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, …

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…

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’…

Late Pliocene and Pleistocene small mammal chronology in the Italian peninsula

2007

The abundant documentation of small mammals in the Italian peninsula, collected over recent years, furnishes a detailed biochronological sequence mainly from the Late Pliocene onwards. An updated stratigraphic framework is here presented, based on the European small mammal biozonation. The Early Villanyian is characterized by Mimomys hassiacus, M. stehlini, and, later, poorly documented M. polonicus. The Late Villanyian localities are well characterized with M. pliocaenicus, M. pitymyoides and M. tigliensis. The older part of the Early Biharian is documented by assemblages containing Microtus (Allophaiomys) ex gr. pliocaenicus, M. pusillus, M. cf. ostramosensis and M. tornensis, while the l…

Impact of secondary succession in abandoned fields on some properties of acidic sandy soils

2020

Abstract Abandonment of agricultural lands in recent decades is occurring mainly in Europe, North America and Oceania, and changing the fate of landscapes as the ecosystem recovers during fallow stage. The objective of this study was to find the impact of secondary succession in abandoned fields on some parameters of acidic sandy soils in the Borská nížina lowland (southwestern Slovakia). We investigated soil chemical (pH and soil organic carbon content), hydrophysical (water sorptivity, and hydraulic conductivity), and water repellency (water drop penetration time, water repellency cessation time, repellency index, and modified repellency index) parameters, as well as the ethanol sorptivit…
