how do seemingly non vagile clades accomplish trans marine dispersal trait and dispersal evolution in the landfowl aves galliformes
Proceedings of The Royal Society B: Biological Sciences, 2017Co-Authors: Peter A Hosner, Joe Tobias, Edward L Braun, Rebecca T KimballAbstract:Dispersal ability is a key factor in determining insular distributions and island community composition, yet non-vagile terrestrial organisms widely occur on oceanic islands. The landfowl (pheasants, partridges, grouse, turkeys, quails and relatives) are generally poor dispersers, but the Old World quail (Coturnix) are a notable exception. These birds evolved small body sizes and high-aspect-ratio wing shapes, and hence are capable of trans-continental migrations and trans-oceanic colonization. Two monotypic partridge genera, Margaroperdix of Madagascar and Anurophasis of alpine New Guinea, may represent additional examples of trans-marine dispersal in landfowl, but their body size and wing shape are typical of poorly dispersive continental species. Here, we estimate historical relationships of quail and their relatives using phylogenomics, and infer body size and wing shape evolution in relation to trans-marine dispersal events. Our results show that Margaroperdix and Anurophasis are nested within the Coturnix quail, and are each 'island giants' that independently evolved from dispersive, Coturnix-like ancestral populations that colonized and were subsequently isolated on Madagascar and New Guinea. This evolutionary cycle of gain and loss of dispersal ability, coupled with extinction of dispersive taxa, can result in the false appearance that non-vagile taxa somehow underwent rare oceanic dispersal.

reducao dos niveis de proteina e suplementacao aminoacidica em racoes para codornas europeias Coturnix Coturnix Coturnix
Revista Brasileira De Zootecnia, 2006Co-Authors: Edson Lindolfo Da Silva, Jose Humberto Vilar Da Silva, Jose Jordao Filho, Marcelo Luis Gomes Ribeiro, Fernando Guilherme Perazzo Costa, Paulo Borges RodriguesAbstract:The effects of feeding nine nutrition plans (NP) on the performance of 576 quails, allotted to a completely randomized design with nine treatments of four replicates of 16 birds, were evaluated in this trial. The following NP were analyzed from 1 to 21 days of age: NP1 = 28% of crude protein (CP), 1.5% lysine (L) and 1.1% methionine + cystine (MC) from 1 to 21 days and 24%CP, 1.3%L and 0.9% MC from 22 to 42 days (control); NP2 = 25.2% CP, 1.23% L and 0.83% MC from 1 to 21 days and of 21.6% CP, 1.0% L and 0.74% MC from 22 to 42 days; NP3 = 22.4% CP, 0.71% MC from 1 to 21 days and 1.2% L and 19.2% CP, 0.64% MC and 0.95% L from 22 to 42 days; NP4 = NP2+L; NP5 = NP3+L; NP6 = NP2+MC; NP7 = NP3+MC; NP8 = NP2+L+MC; and NP9 = NP3+L+MC. The diet supplementation from NP4 to NP9 with L, MC or L+MC aimed to provide values of L and MC similar to NP1. Diets (2,900 kcal ME/kg ) and water were fed ad libitum in both phases. From 1 to 21 days, decreasing dietary crude protein levels from 28 to 22.4% also reduced intake, body weight, weight gain, but did not affect feed conversion. The dietary supplementation with MC increased bird performance. The recommended level of L (1.5%) in a deficient diet in CP (19.2%) and MC (0.71%) decreased quail growth from 1 to 21 days of age. However, meeting the MC requirements decreased dietary CP levels from 28 to 22.4% and from 24 to 19.2%, respectively, for quails from 1 to 21 and 22 to 42 days of age, independent of the lysine supplementation.

