ABSTRACT Biodiversity research has advanced by testing expectations of ecological and evolutionary hypotheses through the linking of large-scale genetic, distributional, and trait datasets. The rise of molecular systematics over the past 30 years has resulted in a wealth of DNA sequences from around the globe. Yet, advances in molecular systematics also have created taxonomic instability, as new estimates of evolutionary relationships and interpretations of species limits have required widespread scientific name changes. Taxonomic instability, colloquially “splits, lumps, and shuffles,” presents logistical challenges to large-scale biodiversity research because (1) the same species or sets of populations may be listed under different names in different data sources, or (2) the same name may apply to different sets of populations representing different taxonomic concepts. Consequently, distributional and trait data are often difficult to link directly to primary DNA sequence data without extensive and time-consuming curation. Here, we present RANT: Reconciliation of Avian NCBI Taxonomy. RANT applies taxonomic reconciliation to standardize avian taxon names in use in NCBI GenBank, a primary source of genetic data, to a widely used and regularly updated avian taxonomy: eBird/Clements. Of 14,341 avian species/subspecies names in GenBank, 11,031 directly matched an eBird/Clements; these link to more than 6 million nucleotide sequences. For the remaining unmatched avian names in GenBank, we used Avibase's system of taxonomic concepts, taxonomic descriptions in Cornell's Birds of the World, and DNA sequence metadata to identify corresponding eBird/Clements names. Reconciled names linked to more than 600,000 nucleotide sequences, ∼9% of all avian sequences on GenBank. Nearly 10% of eBird/Clements names had nucleotide sequences listed under 2 or more GenBank names. Our taxonomic reconciliation is a first step towards rigorous and open-source curation of avian GenBank sequences and is available at GitHub, where it can be updated to correspond to future annual eBird/Clements taxonomic updates. LAY SUMMARY 23% of avian names on GenBank do not match eBird/Clements, a widely used standardized avian taxonomy. More than 600,000 nucleotide sequences on GenBank are associated with names that do not match eBird/Clements. 10% of eBird/Clements names have nucleotide sequences listed under multiple GenBank names. We provide an open-source taxonomic reconciliation to mitigate difficulties associated with non-standardized name use for GenBank sequences. RESUMEN La investigación sobre biodiversidad ha avanzado al evaluar las expectativas de las hipótesis ecológicas y evolutivas a través de la vinculación de bases de datos genéticos, de distribución y de rasgos a gran escala.

生物多样性研究通过连接大规模的遗传、分布和性状数据集来测试生态和进化假设的期望,从而取得了进展。在过去的30年里,分子系统学的兴起带来了全球范围内丰富的DNA序列。然而,分子系统学的进步也造成了分类学的不稳定性,因为对进化关系的新估计和物种界限的解释需要广泛的学名更改。分类学的不稳定性,通俗地说就是“分裂、块状和混乱”,给大规模生物多样性研究带来了后勤方面的挑战,因为(1)相同的物种或种群集可能在不同的数据源中以不同的名称列出,或者(2)相同的名称可能适用于代表不同分类概念的不同种群集。因此,如果没有广泛和耗时的管理,分布和性状数据通常很难直接与原始DNA序列数据联系起来。在此,我们提出了RANT:鸟类NCBI分类的调和。RANT采用分类协调的方法,对广泛使用并定期更新的鸟类分类系统eBird/ elements中NCBI GenBank(遗传数据的主要来源)中使用的鸟类分类单元名称进行标准化。在GenBank中的14,341个鸟类物种/亚种名称中,有11,031个与eBird/Clements直接匹配;这些链接到超过600万个核苷酸序列。对于GenBank中剩余的未匹配的鸟类名称,我们使用Avibase的分类概念系统、Cornell’s Birds of the World中的分类描述和DNA序列元数据来识别相应的eBird/ elements名称。与60多万个核苷酸序列相关联的名称核对,约占GenBank上所有鸟类序列的9%。近10%的eBird/Clements名称的核苷酸序列在2个或更多的GenBank名称中列出。我们的分类调整是朝着严格和开源的鸟类基因库序列管理迈出的第一步,可以在GitHub上获得,在那里它可以更新,以对应未来的年度eBird/ elements分类更新。GenBank上23%的鸟类名称与广泛使用的标准化鸟类分类eBird/Clements不匹配。GenBank上超过60万个核苷酸序列的名称与eBird/Clements不匹配。10%的eBird/Clements名称包含多个GenBank名称下列出的核苷酸序列。我们提供了一个开源的分类调节,以减轻与GenBank序列的非标准化名称使用相关的困难。RESUMEN La investigación sobre biodiversidad .在生物多样性方面,所有的评价都是有预期的,如:(hipótesis ecológicas)通过进化和遗传变异,如:(vinculación)通过遗传变异,如(distribución)通过遗传变异,如(gran escala)。El auge de la sistemática molecular enlos últimos 30 años ha dado como resultado una gran cantidad de secuencias de de de El mundo。