“…Apart from direct effects (e.g., mortality), predators indirectly affect the morphology (e.g., Relyea et al 2021;Sergio et al 2021), life history (e.g., Lent and Babbitt 2020;Najafi et al 2021), and physiology (e.g., Joshi et al 2017;Florencio et al 2020) of prey. Predators may also modify the behavior of preys by reducing foraging (Rae and Murray 2019;Mamede and Nomura 2021), increasing the use of refuge sites (Semlitsch and Reyer 1992;Hartman and Lawler 2014), stimulating specific escape behaviors (Sousa et al 2011), and changing the habitat selection (Chuang et al 2019;Pacheco et al 2019).…”

Differential behavioral responses of benthic and nektonic tadpoles to predation at varying water depths

Predators influence microhabitat selection and activity level of tadpoles, but it is still unclear how such responses to predators differ among species and how water column's depth influences this predator-prey interaction. Here, we experimentally tested whether the presence of Odonata water-nymphs influenced spatial use and activity of benthic and nektonic tadpoles in different food availability contexts. Benthic tadpoles occupied and consumed more food at the bottom level, irrespective of predator’s presence. However, when predators were at bottom, benthic tadpoles remained close to the cages, suggesting a typical “stay-still” defensive behavior known for Physalaemus nattereri (Steindachner, 1863). Nektonic tadpoles occupied shallower depths on predator's presence, and they also consumed less food and avoided predator by selecting food sources far from it. When predator was at bottom level and food was available, the distance of tadpoles to the cage tended to be smaller. Scinax fuscovarius (Lutz, 1925) tadpoles were more active when food was absent regardless of predator’s presence. When food was available, these tadpoles generally occupied and consumed more food at bottom level. Tadpoles’ responses depended not only on predator’s presence, but on a complex net of factors, which include tadpoles’ habit, anti-predatory behavior, availability and location of food.

“…It is apparent that prey animals typically recruit sets of correlated behavioural and morphological anti-predator traits to avoid predation [reviewed in DeWitt and Langerhans (2003) and Bourdeau and Johansson (2012)]. Trait correlations among defensive traits have been studied in aquatic organisms like snails [e.g., Cotton et al (2004), Bourdeau (2009), Brönmark et al (2012), and Ahlgren et al (2015)], odonates [e.g., Mikolajewski and Johansson (2004) and Mikolajewski et al (2010)], amphibians [e.g., Hossie et al (2017) and Pacheco et al (2019)], and fish [e.g., Hulthén et al (2014), Kern et al (2016), and Marshall and Wund (2017)], as well as terrestrial organisms such as moths (Vogelweith et al, 2014), snakes (Mayer et al, 2016), and rodents (Agnani et al, 2020). Functionally and mechanically independent behavioural and morphological defences can either be negatively (trait compensation) or positively (trait cospecialization) correlated (DeWitt et al, 1999;DeWitt and Langerhans, 2003).…”

Predation is a key driver of phenotypic diversification with prey having evolved sets of correlated anti-predator traits. Changes in anti-predator traits can be studied on an evolutionary as well as on a developmental timescale. Using a common garden setup, we studied inter- and intraspecific correlations of behavioural and morphological defences in four damselfly species that either occur in habitats dominated by predatory fish (fish habitats) or fishless habitats by raising larvae either with predatory fish or in a control treatment. We found inter- as well as intraspecific trait compensation (negative correlations) between behavioural and morphological defences. Compared to fishless habitat species, fish habitat species invested more in behavioural defences and less in morphological defences. This was mirrored by fish habitat species investing more in behavioural defences and less in morphological defences when reared with predatory fish whereas fishless habitat species invested less in morphological defences only. Our results emphasise the role of context-specific combinations of defensive traits to avoid predation. We suggest, considering changes in multiple correlated traits on different timescales when studying the evolution of anti-predator traits.
