The Flora of Mosses on the Załęcze Nature Park Area (Wieluń Upland)

The paper contains a list of species and floristic analysis of mosses in the Załęcze Nature Park. There were collected and determinated 99 species of mosses (for summary see page 363).Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej naukę

Nutritional dynamics during the development of xylophagous beetles related to changes in the stoichiometry of 11 elements

The present study examines the adaptive strategy used by wood-boring beetles to compensate for the lack of nutrients in dead wood. The contents of nutritional elements in growing wood-boring beetles (Stictoleptura rubra L. and Chalcophora mariana Dejean) are compared with the elemental composition of decaying dead wood (pine stumps), showing changes during the beetles' ontogenetic (i.e. larval) development. The stoichiometric ratios of C and other nutritional elements (N, P, K, Na, Ca, Mg, Fe, Zn, Mn and Cu) are investigated to identify the most important nutrients for larval development. The degree of nutritional mismatch that is encountered by the beetle larvae changes dramatically over 3-4 years of simultaneous larval growth and wood decay. Excluding C, the relative contents of nutritional elements increase substantially in decaying wood, whereas the opposite tendency is found in larvae, most likely because of carbon deposition in fat. The elements limiting larval development because of their scarcity in dead wood are N, P, K, Na, Mg, Zn and Cu. Fungal activity (i.e. the transport of nutrients from the surrounding environment to decaying stumps) can explain the observed mitigation of the original mismatch, although prolongation of the larval development time is still necessary to compensate for the scarcity of some of the required elements in food

Fungal transformation of tree stumps into a suitable resource for Xylophagous Beetles via changes in elemental ratios

The elements present in dead pine stumps inhabited by larvae of wood-boring beetles (Stictoleptura rubra, Arhopalus rusticus and Chalcophora mariana) were analyzed over the initial (first 5 years; a chronosequence) stages of wood decay. The quantities of N, P, K, Ca, Mg, Fe, Zn, Mn, Cu and Na (but not S) increased with increases in the content of ergosterol (used as a proxy for the amount of fungal tissue). In fact, the amounts of P, N, K, Fe and Cu presented marked increases. These findings show that fungi stoichiometrically rearrange dead wood by importing externally occurring nutrients to decaying stumps. During the first years of wood decay, the ratios of C to other elements decrease substantially, but differently, for various elements, whereas the N:Fe, N:Cu, N:P and N:K ratios remain relatively stable. Therefore, the stoichiometric mismatch between xylophages and their food is greatly reduced. By changing the nutritional stoichiometry of dead wood, fungi create a nutritional niche for wood-eaters, and these changes enable the development of xylophages

Female empowerment, cultural effects and savings: Empirical evidence from India

This paper looks at household consumption and financial decisions made in a matrilineal society where women are by culture the financial household managers. This culture was strongly altered by the British in the mid-19th century in particular through christian missionaries who proclaimed that the role of the household manager is ascribed to men and not to women. Using two different datasets, our results show that female empowerment is stronger and individuals keep following the traditional matrilineal Khasi rules the further they live away from the former British base. Instrumental variable estimates exploiting differences in distance to the former British base in Cherrapunji, suggest that households where women are empowered, spend more on welfare enhancing goods such as education and nutrition, but are less likely to have savings left at the end of the month, and that these effects are causal

Intra-household decision making and long-term welfare effects: New empirical evidence.

This paper looks at household consumption and financial decisions made in a matrilineal society where women are by culture the financial household managers. This culture was strongly altered by the British in the mid-19th century. We use the distance to the former base as an instrument for women empowerment. Results show that households that follow the matrilineal Khasi tradition, spend more on education and nutrition, but are less likely to have savings left at the end of the month

Geobotanical Characteristics of the "Lasek Kurowski" Reserve near Wieluń

The article presents results of the geobotanical studies on the partial forest reserve of "Lasek Kurowski" situated near Wieluń in the Sieradz Administrative Province. An object of protection are the Tilio-Carpinetum with participation of the Abies alba and fragments of the Ribo nigri-Alnetum.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej naukę

Fir-Oak-Hombeam Forest Regeneration in the „Jamno” Reserve

The present study describes changes that have occured in the phytocoenosis of Pino-Quercetum abieieiosuni in the „Jamno” reserve. It was determined that the vegetation of this reserve, due to its high dynamics, recovers to its natural form of Tilio-Carpinetum lypicum with Abies alba. The disapperance of Pinus silvestris from all layers of the phytocoenosis and an essential increase in Carpinus betulus and Quereus rohur in the tree-stand was observed. A slight quantitative increase in Abies alba in the tree-stand was also noticed. Changes in the field layer consist mainly in the extinction of species typical of coniferous and increase in species typical of deciduous forests.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej naukę