在过去的十年中,关于分子遗传变异的研究进展在sistemática分子遗传变异的研究进展在不确定遗传变异的研究进展taxonómica,关于遗传变异的研究进展在解释遗传变异的研究进展límites,关于遗传变异的研究进展在遗传变异的研究进展在científicos。La inestabilidad taxonómica, colquialmente llamada“divisiones, agrupamientos y reorganizacones”,提出desafíos logísticos para La investigación de La biodiversidad a gran escala porque (1) as mismas species of conjuntos de poblaciones (1) as mismas species of conjuntos de poblaciones (2) el mismo nombre puede应用(1)不同conjuntos de poblaciones代表不同的概念taxonómicos。连续地,将数据存储在distribución上,并将菜单存储在difíciles上,将数据存储在主要位置上,将数据存储在ADN上,将数据存储在curación上,将数据存储在扩展位置上。Aquí,现发言:reconciliación de la taxonomía国家信息中心Información Biotecnológica (CNIB)。该报告的主要内容有:1 .应用程序:reconciliación taxonómica参考标准的数据来源:cunib的基因银行,1 .参考标准的数据来源:cunib的基因银行,1 .参考标准的数据来源:taxonomía基因资源的扩大利用和实际利用:periódicamente参考数据来源:cunib / element。在GenBank中检索了14.341个物种/亚种,在bird / elements中检索了11.031个物种/亚种;Estos se vinculan a más de 600万de secuencias de nucleótidos。Para los restantes nombres de aves no conincides en GenBank, utilizamos el sistema de conceptos taxonómicos de Avibase, descripciones taxonómicas en aves del Mundo de Cornell y metadatos de secuencias de ADN Para identiidenties nombres correspondenes de bird / elements。Los nombres reconciliados vincularon为más de 600.000个secuencias de nucleótidos,约占今天secuencias de aves en GenBank的9%。Casi - el - 10% de de de bird / elements的名称,例如:nucleótidos enumeradas和más nombres en GenBank。 我们的分类协调是GenBank鸟类序列严格开源管理的第一步,可以在GitHub上获得,在那里你可以更新它,以匹配eBird/Clements未来的年度分类更新。

ABSTRACT The Baltimore–Bullock's Oriole hybrid zone is one of the best-studied avian hybrid zones in North America, yet our understanding of the causes of selection against hybrids remains poor. We examine if endohelminth parasites may cause selection against hybrid orioles but found no evidence for this hypothesis. Of the 139 male orioles we examined, 43 individuals contained endohelminth parasites from at least 1 of these groups: Cestoda, Acanthocephala, or Nematoda. Across the hybrid zone, Baltimore Orioles (Icterus galbula) and Bullock's Orioles (I. bullockii) differed in their parasite communities, such that Baltimore Orioles frequently contained both Acanthocephala and Cestoda parasites whereas Bullock's Orioles primarily contained Cestoda parasites. Despite these differences in parasite communities between parental species, the frequency of hybrid orioles with parasites was similar to parentals, suggesting that hybrids were as susceptible to endohelminth parasites as parentals. Using a subset of 99 adult male orioles, we explored how parasites may be associated with the expression of orange carotenoid-based plumage in hybrids and parentals. Associations between carotenoid-based plumage color and parasites were most strongly expressed in Bullock's Orioles, but patterns were subtle and counterintuitive because individuals with parasites often had more enhanced color measures compared to individuals without parasites. Taken together, these data suggest that endohelminth parasites impose little fitness costs to male orioles on the breeding grounds and likely do not cause selection against hybrids. LAY SUMMARY Baltimore and Bullock's orioles regularly hybridize where their breeding ranges overlap in the Great Plains, USA. Despite years of study, we have a poor understanding of why hybrids perform poorly. We examined if hybrid orioles might suffer from internal parasitic worms, as hybrids may have compromised immune systems making them more susceptible to parasites. We examined for lethal effects of parasites inferred through different ratios of infected vs. uninfected orioles and we examined non-lethal effects inferred through the quality of their orange plumage color. Our findings suggest that while Baltimore and Bullock's orioles differ in their parasite communities, internal parasitic worms present little to no costs to hybrid orioles. RESUMEN La zona híbrida de Icterus galbula-I. bullockii es una de las zonas híbridas aviares mejor estudiadas en América del Norte, pero nuestra comprensión de las causas de la selección contra los híbridos sigue siendo deficiente.

