| 1 | Prognostic factors and time-related changes influence results of colorectal liver metastases surgical treatment:A single-center analysis显示文摘AIM:To analyze the prognostic factors involved in survival and cancer recurrence in patients undergoing surgical treatment for colorectal liver metastases(CLM) and to describe the effects of time-related changes on survival and recurrence in these patients.METHODS:From January 1994 to January 2006,236 patients with CLM underwent surgery with the aim of performing curative resection of neoplastic disease at our institution and 189(80%) of these patients underwent resection of CLM with curative intention.Preoperative,intraoperative and postoperative data,including primary tumor and CLM pathology results,were retrospectively reviewed.Patients were divided into two time periods:a first period from January 1994 to January 2000(n = 93),and a second period from February 2000 to January 2006(n = 143).RESULTS:Global survival at 1,3 and 5 years in patients undergoing hepatic resection was 91%,54% and 47%,respectively.Patients with preoperative extrahepatic disease,carcinoembryonic antigen(CEA) levels over 20 ng/dL,more than four nodules or extrahepatic invasion at pathological analysis had worse survival.Tumor recurrence rate at 1 year was 48.3%,being more frequent in patients with preoperative and pathological extrahepatic disease and CEA levels over 20 ng/dL.Although patients in the second time period had more adverse prognostic factors,no differences in overall survival and recurrence were observed between the two periods.CONCLUSION:Despite advances in surgical technique and better adjuvant treatments and preoperative imaging,careful patient staging and selection is crucial to continue offering a chance of cure to patients with CLM. | Josep Martí María Marta Modolo Josep Fuster Jaume Comas Rebeca Cosa Joana Ferrer Victor Molina Juan Romero Constantino Fondevila Ramón Charco Juan Carlos García-Valdecasas | 2009 | World Journal of Gastroenterology2009，15，21： | 9 |

| 3 | Age structure of a lizard along an elevational gradient reveals nonlinear lifespan patterns with altitude显示文摘Lifespan is one of the main components of life history.Shorter lifespans can be expected in marginal habitats.However,in the case of ectotherms,lifespan typically increases with altitude,even though temperature-one of the main factors to determine ectotherms'life history-declines with elevation.This pattern can be explained by the fact that a shorter activity time favors survival.In this study,we analyzed how lifespan and other life-history traits of the lizard Psammodromus algirus vary along a 2,200 m elevational gradient in Sierra Nevada(SE Spain).Populations at inter-mediate altitudes(1,200-1,700 m),corresponding to the optimal habitat for this species,had the shortest lifespans,whereas populations inhabiting marginal habitats(at both low and at high altitudes)lived longest.Therefore,this lizard did not follow the typical pattern of ectotherms,as it also lived longer at the lower limit of its distribution,nor did it show a longer lifespan in areas with optimal habitats.These results might be explained by a complex combination of different gradients along the mountain,namely that activity time decreases with altitude whereas food availability increases.This could explain why lifespan was maximum at both high(limited activity time)and low(limited food availability)altitudes,resulting in similar lifespans in areas with contrasting environmental conditions.Our findings also indicated that reproductive investment and body condition increase with elevation,suggesting that alpine populations are locally adapted. | Mar Comas Senda Reguera Francisco JZamora-Camacho Gregorio Moreno-Rueda | 2020 | Current Zoology2020，66，4： | 0 |
| 4 | Morphological determinants of jumping performance in the Iberian green frog显示文摘Predation is one of the main selective forces in nature, frequently selecting potential prey for developing escape strategies. Escape ability is typically influenced by several morphological parameters, such as morphology of the locomotor appendices, muscular capacity, body mass, or fluctuating asymmetry, and may differ between sexes and age classes. In this study, we tested the relationship among these variables and jumping performance in 712 Iberian green frogs Pelophylax perezi from an urban population. The results suggest that the main determinant of jumping capacity was body size (explaining 48% of variance). Larger frogs jumped farther, but jumping performance reached an asymptote for the largest frogs. Once controlled by structural body size, the heaviest frogs jumped shorter distances, suggesting a trade-off between fat storage and jumping performance. Relative hind limb length also determined a small but significant percentage of variance (2.4%) in jumping performance-that is, the longer the hind limbs, the greater the jumping capacity. Juveniles had relatively shorter and less muscular hind limbs than adults (for a given body size), and their jumping performance was poorer. In our study population, the hind limbs of the frogs were very symmetrical, and we found no effect of fluctuating asymmetry on jumping performance. Therefore, our study provides evidence that jumping performance in frogs is not only affected by body size, but also by body mass and hind limb length, and differ between age classes. | Gregorio Moreno-Rueda Abelardo Requeinia-Blaimco Francisco J.Zamora-Camacho Mar Comas Guillem Pascual | 2020 | Current Zoology2020，66，4： | 0 |
