The Importance of Functional Morphology for Fishery Conservation and Management: Applications to Hawaiian Amphidromous Fishes
The functional capabilities of species can have a strong effect on their ability to maintain sustainable populations in anthropogenically altered environments. This is especially true among species comprising freshwater ichthyofaunas on small oceanic islands, where fishes frequently traverse boundaries between different ecosystems. Many aspects of functional performance in fishes relate directl...
متن کاملInsect Introductions and Diet Changes in an Endemic Hawaiian Amphidromous Goby, Awaous stamineus (Pisces: Gobiidae)l
Data are presented from gut content analysis of 94 Awaous stamineus (Edouyx & Souleyet) ('o'opu niikea) collected from the Wainiha River on the north shore of the Hawaiian island of Kaua'i during the period from June 1990 to May 1991. Also presented are results from gut analysis of 11 preserved museum specimens captured in Lii'iemalo'o stream, O'ahu, in February 1938 and June 1939. The results ...
متن کاملPerformance across extreme environments: comparing waterfall climbing among amphidromous gobioid fishes from Caribbean and Pacific Islands
Amphidromous gobioid fishes have colonized streams on tropical and subtropical volcanic islands across the globe. Such streams are often characterized by steep gradients, high velocity currents, and even waterfalls as in-stream obstacles; however, the ability to climb waterfalls has evolved in many goby species, allowing juveniles returning from the ocean to penetrate upstream reaches. Past stu...
متن کاملThe evolutionary ecology of alternative migratory tactics in salmonid fishes.
Extensive individual variation in spatial behaviour is a common feature among species that exhibit migratory life cycles. Nowhere is this more evident than in salmonid fishes; individual fish may complete their entire life cycle in freshwater streams, others may migrate variable distances at sea and yet others limit their migrations to larger rivers or lakes before returning to freshwater strea...
متن کاملParasites of Hawaiian Stream Fishes: Sources and Impacts
Introduced freshwater fishes impact native Hawaiian stream fishes in two important ways. In addition to direct negative effects associated factors such as predation, competition, and interference, indirect effects may occur when exotic fishes transfer their parasites to native hosts. Six species of helminths that have been introduced with alien live-bearing fishes, including guppies, green swor...
