How much redistribution and poverty reduction is being accomplished in Latin America through social spending, subsidies, and taxes? Standard fiscal incidence analyses applied to Argentina, Bolivia, Brazil, Mexico, Peru, and Uruguay using a comparable methodology yields the following results. Direct taxes and cash transfers reduce inequality and poverty by nontrivial amounts in Argentina, Brazil, and Uruguay but less so in Bolivia, Mexico, and Peru. While direct taxes are progressive, the redistributive impact is small because direct taxes as a share of GDP are generally low. Cash transfers are quite progressive in absolute terms, except in Bolivia where programs are not targeted to the poor. In Bolivia and Brazil, indirect taxes more than offset the poverty-reducing impact of cash transfers. When one includes the in-kind transfers in education and health, valued at government costs, they reduce inequality in all countries by considerably more than cash transfers, reflecting their relative size.

Between 2003 and 2009, Argentina’s social spending as a share of gross domestic product increased by 7.6 percentage points. Benefit incidence analysis for 2003, 2006, and 2009 suggests that the contribution of cash transfers to the reduction of disposable income inequality and poverty rose markedly between 2006 and 2009, primarily due to the introduction of a new noncontributory pension program—known as the pension moratorium—in 2004. The redistributive impact of the expansion of public spending on education and health was also sizable and equalizing, but to a lesser degree. An assessment of fiscal funding sources puts the sustainability of the redistributive policies into question, unless nonsocial spending is significantly cut. [ABSTRACT FROM AUTHOR]

Abstract: Prey remains recovered from puma (Puma concolor) scat were analyzed in order to identify taphonomic features produced on them by this predator. Mammal remains are abundant in puma scat, but recognition of bone remains decreases as prey size increases. Modifications produced by digestion are strong. However, micromammal bones show a gradation in preservation that includes well preserved specimens. Data presented here and their interpretation may possibly be extrapolated to zooarchaeological or paleontological assemblage. [Copyright &y& Elsevier]

Progeny tests employing molecular markers allow the identification of individuals originated by sexual means among the offspring of a facultative apomict. The objective of this work was to evaluate the effect of the pollination timing on the proportion of sexually formed individuals in progenies of a facultative apomictic Paspalum notatum genotype. Progeny families of approx. 30 plants each were generated at five different pollination times: 1–3 d pre‐anthesis; at anthesis; and 2, 4 and 6 d post‐anthesis. Cytoembryological analyses indicated that approx. 17 % of the ovules carried a meiotic cytologically reduced embryo sac in florets formed simultaneously with those used for crosses. The parental plants and the five F1 families were analysed using RAPD molecular markers. Ninety‐five oligonucleotides were assayed on the progenitors in order to search for male‐specific bands. Eight primers presenting clear polymorphic bands were selected for use in the progeny tests. The proportion of sexually produced progeny reached 3·4 % before anthesis and 20 % at anthesis, while pollination after anthesis generated only maternal plants. A second progeny of 97 plants obtained from pollination at anthesis produced 16 off‐type plants (16·5 %), of which only one was a BIII hybrid (2n + n). Our results indicate that pollination at anthesis allows the greatest potential for sexuality to be expressed in this facultative apomictic genotype. When pollination is delayed as soon as 2 d after anthesis, only the aposporous sacs develop endosperm through pseudogamy to set seed. [ABSTRACT FROM PUBLISHER]
