Recent empirical and theoretical studies suggest that personality and locomotory performance traits linked to dispersal abilities are crucial components of the dispersal syndromes,and that they can evolve during range expansions and colonization processes.Island colonization is one of the best characterized processes in dispersal biogeography,and its implication in the evolution of phenotypic traits has been investigated over a wide range of temporal scales.However,the effect of island colonization on personality and performance traits of natural populations,and how these traits could drive island colonization,has been little explored.Noteworthy,no studies have addressed these processes in the context of late Pleistocene range expansions.Here,we investigated the contribution of island colonization triggered by postglacial range expansions to intraspecific variation in personality and locomotory performance traits.We compared boldness,exploration,jumping performance,and stickiness abilities in populations from 3 equidistant areas of the Tyrrhenian tree frog Hyla sarda,2 from the main island(Corsica Island),and 1 from the recently colonized island of Elba.Individuals from Elba were significantly bolder than individuals from Corsica,as they emerged sooner from a shelter(P=0.028),while individuals from Corsica showed markedly higher jumping and stickiness performance(both P<0.001),resulting as more performing than those of Elba.We discuss these results in the context of the major microevolutionary processes at play during range expansion,including selection,spatial sorting,founder effects,and their possible interaction with local adaptation processes.

Oxidative stress is a key physiological mechanism underlying life-history tradeoffs. Here, I use meta-analytic techniques to test whether sexual differences in oxidative balance are common in vertebrates and to identify which factors are associated with such differences. The dataset included 732 effect size estimates from 100 articles (82 species). Larger unsigned effect size (meaning larger sexual differences in a given marker) occurred in: reptiles and fish; those species that do not provide parental care; and oviparous species. Estimates of signed effect size (positive values meaning higher oxidative stress in males) indicated that females were less resistant to oxidative stress than males in: reptiles while males and females were similar in fish, birds, and mammals; those species that do not provide parental care; and oviparous species. There was no evidence for a significant sexual differentiation in oxidative balance in fish, birds, and mammals. Effect size was not associated with: the number of offspring; whether the experimental animals were reproducing or not; biomarker (oxidative damage, non-enzymatic, or enzymatic antioxidant), the species body mass; the strain (wild vs. domestic); or the study environment (wild vs. captivity). Oxidative stress tended to be higher in females than males across most of the tissues analyzed. Levels of residual heterogeneity were high in all models tested. The findings of this meta-analysis indicate that diversification of reproductive strategies might be associated with sexual differences in oxidative balance. This explorative meta-analysis offers a starting platform for future research to investigate the relationship between sex and oxidative balance further.

Redox physiology in animal function:The struggle of living in an oxidant environment

引用

Current Zoology 2010年第6期56卷 687-702页

作者： david costantini Division of Ecology and Evolutionary Biology Faculty of Biomedical and Life SciencesUniversity of Glasgow

A strong focus of ecological research for several decades has been to understand the factors underlying the variationin animal life-histories. In recent times, ecological studies have begun to show that oxidative stress may represent another importantmodulator of competitive trade-offs among fitness traits or of positively integrated patterns of traits. Therefore, incorporatingmechanisms underlying oxidative physiology into evolutionary ecology has the potential to help understand variation inlife-history strategies. In this review, I provide a general overview of oxidative stress physiology, and subsequently focus on topicsthat have been neglected in previous ecological reviews on oxidative stress. Specifically, I introduce and discuss the adaptationsthat animals have evolved to cope with oxidative stress; the environmental stressors that can generate changes in oxidativebalance; the role of reactive species in transduction of environmental stimuli and cell signaling; and the range of hormetic responsesto oxidative

A meta-analysis of the effects of geolocator application on birds

An increasing trend in use of tracking devices such as geolocators is based on the assumption that the information gathered from such devices provides reliable information about the migratory behavior of free-living birds. This underlying assumption is rarely tested, as evidenced by the absence in many studies of controls, in particular treated controls, and so far never with a reasonable statistical power. Published studies have shown reduced survival prospects or delayed breeding in some species, suggesting that there may be reason to doubt that tracking devices provide unbiased information. Therefore, we conducted a meta-analysis of studies applying geolocators to wild birds to determine whether geolocators affected fitness components. Ge-olocators had an overall negative effect on fitness components, in particular survival, and ecological variables. Effect size was larger for aerial foragers than for other species. Moreover the leg band attachment method was more detrimental for birds than the leg-loop backpack harness. A meta-regression model of effect size showed independent negative effects of geolocators on aerial foragers, smaller species, species with smaller migration distances and in studies where geolocators were attached with a ring. These results suggest that geolocator studies should be interpreted with caution, but also raise questions whether it is ethically defensible to use geolocators on aerial foragers or small species without carrying out robust pilot studies.

