Risk assessment of nitrate and nitrite in feed

EFSA Journal, Volume 18, Issue 11, November 2020., 2020
Abstract The European Commission asked EFSA for a scientific opinion on the risks to animal health related to nitrite and nitrate in feed. For nitrate ion, the EFSA Panel on Contaminants in the Food Chain (CONTAM Panel) identified a BMDL10 of 64 mg nitrate/kg body weight (bw) per day for adult cattle, based on methaemoglobin (MetHb) levels in animal's ...

Evolution of protamine genes and changes in sperm head phenotype in rodents [PDF]

, 2016
Little is known about the genetic basis of evolutionary changes in sperm phenotype. Postcopulatory sexual selection is associated with differences in protamine gene sequences and promoters and is a powerful force acting on sperm form and function ...

Filogenia molecular, cromossomos e dispersão em akodontinos do Brasil (Rodentia, Sigmodontinae) [PDF]

, 2009
A new molecular phylogeny for akodontine rodents from Brazil was proposed. The phylogenetic tree was enriched with the area of occurrence and with information on the karyotype of the samples. Based on this enriched tree, and with a described methodology,

Phylogeography of the Tibetan hamster Cricetulus kamensis in response to uplift and environmental change in the Qinghai–Tibet Plateau

Ecology and Evolution, Volume 9, Issue 12, Page 7291-7306, June 2019., 2019
Major genetic differentiations of Cricetulus kamensis occurred in the late Pliocene. Cricetulus kamensis populations were restricted into two major clades due to tectonic movement of QTP and the Last Glacial Maximum. Abstract Aim The evolutionary process of an organism provides valuable data toward an understanding of the Earth evolution history.

Ecology and diversity of Cricetidae familiy (Mammalia) in Croatia [PDF]

, 2018
Porodica Cricetidae vrlo je raznolika i brojna, te je raširena po gotovo čitavoj Zemlji. Postoji 6 potporodica, a u Hrvatskoj nalazimo predstavnike dviju od njih: Arvicolinae (voluharice) i Cricetinae (hrčci).
