Post-fledging survival of individual great tits: the effect of hatching date and fledging mass
2002
Pre-breeeding survival is one of the major sources of individual variation in lifetime reproductive success. However, very little is known about the reasons for differences in survival among individuals during this important phase of the life cycle. Some studies, using local return rates as indices of survival, have shown a relationship between post-fledging survival and fledging date and mass in birds, most of them suggesting directional selection towards heavy masses and early fledging dates. Recent development of capture-recapture models allows the separate estimate of survival and recapture probabilities, as well as the inclusion of individual covariates into the modelling process. We u…
Great tit (Parus major) breeding in fire-prone oak woods: differential effects of post-fire conditions on reproductive stages
2011
Wildfires negatively affect the overall reproductive success of several woodland avian species, but there is scarce information about which stages of the nesting cycle are specifically affected. We conducted a 3-year study to identify the effects of fire on the reproductive parameters of the great tit (Parus major) and the survival of its nests at different stages of the nesting cycle. We recorded the occupancy rate, clutch and brood size, hatching, fledging and nesting success in nest boxes placed on study plots with different post-fire age. By examining the post-fire succession, we analysed the survival of eggs and nestlings under predation risks. As the forest matured after a wildfire, …
Le limitazioni al regime di circolazione e valorizzazione delle azioni e quote, profili civilistici
2022
Il presente contributo propone l'analisi di alcuni strumenti giuridici offerti dall’autonomia privata in ambito societario, in modo da permettere all’imprenditore – in tutte le ipotesi in cui quest’ultimo intenda determinare, prima della sua morte, la successione dell’azienda di famiglia – di pianificare in modo efficace il passaggio generazionale, avvantaggiando o sfavorendo, a seconda dei casi, il trasferimento delle partecipazioni societarie, con il proposito di disinnescare i rischi di disgregazione dell’unità dell’impresa e di conflitti tra i membri della famiglia. This contribution proposes the analysis of some legal instruments offered by private autonomy in the corporate sphere, in …
Relationship between the seed rain and the establishment of vegetation in two areas abandoned after peat harvesting
1987
In this study the number and species composition of diaspores dispersing into two newly abandoned peat harvesting areas in Finland were investigated. In an area abandoned six years earlier a total of 2978 living seeds m−2, representing 18 species, was captured by using water-filled traps during two summers. In a one-year-old succession area the total number of living seeds m−2 was 2241, representing 16 plant species. The soil seed banks were found to be empty of viable seeds. In neither area there appeared to be any relation between number of dispersing seeds and of plant individuals of the same species in the pioneer vegetation. It is suggested that unfavourable conditions on the soil surf…
Methanotrophy induces nitrogen fixation during peatland development
2013
Significance In peatlands, the external sources of nitrogen are mainly atmospheric, but the atmospheric nitrogen deposition alone cannot explain the long-term annual nitrogen accumulation rates to these ecosystems. Because of methodological problems, methane-induced fixation of atmospheric dinitrogen gas has been previously overlooked as an additional nitrogen input mechanism. We found that the activity of methane-oxidizing bacteria provides not only carbon but also nitrogen to peat mosses and, thus, contributes to carbon and nitrogen accumulation in peatlands, which store approximately one-third of the global soil carbon pool. Our results imply that nitrogen fixation in wetlands may be str…
Perfil de habilidades psicológicas en taekwondistas universitarios y su relación con el éxito en competición
2014
Se presenta el perfil de habilidades psicológicas y su poder predictivo sobre el éxito deportivo en taekwondistas universitarios de competición. Para ello se evaluó una muestra representativa de 89 taekwondistas (50 hombres y 39 mujeres) con edades entre 18 y 34 años (M = 22,2; DT = 3,34) que competían en el Campeonato de España Universitario 2011. Se les administró el Inventario Psicológico de Ejecución Deportiva (IPED) y se tomó como variable de éxito deportivo el número de combates ganados durante el campeonato. Los análisis multivariados mostraron diferencias (p < ,05) en relación al género (los hombres informan de mayor auto-confianza, control atencional y afrontamiento negativo) y rec…
Laser Therapy for Infected Sites and Immediate Dental Implants in the Esthetic Zone: A Case Report and Review of Literature
2020
Placement of postextraction dental implants has become a common practice. Here, we reviewed current literature, along with clinical procedures, outcomes, and incidence of complications, associated with immediate implants in infected postextraction sites. The YSGG (yttrium, scandium, gallium, and garnet) laser can significantly reduce the bacterial concentration after extracting a compromised tooth. We treated a 40-year-old woman with a compromised tooth in the esthetic zone, presenting clinical and radiological signs of infection, particularly a periapical periodontitis. The tooth was extracted after administering local anesthesia using Optocain® (mepivacaine and adrenalin 1 : 100,000), fol…

Versos para Felipe V: teatro y propaganda borbónica en Peñíscola durante la Guerra de Sucesión Española
2019
El propòsit del present treball és analitzar el contingut propagandístic de l’obra de teatre amb el títol de Comedia famosa en que se representa el asedio o sitio de Peñíscola, que versa sobre el cerco a eixa fortalesa valenciana (desembre de 1705 a maig de 1707) durant la Guerra de Successió. Como esdevé en altres textos propis de la publicística borbònica, la finalitat adoctrinadora de l’obra es concentra en la legitimació de Felipe V mitjançant la identificació de la seua causa con la de la Providència, així com en la crítica a l’arxiduc Carles i els seus aliats, en un context de pugna por l’opinió entre los dos bàndols. Al mateix temps, la peça va servir de pretext per la construcció d’…
Plastic adjustments of biparental care behavior across embryonic development under elevated temperature in a marine ectotherm
2021
Abstract Phenotypic plasticity in parental care investment allows organisms to promptly respond to rapid environmental changes by potentially benefiting offspring survival and thus parental fitness. To date, a knowledge gap exists on whether plasticity in parental care behaviors can mediate responses to climate change in marine ectotherms. Here, we assessed the plasticity of parental care investment under elevated temperatures in a gonochoric marine annelid with biparental care, Ophryotrocha labronica, and investigated its role in maintaining the reproductive success of this species in a warming ocean. We measured the time individuals spent carrying out parental care activities across three…
