Unimodal response of tree species richness to increases in aboveground productivity is evident grasslands but a lesser extent forests, where confounding factors (e.g., abiotic and management regimes) may alter the compromise delivery ecosystem services. We hypothesize that unimodal biomass accumulation through increased leads greater above ground carbon (AGC) stocks thus climate regulation not ...

Two 60 day experiments on predation behavior of leeches were conducted concurrently. In the first, medicinal leeches, Hirudo orientalis (Utevsky and Trontelj, 2005) were fed to satiation on bovine blood and subsequently transferred into two large opaque plastic containers of equal size but with differing temperatures, 6-7?C and 23-24?C, containing starved Erpobdella octoculata (L.). At the high...

Do listeners use lexical stress at an early stage in word learning? Artificial-lexicon studies have shown that listeners can learn new spoken words easily. These studies used nonwords differing in consonants and/or vowels, but not differing only in stress. If listeners use stress information in word learning, they should be able to learn new words that differ only in stress (e.g., BInulo-biNUlo...
