Mastitis is the most common reason for antimicrobial treatment of dairy cows (Grave et al. 1999; Mitchell et al. 1998). Antimicrobials have been used to treat mastitis for more than fifty years, but consensus about the most efficient, safe, and economical treatment is still lacking. The concept of evidence based medicine has recently been introduced to veterinary medicine (Cockcroft & Holmes, 2...

plexity. This conclusion is conceptually similar to our own, and it little alters the broader impacts of our published findings; still, the general relevance of the issues warrants a response. In their reanalysis, Gutierrez-Ibanez et al. [2016] perform a ‘residual analysis’, which regresses body weight on brain weight with phylogenetic generalized least squares (PGLS) to obtain size-corrected r...

Comments on the phylogenetic relationships and taxonomy of American leafcutter bees of the genus Megachile Latreille subgenus Chrysosarus Mitchell are provided. The South American subgenera Austrosarus Raw, Stelodides Moure, and Zonomegachile Mitchell are newly synonymized under Chrysosarus (new synonymies). 1 Department of Biological Sciences, 100 Campus Drive, Southwestern Oklahoma State Univ...

TO THE EDITOR: We write you regarding an article named " Isolation and characterization of cholangiocyte primary cilia, " published by Huang et al. in September of 2006 (1). The Introduction of this article ends with the following sentences: " Despite these findings, our understanding of the functions of the primary cilium and its role in responding to environmental stimuli are still poorly und...

BACKGROUND AND AIMS In the last decade, genomic studies using DNA markers have strongly influenced the current phylogeny of angiosperms. Genome size and ploidy level have contributed to this discussion, being considered important characters in biosystematics, ecology and population biology. Despite the recent increase in studies related to genome size evolution and polyploidy incidence, only a ...

Drought-induced forest mortality is emerging as a widespread phenomenon with potentially large 12 implications for forest function and dynamics (Allen et al., 2010; Anderegg et al., 2012; Martínez13 Vilalta et al., 2012). Although the physiological mechanisms underlying tree mortality are still not 14 completely understood, there is agreement that they involve the storage and transport systems ...

Mitchell et al. argue that conditioning phenomena may be better explained by high-level, rational processes, rather than by noncognitive associative mechanisms. This commentary argues that this viewpoint is compatible with neuroscientific data, may extend to nonhuman animals, and casts computational models of reinforcement learning in a new light. Mitchell et al. provide an important critical c...