| 5 | Habitat-dependent breeding biology of the Blue Tit(Cyanistes caeruleus)across a continuous and heterogeneous Mediterranean woodland显示文摘Mediterranean woodland environments are characterised by high spatial and temporal heterogeneity,which means the inhabiting species face a wide variety of selective pressures.Species may respond differently to habitat heterogeneity and so distinct eco-evolutionary scenarios may be responsible for the inter-habitat variability in reproductive strategies observed in certain species.The inter-forest variability of some reproductive traits in passerines has been examined by comparing forest patches or separated fragments.However,there is still little information regarding how such highly mobile animals adjust their breeding performance across continuous and heterogeneous woodlands.Here we studied the reproductive performance of a population of Blue Tits(Cyanistes caeruleus) in an area of continuous Mediterranean woodland that included two mountain slopes and four different types of forest,ranging from deciduous oak forests to perennial non-oak forests.We studied the habitat heterogeneity and inter-forest phenotypic variation in terms of reproductive performance and adult and nestling biometry,besides also exploring the effects of ectoparasites on Blue Tit reproduction.Eggs were laid earliest in deciduous Pyrenean Oak(Quercus pyrenaica) forests,while clutch size and the number of fledglings were highest in the humid Pyrenean Oak forest,which had the greatest tree coverage and most humid climate,and lowest in the coniferous Scots Pine(Pinus sylvestris) forest.There were no inter-forest differences in hatching(percentage of nests with at least one egg hatched) and fledging(percentage of nests in which at least one nestling fledged)success.Similarly,there were no inter-forest differences in adult and nestling biometry,but adults that raised more fledglings had a lower body mass,while males whose females laid larger clutches had smaller tarsi.Most ectoparasites did not affect Blue Tit reproduction,although Culicoides had a negative impact on nestling body mass.These results suggest that Blue Tits can adjust their reproductive effort to the forest where they breed even across a very small spatial scale.Different eco-evolutionary scenarios,such as phenotypic plasticity or genetic structuring and local adaptation,might explain the phenotypic differentiation in the reproductive strategies observed over small areas in woodlands. | Jorge Garrido-Bautista Carmen Hernandez-Ruiz Jose Luis Ros-Santaella Eliana Pintus Nicola Bernardo Mar Comas Gregorio Moreno-Rueda | 2023 | Avian Research2023，14，3： | 0 |
| 6 | Within-brood body size and immunological differences in Blue Tit(Cyanistes caeruleus)nestlings relative to ectoparasitism显示文摘Several ectoparasites parasitise nestlings decreasing their body condition,growth and survival.To minimise any loss of fitness due to ectoparasites,birds have developed a wide variety of defence mechanisms,potentially including hatching asynchrony.According to the Tasty Chick Hypothesis(TCH),the cost of parasitism would be reduced if ectoparasites tend to eat on less immunocompetent nestlings,typically the last-hatched chick in asynchronously hatched broods,as they are in poor body condition.Two predictions of the TCH are that immune capacity is lower in smaller nestlings than in larger ones and that parasites should provoke a more negative effect on smaller nestlings.Here,we test these predictions in a population of Blue Tits(Cyanistes caeruleus)whose broods are parasitised by Hen Fleas(Ceratophyllus gallinae)and Blowflies(Protocalliphora azurea).We recorded the presence of both ectoparasites and analysed the immunocompetence(number of leucocytes per 10,000 erythrocytes and cutaneous immune response to phytohaemagglutinin)and body condition of smaller and larger nestlings within individual broods.The leucocyte count was higher in smaller nestlings than in larger ones,whereas the cutaneous immune response did not differ between smaller and larger nestlings.Smaller nestlings,but not larger nestlings,had lower body mass when fleas were present.Blowflies,by contrast,had no detectable negative effect on nestlings.Overall,our findings provide partial support to the TCH.Lower immune capacity in smaller nestlings than in larger ones was not supported,but Hen Fleas seemed to negatively impact on smaller nestlings more than on larger ones. | Jorge Garrido-Bautista Antonio Soria Cristina E.Trenzado Amalia Pérez-Jiménez Eliana Pintus José Luis Ros-Santaella Nicola Bernardo Mar Comas Stanislav Kolencík Gregorio Moreno-Rueda | 2022 | Avian Research2022，13，3： | 0 |
