However, the accuracy of these networks can vary based on construction methods, and there is limited discussion about the true functional roles of species. In this review, I critically evaluate the methodologies and approaches used in 65 studies to construct seed dispersal networks, with a focus on distinguishing between frugivory and effective seed dispersal. In general, I found that most of the studies built the interaction networks based on direct observations of animals eating seeds/fruits (n = 23 studies, 35.38%) and by sampling of scats (n = 18, 27.69%). Data from datasets and by using complementary methods (e.g., DNA-barcoding) accounted for 33.85% (n = 22 studies). Surprisingly, only two studies (3.08%) confirmed seed viability (i.e., if the viability of the dispersed seeds were experimentally confirmed or the microhabitat where the scat had been dropped). This highlights a critical issue: many studies fail to assess all stages of the seed dispersal process (i.e., seed consumption, transport, deposition, and germination). The potential misapplication of the term “seed-dispersal networks” could lead to significant misunderstandings about the true functionality and coevolutionary dynamics of these interactions. Consequently, I advocate for more rigorous methodologies and detailed discussions to improve accuracy about the true functional roles of species within these networks.</div></div>","PeriodicalId":38084,"journal":{"name":"Food Webs","volume":"42 ","pages":"Article e00384"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143137887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, estuarine fish cleaning of parasites has been reported from detailed above-water observations made in eastern Australia and the current study provides additional records of subtropical estuarine fish cleaning relationships based on underwater observation. Specifically, the ubiquitous subtropical estuarine fish, yellowfin bream, <em>Acanthopagrus australis</em> (Sparidae) was observed regularly presenting for parasite cleaning by the common stripey, <em>Microcanthus joyceae</em> (Microcanthidae) in the lower Maroochy River (Queensland, Australia), most notably around morning high tides.

These interactions provide examples of small-bodied fishes with comparable body demarcation (black and yellow bands or stripes) to that of a previously identified fish cleaner (juvenile silver batfish, <em>Monodactylus argenteus</em> (Monodactylidae)) in estuaries, typically servicing clients larger in body size than the cleaners. Interestingly, juveniles of <em>M. argenteus</em> were present but not seen performing cleaning behaviour in the current study.