Many animal species migrate over long distances, but the physiological challenges of migration are poorly understood. It has recently been suggested that increased molecular oxidative damage might be one important challenge for migratory animals. We tested the hypothesis that autumn migration imposes an oxidative challenge to bats by comparing values of 4 blood-based markers of oxidative status (oxidative damage and both enzymatic and nonenzymatic antioxidants) between Nathusius' bats Pipistrellus nathusii that were caught during migration flights with those measured in conspecifics after resting for 18 or 24 h. Experiments were carried out at Pape Ornithological Station in Pape (Latvia) in 2016 and 2017. Our results show that flying bats have a blood oxidative status different from that of resting bats due to higher oxidative damage and different expression of both non enzymatic and enzymatic antioxidants (glutathione peroxidase). The differences in oxidative status markers varied betwee n sampli ng years and were in depende nt from in dividual body con dition or sex. Our work provides evidence that migratory flight might impose acute oxidative stress to bats and that resting helps animals to recover from oxidative damage accrued en route. Our data suggest that migrating bats and birds might share similar strategies of mitigating and recovering from oxidative stress.

Oxidative stress favours herpes virus infection in vertebrates： a meta-analysis

Herpes viruses are responsible for a variety of pathological effects in humans and in both wild and domestic animals. One mechanism that has been proposed to facilitate replication and activity of herpes viruses is oxidative stress (OS). We used meta-analytical techniques to test the hypotheses that (1) herpes virus infection causes OS and (2) supplementation of antioxidants reduces virus load, indicating that replication is favoured by a state of OS. Results based on studies on mammals, including humans, and birds show that (1) OS is indeed increased by herpes virus infection across multiple tissues and species, (2) biomarkers of OS may change differently between tissues, and (3) the effect size does not differ among different virus strains. In addition, the increase of oxidative damage in blood (tissue commonly available in ecological studies) was similar to that in the tissues most sensitive to the herpes virus. Our results also show that administration of antioxidants reduces virus yield, indicating that a condition of OS is favorable for the viral replication. In addition, some antioxidants may be more efficient than others in reducing herpes virus yield. Our results point to a potential mechanism linking herpes virus infection to individual health status.

Carotenoids are fat-soluble pigments synthesised by photosynthetic organisms(Brush,1990).Conversely,animals are incapable of synthesizing carotenoids de novo,and they must obtain them through their diet.However,some animal species are able to make some alterations to the basic chemical structure,converting ingested carotenoids into more oxidized and differently coloured forms(Schiedt,1998).

采用气相色谱法和电子捕获检测技术,对1999和2005年繁育季节结束时在意大利罗马周边地区采集的未能孵化的红隼(Falco tinnunculus)卵进行研究,得出多氯联苯(PCB)、滴滴涕(DDT)及其衍生物和其他有机氯化合物的浓度。结果表明,在所有的PCBs中,同类物153和180所有被测卵中均有检出,且浓度最高。相同鸟巢不同年份收集的卵中含有的PCB同类物类型和数量相似。本研究发现硫矿附近的隼卵中含有非典型性的低氯同类物,该结果有力地支持了地中海和欧洲大陆的成年红隼仅进行短距离迁徙或不迁徙的结论,即暗示着隼卵污染物来自于当地环境。研究还发现同一窝中不同卵中的PCBs类型相似,但浓度却随着产卵的时间顺序延伸而不断降低。

In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to Observatory Science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass X-ray binaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. eXTP will be excellently suited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Science, the eXTP mission is expected to be launched in the mid 2020s.
