Cellular aspect ratio and cell division mechanics underlie the patterning of cell progeny in diverse mammalian epithelia. [PDF]

open access: yes, 2018
Cell division is essential to expand, shape, and replenish epithelia. In the adult small intestine, cells from a common progenitor intermix with other lineages, whereas cell progeny in many other epithelia form contiguous patches.

Habitat fragmentation reduces plant progeny quality: a global synthesis.

open access: yesEcology Letters, 2019
Most of the world's land surface is currently under human use and natural habitats remain as fragmented samples of the original landscapes. Measuring the quality of plant progeny sired in these pervasive environments represents a fundamental endeavour ...

Effects of Maternal and Progeny Dietary Vitamin Regimens on the Performance of Ducklings

open access: yesThe Journal of Poultry Science, 2018
This study evaluated the interaction effect of maternal and progeny vitamin regimens on the performance of ducklings. At 38 weeks of age, 780 female and 156 male duck breeders were fed either regular or high vitamin premix diet (maternal high premix had ...

Development of a suitable rearing media for Tribolium castaneum

open access: yesJulius-Kühn-Archiv, 2018
Tribolium castaneum is a serious pest of cereal flour and flour-based products, and thus a test insect in storedproduct research. The composition of the rearing medium affects the progeny production, their performance and handling efficacy. The objective

Transgenerational effects of parental light environment on progeny competitive performance and lifetime fitness

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2019
Plant and animal parents may respond to environmental conditions such as resource stress by altering traits of their offspring via heritable non-genetic effects.

Does paternal sterility impact on progeny germination and survivorship, case study in strawberries

open access: yesActa Agriculturae Slovenica, 2014
Studies on the parental role on progeny performance have mostly focused on the maternal parent, while less attention was given to the paternal parent.

Genetic exchange in Trypanosoma brucei: evidence for mating prior to metacyclic stage development [PDF]

open access: yes, 2005
It is well established that genetic exchange occurs between Trypanosoma brucei parasites when two stocks are used to infect tsetse flies under laboratory conditions and a number of such crosses have been undertaken.

Multi-trait multi-environment models in the genetic selection of segregating soybean progeny

open access: yesPLoS ONE, 2019
At present, single-trait best linear unbiased prediction (BLUP) is the standard method for genetic selection in soybean. However, when genetic selection is performed based on two or more genetically correlated traits and these are analyzed individually ...
