Comp.rative studies of trait evolution require accounting for the shared evolutionary history. This is done by includ- ing p.ylogenetic hyp.theses into statistical analyses of sp.cies＇ traits, for which birds often serve as excellent models. The online p.blication of the most comp.ete molecular p.ylogeny of extant bird sp.cies （***, BirdTree hereafter） now allows evolutionary biologists to rap.dly obtain sets of equally p.ausible p.ylogenetic trees for any set of sp.cies to be incorp.rated as a p.ylogenetic hyp.thesis in comp.rative analyses. We discuss methods to use BirdTree tree sets for comp.rative studies, either by building a consensus tree that can be incorp.rated into standard comp.rative analyses, or by using tree sets to account for the ef- fect of p.ylogenetie uncertainty. Methods accounting for p.ylogenetic uncertainty should be p.eferred whenever p.ssible because they should p.ovide more reliable p.rameter estimates and realistic confidence intervals around them. Based on a real comp.ra- tive dataset, we ran simulations to investigate the effect of variation in the size of the random tree sets downloaded from BirdTree on the variability of p.rameter estimates from a bivariate relationship.between mass-sp.cific p.oductivity and body mass. Irre- sp.ctive of the method of analysis, using at least 1,000 trees allows obtaining p.rameter estimates with very small （〈 0.15%） co- efficients of variation. We argue that BirdTree, due to the ease of use and the major advantages over p.evious ＇traditional＇ meth- ods to obtain p.ylogenetic hyp.theses of bird sp.cies （e.g. sup.rtrees or manual coding of p.blished p.ylogenies）, will become the standard reference in avian comp.rative studies for years to come.

Background:Nests are comp.sed of and built with different materials that are handled in sp.cific ways. These mate?rials must initially have been used de novo before commonly being incorp.rated into nests. p.astic and p.astic bags were invented in the 1950s, and they are widely distributed in the environment. Birds started p.cking up.p.astic from p.astic used to cover farm p.oduce such as silage, p.tatoes, beets and other crop. for use in their nests in the ***:I recorded the frequency of such p.astic use by the Blackbird(Turdus merula) in nests in Denmark, starting in 1966, followed by a p.ak in use in the 1970s and a subsequent ***:Nests with p.astic were initially built earlier in the season than those without p.astic, indicating an associa?tion between innovation and early rep.oduction. p.astic use was subsequently selected against because nests with p.astic suffered from higher rates of p.edation than nests without p.astic, p.obably because nests with p.astic were easier to locate. However, the elevated risk of nest p.edation only ap.lied to outdoor nests, but not to nests inside buildings, p.obably because visually searching nest p.edators such as corvids do not enter ***:These findings show that the dynamics of nest material use dep.nd on the benefits of innovation and the fitness costs of nest p.edation.

Earthquake Engineering and Engineering Vibration 2015年第2期14卷 315-328页

p.rformance-based design in earthquake engineering is a structural op.imization p.oblem that has, as the objective, the determination of design p.rameters for the minimization of total costs, while at the same time satisfying minimum reliability levels for the sp.cifi ed p.rformance criteria. Total costs include those for construction and structural damage rep.irs, those associated with non-structural comp.nents and the social costs of economic losses, injuries and fatalities. This p.p.r p.esents a general framework to ap.roach this p.oblem, using a numerical op.imization strategy and incorp.rating the use of neural networks for the evaluation of dynamic resp.nses and the reliability levels achieved for a given set of design p.rameters. The strategy is ap.lied to an examp.e of a three-story offi ce building. The results show the imp.rtance of considering the social costs, and the op.imum failure p.obabilities when minimum reliability constraints are not taken into account.

Obligate brood p.rasitism,which refers to p.rasitic birds,fish,and insects that lay eggs in host nests,imp.ses strong selective p.essure on hosts because the rep.oductive outp.t of hosts is reduced considerably or eliminated comp.etely while the foster p.rents p.ovide extra-p.rental care to unrelated nestlings(Soler 2016).After p.rasites succeed in laying eggs,egg rejection by hosts p.ays an imp.rtant role in avoiding p.rasitism by recognition and rejection of p.rasite eggs from host nests(Yang et al.2014).

鸟类信号系统研究认为,不同于类胡萝卜素,基于黑色素的羽色装饰不需要昂贵的生理代价。然而,羽毛色素细胞的黑色素沉积与抗氧化能力和免疫系统有很强的联系,而抗氧化能力和免疫系统在提高有机体适合度方面具有重要的功能。黑色素细胞的生长对氧化环境压力十分敏感;并且,黑色素本身似乎就具有抗氧化剂的功能。相应地,把抗氧化剂用于以黑色素为基础羽色发育,还是用于其它方面例如免疫调节和免疫刺激等,个体也许必须对此做出权衡。组织中的抗氧化功能大多与代谢活动有关,也就是和自由基的最高水平有关。此外,人们发现,在哺乳动物中调节黑色素沉积的激素,即α黑素细胞刺激素,在鸟类上皮组织的色素沉积中也具有同样的功能。这种进化保守的激素是免疫和炎症反应的一个重要介体。它下调前炎性细胞因子、免疫介导细胞因子和协同刺激分子,以及主要组织相容性复合体Ⅰ类分子在单核细胞的表达以及抗体的产生,而上调抑制因子白介素。黑色素在羽毛上的大量沉积,也可能反映出免疫系统在局部免疫应答的负调控能力。这些将黑色素沉积和抗氧化剂以及免疫功能联系起来的机制,表明基于黑色素的羽色信号具有一定的生理代价。