巴尔的摩-布洛克黄鹂杂交带是北美研究最深入的鸟类杂交带之一,但我们对杂交选择的原因仍然知之甚少。我们研究了内生寄生虫是否可能导致对杂交黄鹂的选择,但没有发现这一假设的证据。在我们检查的139只雄性黄鹂中,有43只含有至少一种来自这些类群的内皮寄生虫:Cestoda, Acanthocephala或Nematoda。在整个杂交带,巴尔的摩金莺(Icterus galbula)和布洛克金莺(I. bullockii)的寄生虫群落存在差异,巴尔的摩金莺经常同时含有棘头虫和Cestoda寄生虫,而布洛克金莺主要含有Cestoda寄生虫。尽管亲本物种之间的寄生虫群落存在这些差异,但携带寄生虫的杂交种黄鹂的频率与亲本相似,这表明杂交种与亲本一样容易感染内皮寄生虫。利用99只成年雄性黄鹂的一个亚群,我们探索了寄生虫如何与杂交和亲本中橙色类胡萝卜素羽毛的表达相关。以类胡萝卜素为基础的羽毛颜色和寄生虫之间的联系在布洛克黄鹂身上得到了最强烈的表达,但这种联系是微妙的,违反直觉的,因为与没有寄生虫的个体相比,有寄生虫的个体通常有更强的颜色测量。综上所述,这些数据表明,在繁殖地,内生寄生虫对雄性黄鹂的适应性成本很小,而且可能不会导致对杂交物种的选择。在美国大平原上,巴尔的摩和布洛克的黄鹂经常在它们的繁殖范围重叠的地方杂交。尽管经过多年的研究,我们对混血儿表现不佳的原因了解甚少。我们研究了杂交黄鹂是否可能患有体内寄生虫,因为杂交黄鹂的免疫系统可能受损,使它们更容易受到寄生虫的感染。我们通过感染与未感染的黄鹂的不同比例来检测寄生虫的致死效应,并通过其橙色羽毛颜色的质量来检测非致死效应。我们的研究结果表明,虽然巴尔的摩和布洛克的黄鹂的寄生虫群落不同,但内部寄生蠕虫对杂交黄鹂来说几乎没有成本。resume La zona híbrida de Icterus galbula。bullockii是美国东部地区的主要研究人员,是美国东部地区的主要研究人员,是美国东部地区的主要研究人员,是美国东部地区的主要研究人员comprensión,是美国东部地区的主要研究人员,是墨西哥东部地区的主要研究人员,是墨西哥东部地区的主要研究人员,是墨西哥东部地区的主要研究人员,是墨西哥东部地区的主要研究人员,是墨西哥东部地区的主要研究人员。Examinamos si los parásitos endo-helmínticos pueden causar selección contra oropsamndola híbridas, pero no encontramos evidence para esta hipótesis。研究结果显示,139个个体的健康状况得到了改善,43个个体的健康状况得到了改善,其中包括线虫、棘头目和线虫。A lo largo de la zona híbrida, los individuos de Icterus galbula I. bullockii difiereron en sus comcomades de parásitos, de modo que Icterus galbula recentemente albergó parásitos de Acanthocephala y Cestoda, mientras que I. bullockii albergó principalmente parásitos de Cestoda。pesar de是diferencias在拉斯维加斯comunidades de parasitos之间especies父母,la frecuencia de oropendolas hibridas con parasitos fue类似la de los父母,lo, sugiere,洛杉矶hibridos fueron tan易感者一个洛杉矶parasitos endo-helminticos科莫洛杉矶父母。Usando在1999年的一次会议上发表了一份关于成年男子的报告,题为“探索cómo los parásitos”,“探索cómo los parásitos”,“探索expresión”,“探索”,“探索”,“探索”,“探索”,“探索”,“探索”,“探索”,“探索”,“探索”,“探索”。Las associaciones entre el color del plumaje basado en carotenides by los parásitos se expresaron con mayor fuerza en I. bullockii, pero los patrones fueron sutiles by contrarios a la intuición, porque los individuos con parásitos a menudo tuvieron medidas de color más realzadas en comparación con los individuos sin parásitos。Tomados en conjunto, estos datos sugieren que los parásitos endo-helmínticos imponen pequeños costos de adecuación和los machos de oropsamndola en las áreas生殖器官可能无因selección contra los híbridos。

ABSTRACT Savannah Sparrows (Passerculus sandwichensis) and Tree Swallows (Tachycineta bicolor) breed and forage in the same habitat on Kent Island, a boreal island in the Bay of Fundy, New Brunswick, but respond differently to the same weather conditions. The 2 passerines are similar in body size but because Tree Swallows depend upon small flying insects captured on the wing, they may be more sensitive to weather than Savannah Sparrows, which