Numerous interactions between plants and animals vary in their outcome predation mutualism. Depending on the costs benefits, relationship is placed at one end of scale or other. A thin line separates both interactions. Acorn consumption by rodent species has been considered a relationship. Rodents consume acorns, which cost to oaks as they are prevented from colonizing new places. The aim this ...

Abstract Hardwoods resprouting after wildfire or cutting develop as multistemmed clumps that gradually self-thin over time. There is increasing interest in thinning of sprouting species to accelerate the formation tree characteristics important indigenous cultural practices and wildlife such large-diameter stems, large branches, broad crowns, acorn production. We compared responses three treatm...

Archimedes was the first to systematically find the centers of gravity of various solid bodies and to apply this concept in determining stable configurations of floating bodies. In this paper, we discuss an error in a proof developed by Archimedes that involves determining whether a uniform, spherical cap will float stably with its base horizontal in a liquid on a spherical Earth. We present a ...

The study of Russian dialectal vocabulary remains one the most pressing problems etymology. This article is devoted to origin and history a number dialect words. Namely, author provides revised explanations for some dialecticisms from already published issues Etymological Dictionary (говéд(т)ник, дохóрь, дóхта, сбрéндить), as well its unpublished (есáк, жёл, жерсть, жúмы). Most this material mi...

Barnacle adhesion underwater is an important phenomenon to understand for the prevention of biofouling and potential biotechnological innovations, yet so far, identifying what makes barnacle glue proteins 'sticky' has proved elusive. Examination of a broad range of species within the barnacles may be instructive to identify conserved adhesive domains. We add to extensive information from the ac...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(2): 579–585. In this study, the impact of wild boar on the natural regeneration of oak and importance of acorns in the wild boar di...

Some length-preserving operations on strings only permute the symbol positions in strings; such an operation X gives rise to a family {Xn}n≥2 of similar permutations. We investigate the structure and the order of the cyclic group generated by Xn. We call an integer n X-prime if Xn consists of a single cycle of length n (n ≥ 2). Then we show some properties of these X-primes, particularly, how X...
