Aquatic organisms respond to flooding, drought disturbance in different wa
Updated : 3 years, 1 month ago IST
Populations of various species of aquatic insects and other invertebrates respond to flooding and waterway drying due to drought in different ways that can be anticipated, according to a new Penn State-led study that employed a novel method to assess the stability of stream ecosystems.

How species adapt: Ancestral variation guides future environmental adaptat
Updated : 3 years, 1 month ago IST
The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to -- this is known as phenotypic plasticity.

Research shows that exercise promotes a molecular profile in muscle
Updated : 3 years, 1 month ago IST
A recent paper published in the Journal of Physiology deepened the case for the youthfulness-promoting effects of exercise on ageing organisms, building on previous work done with lab mice nearing the end of their natural lifespan that had access to a weighted exercise wheel.

Study finds how specific nutrients affect neuronal development
Updated : 3 years, 1 month ago IST
It appears that nutrition affects an organism's physiological status at every stage of life. Although it is well recognised that neuronal development, particularly the growth of dendrites and axons, is metabolically demanding, little is known about the effects of different foods on neuronal

Study reveals reduction in impact of prairie dog plague on other organisms
Updated : 3 years, 2 months ago IST
According to a study published in the journal Ecological Applications,' when a sylvatic plague outbreak decimated black-tailed prairie dog populations in the Thunder Basin National Grassland in 2017, researchers saw an opportunity for a "natural experiment" to investigate the impact of the r

'Jumping genes' help fungus kill salamanders: Research
Updated : 3 years, 2 months ago IST
A fungus that infects salamanders contains multiple copies of the same "jumping genes", scientists have discovered. Jumping genes, called transposons, can "copy and paste" themselves and impact the organism.

Ethereal colour variant of mysterious plant is actually a new species: Stu
Updated : 3 years, 2 months ago IST
Green leaves and photosynthesis were once considered essential characteristics of plants. However, some plants have stopped performing photosynthesis and take the nutrients they need from other organisms instead.

New study explores circadian clock of fruit fly
Updated : 3 years, 2 months ago IST
The higher the temperatures, the faster physiological processes are. However, there is an exception: the so-called circadian clock, which regulates the sleep-wake cycle in organisms.

Study finds how virovory is enough to fuel physiological growth
Updated : 3 years, 2 months ago IST
Researchers discovered that a type of Halteria, which are tiny ciliates that live in freshwater habitats all over the world, may consume large quantities of infectious chloroviruses. For the first time, the team's laboratory tests have also demonstrated that a virus-only diet, or "virovory,"
