title: Fiscal laxity or inflection? Fiscal policy in Roussef’s government and the economic crisis

description: Abstract Fiscal policy played a leading role in the debate on the trajectory of the Brazilian economy in the first half of 2010 to explain the economic slowdown and subsequent recession, both in orthodox and heterodox contributions. Orthodox economics points to uncontrolled public spending as being responsible for the fiscal deterioration, which would have led to worsening agents' expectations and falling investments. Heterodox economics, in a roughly opposite interpretation, points to an inflection of fiscal policy that, reducing spending, particularly investment, at the beginning of the decade, would have compromised the policy-inducing capacity in a demand-led growth model. This article aims to empirically evaluate these explanations. In addition to a descriptive analysis of the data, we propose a vector autoregression (VAR) model to examine how the fiscal policy elements pointed out by each of the perspectives discussed here have affected economic growth. In particular, we aim to investigate whether they are able to explain the downturn and the recession in the period analyzed. The results indicate, contrarily to the orthodox view, that spending did not skyrocket compared to previous governments, and that movements in output tend to precede changes in the fiscal outcome. They also point to the importance of public investment in determining the pace of activity, confirming a central element of the heterodox approach. However, by revealing that up to 2014 public spending continued to grow, indicates the insufficiency of the heterodox thesis to explain the slowdown in previous years and the depth of the subsequent recession. Given this, we present additional explanatory elements to understand the period.

title: Prohibiting pet crayfish does not consistently reduce their availability online

description: Abstract The pet trade is a significant source of introductions of non-indigenous aquatic species, such as crayfish. To test whether legislation that regulates the ownership of ornamental animals for aquariums had the desired effect of reducing the availability of those pets, classified advertising websites were monitored for sales of crayfish in jurisdictions with and without legislation regulating the ownership of crayfish. Advertisements from Canadian provinces with legislation against owning crayfish were compared to provinces without such legislation. The population adjusted number of advertisements for crayfish, and number of distinct sellers of crayfish, was significantly lower in one of two provinces that prohibited crayfish compared to provinces that permitted crayfish. This mixed outcome suggests that legislation alone does not consistently reduce online trade in crayfish.

title: Economic policy, institutions and social classes: an analysis of the workers’ party governments in Brazil (2002-2016)

description: Abstract From a political economy perspective, this paper analyzes the Lula and Rousseff administrations in Brazil, focusing on the relationship between macroeconomic policy and its political, economic and social constraints. It shows that both administrations implemented relatively successful projects of income redistribution. However, contradicting part of the literature, the paper advocates that they cannot be characterized as neoliberal nor developmentalist. It also advocates that the “new macroeconomic matrix”, set forward by the Rousseff administration, represented more than a mere change in economic policy: it constituted an inflection point in the Workers’ Party (PT) administrations, since it meant the undoing of a “classes coalition pact” agreed between Lula and businesses segments, which supported PT’s governments since the “Letter to the Brazilian People” (2002). As of 2008, the conjunction of a world economic crises, ongoing deindustrialization and a set of permissive conditions exposed the limits of the coalition in force, hindering the continuity of the redistributive project.

title: Infestation of two shrimp species of the genus Palaemon Fabricius, 1798 (Decapoda, Palaemonidae) by an isopod of the genus Probopyrus Giard & Bonnier, 1888 (Bopyridae) from the Brazilian southeast coast

description: Abstract We determined the infestation rate of Probopyrus sp. in populations of Palaemon pandaliformis (Stimpson, 1871) and P. northropi (Rankin, 1898) in the Ubatumirim River, localized in a mangrove ecosystem on Ubatumirim Beach, northern coast of the state of São Paulo, Brazil. Samplings were carried out monthly from April 2003 to March 2004. Monthly prevalence varied from 0 to 4.94 % for P. pandaliformis, and from 0 to 4.54 % for P. northropi. This is the first record of Probopyrus sp. infesting the studied species in this region. Species of Probopyrus (Giard and Bonnier, 1888) seem to have a high plasticity with regard to palaemonid hosts, as they can be parasites of shrimps in both Palaemon (Fabricius, 1798) and Macrobrachium (Spence Bate, 1868). The linear relationships between the parasite and host sizes suggest that the parasite infests both hosts early in their development. We concluded that the infestation of Probopyrus sp. has little impact on Palaemon populations, mostly due to the low prevalence of infestation.

