. As a first step in parameterizing hazard models, we use frequency-magnitude distributions and cumulative distribution functions to compare volumes of post-fire debris flows to non-fire-related debris flows. Due to the large number of events required to parameterize frequency-magnitude distributions, and the relatively small number of post-fire event magnitudes recorded in the literature, we collected data on 73 recent post-fire events in the field. The resulting catalog of 988 debris flow events is presented as an appendix to this article. We found that the empirical cumulative distribution function of post-fire debris flow volumes is composed of smaller events than that of non-fire-related debris flows. In addition, the slope of the frequency-magnitude distribution of post-fire debris flows is steeper than that of non-fire-related debris flows, evidence that differences in the post-fire environment tend to produce a higher proportion of small events. We propose two possible explanations: 1) post-fire events occur on shorter return intervals than debris flows in similar basins that do not experience fire, causing their distribution to shift toward smaller events due to limitations in sediment supply, or 2) fire causes changes in resisting and driving forces on a package of sediment, such that a smaller perturbation of the system is required in order for a debris flow to occur, resulting in smaller event volumes.

O Guesa em New York: republicanismo e americanismo em Sousândrade

Esta tese analisa a poesia de Joaquim de Sousa Andrade (1832-1902), ou Sousândrade, e tem por objetivo discutir o imaginário político republicano como elo de ligação entre os poemas O Guesa, especialmente o Canto Décimo (1877), Novo Éden: Poemeto da adolescência, 1888-1889 (1893), Harpa de Ouro (189?) e a continuação O Guesa, o Zac (1902). A cronologia dessas obras indica que é a partir dos anos vividos por Sousândrade nos Estados Unidos que as figurações da República passam a permear os seus escritos. No Canto Décimo, gestado em Nova York, Sousândrade traça um panorama da sociedade estadunidense na década de 1870 e, embora haja críticas à certas práticas econômicas nesse canto, conforme discutiremos com vagar, destaca-se a emulação do poeta em exaltar aquele modelo sociopolítico. Essa atitude do escritor maranhense afinava-se com a visão de brasileiros imigrados nos Estados Unidos naquele mesmo período, os quais formavam uma rede de pensadores liberais comprometidos com a modernização do Brasil. Esse diálogo transatlântico que começa a ser traçado entre Estados Unidos e Brasil caracteriza uma alternativa ao modelo de civilização europeu até então em voga, tema ainda pouco explorado pela historiografia literária. De volta a pátria, Sousândrade dá prosseguimento ao seu fazer poético e, além do seu engajamento na nova conjuntura política do país, dedica-se à construção do mito fundador da República brasileira nos poemas concebidos desde 1893. A trajetória do poeta republicano foi marcada pelo seu anseio de progresso e modernização do Brasil, tarefa na qual ele empenhou-se política e literariamente.
