“…Temporal variability of fish assemblages at different scales can be quite large and may 335 confound spatial patterns of fish among different habitats (Connell & Kingsford, 1998). In this study, the relative abundances of species fluctuated over the three sampling times.…”

In the marine environment, artificial structures are not, in general, managed for their value as habitat and are often built with no a priori expectation as to the assemblages which 10 may colonise them. It may, however, become increasingly important to consider the value of such structures as habitat when decisions are made with respect to the management of artificial structures. This study investigates the role marinas play as habitat for fish by examining the distribution of fish associated with these urban developments and how this distribution relates to

“…Heterogeneity at small scale (tens of metres) is increasingly emerging as an ubiquitous feature of reef fishes. It was documented in the last decades by studies, in most cases even encompassing a larger extent and more numerous scales than the present one, in New Zealand [30, see also 83 for a review], Australia [29,37,39,71], Aleutian Archipelago [84], Mexican Caribbean coast [85] and the Mediterranean Sea [31,86]. This can be explained considering that several tropical [87][88][89] and temperate [45,[90][91][92] reef fish species show home ranges that, though changing over their life-cycles, are within a few thousand m 2 or even confined to less than 10 m 2 .…”

“…There is evidence, however, that temporal variation of adult reef fishes is much smaller than spatial variation, at least on scales ranging from days and weeks to months, and as long as crepuscular periods are avoided [103,104]. In spite of the mentioned limitations, the present discussion on spatial patterns of the studied fish assemblages is built on the notion that variability in space (from metres to tens up to 100 km) is often more important than variability in time (weeks to months and even years), especially when response variables are examined at the assemblage level [29,30,32,37,71].…”

“…The availability, within each site, of replicate reefs sampled in both the 'cool' and the 'warm' period reported for the study region [73] allowed to reduce, but not to fully remove, such a confounding effect. Indeed, reef-associated fish assemblages may respond to environmental conditions with changes in abundance not just at different spatial scales, but also at a range of temporal scales [29][30][31][32]. For instance, oceanographic differences can drive seasonal patterns of fish recruitment differing between adjacent islands within the same archipelago [102].…”

“…Larger-scale variation in the structure and dynamics of reef communities, instead, may depend on factors such as differences in wave exposure [26] or food and propagule supply [27,28]. Reef-associated fish assemblages, in particular, vary in abundance and diversity in response to variability in environmental conditions over a range of scales [29][30][31][32][33]. These may include the variability of oceanographic conditions as driver of fish variation at spatial scales of hundreds of kilometres or more [34,35], and the physical structure of the reef as driver of fish variation at scales from metres to some kilometres [36].…”

Spatial variation of reef fishes and the relative influence of biotic and abiotic habitat traits

2017

Patterns of distribution of reef fishes were examined across three spatial scales and related to habitat traits along 25 km of the northern Portuguese coast. Response variables included the multivariate assemblage structure, the total number of taxa and individuals, and the abundance of single groups categorized according to their preference for the benthic, proximo-benthic or pelagic environment, feeding and reproductive behaviour. Habitat traits included topographic elements (small and large 'drops' like cracks and crevices) and the extent of dominant morpho-functional types of macroalgae (kelp, large foliose, small erect, turf-forming filamentous, and encrusting). All fish responses were characterized by the largest variance at the smallest scale (among transects tens m apart), followed by that among reefs (hundreds m to 1 km apart) and almost null variance among sites (some km apart). Small and large 'drops' of the substratum explained, respectively, considerable variation of assemblage structure and the total abundance of individuals, while the extent of bare rock influenced the richness of taxa and that of benthic fishes, fishes feeding on sessile invertebrates and fishes laying benthic eggs or having nesting behaviour. Combinations of abiotic and biotic structural attributes of reefs influenced proximo-benthic fishes, the predators of mobile animals and fishes releasing pelagic eggs. The here reported associations between patterns of distribution of reef fishes and habitat traits have implications for the design of future protection schemes suitable to guarantee the conservation of reef fish communities and of the processes responsible for their variation. Within the SLOSS (single-large vs. several-small) debate in the design of marine reserves, for example, effective protection to the studied reef fishes would be provided by a set of small reserves, rather than a single large which might be appropriate for fishes having wider home ranges.

ABSTRACT1. The Solitary Islands Marine Park (SIMP) in New South Wales (NSW), Australia, is located in a tropicaltemperate biotone, with variable influence of the tropical East Australian Current (EAC) from inshore to offshore. Marine communities on the extensive, subtidal, rocky reefs are poorly described. As a result, the current Habitat Classification System (HCS) used as part of the process to determine the marine park zoning arrangements, which places all shallow reef (o25 m) in the same category, is unlikely to represent real biotic patterns.2. To evaluate the influence of five key factors (distance from shore, reef type, dominant benthos, latitude, and depth range) fish assemblages were widely surveyed, using 30-minute timed counts, at 68 sites across the extent of shallow reef within the park. Relationships between assemblage patterns and levels of the different factors were subsequently examined using multivariate analyses.3. Patterns of reef fish assemblages were most strongly correlated with distance from shore. Three distinct assemblages occurred on inshore (o1.5 km), mid-shelf (1.5-6 km), and offshore (46 km) reefs. Differences in assemblage structure by reef type were also apparent on inshore and offshore reefs, but not on mid-shelf reefs. Correlations with the other factors were weak. The cross-shelf pattern was persistent over the scale of years.4. The results of the study provide strong support for incorporating distance-from-shore categories into a refined HCS. This will improve its ability to represent biological diversity as reflected by patterns of reef fish assemblages. Further research is required to determine the wider application of the HCS to other marine parks in NSW and to determine if it also, effectively, represents other components of biodiversity.
