Predators and Tourism Increase Intolerance? A. Treves and J. Bruskotter Perspective in Ecology "Tolerance for Predatory Wildlife" (2 May, 344: 476) suggest that intolerance for predators do not fit into the conventional view of perceived threats for livelihoods but instead by complex social factors. Although the above perspective focuses in jaguars, wolves, lions and bears, the same reasoning is perfectly applied to other economical contexts and different human-wildlife interactions. Nature tourism is a growing industry attracting a significant number of people to exotic places to see wildlife and, of course, many predators are on the main "menu". [...].

Realization that hard coastal infrastructures support lower biodiversity than natural habitats has prompted a wealth of research seeking to identify design enhancements offering ecological benefits. Some studies showed that artificial structures could be modified to increase levels of diversity. Most studies, however, only considered the short-term ecological effects of such modifications, even though reliance on results from short-term studies may lead to serious misjudgements in conservation. In this study, a sevenyear experiment examined how the addition of small pits to otherwise featureless seawalls may enhance the stocks of a highly-exploited limpet. Modified areas of the seawall supported enhanced stocks of limpets seven years after the addition of pits. Modified areas of the seawall also supported a community that differed in the abundance of littorinids, barnacles andmacroalgae compared to the controls. Responses to different treatments (numbers and size of pits) were speciesspecific and, while some species responded directly to differences among treatments, others might have responded indirectly via changes in the distribution of competing species. This type of habitat enhancement can have positive long-lasting effects on the ecology of urban seascapes.Understanding of species interactions could be used to develop a rule-based approach to enhance biodiversity.