forage on insects and seeds on the ground and in shrubs and trees. To compare how reproductive success in the 2 species was affected by weather conditions, we took advantage of an 18-year dataset and used a model-building approach that controlled for year, adult sex and age, and field where they nested. We focused on 3 measures of reproductive success (hatching success, fledging success, and nestling condition) and different time periods (3- to 18-day time windows) before hatching or fledging. The responses of the 2 species differed in magnitude and direction. In Tree Swallows, adding weather variables to the basic model increased the explanatory power of fixed effects by 19.1%, illustrating the swallows' sensitivity to weather. In contrast, in Savannah Sparrows, the addition of weather variables only increased the model's explanatory power by 0.4% and the proportion of variation attributed to fixed factors by only 1.5%, which reflected the species' hardiness in the face of inclement weather. Our results suggest that how a bird species forages and the nature of its prey may influence its sensitivity to weather and indicate that increased rainfall, strong winds and other events associated with climate change may affect Tree Swallows and other aerial insectivores more than ground-foraging birds such as Savannah Sparrows. LAY SUMMARY Nestling Savannah Sparrows and Tree Swallows, which occur in the same habitat on Kent Island, New Brunswick, Canada, were affected differently by the same weather conditions, likely because of differences in the way their parents forage for food. Nestling Tree Swallows, whose parents depend on capturing small insects in flight, were highly sensitive to rain and wind, whereas weather had relatively little effect on nestling Savannah Sparrows, which forage mainly on the ground. As a consequence, Tree Swallows and other aerial insectivores may be especially vulnerable to climate change.

在新不伦瑞克省芬迪湾北部岛屿肯特岛上,大草原麻雀(Passerculus sandwhensis)和树燕(Tachycineta bicolor)在同一栖息地繁殖和觅食,但对相同天气条件的反应不同。这两种雀形目动物的体型相似,但由于树燕以捕获的小飞虫为食,因此它们可能比萨凡纳麻雀对天气更敏感。萨凡纳麻雀以地上、灌木和树上的昆虫和种子为食。为了比较这两个物种的繁殖成功率如何受到天气条件的影响,我们利用了一个18年的数据集,并使用了一种模型构建方法,该方法控制了年份、成虫的性别和年龄以及它们筑巢的地点。我们重点研究了3种繁殖成功指标(孵化成功、羽化成功和雏鸟状况)和不同的孵化或羽化时间(3 ~ 18天时间窗)。两种植物的响应在大小和方向上存在差异。在树燕中,在基本模型中加入天气变量,固定效应的解释力提高了19.1%,说明了树燕对天气的敏感性。相比之下,在萨凡纳麻雀中,天气变量的加入仅使模型的解释能力提高了0.4%,归因于固定因素的变异比例仅提高了1.5%,这反映了该物种面对恶劣天气的适应力。我们的研究结果表明,鸟类的觅食方式和猎物的性质可能会影响其对天气的敏感性,并表明降雨增加、强风和其他与气候变化相关的事件可能对树燕和其他空中食虫动物的影响大于对地面觅食鸟类(如萨凡纳麻雀)的影响。在加拿大新不伦瑞克省肯特岛的同一个栖息地,雏鸟萨凡纳麻雀和树燕受到相同天气条件的不同影响,可能是因为它们的父母寻找食物的方式不同。树燕的父母依靠捕捉飞行中的小昆虫为生,它们对雨和风非常敏感,而天气对主要在地面觅食的大草原麻雀的影响相对较小。因此,树燕和其他空中食虫动物可能特别容易受到气候变化的影响。RESUMEN Passerculus sandwich is by Tachycineta双色,在不同的条件下,通过不同的营养物质繁殖,在不同的条件下繁殖hábitat在肯特岛,在北方岛,在Bahía de Fundy, New Brunswick。