Revista Brasileira De Zootecnia, 2006Co-Authors: Edson Lindolfo Da Silva, Jose Humberto Vilar Da Silva, Jose Jordao Filho, Marcelo Luis Gomes Ribeiro, Fernando Guilherme Perazzo Costa, Paulo Borges RodriguesAbstract:O experimento foi realizado objetivando-se avaliar o efeito de nove planos de nutricao (PN) sobre o desempenho de um lote misto de 576 codornas, distribuido em delineamento experimental inteiramente ao acaso, com nove tratamentos e quatro repeticoes de 16 aves. Nas fases de 1 a 21 dias de idade, os PN foram: PN1 = 28% de proteina bruta (PB), 1,5% lisina (L) e 1,1% de metionina+cistina (MC) de 1 a 21 dias e 24%PB, 1,3%L e 0,9%MC de 22 a 42 dias (controle); PN2 = 25,2% PB, 1,23% L e 0,83% MC de 1 a 21 dias e de 21,6% PB, 1,0% L e 0,74% MC de 22 a 42 dias; PN3 = 22,4% PB, 0,71% MC de 1 a 21 dias e 1,2% L e 19,2% PB, 0,64% MC e 0,95% L de 22 a 42 dias; PN4 = PN2+L; PN5 = PN3+L; PN6 = PN2+MC; PN7 = PN3+MC; PN8 = PN2+L+MC; e PN9 = PN3+L+MC. A suplementacao da racao do PN4 ao PN9 com L, MC ou L+MC foi realizada para proporcionar valores de L e de MC semelhantes aos do PN1. As racoes nas duas fases continham 2.900 kcal EM/kg e, como a agua, foram oferecidas a vontade. Na fase de 1 a 21 dias, a reducao da proteina de 28 para 22,4% reduziu o consumo, o peso vivo e o ganho de peso, mas nao afetou a conversao alimentar. A suplementacao da dieta com MC melhorou o desempenho das aves. O uso do nivel de L recomendado (1,5%) em racao deficiente em PB (19,2%) e em MC (0,71%) afetou negativamente o crescimento de codornas de 1 a 21 dias de idade. Ao contrario, o atendimento da exigencia em MC permitiu a reducao da PB de 28 para 22,4% e de 24 para 19,2%, respectivamente, de 1 a 21 e de 22 a 42 dias, independentemente da suplementacao de lisina.

metabolizable energy of feedstuffs determined in japanese quails Coturnix Coturnix japonica
Revista Brasileira De Zootecnia, 2003Co-Authors: Jose Humberto Vilar Da Silva, Edson Lindolfo Da Silva, Jose Jordao Filho, Marcelo Luis Gomes Ribeiro, Fernando Guilherme Perazzo Costa, Marinalva Barbosa Da Silva, Wilson Moreira DutraAbstract:The experiment one was carried out to determine apparent metabolizable energy (AME) and nitrogen-corrected ME (AMEn) of nine feedstuffs in Japanese quails. The objective of the experiment two was to compare diets formulated with AMEn of corn and soybean meal, usually fed to broilers and laying hens, with diets formulated with AMEn determined in growing (22 days of age) and adult quails (65 days of age). In the experiment one, 400 growing quails were fed a basal diet (BD) and nine test diets (70% BD + 30% feedstuffs test), with a total of ten diets with four replicates of ten birds each. In the experiment two, 160 European quails were randomized allotted to three treatments, with twelve replicates of five birds, and fed during three periods of fifteen days. The AME and AMEn values (kcal/kg) for vegetal feedstuffs were: 3,340 and 3,354 for corn, 2,718 and 2,456 for soybean meal, 3,453 and 3,084 for integral soybean extruded, 1,624 and 1,593 for wheat bran, 4,558 and 3,992 for corn gluten meal, 3,329 and 3,378 for cassava flour and 1,238 and 1,223 to integral mesquite pods meal. The animal feedstuffs had 2,874 and 2,453 for fish meal and 3,090 and 2,791 for poultry meal. The AMEn of corn and soybean meal estimated for quail did not improve feed intake, egg production, egg weight and feed egg mass ratio, supporting the validity of use of energy those ingredients obtained with broiler and laying hens for formulated quail diets.
