We used growth rates (estimated from otolith microstructure), morphometric (Fulton’s K condition index) and lipid (triacylglycerols:sterols ratio, TAG:ST) condition indices measured on 0-group juveniles of common sole, to compare the habitat quality of 7 nursery grounds with differing levels of anthropogenic pressure. Along the French coast of the Southern Bight of the North Sea and the Eastern...

Despite considerable speculation virtually nothing is known about the empirical relationship between traditional Tibetan administrative systems, household processes, and demographic trends in historical Tibetan populations because indigenous data sources have never been systematically analyzed. This article examines a 1958 tax register from Kyirong, formerly a district-level political division ...

We study connections between the Boyd indices in Orlicz spaces and the growth conditions frequently met in various applications, for instance, in the regularity theory of variational integrals with non-standard growth. We develop a truncation method for computation of the indices and we also give characterizations of them in terms of the growth exponents and of the Jensen means. Applications co...

Studies of multiple taxa across broad-scales suggest that species distributions are shifting poleward in response to global climate change. Understanding the influence of distribution shifts on regional population indices will be an important part of interpreting population trends within local management units because, compared to a time when distribution were less dynamic, changes in populatio...

The 20th century has seen unprecedented growth of the human population on this planet. While at the beginning of the century the Earth had an estimated 1.6 billion inhabitants, this number grew to 6.1 billion by the end of the century, and further significant growth is a near certainty. This paper tries to summarize what factors lie behind this extraordinary expansion of the human population an...

natural climatic conditions in urban areas can be changed by human physical environment. climate as a natural system and city as a human system have close mutual connections. urban population growth and consequent increase in urban physical expansion may lead to intensification in human activities and disturbances in the environment. this contributes to alterations in solar radiation, balance o...

Introduction: Head circumference (HC) measurement is one of the important parameter for diagnosis of neurological, developmental disorders and dysmorphic syndromes. Recognition of different disorders requires an understanding of normal variation for HC size, in particular, in infancy period with most rapid growth of the brain. Because of international and interracial standard chart differences ...

This paper seeks to relate proxy indices of economic performance to competing hypotheses of sustainable and unsustainable intensive economic growth in the Roman world. It considers the economic relevance of certain types of archaeological data, the potential of income-centered indices of economic performance, and the complex relationship between economic growth and incomes documented in the mor...
