1. Can plant hybridization and polyploidy lead to pollinator shift?
ABSTRACT Events of both hybridization and polyploidy are capable of completely restructuring the genome, modifying phenotypic traits and affecting ecological interactions. For plants, these changes may affect floral traits that are important for interactions with pollinators, which could lead to shifts in pollinator behavior and taxa between hybrids/polyploi

2. Effect of spray drying on the fatty acids content and nutritional indices of buffalo powdered milk
Abstract The buffalo’s reproductive seasonality determines the decrease in milk and cheese production generating economic losses on the production system. Among various food process, we find the spray-dryer as an essential tool which helps food conservation. We achieved the milk powder in three replicates and each repetition processed 10 L of buffalo milk.

3. Evidence of accelerated and altered pollen development after Imazapyr treatment in resistant sunflower
ABSTRACT Imazapyr (IM) treatment applied at early reproductive developmental stages have been associated with induced male sterility in sunflower (Helianthus annuus L.). The aim of this work was to determine the effects induced by two different doses of IM-treatment (1X and 2X; 80 and 160 g a.i.·ha-1) on pollen grain yield, pollen viability and on the exine

5. Inflammation: friend or foe of bovine reproduction?
Abstract Inflammation is not only the first line of defense of the organism but is also required in many reproductive processes such as ovulation, corpus luteum development, luteolysis, uterine clearance after insemination and post partum. Nevertheless, if excessive or persistent, inflammation can switch from a positive mechanism to a deleterious process, im

6. Reproductive physiology of the heat-stressed dairy cow: implications for fertility and assisted reproduction
Abstract Heat stress causes a large decline in pregnancy success per insemination during warm times of the year. Improvements in fertility are possible by exploiting knowledge about how heat stress affects the reproductive process. The oocyte can be damaged by heat stress at the earliest stages of folliculogenesis and remains sensitive to heat stress in the

7. Experiências que tangenciam o (in)visível e a mobilidade: etnografias em diálogo
Resumo: O processo de entrecruzamento de perspectivas e análises de duas pesquisadoras é o foco da discussão deste texto. Nele são discutidas as inquietações e questionamentos diante de solicitações experimentadas durante o trabalho etnográfico caracterizado pela longa duração tanto entre os Dogon (no Mali) como entre os Tsonga (no sul de Moçambi

9. Ploidy influences on metabolic substrate deposition of rainbow trout
ABSTRACT. Triploid fish are usually sterile. Thus, the energy and nutrients intended for sexual maturation may be available to enhance flesh quality and physical growth. The present study aimed to investigate differences in the metabolic substrates, lipids and proteins, between storage tissues from diploid and triploid female rainbow trout. Monthly, metaboli

10. Phenotypic correlation of characteristics in the gilt performance test with an average number of live-born piglets through all achieved births, during the reproductive exploitation
RESUMO A eficácia reprodutiva das porcas dita o nível de rentabilidade da própria produção, e o momento do teste e seleção de leitoas para reprodução (como os pais de uma geração futura) representa um momento muito importante. Dado o fato de que a seleção de leitoas para criação é parcialmente baseada no ganho de peso no teste, neste estudo e