Los dos paseriformes son similares en tamaño下士,pero debido a que T. bicolor dependes de pequeños昆虫voladores capturados en el vuelo, pueden ser más sensibles all climes que P.三明治,que se alimentes de昆虫的semillas en el suelos en Los árboles y arbustos。第1段比较cómo妇女的生殖健康状况与妇女的生殖健康状况有关climáticas,批准妇女的生殖健康状况与妇女的生殖健康状况有关años,利用妇女的生殖健康状况与妇女的生殖健康状况有关construcción,妇女的生殖健康状况与妇女的生殖健康状况有关año,妇女的生殖健康状况与妇女的生殖健康状况有关año,妇女的生殖健康状况与妇女的生殖健康状况有关。两个不同的电子文件(如电子文件和电子文件)和电子文件(如电子文件和电子文件)(如电子文件和电子文件)(如电子文件和电子文件)(如电子文件和电子文件)(如电子文件和电子文件)(如电子文件和电子文件)(如电子文件和电子文件)。最后的反应是,在不同的情况下,以dirección为数量级。在T.双色中,聚合变量climáticas al模型(básico aumentó)表明,该模型对气候变化的影响较低,为19.1%,但对气候变化的敏感性较低。与此相反,En P.三明治,la adición de variables climáticas solo aumentó el粉末的解释性模型模型为0,4%,la proporción de variación属性和因素的模型模型为1,5%,la que refleja la resistance de la especient和las inmencias del clima。都resultados sugieren公式ave形式从事什么una especie se alimenta y la naturaleza de sus声部进入记号含量influir苏sensibilidad al此种e糖苷,el aumento de las precipitaciones洛杉矶vientos要塞和eventos asociados con el: climatico含量afectar t . y二色的一个其它insectivoros aereos马斯是一个拉斯维加斯鸟类,se alimentan en el suelo科莫sandwichensis页。

ABSTRACT The Mallard (Anas platyrhynchos) duck is a ubiquitous and socio-economically important game bird in North America. Despite their generally abundant midcontinent population, Mallards in eastern North America are declining, which may be partially explained by extensive hybridization with human-released domestically derived game-farm Mallards. We investigated the genetic composition of Mallards in the middle and lower Mississippi flyway, key wintering regions for the species. We found that nearly 30% of wild Mallards carried mitochondrial (mtDNA) haplotypes derived from domestic Mallards present in North America, indicating that the individuals had female game-farm Mallard lineage in their past; however, nuclear results identified only 4% of the same sample set as putative hybrids. Recovering 30% of samples with Old World (OW) A mtDNA haplotypes is concordant with general trends across the Mississippi flyway and this percentage was stable across Mallards we sampled a decade apart. The capture and perpetuation of OW A mtDNA haplotypes are likely due to female breeding structure, whereas reversal of the nuclear signal back to wild ancestry is due to sequential backcrossing and lower and/or declining admixture with game-farm Mallards. Future studies of wild ancestry of Mississippi flyway Mallards will benefit from coupling molecular and spatial technology across flyways, seasons, and years to search for potential transitions of Mallard populations with different genetic ancestry, and whether the genetic ancestry is somehow linked to an individual's natal and subsequent breeding