Agriculture and the life histories of Mauritius kestrels

Habitat modification for agriculture is one of the greatest current threats to global biodiversity. Studies show large-scale population declines and short-term demographic impacts, but knowledge of the long-term effects of agriculture on individuals remains poor. This thesis examines the short- and long-term impact of agriculture on a reintroduced population of the Mauritius kestrel Falco punctatus, a tropical forest-dwelling raptor endemic to the island of Mauritius, that also utilises agricultural habitats. This population is a particularly appropriate model system, because complete life history data exists for individuals over a 22-year period, alongside detailed habitat and climate data. Agriculture has a short-term detrimental effect on Mauritius kestrel breeding success by exacerbating the seasonal decline in fledgling production. This is partly driven by the habitat-specific composition of the prey community that kestrels exploit to feed their chicks. The fledglings from agricultural territories tend to recruit in agricultural territories. This is largely due to poor natal dispersal and fine-scale spatial autocorrelation in the habitat matrix. Breeders do not respond to agriculture in the breeding territory by dispersing, unless the pair bond is broken. Therefore, individuals originating in agricultural territories tend to recruit, and remain in, agricultural territories throughout their lives. In addition to this, females from agricultural natal territories have shorter lifespans, schedule their peak reproductive output earlier in life, and exhibit more rapid senescence than non-agricultural females. The combination of this long-term effect and the adult experience of agriculture imposed by life history and environmental constraints, leads to a lower mean lifetime reproductive rate compared to females originating in non-agricultural habitats. These results demonstrate that agriculture experienced in early life has a lifelong effect on individuals. The effects can persist in time and space, with potentially delayed effects on population dynamics. These findings are important for understanding species’ responses to agricultural expansion.

Circles of support and accountability: criminal justice volunteers as the 'Deliberative public'

This paper provides a review of the role played by volunteers within one particular offender management and reintegration scheme in the United Kingdom. Circles of Support and Accountability (COSA) draw on the expertise of volunteer members of the public to create supportive monitoring frameworks around sex offenders following their release from prison. The paper presents evidence as to the motivations of these volunteers, and argues that they play a crucial role in the success of the scheme, as they provide an instrumentally-useful form of reintegrative social contact to a socially-excluded offender population, and perform a symbolically important role as representatives of the wider community in taking ownership of offender management practices on behalf of the wider society. This is particularly significant in grounding those processes in the communicative practices of the social sphere, providing powerful reasons for intervention that reinforce the work that COSA do.

Concordant Phylogeographies of 2 Malaria Vectors Attest to Common Spatial and Demographic Histories

The phylogeography of South American lineages is a topic of heated debate. Although a single process is unlikely to describe entire ecosystems, related species, which incur similar habitat limitations, can inform the history for a subsection of assemblages. We compared the phylogeographic patterns of the cytochrome oxidase I marker from Anopheles triannulatus (N = 72) and previous results for A. darlingi (N = 126) in a broad portion of their South American distributions. Both species share similar population subdivisions, with aggregations northeast of the Amazon River, in southern coastal Brazil and 2 regions in central Brazil. The average (ST) between these groups was 0.39 for A. triannulatus. Populations northeast of the Amazon and in southeastern Brazil are generally reciprocally monophyletic to the remaining groups. Based on these initial analyses, we constructed the a priori hypothesis that the Amazon and regions of high declivity pose geographic barriers to dispersal in these taxa. Mantel tests confirmed that these areas block gene flow for more than 1000 km for both species. The efficacy of these impediments was tested using landscape genetics, which could not reject our a priori hypothesis but did reject simpler scenarios. Results form summary statistics and phylogenetics suggest that both lineages originated in central Amazonia (south of the Amazon River) during the late Pleistocene (579 000 years ago) and that they followed the same paths of expansion into their contemporary distributions. These results may have implications for other species sharing similar ecological limitations but probably are not applicable as a general paradigm of Neotropical biogeography.

Four terebellines (Polychaeta, Terebellidae) with problematic taxonomic histories

Four taxa of terebellines with problematic taxonomic histories are redescribed. One is a new species that has been mis-identified for the last 37 years and one is allocated to a different genus from that to which it was previously assigned. Pista corrientis McIntosh, 1885 was described from Argentina and has been reported from several localities along the Brazilian coast. Examination of the holotype of P. corrientis revealed that the Brazilian specimens belong to a separate species, herein described as P. nonatoi sp. nov., and a redescription of the holotype of P. corrientis is provided. Pista sombreriana (McIntosh, 1885) was considered indeterminable due to the poor condition of the holotype. Our examination of the holotype showed that although it is poorly preserved most taxonomic characters are visible. The morphology of the lobes on anterior segments, especially those of segments 3-4, is closer to Lanicides than to Pista but considering that Lanicides is also poorly defined we redescribe P. sombreriana under its original designation. Finally, Eupolymnia turgidula (Ehlers, 1887) has been considered as a junior synonym of E. crassicornis (Schmarda, 1861) but a recent study resurrected it as a valid species of Terebella, which was the original generic designation. According to our examination of the holotype, E. turgidula does belong to Eupolymnia, but it is uncertain as to whether it is a valid species or a synonym of either E. crassicornis or E. magnifica (Webster, 1884).

A garantia constitucional do devido processo legal na investigação criminal defensiva: contraditório e ampla defesa

A presente monografia tem por finalidade, demonstrar a possibilidade de se adotar a Investigação Criminal Defensiva no Ordenamento Jurídico Brasileiro, tendo em vista as Garantias Constitucionais que a amparam no âmbito do Devido Processo Legal, em especial os Princípios Constitucionais da Ampla Defesa e do Contraditório, tendo em vista os benefícios que esse tipo de investigação poderia trazer à pessoa do indiciado, uma vez que poderia trazer um maior equilíbrio entre as partes, uma celeridade processual, além de uma maior amplitude de elementos que irão formar a convicção do órgão do Ministério Público.

Da revisão criminal e a indenização pelo erro judiciário

Esse trabalho tem por objetivo a analise do instituto da revisão criminal, do erro judiciário e a consequente indenização, a luz do direito processual penal brasileiro. Observando assim, a evolução da revisão criminal no decorrer do tempo, os seus aspectos legais, tais como, procedimento, finalidade e natureza jurídica, contemplando as vertentes doutrinárias a respeito do tema. Bem como as consequências de uma decisão, que contenha erro judiciário, sobre a dignidade da pessoa humana, discutindo se a indenização é realmente eficaz.

Oferta de trabalho, comportamento criminal e redistribuição de renda

Este trabalho desenvolve e calibra um modelo de equilíbrio dinâmico de crime. O objetivo É estudar e quantificar os determinantes do comportamento criminal: aparato de polícia, condições do mercado de trabalho, perfil etário da população, composição do capital humano, crescimento econônomico e desigualdade de renda. Diferentemente dos trabalhos anteriores, o modelo considerado aqui leva em conta a decisão individual sobre lazer. Isso permite capturar as diferenças no padrão da oferta de trabalho que há entre criminosos e não criminosos. Uma implicação é que a sensibilidade da taxa de crime aos fatores que afetam comportamento criminal é modificada. Adicionalmente, investiga-se a viabilidade de uma política de redistribuição de renda enquanto alternativa a política de segurança pública.
