A new study has developed advanced, non-destructive models to measure the aboveground biomass and volume of Populus euphratica, a keystone tree in desert riparian forests. These models reduce errors by nearly half compared to traditional equations, providing new tools for forest conservation and carbon storage assessment.
Feralisation in rabbits leads to variable body sizes and skull shapes that don't simply revert to wild or domestic forms. The study suggests environmental factors drive these changes, potentially influenced by evolutionary pressures and habitat conditions.
Research published in the European Heart Journal found that people with high amounts of intermuscular fat are more likely to develop coronary microvascular dysfunction and future serious heart disease. The study's lead author suggests that existing measures of obesity may not be accurate for all individuals, particularly women.
New research by University College Cork scientists finds that pterosaurs had nurturing parental style but only in larger species. The study suggests that smaller pterosaurs did not practice parental care due to the limitations of egg size.
Researchers found that large hagfishes grow extremely large cells to produce stronger slime threads used in defensive attacks. The thread cells are highly dependent on body size and show a scaling factor of 0.55, much larger than other vertebrates.
A study of over 7,500 participants refutes the idea that the 2D:4D ratio is influenced by sex hormones, instead suggesting that finger size differences are related to overall growth patterns. The research found no correlation between total finger length and 2D:4D ratio in men and women across different ages and nationalities.
New Army research applies trends from historical weapon systems, including crossbows and tanks, to explore potential future systems. A single regularity describes the growth of diverse families of technology over multiple centuries.
Reproductive rates in humans are linked to metabolic energy expenditure and body mass, with women in wealthy nations experiencing low birth rates due to high caloric intake. This relationship highlights the importance of considering biological scaling laws when understanding human reproductive patterns.
