As Sea Temperatures Rise, the Nutritional Value of Giant Kelp Decreases

As Sea Temperatures Rise, the Nutritional Value of Giant Kelp Decreases

The ecology of the temperate, shallow, nearshore seas where giant kelp (Macrocystis pyrifera) thrives is dependent on it as a basic species. When the fast-growing species thrives, so do the populations that rely on it for food and shelter. The world’s seas are warming, with average temperat.....

Insect Digestive Enzymes can Degrade Plant Defense Chemicals, Influencing the Insects’ Selection for Specific Food Sources

Insect Digestive Enzymes can Degrade Plant Defense Chemicals, Influencing the Insects’ Selection for Specific Food Sources

Plants aren’t completely helpless against their herbivore foes. Chemical defenses frequently render plants inedible, if not poisonous, and as a result, insects and other hungry animals avoid them. Insects meet their nutritional needs by consuming food from the environment and digesting it p.....

Tobacco Hawkmoths Benefit from Learning to Select a Nectar Source and Oviposition Site More Efficiently

Tobacco Hawkmoths Benefit from Learning to Select a Nectar Source and Oviposition Site More Efficiently

Scientists from the Department of Evolutionary Neuroethology, directed by Bill Hansson and Markus Knaden, had previously demonstrated that tobacco hawkmoths can learn scents as signals to a nectar source that they first found disagreeable. Insects have been discovered to be extremely adaptable to.....
