“…Stomach content analyses can be done in tandem with stable isotope analyses to further elucidate the trophic structure of the community in question (Fry 2006). These analyses typically use relative values of d 15 N, a stable isotope that accumulates in the tissues of consumers, to create a more detailed and time-integrated measure of trophic position and, subsequently, guild membership (Lee et al 2019). Carbon stable isotope ratios can also be used to determine the relative contribution of various basal resources to different trophic groups, providing a better understanding of energy flow through the food web (e.g., Malek et al 2016).…”

A major strength of the guild approach is its ability to simplify community analysis by aggregating species with similar roles or functions into groups. These groups can be used to study a number of important ecological concepts, including functional diversity, community response to disturbance, and food-web dynamics. Despite increased use, guild membership can be based on subjective criteria that are arbitrarily chosen, leading to inconsistencies across studies. Additionally, studies using the guild approach generally ignore ontogenetic changes in diet and habitat use and therefore, do not fully capture the complexity of aquatic communities. Although these issues have been discussed in the literature, much has changed since the last review was published a decade ago. In our examination, we discuss data requirements and consequences of data availability and reliability on guild formation. We identify bootstrapping and permutation techniques developed to address limitations through cluster validation and the identification of ontogenetic shifts prior to guild delineation. Lastly, we provide a step-by-step guide to guild analysis, accompanied by a decision tree, to facilitate objective and informed guild creation.

“…The local climate is dictated by the northeast monsoon (November to March) and the southwest monsoon (May to September) which are separated by two short periods of variable weather conditions, the inter-monsoon periods in April and October respectively. Mangrove forests (12,723 ha) and coastal mudflats (12,360 ha) are the main coastal habitats along the Klang Strait, which had variably suffered losses from extirpation or reclamation due to rapid coastal development, port expansion, and industrial activities (MPP-EAS 1999;Sasekumar et al 2012;Lee et al 2019). The coal-, oil-and gas-fired, 2420 MW Kapar Power Station (KPS) commissioned for operation in 1987 attests to the burgeoning energy demand for development in the Klang hinterland (Azila and Chong 2010).…”

“…Studies examining the dietary composition of fish in Malaysia focus mainly on juvenile and adult fish (e.g. Chew et al 2012;Lee et al 2019) and only a few concerning fish larvae (Ara et al 2013). This is because more tedious work and skills are required for the enumeration of microscopic food items in larval fish (Robert et al 2014).…”

Does structural change in the zooplankton community affect larval fish feeding in anthropogenically disturbed tropical waters?

[2013][2014] were analysed for their dietary composition. Despite the dramatic replacements of zooplankton taxa due to escalating anthropogenic disturbances, the dominant copepod families, Paracalanidae, Oithonidae and Euterpinidae, remain the major prey for fish larvae. Dietary shifts in prey composition from before to after impact depend on the larval fish family and their ontogenetic stage. Dietary changes are observed in the Bregmacerotidae, Engraulidae, Gobiidae and Sciaenidae that opportunistically feed on the small-bodied copepods (oithonids and Parvocalanus crassirostris), whereas the Callionymidae, Clupeidae and Cynoglossidae naturally feed on these copepods even before these prey become numerically dominant with anthropogenic disturbance. There is no dietary shift in the Leiognathidae, exceptional in that they are specialists feeding mainly on detritus and polychaete larvae. Since the bottom-up effects are not comprehensive among fish families and dietary plasticity is evident, it is postulated that only the intolerant or non-adaptable larval species are adversely affected by the environmental perturbations.
