Lower trophic levels and detrital biomass control the Bay of Biscay continental shelf food web: Implications for ecosystem management (2011, background): “Previous models of the Bay of Biscay (‘‘Biscaya 1970’’, ‘‘Biscaya 1998’’ (Ainsworth et al., 2001) and ‘‘Cantabrian Sea 1994’’ (Sanchez and Olaso, 2004)) were included in the comparative study of Libralato et al. (2006).”
Keystone species: toward an operational concept for marine biodiversity conservation (2015, methodology): “In fact, most models were included in the meta-analysis introducing the KS2 index (Libralato et al. 2006), or had the latter index applied by their authors, while four models had alternative original methods proposed by the modelers applied (Aydin et al. 2002, Kitchell et al. 2002, Okey et al.…”
Assessing the trophic position and ecological role of squids in marine ecosystems by means of food-web models (2013, methodology): “Keystoneness index 1 (KS1) showed a mean value of &0.3270.27 and a range from 0.07 (most keystone) to &1.14 (least keystone).”
Predicting ecological consequences of marine top predator declines. (2008, background): “tropics and subtropics) and marine mammals (in temperate and subpolar areas) are the most commonly identified keystone species groups, each with a top rank in 18% of cases [ 60 ].”
Jellyfish in ecosystems, online databases, and ecosystem models (2008, methodology): “In response to this, Libralato et al. (2006) developed a modeling approach to investigate this concept based on the mutual impact matrix of EwE (see above).”
Behavioural drivers of the ecological roles and importance of marine mammals (2015, background): “Given the potential top-down impacts of marine mammals on their prey (e.g. Bowen 1997, Libralato et al. 2006, Roman et al. 2014), further work on links between marine mammal behavioural decisions and community and ecosystem dynamics is important for gaining a functional understanding of these many…”
Global overview of the applications of the Ecopath with Ecosim modeling approach using the EcoBase models repository (2015, methodology): “The methodology was implemented based on two indices of keystoneness proposed in the literature: KS#1 (Libralato et al., 2006) and KS#2 (adapted from Power et al., 1996), both based on a consensus definition of keystone species (Christensen et al., 2008).”
Unravelling the ecological role and trophic relationships of uncommon and threatened elasmobranchs in the western Mediterranean Sea (2015, background): “Elasmobranch fishes are usually considered keystone species in marine environments, due to their role in maintaining the structure and functioning of food webs (Libralato et al. 2006, Baum & Worm 2009).”
Modeling What We Sample and Sampling What We Model: Challenges for Zooplankton Model Assessment (2017, background): “In a review of 41 Ecopath models, (Libralato et al., 2006) found that zooplankton (including Euphausiids) had high “keystoneness” (i.”
Topological analysis of the ecological importance of elasmobranch fishes: A food web study on the Gulf of Tortugas, Colombia (2010, background): “, quantification of the functional importance of species in a community (Libralato et al., 2006), to study the effect of a predator on the population size of its prey, or, in some very specific cases, on trophic cascade effects that do not consider other types of indirect effects (e.”
Diet of Engraulis encrasicolus in the northern Adriatic Sea (Mediterranean): ontogenetic changes and feeding selectivity (2009, background): “Moreover, anchovy was found (Coll et al. 2007) to be one of the keystone species within the Adriatic ecosystem when applying the index proposed by Libralato et al. (2006) based on the total mixed trophic impacts of the food web.”
Benthic and fish aggregation inside an offshore wind farm: Which effects on the trophic web functioning? (2017, methodology): “Calculations were made according to the index defined by 390 Libralato et al. (2006).”
Food-web structure of and fishing impacts on the Gulf of Cadiz ecosystem (South-western Spain) (2013, background): “Since this vulnerable group has been declining in most ecosystems it could be used as an ecological indicator to monitor fishing impact (Librarato et al., 2006).”
