Faunal complexity is an impediment to understanding the function of fragmented coastal wetlands. Conceiving faunal communities as part of a larger network of communities (or a metacommunity) helps to resolve this complexity by enabling simultaneous consideration of local environmental influences and 'regional' dispersal-driven processes. We assessed the role of local vs. regional factors on the fish assemblage structure of a wetland system comprising 20 tidal pools. In equivalent freshwater…

Bottom-up control regulates patterns of fish connectivity and assemblage structure in coastal wetlands

TLDR
Strong and inter-annually consistent spatial concordances among the 3 faunal components are found, characterised by higher densities of benthic invertebrates and zooplankton in pools at lower elevations on the salt-marsh and bottom-up forcing acting across 3 trophic levels.

Local Habitat and Seascape Structure Influence Seagrass Fish Assemblages in the Venice Lagoon: The Importance of Conservation at Multiple Spatial Scales

Seagrass meadows are a critical component of estuarine and coastal seascapes, and their structure influences fish assemblages at multiple spatial scales. The patch mosaic model, which defines the

Seascape heterogeneity modifies estuarine fish assemblages in mangrove forests

Mangroves are a dominant structural habitat within tropical and subtropical estuaries that provide a number of ecosystem services, including habitat for a range of crustaceans and fish. However,

The Nekton Assemblage of Salt Marsh Pools in a Southeastern United States Estuary

Marsh pools are present in estuaries throughout the world and provide valuable habitat for fishes and decapod crustaceans (i.e., nekton). The purpose of our study was to examine the species

Seascape Configuration Influences the Community Structure of Marsh Nekton

Around the globe, salt marsh ecosystems are rapidly changing, leading to alterations in both the amount, and configuration of marsh habitats. Sea level rise is a key driver of salt marsh change and

Shellfish Reefs Increase Water Storage Capacity on Intertidal Flats Over Extensive Spatial Scales

Ecosystem engineering species can affect their environment at multiple spatial scales, from the local scale up to a significant distance, by indirectly affecting the surrounding habitats. Structural

Nekton Use of Flooded Salt Marsh and an Assessment of Intertidal Creek Pools as Low-Tide Refuges

Patterns of nekton occurrence on the salt marsh surface at high tide and in an adjacent intertidal creek pool at low tide were used to investigate movements of nekton in an intertidal basin. Paired

Dendritic network structure constrains metacommunity properties in riverine ecosystems.

TLDR
The findings demonstrate that the balance of local and regional effects changes depending on location within riverine network with local (environmental) factors dictating community structure in headwaters, and regional (dispersal driven) forces dominating in mainstems.

Fish Utilisation of Wetland Nurseries with Complex Hydrological Connectivity

TLDR
The nature and diversity of temporal utilisation patterns at a species or genus level over three annual cycles in a tropical Australian estuarine wetland system are examined to understand the patterns and subsequent processes driving fish assemblage structure in such wetlands.

We review the progress made in the emerging field of coastal seascape ecology, i.e. the ap- plication of landscape ecology concepts and techniques to the coastal marine environment. Since the early

Freshwater fishes of the Burdekin River, Australia: biogeography, history and spatial variation in community structure

Spatial variation in freshwater fish community structure in a large, structurally monotonous sub-tropical Australian river over 1989–1992 is described. The number of species collected (25) over the

Hydrological connectivity structures concordant plant and animal assemblages according to niche rather than dispersal processes

TLDR
Two environmental factors, flow regime and channel width, explained significant proportions of variation in all three assemblages, potentially contributing to the observed spatial concordance between them and representing local environmental gradients along which these communities re-assemble after the wet season, according to niche rather than dispersal processes.

Temporal dynamics of fish assemblages of natural and artificial tropical estuaries

We sampled the fish fauna of 9 small natural estuaries and 2 constructed estuarine lakes in Australia’s dry tropics over 15 mo to detail the dynamics of fish assembly structures over time. The

Tropical estuarine fish assemblages often show characteristic spatial variation at the scale of individual estuaries but there is no clear grouping of estuaries based on variables such as proximity

The seascape nursery: a novel spatial approach to identify and manage nurseries for coastal marine fauna

TLDR
A novel approach for assigning nursery areas for mobile fauna that incorporates critical ecological habitat linkages is proposed and the term 'seascape nurseries' is introduced which conceptualizes a nursery as a spatially-explicit seascape consisting of multiple mosaics of habitat patches that are functionally connected.
