“…In reality, many animals adjust their escape strategies based on the identity and/or performance capabilities of the pursuing predator (Bulbert et al, 2015;Eilam, 2005;Fichtel, 2007;Furuichi, 2002;Ilany & Eilam, 2008;Walther, 1969). Similarly, animals will often adopt different anti-predator behaviours and escape responses based on distance to cover, familiarity with the terrain, the predator's proximity and approach speed, how conspicuous the prey feels and in response to social behaviours (Clarke et al, 1993;Cooper, 1997Cooper, , 1998Cooper, , 2009Dill, 1990;Kramer & Bonenfant, 1997;Martin & López, 1995;Quadros et al, 2019). Our model could be modified to investigate different anti-predator, escape or predation strategies based on either biotic or abiotic factors.…”

“…Stegastes spp. territories and their associated algal gardens may cover up to 100% of the benthos on and around branching Acropora colonies (White and O'Donnell 2010;Johnson et al 2011;Quadros et al 2019), and they may significantly alter the algal species present in their territory, reducing growth of larger macroalgae by selectively removing indigestible species (Hata and Kato 2002Ceccarelli et al 2011). Stegastes spp.…”

Outplanting of branching Acropora enhances recolonization of a fish species and protects massive corals from predation

et al. 2021

Damselfish of the genus Stegastes inhabit territories and cultivate algal gardens on branching corals of the genus Acropora, aggressively protecting their territories from other fish and preventing predation upon corals within the territory. This behaviour has important ecological impacts and could also be useful in reducing predation on outplanted corals during reef restoration efforts. However, the degree of protection from predators may depend on the ability of Stegastes spp. to recolonise outplanted or newly established coral colonies. Protection of bleaching-resilient massive corals within territories may be of particular importance due to the role of these corals in maintaining coral cover following bleaching events. This study examined whether the presence of Stegastes spp. reduces predation on the massive bleaching-resilient coral Porites lutea in the Mauritian lagoon, and whether Stegastes spp. readily colonise outplanted branching coral fragments and provide adjacent massive corals with indirect protection from predation. Predation levels on wild-occurring and outplanted P. lutea within and outside Stegastes spp. territories were measured. In addition, Acropora muricata branches were outplanted adjacent to wild P. lutea colonies outside Stegastes spp. territories, and recolonisation of these outplants by Stegastes spp. and the impacts of recolonisation on predation were monitored. Both wild and outplanted P. lutea colonies within Stegastes spp. territories sustained less predation damage compared to colonies outside territories. Stegastes spp. recolonized outplanted A. muricata colonies within six months of outplanting, and in doing so returned predation protection to adjacent P. lutea colonies. The ability of Stegastes spp. to colonise outplanted corals and provide indirect protection to adjacent massive bleaching-resilient corals may inform coral outplanting efforts in systems where Stegastes spp. are common. Encouraging Stegastes spp. recolonisation may help to reduce predation damage to corals within territories and potentially improve the success of rehabilitation efforts.

“…Perhaps, dusky damselfish inhabiting flat rubble are better able to detect intruders, typically seeing them before they penetrated territory boundaries, suggesting that flat territories are easier to patrol than complex patches. It has also been suggested that dusky damselfish on three-dimensional structures exhibit higher levels of boldness, allowing intruders to enter deeper into the territory (Quadros et al 2019). It is possible that dusky damselfish exhibiting a bold personality may tend to occupy territories on boulder corals.…”

“…Clownfishes and damselfishes (Family Pomacentridae) have strong associations to sessile invertebrates, such as corals and sponges. Habitat-bound Pomacentridae fishes are especially important to reef ecology as they exert strong localized environmental effects that profoundly shape their communities, and are therefore regarded as a keystone group (Hixon and Brostoff 1983;Ceccarelli 2007;Di Santo and Lobel 2017;Quadros et al 2019). Clownfishes, for example, actively defend their host-anemone, whereas farming damselfishes cultivate filamentous algal patches that they defend vehemently against intruders and they often reduce large fleshy algae overgrowth of coral (Brawley and Adey 1977).…”

Coral loss alters guarding and farming behavior of a Caribbean damselfish

et al. 2020

Coral loss is a major element of global ecological change in the oceans that may shape the behavior of keystone species such as habitat-attached animals. Farming damselfishes cultivate and aggressively protect algal garden within their territory, thereby shaping local fish assemblages and macro-algae diversity. Following the widespread loss of live branching coral throughout Florida and the Caribbean Sea, dusky damselfish (Stegastes adustus) have modified their territorial behavior. We compared antagonistic behavior, and size and algal species composition of territories of dusky damselfish on dead branching coral rubble and live boulder coral in the Dry Tortugas National Park, USA. Even though similar numbers of "intruders" entered each habitat type, dusky damselfish on rubble territories chased out significantly more fishes, had larger territories and more species of algae were present in their gardens. This study shows that dusky damselfish successfully occupy living and dead coral areas; however, there are potential trade-offs between defending a larger territory and cultivating fewer algal species.