title: Cryptocurrencies and the new challenges faced by the monetary system: a post-Keynesian perspective

description: Abstract In 2008, Satoshi Nakamoto, the pseudonym of an unknown person, launched ‘Bitcoin’, a decentralized cryptocurrency, aiming at circumventing banks or governments and returning to a more ‘austere’ and quantity-controlled monetary system. After Bitcoin, several other cryptocurrencies were created, and a debate on whether these instruments could ever replace what we currently use as ‘money’ surfaced. Ten years since its creation, it is clear that Bitcoin did not reach its main goal but raised important discussions within the framework of Monetary Authorities. Therefore, this work has two main objectives. The first is to show that, from a post-Keynesian theoretical perspective, Bitcoin cannot stand up to fiduciary currencies because it is much closer to being a highly volatile speculative asset than a currency capable of assuming the prime functions in a capitalist economy. The second objective is to point out the consequences of this discussion within the framework of the monetary authorities, with emphasis on the proposals of central bank cryptocurrencies.

title: Population structure of two freshwater amphipods (Crustacea: Peracarida: Hyalellidae) from southern Brazil

description: Abstract Two recently described amphipods species from southern Brazil, Hyalella georginae Streck and Castiglioni, 2017 and Hyalella gauchensis Streck and Castiglioni, 2017, had their population structures characterized by sex, females’ ovigerous condition, cephalothorax length (mm), size-class frequency distribution, sex-ratio, reproductive period, and recruitment. The specimens were collected with a dip net from a stream source (H. georginae) and from a water reservoir (H. gauchensis) in the Palmeira das Missões municipality, state of Rio Grande do Sul, Brazil, from August 2012 to July 2013 (12 months). Both species showed a bimodal frequency distribution for total and seasonal size classes, with males larger than females. Overall, the sex ratio favored females when analyzed monthly and seasonally. Ovigerous females were recorded throughout the year, with higher frequency in spring (H. georginae) and summer (H. gauchensis), characterizing a seasonal reproduction. Both species showed continuous recruitment, with greater intensity in the spring. The population structure of these two Hyalella species had similar features, showing continuous recruitment and seasonal reproduction related to their life-history strategies, which promote adaptations to their habitat.

title: Financialization of firms strategies in argentine primary production during the kirchnerist governments (2003-2015)

description: Abstract This paper analyzes the accumulation strategies of primary producers in Argentina from 2003 to 2015. We compare the economic surplus of these sectors and how it is used to increase productive capacities, financial investment and capital flight, as well as changes in the composition of assets. We use aggregate data on the whole formal economy provided by the Argentine tax agency. Accounting data from the primary sectors’ largest companies is also presented. We conclude that because firms have financialized accumulation strategies, productive investment is subordinated to strategies that prioritize liquidity and capital flight, causing a process of “investment reticence”. Therefore, we discuss the role of these primary sectors in promoting national economic development, as is suggested by different economic perspectives.

title: Allometry and sexual dimorphism of the Neotropical freshwater anomuran Aegla marginata Bond-Buckup & Buckup, 1994 (Crustacea, Anomura, Aeglidae)

description: Abstract This study analyzes ontogenetic allometry in Aegla marginata Bond-Buckup & Buckup, 1994, a freshwater crustacean, in order to evaluate the growth pattern and the presence of sexual dimorphism, using a multivariate approach. The specimens were sampled from streams in Intervales State Park, São Paulo State, Brazil. For each specimen, we measured the following structures: carapace length and width, chelae height and length, and abdomen length. Allometry was evaluated using Jolicoeur’s multivariate allometric coefficient. Our results showed that for females, ABL (abdomen length) and LCH (left chelae heigh) presented positive allometry; LCL (left chelae length) and RCH (right chelae heigh) isometry; and CL (carapace length), CW (carapace width), and RCL (right chelae length) negative allometry. For males, RCH, LCH, and LCL presented positive allometry; RCL (right chelae length) isometry; and CL, CW, and ABL negative allometry. In addition, sexual dimorphism was amplified with body size.

