“…The typical size used (median diameter = 3.5 mm, median length = 25 mm, n = 34 and n = 39, respectively) was close to the median size of real caterpillars (Novotny & Basset, ). Information was occasionally missing on the colour (González‐Gómez et al ., ; Lluch et al ., ; Moreno & Ferro, ; Poch & Simonetti, ), diameter (González‐Gómez et al ., ; Skoczylas et al ., ; Lluch et al ., ; Poch & Simonetti, ; Molleman & Safian, ; Molleman et al ., ), or length (González‐Gómez et al ., ; Lluch et al ., ) of the artificial caterpillars used.…”

A review of the sentinel prey method as a way of quantifying invertebrate predation under field conditions

Sentinel prey can provide a direct, quantitative measure of predation under field conditions. Live sentinel prey provides more realistic data but rarely allows the partitioning of the total predation pressure; artificial prey is less natural but traces left by different predators are identifiable, making it suitable for comparative studies. We reviewed the available evidence of the use of both types of invertebrate sentinel prey. Fifty-seven papers used real prey, usually measuring predation on a focal (often pest) species, with studies overwhelmingly from North America. The median predation was 25.8% d . Artificial sentinel prey (45 papers) were used in both temperate and tropical areas, placed more above ground than at ground level. The most commonly used artificial prey imitated a caterpillar. Up to 14 predator groups were identified, registering a median of 8.8% d predation; half the studies reported only bird predation. Predation on real prey was higher than on artificial ones, but invertebrate predation was not higher than vertebrate predation. Invertertebrate but not vertebrate predation was negatively related to prey size. Predation near the Equator was not higher than at higher latitudes, nor in cultivated than noncultivated habitats. The use of sentinel prey is not yet standardised in terms of prey size, arrangement, exposure period or data reporting. Due to the simplicity and ease of use of the method, such standardisation may increase the usefulness of comparative studies, contributing to the understanding of the importance and level of predation in various habitats worldwide.

A rich body of theory has been developed to predict the effects of plant diversity on communities at higher trophic levels and the mechanisms underpinning such effects. However, there are currently a number of key gaps in knowledge that have hindered the development of a predictive framework of plant diversity effects on consumers. For instance, we still know very little about how the magnitude of plant trait variation (e.g. intraspecific vs. inter-specific), as well as the identity and combined effects of plant, herbivore and natural enemy traits, mediate plant diversity effects on consumers. Moreover, the fine-scale mechanisms (e.g. changes in consumer behaviour or recruitment responses) underlying such diversity effects in many cases remain elusive or have been overlooked. In addition, most studies of plant diversity effects on associated consumers have been developed under a static, unidirectional (bottom-up) framework of effects on herbivores and predators without taking into account the potential for dynamic feedbacks across trophic levels. Here we seek to address these key gaps in knowledge as well as to capitalize on recent advances and emerging frameworks in plant biodiversity research. In doing so, we provide new insights as well as recommendations which will stimulate new research and advance this field of study. IntroductionThe consequences of plant intra-specific and inter-specific diversity on associated faunas have been the focus of much research over the last decade (e.g. [1 ,2-8,9 ]). Studies have found that plant diversity positively influences arthropod diversity and abundance [3,4,8,10], and alters plant-arthropod and arthropod-arthropod interactions [3,7,11,12]. These findings emphasize that conserving and manipulating plant diversity in natural and managed systems, respectively, is crucial for maintaining ecosystem function [13][14][15].A rich body of theory has been developed to predict the effects of plant diversity on communities at higher trophic levels ([16-22], see Box 1). Despite this vast collection of theory behind plant diversity effects on associated faunas and the large number of empirical studies conducted thus far, formal evaluations of the mechanisms behind the observed patterns have been developed in natural communities (but see [20] for e.g. in agricultural systems). In addition, there are also a number of key gaps in knowledge that have hindered the development of a predictive framework of plant diversity effects on higher trophic levels ( Figure 1). For example, we generally ignore how the magnitude of variation in plant traits (e.g. interspecific vs. intra-specific diversity) or the identity (including independent and interactive effects of multiple traits) of plant traits determines such effects. Similarly, many studies have lacked an explicit evaluation of the influence of herbivore traits such as diet breadth, mobility and feeding behaviour, and the underlying mechanisms for diversity effects on consumer abundance or behaviour remain elusive (e.g. effects of diversit...

“…1). Young plantations comprise poorly developed understory, whereas mature exotic plantations are characterized by the presence of a scattered understory vegetation composed by native shrubs (e.g., Aristotelia chilensis and Chusquea quila), but also by introduced shrubs (e.g., Rubus ulmifolius, Ulex europaeus and Teline monspesulana, see Poch and Simonetti, 2013). Understory vegetation of the native forest includes dead trees and fallen logs, as well as a rich diversity of native shrub species, native tree saplings, mosses, ferns and climbing plants, such as Azara spp., Gevuina avellana, Berberis spp., Blechnum spp., Luma apiculata, Myrceugenia exsucca and C. quila.…”
