Short-term rate maximization when rewards and delays covary
Article Abstract:
A model was developed to analyze the relationship between the choice of resources of a forager constrained to evaluate options in maximizing short-term rate energy gain and variance-covariance levels for rewards and delays. The model predicts that a forager would prefer resources with larger rewards and short delays. The model also predicts that increased delay variance and decreased reward-delay covariance increases preference for a resource. However, a positive reward-delay covariance makes the forager risk-aversive towards reward variance. A negative reward-delay covariance makes the consumer risk-prone towards rewards.

Striped rabbits in Southeast Asia
Article Abstract:
A striped rabbit of the Nesolagus genus was found in the Annamite mountains of Laos and Vietnam. The only previously known striped lagomorph was the endangered Nesolagus netscheri, a monotypic rabbit genus. There is a high degree of conserved morphology, and the large genetic divergence between the two taxa of striped rabbit, suggests that they separated in the Pliocene epoch.