title: Distribution of European and African species of genus Diaptomus (Copepoda: Calanoida: Diaptomidae): a track analysis

description: ABSTRACT The distributional patterns of 13 species of Diaptomus Westwood, 1836 were analyzed using the panbiogeographical method of track analysis. Locality records were compiled from the literature and mapped for the construction of individual tracks for each species. These tracks were superimposed to find the generalized tracks. Four generalized tracks were found: (1) Siberia, Central Europe, and Iceland; (2) Northern Italy, southern France, central Spain, northern Algeria, and northern Morocco; (3) Southern France, central Spain, and northern Morocco; (4) Southern Italy, Sicily, and Albania. Five biogeographic nodes were found: (A) Southwestern Iberia, (B) Southeastern Iberia, (C) Central Iberia, (D) Cantabria, at the intersections of generalized tracks 2 and 3; and (E) Italian Peninsula Islands, at the intersection of generalized tracks 2 and 4. The main massing of the species of Diaptomus studied is located in the Iberian peninsula, where six of the species do occur. A model based on the fragmentation and differentiation of already widespread ancestors during the late Mesozoic and early Cenozoic, related to the opening the North Atlantic Ocean and the formation of the Mediterranean Sea, is proposed as a most parsimonious explanation for the observed patterns of geographic vicariance.

title: Population and reproductive biology of two caprellid species (Crustacea: Amphipoda) associated to Sargassum cymosum (Phaeophyta: Fucales) on the southeast coast of Brazil

description: Abstract Caprellid amphipods are common crustaceans at Sargassum beds of southeastern Brazil and constitute an important link between primary producers and marine consumers. The goal of this study is to evaluate population and reproductive biology of two caprellid species: Paracaprella tenuis Mayer, 1903 and Pseudaeginella montoucheti Quitete, 1971. Sargassum cymosum Agardh, 1820 samples were collected monthly between October 2010 and September 2011 in a rock shore in southeastern Brazil. The caprellids were identified, counted, measured and classified as males, immature females, sexually mature females, ovigerous females and juveniles. Eggs were counted and measured. Higher densities of P. tenuis and P. montoucheti were found mainly in winter and lower densities in fall and summer. Density variation is probably related to organic matter supply and substrate availability. Both species showed continuous reproduction with reproductive peaks. Pseudaeginella montoucheti larger egg volume indicates a longer incubation period. The egg volume was directly related to female size. The number of eggs was weakly related to female size, indicating that fecundity may be driven by other factors, such as the physiological conditions. Sex ratio deviated for males suggests a higher longevity of males. The present study highlighted important data of two caprellids species that occur in algal beds of different regions.

title: Decapod abundance and species richness in the bycatch of Xiphopenaeus kroyeri (Heller, 1862) fishery, Santa Catarina, southern Brazil

description: Abstract We aimed to analyze the crustacean bycatch from the Xiphopenaeus kroyeri fishery in the Santa Catarina State and compare the bycatch’s biomass to that of the target species. Shrimp and environmental factors were sampled monthly from July 2010 through June 2011. For each crustacean species, we calculated the number of individuals, the relative abundance and the occurrence frequency. The relative abundance was classified as very abundant (Va), abundant (Ab) or low abundance (La), while the occurrence frequency was labeled continuous (Co), accessory (Ac) or accidental (Ad). We observed a total richness of 28 species, which is considered high for a subtropical region. Brachyura was the most frequent taxon (74%) followed by Penaeiodea (18%). Five species were considered Va (Arenaeus cribrarius, Callinectes danae, C. ornatus, Isochelis sawayai and Pleoticus muelleri), and eight species were considered Co (A. cribrarius, C. danae, C. ornatus, Farfantepenaeus paulensis, Hepatus pudibundus, Libinia spinosa, Litopenaeus schmitti and Sicyonia dorsalis), suggesting that the studied environment is heterogeneous and provides a variety of microhabitats, enabling many species to coexist. Therefore, the high species richness observed demonstrates the ecological importance of this region and thus the necessity of strategies aiming to minimize the impacts caused by trawling fisheries.
