1. EVALUATION OF DIVERSITY AND GENETIC STRUCTURE AS STRATEGIES FOR CONSERVATION OF NATURAL POPULATIONS OF Dalbergia nigra (Vell.) Allemão ex Benth.
ABSTRACT: The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR).

4. Cutting and regeneration of roots and seedlings from seeds of Eugenia candolleana DC. at different maturity stages
Resumo: O potencial para gerar novas raízes e até plantas inteiras, mesmo após a remoção de grande parte de suas reservas, é uma característica típica das sementes monoembriônicas de espécies do gênero Eugenia. Trabalhos anteriores mostraram que sementes de Eugenia podem produzir plântulas mesmo quando apenas ¼ de sua massa está presente, inclu

5. Sexual and reproductive traits of the pearl oyster shrimp Pontonia margarita (Decapoda: Palemonidae), symbiotically inhabiting the mantle cavity of the rugose pen shell Pinna rugosa (Bivalvia: Pinnidae)
ABSTRACT Symbiosis between decapods and mollusks provides a unique opportunity to examine some of the evolutionary strategies employed by marine invertebrates. We describe the sexual and reproductive traits of the pearl oyster shrimp, Pontonia margarita Verril, 1869, found symbiotically inhabiting the mantle cavity of the rugose pen shell, Pinna rugosa Sower

6. Scorpions and life-history strategies: from evolutionary dynamics toward the scorpionism problem
Abstract This work aims to contribute to the general information on scorpion reproductive patterns in general including species that can be noxious to humans. Scorpions are unusual among terrestrial arthropods in several of their life-history traits since in many aspects their reproductive strategies are more similar to those of superior vertebrates than to

7. Características evolutivas en Prosopis spp.: citogenética, genética e hibridaciones
Abstract Prosopis is a primitive genus in the Mimosoid’s clade characterized by disjunctions in its distribution areas and the difficulty in establishing its phylogeny. This paper presents an updated literature review on the evolutionary, cytogenetic, genetic and hybridization characteristics of the genus. The available data suggest that it diverged early

8. Cyanobacterial nitrogenases: phylogenetic diversity, regulation and functional predictions
Abstract Cyanobacteria is a remarkable group of prokaryotic photosynthetic microorganisms, with several genera capable of fixing atmospheric nitrogen (N2) and presenting a wide range of morphologies. Although the nitrogenase complex is not present in all cyanobacterial taxa, it is spread across several cyanobacterial strains. The nitrogenase complex has also

9. In the picture: disulfide-poor conopeptides, a class of pharmacologically interesting compounds
Abstract During evolution, nature has embraced different strategies for species to survive. One strategy, applied by predators as diverse as snakes, scorpions, sea anemones and cone snails, is using venom to immobilize or kill a prey. This venom offers a unique and extensive source of chemical diversity as it is driven by the evolutionary pressure to improve

10. Evolution of seed dispersal in the Cerrado biome: ecological and phylogenetic considerations
ABSTRACT The investigation of the phylogeny of a group of organisms has the potential to identify ecological and evolutionary processes that have been occurring within a community. Seed dispersal is a key process in the life cycle of vegetation and reflects different reproductive strategies of plants to a set of ecological and evolutionary factors. Knowing t

11. Regulation of gene expression: Cryptic β-glucoside (bgl) operon of Escherichia coli as a paradigm
Bacteria have evolved various mechanisms to extract utilizable substrates from available resources and consequently acquire fitness advantage over competitors. One of the strategies is the exploitation of cryptic cellular functions encoded by genetic systems that are silent under laboratory conditions, such as the bgl (β-glucoside) operon of E. coli. The bg

12. Public management, policy capacity, innovation and development
In this paper we discuss the question of what factors in development policy create specific forms of policy capacity and under what circumstances developmentoriented complementarities or mismatches between the public and private sectors emerge. We argue that specific forms of policy capacity emerge from three interlinked policy choices, each fundamentally ev
