1. In vitro embryo production in buffaloes: from the laboratory to the farm
Abstract Transvaginal follicular aspiration technique together with in vitro embryo production are the biotechnological alternatives currently available to support genetic improvement breeding programs in buffalo species. However, aspects related to animal management, lack of knowledge of the metabolic needs and biochemical peculiarities of gametes and embry

2. Características morfológicas do estômago de jaguatirica (Leopardus pardalis - Linnaeus, 1758)
RESUMO Leopardus pardalis é uma das espécies de felinos neotropicais mais estudadas em seus aspectos ecológicos, porém informações de questões morfofisiológicas do trato digestório não são encontradas na literatura. Visando contribuir com tais informações, o objetivo deste artigo foi caracterizar a morfologia do estômago dessa espécie. Nesta p

3. Sexual dimorphism in the catfish Genidens genidens (Siluriformes: Ariidae) based on otolith morphometry and relative growth
RESUMO Genidens genidens é uma espécie suscetível a declínios populacionais, tendo em vista as peculiaridades de sua reprodução. Diferenças morfométricas entre os sexos são observadas na literatura, e essas diferenças também devem ser evidentes no desenvolvimento dos otólitos. O padrão de crescimento é uma das características biológicas mais

4. Riparian vegetation structure and soil variables in Pandeiros river, Brazil
Resumo Este estudo analisou as variações florísticas, estruturais e suas relações com variáveis do solo em dois trechos de vegetação ripária em uma região ecotonal entre savana e zonas semi-áridas. Propomos a hipótese de que, apesar da proximidade entre as áreas amostradas, as condições do solo são distintas e levam a mudanças na estrutura e

5. Mangrove Soil in Physiographic Zones in the Sao Francisco River Estuary
ABSTRACT Mangrove ecosystem dynamics and diverse human activities have led to a need for studies that give us a better understanding of the peculiarities of their soils. The objective of this study was to evaluate the physical and chemical soil attributes of mangrove forests located in the São Francisco River estuary, related to local ecological conditions

6. Evolution of DNMT2 in drosophilids: Evidence for positive and purifying selection and insights into new protein (pathways) interactions
Abstract The DNA methyltransferase 2 (DNMT2) protein is the most conserved member of the DNA methyltransferase family. Nevertheless, its substrate specificity is still controversial and elusive. The genomic role and determinants of DNA methylation are poorly understood in invertebrates, and several mechanisms and associations are suggested. In Drosophila, th

7. The plant cell cycle: Pre-Replication complex formation and controls
Abstract The multiplication of cells in all living organisms requires a tight regulation of DNA replication. Several mechanisms take place to ensure that the DNA is replicated faithfully and just once per cell cycle in order to originate through mitoses two new daughter cells that contain exactly the same information from the previous one. A key control mech

8. Comparative study on the quality of oil extracted from two tucumã varieties using supercritical carbon dioxide
Abstract The vast Amazon region has considerable territorial peculiarities and plant species diversity, sometimes from the same botanical family, which can exhibit significant differences in physicochemical properties. From this diversity, two species stand out – Amazonas tucumã (Astrocaryum aculeatum Meyer) and Pará tucumã (Astrocaryum vulgare Mart.).

9. Intra- and interspecific chromosome polymorphisms in cultivated Cichorium L. species (Asteraceae)
Endive (Cichorium endivia L.) and chicory (C. intybus L.) both have 2n = 18, but until now, there has been no detailed karyomorphological characterization. The present work evaluated five accessions of each species using FISH with rDNA probes and fluorochrome staining with CMA and DAPI. Both species presented distinct banding patterns after fluorochrome stai

10. Consumo de lácteos caprinos no Rio Grande do Sul : oferta de produtos, aceitabilidade de queijo, perfil do consumidor e consumo de lácteos não bovinos / Consumption of goat milk products in Rio Grande do Sul: offer of products, cheese acceptance, consumer profile and consumption of non-bovine milk products
This dissertation paper is divided into four studies, all of them concerned with the trade of goat milk products and non-bovine milk products. The first study aimed to identify the goat milk products offered to consumers in the retail of Porto Alegre, capital of Rio Grande do Sul state, Brazil, as well as to verify the availability and price variation of the

Estrutura e riqueza de hepáticas (Marchantiophyta) epifíticas em áreas fragmentadas de Cerrado com borda natural e antrópica / Estrutura e riqueza de hepáticas (Marchantiophyta) epifíticas em áreas fragmentadas de Cerrado com borda natural e antrópica / Structure and richness of the epiphytic liverworts (Marchantiophyta) in fragmented areas of Cerrado with natural edge and anthropogenic / Structure and richness of the epiphytic liverworts (Marchantiophyta) in fragmented areas of Cerrado with natural edge and anthropogenic
The damage caused by the proliferation of edge in forest cover, referred to as edge effects are extensive, may occur over large spatial scales influencing species composition, structure and ecological processes in boundaries of ecosystems. However, studies have shown highly variable response patterns of the taxonomic group studied in relation to the landscap

12. Características vegetativas e reprodutivas das plantas e fatores abióticos do meio e suas relações com a alocação de biomassa floral e a seleção sexual em angiospermas / Vegetative and reproductive characteristics of plants and abiotic factors of the environment and their relations with floral biomass allocation and sexual selection in angiosperms
Plants are sessile organisms exposed to the effects of environmental stress. The flowers are fundamental structures in the evolution of angiosperms, because through them is sexual reproduction. For this, the flowers exhibit strategies that help the plant to achieve better reproductive success. Animals visit flowers in search of resources, however, to carry p
