“…Our result may reflect the general high density of seagrass found in the Wakatobi MNP and shorter distances between mangrove fringe and adjacent seagrass beds compared to other studies identifying mangrove−seagrass proxi mity as a factor in structuring assemblages (Dorenbosch et al 2004, Jelbart et al 2007). However, studies by Pittman et al (2004) and Meynecke et al (2008) identified that the spatial configuration of Australian mangrove patches (using connectivity indices, e.g. mean nearest neighbour) had strong positive correlations with fish and prawn assemblage density and landings.…”

“…Exceptions include a study that developed predictive maps of fish species richness across the seascape by integrating fish survey data collected in multiple patch types with benthic maps (patch mosaics) and surface complexity from bathymetry (continuous gradients) (Pittman et al 2007). Very few studies have directly quantified seascape connectivity, although it is in creasingly acknowledged as an important process in coastal ecology and for the design of effective management strategies (Gillanders et al 2003, Mumby et al 2004, Ray 2005, Weinstein et al 2005, Meynecke et al 2008, Grober-Dunsmore et al 2009). …”

“…Frost et al 1999, Tanner 2003, Mills & Berkenbusch 2009 on nekton composition and abundance relative to total marsh area, few studies have related nekton density to individual patch size or density, and the documented relationships vary considerably by species. Meynecke et al (2008) provided one of the few comparisons of fish biomass by patch size across a comprehensive sea scape mosaic composed of seagrass, mangrove, marsh, other wetlands, mud, and sand patches (Queensland, Australia). In 1 of their 2 study regions, they found that fish catch was best explained by marsh and wetland patch density.…”

“…Most coastal biogenic habitats exist as components of functionally connected coastal mosaics, so loss or degradation of a particular habitat is likely to impair the integrity of neighboring patches and disrupt links in the ecosystem as a whole. For example, seagrass meadows and salt marshes play a significant role by subsidizing energy to adjacent and even distant ecosystems (Kneib 2000, Guest & Connolly 2006, Heck et al 2008, Meynecke et al 2008. For seagrass-associated species, the spatial arrangement of patches (interpatch distances, contiguity, juxtaposition) can influence important processes such as predator-prey relationships by affecting refuge availability for prey and feeding efficiency for predators, and rate of movement between their habitats (Irlandi & Crawford 1997, Micheli & Peterson 1999, Grober-Dunsmore et al 2007).…”

We review the progress made in the emerging field of coastal seascape ecology, i.e. the application of landscape ecology concepts and techniques to the coastal marine environment. Since the early 1990s, the landscape ecology approach has been applied in several coastal subtidal and intertidal biogenic habitats across a range of spatial scales. Emerging evidence indicates that animals in these seascapes respond to the structure of patches and patch mosaics in different ways and at different spatial scales, yet we still know very little about the ecological significance of these relationships and the consequences of change in seascape patterning for ecosystem functioning and overall biodiversity. Ecological interactions that occur within patches and among different types of patches (or seascapes) are likely to be critically important in maintaining primary and secondary production, trophic transfer, biodiversity, coastal protection, and supporting a wealth of ecosystem goods and services. We review faunal responses to patch and seascape structure, including effects of fragmentation on 5 focal habitats: seagrass meadows, salt marshes, coral reefs, mangrove forests, and oyster reefs. Extrapolating and generalizing spatial relationships between ecological patterns and processes across scales remains a significant challenge, and we show that there are major gaps in our understanding of these relationships. Filling these gaps will be crucial for managing and responding to an inevitably changing coastal environment. We show that critical ecological thresholds exist in the structural patterning of biogenic ecosystems that, when exceeded, cause abrupt shifts in the distribution and abundance of organisms. A better understanding of faunal-seascape relationships, including the identifications of threshold effects, is urgently needed to support the development of more effective and holistic management actions in restoration, site prioritization, and forecasting the impacts of environmental change.

“…For estuarine fish, the most obvious outcome is a loss of available habitat. This is especially consequential for fish that use estuarine habitats as a nursery ground during their juvenile stages of development -of which there are many Australian species (Gillanders et al 2003;Meynecke et al 2008). Estuarine fish may also be indirectly affected through changes in trophic cascades.…”

Abstract. One of the most obvious and expected impacts of climate change is a shift in the distributional range of organisms, which could have considerable ecological and economic consequences. Australian waters are hotspots for climate-induced environmental changes; here, we review these potential changes and their apparent and potential implications for freshwater, estuarine and marine fish. Our meta-analysis detected ,300 papers globally on 'fish' and 'range shifts', with ,7% being from Australia. Of the Australian papers, only one study exhibited definitive evidence of climate-induced range shifts, with most studies focussing instead on future predictions. There was little consensus in the literature regarding the definition of 'range', largely because of populations having distributions that fluctuate regularly. For example, many marine populations have broad dispersal of offspring (causing vagrancy). Similarly, in freshwater and estuarine systems, regular environmental changes (e.g. seasonal, ENSO cycles -not related to climate change) cause expansion and contraction of populations, which confounds efforts to detect range 'shifts'. We found that increases in water temperature, reduced freshwater flows and changes in ocean currents are likely to be the key drivers of climateinduced range shifts in Australian fishes. Although large-scale frequent and rigorous direct surveys of fishes across their entire distributional ranges, especially at range edges, will be essential to detect range shifts of fishes in response to climate change, we suggest careful co-opting of fisheries, museum and other regional databases as a potential, but imperfect alternative.
