Data from: Arthropods as vertebrate predators: a review of global patterns
<p>Aim: Arthropods as vertebrate predators is generally overlooked in ecology due to the cryptic nature of these events, the relatively small size of arthropods, and the difficulty in finding published data. This study represents the largest global assessment of arthropods preying on vertebrates to provide a conceptual framework, identify global patterns, and provide a searchable database.</p> <p>Location: Global. Time period: Present. Major taxa studied: Arthropods and vertebrates.</p> <p>Methods: A systematic literature review was conducted.</p> <p>Results: Nearly 1300 recorded observations were collated from 89 countries. Arthropod predators were from six classes and 80 families. Vertebrate prey were from five classes and 162 families. Spiders represented over half of all predatory events and were the main predator for all vertebrates except birds, which were preyed mostly upon by praying mantises. Over a third of all prey were amphibians, specifically frogs. Preyed reptiles were nearly all lizards, half of mammal prey were bats, nearly a third of fish were Cypriniformes, and half of bird prey were passerines. Predation by spiders were mainly documented from the U.S., Brazil, and Australia, and biased everywhere except the U.S.; insects were mainly from Europe, Australia, and the Americas, and biased toward North America; Amphibian events were mainly from the Americas and strongly biased everywhere, except for the U.S. and Australia; reptiles were mostly from the Americas and Australia, and biased towards the U.S. and Australia; birds were mainly from the Americas, Australia, and Europe, and biased towards Central America and Europe; mammals were mostly reported from North and Central America, Australia, and Asia, and strongly biased everywhere except Brazil.</p> <p>Main conclusions: This study demonstrates that arthropods are an underestimated predator of vertebrates. Recognizing and quantifying these predator-prey interactions is vital for identifying patterns and the potential impact of these relationships on shaping vertebrate populations and communities.</p>

Data from: Effects of food abundance and early clutch predation on reproductive timing in a high Arctic shorebird exposed to advancements in arthropod abundance
Climate change may influence the phenology of organisms unequally across trophic levels and thus lead to phenological mismatches between predators and prey. In cases where prey availability peaks before reproducing predators reach maximal prey demand, any negative fitness consequences would selectively favor resynchronization by earlier starts of the reproductive activities of the predators. At a study site in northeast Greenland, over a period of 17 years, the median emergence of the invertebrate prey of Sanderling Calidris alba advanced with 1.27 days per year. Yet, over the same period Sanderling did not advance hatching date. Thus, Sanderlings increasingly hatched after their prey was maximally abundant. Surprisingly, the phenological mismatches did not affect chick growth, but the interaction of the annual width and height of the peak in food abundance did. Chicks grew especially better in years when the food peak was broad. Sanderling clutches were most likely to be depredated early in the season, which should delay reproduction. We propose that high early clutch predation may favor a later reproductive timing. Additionally, our data suggest that in most years food was still abundant after the median date of emergence, which may explain why Sanderlings did not advance breeding along with the advances in arthropod phenology.
Data from: Arthropod but not bird predation in Ethiopian homegardens is higher in tree-poor than in tree-rich landscapes
Bird and arthropod predation is often associated with natural pest control in agricultural landscapes, but the rates of predation may vary with the amount of tree cover or other environmental factors. We examined bird and arthropod predation in three tree-rich and three tree-poor landscapes across southwestern Ethiopia. Within each landscape we selected three tree-rich and three tree-poor homegardens in which we recorded the number of tree species and tree stems within 100 × 100 m surrounding the central house. To estimate predation rates, we attached plasticine caterpillars on leaves of two coffee and two avocado shrubs in each homegarden, and recorded the number of attacked caterpillars for 7–9 consecutive weeks. The overall mean daily predation rate was 1.45% for birds and 1.60% for arthropods. The rates of arthropod predation varied among landscapes and were higher in tree-poor landscapes. There was no such difference for birds. Within landscapes, predation rates from birds and arthropods did not vary between tree-rich and tree-poor homegardens in either tree-rich or tree-poor landscapes. The most surprising result was the lack of response by birds to tree cover at either spatial scale. Our results suggest that in tree-poor landscapes there are still enough non-crop habitats to support predatory arthropods and birds to deliver strong top-down effect on crop pests.
Data from: A meta-analysis of non-consumptive predator effects in arthropods: the influence of organismal and environmental characteristics
Non-consumptive effects (NCEs) – changes in prey behavior or physiology in response to predator threat – are common and can be as strong as consumptive effects. However, our knowledge of NCEs in arthropod systems is lacking. Factors related to study organism and environment have the potential to influence the occurrence and magnitude of NCEs in arthropod systems. While factors such as coevolutionary history of natural enemies and their prey, predator cue, predator or prey feeding mode, and refuge availability have been theoretically and empirically examined, no trends have been proposed for arthropods. We compiled 62 studies, yielding 128 predator–prey interactions, which explicitly examined NCEs in experiments where arthropods were identified to species, using a previously published database of papers from 1990 to 2005 and a new database of papers published from 2006 to 2015. Using these data, we conducted a meta-analysis to explore the influence of organismal and environmental characteristics on the magnitude of predator NCEs. Our analysis addressed the following three questions. 1) Does predator–prey coevolution give rise to stronger NCEs than when predator and prey species did not coevolve? 2) What influence does habitat type and refuge availability have on NCEs? 3) How do predator characteristics (cue type, hunting mode and life stage) and prey characteristics (mobility, life stage, specialization, gregariousness and feeding mode) influence NCEs? We found that while NCEs were similar across most measured characteristics, NCEs on prey activity were significantly stronger when predator and prey shared an evolutionary history. Our results support growing evidence that NCEs have a negative effect on prey traits and that behavioral NCEs are stronger than physiological ones. Additional studies are needed to be confident in any emerging patterns, therefore we identify key gaps in the literature on NCEs in arthropod systems and discuss ideas for moving forward.

Opposite latitudinal patterns for bird and arthropod predation revealed in the experiments with differently colored artificial prey
<p>The strength of biotic interactions is generally thought to increase towards the equator, but support for this hypothesis is contradictory. We explored whether predator attacks on artificial prey of eight different colours vary among climates and whether this variation affects the detection of latitudinal patterns in predation. The data set provides number of damage marks on each of 1320 plasticine caterpillars of eight different colours, which were attached to branches of woody plants and exposed from 10 to 118 days in 11 localities across the globe. During each record, all marks found on model caterpillars were attributed to a certain group of predators (birds, arthropods, mammals and other predators), and marks of each type were counted. The models that had damage marks were remoulded or replaced if the damage was severe. These data contribute to our understanding of macroecological patterns in biotic interactions.</p>
