The evolution of sperm morphometry in pheasants [PDF]

open access: yes, 2007
Postcopulatory sexual selection is thought to be a potent evolutionary force driving the diversification of sperm shape and function across species. In birds, insemination and fertilisation are separated in time and sperm storage increases the duration

Assessing Reef Island Sensitivity Based on LiDAR-Derived Morphometric Indicators [PDF]

open access: yesRemote Sensing, 2020
Reef islands are some of the most highly sensitive landforms to the impacts of future environmental change. Previous assessments of island morphodynamics primarily relied on historical aerial and satellite imagery. These approaches limit analysis to two-dimensional parameters, with no ability to assess long-term changes to island volume or elevation ...

Morphometric characterization and body development indices of krivovir pramenka [PDF]

open access: yes, 2023
The Krivovir pramenka was created by crossing silk-fleece rams from Asia with local sheep. During World War II, it was crossed with Merino rams used for meat production, while pure breed breeding for the purpose of preservation of this indigenous population, started at the end of the 20th century.
