They make benthic primary production available to invertebrate and vertebrate predators. However, their community biomass is strongly influenced by the nutritional quality of periphytic algae. In this study, several factors that potentially determine the nutritional quality of periphyton for gastropod grazers (and strategies of the snails to cope with food quality constraints) were investigated both in the field and under standardised conditions in laboratory growth experiments. As food quality is patchily distributed, it should be highly adaptive for gastropod herbivores to utilise chemical cues in order to detect patches of (high quality) food. In particular, volatile organic compounds released from benthic algae can be used by the snails as foraging kairomones that indicate the presence of a food patch. These adaptations probably contribute to the extreme success of freshwater gastropods in many lake and river littoral zones.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Patrick Fink\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3832512039\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783832512033\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Logos Verlag Berlin\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/15\/2006\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 133\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback","brand":"Patrick Fink","offers":[{"title":"Paperback","offer_id":48450114912511,"sku":"9783832512033","price":61.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_2366238f-383b-4519-ada6-3b83ce6a1286.jpg?v=1777266279","url":"https:\/\/www.whiterainbookhouse.com\/products\/food-quality-and-food-choice-patrick-fink-9783832512033","provider":"WR Book House","version":"1.0","type":"link"}
