Chronic morpholine exposure of rats

open access: yesFundamental and Applied Toxicology, 1989
The chronic toxicity and carcinogenic potential of morpholine were evaluated in 60 Sprague-Dawley rats/sex/group receiving morpholine at mean inhalation exposure concentrations of 0, 10, 50 and 150 ppm for 6 hr/day, 5 days/week, for 104 weeks. Survival, body weight gains, organ weights, hematology, and clinical chemistries were normal in exposed groups

Biogeographical analysis within the family Phytoseiidae Berlese (Acari: Mesostigmata): an example from the large sub-genus Typhlodromus (Anthoseius) De Leon [PDF]

open access: yes, 2011
Despite their great interest for pest management, the biogeography of the Phytoseiidae is still poorly known. This study focuses on the spatial distribution of one of the largest taxa within the family: the sub-genus Typhlodromus (Anthoseius) currently ...
