The genus Anthoxanthum s.l. (including Hierochloë) (Poaceae, Pooideae, Aveneae) comprises 35– 50 species and has a cosmopolitan distribution. Anthoxanthum alpinum was described as a diploid perennial that is distributed in northern Eurasia and in the high mountains of central and eastern Europe. Difficulties in finding reliable morphological differences between this taxon and the widespread tet...

“ Octopus ” rubescens Berry, 1953 is an octopus of temperate waters the western coast North America. This paper presents first record O. from tropical Mexican Pacific. Twelve octopuses were studied; 10 collected in tide pools five localities and two mature males caught by fishermen Oaxaca. We used morphometric characters anatomical features digestive tract to identify specie...

A number of anatomical characters of crocodilians appear to be inconsistent with their lifestyle as sit-and-wait predators. To address this paradoxical association of characters further, we measured lung ventilation and respiratory gas exchange during walking in American alligators (Alligator mississippiensis). During exercise, ventilation consisted of low-frequency, large-volume breaths. The a...

This work investigates the phylogenetic relationships within Grimmia Hedw. using 33 species of Grimmia and ten outgroup species from the Funariidae and the Dicranidae using a combination of two molecular markers and 52 morphological and anatomical characters. Plastid (trnL-trnF and rps4) DNA sequences were used to reconstruct the molecular phylogeny of Grimmia. The 33 chosen Grimmia species rep...
