摘要:Abstract(#br)A deterministic simulation model was used to test the hypothesis that utilization of untested juvenile bucks could be an alternative to old buck strategy in dissemination of superior genetic materials in dairy goats breeding program. We compared the genetic and econo...

摘要:Abstract(#br)Studies on breeding systems and flower morphology are valuable to infer how environmental factors impose evolutionary change in plants. This study focused on the characterization of floral morphs and reproductive systems in Pachycereus pringlei and how this iconic co...

摘要:... The average milk and cheese yield, fat, protein and lactose contents were very similar between the two breeding systems. Milk casein was higher (P=0.04) in intensive herds than in semiextensive herds (4.07% vs 3.51%), whereas the urea content was higher in semi-extensive he...

摘要:Abstract(#br)The objective of this paper is to review the existing literature regarding the advantages and disadvantages that different weaning practices have on the stress responses and productivity of water buffalo in different breeding systems. On farms where water buffalo...

摘要:Abstract(#br)Knowledge of plant breeding systems may be critical to facilitate recovery of species considered at risk. Gesneria pauciflora is a threatened, rupiculous, and riverine species with floral-traits that suggest a hummingbird-pollination system. Because these habitat-pol...

摘要:This study configures a first report regarding the variability of meat quality of locally adapted Pantaneiro sheep depending on different physiological stages and breeding systems. Pantaneiro sheep are raised in Brazil under a tropical wetland ecosystem denominated Pantanal. Twen...

摘要:Pentadesma butyracea Sabine, a rain forest food tree species, plays a vital role in the socio-economic livelihood of some West African rural communities due to its various products. However, its scattered populations are threatened in Benin. Defining appropriate conservation...

摘要:Abstract(#br)The study of breeding systems explores relationships between mating behaviour and parental care. Recent findings have shown that in many birds, fishes, anurans, and insects, females play a more active role than previously thought, by engaging in mate choice, mating w...

摘要:Abstract(#br)The breeding systems of three species of the lichen-forming fungal genus Cladonia were investigated. Cladonia floerkeana , Cladonia galindezii , and Cladonia portentosa were selected due to their contrasting ecologies and reproductive strategies, and because they b...
