The stimulatory effect of testosterone on male sexual activity is one of the clearest examples linking hormones and behaviors. However, this relationship is complex in Chelonians. We experimentally studied the influence of testosterone levels on the activity budget and space use in male Greek tortoises (Testudo graeca graeca) during the spring mating season. We first described the annual patter...
One of the most extensive species radiations in tardigrade evolution took place Echiniscus phylogenetic line, which contains genus with over 120 described to date. The internal classification is historically based on two major sources variability: chaetotaxy, that arrangement and shape trunk appendages, sculpturing dorsal plates. These criteria allowed for delineation complexes, such as blumi-c...
A major difference between reptile and mammalian herbivores is that the former do not masticate their food. Actually, food particle size reduction by chewing is usually considered one of the adaptations facilitating the higher metabolic rates of mammals. However, quantitative comparisons of ingesta particle size between the clades have, to our knowledge, not been performed so far. We measured m...
