Thereby, supplementing empirical, taxonomy-based information on trophic links with trait-based inference may help us build more realistic and adaptable food webs. Here, we go beyond taxonomy to document (i) how traits (e.g., body size, metabolic category and feeding strategy) contribute to local food web structure, and (ii) how associations of consumer-resource traits are structured. We built a trophic-link based trait-interaction network—or trait web—by combining multivariate approaches and network analysis. We found that consumer-resource associations organize into trait profiles that reflect the general vertical structure of the food web, as well as identify groups of limited sets of highly interacting traits.

Similarly, loss of food to fear effects and interspecific interactions can influence energetic costs and consumption rates. Due to their smaller body size and predominantly solitary nature, cheetahs (<em>Acinonyx jubatus</em>) are particularly prone to negative, direct interactions with competing carnivores, and they frequently lose kills to apex predators. However, trophic interactions with other species may have been underreported in the literature. Here, we document anecdotal interactions between cheetah and baboon (<em>Papio</em> spp.) species, across multiple sites in Africa, where baboon troops chased cheetahs off their kills and, in some cases, fed on the remaining carcasses. Given the widespread distribution, and relatively high densities of baboon species across sub-Saharan Africa, we hypothesise that these interactions are likely to be underrepresented in the literature. Since cheetah already experience high levels of competition with apex predators, particularly in South African fenced reserves where competing carnivores are often stocked at densities approaching, or in some cases exceeding, carrying capacity, additional competition and the loss of prey to baboons could further increase predation rates and have implications for reserve management. Baboons are often defensive around large carnivores. As such, interactions with cheetahs are likely to be motivated primarily as a defensive strategy. We encourage further research into food loss, kleptoparasitic behaviour and other competitive interactions between cheetah and <em>Papio</em> species.</p></div>","PeriodicalId":38084,"journal":{"name":"Food Webs","volume":"38 ","pages":"Article e00331"},"PeriodicalIF":1.7,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352249623000605/pdfft?md5=138ea25ad0adb0a033c2e5509eb012c5&pid=1-s2.0-S2352249623000605-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138987066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-consumptive effects (NCEs) are well documented across prey taxa in response to different predator cues. However, for most prey species, both the mechanisms underlying NCEs and the impacts of NCEs on broader ecological processes are poorly understood. We addressed these knowledge gaps for an aphid prey species (<em>Myzus persicae</em>) by studying dispersal, in-leaf feeding behavior, and plant virus transmission in response to chemical cues deposited by a walking predator (<em>Hippodamia convergens</em>), a non-predator, non-competitor (<em>Drosophila melanogaster</em>), and an artificial feeding deterrent (2% mineral oil). We used this approach to better understand the specificity of <em>M. persicae</em> responses to chemical footprints of threatening and non-threatening organisms, as well as the magnitude of behavioral responses relative to a known deterrent. We found that chemical footprints deposited by <em>H. convergens</em> stimulated <em>M. persicae</em> to disperse from a suitable host (<em>Brassica napus</em>) at a rate equivalent to the 2% mineral oil positive control, while footprints of <em>D. melanogaster</em> did not modify <em>M. persicae</em> dispersal. Through electrical penetration graphing (EPG) recordings, we found that mineral oil stimulated aphids to make more probes, but footprint treatments did not significantly modify feeding behavior. In mesocosm-based virus transmission assays, <em>H. convergens</em> footprints and 2% mineral oil also stimulated increased dispersal, but this did not translate into increased transmission of turnip mosaic virus. We identified components of <em>H. convergens</em> and <em>D. melanogaster</em> footprints using gas chromatography and mass spectrometry and found that <em>H. convergens</em> footprints are chemically similar to footprints of related Coccinellidae, but distinct from <em>D. melanogaster</em> footprints. Our results provide evidence of specificity in <em>M. persicae</em> responses to predator footprints, which may help this prey species avoid costly dispersal behavior in response to cues from non-predators. We also provide ecological context by demonstrating that increased dispersal in response to predator cues does not always lead to increased virus transmission, as previously assumed, particularly when in-leaf feeding behaviors underlying virus acquisition do not change in response to predator cues.</p></div>","PeriodicalId":38084,"journal":{"name":"Food Webs","volume":"37 ","pages":"Article e00325"},"PeriodicalIF":1.7,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S235224962300054X/pdfft?md5=f4034ce03df7e202830b0bd0fc21956d&pid=1-s2.0-S235224962300054X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92024589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
