O golpe de Estado no Chile e o cinema documental no ICAIC

Carolina Aguiar
Este artigo analisa o impacto do golpe de Estado no Chile no ICAIC. Após 1973, o ICAIC fortaleceu relações cinematográficas anteriores, possibilitou uma vasta produção de exilados chilenos e apoiou documentários que denunciaram a ditadura. Essas ações, porém, foram permeadas por tensões oriundas dos debates políticos entre os dois modelos de socialismo latino-americanos nos anos 1970.

Data from: Comparative analysis of adaptive and neutral markers of Drosophila mediopunctata populations dispersed among forest fragments

Marcos R. D. Batista, Rafael E. S. Penha, Silvia H. Sofia & Louis B. Klaczko
Comparison of adaptive and neutral genetic markers is a valuable approach to characterize the evolutionary consequences of populations living in environments threatened by anthropogenic disturbances, such as forest fragmentation. Shifts in allele frequencies, low genetic variability, and a small effective population size can be considered clear signs of forest fragmentation effects (due to genetic drift) over natural populations, while adaptive responses correlate with environmental variables. Brazilian Atlantic Forest had its landscape drastically reduced and fragmented....

Data from: Structure and genetic variability of golden mussel (Limnoperna fortunei) populations from Brazilian reservoirs

Pâmela Juliana Furlan-Murari, Claudete De Fatima Ruas, Eduardo Augusto Ruas, Lucas Milanez Benício, Angela Maria Urrea-Rojas, Angela Rocio Poveda-Parra, Emerson Murari, Ed Christian Suzuki De Lima, Felipe Pinheiro De Souza & Nelson Mauricio Lopera-Barrero
The golden mussel, Limnoperna fortunei a highly invasive species in Brazil, has generated productive, economical, and biological impacts. To evaluate genetic structure and variability of L. fortunei populations present in fish farms in the reservoirs of Canoas I (CANFF), Rosana (ROSFF), and Capivara (CAPFF) (Paranapanema river, Paraná, Brazil), eight microsatellite loci were amplified. Five of those eight loci resulted in 38 alleles. The observed heterozygosity (Ho) was lower than the expected heterozygosity (He) in all...

Data from: Tree seedling responses to leaf-cutting ants herbivory in Atlantic Forest restoration sites

Jose Marcelo Domingues Torezan, Jessica Magon Garcia, Alexandre De Mello Bordignon & Gessi De Sousa Gonzaga
Leaf-cutting ants (LCA) are generalist herbivores capable of causing severe plant damage. Negative impacts of ant herbivory vary according to the density of nests and availability of palatable plants; however, it is not yet clear how these herbivores affect tropical forest restoration sites. To investigate how LCA preference affects plant species performance, we evaluated the herbivory of Atta sexdens rubropilosa on native tree species seedlings in Atlantic Forest restoration sites. We expected pioneer species to...

Data from: Insights on the functional composition of specialist and generalist birds throughout continuous and fragmented forests

Luiz Dos Anjos, Gabriela Menezes Bochio, Hugo Reis Medeiros, Bia De Arruda Almeida, Barbara Rocha Arakaki Lindsey, Larissa Corsini Calsavara, Milton Cezar Ribeiro & José Marcelo Domingues Torezan
A decline in species number often occurs after forest fragmentation and habitat loss, which usually results in the loss of ecological functions and a reduction in functional diversity in the forest fragments. However, it is uncertain whether these lost ecological functions are consistently maintained throughout continuous forests, and so the importance of these functions in continuous forests remains unknown. Point counts were used to assess both the taxonomic and functional diversity of specialist and generalist...

A “Dirty” Footprint: Soil macrofauna biodiversity and fertility in Amazonian Dark Earths and adjacent soils

Segalla, Thibaud Decaëns, Herlon S. Nadolny, Clara P. Peña‐Venegas, Cláudia M. B. F. Maia, Amarildo Pasini … & George G. Brown
Amazonian rainforests once thought to hold an innate pristine wilderness, are increasingly known to have been densely inhabited by populations showing a diverse and complex cultural background prior to European arrival. To what extent these societies impacted their landscape is unclear. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre-Columbian societies as a result of more sedentary habits. Much is known of the chemistry of these soils, yet their...

Data from: Beta diversity patterns of bats in the Atlantic Forest: how does the scale of analysis affect the importance of spatial and environmental factors?

Carolina Batista, Isaac De Lima & Marcos Lima
Aim: Environmental and spatial factors are broadly recognized as important predictors of beta diversity patterns. However, the scale at which beta diversity patterns are evaluated will affect the outcoming results. For example, studies at larger scales will usually find spatial processes as the main predictor of beta diversity patterns. In this study we evaluate how beta diversity patterns change when analyses are conducted at different scales by reducing the scale of analysis in a hierarchical...

Data from: Recommendations for assessing earthworm populations in Brazilian ecosystems

Herlon Nadolny, Alessandra Santos, Wilian Demetrio, Talita Ferreira, Lilianne Dos Santos Maia, Ana Caroline Conrado, Marie Bartz, Marilice Garrastazu, Elodie Da Silva, Dilmar Baretta, Amarildo Pasini, Fabiane Vezzani, José Paulo Sousa, Luis Cunha, Jerome Mathieu, Patrick Lavelle, Jörg Römbke & George Brown
Earthworms are often related to fertile soils and frequently used as environmental quality indicators. However, to optimize their use as bioindicators, their populations must be evaluated together with environmental and anthropogenic variables regulating earthworm communities. In this review we identify the earthworm, soil chemical, physical, environmental and management-related variables evaluated in 124 published studies that quantified earthworm abundance (>7300 samples) in 765 sites with different types of climate, soils, land use and management systems in...

Data and scripts from: Total evidence phylogenetic analysis reveals polyphyly of Anostomoides and uncovers an unexpectedly ancient genus of anostomid fishes

Brian Sidlauskas, Fernando Assega, Bruno Melo, Claudio Oliveira & José Birindelli
The nearly 150 species of Anostomidae comprise one of the most diverse and taxonomically dynamic families of Neotropical freshwater fishes. A recent revision of the enigmatic and poorly diagnosed genus Anostomoides demonstrated that it contains two valid species, each with complicated taxonomic histories; however, that study did not address their phylogenetic placement. Herein, we provide the integrated molecular and morphological data and scripts used to demonstrate their distant evolutionary relationship, and thus the polyphyly of...
