“…When studying the association of top predators – such as spiders – and plants, we can now expect that these relationships might be mediated by host plant traits, which could be of great ecological and evolutionary relevance. Previous studies have demonstrated that top predators are more sensitive to climate stability, habitat size, and complexity (Ledger et al ., ; Romero et al ., , ). Thus, by underlining the trait‐mediating spider–bromeliad association, we can provide information on how habitat specialisation and resource acquisition have been occurring in the Atlantic rainforest biodiversity hotspot.…”

1. Non‐trophic interactions between plants and animals can affect community structure and species trait composition. However, it is unclear how changes in intra‐ and interspecific morphological traits of plant species affect non‐trophic interactions at a metacommunity scale. Additionally, whether plant evolutionary history determines taxonomic and functional diversity of plant‐dwelling predators is an open question. 2. To address these gaps, this study used a published dataset with spiders dwelling exclusively on bromeliads to investigate if: (i) intra‐ and interspecific variability in host plant morphological traits affects spider taxonomic and functional diversity; and (ii) bromeliad trait evolution determines present‐day patterns of spider trait diversity. 3. Spider and bromeliad traits were measured, and a new statistical framework was used to quantify the response of spider beta diversity to intra‐ and interspecific variation in bromeliad traits. In addition, bromeliad traits were decomposed across its phylogenetic tree to check whether the current variation in morphological traits of bromeliads is a result of either ancestral or recent diversification. 4. Bromeliad intraspecific variation did not affect spiders, but leaf length variation between bromeliad species had a positive effect on spider functional beta diversity. Interestingly, the most ancestral split between two subfamilies explained most of the variation in bromeliad species, which suggests that spider functional diversity could represent an outcome of bromeliad evolutionary history. 5. Overall, the results of this study suggest that interactions between plants and organisms that do not feed directly on their tissues could be shaped by plant evolutionary history, which in turn suggests that non‐trophic interactions can be maintained over time.

“…This is known as the escalating arms race and is well documented in predatory venoms [15,41,[54][55][56]. As the frequency and the strength of biotic encounters decrease at high elevations due to colder climatic conditions [43,44,[57][58][59][60], a lower predator pressure is expected to be exerted on bumblebees at high elevations. Therefore, the reduced levels of PLA 2 -like at high elevations may be a consequence of energy expenditure modulation.…”

Alteration of Bumblebee Venom Composition toward Higher Elevation

Venomous animals use venom, a complex biofluid composed of unique mixtures of proteins and peptides, for either predation or defense. Bumblebees, which occur in various habitats due to their unique thermoregulatory properties, mainly use venom for defense. Herein, we conducted an exploratory analysis of the venom composition of a bumblebee species (Bombus pascuorum) along an elevation gradient in the western Swiss Alps using shot-gun proteomic approaches to assess whether their defense mechanism varies along the gradient. The gradient was characterized by high temperatures and low humidity at low elevations and low temperatures and high humidity at high elevations. Venom composition is changing along the elevation gradient, with proteomic variation in the abundances of pain-inducing and allergenic proteins. In particular, the abundance of phospholipase A 2 -like, the main component of bumblebee venom, gradually decreases toward higher elevation (lower temperature), suggesting venom alteration and thus a decrease in bumblebee defense towards harsher environments. Larger datasets may complement this study to validate the observed novel trends.

“…In some cases, the direct abiotic effects of climate change, such as elevated temperature, will strongly affect eco-evolutionary dynamics and population persistence through climate change. In other cases, indirect effects mediated through biotic interactions will be more consequential, leading to increased competition (Alexander et al, 2015), predation and herbivory (Brodie et al, 2012;Rasmann et al, 2014;Romero et al, 2018), as well as disrupted mutualistic interactions (Forrest, 2015). For example, plant populations and their herbivores can be reciprocally locally adapted (Garrido et al, 2012).…”

“…Evaluating how climate change will alter biotic interactions is crucial for generating robust predictions of population persistence. In addition to predicting species interactions in facing climate change (e.g., Romero et al, 2018;Ohler et al, 2020), scientists can protect against biodiversity loss due to climate change by identifying and preserving species that enhance local diversity, such as keystone species and ecosystem engineers (Bulleri et al, 2018).…”

Climate change poses critical challenges for population persistence in natural communities, for agriculture and environmental sustainability, and for food security. In this review, we discuss recent progress in climatic adaptation in plants. We evaluate whether climate change exerts novel selection and disrupts local adaptation, whether gene flow can facilitate adaptive responses to climate change, and whether adaptive phenotypic plasticity could sustain populations in the short term. Furthermore, we discuss how climate change influences species interactions. Through a more in‐depth understanding of these eco‐evolutionary dynamics, we will increase our capacity to predict the adaptive potential of plants under climate change. In addition, we review studies that dissect the genetic basis of plant adaptation to climate change. Finally, we highlight key research gaps, ranging from validating gene function to elucidating molecular mechanisms, expanding research systems from model species to other natural species, testing the fitness consequences of alleles in natural environments, and designing multifactorial studies that more closely reflect the complex and interactive effects of multiple climate change factors. By leveraging interdisciplinary tools (e.g., cutting‐edge omics toolkits, novel ecological strategies, newly developed genome editing technology), researchers can more accurately predict the probability that species can persist through this rapid and intense period of environmental change, as well as cultivate crops to withstand climate change, and conserve biodiversity in natural systems.
