Separating Leaves from Browse for Use in Nutritional Studies with Herbivores

Sifting through Nutritional Science: Separating Hype From Scientific Research

Your clients are besieged on a daily basis with health information from a variety of sources— the Internet, newsgroups, blogs, the media, as well as friends and family. Information is often piecemeal, taken out of context, or not based in sound science—and often contradicts other “authorities.” People are increasingly making decisions based on anecdotes and testimonials rather than credible sci...

Wild herbivores in forests: four case studies

A three population system with a top predator population, i.e. the herbivores, and two prey populations, grass and trees, is considered to model the interaction of herbivores with natural resources. We apply the model for four natural mountain parks in Northern Italy, three located in the Eastern Alps, two of which in the Dolomites and one in the Julian Alps, and one in the Maritime Alps, North...

Insect herbivores can choose microclimates to achieve nutritional homeostasis.

The interaction between temperature and diet quality can affect the life history of ectotherms. The rate and ratio at which protein and carbohydrate are obtained from food are important aspects of diet quality, and insects have a well-developed capacity to adjust their feeding behaviour and post-ingestive physiology to regulate intake and allocation of these nutrients. If the supply of protein ...

Coexisting generalist herbivores occupy unique nutritional feeding niches.

A mainstay of ecological theory and practice is that coexisting species use different resources, leading to the local development of biodiversity. However, a problem arises for understanding coexistence of multiple species if they share critical resources too generally. Here, we employ an experimental framework grounded in nutritional physiology to show that closely related, cooccurring and gen...
