Nekton Communities in Hawaiian Coastal Wetlands: The Distribution and Abundance of Introduced Fish Species

  title={Nekton Communities in Hawaiian Coastal Wetlands: The Distribution and Abundance of Introduced Fish Species},
  author={Richard A. Mackenzie and G. L. Bruland},
  journal={Estuaries and Coasts},
Nekton communities were sampled from 38 Hawaiian coastal wetlands from 2007 to 2009 using lift nets, seines, and throw nets in an attempt to increase our understanding of the nekton assemblages that utilize these poorly studied ecosystems. Nekton were dominated by exotic species, primarily poeciliids (Gambusia affinis, Poecilia spp.) and tilapia. These fish were present in 50–85% of wetlands sampled; densities were up to 15 times greater than native species. High densities of exotic fish were… 
The relative importance of introduced fishes, habitat characteristics, and land use for endemic shrimp occurrence in brackish anchialine pool ecosystems
Abstract Anchialine ecosystems are groundwater-fed brackish coastal habitats that contain high percentages of endemic fauna and are at risk from anthropogenic stressors, introduced species, and sea
Opening the floodgates to the recovery of nektonic assemblages in a temperate coastal wetland
The study illustrated that reinstating tidal flushing can recover nursery habitats and enhance populations of economically valuable species.
Modeling Potential Shifts in Hawaiian Anchialine Pool Habitat and Introduced Fish Distribution due to Sea Level Rise
Global mean sea levels may rise between 0.75 and 1.9 m by 2100 changing the distribution and community structure of coastal ecosystems due to flooding, erosion, and saltwater intrusion. Although
Differences in ecological structure, function, and native species abundance between native and invaded Hawaiian streams.
It is suggested that poeciliids may negatively impact the ecosystem structure, function, and native species abundance of tropical streams they invade, and underscores the need for increased public awareness to prevent future introductions and for developing and implementing effective eradication and restoration strategies.
Invasive fishes in the Hawaiian anchialine ecosystem: investigating potential predator avoidance by endemic organisms
Adopted behavioral responses to invasive fishes generally, though not universally, prevent predation on endemic Hawaiian anchialine shrimps, however, non-consumptive effects resulting from behavioral modification ofShrimps may have appreciable impacts on the Hawaiian anchIALine ecosystem and warrant further study.
Evaluating establishment success of non-native fishes introduced to inland aquatic habitats of tropical Pacific islands
Abstract. An information-theoretic approach was used to evaluate non-native freshwater fish species introduced to insular habitats of Hawaii and Guam comparing successful establishments vs. failures.
Impacts of exotic mangroves and chemical eradication of mangroves on tide pool fish assemblages
The data suggests that exotic mangroves in Hawaii are not having an adverse effect on native fish assemblages in tide pools, and may actually provide nursery habitat for native and exotic fish.
Introduced Mangroves along the Coast of Moloka‘i, Hawai‘i may Represent Novel Habitats for Megafaunal Communities
Abstract: Mangrove forests are prevalent along tropical/subtropical coastlines and provide valuable ecosystem services including coastline stabilization, storm impact reduction, and enhanced coastal
Interactions of water levels with water quality, endemic waterbirds, and invasive species in a shallow, tropical pond
This study responds to a need for baseline physical and chemical data in shallow tropical water bodies. We investigated the degree to which water level fluctuations affected water quality and biota
Effects of invasion at two trophic levels on diet, body condition, and population size structure of Hawaiian red shrimp
Primary succession by invasive trees may shift food web linkages in these ponds from autotrophic to heterotrophic support, without negative impacts on native grazer/detritivore communities.


Fish Assemblage of a Cypress Wetland within an Urban Landscape
Abstract Fishes were sampled from Gillam Park Wetland, a small cypress swamp located within the city limits of Little Rock, AR during Fall 2005. The objectives of this research were to contribute
Effects of introduced fish on aquatic insect abundance : a case study of Hamakua Marsh, Oahu Hawaiʻi
The African blackchin tilapia (Sarotherodon melanotheron) was introduced to Hawaii in 1951 for use as a baitflsh and to control aquatic weeds; poeciliid mosquitoflsh (Gambusia affinis, Poecilia
The loss of native biodiversity and continuing nonindigenous species introductions in freshwater, estuarine, and wetland communities of Pearl Harbor, Oahu, Hawaiian Islands
The first comprehensive assessment of the area found that nonindigenous species comprise the dominant portion of the biota and will likely continue to increase in the freshwater and estuarine portions Pearl Harbor because of the wide variety of sources from which introductions take place.
Invasion Patterns along Elevation and Urbanization Gradients in Hawaiian Streams
Hawaii's extreme isolation has resulted in a native stream fauna characterized by high endemism and unusual life history characteristics, but the viability of Hawaiian stream ecosystems is threatened by development and the associated habitat alteration.
Fish assemblage composition in constructed and natural tidal marshes of San Diego Bay: Relative influence of channel morphology and restoration history
This study evaluated the use by fish of restored tidal wetlands and identified links between fish species composition and habitat characteristics. We compared the attributes of natural and
Non-native fishes and native species diversity in freshwater fish assemblages across the United States
Examining the influence of non-native fish species on native freshwater fish assemblages across the United States suggests that from a superficial perspective, native species richness and diversity are not different among sites with and without non- native species.
Parasites of Hawaiian Stream Fishes : Sources and Impacts
Sources, host specificity, distribution, and life cycles of these parasites were studied to assess their potential for pathogenicity and to aid in the formulation of comprehensive conservation and management plans for native stream species in Hawai‘i.
Exotic Fish Biodiversity in Churni River of West Bengal, India
It may be concluded that the reverine ecosystem consisting various natural foods in different niches of the river is an important exotic fish diversified zone and the exotic fishes, as an efficient consumer of these foods, reduce the river pollution and stabilize the riverine ecosystem and acts as an instrument for yield optimization in the river.
Multi-trophic invasion resistance in Hawaii: bioacoustics, field surveys, and airborne remote sensing.
A multi-trophic analysis strongly suggests that native avifauna provide biotic resistance against the invasion of Morella trees and exotic birds, thus slowing invasion "meltdowns" that disrupt the functioning of native Hawaiian ecosystems.
