Species inventories provide the basic information for biodiversity studies. Designing cost-effective species inventories is important in estimating the species richness or the number of additional species expected in a study area. Complete species inventories are difficult to achieve and a variety of estimation methods are available to counter the underestimation of species richness associated with incomplete sampling. A main criterion of selecting

During the past century, habitat fragmentation and increased human impacts have reduced populations of large carnivores throughout the world. Although bears have been extirpated from human-dominated landscape in most parts of Europe, they still occur in multi-use cultural landscapes in Southern Transylvania, Romania. Wood-pastures—grazed permanent grasslands with scattered or clumped trees and shrubs—are important elements of these cultural landscapes

The nonheme peroxidase, rubrerythrin, shows the ability to reduce hydrogen peroxide to water without involving strongly oxidizing and free-radical creating powerful oxidants such as compounds I and II [formally Fe(IV)] formed in peroxidases and catalases. Rubrerythrin could, therefore, be a useful ingredient in protein-based artificial oxygen carriers. Here, we report that the oxygen-carrying proteins, hemoglobin (Hb) and hemerythrin (Hr), can each
