Specialized and generalized non-material Nature’s Contributions to People: insights from tourists at Mount Kilimanjaro, TanzaniaNARA Subscribed
Nature contributes to our quality of life through a wide range of non-material Nature’s Contributions to People (NCP), including aesthetic enjoyment, restorative experiences and recreational opportunities. However, quantifying and managing the supply of non-material NCP requires a mechanistic understanding of how they are associated with the entities of nature that support them across different ecological contexts. We characte...
Projected Impacts of Climate Change on Interactions Between Plants and Avian Frugivores Across the AmericasNARA Subscribed
Aim Frugivorous birds provide crucial seed‐dispersal functions in terrestrial ecosystems. However, the impact of climate change on plant–avian frugivore interactions remains unclear due to past methodological limitations. In this study, we address this by mapping these interactions across the Americas and projecting shifts in interaction diversity under future climate scenarios. Location North, South, and Central America. Time...
Trait‐based approaches are key to understanding eco‐evolutionary processes but rarely account for animal behaviour despite its central role in ecosystem dynamics. We propose integrating behaviour into trait‐based ecology through movement traits—standardised and comparable measures of animal movement derived from biologging data, such as daily displacements or range sizes. Accounting for animal behaviour will advance trait‐base...
Constant herbivory rates and plant–herbivore interactions along a resource availability gradient in South African fynbosNARA Subscribed
Plant–herbivore interactions are important for almost all terrestrial ecosystems, but little is known about how herbivory and the specialization of these interactions change with the resource availability provided by host plant communities and time since disturbance. In fire-prone scrublands of the South African Cape Floristic Region, we studied interaction networks between 20 Protea shrub species and ten herbivorous insect sp...
A quantitative framework for identifying the role of individual species in Nature's Contributions to PeopleNARA Subscribed
It is widely acknowledged that biodiversity change is affecting human well‐being by altering the supply of Nature's Contributions to People (NCP). Nevertheless, the role of individual species in this relationship remains obscure. In this article, we present a framework that combines the cascade model from ecosystem services research with network theory from community ecology. This allows us to quantitatively link NCP demanded...
Trait diversity shapes the carbon cycleNARA Subscribed
Hummingbird community structure and nectar resources modulate the response of interspecific competition to forest conversionNARA Subscribed
On-going land-use change has profound impacts on biodiversity by filtering species that cannot survive in disturbed landscapes and potentially altering biotic interactions. In particular, how land-use change reshapes biotic interactions remains an open question. Here, we used selectivity experiments with nectar feeders in natural and converted forests to test the direct and indirect effects of land-use change on resource compe...
Avian seed dispersal may be insufficient for plants to track future temperature change on tropical mountainsNARA Subscribed
Aim Climate change causes shifts in species ranges globally. Terrestrial plant species often lag behind temperature shifts, and it is unclear to what extent animal‐dispersed plants can track climate change. Here, we estimate the ability of bird‐dispersed plant species to track future temperature change on a tropical mountain. Location Tropical elevational gradient (500–3500 m.a.s.l.) in the Manú biosphere reserve, Peru. Time p...
Species interactions are influenced by the trait structure of local multi‐trophic communities. However, it remains unclear whether mutualistic interactions in particular can drive trait patterns at the global scale, where climatic constraints and biogeographic processes gain importance. Here we evaluate global relationships between traits of frugivorous birds and palms (Arecaceae), and how these relationships are affected, dir...
Functional traits offer a rich quantitative framework for developing and testing theories in evolutionary biology, ecology and ecosystem science. However, the potential of functional traits to drive theoretical advances and refine models of global change can only be fully realised when species‐level information is complete. Here we present the AVONET dataset containing comprehensive functional trait data for all birds, includi...
A research framework for projecting ecosystem change in highly diverse tropical mountain ecosystemsNARA Subscribed
Tropical mountain ecosystems are threatened by climate and land-use changes. Their diversity and complexity make projections how they respond to environmental changes challenging. A suitable way are trait-based approaches, by distinguishing between response traits that determine the resistance of species to environmental changes and effect traits that are relevant for species' interactions, biotic processes, and ecosystem func...
High levels of phenological asynchrony between specialized pollinators and plants with short flowering phasesNARA Subscribed
Species phenology plays a key role in determining mutualistic interactions, such as those between plants and pollinators. Notably, temporal synchrony shapes the patterns of interactions by influencing the probability of encounters between interacting partners; thus, species phenology greatly contributes to structuring ecological communities. In these communities, specialized species are expected to show a high level of synchro...
Similar composition of functional roles in Andean seed‐dispersal networks, despite high species and interaction turnoverNARA Subscribed
The species composition of local communities varies in space, and its similarity generally decreases with increasing geographic distance between communities, a phenomenon known as distance decay of similarity. It is, however, not known how changes in local species composition affect ecological processes, that is, whether they lead to differences in the local composition of species' functional roles. We studied eight seed‐dispe...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...

Functional and phylogenetic diversity of bird assemblages are filtered by different biotic factors on tropical mountainsNARA Subscribed
Aim It is not yet clear whether similar mechanisms influence the assembly of ecological communities across different continents. Here, we investigated the functional and phylogenetic diversity of bird assemblages along elevational gradients in two biogeographic regions in order to identify how these are driven by biotic factors, such as food resources and vegetation structure, and abiotic factors, such as ambient temperature a...
