“…Predatory swimming crabs might have also been attracted by thick layers of the blue mussel (Mytilus edulis) in the shallow water sections of the platform (Krone et al, 2013). Dense aggregations of mussels provide habitat for diverse assemblages of associated faunal communities (Saier, 2002;Firstater et al, 2011) which are a valuable food sources for predatory decapods (Freire and González-Gurriarán, 1995).…”

Within the next few decades, large underwater structures of thousands of wind turbines in the northern European shelf seas will substantially increase the amount of habitat available for mobile demersal megafauna. As a first indication of the possible effects of this large scale habitat creation on faunal stocks settling on hard substrata, we compared selected taxa of the mobile demersal megafauna (decapods and fish) associated with the foundation of an offshore research platform (a wind-power foundation equivalent) with those of five shipwrecks and different areas of soft bottoms in the southern German Bight, North Sea. When comparing the amount of approximately 5000 planned wind-power foundations (covering 5.1 Â 10 6 m 2 of bottom area) with the existing number of at least 1000 shipwrecks (covering 1.2 Â 10 6 m 2 of bottom area), it becomes clear that the southern North Sea will provide about 4.3 times more available artificial hard substratum habitats than currently available. With regard to the fauna found on shipwrecks, on soft substrata and on the investigated wind-power foundation, we predict that the amount of added hard substrata will allow the stocks of substrata-limited mobile demersal hard bottom species to increase by 25e165% in that area. The fauna found at the offshore platform foundations is very similar to that at shipwrecks. Megafauna abundances at the foundations, however, are lower compared to those at the highly fractured wrecks and are irregularly scattered over the foundations. The upper regions of the platform construction (5 and 15 m depth) were only sparsely colonized by mobile fauna, the anchorages, however, more densely. The faunal assemblages from the shipwrecks and the foundations, respectively, as well as from the soft bottoms clearly differed from each other. We predict that new wind-power foundations will support the spread of hard bottom fauna into soft bottom areas with low wreck densities.

“…However, other studies suggest that herbivores can have a strong effect in temperate latitudes and a weaker effect in the tropics (Poore et al., ; Vinueza et al., ). Manipulative field experiments considering different upwelling or nutrient conditions in the range considered in this review showed that herbivory can vary according to productivity levels (Firstater et al., ; Hidalgo et al., ; Nielsen & Navarrete, ) and microhabitat use (Firstater et al., ) with no marked trends in latitudinal patterns, and thus, the role of top‐down versus bottom‐up drivers would be context‐dependent (see also Vinueza et al., ). This may be due to differences in oceanographic regimes and consumer composition at different localities, and field experimental studies should progress further to incorporate this variability in their designs.…”

“…It seems that the strong emphasis in field experimental‐based methods developed during 1970s and 1980s (Castilla, ) has motivated a new generation of experimental ecologists in Chile, which may explain the higher number of experimental studies found in the last decade. An important number of studies have been conducted recently (2008 to present) in Peru (around 10°S; Hidalgo et al., ; Firstater et al., ; Firstater, Hidalgo, Lomovasky, & Iribarne, ), which could also motivate the development of marine field experimental research at these latitudes. Interestingly, most field manipulative studies conducted in Ecuador (Galápagos Islands) and Peru report international funding and/or were conducted by non‐native researchers (i.e., reporting foreign associated institutions).…”

Ecological manipulative experiments conducted in marine coastal ecosystems have substantially improved ecological theory during the last decades and have provided useful knowledge for the management and conservation of coastal ecosystems. Although different studies report global trends in ecological patterns worldwide, Southeastern Pacific coastal ecosystems have been poorly considered. Given that the SE Pacific coast encompasses diverse coastal ecosystems, consideration of studies conducted along this range can shed light on the heterogeneity of processes regulating coastal communities. We reviewed the biotic interactions and habitat type considered, as well as the complexity in terms of spatial and temporal extent of manipulative field experimental studies conducted along the SE Pacific coast from 0°S to 56°S (Ecuador to Chile). We test the effect of funding reported by different studies as a main factor limiting experimental complexity. From field ecological studies published from 1970 to 2016, we found that 81 studies were truly manipulative, in which one or multiple factors were “manipulated.” Around 77% of these studies were located between 21°S and 40°S, and conducted in intertidal rocky habitats. An increase in experimental studies was observed between 2010 and 2015, especially focused on herbivore–alga interactions, although we found that both the temporal extent and spatial extent of these studies have shown a decrease in recent decades. Funding grant amount reported had a positive effect on elapsed time of field experiments, but no effect was observed on spatial extent or in the biotic interactions considered. Elapsed time of experiments was different among the main biotic interactions considered, that is, herbivory, predation, and competition. We suggest that to further progress in applied ecological knowledge, it will be necessary to consider pollution and urbanization processes explicitly using a field experimental framework. This information could improve our understanding of how ecosystems present along the SE Pacific coast respond to climate change and increased levels of human interventions.

“…In addition, the extensive root systems of mangroves create habitat heterogeneity and complexity, offering suitable foraging sites for juvenile fishes and protecting them from predators by reducing their visibility [32,33]. Habitat heterogeneity and complexity is a major factor that influences fauna diversity and distribution [6,[41][42][43].…”

Mangrove is an evergreen, salt tolerant plant community, which grows in inter-tidal coastal zones of tropical and subtropical regions of the world. They are ecologically important for many fauna species and are rich in food resources and consist of many different vegetation structures. They serve as ideal foraging and nursery grounds for a wide array of species such as birds, mammals, reptiles, fishes and aquatic invertebrates. In spite of their crucial role, around 50% of mangrove habitats have been lost and degraded in the past two decades. The fauna diversity of mangrove habitat at Marudu Bay, Sabah, East Malaysia was examined using various methods: i.e. aquatic invertebrates by swap nets, fish by angling rods and cast nets, reptiles, birds, and mammals through direct sighting. The result showed that Marudu Bay mangrove habitats harbored a diversity of fauna species including 22 aquatic invertebrate species (encompassing 11 crustacean species, six mollusk species and four worm species), 36 fish species, 74 bird species, four reptile species, and four mammal species. The wide array of fauna species could be due to the availability of complex vegetation structures, sheltered beaches and tidal mudflats, which are rich in food resources and also offer safe foraging and breeding grounds for them. These heterogeneous habitats must be protected in a sustainable way in order to ensure the continued presence of aquatic and terrestrial fauna species for future generations.
