Biochar is a carbon rich product which created under low Oxygen conditions. In this study the effect of Biochar in three levels 0, 0.5 and 1 weight percentage on morphological traits like height, SLA, aboveground and underground biomass, length and volume of root and physiological characteristics such as chlorophylls, gas exchange and electrolyte leakage for two Bromus tomentellus and Medicago ...

While invasive plant species primarily occur in disturbed, high-resource environments, many species have invaded ecosystems characterized by low nutrient, water, and light availability. Species adapted to low-resource systems often display traits associated with resource conservation, such as slow growth, high tissue longevity, and resource-use efficiency. This contrasts with our general unders...

In vertebrates, melanin-based coloration is often associated with variation in physiological and behavioural traits. We propose that this association stems from pleiotropic effects of the genes regulating the synthesis of brown to black eumelanin. The most important regulators are the melanocortin 1 receptor and its ligands, the melanocortin agonists and the agouti-signalling protein antagonist...

Drought-induced tree mortality has been observed globally and is expected to increase under climate change scenarios, with large potential consequences for the terrestrial carbon sink. Predicting mortality across species is crucial for assessing the effects of climate extremes on forest community biodiversity, composition, and carbon sequestration. However, the physiological traits associated w...

The process of plant speciation often involves the evolution of divergent ecotypes in response to differences in soil water availability between habitats. While the same set of traits is frequently associated with xeric/mesic ecotype divergence, it is unknown whether those traits evolve independently or if they evolve in tandem as a result of genetic colocalization either by pleiotropy or genet...

The genetic architecture of complex traits underlying physiology and disease in most organisms remains elusive. We still know little about the number of genes that underlie these traits, the magnitude of their effects, or the extent to which they interact. Chromosome substitution strains (CSSs) enable statistically powerful studies based on testing engineered inbred strains that have single, un...

Glossary Adaptation A genetically controlled trait that has evolved by natural selection. Analogous traits Similar traits that evolved independently in different species in response to similar environmental pressures. Comparative psychology The study of mind and behavior in nonhuman animals. Convergent evolution The process by which natural selection produces similar adaptations in different sp...
