These dispersers are crucial to the survival and fitness of plants \u2013 the pattern of dispersal can determine survivorship at the individual level, population dynamics at the community level and eventual evolution at the species level. From bats to mice to robins and monkeys, mammals and birds make up the majority of these seed dispersers by feeding on plant parts and then depositing them, out the other end, somewhere else.<\/span><\/p>\n<p><span style=\"color: #000000\">But a new study in the journal Oecologia reminds us that there are some unlikely seed dispersers that can be pretty important as well: namely, fish.<\/span><\/p>\n<p><span style=\"color: #000000\">Wait, you say.

Some 200 species of fish on this continent move into temporarily flooded habitats during the flood season, where they feed on fruits dropped into the water from trees and shrubs.\u00a0 The researchers studied two species in the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Pacu\" target=\"_blank\" rel=\"noopener noreferrer\">pacu<\/a> family, both of which can grow to a massive 25 kg and more than three meters in length. Their results show that the fishes are in fact important seed dispersers, redistributing seeds from about 35 percent of the species in the area. \u00a0The seeds deposited in the floodplain can germinate and grow after the floodwaters recede.<\/span><\/p>\n<p><span style=\"color: #000000\">The authors also note that larger fish are more effective seed dispersers, and that overfishing of the larger individuals could lead to reduced seed dispersal and changes in community dynamics.<\/span><\/p>\n<p><span style=\"color: #000000\">Read more in the <a href=\"http:\/\/www.springerlink.com\/content\/3508442928g18217\/\" target=\"_blank\" rel=\"noopener noreferrer\">Oecologia paper<\/a> (subscription only).<\/span><\/p>\n<p><span class=\"Z3988\" title=\"ctx_ver=Z39.88-2004&amp;rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&amp;rft.jtitle=Oecologia&amp;rft_id=info%3Adoi%2F10.1007%2Fs00442-009-1371-4&amp;rfr_id=info%3Asid%2Fresearchblogging.org&amp;rft.atitle=High-quality+seed+dispersal+by+fruit-eating+fishes+in+Amazonian+floodplain+habitats&amp;rft.issn=0029-8549&amp;rft.date=2009&amp;rft.volume=&amp;rft.issue=&amp;rft.spage=0&amp;rft.epage=0&amp;rft.artnum=http%3A%2F%2Fwww.springerlink.com%2Findex%2F10.1007%2Fs00442-009-1371-4&amp;rft.au=Anderson%2C+J.&amp;rft.au=Salda%C3%B1a+Rojas%2C+J.&amp;rft.au=Flecker%2C+A.&amp;rfe_dat=bpr3.included=1;bpr3.tags=Biology%2CEcology%2C+Botany%2C+Evolutionary+Biology\">Anderson, J., Salda\u00f1a Rojas, J., &amp; Flecker, A.