location. LAY SUMMARY Mallard ducks are common worldwide but are declining in the Atlantic flyway of eastern North America, a decline that may be influenced by widespread hybridization between genetically wild Mallards and domestic game-farm birds that are released for hunting. We used hunter-harvested birds to investigate possible westward expansion and hybridization rates in the lower Mississippi flyway. Despite recovering 30% of samples possessing game-farm Mallard-derived mitochondrial DNA, only 4% were identified as hybrids across thousands of nuclear loci. Prevalence of game-farm Mallard-derived mitochondrial haplotypes were consistent in Mallards sampled a decade apart, suggesting mitochondrial introgression can be captured and persist within lineages far longer than nuclear DNA. Whereas the prevalence of wild × game-farm Mallard hybrids remains significantly less in the lower Mississippi relative to the Atlantic flyway, continued genetic monitoring and development of management strategies to abate future hybridization will be required. RESUMEN Anas platyrhynchos es un ave de caza ubicua y socio-económicamente importante en América del Norte. A pesar de su población generalmente abundante en el centro del continente, la especie está disminuyendo en el este de América del Norte, lo que puede explicarse en parte por la hibridación extensiva con individuos de A. pla
绿头鸭(Anas platyrhynchos)是一种在北美普遍存在且具有重要社会经济意义的猎禽。尽管大陆中部地区的绿头鸭数量普遍丰富,但北美东部的绿头鸭数量正在下降,部分原因可能是与人类放养的家养野鸭进行了广泛的杂交。本文研究了绿头鸭在密西西比中下游的主要越冬区的遗传组成。研究发现,近30%的野生绿头鸭携带来自北美家养绿头鸭的线粒体(mtDNA)单倍型,表明这些个体过去曾有过雌性野场绿头鸭的血统;然而,核结果只确定了4%的相同样本是假定的杂交种。恢复30%的旧世界(OW) A mtDNA单倍型的样本与整个密西西比飞行路线的总体趋势一致,并且这个百分比在我们间隔十年采样的绿头鸭中是稳定的。OW A mtDNA单倍型的捕获和延续可能是由于雌性的繁殖结构,而核信号的逆转回到野生祖先是由于连续的回交和与农场野鸭的低和/或减少的混合。未来对密西西比飞道绿头鸭野生祖先的研究将受益于跨飞道、季节和年份的分子和空间耦合技术,以寻找具有不同遗传祖先的绿头鸭种群的潜在转变,以及遗传祖先是否以某种方式与个体的出生和随后的繁殖地点有关。绿头鸭在世界范围内都很常见,但在北美东部的大西洋飞行路线上,绿头鸭的数量正在减少,这种减少可能是由于基因野生的绿头鸭与被放归猎场的家禽之间广泛杂交的影响。我们使用狩猎收获的鸟类来调查可能的西向扩张和杂交率在密西西比河下游的飞行路线。尽管回收了30%的带有野鸭线粒体DNA的样本,但只有4%的样本被确定为数千个核位点的杂交品种。在间隔十年的野鸭样本中,野鸭线粒体单倍型的流行率是一致的,这表明线粒体渗入可以被捕获并在世系中持续存在的时间远远超过核DNA。与大西洋迁徙路线相比,在密西西比河下游地区,野生野鸭杂交的流行率明显低于大西洋,因此需要持续的遗传监测和管理策略的发展,以减少未来的杂交。简历Anas platyrhynchos是在美国北部的一个重要的地方。1 .特别报告员población在非洲大陆中心的一般性报告,特别是在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中,特别在非洲大陆中心的一般性报告中明确指出hibridación在非洲大陆中心的广泛个人报告中。对密西西比下游地区,特别是因弗纳达-帕拉拉地区,鸭嘴兽的遗传变异composición的调查。在美国北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥北部的美国,在墨西哥,在墨西哥,在墨西哥,在墨西哥;在禁运中,其结果是,只有联合国4%的核鉴定结果符合联合国的规定。世界经济研究所(VM)研究了一般趋势的研究和密西西比迁徙者的研究,并研究了不同个体间的发展趋势的研究和不同个体间的发展趋势的研究。一种VM可能被描述为一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体,一种结构上的繁殖体。密西西比白颈背蝗个体的遗传变异研究进展beneficiarán遗传变异unión遗传变异tecnología遗传变异空间研究进展与遗传变异研究进展años遗传变异研究进展与遗传变异研究进展从确定的角度看,上升的遗传变异与遗传变异之间的关系与遗传变异与遗传变异之间的关系。
