Abstract Changes in global and regional precipitation regimes are among the most pervasive components of climate change. Intensification rainfall cycles, ranging from frequent downpours to severe droughts, could cause widespread, but largely unknown, alterations trophic structure ecosystem function. We conducted multi-site coordinated experiments show how variation quantity evenness modulates 210 natural freshwater microcosms (tank bromeliads) across Central South America (18°N 29°S). The...
Although predators can affect foraging behaviors of floral visitors, rarely is it known if these top‐down effects may cascade to plant fitness through trait‐mediated interactions. In this study we manipulated artificial crab spiders on flowers Rubus rosifolius test the predation risk flower‐visiting insects and strength indirect fitness. addition, tested which predator traits (e.g., forelimbs, abdomen) are recognized avoided by pollinators. Total visitation rate was higher for control than...
Local habitat size has been shown to influence colonization and extinction processes of species in patchy environments. However, differ body size, mobility, trophic level, may not respond the same way size. Thus far, we have a limited understanding how influences structure multitrophic communities what extent effects be generalizable over broad geographic range. Here, used water-filled bromeliads different sizes as natural model system examine on their inhabiting invertebrate communities. We...
Abstract Functional traits are commonly used in predictive models that link environmental drivers and community structure to ecosystem functioning. A prerequisite is identify robust sets of continuous axes trait variation, understand the ecological evolutionary constraints result functional space occupied by interacting species. Despite their diversity role functioning, little known on invertebrate biotas entire biogeographic regions. We examined strategies underlying realized aquatic...
There is growing recognition that ecosystems may be more impacted by infrequent extreme climatic events than changes in mean conditions. This has led to calls for experiments explore the sensitivity of over broad ranges parameter space. However, because such response surface have so far been limited geographic and biological scope, it not clear if differences between studies reflect location or ecosystem component considered. In this study, we manipulated rainfall entering tank bromeliads...
Abstract Habitat size and climate are known to affect the trophic structure dynamics of communities, but their interactive effects poorly understood. Organisms from different levels vary in terms metabolic requirements heat dissipation. Indeed, larger species such as keystone predators require more stable climatic conditions than prey. Likewise, habitat disproportionally affects large‐sized predators, which home ranges thus restricted habitats. Therefore, food web patchy ecosystems is...
Warming is among the major drivers of changes in biotic interactions and, turn, ecosystem functioning. The decomposition process occurs a chain facilitative between detritivores and microorganisms. It remains unclear, however, what effect warming may have on interrelations microorganisms, consequences for functioning natural freshwater ecosystems. To address these gaps, we performed field experiment using tank bromeliads their associated aquatic fauna. We manipulated presence bacteria...
Although a wide variety of arthropods specialize on specific host plant, little is known about the evolution host–plant specialization in spiders. In several regions South America, Neotropical jumping spider Psecas chapoda associates with Bromelia balansae, rosette-shaped plant that does not accumulate rain water phytotelmata. We conducted experiments using bromeliad species distinct architectures were uncommon geographic range P. to investigate level microhabitat structure. also tested...
Abstract Aquatic ecosystems are tightly linked to terrestrial by exchanges of resources, which influence species interactions, community dynamics and functioning in both ecosystem types. However, our understanding how this coupling responds climate warming is restricted temperate, boreal arctic regions, with limited knowledge from tropical ecosystems. We investigated aquatic impact cross‐ecosystem the tropics, through export resources into environment breakdown within environment....
Abstract Herbivory is ubiquitous. Despite being a potential driver of plant distribution and performance, herbivory remains largely undocumented. Some early attempts have been made to review, globally, how much leaf area removed through insect feeding. Kozlov et al., in one the most comprehensive reviews regarding global patterns herbivory, compiled published studies foliar removal sampled data on levels using standardized protocol. However, review by only 15 sampling sites, comprising 33...
There are many examples of predators having specialized microhabitat requirements, but the sensory mechanisms by which detect, identify, and evaluate microhabitats only poorly understood. The ability to use visual cues select was investigated using Psecas chapoda, a bromeliad-dwelling salticid spider. In this study, we manipulated real plants photos test whether P. chapoda uses plant architecture host alone sufficient for them microhabitats. on experiment allowed us exclude potential...
Abstract Aim Locally abundant species are usually widespread, and this pattern has been related to properties of the niches traits species. However, such explanations fail account for potential determine often overlook statistical artefacts. Here, we examine how trait distinctiveness determines abilities exploit either common habitats (niche position) or a range breadth) niche position breadth, in turn, affect abundance occupancy. We also artefacts moderate these relationships. Location...
Summary The cascading effect of predators on the functioning adjacent ecosystems can occur when life cycles their prey include two ecosystems. However, there has been little consideration which habitat attributes modify strength these cross‐ecosystem trophic cascades. Habitat size mediate predator–prey interactions, and thus affect within‐ecosystem We hypothesise that similar effects might It shown terrestrial (e.g. spiders) capture adult insects as they attempt to oviposit in waters...
Abstract It has been argued that the mechanisms structuring ecological communities may be more generalizable when based on traits than species identities. If so, patterns in assembly of community‐level along environmental gradients should similar different places world. Alternatively, geographical change pool and regional variation climate might result site‐specific relationships between community local environments. These competing hypotheses are particularly untested for animal...
Abstract Animal community responses to extreme climate events can be predicted from the functional traits represented within communities. However, it is unclear whether geographic variation in response of structure change primarily driven by physiological matching local conditions (local adaptation hypothesis) or differences between species pools redundancy (insurance hypothesis). We conducted a coordinated experiment understand how aquatic invertebrate mediate multitrophic communities...
1. A key challenge in the study of mutualistic interactions is understanding sources variation that strengthen or weaken these interactions. In spider–plant mutualisms, spiders benefit plants by improving plant nutrition and protecting from herbivory. Although benefits to spider growth survival are often claimed, they rarely demonstrated. 2. this study, empirical evidence provided bromeliads ( Bromelia balansae , Bromeliaceae) essential for resilience bromeliad‐living jumping populations...
Functional traits determine an organism's performance in a given environment and as such which organisms will be found where. Species respond to local conditions, but also larger scale gradients, climate. Trait ecology links these responses of species community composition distributions. Yet, we often do not know environmental gradients are most important determining trait at either or biogeographical scales, their interaction. Here quantify the relative contribution climatic conditions...
Abstract Fluxes of energy, matter, and organisms sustain linkages functions within between ecosystems. Yet, how biological drivers influence interactions at the interface aquatic terrestrial environments (i.e., aquatic-terrestrial ecosystem functions) locally across regions has received little attention. To test relative importance on multiple functions, we subsidised local detritus in forested non-forested stream sites a temperate tropical region. We also manipulated leaf litter diversity...
Beta diversity patterns have been frequently used to investigate metacommunity structure. The concept has focused primarily on the spatial beta component, but part of unaccounted variation is likely associated with temporal patterns. Here, we examined effect seasonal in water availability spatiotemporal assembly microcrustaceans living temporary pools. Specifically, sampled 5 pools monthly for 12 mo and tested how fluctuations physicochemical variables affected diversity. We also...
